CHAPTER I
Introduction
The Patent System in India
1.2.2 In 1872, the Act of 1859 was revisited to provide protection relating to
designs. It was renamed as “The Patterns and Designs Protection Act” under Act
XIII of 1872. The Act of 1872 was amended in 1883 (XVI of 1883) to introduce a
provision to protect novelty of the invention, which prior to making application for
their protection were disclosed in the Exhibition of India (?). A grace period of 6
months was provided for filing such applications after the date of the opening of such
Exhibition.
1.2.3 This Act remained in force for about 30 years without any change but in
the year 1883, certain modifications in the patent law were made in United
Kingdom (UK) and it was considered that those modifications should also be
incorporated in the Indian law. In 1888, new legislation was introduced to
consolidate and amend the law relating to invention and designs in conformity with the
amendments made in the U.K. law. The modifications introduced in the Indian law,
by Act V of 1888, over the UK legislation, inter alia, includes:
7
• Extension of the jurisdiction of the Act to other courts apart from High
Courts of Madras, Calcutta and Bombay;
• Reduction in the fee;
• Provision for detailed disclosure of the invention, including best mode of
working the invention in full clear, concise and exact terms so as to enable
any person skilled in the art or science to make use of the invention;
• Provision of powers to call for a model of the invention;
• Change of time for filing petition in respect of patent granted in United
Kingdom from 12 months from the ‘letters patent’ to 12 months from the
‘date of sealing’;
• Extension of term of exclusive privileges to ------
• Provision for granting compulsory licence where invention is not made
accessible to public, on reasonable terms;
• Appointment of Agents to encourage filing by foreign inventor;
• Introduction of provision for protection of new or original design;
• Provision for counting the grace period for filing application for invention
displayed in the Exhibition from the date of admission of the invention into
the Exhibition instead of the date of the opening of the Exhibition.
1.2.4 In 1911, the Indian Patents and Designs Act, 1911, (Act II of 1911) was
brought in replacing all the previous Acts. This Act brought patent administration
under the management of Controller of Patents for the first time. This Act
was amended in 1920 to provide for entering into reciprocal arrangements
with UK and other countries for securing priority. In 1930, further
amendments were made to incorporate, inter-alia, provisions relating to grant
of secret patents, patent of addition, use of invention by Government, powers
of the Controller to rectify register of patent and increase of term of the
patent from 14 years to 16 years. In 1945, another amendment was made to
provide for filing of provisional specification and submission of complete
specification within nine months.
1.2.5 After Independence, it was felt that the Indian Patents & Designs Act,
1911 was not fulfilling its objective. It was found desirable to enact comprehensive
patent law owing to substantial changes in political and economic conditions in the
country. Accordingly, the Government of India constituted a committee under the
Chairmanship of Justice (Dr.) Bakshi Tek Chand, a retired Judge of Lahore High
Court, in 1949, to review the patent law in India in order to ensure that the patent
system is conducive to the national interest. The terms of reference included—
8
f) to consider the desirability or otherwise of regulating the profession of
patent agents
g) to examine the working of the Patent Office and the services rendered by
it to the public and make suitable recommendations for improvement; and
h) to report generally on any improvement that the Committee thinks fit to
recommend for enabling the Indian Patent System to be more conducive
to national interest by encouraging invention and the commercial
development and use of inventions.
1.2.6 The Committee submitted its interim report on 4th August, 1949 with
recommendations for prevention of misuse or abuse of patent right in India and for
amendments to sections 22, 23 & 23A of the Patents & Designs Act, 1911 on the lines
of the United Kingdom Acts of 1919 and 1949. The main recommendations of the
Committee were as follows:-
(a) Any interested person may apply for a compulsory licence or revocation of
the patent on any of the following grounds, namely—
1.2.7 The committee also observed that the Patents Act should contain clear
indication to ensure that food and medicine and surgical and curative devices are
made available to the public at the cheapest price commensurate with giving
reasonable compensation to the patentee.
1.2.8 Based on the above recommendation of the Committee, the 1911 Act was
amended in 1950 (Act XXXII of 1950) in relation to working of inventions and
compulsory licence/revocation. Following grounds were provided for making
applications for compulsory licence:
9
(a) patented invention, being capable of being commercially worked in India,
is not being commercially worked therein to the fullest possible extent;
(b) demand for the patented article in India is not being met to an adequate
extent or on reasonable terms;
(c) commercial working of the invention in India is being prevented or
hindered by the importation of the patented articles;
(d) the refusal of the patentee to grant a licence or licences on reasonable
terms, the commercial or industrial activities in India are prevented or
hindered;
(e) a market for the export of the patented article manufactured in India is not
being supplied;
(f) the working or efficient working in India of any other patented invention
which makes a substantial contribution to the establishment or development
of commercial or industrial activities in India is unfairly prejudiced; and
(g) conditions of licence unfairly prejudiced the establishment or development
of commercial or industrial activities in India.
The time period prescribed for making the applications was “at any time after
expiration of three years from the date of sealing.” The application could also be made
by the licencee. The term, ‘patented article’ included any article made by a patented
process. Other provisions were related to endorsement of the patent with the words
‘licence of right’ on an application by the Government so that the Controller could
grant licences. In 1952, an amendment was made to provide compulsory licence in
relation to patents in respect of food and medicines, insecticide, germicide or
fungicide and a process for producing substance or any invention relating to surgical
or curative devices, through Act LXX of 1952 . The compulsory licence was also
available on notification by the Central Government. Based on the recommendations
of the Committee, a bill was introduced in the Parliament in 1953 (Bill No.59 of
1953). However, the bill lapsed on dissolution of the Lok Sabha.
10
• No product patents for substances intended for use as food, drugs
and medicines including the product of chemical processes
• Codification of certain inventions as non-patentable
• Mandatory furnishing information regarding foreign application
• Adoption of absolute novelty criteria in case of publication
• Expansion of the grounds for opposition to the grant of a patent
• Exemption of certain categories of prior publication, prior
communication and prior use from anticipation
• Provisions for secrecy of inventions relevant for defence purposes
• Provision for use of inventions for the purpose of Government or for
research or instruction to pupils
• Reduction in the term of patents relating to process in respect of
substances capable of being used as food or as medicine or drugs
• Enlargement of the grounds for revocation of a patent
• Provision for non-working; as ground for compulsory licences,
licences of right, and revocation of patents
• Additional powers to Central Government to use an invention for
purposes of government including Government undertakings
• Prevention of abuse of patent rights by making restrictive conditions
in licence agreements/contract as void
• Provision for appeal to High Court on certain decisions of the
Controller
• Provision for opening of branches of the Patent Office
1.2.11 This Act remained in force for about 24 years without any change till
December 1994. An ordinance effecting certain changes in the Act was issued on 31st
December 1994, which ceased to operate after six months. Subsequently, another
ordinance was issued in 1999. This ordinance was later replaced by th he Patents
(Amendment) Act, 1999 that was brought into force retrospectively from 1st January,
1995. The amended Act provided for filing of applications for product patents in the
areas of drugs, pharmaceuticals and agro chemicals though such patents were not
allowed. However, such applications were to be examined only after 31-12-2004.
Meanwhile, the applicants could be allowed Exclusive Marketing Rights (EMR) to
sell or distribute these products in India, subject to fulfilment of certain conditions.
1.2.12 The second amendment to the 1970 Act was made through the Patents
(Amendment) Act, 2002 (Act 38 0f 2002). This Act came into force on 20th May
2003 with the introduction of the new Patent Rules, 2003 by replacing the earlier
Patents Rules, 1972. Salient features of the Patents (Amendment) Act, 2002 were--
• Further codification of non patentable inventions
• 20 years term of patent for all technology
• Provision for reversal of burden of proof in case of process patents
• Provisions of compulsory licences to meet public health concerns
• Deletion of provision of licence of right
• Introduction of system of deferred examination
• Mandatory publication of applications after 18 months from the date of
filing
• Provision for process patent for micro organisms
• Establishment of Appellate Board
• Provision for parallel imports
11
• Provision for exemption from infringement proceedings for use of a
patented invention for obtaining regulatory approval for a product based
on that patented invention
• Provision to protect biodiversity and traditional knowledge.
1.2.13 The third amendment to the Patents Act 1970 was introduced through the
Patents (Amendment) Ordinance, 2004 w.e.f. 1st January, 2005. This Ordinance was
later replaced by the Patents (Amendment) Act 2005 (Act 15 Of 2005 ) on 4th April,
2005 which was brought into force from 1st January, 2005. The salient features of this
amendment are-
1.3.2 There are four Schedules to the Patents Rules which provide details of fees
and forms pertaining to various types of actions required under Patents Act and Rules:
12
1.4 Administrative Structure of the Patent Office
1.4.1 Patent system in India is administered under the superintendence of the
Controller General of Patents, Designs, Trademarks and Geographical Indications
(CGPDTM), appointed under sub-section (1) of Section 3 of the Trade Marks Act,
1999. The Office of the Controller General of Patents, Designs and Trade Marks
functions under the Department of Industrial Policy and Promotion, Ministry of
Commerce and Industry. The Office of the CGPDTM is located at Mumbai. There
are four Patent Offices in India. The Head Office is at Kolkata and other Patent
Offices are located at Delhi, Mumbai and Chennai. The Controller General of Patents,
Designs and Trade Marks delegates his powers to Senior Joint Controller of Patents &
Designs, Joint Controllers of Patents & Designs, Deputy Controllers of Patents &
Designs and Assistant Controllers of Patents & Designs regarding various procedures
for patent grant. Examination of patent applications is done by Examiners of Patents
& Designs.

CHAPTER - II
PREAMBLE AND DEFINITIONS
2.1.1 The Patents Act was enacted by the Government of India in the year 1970 in
pursuance of its powers under Entry 49 of the List I of Schedule VII of the
Constitution of India. List I contains the list of the items in the Union List and
Entry 49 reads, “Patents, inventions and designs; copyright; trade-marks and
merchandise marks.” The Act was notified on 19th September 1970 as Act 39
of 1970.
2.1.2 The word ‘amend’ is used to indicate the fact that patent law was in existence
before the enactment of the Patents Act, 1970. The history of patent
legislations in India is given in Chapter-I. Enactment of a new legislation
while repealing the previous legislations does not de-legitimise the patents
granted and other action taken under the previous law [see section 162(3) and
(5)].
2.1.3 In the statement of objects and reasons of the Patent Bill, 1970, it is stated, “a
need for a comprehensive law so as to ensure more effectively that patent
rights are not worked to the detriment of the consumer or to the prejudice of
trade or the industrial development of the country was felt as early as 1948”.
This gives fair indication to the intention of the Act. The patents law is also
kept in line with the “development of technological capability in India,
coupled with the need for integrating the Intellectual Property system with
international practices and intellectual property regimes,” as stated in the
statement of objects and reasons of the Patents (Second Amendment) Bill,
1999. “The object of the patent law is to encourage scientific research, new
technology and industrial progress. Grant of exclusive privilege to own, use
or sell the method or the product patented for the limited period, stimulates
new inventions of commercial utility. The price of the grant of the monopoly
is the disclosure of the invention at the Patent Office, which after the expiry of
the fixed period of the monopoly passes into public domain.“ [Bishwanath
Prasad Radhey Shyam vs. H.M. Industries A.I.R. 1982 S.C. 1444 at paragraph
17].
14
the commencement of this Act shall be construed as a reference
to the coming into force of that provision.
2.2.1 The applicability of the Patents Act extends to the whole of India. A patent
granted as per the Act can only be enforced in the territorial limits of India,
subject to the provisions of section 49 of the Act. Patents granted as per this
Act only are valid in India.
2.2.2 Proviso to sub section 3 enables the Government to bring into force different
provisions of the Act at different times. For instance, provisions relating to
Appellate Board vide sections 116-117H were brought into force from 2nd
April, 2007 although other provisions had been brought into force earlier. The
Patent Office is required to act under the provisions of a particular section
only from the date those provisions are brought into force.
2.3 Definitions
Section 2. Definitions and interpretation.—
(a) "Appellate Board" means the Appellate Board referred to in section 116;
2.3.1 The reference is to the Intellectual Property Appellate Board (IPAB), Chennai.
Provisions relating to the IPAB were brought into force with effect from 2nd
April, 2007.
15
(b) "Controller" means the Controller General of Patents, Designs and
Trade Marks referred to in section 73;
(c) "convention application" means an application for a patent made by
virtue of section 135;
2.3.4 The omitted clause (g) read, “’food’ means any article of nourishment for
human consumption and also includes any substance intended for the use of
infants, invalids or convalescents as an article of food or drink;”
(i) "High Court", in relation to a State or Union territory, means the High Court
having territorial jurisdiction in that State or Union territory, as the case
may be;
(ia) "international application" means an application for patent made in
accordance with the Patent Cooperation Treaty;
2.3.5 India became a member of the Patent Cooperation Treaty on 7th December,
1998.
(j) "invention" means a new product or process involving an inventive step and
capable of industrial application;
2.3.6 Considering the question what is an ‘invention’. It was held in Raj Parkash vs,
Mangat Ram Choudhary as under:
“Invention is to find out or discover something not found or discovered by
anyone before and it is not necessary that the invention should be anything
complicated and the essential thing is that the inventor was the first one to
adopt it and the principle therefore is that every simple invention that is
16
claimed, so long as it is something novel or new, would be an invention and
the claims and the specifications have to be read in that light and a new
invention may consist of a new combination of all integers so as to produce
a new or important result or may consist of altogether new integers and the
claims for anticipation by the defendant has to be either by prior user or by
prior publication”
It was further observed that ‘whether a patent sets out an invention is to be
determined by a true and fair construction of the specifications and the
claims and in construing the specifications it would be erroneous to rely too
much on the title thereof because the title cannot control the actual claim and
a misleading title similarly is of no consequence and the words of the
specifications should be given their ordinary meaning but where necessary
must be construed in the sense in which they are used in a particular trade or
sphere in which the invention is sought to have been made and it is the pith
and marrow of the invention that has to be looked into and one should not
get bogged down or involved in the detailed specifications and claims made
by the parties who claim to be patentee or alleged violators.
2.3.7 A patent has been held a movable property by the Supreme Court in Appeal
(Civil) 4552 Of 1998 in the matter of M/S. Sunrise Associates Vs Govt.
Of NCT Of Delhi & Ors, on 28th April, 2006. The court held that it
considered the definition of "goods" in the constitution, in the Sales of
Goods Act 1930, the Central Sales Tax Act, 1956, the Tamil
Nadu General Sales Tax Act, 1959, the Karnataka Sales Tax Act, 1957,
as well as the Kerala General Sales Tax Act, 1963 and said that all these
definitions provided that goods mean inter alia all kinds of moveable
property. The definition of property in several authorities was
thereafter considered and it was concluded that the material on record
showed a uniform emphasis on the expansive manner in which the
expression 'property' was understood. It was noted that debts,
contracts and other choses (sic) in action were chattels no less than
furniture or stock in trade. Similarly, patents, copyrights and other rights
in rem were also included within the meaning of moveable property.
17
2.3.8 In Writ Petition (Civil) 12598 Of 1985 in the matter of Shri Kirshna Gyanoday
Sugar Ltd. & Anr. Vs. State Of Bihar, the Supreme Court referred to
R.C.Cooper's Case in the following words:
In its normal connotation "property" means "highest right a man can have to
anything, being that right which depend on another's courtesy: It includes
ownership, estates and interests in corporeal things, and also rights such as
trade-marks, copyrights, patents and even rights in personam capable of
transfer or transmission, such as debts; and signifies a beneficial right to or a
thing considered as having a money value.” (Date Of Judgment: 18th February,
2003.)
2.3.9 Unlike other property rights, a patent right may be revoked, amended or
abandoned.
(n) "patent agent" means a person for the time being registered under this Act
as a patent agent;
(o) "patented article" and "patented process" means respectively an article
or process in respect of which a patent is in force;
(oa) "Patent Cooperation Treaty" means the Patent Cooperation Treaty done at
Washington on the 19th day of June, 1970 as amended and modified from
time to time;
(p) "patentee" means the person for the time being entered on the register
as the grantee or proprietor of the patent;
(q) "patent of addition" means a patent granted in accordance with section
54;
(r) "patent office" means the patent office referred to in section 74;
2.3.10 The head office of the Patent Office is located at Kolkata and the branch
offices at Chennai, Delhi and Mumbai.
18
(y) "true and first inventor" does not include either the first importer of an
invention into India, or a person to whom an invention is first
communicated from outside India.
2.3.11 In the matter of application for patent no. 122013 and in the opposition
proceeding under Section 25 between Ganesh Mulji Rikabchand (applicant) v
Mischmetal and Flints Limited (opponent) DPD, VOL.1, P.126, the
Controller held that the application was not allowable because the applicant
has filed the application after being communicated from abroad. Section
2(1)(y) specifically excludes from the definition of “true and first inventor” a
person to whom an invention has been communicated from outside India.
Under Section 6 only a “true and first inventor” or his legal successor in title
may apply for patent.
(2) In this Act, unless the context otherwise requires, any reference—
(a) to the Controller shall be construed as including a reference to any
officer discharging the functions of the Controller in pursuance of
section 73;
(b) to the patent office shall be construed as including a reference to any
branch office of the patent office.
2.3.12 The definitions given in the above section are to be kept in view while interpreting the
provisions of other sections of the Act.
Rule 2: Definitions
19
2.4.2 The Patents Rules also provide certain definitions under Chapter-III relating to international
applications under Patent Cooperation Treaty.
2.4.3 Definitions and Interpretations underwent changes and additions during the various
amendments to the Act and Rules to meet with the requirements of the changing scenario.
20
CHAPTER – III
3.1 Introduction
a. It must be novel
b. It must have an inventive step and
c. It must be capable of industrial application.
Further, the invention should not fall under any of the categories of
“Inventions- non-patentable” mentioned under Sections (3) and (4) of the
Patents Act, 1970.
3.2.2 Although the term “State of art” has not been defined under the Patents Act,
the following general principles are applied to determine the novelty of the
invention during the examination procedure by applying provisions of section
13, read with the provisions of sections 29 to 34 (see Chapter IV also).
21
3.3 Determination of Novelty
3.3.2 Novelty is determined before inventive step because the creative contribution
of the inventor can be assessed only by knowing the novel elements of the
invention.
3.3.5 The state of the art in the case of an invention shall be taken to comprise all
matter (whether a product, a process or information about either etc ) which has at
any time before the priority date of that invention been made available to the
public by publication of description (whether in India or elsewhere) or by
use in India.
3.3.6 Care should be taken when relying on dimensions derived from
drawings. Although features shown solely in a drawing form part of the state
of the art when a skilled person could derive a technical teaching from
them without further description, it is not generally possible to derive
a technical teaching by measuring dimensions in a diagrammatic
representation; and that dimensions under these circumstances do not
therefore form part of the state of the art [T204/83 (OJEPO 10/85 ) ]
3.3.7 In the matter of Graf & CIE AG and Maschinenfabrik Rieter Ag vs Nitto Shoji
Limited during pre-grant opposition proceedings of Application No.
422/Cal/2000 under Section 25(1), the Controller held, “..a prior art drawing
may be taken into consideration as a prior art disclosure if it discloses the
essential features of the impugned claim in a sufficiently and clearly
understandable manner to a skilled person and also if the drawing is such that
it provides an enabling disclosure either explicitly or implicitly”.
22
3.3.73.3.8 Matter becomes part of the state of the art on the date it first
becomes available to the public, wherever in the world this may be, and
whatever manner or language the disclosure takes place. There is no limit on
the age of the disclosure.
3.3.83.3.9 Different claims may have different priority dates of documents, such as
patent specifications, textbooks or technical journals which have been
published in the conventional sense of that term, for example, by being on sale or
available in libraries.
3.3.93.3.10 Any document is regarded as having been published, and thus forming
part of the state of the art, if it can be inspected as of right by the public,
whether on payment of a fee or not; this includes, for example, the
contents of the "open" part of the file of a patent application once the
application has been published.
3.3.11 Prior publication does not however depend on the degree of dissemination. The
communication to a single member of the public without inhibiting fetter is
enough to amount to making available to the public (Bristol-Myers Co's
Application, [1969] RPC 146). There is no need even to show that a
member of the public has actually seen the document. F o r e x a m p l e , i n
M o n s a n t o Brignac’s) Application, [1971] RPC 153, it was held that a company
had published a document by supplying it to its salesmen, since it had been given
to them with no restriction on disclosure; indeed it had been put into their
hands with the intention that they should make the information available
to the public.
3.3.12 The invention lacks novelty if information about anything falling within its
scope has already been disclosed. Thus, for example, if a claim
specifies alternatives or defines the invention by reference to a range of
values (e.g. of composition, temperature etc), then the invention is not new
if one of these alternatives, or if a single example falling within this range,
is already known. Thus a specific example is sufficient to destroy the
novelty of a claim to the same thing defined generically. For example,
disclosure of a metal coil spring anticipates a claim to resilient means. On
the other hand, a generic disclosure does not impugn the novelty of a more
specific claim, so that an earlier reference to a metal coil spring cannot be
used to attack the novelty of a claim specifying such a spring made of
copper. In some cases however the disclosure of a comparatively small and
restricted field of possible alternatives might properly be held to be a
disclosure of each and every member; for example, "fluid" may be taken to
disclose both liquid and gas, if the context warrants it, and a reference to an
electric motor may be regarded as disclosing the use of both series- and shunt-
wound types.
Example 1:
The subject matter disclosed prior to the filing of patent application will
destroy the novelty of the invention. To constitute a prior disclosure of a
23
patent, the matter relied upon as prior art must disclose subject matter which,
if performed, would necessarily result in infringement of the patent.
This infringement test is detailed by the Court of Appeal in General Tire &
Rubber Company v Firestone Tyre & Rubber Company Limited, [1972] RPC
457, at pages 485 " If the prior inventor's publication contains a clear
description of, or clear instructions to do or make, something that would
infringe the patentee's claim if carried out after the grant of the
patentee's patent, the patentee's claim will have been shown to lack the
necessary novelty, that is to say, it will have been anticipated”
"If, on the other hand, the prior publication contains a direction which is
capable of being carried out in a manner which would infringe the patentee's claim, but
would be at least as likely to be carried out in a way which would not do so,
the patentee's claim will not have been anticipated, although it may fail on
the ground of obviousness. To anticipate the patentee's claim the prior
publication must contain clear and unmistakable directions to do what the
patentee claims to have invented ... A signpost, however clear, upon the
road to the patentee’s invention will not suffice. The prior inventor must
be clearly shown to have planted his flag at the precise destination before the
patentee".
Example 2 :
Example 3 :
It was held in the case of Gujarat Reclaim & Rubber Products Ltd.v.Kamani
Metallic Oxides Ltd., (1983 PTC 105 (Bombay), that in a plea of prior public
knowledge and prior public use by opponents, the opponents have to establish
that the invention claimed in any of the claims of the applicants (complete
specification) was a public knowledge and that the invention was in use
publicly in India before the priority date of the claim i.e. 4-2-1976. The
opponents have not given any evidence in support of this ground except
referring to the documents relied upon by them under the ground of prior
publication. While considering ground of prior publication, documents relied
upon by the opponents are not relevant as they do not anticipate the applicants'
invention. Opponents have therefore failed to establish their case in this
ground.
Example 4 :
In the matter of M/s. Crompton Greaves Ltd. Mumbai V/s. M/s. Bharat Heavy
Electricals Ltd. Hyderabad, patent application No.221/BOM/96 (184657), it
was held by the Controller that the ground that the invention was publicly
known or publicly used in India was not established by the opponent since the
photo copies submitted by the opponent stated mainly the terms and conditions
24
of a contract to supply 3900 KVA & 5400 KVA traction transformers. The
photocopies of work order did not define any constructional features of the
traction transformer. Only by stating that they are the first in the field of
manufacturing, the applicant company cannot be stopped from obtaining a
patent unless the opponents establish that they were manufacturing an identical
product before the date of filing.
Example 5 :
Example 6 :
Example 7 :
25
Example 8 :
In T 303/86 (CPC Int) [1993] EPOR 241, the Technical Board of Appeal of
the EPO considered anticipation arising from two cook-book recipes of a
process for making flavour concentrates from vegetable or animal
substances by extraction with fat solvents under pressure in the presence
of water. The claim specified certain parameters for the ratio between the
vapour pressure of the water in the meat or vegetables and the vapour
pressure of the free water. It was observed that "It is sufficient to destroy the
novelty of the claimed process that this process and the known process are
identical with respect to the starting material and reaction conditions
since processes identical in these features must inevitably yield identical
products." Furthermore, it did not matter that the cook had not realised
that he was not only frying a chicken, but also making a "flavour
concentrate" in the surplus oil. It was enough, as the Board said, that
"some flavour of the fried chicken is extracted into the oil during the frying
process even if this is not the desired result of that process."

3.5.13.5.1 For establishing anticipation by the prior art, the prior invention should
be sufficiently disclosed so that a person skilled in the art is able to work the
invention without undue burden of experimentation.
3.5.3 Thus the requirement of sufficiency of the disclosure and enablement with
28
regard to prior art is different. In particular, the role of the person skilled in
the art is different. In the case of sufficiency, the skilled person is taken to
be trying to understand what the author meant. His common general
knowledge forms the background in construing the disclosure, with the patent
being construed on similar principles. Once this is performed, to determine
whether or not the disclosure would infringe, the person skilled in the art has
no further part to play. On the other hand, for enablement, the person skilled in the art is
assumed to be willing to make trial and error experiments to get it to work,
and the question is not what the skilled person would think the disclosure
meant, but rather whether he would be able to work the disclosed invention.
3.6.1 Prior public use of the invention in India before the date of filing of
application destroys the novelty of the invention. However, there is an
exception to this general rule. The Act provides that if an invention has been
publicly worked in India within one year before the priority date by the
patentee or applicant for the patent or by any third person from whom he
derives the title or by the person who has obtained a consent to work the
invention and such working of invention was only for the purpose of
reasonable trial and it was necessary to effect such trial or working in public in
view of the nature of the invention then such working of invention does not
anticipate the invention (Section 32).
3.6.2 Public user does not mean a user by the public but a user in a public manner
(Lallubhai Chakubhai v. Chimanlal Chunilal & Co. 37 Bom L.R. 665).
Example 1:
In Lallubhai Chakubhai v. Chimanlal Chunilal & Co. A.I.R., 1936 Bom. 99,
it was held that public user does not mean a user by the public but a user in a
public manner. It was further held that the use of an invention for purposes
of trade, whether by the inventor himself or by others, may constitute public
user of the invention. It was also held that public sale of articles is strong
evidence that the user is commercial and not experimental. But to constitute
evidence of public user, the sale must be open and in the ordinary way of
business.
Example 2:
Example 3:
29
was held that if an article manufactured under a secret process is of such a
character that any body by examining it can find out the secret of that
manufacture, then the sale of that article in public would amount to public
user of the process. It was also held that secret use of an invention by the
inventor himself for experimental purposes of the manufacture of an
invention for the inventor by a manufacturer, who is under injunction to keep
the invention secret will not make the patent invalid.
Example 4:
In Monsanto Co. V. Coromandel Indag Products (P) Ltd. 1986 A.I.R. 712, it
was held that “to satisfy the requirement of being publicly known as used in
clauses (e) and (f) of section 64(1), it is not necessary that it should widely
used to the knowledge of the consumer public. It is sufficient if it is known
to the persons who are engaged in the pursuit of knowledge of the patented
product or process either as men of science or men of commerce or
consumers.“
Example 5:
Example 6:
Example 7:
In Lux Traffic Controls Ltd v Pile Signals Ltd and Faronwise Ltd, [1993]
RPC 107 Aldous J recognized that what was made available to the public
often differed according to whether the public had an article in their
possession to handle, measure and test or whether they could merely
look at it. Depending on the circumstances a skilled person might be able
to determine how an article was constructed and operated or nothing
material might be disclosed.
30
Novelty is destroyed by prior use of a product if analysis of the product
using available techniques shows the skilled person that it falls within the
scope of the claims (T952/92 OJEPO 11/1995).
Example 8:
In the case of Ram Narain Kher v. Ambassador Industries, (AIR 1976 Del 87.),
it was held that At the time the patent is granted to a party it is essential that the
party claiming patent should specify what particular features of his device
distinguish it from those which had gone before and show the nature of the
improvement which is said to constitute the invention. A person claiming a
patent has not only to allege the improvement in art in the form but also that
the improvement effected anew and very useful addition to the existing state
of knowledge. The novelty of the invention has to be succinctly stated in the
claim. It is no doubt true that the claim made is addressed to the skilled
persons in the art or trade and not to a common man yet there can be no
escape from the fact that the novelty of the claim or the advantage derived by
the invention has to be succinctly stated in the claim and must not be left to an
inference raised on a general review of the specification. It is equally true that
even when the invention 'was not itself new', 'the particular use of it for the
purpose described in combination with the other elements of the system, and
producing the advantageous results', would be a sufficient element of novelty
to support the patent. It may be only a small step but that may be a step
forward and that is all that is necessary so far as the subject-matter is
concerned.
Example 9:
In Staridipack Private Limited v. Oswal Trading Co. Ltd (1999 (19) PTC 479
(Del)) the invention was related to thickness of the layers of pouch. The issue
was about “the thickness of plastic film/layer depends upon the tolerance of
the contents in the pouch”. It was held that the invention is merely an
arrangement and rearrangement of the items and cannot be termed as a novel
concept and does not have any novelty. Such arrangement and rearrangement
of mixture of the materials cannot become an invention, for it is only an
improvement by adding microns as per the strength of the layers. Thus, prima
facie the invention claimed by the plaintiff in respect of the thickness of the
layers of the aforesaid pouch cannot be called an invention as envisaged
within the definition clause of the Patents Act. Besides, the documentary
evidence placed on record prima facie indicates that the claim made by the
plaintiff is already known in the trade and the patent was pre-published.
Example 10:
In Milliken Denmark AS v Walk Off Mats Ltd and anr [1996] FSR 292
Jacob J held that the hiring of mats to customers who were free to inspect
them amounted to anticipatory prior use even though the mats relied on
perforations not visible to the naked eye for their function. While there was
no reason to suppose that any customer should have conducted tests which
would have revealed the perforations, a skilled person called on to
investigate the mats would none the less have discovered them. The knowledge of the
31
perforations would enable the skilled person to perform the invention. It
was irrelevant that he would not know of its virtues. Moreover, if the
process by which the article or material has been made can be deduced with
certainty from such examination, that would also form part of the state of the
art.
Example 11:
Example 12:
In patent application No.26209, the Controller held that prior use of machine
for profit in private premises amounts to public use within the meaning of
section 9(1) (d), if the machine is worked in the ordinary way and under no
conditions of secrecy.

Example 18:
Section 13. Search for anticipation by previous publication and by prior claim
(1) The examiner to whom an application for a patent is referred under section 12
shall make investigation for the purpose of ascertaining whether the invention
so far as claimed in any claim of the complete specification –
… … … (b) is claimed in any claim of any other complete specification published
on or after the date of filing of the applicant’s complete specification, being a
33
specification filed in pursuance of an application for a patent made in India and
dated before or claiming the priority date earlier than that date.
3.7.1 In order to prove prior claiming of the invention, following conditions should
be complied with:--
(i) that the application(x) where the invention has been claimed prior to the
application(y) claiming alleged invention, has been filed in India
(ii) the application(x) must have been filed earlier to the date of filing or
priority date of application(y) in question
(iii) the application(x) should have been published on or after the date of
application(y) in question.
3.7.2 In the matter of application for patent no. 123140, Centron Industrial Alliance
Private Limited v Harbans Lal Malhotra and Sons Private limited, [DPD,
Vol.1, p 133], application filed on 15th September 1969 in respect of “
Improvements in or relating to blades of razors and like instruments.”
Claimed in Claim1:A method of manufacturing. superior quality blades of
razors and like instruments as herein defined, which includes coating the
blades with polytetrafluoroethylene, characterised in that the said method
consists of atomic or molecular deposition in vacuum of a thin film of
particles of a corrosion resistant material on the cutting edge or edges of the
blades of the said instruments before coating the said blades with said
polytetrafluoroethylene.
Prior filed application 120345 filed on 14th March 1969 cited for prior
claiming claimed in claim 1: A method of manufacturing. superior quality
blades of razors and like instruments as herein defined, which consists atomic
or molecular deposition in vacuum of a thin film of particles of a corrosion
resistant material on the cutting edge or edges of the blades of the said
instruments and thereafter coating the said blade with polytetrafluoroethylene.
Prior art filed application 120651 of 31st March 1969 was found anticipating
by prior claiming in part. 120651 claimed Rhodium as deposited material on
the cutting edges of the blade instead of a general expression “corrosion
resistant material” of impugned claim. The only difference of ‘651 was the use
of Rhodium as a thin film of particle deposited. The Controller observed that
the characteristic property of Rhodium is identical with the identical property
of corrosion resistant material. This lead to the conclusion that the claim at
issue was anticipated by cited document in part by prior claiming.
In the similar manner 120652 (31st March 1969) used platinum and was held
as anticipating in part by prior claiming.
34
118127 (16th October 1968) used razor blades made of carbon steel or
haedened stainless steel having a coating of chromium. This was also, held as
anticipating in part by prior claiming.
(3)3. the selection must be in respect of a quality of special character which can
fairly be said to be peculiar to the selected group. However, this is not
necessarily nullified if it transpires that some other members of the class from
which the selection is made have this quality, but the claim may be invalid if it
is found that the quality is common to many other members in addition to those
selected (IG Farbenindustrie AG's Patent, 47 RPC 289 P.322).
35
3.9 INVENTIVE STEP (NON-OBVIOUSNESS)
3.9.1 After establishing the novelty, an invention is assessed for inventive step. The
invention is not considered to involve an inventive step, if it is obvious to a
person skilled in the art on the date of priority. This is assessed on the basis of
published documents or otherwise. Inventive Step is defined in the Act as
under:
Section 2(1)(ja)
3.10.1 The Supreme Court laid down the following criteria for assessing inventive
step in M/s. Bishwanath Prasad Radhey Shyam Appellant v. M/s. Hindustan
Metal Industries, Respondent: “It is important that in order to be patentable an
improvement on something known before or a combination of different matters
already known, should be something more than a mere workshop
improvement; and must independently satisfy the test of invention or an
‘inventive step’. To be patentable the improvement or the combination must
produce a new result, or a new article or a better or cheaper article than before.
The combination of old known integers may be so combined that by their
working interrelation they produce a new process or improved result. Mere
collection of more than one integers or things, not involving the exercise of any
inventive faculty, does not qualify for the grant of a patent.” [AIR 1982
Supreme Court 1444]
3.10.2 In Canadian General Electric Co. Ltd., v. Fada Radio Ltd. A.I.R., 1930. PC.I.,
it was held that under the general law of patents, an invention, which consists
of a small inventive step but having regard to the conditions of the art,
constitutes a step forward, may be good subject matter for a patent.
3.10.3 There should be intellectual effort with respect to prior art technology to
develop the invention. Whereas the novelty considers whether the invention is
new with respect to prior art. The determination of inventive step goes further
and determine the quantum of improvement is sufficient to warrant a grant of
patent. By virtue of this determination a meritorious invention will be
differentiated from mere workshop improvement in the area of technology
under consideration. For determination of novelty an exact citation in a single
36
document is necessary. In the case of obviousness many documents can be
considered.
3.10.4 In Gillette Industries Ltd., v. Yeshwant Bros. A.I.R., 1938. Bom. 347., it was
held that mere simplicity is not necessarily an objection to the subject matter of
an invention, though matters of ordinary skilled designing or mere workshop
improvements are not inventions.
3.10.5 When the invention is just an automatic or obvious extension of Prior Art, the
invention lacks in inventive step.
3.10.7 The question is therefore, does the invention make available to the person
skilled in the art something that he would not reach by normal exercise of his
skill? If so, the inventor has made a contribution to the art which provides the
consideration justifying the grant of a patent. This is not to say that it must
be technically complex; simplicity does not count against an invention .
But there is no invention in appreciating commercial features alone , for
example in realizing that there is a market for a new product, however
surprising this may be.
3.10.8 Just as an invention will lack novelty if the claim to it would re-monopolize
something already disclosed, likewise it will be regarded as obvious if a
claim to it would inhibit the rights of a skilled workman to carry out routine
modifications of what is already in the public domain
3.10.9 For anticipation it is seen that it would be wrong to enable the patentee to
prevent a man from doing what he has lawfully done before the patent was
granted. In a similar way, the consideration behind obviousness is that it
would be wrong to prevent a man from doing something which is merely an
obvious extension of what he has been doing or of what was known in the art
before the priority date of the patent granted [1985] RPC 59, p. 77)
3.10.10 The term "obvious" means that which does not go beyond the normal progress
of technology but merely follows plainly or logically from the prior art, i.e.
something which does not involve the exercise of any skill or ability beyond
that to be expected of the Person Skilled in the Art.
3.10.11 For this purpose a Person Skilled in the Art should be presumed to be an
ordinary practitioner aware of what was general common knowledge in the
relevant art at the relevant date. In some cases the Person Skilled in the Art
may be thought of as a group or team of persons rather than as a single person.
3.10.12 Some examples to illustrate the points mentioned above are given below:
37
Example 1:
Example 2:
In another case which was decided by the Patent Office was related to a
hardening composition comprising (i) an unsaturated polyester resin (ii)
hardening accelerator containing cobalt metal soap and (iii) methyl ethyl
ketone peroxide as hardener. The two patent documents were submitted by
the opponent wherein document one was disclosing a hardening composition
comprising (i) unsaturated polyester resin, (ii) hardening accelerator
containing three component cobalt metal soap, calcium metal soap & copper
metal soap and (iii) tertiary butyl per-benzoate as a hardener. The document
two was disclosing the method of hardening of unsaturated polyester resin
using peroxides such as methyl ethyl ketone peroxide, tertiary butyl per
benzoate which can function as a hardener. The Controller held the
invention obvious in view of the disclosure in the two cited documents as it
was obvious to a person skilled in the art to use tertiary butyl per benzoate as
hardener in the hardening composition.
38
provided they are all in the same art. In Dow Chemical Company
(Mildner's Patent), [1973] RPC 804, Whitford J indicated that in
order to establish obviousness in such a case it is necessary to be
able to conclude that the documents are ones which the seeker after
information would come across and would consider together.
39
i. The invention must be considered as a whole for consideration of
inventive step. It is thus not sufficient to draw the conclusion that a
claimed invention is obvious merely because individual parts of the
claim taken separately are known or might be found to be obvious.
3.12.1 The examiner (or any other person) who is considering the question of
whether or not an invention is obvious must beware of ex-post facto analysis.
It can be very easy to be misled by a line of reasoning involving taking the
solution and working backwards to the problem by a succession of easy
steps. In considering a prior publication the examiner must avoid looking
at the document under the influence of the application he is examining,
and should attempt to place himself in the shoes of the skilled person faced
with the problem at hand.
40
ii) The fact that an individual feature or a number of features were known from
prior art does not conclusively show the obviousness of a combination (T 37/85,
T 666/93, T 1018/96); but whether the state of the art would lead a skilled
person to this particular overall combination of possibly already known features.
In such a case, it would be impossible for a combination consisting exclusively
of known individual features to involve an inventive step (T 388/89, T 717/90,
T 869/96).
iv) In T 406/98 the board found that as a rule, particularly when large numbers of
citations were involved, it was necessary to ask why the skilled person would
consider documents in that specific combination, and whether, not knowing the
invention, he had reason to do so. In this case, a complete solution to the
problem required deliberate selection from a large number of citations.
vi) It was held that there was no inventive step in combining the claim's two
features, both known per se, since they related to the solving of two entirely
separate partial problems and the solutions could be assessed separately against
the prior art [ T 597/93, T 687/94]
The following aspects need to be looked into while determining inventive step in
the alleged invention :
41
success was due to the technical merits of the development? (Haverman vs
Jackal (1999) FSR 685 at 699-701)
a. Determining scope and content of the prior art to which the invention pertains
b. Assessing the technical result (or effect) and economic value achieved by the
claimed invention
c. Assessing differences between the relevant prior art and the claimed invention
d. Defining the technical problem to be solved as the object of the invention to
achieve the result
e. Final determination of non-obviousness, which is made by deciding whether
a person of ordinary skill could bridge the differences between the relevant
prior art and the claims at issue.
ii) He should also be presumed to have had access to everything in the state of
the art, in particular the documents cited in the search report, and to have had
at his disposal the normal means and capacity for routine work and
experimentation
iii) Such person should not possess any inventive capability. It was the presence of
such capability in the inventor, which set him apart from the notional skilled
person. His attitude is considered to be conservative. He would never go
42
against an established prejudice, nor try to enter unpredictable areas nor take
incalculable risks.
iv) The skilled person can be expected to look for suggestions in neighbouring
fields if the same or similar problems arise in such fields. The skilled person
can be expected to look for suggestions in a general technical field if he is
aware of such fields. The notional skilled person would perform a transfer of
technology from a neighbouring field to his specific field of interest, if this
transfer involved routine experimental work comprising only routine trials
Example 1
In Tetra Molectric Ltd v Japan Imports Ltd ([1976] RPC 547) the Court of
Appeal held that a claim to a smoker's lighter using piezoelectric ignition
was obvious. Since the possibility of using piezoelectricity in a lighter
would have occurred to the industry, a skilled lighter manufacturer,
himself not an expert in piezoelectricity, could reasonably be expected to
seek advice from those who were. If such experts had been consulted, they
would have advised that the suggestion was definitely worth trying, and
they could have solved such problems as arose. The hypothetical skilled
man in this case was therefore a team which included persons skilled in
piezoelectricity, and not simply persons engaged in the lighter industry.
v) The skilled man should not be expected to try all combinations unless he has
a problem in mind and particular combinations might assist him in solving it;
he is not to be expected to take steps or try processes which he would not
regard as worthwhile as a possible means of achieving or assisting in practice
the objective which he has in view (see the judgment of the Court of Appeal in
Hallen Co v Brabantia (UK) Ltd [1991] RPC 195.
vi) In advanced technical fields the competent "skilled person" could be taken to
be a group of people as "skilled person" from the relevant technical branches
such as a research or production team.
vii) The person skilled in the art is normally not assumed to be aware of patent or
technical literature in a remote technical field. In appropriate circumstances,
however, the knowledge of a team consisting of persons having different areas
of expertise can be taken into account (T 141/87, T 99/89). Solutions of
general technical problems in non-specific (general) fields are considered to be
part of the general technical knowledge
This would be the case in particular if an expert in one particular field was
appropriate for solving one part of the problem, while for another part one
would need to look to another expert in a different area (T 986/96).
Thus, in real life the semiconductor expert would consult a plasma specialist if
his problem concerned providing a technical improvement to an ion-
generating plasma apparatus (T 424/90) or the average skilled person in
electronics, particularly if he did not have an adequate knowledge of
programming languages himself, might be expected to consult a computer
programmer if a publication contained sufficient indications that further details
43
of the facts described therein were to be found in a program listing attached as
an annex thereto ( 164/92 ) or in advanced laser technology, the "skilled
person" may be as a production team of three experts in physics, electronics
and chemistry respectively ( T 222/86)
viii) The average skilled person would not engage in creative thinking (T 500/91).
Yet he or she could be expected to react in a way common to all skilled
persons at any time, namely that an assumption or hypothesis about a possible
obstacle to the successful realisation of a project
Example:1
Example: 2
In T 455/91 (OJ 1995, 684) the board set out considerations on the skilled
person's likely attitude to possible changes, modifications or adjustments in
known products (eg a plasmid) or procedures (eg an experimental protocol).
Its aim was to answer, objectively and avoiding any ex post facto analysis,
the question whether it would be obvious to the skilled person to make given
changes in a structure or procedure. The skilled person in this field was well
aware that even a small structural change in a product (eg a vector, protein, or
DNA sequence) or procedure (eg a purification process) could produce
dramatic functional changes. He would therefore adopt a conservative
attitude. For example, he would neither go against an established prejudice,
nor venture into "sacrosanct" or unpredictable areas, nor take incalculable
risks. (T 441/93).
Example:3
44
c.b.When the Prior Art is incomplete and the invention lies in “Filling the
gap”, which would naturally or readily occur to the skilled person
45
b. Surprising Effect: The inventive step may be present if there is a
surprising or unexpected effect. However , if the measures which lead to
this effect ,are near at hand by themselves, a surprising effect is not
sufficient for granting a patent.
c. Long Felt Need: If the claim solves a "long felt need", there is a
presumption that a claim is not obvious as other inventors might have also
tried to solve it but could not provide the solution to fulfil the need.
e. Failure of Others: If other inventors have tried to solve a problem and
were not successful, the claim will likely involve an inventive.
g. Complexity of Work: If the work undertaken by the inventor in order to
produce the invention was particularly complex, and not readily carried
out, that is an indication that it was not a matter of routine. In such cases
the invention can be non-obvious.
i. Commercial Success: Commercial success is indicative (but not
conclusive) of an inventive step.
k. Cheaper and more economical Product and simplicity of the proposed
technological solution.
3.18 Long Standing Problem: The fact that no-one has followed a particular
path before does not of course dispose of an objection of obviousness;
otherwise any invention which was new would automatically be inventive.
However, the reasons why this has not been done before may well be
important.
Example:
In Chiron Corpn v Organon Teknika Ltd [1994] FSR 202 a claim to a
polypeptide comprising an antigenic determinant of the hepatitis C virus
was found to be non-obvious because despite the attempts of numerous
research groups over a 10 year period to identify the agent responsible for
Non-A, Non-B Hepatitis (latterly named Hepatitis C), the patentees
succeeded in a unique fashion by adopting a known technique which
would not have been obvious to try in the circumstances.
46
o.3.19 Fulfilling Need: Evidence that an invention fulfils a long-felt want
and has been commercially successful may be taken into account in
assessing obviousness (Hickman v Andrews, [1983] RPC 147 and PLG
Research Ltd v Ardon International Ltd, [1993] FSR 197), Optical Coating
Laboratory Inc. v Pilkington P.E. Ltd. [1995] RPC 145, P.166.
Example:
In Tetra Molectric Ltd v Japan Imports Ltd, [1976] RPC 547 on the other
hand, it was held that the commercial success of a cigarette lighter was
due in large part to hammer mechanisms developed since the date of the
invention; although claim 1 covered lighters which had enjoyed
commercial success, it also covered lighters which could never do so,
and no features which might ensure success were recited.
Example:
The invention was concerned with the use of particular flocculating agents in
asbestos cement manufacturing. It was held that, filtration processes being
common to many industries, two cited documents, although addressed
primarily to the mining and paper industries respectively, were likely to be read
by those concerned with the asbestos cement industry, and that such readers
would have realised that here was a newly-introduced flocculating agent
which it was well worth trying out in their filtration process [Johns-
Manville Corporations Patent, [1967] RPC 479 P 494]
47
An effect which was revealed by following the obvious course of action did
not make the action non-obvious. It was wrong to ask whether you would
have predicted the effect [Bristol-Myers Squibb Co v Baker Norton
Pharmaceuticals Inc [1999] RPC 253]
48
r.3.22 Selection: Although there is no inventive step if it is clear from the prior art
that taking that step is likely to lead to success, there may be invention if that
is only one of many courses possible, and there is no reason to infer from the
prior art that this one is more likely than the others to be profitable.
Example 1:
Example 2:
Although the size of the class from which a member or members have
been chosen is not relevant to the question of novelty of a selection
invention, it may be relevant to the question of obviousness (Du Pont de
Nemours &c (Witsiepe's) Application, [1982] FSR 303, P 310). In the Du
Pont case, the relevance of a document describing a composition with a
general formula to a claim to a particular composition falling within that
formula was considered.
49
The technical significance of the parameters by which the product or
process is selected should be considered. Where unusual parameters are used
in a claim it may be difficult to prove whether or not the prior art would
have inevitably exhibited those parameters, but in Raychem Corp.'s Patents
[1998] RPC 31 it was held that "although it may not be obvious, in the
common use of that word, to limit a claim by reference to some
particular meaningless and arbitrary parameter, that had nothing to do with
patentability. Patents are not given for skill in inventing technically
meaningless parameters." If a product or process with obviously desirable
characteristics happens to fall within the limits of such claims then they cover
what is obvious and will thus be invalid.
Example 3:
Example 4 :
50
In the case in question it was held that the common general knowledge of
the skilled person at the relevant time, along with a lack of a perceived
problem, would mean that the skilled person would never have considered
using anything other than bag technology in a vacuum cleaner. Further
examples are if persons skilled in the art would regard certain materials or
techniques as unsuitable for a particular purpose, then if the inventor has
found that this prejudice is not well-founded, then he has made an inventive
contribution to the art. Likewise the omission of a step hitherto thought to
be necessary may constitute an inventive step.
Example :
The Privy Council, upholding judgments of the New Zealand High Court
and Court of Appeal to revoke the patent for obviousness and not
involving any inventive step over what was known or used before the
priority date of the claim in New Zealand, held that “the fact that scientific
opinion might have thought that something was perfectly useless did not
mean that practising it, or having the idea of making a preparation to do
it, was an inventive step. Otherwise, anyone who adopted an obvious
method for doing something which was widely practised but which the best
scientific opinion thought was pointless could obtain a patent”.
51
expected at difficult-to-obtain pressures, and the inventor has merely taken
advantage of new techniques making such pressures more available, then that
is not inventive. Finally, if the inventor has discovered that the standard
accepted views on the low yields, while being normally true for this
reaction, are not in fact true for this particular compound, then there is
inventive step in the choice of this process.

637 (PO)).Application of M/s. Rickitt & Colman of India Ltd.
It was held that the alleged device is obvious and clearly does not involve any
inventive step. Further the opponents have not adduced any evidence
regarding grounds of patentability. So, it is construed that opponents have
dropped the aforesaid grounds. As the opposition has been successful on the
ground of section 25(l)(e), the ground 25(l)(a), i.e. wrongfully obtained need
not be discussed. Hereby the grant of patent is refused.
Example 2:
It was held that “the selection of particular range of ingredients from the
ranges already known prior art in this case cannot amount to establish the
inventive step and The variations in the amounts of the known ingredients
appear merely workshop improvements achieved by a person skilled in the art
without performing any substantial experiments and can not be said a
technical advancement of an existing knowledge which is required by the
definition of the "inventive step" as mentioned in section 2fl(ja)J of the Patents
Act, 2005.” and for the ground u/s 3(e) that
“The existence of already known characteristics of composition with known
ingredients cannot be termed as synergy among the ingredients of claimed
composition”
52
Example 3:
It was held that the ingredients recited in the principal claim have a very
specific and narrow range of proportions, which are not taught by cited
documents. Cited document do not teach how to obtain the right balance of
salt & glycerol in order to avoid a soap which is too hard or too soft. Also, in
cited documents there is no mention of balancing the quantities of glycerol or
salt against the quantities of total fatty matter. So opponents failed to establish
the grounds.
Example 4:
The claim lacks in novelty if information about anything falling within its
scope has already been disclosed in the prior art. Thus, for example if a claim
specifies alternative, or defines the invention by reference of range of values,
then the invention is not new if one of these alternatives, or if a single example
falling within this range, is already known. Thus a specific example is
sufficient to destroy the novelty of a claim when the same is defined
generically.
The grant of patent was refused on the above grounds
Example 5:
Example 6:
53
In case of Monsanto Company v. Coramandal Indag Products (P) Ltd., (1986)
(1 SCC 642: AIR 1986 712: 1986 PTC 195 SC) Herbicide CP 53619 (Butachlor)
was publicly known before Patent Number 125381 was granted. Its formula
and use had already been made known to the public by the report of the
International Rice Research Institute for the year 1968. No one claimed any
patent or any other exclusive right in Butachlor. To satisfy the requirement of
being publicly known as used in clauses (e) and (f) of section 64(1), it is not
necessary that it should be widely used to the knowledge of the consumer
public. It is sufficient if it is known to the persons who are engaged in the
pursuit of the knowledge of the patented product or process either as men of
science or men of commerce or consumers. The section of the public, who as
men or science or men of commerce, were interested in knowing about
Herbicides which would destroy weeds but not rice, must have been aware of
the discovery of Butachlor. There was no secret about the active agent
Butachlor as claimed by the plaintiffs since there was no patent for Butachlor,
as admitted by the plaintiffs. Emulsification was the well-known and common
process by which any Herbicide could be used. Neither Butachlor nor the
process of Emulsification was capable of being claimed by the plaintiffs as
their exclusive property. The solvent and the emulsifier were not secrets and
they were admittedly not secrets and they were ordinary market products. From
the beginning to the end, there was no secret and there was no invention by the
plaintiffs. The ingredients the active ingredients the solvent and the emulsifier,
were known the process was known, the product was known and the use was
known. The plaintiffs were merely camouflaging a substance whose discovery
was known throughout the world and trying to enfold it in their specification
relating to Patent Number 125381. The patent is liable to be revoked.
Example 7:
In Franz Zaver Huemer v. New Yesh Engineers, (1996 PTC (16) 164 Del.)
the court observed that the plaintiff is not an inventor of the patent device
as the device is already being used in machines for several years in
several countries especially in India vide para 9 to 16 of the affidavit, the
defendant has set out several details the machines already being
manufactured for over one and a half decade leading to an inference that
there was nothing new in the plaintiff's device. Arrangement or
rearrangement of the already known device does not amount to an
invention. As sufficient ground exist for revocation of the plaintiff's patent,
the defendant has a very good defence to the plaintiff's suit.
Example 8 :
In Surendra Lai Mahendra v. Jain Glazers [1981 PTC 112 Del ] it was held that
the plaintiff's patent is nothing more than an indigenous combination of certain
integers which form part of Morance machine designed to be less expensive
and cheaper apparatus. No doubt it may be termed as simplification
of the apparatus to some extent but it is difficult ex facie to say that it involves
an exercise of inventive step or inventive faculty. No doubt he has produced a
54
workable machine but it incorporates almost all the integers and components
of Morance machine. So it cannot be said that he has added a scintilla of
invention to produce the same. On his own showing the plaintiff had to handle
a couple of Morance machines which were not found to be workable in India
and therefore, his services had to be secured by the parties concerned as a
skilled technician to put the same in working order. It is thus no wonder that
having tried his hand on Morane machines, he was able to devise an apparatus
of his own by virtually copying the same process and making some alterations
and adjustments here and there so as to obviate the necessity of sophisticated
and costly integers used by Morance
Example 9 :
"Whenever anything inventive is done for the first time it is the result of the
addition of a new idea to the existing stock of knowledge. Sometimes, it
is the idea of using established techniques to do something which no one
had previously thought of doing. In that case the inventive idea will be
doing the new thing. Sometimes it is finding a way of doing something
which people had wanted to do but could not think how. The inventive idea
would be the way of achieving the goal. In yet other cases, many people
may have a general idea of how they might achieve a goal but not know
how to solve a particular problem which stands in their way. If someone
devises a way of solving the problem, his inventive step will be that solution,
but not the goal itself or the general method of achieving it."
Example 10 :
When the appellant has pointed out that the claim 1 is a narrower claim, the
board expressed the opinion that even if the scope of claim 1 might be narrow,
the claimed nucleic acid molecules would not appear to be anything but an
arbitrary selection, among all other possible choices, of a fragment of the
human genome encoding the Mas-related G protein-coupled receptor of one of
the cited documents, the specific fragment lacking any unexpected properties
or effects on which an inventive step could be based.
No arguments have been put forward by the appellant in this respect, except
for the allegedly novel expression pattern of the nucleic acid molecules
described in the application. However the Board notes that a possible
expression of the described molecules in erythroleukemia cells and testis,
55
which has been computationally predicted on the basis of a virtual Northern
blot and a PCR-based screening panel, does not constitute a property or an
effect on which an inventive step for the claimed nucleic acid molecules could
be based.
Therefore it was concluded that having regard to the teachings of the cited
documents the subject matter of the claims was obvious to a person skilled in
the art.
Example 11 :
It was held that the description shall be used to interpret the claims when
assessing the inventive step (T 0516/06)
In the instant case it is unambiguous from the description that TREs with a very
high level of identity fall within the definition of “different heterologous TREs”
and it was not denied that these TREs could undergo homologous
recombination. Thus, not all constructs comprised within the claim possess the
property – genomic stability – that would possibly justify acknowledging
inventive step.
In other words, the advantageous effect argued to impart inventive step is not
obtained over the scope of the claim. On claiming by the appellant that the
vectors of the prior art were unstable the Board has opined that it could only
serve to back up a conclusion of inventive step as regard the proposed solution
if the claimed subject matter entirely consisted of vectors, which had lost this
undesirable property.
For these reasons, it was concluded that the subject matter of the invention
lacks inventive step.
Example 12 :
56
unexpected technical effect, this effect must be achievable over the whole area
claimed i. e. for all products claimed. The Board felt in the instant case the
alleged technical effect has only been demonstrated for a single product,
namely the EGV of H. insolens and this effect does not serve the basis for a
acknowledging inventive step to the subject matter of claim 1 as a whole. Thus
it was opined that the alleged invention lacks an inventive step.
Example 13 :
The report of the publication states with respect to the effect of volatiles of
garlic extract and oil, neem oil and ginger (Zingiber officinale Rosc.) rhizome
extract on conidia of powdery mildew (Erysiphe polygoni DC) of pea (pleum
sativum L.).It was also stated that the extracts and oil from neem, ginger and
garlic exhibit antifungal activity. The prior publication discloses that the neem
oil is extracted by Soxhlet process. However the said document does not
disclose which solvent should be used.
Accordingly, the skilled person would use his / her general knowledge of the
isolation of natural products from plants. This commonly takes place by means
of solvent extraction and solvent elution. These are well known practices used
in all laboratories of natural products and merely imply arranging the solvents
to be used according to their solvent strength. Basically whatever the
technique chosen it is normally started with a non-polar hydrophobic solvent
as first option and then it is continued in increasing degree of polarity up to
hydrophilic solvents including water.
Since no other parameters have been discussed in the alleged invention the
extraction therefore includes Soxhlet extraction is also included. Therefore it
was decided that the alleged invention lacks inventive step and consequently
the patent was revoked.
Example 14 :
In the crucial decision T 641/00 (OJ 2003, 352) the patent in suit related to a
method in a digital mobile telephone system of the GSM type in which a
subscriber identity module (SIM card) was allocated at least two identities
which were selectively activated by the user in order to distribute the costs
between private and service calls. The board held that an invention consisting
of a mixture of technical and non-technical features and having technical
character as a whole was to be assessed with respect to the requirement of
inventive step by only taking account of those features which contributed to
that technical character. Features making no such contribution could not
support the presence of inventive step.
57
Example 15:
In Mutoh Industry Ltd's Application ([1984] RPC 35) the hearing officer
held that a drawing board employing magnetic bearings was obvious,
since it was reasonable for the drawing-board man concerned with the
problem of reducing friction to consult a bearings expert. The Patents
Court however allowed an appeal, finding that users of the known device
were not struggling to overcome a problem which inhibited their activities,
nor were manufacturers failing to put the known device on the market
because it was not sufficiently friction-free; there was therefore no
reason for the manufacturer or user to look for outside assistance.
Example 16:
In ABT Hardware Ltd's Application (BL O/36/87), the hearing officer held
the invention to be obvious. It was concerned with the use in a letter plate
of a known type of magnet comprising an elastomer loaded with ferrite
powder to hold a flap in sealing engagement with a frame over an opening in
the frame. There were specific problems associated with prior magnetic
letter plates which could arguably have led the applicants to seek specialist
advice, and the general availability and widespread use of the magnets in
question might also reasonably be expected to have led the applicants
naturally to consider their adoption in letter plates, with or without
consultation of specialists.
58
iii)iv) Methods of testing are generally regarded as capable of
industrial application if the test is applicable to the improvement or control of
a product, apparatus or process which itself is capable of industrial application.
It is therefore advisable to indicate the purpose of the test if this is not
otherwise apparent
Example 1:
It was held that the requirement that the invention can be made or used “in any
kind of industry” so as to be “capable of industrial application” carries the
connotation of trade or manufacture in its widest sense and whether or not for
profit and , further, that no industry exists in that sense to make or use that
which is useless for any known purpose [In Chiron Corp v Murex Diagnostics Ltd
and other [1996] RPC 535 (page 607)]
Example 2:
Views of the High Court of Australia in NRDC's Application, [1961] RPC 134,
give a good guide to the meaning to be attributed to industrial application. There
must be a product, but this need not be an article or substance, but must be
something in which a new and useful effect, be it creation or alteration, may be
observed. It may, for example, be a building, a tract or stratum of land, an
electrical oscillation, but it must be useful in practical affairs. A method of
eradicating weeds was held to give rise to a product (an improved crop)
because this was an artificially created state of affairs; moreover it was one
whose significance was economic.
Example 3:
Example 4:
59
applicable, even though it could be carried out by a commercial enterprise. It was
also found to be excluded as a method of doing business.
Example 5:
Example 6 :
In one of the decided cases wherein the invention is related to Novel PTP20,
PCP-2, BDP1, CLK and SIRP proteins and related products and methods it was
observed that the alleged invention discloses the description of proteins, structural
features [amino acid sequences] and their enzymatic activities. BDP1 polypeptide
is taken as example for further understanding the case herein. The amino acid
sequence for BDP1 polypeptide was given as SEQ ID NO 3 in the description and
the said polypeptide is found to be associated with tyrosine phosphatase activity.
A method and means for making it by DNA techniques is also described. A
possible role in cellular housekeeping and in certain types of cancers has been
hypothesized.
Since no industrial applicability could be derived from the description the Board
in their judgment opined that a vague and speculative indication of possible
objectives that might or might not be achievable by carrying out further research
with the tool as described is not sufficient for fulfilment of the requirement of
industrial applicability. The purpose of granting a patent is not to reserve an
unexplored field of research for an applicant.
60
CHAPTER IV
The following are not inventions within the meaning of this Act, -
(d) the mere discovery of a new form of a substance which does not result in the
enhancement of a known efficacy of that substance or the mere discovery of a
new property or new use of a known process, machine or apparatus unless
such known process results in a new product or employs at least one new
reactant.
Explanation: For the purpose of this clause, salts, easters, ethers, polymorphs,
metabolites, pure form, particle size, isomers mixtures of isomers,
complexes, combinations and other derivatives of known substance
shall be considered to be the same substance, unless they differ
significantly in properties with regard to efficacy
(g) Omitted.
(i) any process for the medicinal, surgical, curative, prophylactic [diagnostic
therapeutic] or other treatment of human beings or any process for a similar
treatment of animals to render them free of disease or to increase their
economic value or that of their products.
61
(j) plants and animals in whole or any part thereof other than micro-organisms
but including seeds, varieties and species and essentially biological
processes for production or propagation of plants and animals;
(l) a literary, dramatic, musical or artistic work or any other aesthetic creation
whatsoever including cinematographic works and television productions;
4.2 Some examples of frivolous and claims contrary to natural laws are:-For
example:
62
3(b) “An invention the primary or intended use or commercial exploitation of which
could be contrary public order or morality or which causes serious prejudice to
human, animal or plant life or health or to the environment.”
(i) The invention, the use of which is contrary to the law which is in force, or use
of which is prohibited is not patentable.
For example:
a. Any device, apparatus or machine or method for committing theft/burglary
b. Any machine or method for counterfeiting of currency notes
c. Any device or method for gambling,
d. An invention the use of which can cause injury to human beings, plants
and animals.
(iii) The invention, the present or intended use of which is likely to violate the well
accepted and settled social, cultural , legal norms of morality is not allowable
e.g method of cloning
(iv) If the invention is such that the primary or proposed use of which would
disturb the public order is not patentable e.g. A device for house-breaking,
weapons for mass-destruction,
(v) terminator gene technology
4.4.1 There is a difference between discovery and invention. A discovery adds to the
amount of human knowledge by disclosing something already existent, which
has not been seen before, whereas an invention adds to the human knowledge
by creating a new product or processes involving a technical advance as
compared to the existing knowledge.
4.4.2 A claim for discovery of scientific principle is not patentable, but such a
principle when used with process of manufacture resulting into a substance or
an article may be patentable.
4.4.3 A scientific theory is a statement about the natural world. These theories
themselves are not patentable, no matter how radical or revolutionary an insight
they may provide, since they do not result in a product or process. However, if
the theories lead to practical application in the process of manufacture of article
or substance, they may well be patentable. A claim for formulation of abstract
theory is not patentable. For example, the fact that a known material or
article is found to have a hitherto unknown property is a discovery and not
an invention. But if the discovery leads to the conclusion that the material
63
can be used for making a particular article or in a particular process, then
the article or process could be patentable.
4.4.4 Finding out that a particular known material is able to withstand mechanical
shock is a discovery and therefore not patentable, but a claim to a railway
sleeper made of the material would not fall foul of this exclusion, and would be
allowable if it passed the tests for novelty and inventive step.
Similarly, finding of a new substance or micro-organism occurring freely in nature
is a discovery and not an invention e.g. in Kirin-Amgen v Hoechst Marion
Roussel [2005] RPC 9].A DNA sequence of a gene was not an invention as
standing alone, though it was a “discovery as such”; but if it were necessary to
isolate and extract it then a process developed for this purpose could be
patentable.
4.4.7A mathematical method is one which is carried out on numbers and provides a
result in numerical form (the mathematical method or algorithm therefore
being merely an abstract concept prescribing how to operate on the
numbers) and not patentable. However, its application may well be patentable,
for example, in Vicom/Computer-related invention [1987] 1 OJEPO 14
(T208/84) the invention concerned a mathematical method for
manipulating data representing an image, leading to an enhanced digital
image.
4.4.84.4.5 Claims to a method of digitally filtering data performed on a
conventional general purpose computer were rejected, since those claims
were held to define an abstract concept not distinguished from a
mathematical method. However, claims to a method of image processing
which used the mathematical method to operate on numbers representing an
image can be allowed. The reasoning was that the image processing performed
was a technical (i.e. non-excluded) process which related to technical quality of
the image and that a claim directed to a technical process in which the method
used does not seek protection for the mathematical method as such.
Therefore the allowable claims as such went beyond a mathematical method.
4.4.94.4.6 A claim as relating to a method of analyzing samples which were
subject to chromatographic and spectrometric analysis techniques such that a
multi-variant statistical analysis technique was employed to make it easier to
identify time locations where the characteristics of samples were different. The
contribution was identified as being “A method for comparing two samples by
an analytical technique which uses chromatography and then spectrometry,
followed by a particular sequence of data analysis techniques, to give results
which enable the retention time at which the samples differ to be identified.”
[Waters Investments Limited’s Application (BL O/146/07)].It was held that the
contribution lay in t echnical field of sample analysis using chromatography
and spectrometric techniques and hence the invention was patentable
Example: Any well-established natural law like Newton’s law of gravitation is not a
patentable subject matter
3(d) The mere discovery of a new form of a known substance which does not result in
the enhancement of the known efficacy of that substance or the mere discovery
of any new property or new use for a known substance or of the mere use of a
known process, machine or apparatus unless such known process results in a
new product or employs at least one new reactant.
64
Explanation:- For the purposes of this clause, salts, esters, ethers, polymorphs,
metabolites, pure form, particle size, isomers, mixtures of isomers, complexes,
combinations and other derivatives of known substance shall be considered to
be the same substance, unless they differ significantly in properties with regard
to efficacy.
4.5.1 Mere discovery of a new form of a known substance which does not result in
the enhancement of the known efficacy of that substance is not patentable.
According to the proviso to this sub-section, a known substance in its new
form such as amorphous to crystalline or crystalline to amorphous or
hygroscopic to dried, one isomer to other isomer, metabolite, complex,
combination of plurality of forms, salts, hydrates, polymorphs, esters, ethers,
or in new particle size, shall be considered same as of known substances
unless such new forms significantly differ in the properties with regard to
efficacy. Accordingly such forms could be considered patentable provided
they significantly enhances known efficacy of that substance at the time of
filing the application.
4.5.2 In order to be patentable any salts, esters, ethers, polymorphs, metabolites,
pure form, particle size, isomers, mixtures of isomers, complexes,
combinations and other derivatives of known substance ,they must differ
significantly in the properties with regard to efficacy. The requirement here is
two fold, namely the new form must result in enhancement of known efficacy
of known substance and secondly, in order to be distinct from the known
substance, the new form must differ in the properties with regard to efficacy
4.5.3 The comparison with regard to properties or enhancement of efficacy must be
made between the known substance and the new form of known substance. In
case the new form is further converted into another new form, the comparison
must be made between the already existed form and another new form but not
between the base compound and another new form.
4.5.4 The comparison with regard to properties or enhancement of efficacy must be
made at the time of date of filing of the application or priority date in the
application is claiming the priority of any earlier application but not at the
stage of subsequent development.
4.5.5 The efficacy need not be quantified in terms of numerical value to determine
whether the product is efficacious because it is not possible to have a standard
numerical value for efficacy for all products including pharmaceutical
products.
4.5.6 In regard to ‘efficacy’ in pharmaceutical products, the Madras High Court
observed, “going by the meaning for the word “efficacy” and “therapeutic” …
…, what the patent applicant is expected to show is, how effective the new
discovery made would be in healing a disease/ having a good effect on the
body? In other words, the patent applicant is definitely aware as to what is
the “therapeutic effect” of the drug for which he had already got a patent and
what is the difference between the therapeutic effect of the patented drug and
the drug in respect of which patent is asked for.”
“Due to the advanced technology in all fields of science, it is possible to show
by giving necessary comparative details based on such science that the
discovery of a new form of a known substance had resulted in the
65
enhancement of the known efficacy of the original substance and the
derivatives so derived will not be the same substance, since the properties of
the derivatives differ significantly with regard to efficacy.” (Novartis AG Vs.
Union of India W.P. 24760/06)
4.5.7 Some of the examples of new forms are given below without limiting the
scope of the application of the provisions of the Act.
(i) Isomers:- Isomers are different compounds that have the same molecular
formula which may be broadly divided into two kinds, namely,
Example:
Cyclohexylstyrene is not considered prima facie obvious over prior art
isohexyl styrene.
66
structurally similar and provide the example of Structure –
Function linearity and may lack inventive step. However the
cases are to be decided on case to case basis.
e.g. Polymerization process using a sterically hindered amine
was held non-obvious over a similar prior art process because
the prior art disclosed a large number of unhindered amines.
(v) Metabolites:- Metabolites are the compounds that are formed inside a living
body during metabolic reaction. The types of metabolites are-
(i) Active metabolites formed from inactive precursors (e.g DOPA &
Cyclophosphamide)
(ii) Active metabolites formed from precursors that show mechanism
of action that is different from that of parent compound (e.g
Buspirone & 1-pyrimidyl piperzine Fenflouromine &
norfenfleuromine)
(iii) Active metabolites which contribute to the duration of action of the
parent compound (e.g. Hexamethylmelamine & Clobazam)
(iv) Active metabolites that show antagonistic effect on the activity of
the parent compound (e.g Trezodone & m-chlorophenyl pierzine,
Aspirin & salicylate)
67
A metabolite is not patentable since giving the drug to a patient
naturally and inevitably results in formation of that metabolite.
(vi) Prodrugs :- Prodrugs are inactive compounds that can produce an active
ingredient when metabolized in the body. Hence prodrugs and
metabolites are interlinked. When metabolyzed in the body,
inactive compounds(pro-drug) can produce a therapeutically
active ingredient,. It must be determined whether the patent on
the compound covers the prodrug and the extent to which claims
relating to certain compounds should also be allowed to include
their prodrugs. The inventive aspects of a prodrug may be
decided based on the merits of the case.
68
4.5.10 The Mere use of a known process, machine or apparatus unless such known
process results in a new product or employs at least one new reactant:- Mere
use of a known process is not patentable unless such known process results in
a new product or employs at least one new reactant. Similarly mere use of
known apparatus or machine for another purpose is also not considered
patentable
Examples 1:
"Metric time showing device" (101/Bom/72) was held not patentable. The
device comprises a normal clock or watch having usual hands for indicating
hours, minutes and seconds; wherein dial or like visual numerical indicators
are divided into 10 large divisions for hours, hours divisions are divided into
100 divisions indicating minutes and each minute is divided into 100 parts
representing seconds. It was held to be a mere use of known device and hence,
not patentable.
Examples 2:
A food-packing machine used for packing the desired amount of talcum
powder. Since this claim does not characterize any changes in the said food-
packing machine, it is presumed that the same machine has been used for the
purpose of packing talcum powder. Therefore, it is understood from the claim
that the same packing machine, which is in vogue, is used for packing the
material other than food. Hence this is also not allowable
6 Any living entity of artificial origin such as transgenic animals and plants and
any part thereof are not patentable.
69
7 The entities of artificial origin such as micro-organism, vaccines are considered
patentable.
8 The biological materials such as organs, tissues, cells, viruses etc. and process of
preparing thereof are not patentable under Section 3 (c). The biological material
such as recombinant DNA, Plasmids and processes of manufacturing thereof are
patentable provided they are produced by substantive human intervention and
functional aspects of said DNA or plasmid shall be defined.
12 Essentially biological processes for the production of plants and animals such as
method of crossing or breeding etc. are not patentable.
13 Any biological material and method of making the same which is capable of
causing serious prejudice to human, animal or plant lives or health or to the
environment including the use of those would be contrary to public order and
morality are not patentable such as terminator gene technology.
14 The processes for cloning human beings or animals, processes for modifying the
germ line, genetic identity of human beings or animals, uses of human or animal
embryos for any purpose are not patentable as they are against public order and
morality.
70
claimed which was later amended to a process for the preparation of novel
composition containing imidazole salicylate having formula 1 shown in the
accompanying drawings, as the active principle of antipholgistic, antipyretic
and analgesic products,. The invention was characterized in that a product is
previously obtained by reacting, mole by mole, acetylsalicylic acid with
imidazole in an inert organic solvent and that, using the solid product obtained
in the reaction after purification by recrystalization lation, homogenous
composition were are produced with pharmaceutically acceptable vehicles
suitable for oral, parental or topic administration.
It was held by the Controller that the active compound such as imidazole
salicylate is known in the art and applicant could not develop any special
property or even improve upon the property of the compound to be mixed up
with the usual carrier to form the composition. Further more, the description
contained s no indication of using any special type of solvent for its
purification by re-crystallization and, therefore, the invention was is not
patentable under section 3(d) of the Act.
4.5.13 In the application for patent no. 134883, dated 08.03.1972, a method of
control of post-embryonic development stages of coleoptera and Diptera
inhabiting in the soil was claimed. The invention was , characterized by
applying to said soil a toxic amount of a compound selected from the group
consisting of o,o-diethyl S-(tert butylthio) methyl phosphorodithuoate and o.o-
diethyl S-[(1,,1-dimethypropyl)thio]methyl phosphorodithicate.
was claimedIt which was amended to a method for preparing a long effective
pasticical preparation useful in the control of the postembryonic stages of
coleoptera and Ddiptera inhabiting the soil having an long residual of
paesticidal activity and un-objectionable odour which compriseds treating (i)
sorptive or non -sorptive granular particles of a material like di-atomite or
silicas with 5% to 25% of o,o-diethyl 3-(tert-butylthio) methyl phospho-
rodithicate and when preferred (a) applying a super coating of an inert material
like clay or talc on the treated granular non-sorptive material or (b) applying a
deactivator to the surface of the sorptive material before treating with the said
phosphorodithicate, using one or more conventional solvents.
It was held by the Controller that materials and solvent specified in the claim
were are conventional and customary application ors well known in the
pesticidal art. Further, the method for preparation of the formulation was are
conventional methods and gave iven a pestisicidally active compound, which
every person skilled in the pesticidal art would ill have to make as a
71
formulation by applying active compound by conventionasl metjhod to the
conventional applicators for using the ppesticidal active compound.
Accordingly, a method of making a formulation by applying a conventional
method a pesticidal compound to a conventional applicator is only steps in the
use of compound or substance for treting the patient. Therefore invention falls
within section 3(d) as the mere non substance or non compound.
4.5.14
In case of M/s. Astra Aktiebolag [Patent Application No. 1354/del/1998], the
controller in his decision dated 12th June 2007, held that the patent application
is not patentable under section 3(d) of the Patent Act 1970, as “present
pharmaceutical formulation is a selection from the prior art formulation due to
the specific selection of HPMC of cloud point above 45.6° C having similar
medicinal use and with the same therapeutic efficacy… the benefit claimed by
the applicant in the present application is not accruable to the user in terms of
therapeutic quality of the product but to the manufacturer only in terms of
consistency in the production of formulation…”.
4.5.15 In patent application No. 1577/DEL/1996 was refused inter alia under the
provisions of section 3(d) of the Patents Act, 1970. The controller in his
decision dated 12th June 2007 held that “the present invention provides a new
form of known substance either in anhydrous or hydrated form III of
Atorvastatine having same therapeutic activity and in the same field. It only
claims some improvement in physical property, which does not make any
change in therapeutic efficacy of the compound as compared to the prior art
compound. Therefore this new form does not qualify the requirement under
section 3(d).”
4.6.1 Invention not patentable under section 3 (d) &(e) (to be also incorporated in (e)
:- In a patent application no. 782/Cal/l981, dated 13.07.1981, an invention
related to pharmaceutical composition exhibiting anti-phlogistic, antipyretic and
analgesic activity and high gastroenteric tolerance in unit doses form which
contains imidazol salicylate as the active ingredient in the amount of 100-600
mg and an inert carrier was claimed which was later amended to a process for
the preparation of novel composition containing imidazole salicylate having
formula 1, as the active principle . The invention was characterized in that a
product is previously obtained by reacting, mole by mole, acetylsalicylic acid
with imidazole in an inert organic solvent and that, using the solid product
obtained in the reaction after purification by recrystalization , homogenous
composition were produced with pharmaceutically acceptable vehicles suitable
for oral, parental or topic administration.
It was held by the Controller that the active compound such as imidazole
salicylate is known in the art and applicant could not develop any special
property or even improve upon the property of the compound to be mixed up
with the usual carrier to form the composition. Furthermore, the description
72
contained no indication of using any special type of solvent for its purification
by re-crystallization and, therefore, the invention was not patentable under
section 3(d) of the Act.
4.6.14.6.2 A mixture of sugar and some colorants in water to produce a soft drink
is a mere admixture resulting into aggregation of the properties. Similarly a
mixture of different types of medicament or medicine to cure multiple diseases
is also a mere admixture of substances and is not a patentable invention.
4.6.24.6.3 However, an admixture resulting into synergistic properties of a
mixture is not considered as mere admixture e.g. soap, detergent, lubricants
and polymer composition etc. Hence they are patentable.
4.6.34.6.4 A process for producing a substance by admixing, which is resulting
into the aggregation of the properties of the components thereof, is also not
patentable invention.
4.6.44.6.5 In assessing the inventive step involved in an invention based on a
combination of features, consideration must be given to whether or not the
state of the art was such as to suggest to a skilled person precisely the
combination of features claimed. The fact that an individual feature or a
number of features were known does not conclusively show the obviousness
of a combination.
4.6.54.6.6 A mere aggregation of features must be distinguished from a
combination invention. The existence of a combination invention requires that
the relationship between the features or groups of features be one of functional
reciprocity or that they show a combinative effect beyond the sum of their
individual effects. The features should be functionally linked together which
was the actual characteristic of a combination invention.
4.6.64.6.7 An anti-perspirant composition for application to human skin
(63/Bom/75) was held not patentable.
4.6.74.6.8 A composition comprises of non-cellulosic moisture absorbing
polymer capable of absorbing moisture at least equivalent to its weight and a
carrier. The composition was held as mere admixture, for the reason that it has
got total sum of the properties of two components, namely, the properties of
absorbent polymer to absorb moisture or to absorb perspiration on being
applied to human skin, which has not been in any way influenced by the
presence of said carrier to act as carrier or diluents.
4.6.84.6.9 A composition of two drugs, i.e. Paracetamol and Ibuprofen for curing
fever and pain or process of preparation thereof is not patentable for the
reason that the composition is a mere admixture of two drug components
resulting into aggregation of properties thereof; since Paracetamol is well
known for treatment of fever and Ibuprofen for treatment of pain.
4.6.94.6.10 However, if the mixture of drugs exhibits some unexpected results or
synergistic properties in their action , then such composition is considered as
patentable subject matter.
73
4.6.104.6.11 In general all the substances which are produced by mere admixing, or
a process of producing such substances should satisfy the requirements of
synergistic effect in order to be patentable. The synergistic effect should be
clearly brought out in the description and examples by way of comparison at
the time of filing of the application and should be stressed in the principal
claim.
4.6.114.6.12 In the matter of an application for Patent No. 63/Bom/75 Decisions on
patents and designs, vol.1, published by The Patent Office Technical Society
p.17, Hindustan Lever Limited, Applied for Patent for an invention relating to
an antiperspirant composition. It was held by the Controller that an admixture
having only the aggregation of the individual properties of the components
thereof is not an invention within the meaning of the Act and is thus not
patentable, A process for producing such an admixture is also not patentable.
In case the presence of one or more components of the composition influence
the properties of the other components of the composition with the result that
the ultimate properties of the composition would be different from the
aggregation of the individual properties of the components thereof, such an
admixture would be patentable under the Patents Act, 1970.[Page 26, point 10]
74
device comprising a water level, tilt meter and crack-width meter measuring
means, all three well known in the art prior to this application and working
independently of one another in a known manner with no modifications in
their functioning.
4.7.4 A mere juxtaposition of known devices in which each device functions
independently is not patentable. It is accepted as sound law that mere placing
side-by-side old integers so that each performs its own function independently
of the others is not a patentable combination (British Celanese Ltd. vs
Courtaulds Ltd (52) RFC 171), e.g. a floor mill provided with sieving
means.However, where the old integers when placed together have some
working interrelation, producing a new or improved results, then there is a
patentable subject matter in the working interrelation brought about by the
collection of the integers.
4.7.5 A mere juxtaposition of features, already known before the priority date,
which have been chosen arbitrarily from amongst a number of a different
combinations, which could be chosen, is not a patentable invention.
4.7.6 Further, when two or more features of an apparatus or device are known, and
they are juxtaposed without any inter dependence on their functioning of the
apparatus or device, they should be held to have been already known
(Rampratap vs. Bhabha Atomic Research Center, 1976 IPLR 28 P. 35)]. e.g.,
an umbrella with fan(388/Bom/73), Bucket fitted with torch, Clock and
transistor in a single cabinet. These are not patentable subject matter , since
they are nothing but mere arrangement and rearrangement of items without
having any working interrelationship between them and functioning
independently of each other.
4.7.7 Another example is of a play-cum-educational device (1532/Cal/76). The
device comprises of a chart, a set of tokens for players and one or more dice. It
was held not patentable under the provisions of this section since the chart,
token and dice, all are working independently of each other and there is no
interrelation between them.
4.7.8 In case of the Franz Zaver Huemer v. New Yesh Engineers, (1996 PTC (16)
164 Del. ) it is held that the plaintiff can not claim the to be an inventor of the
patent device as the device is already being used in machines for several
years in several countries especially in India vide para 9 to 16 of the affidavit,
the defendant has set out several details of the machines already being
manufactured for over one and a half decade leading to an inference that there
was nothing new in the plaintiff's device. Arrangement or rearrangement of the
already known device does not amount to an invention. As sufficient ground
exists for revocation of the plaintiff's patent, the defendant has a very good
defence to the plaintiff's suit.
4.7.9 In case of 1985 (5) PTC 71 (Del) , the application for grant of patent was in respect
of apparatus for producing metallic bellows. During the opposition
proceedings it was held that both hydraulic machine and roll forming
machine are undoubtedly the separate machines functioning independently of
other there being no novel feature stated by the applicant. Hence, the ground that
there is no invention is accepted as the applicant is seeking the patent right on
known types of hydraulic forming and roll forming machines which is not allowable.
4.7.10 In the matter of an application made by Figurette and Cosmetics Private
Limited (Applicant) for application No. 388/Bom/73. dated 28 Nov’73 filed
for an invention entitled “Improvements in or relating to umbrellas or Parasols
and the like fitted with cooling devices” and the complete specification relates
75
to umbrellas or parasols which provides ventilation and circulation of air in
addition to providing protection to rain or sum, and the claims were mainly
objected to “section 3(f) of The Patent Act, 1970.The principal claim read as
“An umbrella, parasol and the like, comprising an electric motor having a fan
propeller fitted on its shaft and housed at the top of the umbrella, parasol,
arranged to blow air downwardly and an electric current supply means for the
said electric motor”. The applicant argued that the interrelation between the
two known devices is that the electric motor is mounted at the upper end of the
central rod of the umbrella and that the electric motor cannot start functioning
unless the umbrella is opened. The Controller held that it can be seen from the
drawings accompanying the complete specification, the housing in which the
electric motor is located is above the cloth covering the umbrella and thus
would function irrespective of the fact whether the umbrella is in opened or
closed condition. Moreover, simply mounting the electric motor at the central
rod of the umbrella merely amounts to an inter-relation as regards to the
placing of known devices and does not amount to an interrelation as regards to
the functioning of the known devices… … … accordingly, I am of the opinion
that both the known devices in the applicants invention namely the umbrella
and the electric motor function independently of each other in their usual
known way and as such there is no interrelation in their functioning and the
invention falls within the purview of section 3(f) of Patent Act and thus not
Patentable. (Para 11 Page 79, 80, 81).
4.7.124.7.11 A new combination may be the subject matter of a patent although
every part of the combination, per se, is old for here the new article is not the
parts themselves but the assembling and working of the parts, together.
(Lallubhai Chakkubhai vs. Shamaldas Sankalchand Shah, A.I.R 1934 Bom.
407).
4.7.134.7.12 The merit of a new combination very much depends upon the result
produced. Where a slight alteration turns that which was practically useless
intowhat is useful and important, it is fit subject matter for a patent ((Lallubhai
Chakkubhai vs. Shamaldas Sankalchand Shah, A.I.R 1934 Bom. 407).
3(i) Any process for the medicinal, surgical, curative, prophylactic, diagnostic
therapeutic or other treatment of human beings or any process for a similar
treatment of animals to render them free of disease or to increase their
economic value or that of their products.
76
4.9.1 A method of treatment of malignant tumour cells and method of removal of
dental plaque and carries are not patentable, since they are held as treatment of
human beings. Also, treatment of sheep for increasing wool yield (1958 RPC
85) was held as not patentable.
4.9.2 An invention of a method of treatment of the human or animal body by
surgery or therapy or of diagnosis practised on the human or animal body shall
not be taken to be capable of industrial application.
4.9.3 The art of curing illness cannot be said to be patentable.
4.9.4 The term “therapy’’ includes prevention as well as treatment or cure of
disease. Therefore, the process relating to therapy is also not patentable as held
in Unilever Limited (Davis') Application, [1983] RPC 219
4.9.5 Although some medical dictionaries pointed towards a narrow interpretation
of the term, other works of reference, including non-specialist dictionaries,
indicated a more general meaning; this was preferred in this case,
following the principle that words in statutes dealing with matters relating
to the general public are presumed to be used in their popular, rather than
their narrowly legal or technical, sense. However, for a treatment to
constitute therapy, there must be a direct link between the treatment and
disease state being cured, prevented or alleviated, (BL O/248/04).
4.9.6 It appears that any medical treatment of a disease, ailment, injury or disability, i.e.
anything that is wrong with a patient and for which he would consult a doctor,
as well as prophylactic treatments such as vaccination and inoculation, is to be regarded as
therapy. The same considerations apply for animals as for human patients, so
that for example prophylaxis and immunotherapy in animals are regarded as
therapy[T 24/91]
4.9.7 In Ciba-Geigy AG's Application (BL O/30/85), a method of controlling
parasitic helminths (worms which may develop in the animal body, for
example, in the intestinal tract of animals such as sheep) by the use of a particular
(novel and inventive) anthelmintic composition was held non patentable as
s u c h a n i n f e s t a t i o n w a s a d i s e a s e r e q u i r i n g me d i c a l treatment of
the animal and that such treatment, whether curative or preventative,
constituted therapy practised on the animal body.
4.9.8 Prophylactic treatment, aimed at maintaining health by preventing ill effects
that would otherwise arise, amounts to a method for treatment by therapy Both
prophylactic and curative methods of treating disease are covered by the word
therapy, since both are directed to the maintenance or restoration of health The
same consideration applies for animals as well as for human beings. For
example prophylatic immuno-therapy in animals are regarded as therapy.
4.9.9 An application of substance to human body purely for cosmetic purposes is
not a treatment or therapy. On the other hand, the application to the skin of an
ointment designed to be effective to remove keratoges from the skin would be
the instance of medical treatment. Here, “Treatment” in relevant senses means
that the purpose of application of a process or substance to the body must be
to arrest or cure of a disease or diseased condition or correcting some
malfunction or amelioration of some incapacity or disability (Joos Vs.
Commissioner of Patent (1973) RPC 59).
4.9.10 Application of substances to the body for purely cosmetic purposes is not
therapy. In allowing claims to a process for improving the strength and
elasticity of human hair and finger nails, the High Court of Australia
observed that, while a process for the treatment of the human body as a
means of curing or preventing a disease or other disorder was not patentable,
77
"Those who apply chemical preparations to the skin to prevent sunburn in
climates which enjoy sunshine and moderate air temperatures can scarcely be
regarded either as, in a relevant sense, treating their bodies or as undergoing
treatment. On the other hand, the application to the skin of an ointment
designed and effective to remove keratoges from the skin would be an
instance of medical treatment. To be treatment in the relevant sense, it
seems to me that the purpose of the application to the body whether of a
substance or a process must be the arrest or cure of a disease or diseased
condition or the correction of some malfunction or the amelioration of
some incapacity or disability" (Joos v Commissioner of Patents, [1973]
RPC 59).
4.9.11 It was held in Lee Pharmaceuticals application [(1978) RPC 51] that, since,
one of the reasons of grinding pits and fissures in teeth was to prevent the
onset of dental decay, the purpose of the treatment was therapeutic rather than
cosmetic.
4.9.12 Patent, may however be obtained for surgical, therapeutic or diagnostic
instrument or apparatus. Also the manufacture of prostheses or artificial
limbs and taking measurements therefor on the human body are
patentable.
4.9.13 The claims to a method of removing dental plaque and / or caries were refused
in Oral Health Products Inc (Habtead's Application, (1977) RPC 612), as the
claim was to a method of cleaning teeth, which embraced both curative and
cosmetic effects.
4.9.14 This decision has been followed in another case, where a claim was refused to
a method of cleaning teeth which removed both plaque and stains. It was
argued that, when applied to perfectly healthy teeth, the method was purely
cosmetic. But the hearing officer observed that practically all medical
treatments which are preventive in nature (such as vaccination) must, at times,
be applied to people who would have remained healthy anyway, but they
remained medical treatments
4.9.15 In Oral Health Products Inc (Halstead's) Application, [1977] RPC 612,
claims to a method of removing dental plaque and/or caries were refused, as
was a claim to a method of cleaning teeth which embraced both curative
and cosmetic effects. This decision has been followed under the 1977 Act
in ICI Ltd's Application No 7827383 (BL O/73/82), where a claim was
refused to a method of cleaning teeth which removed both plaque and
stains; it was argued that when applied to perfectly healthy teeth the method
was purely cosmetic, but the hearing officer observed that practically all
medical treatments which are preventative in nature (such as vaccination)
must at times be applied to people who would have remained healthy
anyway, but they remained medical treatments
4.9.16 In T 290/86 the Board held that the use of a lanthanum-containing
composition for cleaning plaque and/or stains from human teeth...will always
inevitably have a therapeutic effect (at least in the prophylactic sense) as well
as a cosmetic effect. Thus the invention as here claimed is not directed solely
to a cosmetic effect, but is also necessarily defining a treatment of the human
body by therapy and hence excluded from patentability.
4.9.17 Methods of treatment of the human or animal body by surgery are excluded.
‘Surgery’ is defined as the treatment of disease or injury by operation or
manipulation. It is not limited to cutting the body but includes manipulation
such as the setting of broken bones or relocating dislocated joints (sometimes
78
called "closed surgery"), and also dental surgery. In general, any operation on
the body, which required the skill and knowledge of a surgeon, would be
regarded as surgery and includes non-curative treatments such as cosmetic
treatment, the termination of pregnancy, castration, sterilization, artificial
insemination, embryo transplants, treatments for experimental and research
purposes and the removal of organs, skin or bone marrow from a living donor
are, if carried out by surgery, regarded as surgical treatments. Once it has
been decided that a method constitutes surgery, therapy or diagnosis
practised on the human or animal body, it is necessarily non-patentable.
For example, methods of abortion, induction of labour, control of
oestrus or menstrual regulation are always therapy, irrespective of the
reason for the treatment.
4.9.18 In Unilever Limited (Davis1) Application, [1983] RPC 219, it was observed
that any method of surgical treatment, whether curative, prophylactic or
cosmetic, is not patentable. This view was upheld in an another case also,
while refusing to allow claims to a method of implanting an embryo
transplant from a donor mammal into the uterus of a recipient mammal, since
the method would necessarily have to be carried out by a surgeon or veterinary
surgeon.
4.9.19 Methods of diagnosis practiced on the human or animal body are excluded.
Methods of diagnosis performed on tissues or fluids, which have been
permanently removed from the body are, therefore, not excluded from
patentability.
4.9.20 Diagnosis is the identification of the nature of a medical illness, usually by
investigating its history and symptoms and by applying tests.
Determination of the general physical state of an individual (e.g. a fitness
test) is not considered to be diagnostic if it is not intended to identify or
uncover a pathology. Section relates to methods of diagnosis practised on
the human or animal body; diagnosis in itself is a method of
performing a mental act and is excluded from patentability. Typically, the
process of diagnosis involves a number of steps leading towards
identification of a condition. For a claim to fall under this prohibition, it
must include both the deductive step of making the diagnosis and preceding
steps constructive for making that diagnosis involving specific interactions
of a technical nature with the human or animal body. The exclusion is
therefore a narrow one, and also requires all the method steps of a technical
nature to be practised on the body. In determining whether or not a
method is a diagnostic, the Board held that it is irrelevant whether it is
necessary for a medical or veterinary practitioner to be involved.
Furthermore, a method is “practised on the human or animal body” if
it involves any interaction which necessitates the presence of the patient, so
will include both invasive and non-invasive methods. Methods of diagnosis
performed on tissues or fluids which have been permanently removed from
the body are not excluded. "Body" should be taken to mean living body,
and a method practised on a dead body, for example in order to determine
the cause of death, would not be exclude.
4.9.21 Methods of therapy carried out on materials temporarily removed from the
body, for example, when blood is circulated through an apparatus while
remaining in living communication with the body, are not patentable (cf
Calmic Engineering Co Ltd's Application, [1973] RPC 684).
79
4.9.22 In Ciba-Geigy AG's Application , the objection was raised to certain claims for
a method of controlling parasitic helminthes (worms which may develop in the
animal body, for example, in the intestinal tract of animals such as sheep) by
the use of a particular (novel and inventive) antihelmintic composition, The
applicants contended that the composition when administered to an animal
would prevent the reproduction of the helminthes and kill them should they
infest the animal, but without affecting the animal's body, and that its use was
therefore not "therapy". However, the applicants' specification made it clear
that an infestation of helminthes worms can result in restricted growth,
damage to the animals and even death, if not properly treated. Moreover, the
application made no mention of controlling helminthes by the use of the
composition in any environment other than the animal body. The hearing
officer considered that such an infestation was therefore a disease requiring
medical treatment of the animal and that such treatment, whether curative or
preventative, constituted therapy practiced on the animal body and
consequently held that the claims in question were not allowable.
4.9.23 In G 1/04 (OJ 2006, 334) the Enlarged Board of Appeal held that whilst the
legislator had chosen the legal fiction of lack of industrial applicability, the
exclusion from patentability of the above-mentioned methods under Art. 52(4)
EPC seemed actually to be based on socio-ethical and public health
considerations. Medical and veterinary practitioners should be free to take the
action they considered suited to diagnosing illnesses by means of investigative
methods. Consequently, the policy behind the legal fiction referred to above
appeared to be aimed at ensuring that those who carry out diagnostic methods
as part of the medical treatment of humans or veterinary treatment of animals
were not inhibited by patents (see T 116/85).
4.9.24 In case of M/s. A G A Medical Corporation, USA [Patent Application
No.1283/DEL/2004], the controller held that “The purpose of the invention is
to provide a method for determining the nominal or stretched diameter of an
internal opening or defect with in a patient and particularly determining the
stretched diameter of a septal defect within the heart of a patient is inseparably
connected with the method of treatment” and therefore it is not patentable
under section 3(i) of the Patent Act 1970.
4.9.25 In an application no 1377/DEL/1999 the claimed invention was related to a
method for in vitro production of isolated langerhans islets endocrine cells free
from fibroblasts so as to be suitable for transplantation. The process discloses
the steps of culturing and proliferating the cells and back and forth aspiration
to separate fibroblast from the cells, which will be capable of differentiating
into insulin producing cells.The applicant argued that (1)the process is novel
and has utility as fibroblast free langerhans islets are useful in the enhanced
production of insulin. to control diabetes,(2)Kolkata High Court has already
allowed patenting of a substance containing living organisms and(3)Indian
Patent law does not bar the grant patent for such invention. However the
Controller refused the application under section 15 on the grounds that the
invention claimed is not patentable under section 3(i) as a method of treatment
of human being, since langerhans islets are freshly taken from the body of
patient in order to treat them to remove fibroblast so as to increase secretion of
insulin. The end product of the process is nothing but a cluster of cells or piece
of tissues of human body. The principles laid down in Kolkata High Court are
not applicable as the end product of the process of present invention is not
80
commercial entity and cannot be passed on from one person to another upon
the transaction of purchase or sale.
3(j) Plants and animals in whole or any part thereof other than micro-organisms but
including seeds, varieties and species and essentially biological processes for
production or propagation of plants and animals
4.10.1 As per this sub-section, while plants and animals, or any part of the plant or
animal is not patentable, an exception is made in the case of micro-organisms.
However, any discovered micro-organism from the nature is not patentable.
4.10.2 In Dimminaco – A.G vs. Controller of Patents & Designs and others (AID
No.1 of 2001)the issue involved was the patenting of the process for
preparation of infectious bursitis vaccine, which is invented for protecting
poultry against infectious bursitis. The Controller held that the process of
separation of the vaccine which has living entity cannot be considered a
manufacture and hence not patentable under section 2(1)(j)of the Patents Act.
He also held that since the vaccine contains living organism it cannot be
patented. The court held that the matter involved is of a new process of
preparation of vaccine under specific scientific conditions and the said vaccine
is useful for protecting poultry against contagious bursitis infection and there
is no statuary bar to accept a manner of manufacture as a patentable even if the
end products contain living organism.
4.10.3 Plant varieties are provided protection in India under the provisions of the
Protection of Plant Varieties and Farmers’ Rights Act, 2002.
81
Therefore the allowable claims as such went beyond a mathematical method.
3(l) A literary, dramatic, musical or artistic work or any other aesthetic creation
whatsoever including cinematographic works and television productions;
4.12.1 Writings, music, works of fine arts, paintings, sculptures, computer programs,
electronic databases, books, pamphlets, lectures, addresses, sermons, dramatic-
musical works, choreographic works, cinematographic works, drawing,
architecture, engraving, lithography, photographic works, applied art, illustrations,
maps, plans, sketches, three-dimensional works relating to geography, topography,
translations, adaptations, arrangements of music, multimedia productions, etc. are
not patentable. Such works fall within the domain of the Copyright Act, 1957.
3(m) Schemes, rules and methods for performing mental acts, playing games
82
Placement of content in the manual as decided on 22.01.2008/ as
explanation/ as example
1..[May be attached to the interpretation of Section 3]
a) Isomers
Isomers are different compounds that have the same molecular formula which may
be broadly divided into two kinds, namely,
Isomers having the same empirical formula but having structural differences may
be considered novel and may not normally offend “obviousness” as they are
structurally different.
83
Example: Cyclohexylstyrene is not considered prima facie obvious over prior art
isohexyl styrene.
Once a compound having a chiral center is known, its enantiomers are obvious
because a person skilled in the art knows that a compound having a chiral center
exists in two optically active forms. Hence, a product patent may not be granted
for the enantiomer form. However, when a new compound is claimed having
chiral center(s) for the first time, a product patent may be granted.
c) Homologues
Homologues normally display add-on property. They are structurally similar and
provide the example of Structure – Function linearity and may lack inventive step.
However the cases are to be decided on case to case basis.
e.g. Polymerization process using a sterically hindered amine was held non-
obvious over a similar prior art process because the prior art disclosed a large
number of unhindered amines.
Another interesting example is that prior art structures do not have to be true
homologs or isomers to render structurally similar compounds prima facie
obvious.
e.g. Claims and Prior art were for heterocyclic carbamoyloxmino compounds
having pesticidal activity. The only structural difference was that the ring
structures of the claimed compounds had two carbon atoms between two sulphur
atoms whereas the prior art ring structures had either one or three carbon atoms
between two sulphur atoms. The court held that although the prior art compounds
were not true homologs or isomers of the claimed compounds, the similarity
between the chemical structures and properties is sufficiently close that one of
ordinary skill in the art would have been motivated to make the claimed
compounds in searching for new pesticides.
d) Polymorphs
Some compounds are present in polymorphic forms, i.e., they crystallize in diverse
forms. Such forms can be deemed within the prior art and therefore not patentable.
However, process patent may be allowed for the new polymorph, if the polymorph
is prepared by a novel process involving inventive step.
84
patentable if they were inevitably obtained following the process of the basic
patent on the active ingredient or if they were covered by a previous product
patent.
e) Metabolites:
Metabolites are the compounds that are formed inside a living body during
metabolic reaction. The types of metabolites are-
A metabolite is not patentable since giving the drug to a patient naturally and
inevitably results in formation of that metabolite.
f) Prodrugs :
Prodrugs are inactive compounds that can produce an active ingredient when
metabolized in the body. Hence prodrugs and metabolites are interlinked. When
metabolyzed in the body, inactive compounds(pro-drug) can produce a
therapeutically active ingredient,. It must be determined whether the patent on the
compound covers the prodrug and the extent to which claims relating to certain
compounds should also be allowed to include their prodrugs. The inventive
aspects of a prodrug may be decided based on the merits of the case.
Hydrates, acid addition salts and other derivatives, which are routinely prepared,
prima facie lack an inventive step. However, where there is a problem like
stability, absorption etc., and there is a long standing problem in preparing the
derivatives, patentability of such process may be considered.
h ) Purification Compounds:
Mere purification of known material does not result in the patentable subject
matter due to lack of novelty and inventive step.
i) Pharmaceutical Compostions

t.The pharmaceutical compositions, other than mere admixtures resulting in the

CHAPTER III V
Section 6.
Persons entitled to apply for patents;
(a) by any person claiming to be the true and first inventor of the
invention;
(b) by any person being the assignee of the person claiming to be the true
and first inventor in respect of the right to make such an application;
(b)(c) by the legal representative of any deceased person who immediately
before his death was entitled to make such an application.
(2) An application under sub-section (1) may be made by any of the persons referred
to therein either alone or jointly with any other person.
Section 2(1) (y ) "true and first inventor" does not include either the first importer of
an invention into India, or a person to whom an invention is first
communicated from outside India.
5.1.1 EXPLANATION
95
ii) The term "person" as defined in the Patents Act includes
Government. [Section 2(1)(s)]
iii) The term “person” also defined in the General Clauses Act 1897 include
any company or association or body of individual, whether incorporated or
not unalthough in such cases but not a firm, partnership or body
which is unincorporate, individualIn the case of a limited partnership,
the application may be in the names of all personally responsible partners
(see also 7.05)
iii)iv) True and first Inventor does not include either the first importer of an
invention into India or a person to whom an invention is first communicated
from outside India (S. 2(1)(y)). The applicant is required to disclose the
name, address and nationality of the true and first inventor.
iv)v) Assignee can be a natural person or other than natural person like
registered company, research organization, educational institute or
Government (S.2 (1)(s)).
v)vi) Assignee includes assignee of the assignee also (S. 2(1)(ab)).
vi)vii) ‘Proof of right’ to apply such as assignment deed should be submitted by
the assignee. Proof of Right is required even when the applicant in
convention country/ PCT international application is the same as that in
India.
Legal representative means a person who in law represents the estate of a
deceased person (S.2 (1)(k)). In such a case, they person should file death
certificate alongwith other appropriate legal instruments etc. as proof of
right. The applicant shall be a national of India or any other country
which is not notified by Government of India as countries not providing
for reciprocity,
viii)
ix) Convention country means any country, which is a signatory or party, or
group of countries or union of countries or intergovernmental organizations
which are signatories or parties to an international, regional or bi-lateral
treaty, convention or arrangement, of which India is also a party. A
convention country/countries for the purpose of the Act (S 133), is one
which accords the same rights in respect of the grant of patents and
protection of patent rights to citizens of India, as it accords to its own
nationals. (S.133 & S.134).
5.1.2 It was held that a firm can apply for a patent as assignee; Shinning
Industries v. Shri Krishna Industries, AIR 1975 All 231.
5.1.3 In case of the Dyer Meakin Breweries Ltd. V Scotch Whisky Association,
(AIR 1980 Del 125.), it was held that Section 68 of the Act provides that the
Assignment Deed, when registered, shall have effect from the date of its
execution. It is, therefore, apparent that as soon as the entry of registration of his
deed was made by the Patent Office on 21st June 1979 the plaintiff became the
assignee of the patent in question with effect from the date of execution of the
deed i.e. 22nd May 1979. Section 68 of the Act provides that the assignment of
96
a patent shall not be valid unless the same were in writing and the agreement
between the parties concerned is reduced to the form of a document embodying
all the terms and conditions governing their rights and obligations and
the application for registration of such deed is filed with the Controller within
six months of the execution of the document. Section 68 of the Act has thus
been compiled with.
5.1.4 In the matter of an application for patent no. 551/Del/78, 1DPD, 39, the
Controller held that the expression “without prejudice to provisions contained in
Section 6” should be interpreted only as to mean without detriment to the
applicant’s right to file an ordinary application”.
Rule 5:

is given , the Controller shall be under no obligation either to proceed or deal
with any proceeding, or patent or to send any notice that may be required to
be given under the Act or these rules and the Controller may take suo motu
decision in the matter.
EXPLANATION
97
i) Application for the patent has to be filed in the respective patent office as
mentioned below where the territorial jurisdiction is decided based on whether any
of the following occurrence falls within the territory
ii) A foreign applicant shall give an address for service in India and the jurisdiction
will be accordingly decided. An Indian applicant also can give his Patent Agent’s
address as address for serving documents if he/she wishes to do so.
98

petition for such condonation of delay is made by the party to the
Controller immediately after the receipt of the document or a
communication along with a statement regarding the circumstances of
the fact and evidence in support of the statement:
Provided that the delay condoned by the Controller shall not exceed the
period between the date on which the party was supposed to have received
the document or communication by ordinary course of mail or
electronic transmission and the actual date of receipt of the same.
5.2.4 Whether “Any other person under the Act” under the ambit of rule 6 include the
“Patent Agent” apart from the Controller and the Patent Office when read with
Section 2(1)(s). The Controller held that the expression “any other person under the
Act or Rules” in rule 6 would mean that whenever there is a bi-party or multi-party
proceedings viz. an opposition under section 25, 61, or 92 of the Act, the parties to the
proceedings are required to serve certain documents such as statements and evidence
on each other, under intimation to the Controller and also on the Controller. In the
course of any of the said proceedings if any document has been sent by one party to
the other party and to the Controller by post sufficiently in advance, then if there is a
postal delay as a result of which the other party or the Controller receives the said
documents late, the delay involved will be condoned by the Controller under Rule 6
and the documents will be taken on record and deemed to have been received on the
due date……………………………. Accordingly, I cannot accept …………….with
regard to the expression “any other person under the Act or the Rules” as including
Patent agent to whom his client has send the documents.

Section 135.
Convention Applications;
108
the said inventions, and the requirements of clause (b) of sub-section (1) of
section 136 shall, in the case of any such application, apply separately to
the applications for protection in respect of each of the said inventions.
(3) In case of an application filed under the Patent Cooperation Treaty
designating India and claiming priority from a previously filed
application in India, the provisions of sub-sections (1) and (2) shall apply
as if the previously filed application were the basic application:
Provided that a request for examination under section 11B shall be made
only for one of the applications filed in India.
5.2.6 In the matter of a petition made under rule 6 of The Patent Rules filed by
International Chemical Company Limited (Applicant) for application No. 912/Cal/81
the Controller held that “ when the provisions of any statute are definite and clear cut ,
the question of applying principles of natural justice does not arise. Under Section 135
of the Act a Convention application has to be made within 12 months from the date of
the basic application. So it is the duty of the applicants to take care of all eventualities
and see that their Convention applications are filed within the period stipulated in
Section 135 of the Act.' In fact' Section 135 provides ample time to the applicants to
guard against almost any eventuality. Hence the principle of natural justice cannot be
applied and the period of 12 months provided in Section 135 cannot be extended.
5.2.7 Priority date not allowed after withdrawal of basic application for an application
made under section 135: - An application no, 986/Cal/79 was filed on 21.09.1979 as
conventional application based on U.K. application no. 37624/1979. However, the
basic U.K. application was withdrawn before filing of the Indian application. The
applicant argued that the priority of the withdrawn application should be allowed on
the basis of said U.K. application as the same has the filing date and number and was
mentioned in the statement of undertaking. The Controller of Patents however held
that existence of application in the convention country at least on the date of filing the
application in India is sine-quo-non for the claim of priority. Since the application in
109
the convention country has been withdrawn prior to the date of filing of application
India the requirement of under section 135 have not been met and in fact in the eye of
law there was no application in the convention country in consequence of withdrawal.
Therefore, the priority date on the basis of withdrawn application could not be
allowed.
Rule 15:
Drawings.
(1) Drawings, when furnished under section 10 by the
applicants otherwise than on requisition made by the Controller,
shall accompany the specifications to which they relate.
(2) No drawings or sketch, which would require a special illustration of the
specification, shall appear in the specification itself.
(3) At least one copy of the drawing shall be prepared neatly and clearly on

1. Ordinary Application
110
2. Convention Application
3. PCT International Application
4. PCT National phase Application
5. Application for Patent of Addition
6. Divisional Application
An application for patent made in the Patent office without claiming any priority
of application made in a convention country or without any reference to any other
application under process in the office is called an ordinary application. Such an
application can be filed by an inventor himself (as an applicant ) or by a person to
whom the invention is assigned by the inventor (an assignee is the applicant),
without claiming any priority of application made in a convention country or
without referring to any other application being processed in the Patent Office.
The applicant can be either of Indian or foreign origin.
When two or more applications for patents constituting one invention have been
made in one or more convention countries, one application may be made within
twelve months from the date on which the earlier or earliest of those applications
was made. Multiple fees has to be remitted for claiming multiple priorities
(S.137), so that other applications filed earlier in the convention countries, will be
deemed to have been published in India. An applicant of convention application
shall furnish when required by the Controller, the copies of specification or
documents (priority documents) certified by the official chief of the patent office
of the convention country.
PCT is an International filing system for patents in which the applicant gets an
international filing date in all the designated countries, conferring the late entry (up
to 31 months) to the national offices without affecting the priority date. This is a
simple and economical procedure for the applicants seeking protection for their
inventions in many countries. Indian Patent office is a Receiving office for
International Applications by nationals or residents of India. ((see Rules 17-23 in
Chapter V))
111
An international application shall be filed with the appropriate office under Rule(4)
in triplicate either in English or in Hindi language
When an applicant feels that he has come across an invention which is a slight
modification of the invention for which he has already applied for / has patent the
applicant can go for patent of addition since the invention does not involve a
substantial inventive step. It is also possible to convert an independent patent to a
patent of addition at a later date if the subject matter was an improvement in or
modification to a main invention for which he holds a patent. There is no need to
pay separate renewal fee for the patent of addition during the term of the main
patent. A Patent of Addition expires along with the main patent unless it is made
independent according to the provisions in Section 54
However a Patent of Addition will not be granted unless the date filing of
Application was the same or later than the date of filing of the complete
specification in respect of the main invention
It should be noted that a patent of addition will not be granted before granting of the
patent for the main invention. (see Chapter IX also)
112
The prime requirement of the patent law is to protect the invention disclosed in the
specification. The specification is a techno-legal document containing scientific
information constituting patent rights. The specification, thus, forms a crucial part
of the patent documents. It is mandatory on the part of the inventor to disclose
clearly and completely various features constituting the invention. Under the
patent law, the disclosure is in the form of provisional and complete specification
as the case may be. Various features of these specifications are discussed in this
section .
When the applicant finds that his invention has reached a presentable form but
not the final shape, he may prepare a disclosure of the invention in the form of a
written description and submit it to patent office as a Provisional Specification
which describes the invention.
113
of Provisional Specification to claim legal right, but, to obtain priority
of invention.
(b) The description should start from the second page starting with
the field of invention and containing the background of the invention,
object of the invention, statement of the principle underlying the
invention and general statement of the actual invention. It is advisable
to include in the Provisional Specification as much information as the
applicant has at the time of filing, but in any case the description should
be adequate to identify the invention from the prior art.
114
The Complete specification is a techno-legal document which fully and
particularly describes the invention and discloses the best method of performing it.
i) The Complete Specification must be framed with utmost good faith and
must not contain any false representation or description of the invention or
any material part of it, which would otherwise mislead the public. The
Complete Specification must not be framed in ambiguous languages but must
be as clear and concise as the nature of the subject would admit.
iii) If the Complete Specification describes anything, which is not new, it must
be clearly distinguished from the novel features of the invention
v) If the inventor does not disclose all the relevant information or mislead the
public or gives a false description of the invention, the patent would be
liable to be revoked.
vii) It is not enough if a mere list of the various parts that make up the
apparatus or device is given. The mode of construction of the apparatus
and the function of its different parts should be described.
115
iii) The description should start from the second page of Form 2 followed by
statement of claims for which protection is sought and end with the date and
signature of the Applicant or his authorized agent.
c) Priority Document should be submitted within three months from the date
when required by the Controller (S.138(1)). If the document is not in
English, then a translated copy should be furnished (S.138(2)).
f) Proof of Right (if the application is made by the assignee (S.7 (2) & R
10) (Proof right to apply can be produced either in the body of the
application (Declaration by the Inventor(s) /Applicant(s) in the
convention country in Form 1) or by way of separate assignment deed.
If the application is made by the legal representative ‘death certificate
or probate or certificate of inheritance’ of the deceased should be filed
as proof of right. Proof of right shall be submitted within six months
from the date of application.
116

e) Such period of delay condoned by the Controller shall not exceed the
period between the date on which the party was supposed to have received the
document or communication by ordinary course of mail or electronic
transmission and the actual date of receipt of the same.
Claims are considered to be the most important part of the patent document. In a
complete specification the description is followed by the Statement of Claims.
Since the claims constitute the legal part for claiming the protection of the
patent rights, it is imperative that the claims should be drafted carefully to cover
all the aspects of the protection being sought. while observing the following
points:
(a) Each claim should be in a single sentence and should be clearly and
worded
(b) Claim(s) should be succinct and should not involve unnecessary
repetition
o(c) A claim (s) should not be verbose.
o(d) A claim is the statement of technical facts expressed in legal terms
defining the scope of the invention sought to be protected.
124
o(f) Claims define the boundaries of legal protection sought by the
patentee and form a protective fence around the invention which is
defined by the words and phrases in the claims.
o(g) The object of claims is to define clearly the scope of the invention
with conciseness, precision and accuracy the monopoly claimed, so
that others may know the exact boundaries of the area of protection in
which they should not trespass.
o(h) Their primary object of claims is to limit and not to extend the
monopoly unduly and, simultaneously, also let others know when they
are infringing on the rights of the patentee.
o(i) Each claim is evaluated on its own merit and, therefore, if one of the
claims is objected, it does not mean that the rest of the claims are
invalid. It is therefore important to make claims on all of the invention
to ensure that the applicant gets the widest possible protection.
o(a) As the value of a patent depends largely upon the scope of the claims, special
care is necessary to ensure that the claims are drafted to include neither more
not less than what the applicant desires to protect by his patent.
o(b) Claims must not be too extensive so as to embrace more than what the
applicant has in fact invented. A claim, which is too wide, encroaches upon the
subject matter, which may be in public domain or belong to others.
o(c) However a claim must not be too narrow also because such a claim would not
be sufficiently effective in preventing infringement of the patent. An infringer
would go scot-free, if the claim were too narrow and , hence, the full benefit of
invention may not accrue to the inventor.
o(d) Having many claims, where each one has a different scope, allows the
applicant to have legal title to several aspects of the invention. In a good
drafting, it begins with broad claims and develops towards claims that are
narrower in scope. In general, a narrow claim specifies more details than a
broader claim.
o(e) Passages which confuse the scope of the invention or claims that are
unspecific (e.g. those claiming “Any novel matter...” ) should not be filed
o(f) A claim shall be for the protection of either a product or process or apparatus
or all of them, as the case may be, and shall be in one sentence according to
the standard practice .
125
oa. The description of invention in the complete specification is to be
followed by a “statement of claims” preceded by the prescribed
preamble, “I or we claim” as the case may be.
ob. Claims should start from the fresh page after full description of the
invention with the claims serially numbered.
o(e) In addition, any term, which is used in the claims, must be either found in the
description or clearly inferred from the description.
o(f) Trade marks are an indication of the origin rather than the composition or
content of goods, and should not be used in patent applications where a
generic term can be used instead. Trade marks are only permitted in claims
where it can be shown that their use is unavoidable and does not introduce
ambiguity . Where marks that are registered are mentioned, they should be
acknowledged as such. If a trade mark is not registered, its owner should be
indicated
- Introductory phrase,
- Body of the claim, and
- Link that joins the two segments.
126
o The introductory phrase identifies the category of the invention and
sometimes the purpose (For example, a machine for waxing paper, a
composition for fertilizing soil).
o The body of the claim is the specific legal description of the exact invention,
which is sought to be protected.
For Example:
a) Independent Claim :
This is the first claim which is also called the ‘Principal Claim’ should
clearly define the essential novel features of the most preferred embodiment
of the process, apparatus, device or the product that constitutes the invention
and should be properly characterized with respect to the ‘prior art’, defining
all the technical features essential to the invention or inventive concept.
This should include the core integers as well as sufficient details of
interrelationship, operation or utility to establish that the invention
achieves the intended objectives and
b) Dependent Claim(s)
Dependent claims should be clubbed with the independent claims (or within
themselves) to include all the features of the independent claim and
characterized by additional non-essential features and even the minute aspects
and optional features.
127
c) Further independent claims are only justified where the inventive concept
covers more than one category, e.g. apparatus, process, product,
complementary versions within one category constituting unity of invention,
e.g. plug and socket, transmitter and receiver, which work only together.
d) Omnibus Claim :
5.3.5 In Ram Narain Kher vs. M/s. Ambassador Industries New Delhi and another
[AIR 1976 Delhi 87], it was observed:- When an invention is not itself
new, the particular use of it for the purpose described in combination with
the other elements of the system producing the advantageous results would
be a sufficient element of novelty to support the Patent and in a claim for
Patent pertaining to air cooler the claimant must specify what particular
features of his device distinguish it from those which had gone before and
show the nature of the improvement which is said to constitute the
invention and the claim that there would be 25 per cent additional
advantage of added cooled air by fixing the fan at the top of the cooler than
in the customary way hitherto known in the front of the cooler must be
succinctly stated in the claim before the Patent authority and must not
be left to an inference raised on a general review of the specification.
Example of Claims :
o(a) “An apparatus for catching mice comprising, a base member for placement
on a flat surface, a spring member…”
128
o(b) “A chemical composition for cleaning windows which comprises 10-15%

The following examples, as sample claims, which have been granted by the Patent
Office, are given for the purpose of providing help to the applicant in drawing up the
Claims. They must, however, be regarded as samples of varying quality, selected
more or less at random and no guarantee is given that they would be effective in a
court of law.
i) Indian Specification No. 39285.
130
“We claim :-
1. A wrapper for a package, having a tear-tape united to its outer surface, the
area of the wrapper to which the tear-type is united encircling the package
and being bounded along at least one edge by perforations.
2. A wrapper as claimed in Claim I in which a narrow area of the tear tape,
spaced from each edge of the tear-tape, is united to a narrow area of the
wrapper defined on each side by a line of perforations which are covered by
the outer portions of the tear-tape, the perforations facilitating tearing of the
wrapper to remove the portion bounded to the tear-tape.”
“We claim :-
1. A gramophone record in which the surface of the record containing the record
grooves comprises 12 to 15 per cent of amorphous carbon, thermoplastic

131
5.3.7 How to Assess Clarity of Claims ?
i) Example: 1
ii) Example:2
The syntax of the claim is open to different interpretation: Either the engine block
as well as the cylinder head are made of the alloy, or only the cylinder head is
made of the alloy.
iii) Example:3
The camera is defined in terms of the object to be achieved (operation at very low
temperatures) rather than in terms of the technical features (e.g. selected
semiconductor materials, thermal insulation, etc.) that achieve the desired object.
The claim attempts to define the subject matter in terms of the result to be
achieved. In this instance, however such formulation is not allowable because it
appears possible to define the subject-matter in more concrete terms, i.e. in terms
of how the effect is to be achieved.
iv) Example:4
In case of Anup Engineering Ltd.v Bharat Heavy Electricals Ltd. (1985 PTC 71).
In the instant case, in regard to the ground of 'unfair description' the opponents
have stated that important data like the dimension of the bellows produced and
hydraulic pressure within the hydraulic forming machine have not been disclosed
in the specification. Having regard to the fact that the invention claimed in
statement of claims relates not to bellows but to apparatus for manufacturing
bellows, these materials are not essential features of the invention. In regard to
other defects like omission of reference numerals in the drawings accompanying
complete specification and support of some claimed feature in the description;
these defects are not of such nature as to make the alleged invention not clear or
render the statement of claims ambiguous. These defects could have been
corrected by effecting minor amendments in the description. The complete
132
specification does not sufficiently and clearly describe the invention. The
opponents, accordingly, have established this ground.
Example:
“The process for the manufacture of dyes which comprise coupling with a halogen
substituted pyrazolone, a di-azotized unsulphonated material selected from the
group consisting of aniline, homologues of aniline and halogen substitution
products of aniline.”
ii) Also, the claims should not be made, as in the examples given below, for
illustrating the efficiency or advantages of the invention:-
a) I claim that this device is better and cheaper and more effectual
than anything known.
b) I claim that my process or machine will do such and such things
133
c) I claim the following advantages.
d) I claim an improved sewing machine
e) I claim a mechanism for converting heat into electrical energy
without any loss of efficiency.
f) I claim a new method of making silk waterproof.
iii) Where products are claimed, the invention will not be properly defined if
merely the properties of the products are referred to, as in the following
example:-
o(a) a claim for a product and claim for a process specially adapted for
manufacture of the product;
o(b) a claim for a process and claim for an apparatus or means specifically
designed for carrying out the process;
o(c) a claim for a product, claim for a process specially adapted for
manufacture of the product and claim for an apparatus or means specifically
designed for carrying out the process.
However , the above criteria can not be generalized and there may be occasions
where all such claims may not be allowed in a single application based on the
circumstances of the case.
Example:1
o(a) Unity between product and process claims requires that the process
inherently results in the product when the novel product is obtained by
the claimed process.
134
o(b) Unity between process and apparatus or means requires that the
apparatus or means have been specifically designed for carrying the
process, or at least a step of the process, but without excluding any
other possible use.
Example:2
Example:3
If one has invented a new kind of spray bottle, the invention can be claimed in
the same application for :
·(a) The spray bottle itself (a product)
·(b) Method of making the spray bottle (a process)
·(c) Apparatus used for making the said spray bottle
Example:4
When a genetically modified Gene Sequence/ Amino Acid Sequence is novel,
involves an inventive step and has industrial application, the following can be
claimed.
·(a) Gene sequence / Amino Acid sequence
·(b) A method of expressing above sequence
·(c) An antibody against that protein / sequence
·(d) A kit made from the antibody / sequence
All of these claims are linked by the inventive concept if the genetically modified
sequence is new, inventive and has industrial application
Example:5
A drug or pharmaceutical product, if it is novel, inventive and has industrial
application, can be claimed for the following:
(a) a drug or pharmaceutical product,
(b) modified drug or pharmaceutical of a known compound, if proved to be more
efficacious than the known compound
(c) a process of making the product as defined in (a) or (b).
(d) formulation containing the drug (a) or (b)
135
Example:6
In case of a herbal, chemical or pharmaceutical or a medicinal composition the
following can be claimed:
(a) a product by itself, if it is novel
(b) a process of extraction and/or process of mixing the ingredients either pre-
prepared or extracted.
(c) Apparatus, if novel, either for the process of extraction and/or for the process
of preparation.
Example:7
In case of non-drug or non-pharmaceutical chemical, the following can be claimed:
(a) product, if it is novel
(b) process of making the chemical
(c) apparatus for the preparation of a chemical, if it is novel
Example:8
A Biopolymer produced from a genetically modified bacterium can be claimed for
the following (Accession Number of the bacterium & Name of the International
Depository Authority should be mentioned in the complete specification) :
·(a) Biopolymer, if it is novel
·(b) Genetically modified bacteria for producing the above said Biopolymer, if it is
novel
·(c) Process of manufacturing genetically modified bacteria
·(d) Process for manufacturing the said biopolymer

5.4.1 SUFFICIENCY OF DISCLOSURE
i) The Complete Specification describing the invention is a techno-legal document. It
should disclose the invention completely to meet the requirement of the Patents
Act and should also enable a person possessing average skill in the art to work
the invention without assistance of the patentee . This is possible when the
complete specification describes the invention fully and particularly and
136
describes its operation and/or method by which it is to be performed. It is also
essential that the best method for performing the invention, which is known to
the applicant is disclosed in the Complete Specification . [S. (10)(4)].
ii) If the applicant mentions biological material in the invention and it is not possible
to describe the same in the complete specification, requirement of sufficiency of
disclosure can be completed by depositing such material in an International
Depository Authority under the Budapest Treaty. The same shall be deposited
not later than the date of filing, however, the reference number to the deposit
shall be made in the specification within 3 months from the date of filing the
application. The complete specification shall contain the details of such
deposition and the source and geographical origin of the biological material.
iii) It is thus clear that the complete specification, , should disclose the invention
completely so that a person skilled in the art can perform the invention.
The technical advance, synergistic effect and efficacy of the claimed invention
must be substantiated properly in the body of specification as well as by way of
suitable examples.
Example:1
Example:2
The ordinary skilled person must be able to perform the invention which satisfies
the requirement of disclosure. The test for enablement of a prior disclosure for
the purpose of anticipation is the same as the test of enablement of the patent
itself for the purpose of sufficiency [ held in SmithKline Beecham Plc’s
(Paratoxetine Methanesulfonate) Patent [2006] RPC 10 ].
There may however be differences in the application of this test to the facts;
for example, because in the case of sufficiency the skilled person is attempting
to perform a claimed invention and has that goal in mind, whereas in the
case of prior art the subject-matter may have disclosed the invention but not
identified it as such and it is to be judged from the point of view of the person
skilled in the art .
137
“It is the duty of a patentee to state clearly and distinctly the nature and limits
of what he claims. If the language used by the patentee is obscure and
ambiguous, no patent can be granted, and it is immaterial whether the
obscurity in the language is due to design or carelessness or want of skill. It
is undoubtedly true that the language used in describing an invention would
depend upon the class of person versed in the art and who intend to act upon
the specifications. In the present case, the invention is described in an
obscure and ambiguous language, and on this ground, the patent is liable to
be refused”
ii) Since disclosure of the invention is the consideration in return for which
the applicant is granted a monopoly the highest degree of good faith is called
for, and the disclosure should be clear, precise, honest and open. A
designedly ambiguous description or one that is wanting in distinctness,
either by negligence or unskillfulness , will invalidate a patent (British Ore
Concentration Syndicate Ltd v Minerals Separation Ltd, 27 RPC 47;
Cincinnati Grinders (Inc) v BSA Tools Ltd 48 RPC 33).
v) The description should not contain passages which confuse the scope of
the invention. Therefore, phrases such as “ the invention should be taken to
include any modifications, whether novel or not...” are unacceptable.
138
iv) Terms already having an established meaning should not be used
differently, if this is likely to cause confusion. But in some
circumstances it may be appropriate for a term to be borrowed from an
analogous art.
ii) The disclosure must be sufficient to enable whole width of the claimed
invention to be performed. It was held that the disclosure of a single
embodiment will not always satisfy the requirement regardless of the
width of the claim [Biogen Inc v Medeva plc [1997] RPC 1].
iii) It was held in Kirin-Amgen Inc v Hoechst Marion Roussel [2005] RPC
9 that whether the specification is sufficient or not was highly sensitive
to the nature of the invention. To determine this question, the first step
was to identify the invention and decide what it claimed to enable the
skilled man to do. It was then possible to ask whether the specification
enabled him to do it.
139
also insufficient if it provides no teaching relating to the criteria according
to which the skilled man is taken to be using the invention.
v)
What will suffice to satisfy the criterion that the disclosure must be
sufficient across the whole width of the claimed invention will vary
depending upon the nature of the claim. Thus, for example, when there
is more than one product which is claimed, the question has to be asked
whether the invention of one product is the invention of the other, unless
they are different inventions and each must be sufficiently described. A
similar conclusion had been reached by the Court of Appeal in the case
and Chiron Corp. and ors v Murex Diagnostics Ltd and ors [1996]
RPC 535 (pages 612 and 613).
5.4.5 General Guidelines For Applicant for Filing
140
as the inventor’s idea of the nature of the invention has taken a definite
shape. In this connection inventors should note that it is permissible to file an
application for a patent accompanied by a “Provisional Specification”.
The inventors should not neglect to get clarification of their rights with
reference to those of their employers, co-workers, contractors and assistants,
if any, with whom they are brought into contact in the course of the
development of their inventions. Negligence on this account may lead to loss
of right and costly litigation.
Section 10(4)A:
In case of an international application designating India, the title,
description, drawings, abstract and claims filed with the application
shall be taken as the complete specification for the purposes of this Act.

(1) The provisions of this Chapter shall be supplemental to the PCT and the
regulation and the administrative instructions made there under.
143
(2) In case of a conflict between any provisions of the rules contained in this
Chapter and provisions of the Treaty and the regulations and the

and the regulations and administrative instructions made there under
shall apply in relation to international applications.
On 7th September 1998, India deposited its instrument of accession to the PCT
and on 7th December 1998 thus became a member of the PCT, as the 98th
Contracting State of PCT. The Patent Offices at Kolkata , Mumbai, Chennai and
New Delhi are receiving the PCT applications.
The principal objective of the PCT is to simplify the patent system over the
previously established means of applying for patent protection in several
countries for inventions and to render it more effective and more economical in
the interest of the users and the national patent offices, that have responsibility
for administering PCT. Before introduction of the PCT system, virtually the only
means by which protection of an invention could be obtained in several countries
was to file a separate application in each country. Each of the application is dealt
with in isolation, and thus, involves repetition of the work of the filing and
examination in each country.
144
made available first to the applicant and is later published; An exhaustive written
opinion on patentability is also provided by ISA.
The procedure described under PCT involves two steps of processing the
international application. The “International Phase” deals with conducting the
search and allowing the applicant to amend the claims, if required. It also
optionally deals with the international preliminary examination. Thereafter, the
applicant has to enter the national phase (within the prescribed time limits). The
grant of patent is the task of the designated / elected offices, that is, the national
offices or regional offices.
Under the PCT system, by the time the International Application reaches the
national / designated Office, it has already been searched by the International
Searching Authority and possibly examined by an International Preliminary
Examining Authority, thus providing the national Patent Offices with the
important benefit of reducing their work loads since they have the benefit of
these international phase centralized procedures and, thus, need not duplicate
those efforts. Further, objectives of the PCT are to facilitate and accelerate
access by industries and other interested sectors to technical information related
to inventions and to assist developing countries on gaining access to technology.
145
b) The receiving office shall accord as the international filing date; the date of
receipt of the international application, provided the application is in order in
accordance with Article 11 of PCT, at the time of receipt.
c) If the receiving office finds that the international application did not, at the time
of receipt, fulfill the requirements listed in paragraph (a), it shall, as provided
in the Regulations, invite the applicant to file the required correction(s).
4. Receiving Office checks certain formal and physical requirements (Article 14)
as to form and content and whether the fees are not, or not fully, paid. In that
case, the Receiving Office communicates with the applicant in order to give him
an opportunity to correct any defect.
In cases, where the applicant fails to furnish, within the applicable time limit, a
translation for the purpose of international search, the Receiving Office invites the
applicant to furnish the missing translation, in certain cases subject to the payment
of a late furnishing fee. A separate invitation procedure is provided for the case
where the request does not comply with language requirements. Where the
applicant does not furnish the missing translation within the time limit fixed in the
invitation, the International application will, subject to certain safeguards for the
applicant, be considered withdrawn and the Receiving Office will so declare.
146
8. Typical examples of defects, which may be corrected without affecting the
international filing date, are:
9. In all such cases, lack of correction leads to the application being considered
withdrawn, except where a physical defect would not prevent reasonably uniform
international publication and except for the payment of fees. With regard to the
later, PCT rule 16 bis provides that the Receiving Office must invite the applicant
to pay the missing fees together with a late payment fee. If the applicant still does
not pay the fees within the time limit fixed in the invitation, the Receiving Office
will declare that the International Application is being considered withdrawn. This
solution protects the applicant against any loss of his application due to an
erroneously delay or incomplete payment of fees.
10. The next step in the procedure before the Receiving Office is that it must
transmit the “record copy” of the international Application to the International
Bureau and the “search copy” to the International Searching Authority. The
Receiving Office keeps a third copy, the “home copy”. The transmittals do not
take place if, and as long as, national prescriptions concerning national security
apply. The Receiving Office will then declare that national security provisions
prevent the International Application from being treated as such.
11. The Receiving Office must mail the record copy promptly to the International
Bureau and in any case not later than five days prior to the expiration of the 13th
month from the priority date. In many cases, the International Application claims
the priority of an earlier national application and is filed at the end of the 12-month
priority period; the Receiving Office has only a few weeks for its processing tasks.
12. The search copy must be transmitted by the Receiving Office to the International
Searching Authority at the time of the transmittal of the record copy of the
International Bureau except, where the search fees has not been paid on time, in
which case, the transmittal of search copy takes place after that fee has been paid.
147
payment of a fee equal to the transmittal fee. All other fees, already paid to that
Office, will be refunded by that Office to the applicant and the applicable fees will
have to be paid to the International Bureau as Receiving Office.
( ii) The applicant should be resident or national of the Contracting State for which
the Receiving Office acts, and has consequently the right to file with that
Receiving Office (note, however, that the International Application is to be
transmitted to the International Bureau as Receiving Office under Rule
19.4(a)(i), if that condition is not fulfilled);
iii) The International Application should be in English or Hindi (note, however, that
the International Application is to be transmitted to the International Bureau as
Receiving Office under Rule 19.4(a)(ii), if that condition is not fulfilled
(v) If one of these requirements is only complied with after correction, the
international filing date will be the date on which the correction was received.
In other words, in these cases a defect, which is corrected later, affects the
international filing date. If all such defects are not properly corrected, the
application will not be treated as an International Application.
(vi) For all the other cases, non-compliance with the formal requirements does not
affect the international filing date. In other words, if the applicant corrects a
defect in such cases, the international filing date remains unchanged. If the
applicant does not correct, the defect properly, the International Application
will, however, be considered withdrawn by the Receiving Office. Extension of
the time limit fixed by the Receiving Office for the correction of defects under
Article 14 may be requested.
148
5.4.13 Monitoring of time limits
Easy supervision and monitoring of only a few time limits and events is
required by applicants, namely:
(iii) Deciding, after the receipt of the international search report, whether or
not to file amended claims under Article 19, within the applicable time limit.
(iv) Monitoring the receipt, during the 19th month from the priority date, of
the notice from the International Bureau (Form PCT /IB / 308) that the
publication of the International Application has been effected.
(v) Deciding, after receipt of the international search report, whether or not
to file a demand for international preliminary examination (which must be
filed prior to the expiration of 22 months from the priority date.)
(vi)Entering the national phase before the expiration of 20/21 or 30/31 months
from the priority date or international filing date, whichever is earlier, by
paying the national fees and furnishing (if required) a translation of the
International Application with duly verified for its correctness and
completeness.
1. International Application must be filed with any of the receiving offices i.e
Patent office, Kolkata (RO/IN), New Delhi Mumbai, and Chennai or
International Bureau (RO/IB) of WIPO. The request form and the documents
attached therewith should be in triplicate. An application for the same
invention has to be filed in India not less than six weeks before filing the
International application or necessary permission under section 39 should be
taken before filing the international application. The request for permission
(U/S 39) for making patent application outside India including PCT
international application should be made in form 25 with the prescribed fee as
given in First Schedule (sub rule 1 of rule 71) and the Controller shall dispose
the said request ordinarily within a period of 21 days from the date of filing of
such request (sub rule 2 of rule 71).
149
3. The Request may be made on Form PCT / RO / 101, copies of which can
be obtained free of charge from the Receiving Office or from the International
Bureau of WIPO or can be downloaded from WIPO website. The request
may also be presented as a computer printout as prescribed by Section 102(h)
of the PCT Administrative Instructions or, alternatively, as a computer
printout prepared using the PCT-EASY software, in which case it must be
accompanied by a computer diskette containing a copy of the data as
contained in the request in electronic form and copy of the abstract
4. The request must, first of all, contain a petition, that is, a request that the
International Application be processed according to the PCT. It must further
contain the title of the invention with necessary data concerning the applicant,
the inventor and the agent representing the applicant. It must be signed by the
applicant or his agent. Declaration of inventorship should be signed by the
inventor(s) / the applicants in convention country as applicable and not by the
agent. Where there are two or more applicants, each applicant must sign at his
choice either the request or, if the request is signed by an agent, a separate
power of attorney. The request should also contain details of priority (where
applicable) and an indication of competent International Searching Authority.
b) Priority
1. A certified copy is required for each priority of the application and the
same is to be furnished within 16 months from the priority date; The copies
for the designated offices are prepared by the International Bureau at no
additional cost to the applicant –.
2. A request for transmittal of a copy of the priority document filed with the
Receiving Office ,by the Receiving Office to the International Bureau, can be
made in the Request Form and the applicable fee for a priority document paid
to the Receiving Office.
c) Description
150
carrying out the invention and any other mode he wants to include. Finally, it
indicates the way in which the invention is capable of exploitation in industry.
d) Sequence Listing:-
e) Claims:
1. The claims must define the subject matter of the invention for which
protection is sought. They must be clear and concise and fully supported by
the description.
f) Drawings:
The drawings are only required where they are necessary for the
understanding of the invention. This will be the case for example for an
engineering type of invention. It will not be the case when an invention
cannot be drawn, as is the case for a chemical product. Here again, the
requirements are similar to those of most Patent Offices.
g) Abstract:
151
understanding of the technical problem, the gist of the solution of that problem
through the invention, and the principal use of the invention.
h) Language of filing
Neither the Treaty nor the Regulations enumerate the languages in which
International Applications may be filed. Whether a given language can be
used depends on the readiness of the Receiving Office to accept International
Applications in that language. Each Receiving Office must, however, accept
at least one language for the filing of International Applications, which is both
a language accepted by at least one international Searching Authority,
competent for the international searching of International Applications filed
with that Receiving Office and one of the language of publication (that is,
Chinese, English, French, German, Japanese, Spanish, Russian or Arabic). In
other words, either the International Application in its original language or the
translation will be sufficient for the processing by the Receiving Office, for
international search and for international publication.
152
international search report is normally available in time before publication of
the International Application. This allows time for the applicant to withdraw
the application before publication, if desired.
Receiving Office (RO/IN) is The Patent Office, Kolkata, New Delhi Mumbai
and Chennai
All PCT fees are subject to change periodically. For latest fees, please refer
the latest PCT newsletter at URL www.wipo.int.
Failure to pay fees or underpayment of fees can be corrected under PCT rule
16 bis. An invitation to pay missing fees will be issued by the Receiving
Office. Payment can be made within a month from International filing date or
later with a late payment fee.
The Transmittal Fee is for the benefit of the Receiving Office. It is intended
to compensate that office for the work, which is required to be performed in
connection with the International Application. The amount is fixed by the
Receiving Office. It is to be paid within one month from the date of receipt of
the International Application.
The international filing fee is for the benefit of the International Bureau. It is
intended to cover the cost of the work; the International Bureau must perform
under the PCT. The amounts are fixed in the Schedule of Fees, which forms
part of the regulations. The international filing fee is to be paid within one
month from the date of receipt of the International Application.
The Search Fee is for the benefit of the International Searching Authority. It
is intended to compensate that Authority for the work it must perform in
connection with the establishment of the international search report. It is also
to be paid within one month from the date of receipt of the International
Application. The amount is fixed by the International Searching Authority.
153
An International Application can be withdrawn before technical preparations
for international publication have been completed (that is, not later than 15
days before the date of publication , which is 18 months from the priority
date)
5.4.18 Amendments:
The claims can be corrected for conformity with the results of the
international search report by amending them once (under Article 19) with
effect in all designated States. Such amendments save costs for preparation of
different sets of amendments and for local agents filing such amendments
before designated Offices, and guarantee better provisional protection and
patents in designated countries. Individual amendments before each
Designated Office are also permitted in the national phase (under Article 28 or
41) and all parts of the application can be amended under Article 34(2))
during the international preliminary examination procedure under Chapter II.
iv) allows, with effect for all elected Offices, the amending of all parts of
International Application (description, claims and drawings) during
international preliminary examination;
vi) If the report is negative and it is decided to abandon the application, the
applicant has saved all the expenses otherwise incurred before the elected
Offices for the payment of national fees, the preparation of translations and
the appointment of local agents. However the opinions from ISA & IPEA are
non-binding opinions for the member countries
2. The following are Competent International Preliminary Examining
Authorities (IPEAs) for the purpose of Indian Applicant:]
154
• Swedish Patent Office (SE)
The fees to be paid by the applicant when he opts for Preliminary examination
to be carried out by IPEA is given in the PCT Newsletter which is available on
the WIPO website, www.wipo.int
1. The national phase follows the international phase. In the national phase
before processing and examination in the designated or elected Offices, the
applicant must perform certain acts thereby effecting “entry into the national
phase”. If the applicant does not enter the national phase, namely, if he does
not perform these acts within the prescribed time limit, the International
Application loses its effect in the designated or elected States concerned with
the same consequences as the withdrawal of any national application in that
State (Article 24).
2. For entry into the national phase before a designated office, it is necessary
that the national fee is paid to it and, where the International Application has
not been filed or published in the official language, or one of the official
languages of that Office, a duly verified translation into an official language
be filed. The time limit for entry into the national phase is 31 months in India.
3. The national fees to be paid are usually same as the fees required for the
filing of a national or conventional application.
(i) The same application documents can be used for filing national
application;
(ii) No adaptation of the original application is then required in as
much as the PCT format is valid for all designated offices (including the EPO,
the Japanese Patent Office and the United States Patent and Trademark
Office).
(i) Under the basic requirements to start the national phase in India, the
applicant is required to file the national phase application within 31 months
from the priority date or International application date, whichever earlier.
(ii) Application may be made in Form 1.
(iii) National fee in INR is to be paid as given in the First Schedule along
with the application.
(iv) In case of more than one priority, multiple fees for every multiple
priority is to be paid as per the First Schedule
155
(v) Where the international application has not been filed or published in
one of the official languages (Hindi or English), a translation of the
application, description, claims (if amended, both as originally filed and
amended together with any statement under PCT Article 19 and Article
39(1)), drawings, if any, and abstract should be submitted along with the
application.
a) Name, nationality and address of the inventor if they have not been
furnished in the “Request” part of the international application,

under sub-section (2) of section 5 before the 1st day of January, 2005 shall
accrue from the date of grant of the patent:
Provided also that after a patent is granted in respect of applications made
under sub-section (2) of section 5, the patent-holder shall only be entitled to
157
receive reasonable royalty from such enterprises which have made significant
investment and were producing and marketing the concerned product prior
to the 1st day of January, 2005 and which continue to manufacture the
product covered by the patent on the date of grant of the patent and no
infringement proceedings shall be instituted against such enterprises.
Section 143:
Restrictions upon publication of specification;
Subject to the provisions of Chapter VII, an application for a patent, and any
specification filed in pursuance thereof, shall not, except with the consent of the
applicant, be published by the Controller before the expiration of the period
prescribed under sub-section (1) of section 11A or before the same is open to
public inspection in pursuance of sub-section (3) of section 11A or section 43.
Rule 11:
Order of recording applications.
The applications filed in a year shall constitute a series identified by the year
of such filing. In case of an application filed corresponding to an international
application in which India is designated, such application shall constitute a
series distinct from the rest of the applications identified by the year of filing of
corresponding applications in India
Rule 24:
Publication of application
The period for which an application for patent shall not ordinarily be open to
public under sub-section (1) of section 11A shall be eighteen months from the
date of filing of application or the date of priority of the application, whichever
is earlier.
Provided that the period within which the Controller shall publish the
application in the Journal shall ordinarily be one month from the date of expiry
of said period, or one month from the date of request for publication under rule
24A.

Rule 27:
Inspection and supply of published documents;
After the date of publication of the application under section 11A, the
application together with the complete specification and provisional
specification, if any, the drawing, if any, and the abstract filed in respect of the
application may be inspected al the appropriate office by making a written
request to the Controller on payment of the fee in that behalf and copies thereof
may be obtained on payment of fees specified in the First Schedule.
Patent office accords an application number and filing date to the application
immediately after filing by the applicant, such that the applications filed in a year
constitute the series identified by the year of such filing. PCT National Phase
applications constitute a different series (Rule 11).
All the applications will be screened and have International Patent Classification to
categorize the invention to the respective field of technology. Simultaneously, the
applications are screened to find whether the invention is relevant for defence and
atomic energy purpose so that the necessary procedure can be initiated.
A) No application for patent shall ordinarily be open to public before the publication
by Patent office under section 11A. At the end of 18 months period, the application
will be published in the official journal except in the cases where,
iii) It has been withdrawn three months prior to the publication period i.e. before
the end of 15th month from the date of filing or priority, whichever is earlier
[S.11(A)].
In case a secrecy direction has been given, the application will be published after
expiry of the 18-month period or when the secrecy direction is lifted off, whichever
is later (S. 11A(4)).
159

invention disclosed in the provisional or complete specification already filed in
respect of the first mentioned application.
(2) The further application under sub-section (1) shall be accompanied by a complete
specification, but such complete specification shall not include any matter not in
substance disclosed in the complete specification filed in pursuance of the first
mentioned application.
(3) The Controller may require such amendment of the complete specification
filed in pursuance of either the original or the further application as may be
necessary to ensure that neither of the said complete specifications includes a
claim for any matter claimed in the other.
Explanation.—For the purposes of this Act, the further application and the complete
specification accompanying it shall be deemed to have been filed on the date on which
the first mentioned application had been filed, and the further application shall be
proceeded with as a substantive application and be examined when the request for
examination is filed within the prescribed period.
Section 17:
Power of Controller to make orders respecting dating of application;
(1) Subject to the provisions of section 9, at any time after the filing of an
application and before the grant of the patent under this Act, the Controller
may, at the request of the applicant made in the prescribed manner, direct that
the application shall be post-dated to such date as may be specified in the
request, and proceed with the application accordingly:
166
Provided that no application shall be post-dated under this sub-section to a
date later than six months from the date on which it was actually made or
would, but for the provisions of this sub-section, be deemed to have been
made.
i) The application will be taken up for examination only on request made by the
applicant or by any other interested person in Form -18. Such a request is
required to be made within 48 months from the date of priority or from the

application starts only after expiry of 31 month -period from its priority date
(Rule 20(2) and 20(4)). However an express request can be filed for early
processing or examination, any time earlier than the prescribed time of 31
months, in Form 18 along with the prescribed fee as given in First Schedule,
whereupon these applications may be taken up for examination before the said
period
iv) All the applications will be screened to categorize the invention to the
respective field of technology and to find whether the invention is relevant for
defence purposes etc. so that the necessary procedures can be initiated in
respect of those applications.
v) In respect of applications filed u/s 5(2), filed before the 1st day of January
2005, the request should be made within a period of 48 months from the date
of priority (if applicable) or date of filing of the application.
vi) If no request for examination is made within the prescribed period the
application will be treated as withdrawn by the applicant [S.11B (4)]
viii) The request for examination in case of divisional application shall be filed
within 48 months from the date of filing or priority of the parent application
or within six months from the date of filing the divisional application,
whichever expires later. Request for divisional application shall be filed
only after filing request for the parent application to ensure the requirement
of section 16(3).
6.2.3 Request for Withdrawal: The applicant can, however, withdraw his
application at any time after filing the application but before the grant of a
patent by making a request to that effect in writing with prescribed fee under
entry No.23 of the First Schedule of the Patents Rules 2003. [S.11B (4) (i),
R. 26].
168
(d)A person who is interested in the commercial value of the invention can
request for examination and get the license for patent later after consultation
with the applicant.
(e)If the applicant wishes, he can withdraw the application before the end of 15th

Screening
169
After scrutiny of the documents, the lacunae, if any, in the application will
be communicated to the applicant in FER.
f) The examiner conducts novelty search to see whether the invention claimed in
any claim of the complete specification has been anticipated by any of the
following documents for the purpose of judging the novelty and inventive step
of the invention.
oi. Indian patent specifications published before the date of filing of the
application, but on or after 1st January, 1912 - [(S.13 (1)(a)] (Prior publication)
170
oii. Indian patent specifications which are filed before the date of filing of the
present case or claming a priority date earlier to the said date, but the publication
of that document was effected on or after the filing date (S. 13(1) (b) – (Prior
claiming)
g) For establishing novelty of the invention, the requirement holds that all the
features from the independent claim should be described in a single document.
When even a single feature is missing from the cited document, the claim may
be considered as novel. It is also necessary that all the features be described in
the same combination in the single document.
171
Type Description of Document

172
2) Where the request for examination has been received, the Controller shall refer
the application, specification and other document to the examiner in respect
of the application, ordinarily within one month from the date of publication or
request for examination, whichever is later [Rule 24 B (2)]
4) The Examiner shall make a report to the Controller on the above matters
ordinarily within a period of 1 month but not exceeding three months from
the date of such reference.
5) The Controller shall dispose the report of the examiner ordinarily within one
month from the date of the receipt of such report.
7) The time for putting the application in order for grant is 12 months from the date
of FER.
ii. In case, any other interested person files the request for examination, an
intimation of such examination of the application may be sent to such
interested person.
iii. If any of the objections require amendment of the application, specification or
drawings to ensure compliance with the provisions of the Act or the Rules, the
same will be communicated to the applicant along with the FER.
iv. The applicant will be allowed to carry out the necessary amendments of the
application, specification or drawings.
vi. The amended documents together with the specification will be examined
again in the same way as the original specification (S.13 (3)).
173
vii. The applicant will be given an opportunity of being heard, if he so requests,
when the examination report is adverse to him and he contests any of
objections or refiles his specification along with his observations regarding
amendments of the same (S. 14 & R.24 (B), R28). The request for such hearing
should made at least 10 days before the expiry date
viii)viii. There can be one or more correspondences after the issue of FER.
However, the time for meeting the objections and putting the application in
order for grant is 12 months from the date of issue of FER (S. 21(1), failing
which the application will be abandoned.
ix. Examination procedure carried out under section 12 and 13 shall not be
deemed in any way to warrant the validity of any patent, and no liability shall be
incurred by the Central Government or any officer thereof because of any such
examination or investigation or any report or other proceedings consequent
thereon.
6.2.10 Example: In 1999 (19) PTC 479 Registration of patent does not entitle any
presumption of validity in favour of patent in spite of investigation before its
registration—Patent Act, 1970—Section 12,13 & 64.
Held: Section 13(4) of the Patents Act provides that the examination and
investigations required under sections 12 & 13 shall not be deemed in any way to
warrant the validity of any patent, and no liability shall be incurred by the Central
Government or any officer thereof by reason of, or in connection with, any such
examination or investigation or any report or other proceedings consequent thereon.
Thus, grant of patent in any manner does not guarantee the validity of the patent.
Reference may also be made to the provisions of Section 64 of the Patents Act
which deals with revocation of patents. It provides that a patent whether granted
before or after the commencement of the Act, may, on the petition of any person
interested or of the Central Government or on a counter-claim in a suit for
infringement of the patent, be revoked by the High Court on the ground that the
subject of any claim of the complete specification is not an invention within the
meaning of this Act or that the invention so far as claimed in any claim of the
complete specification is not new having regard to what was publicly known or
publicly used in India before the priority date of the claim or to what was
published in India or elsewhere in any of the documents referred to in Section 13
or that the invention so far as claimed in any claim of the complete specification is
obvious or does not involve any inventive step, having regard to what was
publicly known or publicly used in India or what was published in India or
elsewhere before the priority date of the claim.

(b) Two or more applications for inventions cognate, additional fee required.
(c) The inventions disclosed in the specification filed with applications made in
the convention countries are not so related as to constitute one invention or to
a group of invention so as to form a single invention. The application should
therefore be divided into separate applications.
(d) The inventions disclosed in the specifications filed with applications made in
the convention countries are not so related as to constitute one invention or to
a group of invention linked so as to form a single invention but are cognate or
of which one is a modification of another accordingly, additional fees in
respect of applications should be remitted immediately.
When the application or specification or any other document filed does not
meet the requirements of the Act or the Rules , the Controller can refuse the
application for grant of patent by an order either suo-moto or after hearing
the party to the application when a request for hearing is requested. The order
of the controller is appealable before the Appellate board
The Controller can stay the proceedings towards the grant of patent till
requirements under the Act or Rules are met by the applicant to his
satisfaction by way of amendments in the application or specification or any
document, as the case may be. In case the applicant does not comply with the
requirements within the time as prescribed under Sec.21, he may refuse the
application.
4.14.1 When an application made by applicant claims more than one invention,
the applicant on his own or to meet the official objection may divide the
application and file two or more applications, as applicable for each of the
inventions. This type of application, divided out of the parent one, is called a
181
Divisional Application. The priority date for all the divisional applications
will be same as that claimed by the Parent Application (Ante-dating).
The High Court considered the following well settled propositions of law:—
The said divisional application was rejected by the Controller of Patents vide
his order dated 11.01.2007 u/s 15 of the Patents Act, 1970 (as amended).
In the parent case, the prima facie objection for plurality of distinct
inventions was raised by the Patent Office due to multiple sets of
independent claims.
182
accordingly they agreed to delete them. Thus, claims 1-6 only were allowed
in the parent case.
Therefore, the divisional application did not meet the requirement of Section
16 (3) of the Act.
Accordingly, the Controller of Patents ordered refusal to grant letters of Patent for
the aforesaid patent application No. 251/MUMNP/2005.
a) The application for patent may be post-dated to a date not later than six months
from the date of application on a request made by the applicant at any time before
the grant of patent along with the prescribed fee as given in first schedule.
However this provision will not apply if the application is deemed to be abandoned
183
patent granted would be effective. Thus post-dating the patent to 11-7-1989
appears to be illegal in view of the provisions of section 9(4) of the Patents Act
and the provisions of section 17 are subject to section 9.
Section 18.
(1) Where it appears to the Controller that the invention so far as claimed in any
claim of the complete specification has been anticipated in the manner referred
to in clause (a) of subsection (1) or sub-section (2) of section 13, he may refuse
the application unless
the applicant—
(a) shows to the satisfaction of the Controller that the priority date of the
claim of his complete specification is not later than the date on which
the relevant document was published; or
(a) the applicant shows to the satisfaction of the Controller that the
priority date of his claim is not later than the priority date of the
claim of the said other specification; or
(a) that the invention so far as claimed in any claim of the applicant's
complete specification has been claimed in any other complete
184
specification referred to in clause (a) of sub-section (1) of section 13;
and
(b) that such other complete specification was published on or after the
priority date of the applicant's claim,
then, unless it is shown to the satisfaction of the Controller that the priority date
of the applicant's claim is not later than the priority date of the claim of that
specification, the provisions of sub-section (2) shall apply thereto in the same
manner as they apply to a specification published on or after the date of filing of
the applicant's complete specification.
Rule 29:
(1) When it is found that the invention so far as claimed in any claim of
the complete specification, is claimed in any claim of any other
specification falling within clause (b) of sub-section (1) of section 13, the
applicant shall be so informed and shall be afforded an opportunity to
amend his specification.
6.3.1 If the invention is anticipated by prior publication as per S.13 (1) (a) or
S.13(2), the Controller may refuse the complete specification unless the applicant
shows that the priority date of his claim is not later than that of the cited document
or amends his complete specification to the satisfaction of the Controller. [S.18 (1)
& Rule 28]
6.3.2 If the invention is anticipated by prior claiming as per S.13 (1) (b), the
Controller may direct that a reference to that other specification be inserted in the
applicant’s specification by way of notice to the public unless the applicant shows
that the priority date of his claim is not later than that of the claim of cited
document or amends the specification to the satisfaction of the Controller. (The
Controller need not consider the validity of the prior specification when directing
such a reference) [S. 18(2) & Rule29, 30, 31]
185
If the invention is anticipated by prior publication as per S.13(1) (a) and the other
complete specification was published on or after the priority date of the applicant’s
claim, the remedy for the anticipation by prior claiming as explained above will
equally apply to this case (S.18(3)).
Section 19:
(1) If, in consequence of the investigations required under this Act, it appears to

OPPOSITION PROCEEDINGS TO GRANT OF PATENT
(1): Where an application for a patent has been published but a patent has not
been granted, any person may, in writing, represent by way of opposition to the
Controller against the grant of patent on the ground -
a.(a)that the applicant for the patent or the person under or through whom he
claims, wrongfully obtained the invention or any part thereof from him or
from a person under or through whom he claims;
iii) Provided that the ground specified in sub-clause (ii) shall not be
available where such publication does not constitute an
anticipation of the invention by virtue of sub-section (2) or sub-
section (3) of section 29;
194
e.(e)That the invention so far as claimed in any claim of the complete
specification is obvious and clearly does not involve any inventive step having
regard to the matter published as mentioned in clause (b) or having regard to
what was used in India before the priority date of the applicant’s claim;
f.(f) That the subject matter of any claim of the complete specification is not
an invention within the meaning of this Act, or is not patentable under this Act
g.(g)That the complete specification does not sufficiently and clearly describe
the invention or the method by which it is to be performed
h.(h)That the applicant has failed to disclose to the Controller the information
required by section 8 or has furnished the information which in any material
particular was false to his knowledge
i.(i) That in the case of convention application, the application was not made
within twelve months from the date of the first application for protection for
the invention made in a convention country by the applicant or a person from
whom he derives title
j.(j) That the complete specification does not disclose or wrongly mentions the
source or geographical origin of biological material used for the invention
Rule 55:
195
patent or accepting the representation and refusing the grant of patent
on that application, ordinarily within one month from the completion of
above proceedings
7.1.1 Grounds for Pre-grant Opposition by way of Representation u/s 25(1) are
summarized as follows:
a) Wrongfully obtaining
No ground other than the statutory grounds as above can be taken for
opposing the Grant of Patent under section 25(1)
2. The Controller shall not grant the patent before the expiry of 6 months from
the date of publication under section 11 A. Therefore, a person should try to
file such representation within the assured period of 6 months from the date of
publication under section 11 A.
196
4.The Controller shall consider the representation only after a Request for
Examination for that application has been filed.
6.The applicant shall, if he so desires, give reply to that representation along with
his statement and evidence, if any, in support of his application within three
months form the date of the notice.
7.The Controller shall consider the statement and evidence filed by the applicant
and may either refuse the grant of patent or ask for amendment of the complete
specification to his satisfaction before the grant of patent.
8.After considering the representation and submission made during the hearing, if
so requested, the Controller shall proceed further simultaneously, either
rejecting the representation and granting the patent or accepting the
representation and refusing the grant, ordinarily within one month from the
completion of the above proceedings.
Example1:
3. Applicant filed the reply statement with evidence on 25/07/2005 and also
asked for hearing.
4. The Controller conducted the hearing and considered various grounds for
opposition in the light of submissions by both the parties and concluded as
follows:
The title compound commercially, called imatinib mesylate, which has been
claimed by the applicant is already known in the US Patent No.5521184
(1993 Patent) The 1993 Patent discloses methanesulphonic acid as one of the
197
salt –forming groups and also states that the required acid additions salts are
obtained in a customary manner. Further ,claims 6to 23 of the 1993 Patent
claim a pharmaceutically acceptable salt of the base compound.. Another
Document, “Nature Medicine” (May 5, 1996) also describes the title
compound. Also the compound , imatinib mesylate salt inherently existed in
the β-crystalline form, which is most stable form of the salt. This fact is also
clear from the results of laboratory experiments conduced by two reputed
government institutions, namely, Indian Institute of Chemical Technology,
Hyderabad and Indian Institute of Technology, Delhi, . Hence, the claims of
the present application for the product and process in respect of the title
compound stand anticipated by Prior Publication
Since the 1993 Patent disclosed the free base of the base compound, it was
obvious for a person skilled in the art to prepare the corresponding
pharmaceutically acceptable salts. The studies by the two laboratories
mentioned above clearly demonstrated that the salt prepared using teachings
and instructions of the 1993 Patent inherently exists in β-crystalline form.
Hence the product claims are obvious over the aforesaid disclosure in the prior
art.
iii) Non-patentability u/s 3(d) of the Patents Act: As per section 3(d), any
salt or polymorph or derivative of the known substance is not patentable
unless such salt or polymorph or derivative shows enhanced efficacy of the
substance. As regards efficacy, the patent specification itself states that,
wherever β-crystals are used, the imatinib free base or other salts can be used.
The affidavit submitted by the technical expert on behalf of the applicant
demonstrated that the relative bioavailability of the free salt with that of β-
crystal form of imatinib mesylate differ only by 30% and accounted this
difference to their solubility in water. Thus, the present specification does not
bring out any improvement in the efficacy of the β-crystal form over the
known substances ; rather its states that the base compound can be used
equally in the treatment of diseases or in the preparation of pharmacological
agents wherever the β-form is used. Thus, the product claim amounts to a
mere discovery of the new form of the known substance. Hence, the subject
matter of this application is not patentable u/s 3(d) of the Patents Act, 1970,
as amended by Patents (Amendment) Act, 2005.
The application filed in India has claimed the Swiss priority dated
18/07/1997, but Switzerland was not an convention country on that date. It
became the convention country only in September,1998. Hence, no priority of
Swiss application can be claimed in respect of the present application.
Decision:
In view of the above findings and arguments made by both the parties
during the hearing , the Learned Controller ruled that the Patent Application
no.1602/MAS/1998 cannot proceed for grant of patent.
198
Example 2:
It was held that “the selection of particular range of ingredients from the
ranges already known prior art in this case cannot amount to establish the
inventive step and The variations in the amounts of the known ingredients
appear merely workshop improvements achieved by a person skilled in the art
without performing any substantial experiments and can not be said a
technical advancement of an existing knowledge which is required by the
definition of the "inventive step" as mentioned in section 2(l)(ja) of the Patents
Act, 2005.” and for the ground u/s 3(e) that
“The existence of already known characteristics of composition with known
ingredients cannot be termed as synergy among the ingredients of claimed
composition”

7.2.1 Grounds for Post-grant Opposition u/s 25(2) are summarized as follows:
a) Wrongfully obtaining
204
e) Obviousness and lack of inventive step
1. Any interested person can oppose the grant of Patent under section 25(2) by
giving a notice to the Controller, within one year form the date of publication
of grant of a patent in the official journal.
2. The notice of opposition shall be made in Form 7 and sent to the Controller in
duplicate at the appropriate office along with the prescribed fee given in first
schedule. The notice of opposition shall be accompanied by a written
statement (in duplicate) stating out the nature of opponent’s interest, the facts

to the patentee a copy of the statement and the evidence, if any, filed by him
along with the notice of opposition.
3. The Controller shall notify the patentee regarding the filing of the opposition.
4. Opposition Board: On receipt of the notice of opposition under rule 55A, the
Controller, by order, shall constitute an Opposition Board which will consist of
three examiners as members, other than the examiner who has examined the
application. The Controller shall nominate one of the members as the
chairman of the Board.
5. If the patentee desires to contest the opposition, he shall send the reply
statement at the appropriate office giving grounds for contesting the opposition
and evidence, if any, in support of his case within a period of 2 months from
the date of receipt of a copy of the written statement and opponent’s evidence
205

statement and evidence. (Rule 58).
6. If the patentee does not desire to contest or fails to send his reply and evidence
within the specified period as above, the patent shall be deemed to have been
revoked [Rule 58 (2)].
7. The opponent may file the evidence in reply within one month form the date
of delivery to him a copy of reply statement and the evidence by the patentee;
such a reply evidence by the opponent must be strictly confined to the matters
in the patentee’s evidence (Rule 59). Also, the opponent shall deliver to the

may require members of the Opposition Board to be present in the hearing.
11. If any party desires to be heard he shall make a request to the Controller along
with prescribed fees given in first scheduled.
7.2.3 Cases reported for the post-grant opposition held on various grounds of section
25 (2) of Indian Patents Act are as mentioned below :
Example: 1
206
of the final product or process or merely involved in carrying out experiments
does not mean that they are inventors. The inventor for the purpose of Patent law
is the actual deviser of what is being claimed. So the opponent failed to prove this
ground. (Wrongfully Obtaining)
Example 2 :
It was held that the ingredients recited in the principal claim have a very
specific and narrow range of proportions, which are not taught by cited
documents. Cited document also do not teach how to obtain the right balance of
salt and glycerol in order to avoid a soap which is too hard or too soft and also
do not mention about balancing quantities of glycerol or salt against the
quantities of total fatty matter. The alleged invention mentions the prior art,
problems associated with it, results of various experiments, and best method of
working examples. Considering all these factors it was judged that the opponents
had failed to establish the above grounds and opposition was rejected
Example3 :
In the matter of Patent No.- 183458 (454/BOM/1998); the invention related to "A
process for the preparation of a therapeutic Anti-inflammatory and analgesic composition
containing Nimesulide for use transdermally" Opposition was lodged on the ground of
prior publication Under Section 25 (1)(b), prior public knowledge Under Section
25(1)(d), Obviousness Under Section 25 (1)(e), not an invention within the
meaning of the Act Under Section 25 (1)(f).
Comparison of the alleged invention 183458 with the Sri Lanka's Patent 11012 &
Nigerian Patent RP 12829 clearly shown that it does not pass the test of the novelty It is
sufficient to destroy the novelty of the claimed process that this process and the
known process are identical with respect to the starting material and reaction condition
since process as identical in these features must inevitably yield identical products. It was
held that in view of the cited Srilanakan & Nigerian Patents the alleged invention
stand anticipated as cited document has disclosed the invention or disclosed
information in such a way as to make it part of the state of the art.
Grant of Patent was refused on the above grounds.
Example 4 :
In the case of Gujrat Reclaim & Rubber Products Ltd V Kamani Metallic Oxides Ltd1983
(3) PTC 105 (PO), a notice of opposition to the grant of a patent to M/s. Kamani Metallic
Oxides Ltd., Bombay, for their patent No. 145917, application number 43/BOM/1976 ,
for an invention titled “A process for separation of rayon or nylon fibres from cracked
207
waste tyres and an apparatus thereof” was filed by M/s. Gujarat Reclaim & Rubber
Products Ltd., Bombay, on 15-6-1979 having regard to the prior art citations JP-
8059512 published on 05/03/1996 and US Patent 5,885,617 published on
23/03/1999.
Opposition to grant of patent was on the grounds of prior publication, prior public
knowledge and prior public use, lack of inventive step and insufficiency of description .
It is held that the opponents being engaged in the manufacture of reclaimed rubber in
which cracked waste of automobile tyre and such other rubber waste are used and have a
manufacturing unit, the opponent are held as 'persons interested' as stipulated in section
25 of the Act. Opponents deposed in support of the opposition that the types of standard
machineries used for carrying out the process of separating the rubber particles from
fibrous materials and the alleged invention disclosed in the applicants' complete
specification has been anticipated by the Exhibits. In the circumstances, a rubber
technologist would know its application to cracking of rubber for separation of fibre
from rubber and particularly from waste tyres and in fact it has been used for said
purpose for many years.
Applicants contested all the arguments of opponents and argued that the opponents have
confused the issue by saying that something used in some point of time in the
reclamation industry has been claimed by the applicants. He said that applicants'
invention lies in the process and apparatus for the separation of fibre from cracked tyres
waste i.e. a narrow aspect of dealing with the wider subject of rubber reclamation. So far
as the document relating to reclaim from natural and synthetic rubber scrap is concerned,
the original which was a confidential document ,and therefore, it has not been published
and which is not open to public. On a scrutiny of this document the court observed that
the disclosure related to the general process for reclaiming of rubber from natural
and synthetic rubber scrap and slow grinder discs for precracking.
The process consisting of three stage viz. cracking, fabric separation and grinding the
details given there are applicable generally in a rubber reclaiming process. The
invention disclosed in the applicants' specification related to an improved process for
the removal of fibre from cracked automobile tyre wastes i.e. the second aspect of the
above said three stages process. The steps involved in the process claimed in the
complete specification are not found in the said document. No details have been given
in the publication about the process and apparatus for removal of fibre from tyre wastes,
as has been disclosed in the applicants' specification. Accordingly, the disclosure
contained in the said document, even if it is considered to have been published before
the priority date of the applicants, the application does not anticipate the applicants'
process and apparatus..
Hence, the opponents failed to establish the ground of prior publication. Similarly the
opponents also failed under the ground of prior public knowledge and prior public use as
the documents relied upon by the opponents are not relevant as they do not anticipate the
applicant's invention. The opponents failure to provide any other evidence in support of
their contention as to obviousness and lack of inventive step failed them on this
ground also. Hence, there being no force in their other grounds of opposition, the
opposition is dismissed .
It was held for the ground under section 2 (1)(j) that “the selection of particular
range of ingredients from the ranges already known in the prior art in this case
208
cannot amount to establish the inventive step and variations in the amounts of the
known ingredients appear merely workshop improvements achieved by a person
skilled in the art without performing any substantial experiments and can not be
said a technical advancement of an existing knowledge which is required by the
definition of the "inventive step" as mentioned in section 2(1)(ja) of the Patents
Act, 2005.”
Example 5 :
In the matter of Thermax Private Limited v. Deccan Sugar Industries, (1987 PTC
137.) Opponents in their written statement of opposition made certain allegation
which can be construed to be in support of this ground of opposition, namely,
unfair description. The opponents in their written statement of opposition at page 3
para (j) thereof made certain allegations about description wherein they alleged
that the specification contained several process variations. What is stated by the
opponents during hearing can be construed as an implication of their written
statement. Further, during hearing, the applicants were at liberty to deal with each
of the opponents' allegations separately and elaborately which they have not done.
The opponents clearly proved the deficiencies in the description. Hence, the
ground of unfair description is established. Opponents have therefore succeeded in
this ground.
Example 6 :
In the matter of Jagadish Mohanlal Joshi V/s. Ghodavat Pan Masala Products P.
Ltd. Patent No. 188090 (application no. 166/BOM/1997) Among other grounds,
the “insufficiency of description” was a ground for opposition under Section
25(1)( g), citing “If the applicant does not give prior art details in the specification
it would mislead the controller and the public, mouth refreshing preparations with
tobacco and without tobacco are known in the art, and the applicant is not entitled
for a patent unless he shows that his process is an improvement over the earlier
process. For this purpose, when 47 RPC 289 was cited submitting that the patent
should justify clearly why a particular selection is made, the applicant submitted
that the “Non disclosure of prior art does not result in insufficiency of description,
the disclosure should enable the skilled person to exercise the invention which the
applicant did, and further he deemed the impugned invention was a selection
patent”. The Controller agreed with the applicant’s submission and upheld the
patent and dismissed the opposition.

After the hearing it was concluded that that teachings of the exhibits were
either not pertinent or insufficient to prove the grounds and the opponents
could not prove any of the above grounds of opposition .
Applicants made amendments in the description and claims at the time of
hearing to make their point clear and to overcome the opponents allegations.
As all the amendments were within the scope of invention and have support in
the description, these amendments in the claims were allowed

The proceedings of the opposition took place to decide whether the applicant's
devices involve any inventive step and the opponents lead any evidence as to
patentability The opponents have challenged the alleged application for Patent No.
179304 on the grounds of Section 25 namely, anticipation by prior publication- clause
(b) , anticipation by prior claiming - clause (c), prior public knowledge or public use-
clause (d) & obviousness and lack of inventive step- clause (e)

(Ex-C3). 5th July, 1983 & 5,038,974 dated 6th August, 1991.
Proceedings:
It can not be concluded that the cited documents on Patents and Designs can
establish anticipation by prior publication, as by combining the integers of the
mosquito repellent from the cited patent & design documents is not resulting the
identical article as produced by the alleged invention.
No document has been produced or referred by the opponents regarding any claim
made by the applicants containing a subject of a claim of earlier priority date in a
complete specification published after the priority date of applicants' claim. The
opposition therefore can not stand based on the ground of prior claiming.
While considering ground under Section 25(l)(e) i.e. obviousness and the lack of
inventive step, the Tribunal considered and analysed the difference between
cited documents and the opposed specification to have any relevance regarding
obviousness and lack of inventive step
The device 'Mosquito Repellent' under the brand name of 'Good Night' is under
public knowledge and use for more than a decade. The Exhibit Ex-C2 & Ex-C3
reveal that the cordless mosquito repellent having press fit detachable top &
bottom portion with arrangement of insertion of mat on heater assembly and
twist-n-turn i.e. rotatable two pinned plug fitted with the device, manufactured and
marketed by Transelektra Domestic Products Private Ltd. were under public
knowledge and use much earlier than the date of the alleged application for Patent
No. 179304. For more than a decade the rotatable plug through 90 degree is under
public knowledge & use in many domestic electrical appliances and the press fit
arrangements are under public knowledge and use even much more than a decade.
The press fit arrangement of the top and bottom cover as depicted in Unit (iv) in
paragraph 2 wherein the projections of the top cover being press fitted with the
corresponding grooves formed on the inside face of bottom cover, is a mere
workshop modification. Supposing that in the application for patent in question
there is a difference with the cited documents in respect of the matter wherein the
plug being adopted in a detachable and rotatable manner by providing on the plug
rear portion with a integrally formed tubular portion having radially extending
flanges as narrated in feature (v) of the alleged application, even in that case it is
mere a workshop modification.
The Applicants' counsel have stated during hearing that the alleged device has
produced achievements (1) Maintaining of constant temperature of 150o C (2) can
easily assemble and disassemble (3) is a compact and can be conveniently used
without the necessity of any extendable cord (4) is a safer construction (5) give a
regulated release of active material by regulating temperature at 150o C.
All the above stated achievements of the alleged application have been found
and claimed in the cited US documents. In the above background this Tribunal
211
find that the alleged application has its integers (i) to (v) as narrated in paragraph 2
anti by combining one feature of an earlier specification with another earlier
specification and so on to secure no advantage other than addition of their
respective merits. The Tribunal therefore concluded that the alleged application
No. 179304 titled "A Mosquito/Insect Repellent Device" is obvious and clearly
does not involve any inventive step.
The grant of patent was therefore refused.

In the matter of M/s. Crompton Greaves Ltd. Mumbai (Applicant)Vs. M/s. Bharat
Heavy Electricals Ltd. Hyderabad (Opponent) Patent application No. 184657
(221/BOM/96)
This is an opposition under Section 25 of the Patents Act, 1970 to the grant of Patent
to M/s. Crompton Greaves Limited, Mumbai on their application for Patent No. 184657
(221/BOM/1996) dated 19th April, 1996 . The invention related to "A single phase
traction transformer for AC electric locomotive and a method of manufacturing the
same".
Under the ground of prior publicly known or publicly used in India under
Section 25(l)(d), the opponent submitted that they are in the field of designing and
manufacturing traction transformer and developed traction transformer or 3900
KVA in the year 1974. The opponent has supplied more than 600 single-phase
traction transformer of 3900 KVA to Indian Railway against their various
purchase orders prior to their Patent Application No. 184657 after approval of
prototype design from Indian Railway (RDSO). BHEL (Opponent) was the first to
supply 5400 KVA of traction transformer to Indian Railway.
It was held by the Controller that the ground under section 25(1)(d) that the
invention was publicly known or publicly used in India was not established by the
opponent – since the photo copies submitted by the opponent state mainly the
terms and conditions of a contract to supply 3900 KVA & 5400 KVA traction
transformers. The photocopies of work order did not define any constructional
features of the traction transformer. Only by stating that we are the first in the field
of manufacturing the applicant company cannot be stopped from obtaining a patent
unless the opponents establish that they are manufacturing an identical product.
Example 10 :
In case of Patent No. 184656 (Patent Application No. 221/BOM/96) the opponents
have submitted on the ground of obviousness that the alleged invention is obvious
mechanical equivalent of what been known prior to the date of the impugned
application. The opponent pleaded that transformer technology is known in the art
and claims as worded do not have inventive steps. The opponent submitted that
simply stating that the steps and features involved in the claimed invention are
obvious is not sufficient without disclosing any prior art which would make the
invention obvious to a person skilled in the art. The Controller held that when the
212
“invention is obviating certain drawbacks of the conventional traction transformer,
it cannot be said that the invention is obvious” in absence of relevant prior art.

This is an opposition to the grant of a patent under Section 25 of the Patents Act,
1970 for Patent No. 151977 of M/s. Jaya Hind Industries Limited (Applicants)
for “External Rotor Assembly for a Magneto”
The opponent M/s. Scooters India Limited, filed a notice of opposition against the
grant of a patent on the above application on 12th January, 1984. The case was heard
on 30th June, 1986.
Grounds of opposition were Prior publication section 25 (1) (b) , Prior public
use and prior public knowledge section 25 (1) (d), obviousness and lack of
inventive step section 25 (1) (e), Not an invention or not a patentable invention
section 25 (1) (f) insufficiency and clarity of description section 25 (1) (g)
In view of the findings in consideration of all matters stated in the written statement,
reply statement and evidence as well as the arguments furnished by the opponents and
applicants during the hearings and all the circumstances of the case, it was concluded
that the opponents have not proved the ground of prior publication and prior public
knowledge and have also not submitted any evidences to the fact that the
invention is obvious. Therefore, the opposition filed by the opponents M/s. Scooter
India Limited on application No. -151977 is dismissed

An Application for patent for an invention entitled 'A method for making a plant
growth nutrient/stimulant' was filed by Hindustan Lever Limited. The acceptance of the
application was notified in the Gazette of India part III, Section 2 dated 14-12-1982 after a
serial number, 150203 was accorded to it.
The invention relates to “A method for making a plant growth nutrient/stimulant which
comprises subjecting plant waxes like rice bran wax, camauba wax or sugarcane wax to
a step of saponification obtain a mixture of saponfied and non saponified matter,
whereafter the non-saponified matter is separated and recovered from the said mixture
by selective extraction is an organic solvent as the said plant growth nutrient/stimulant,
and optionally converting said nutrient/stimulant into a stable aqueous emulsion in a
conventional manner.
The alleged method consisted of only two steps and an optional step namely subjecting
plant waxes like rice bran wax, camauba wax or sugarcane wax to a step of
saphonification to obtain a mixture of saphonified matter is separated and recovered
from the said mixture by selective extraction in an organic solvent as the said plant
growth nutrient/stimulant, and, optionally converting said nutrient/stimulant into a stable
aqueous emulsion in a conventional manner

In the case of Abid Kagalwala v. Edgar Haddley Co. Pvt. Ltd. (1984 PTC 234) for
an invention relating to 'An improved Electrical Switch', it was held that the
Applicant has not described as how the use of a resistor in the circuit would be
able to eliminate the use of an amplifier. Also the invention has not been properly
and clearly described and will not function in the way claimed by the applicants.
Hence the patent grant was refused.
Example 16
214
In an opposition for the patent no. 194085 [AIR 1961 GUJARAT 120 at Page
125] grounds of opposition included prior disclosure and lack of inventive step.
For the prior disclosure, it was held that “Where prior disclosure is relied upon, it
is necessary to point to a clear and specific disclosure of something which can be
fairly stated to be the invention of the patentee/applicant. If it is something which
is said to be like the patentee's/applicant's invention, there should be a description
of its use and the manner in which the patentee/applicant intends it to be used. It
is not open to take a packet of prior documents, and, as it were, by means of some
process of putting a puzzle together, produce what is said to be a disclosure in the
nature of a combination of the various elements which have been contained in the
prior documents” and that “To anticipate a patent, a prior publication or activity
must contain the whole of the invention impugned, i.e. all the features by which
the particular claim attacked is limited, for the anticipation must be such as to
describe, or be, an infringement of the claim attacked.”
[M/s. Teva Pharmaceuticals Industries Ltd. vs. M/s. Torrent Pharmaceuticals Ltd.]
Example 17
The ingredients recited in the principal claim have a very specific & narrow range
of proportions, which are not taught by cited documents. Cited document does not
teach how to obtain the right balance of salt & glycerol in order to avoid a soap
which is to hard or too soft. Also in cited documents there is no mention of
balancing the quantities of glycerol or salt against the quantities of total fatty
matter. The present invents offer solution to the problem by retraining glycerol
produced during specification of triglycerides in the soap bar composition
rather than removing it. Also present invention obtained surprising result that the
narrow range of total fatty matter, electrolytes of glycerol been taken together in
particular combination by applying combination of three steps lead to soap
containing glycerol which has acceptable physical proportion. Alleged invention
mention prior art, problems, associated, results of various experiments, all
essential components, best method by way of working examples.
Opponent failed to establish the above grounds Hence, the patent proceeded for
grant

applicants being a society registered under the Act, it enjoys the Status of legal entity
and as such is capable of suing or being sued as well as capable of entering into a
contract and accordingly the preliminary objection raised by the Opponents is rejected.
As regards grounds of opposition as stated in clauses (a) to (h) of Sub-section (1) of
Section 25 of the Act, it is held that the Opponents have failed to establish ground (a)
regarding wrongful obtaining of invention. Similarly, the Opponents having failed to
substantiate grounds (b), (c), (d) and (e) by way of documentary evidence, the same are
also rejected. As regards ground (f), it is held that since subsequent claims do not have
any independent status and have to be construed in conjunction with claim 1 and the
opponents having failed to analyse claim 1 of the Applicants, this ground also fails.
Regarding ground (g) relating to unfair description, the opponents having been successful
in establishing the deficiencies in the description, it is ordered that no patent should be
granted to the Applicants
Example 19
In the matter of Patent No, 119964 between M/s Colgate Palmolive & Co. vs. M/s
Hindustan Lever Limited; titled “Process and composition for removing stains from
fabrics” Applicant raised the objection that the opponent have merely referred to three
Indian Prior Patents by numbers without showing how the claims of any of them
anticipate the invention of the opposed application. Controller held that “a mere
reference is sufficient as it is my duty to see the matters contained therein and
thereafter to take or reject any or all of them if they relate to something not
appropriate in the proceeding”
Example 20
In the matter of Patent No.120345 between Ashok Ganesh Joshi vs. Harbans lal
Malhotra & Sons Pvt. Ltd. For an invention titled “ Improvements in or relating to
blades for razor and the like instruments.” an opposition to the grant of patent
filed taking grounds of prior claiming, unfair description and prior public
knowledge and user in India of section 9 of Patents Act’ 1911 and after the
implementation of Patent Act’1970, it was considered under the corresponding
grounds of Section 25 i.e. 25(1)(b)(i), 25(1)(c), 25(1)(d) and 25(1)(g). The
Controller held that :
Criteria for “Criteria for prior claiming
In order to establish prior claim it must be shown that the subject matter of a claim in
the applicants specification forms the subject matter of a distinct claim in the cited
specification. It is not sufficient if the claim is merely comprehended in the subject
matter of a claim in the cited specification. This follows from the wording of the
section. The comparison must be made between (and limited to) the claims in the
relevant specifications that is to say, it does not suffice to support an objection under
section 25(1)(e) to show that what is claimed in the application as a subject matter
for protection is to be found somewhere comprehended or described in the earlier
216
specification. For the purpose of justifying a finding of prior claim one must find a
distinct claim in the earlier specification, which, as a matter of substance, is
equivalent to the claim in the applicants’ specification. Before claiming to the
conclusion that an invention is claimed in an earlier specification. That invention
must be found to be distinctly claimed in the earlier specification. This principle
applies to chemical selection patents as well as to patents for mechanical
combination. (Para 7, Page 160, 161)
Taking up next the ground of ‘unfair description’, I would point out that this ground
would have a considerable effect in an opposition proceeding if it be clearly
established that the specification contains description and claims of the alleged
invention which is ambiguous, misleading or cannot be clearly understood. From the
full written statement, and the evidences submitted by the opponents it would appear,
on the other hand, that what has been understood by the opponents as the alleged
invention is fully consistent with the actual alleged invention that has been presented
by the applicant in the specification. Furthermore, the description and the claims do
not appear to be ambiguous or vague in any way and the invention as has been alleged
in the claims can be clearly understood by any man in the art. So there does not
appear to be much weight in this ground of ‘unfair description’ and I have to conclude
that the opposition has nothing much to gain on this ground also.
Example 21
5. In the matter of Patent No, 124171 granted for “Improved traction and
hoisting apparatus” and opposed by M/s Pulling and Lifting Machines Private Limited
under section 9 of Patents Act’ 1911 and after the implementation of Patent Act’1970,
it was considered under the corresponding grounds of Section 25 i.e. 25(1)(d) and
25(1)(g).
“In an opposition proceeding under section 25 of the Act the responsibility of the
opponent does not appear to end with the levelling of certain allegations only against
217
the applicant’s invention but he has the duty under the Act to take adequate interest to
diligently pursue the opposition and to establish the grounds he relied upon.
However, for not furnishing necessary particulars as aforesaid I am unable to consider
the merit of this ground on the basis of what has been merely referred to in the written
statement of opposition by the opponents. I hold that the opponents have failed to
discharge their onus to establish the ground of “prior public knowledge or public user
in India” taken by them”. (Para 5, page 179)
Example 22
In the matter of Patent No, 146120 ,the petitioners have prayed to the Controller
to direct the opponents to withdraw the evidence or amend the same since the
drawings annexed to his affidavit were incorrect and not true and that are
accordingly the evidence filed by the opponents under rule 38 is false and further
to enable the applicants to adduce their evidence under rule 39. The Controller
held that: I cannot force them to amend the affidavits simply because the
applicants have doubt on the drawings annexed to the affidavits filed by the
opponents. The controller has full power either to reject or to accept the affidavit
fully or partly after the final hearing of the parties but cannot force the party to the
proceeding to amend the affidavit. I do not agree with applicant counsel’s
arguments that the Controller is empowered under section 77 and rule 113 to force
the party to proceeding to amend their affidavit on merely a doubt raised by the
applicants. The expression “any other matter’ under section 77(1)(h) means any
other matter prescribed under the Act or the Rules allied to what are given in
clauses (a) to (g) of sub-section (1) of Section 77. It cannot mean any other matter
not prescribed under the Act or the Rules or matters not allied to such as specified
in clause (a) to (g) of Section 77(1). Similarly the expression “to perform an act,
file a document or produce evidence” of Rule 113 has to be read as allied matters.
One cannot assign different meaning to each expression. Under Rule 113, if the
Controller is of the opinion that it is necessary, then only he will ask the party to
perform an act, file a document or produce evidence. Since the Controller cannot
go into the merits of the case at this stage, he cannot form any opinion. Therefore,
the question of asking the opponents to perform an act does not arise. Further
since I have already said that the expression “to perform an act” is an allied
expression to file a document or to produce evidence, it cannot mean that the
Controller can force the party to amend the evidence. As regards applicant
counsel’s argument under the Civil Procedure Code, I would state that the
Controller is technically not a Court and the C.P.C. is not applicable before him
(A.I.R. 1934 Cal. 725).
Example 23

rigid surface while its area is being measured and the endless conveyor and two end
rollers around which said conveyor passes in the prior art of the said French
specification have been replaced by two guide rollers and a slotted table in the present
invention. The use of a table in conjunction with such machine has already been
disclosed in the extract of Turner Machine …….It is obvious that a table, if used in
such a machine has necessarily to be slotted or perforated to allow light rays from the
light source to pass there through so as to fall on the light sensitive devices located on
the opposite side, otherwise Light sensitive devices will not operate when a skin or
any opaque object passes over such table…………. The applicant has not made any
scintilla of invention in the provision of electronic circuits claimed in the statement of
claims, as the same has been admitted in the specification to be known in the art.

Example 25
In the matter of Patent No. 149901 and in the matter of Substitution of name
of the opponent during opposition under section 25, the application was
opposed by Board of Tea Research Institute of Ceylon, Sri Lanka &
Competent authority the Govt. of Sri Lanka successor of business undertaking
of Colombo Commercial Company (Engineering) Ltd., Sri Lanka. The Board
of Tea Research Institute of Ceylon was amalgamated with Sri Lanka tea
Board by virtue of Law no. 14 of 1975 and all the rights and obligation
including property of the Tea Research Board Institute should be deemed to
be the right and obligation of the Board. However the provision of this law
according to the notification was to come into operation on such date as may
be appointed by the Minister and published, There was no proof on the record
to prove that any date has been appointed by the Minister in order to
219
operationalise the said law. Therefore Controller held that the name of Board
of Tea Research Institute of Ceylon can not be substituted by its successor
namely Sri Lanka Tea Board. It was further held (the Terrel on Law Patent at
page no. 171 ) that “ A different opponent can not be substituted by
amendment after the expiry of the opposition period even if he acquires and
interest from the original opponents . further it is intended to limit opposition
proceedings to persons who possess necessary interest in the period laid down
for opposition and also excluding a person who only acquired such interest
subsequently even if it is acquired from a person who had it an used it at the
time lodging opposition and therefore substitution of opponents asked for is
not legitimate.

Section 26;
(1) Where in any opposition proceeding under this Act the Controller finds that-
220
that ground, he may, on request by such opponent made in the
prescribed manner, direct that the patent shall stand amended in the
name of the opponent;
(b) a part of an invention described in the complete specification was so
obtained from the opponent, he may pass an order requiring that the
specification be amended by the exclusion of that part of the
invention.
2)(3) Where an opponent has, before the date of the order of the Controller
requiring the amendment of a complete specification referred to in clause (b)
of sub-section (1), filed an application for a patent for an invention which
included the whole or a part of the invention held to have been obtained
from him and such application is pending, the Controller may treat such
application and specification in so far as they relate to the invention held to
have been obtained from him, as having been filed, for the purposes of this
Act relating to the priority dates of claims of the complete specification, on
the date on which the corresponding document was or was deemed to have
been filed by the patentee in the earlier application but for all other
purposes the application of the opponent shall be proceeded with as an
application for a patent under this Act.
Rule 63A:
Request made under section 26(1);
Request under section 26(1) shall be made on Form 12 within three months
from the date of the order of the Controller and shall be accompanied by a
statement setting out the facts upon which the petitioner relies and relief he
claims.
Where the Controller refuses the application on the ground of wrong full obtaining,
as a result of proceedings under section 25(2) clause (a), and revokes the patent on
this ground, a request can be made by the opponent in Form 12 along with the
prescribed fee and in the prescribed manner to allow the patent in the name of the
opponent. The controller , upon such request may direct the application to proceed
in the name of the opponent with the benefit of priority date attached to the
application and order for such an amendment.
221
him has been filed before the order of the controller u/s 26(1) (b) for amendment
of patentee’s specification on the grounds of obtaining and such application is
pending. In such a case, the controller may treat the application and specification
filed by opponent containing the whole or apart of invention so excluded from
applicant’s (patentee’s) specification as opponent’s application with the same
priority date as the earlier application; but for all other purposes the opponent’s
application will be treated as an independent application under the Act.

later than twelve months after the opening of the exhibition (notified by the
Central Government) where the invention is first displayed and published
by the applicant or used with his consent, it will not be deemed as anticipated.
The use of the invention (so displayed) by an unauthorized person during the
period of exhibition also will be deemed as non-anticipation.
(d) The description of the invention in a paper read by the true and first
inventor or its publication with his consent in the transactions before a
learned society also does not constitute anticipation, if the application is
made within the period of twelve months.

the Controller shall not do that act until the fee has been paid.
(3) Where a fee is payable in respect of the filing of a document at the patent

10.2 Grant of Patent: (Section 43)
The patent is granted when the applicant for patent put the application in order
for grant under Section 21 of the Act and when there is no pre-grant
representation within the stipulated period or when the pre-grant opposition
has been disposed of in favour of the applicant. After a patent is granted in
respect of applications made under Section 5(2) of the repealed Act, the patent
holder shall only be entitled to receive reasonable royalty from such
enterprises which have made significant investment and were producing and
marketing the concerned product prior to the 1st day of January 2005, and
which continue to manufacture the product covered by the patent on the date of
grant of the patent and no infringement proceedings shall be instituted against
such enterprises.
10.3 Deletion of the claims at the time of sealing under section 43 and method of
tagging of animal ear not an invention under section 2(1)(j): An application for
patent no,.149056(149/Bom/77) was made by Pratap Shanker Rao Borade of
SPADMA Plastic and Engineering Industry Aurangabad Maharashtra on April
25,1977 for a method and apparatus for tagging an animal ear. The complete
specification was accepted by the Patent Office and notification was made in
Gazette of India,. Part III, Section-2 dated 29.08.1981. At the time of sealing
the method claims relating to tagging of ear were objected by the Parent
Office on the ground that the method of tagging is not an invention under
section 2(i)(j) and accordingly the amendments in the title and claims and
specification were required and therefore the applicant was informed to make
such corrections under section 78 (2) &(3) of the Act. It was argued by the
applicant that the Controller has no power to delete the claims at the time of
sealing of patent particularly Head office. If at all Controller has power to
amend the claims, this power should be exercise by the Controller at the
appropriate office. The Controller held that under the provision of section 78
(2) and (3) the Controller has powers to amend the specification by providing
an opportunity of being heard. Further the method of tagging of ear of the
animal was not held an invention under section 2(1)(j) of the patents Act
1970,not being a manner of manufacture. In the present context also such
methods can not be considered as an invention due to lack of industrial
application of the invention .
246
10.5 Date of patent (S. 45)
1. The date of patent is the date of filing of the application. The date will
be entered in the register of Patents. The purpose of "date of patent" is
for calculating the duration of a patent and reckoning the time for
payment of renewal fee.
2. In spite of date of filing being the date of patent, a suit or proceeding
cannot be commenced or prosecuted against infringement committed
before the date of publication.
The patent right is not an obsolete right. It is fettered right and it is subjected
the following constraints: any machine, apparatus or other article in respect of
which the patent is granted or any article made in respect of which the patent is
granted may be used, by any person, for the purpose merely of experiment or
research including the imparting of instructions to the students.
247
8.710.9 Patent rights not infringed when used on foreign vessels, etc., temporarily
or accidentally in India (S. 49)
The use of the invention on board a vessel or aircraft registered in a foreign
country or a land vehicle owned by a person ordinarily resident in such
country, which comes to India (including the territorial waters thereof)
temporarily or accidentally, will not infringe the rights of the Patentee.
However this will not apply to vessels, aircraft or land vehicles owned by
persons ordinarily resident in a foreign country the laws of which do not
confer corresponding rights with respect to the use of inventions in vessels,
aircraft or land vehicles owned by person, ordinarily resident in India while
in the ports or within the territorial water of that foreign country or otherwise
within the jurisdiction of its courts. As there is no commercial intention,
there is no violation of patent right.
248
in writing so to do by any of the other persons so registered, the Controller
may, upon application made to him in the prescribed manner by any such
other person, give directions empowering any person to execute that
instrument or to do that thing in the name and on behalf of the person in
default [S.51(2)].
(iii) An application for directions under sub-section (1) of section 51 shall be
made in Form 11, in duplicate, and shall be accompanied by a statement
setting out the facts upon which the applicant relies. A copy of the
application and of the statement should be sent by the Controller to every
other person registered as grantee or proprietor of the patent[S.51(1)], or to
the person in default [S.51(2)], as the case may be , and the applicant shall
supply sufficient number of copies for that purpose.
iii) Before giving any directions in pursuance of an application under this section,
the Controller shall give an opportunity to be heard to the other person or
persons registered as grantee or proprietor of the patent or to the person in
default. No direction will be given under this section so as to affect the
mutual rights or obligations of trustees or of the legal representatives of a
deceased person or of their rights or obligations as such, or which is
inconsistent with the terms of any agreement between person registered as
grantee or proprietor of the Patent.
iv) Also the Controller has the power to grant a patent to the true and first inventor
with the same date and number of a patent which has been revoked on the
ground that it had been obtained by the patentee in fraud S.52

CHAPTER XI
PATENT OF ADDITION
Relevant Sections and Rules:
Section 54 :
Patents of addition.—
(3) A patent shall not be granted as a patent of addition unless the date of
filing of the application was the same as or later than the date of filing of
the application in respect of the main invention.
(4) A patent of addition shall not be granted before grant of the patent for the
main invention.
Section 55:
Term of patents of addition.
(1) A patent of addition shall be granted for a term equal to that of the patent
for the main invention, or so much thereof as has not expired, and shall
remain in force during that term or until the previous cesser of the
patent for the main invention and no longer:
Provided that if the patent for the main invention is revoked under this Act,
the court, or, as the case may be, the Controller, on request made to him
by the patentee in the prescribed manner, may order that the patent of
addition shall become an independent patent for the remainder of the
250
term for the patent for the main invention and thereupon the patent shall
continue in force as an independent patent accordingly.
Section 56 :
Validity of patents of addition.—
(1) The grant of a patent of addition shall not be refused, and a patent
granted as a patent of addition shall not be revoked or invalidated, on
the ground only that the invention claimed in the complete specification
does not involve any inventive step having regard to any publication or use
of—
(a) the main invention described in the complete specification relating
thereto; or
(b) any improvement in or modification of the main invention described
in the complete specification of a patent of addition to the patent for
the main invention or of an application for such a patent of addition,
and the validity of a patent of addition shall not be questioned on the
ground that the invention ought to have been the subject of an
independent patent.
(2) For the removal of doubts it is hereby declared that in determining the
novelty of the invention claimed in the complete specification filed in
pursuance of an application for a patent of addition regard shall be had
also to the complete specification in which the main invention is
described.
ii) However a Patent of Addition will not be granted unless the date filing of
Application was the same or later than the date of filing of the complete
specification in respect of the main invention (S. 54(1),S. 54 (2) & S. 54(3)).
251
iii) It should be noted that a patent of addition will not be granted before granting
of the patent for the main invention.
iv) In an application for a patent of addition, the determination as to whether the
invention proposed is or is not an improvement or modification of the
applicant’s previous invention, has to be done by the proper comparison
between the novel contributions which each specification has made to the art
and not between the sum of the characteristics claimed in the respective
main invention and proposed patent of addition. In other words mere
presence of a number of elements common to both inventions, is not
sufficient to make one invention an improvement of or addition to the other
iv) The validity of a patent of addition will not be questioned on the ground that
invention ought to have been the subject of an independent patent and on the
ground that the invention claimed in the complete specification does not
involve any inventive step having regard to the publication and use of the
main invention (Section 56)
v) For determining the novelty of the invention claimed in the complete
specification filed in pursuance of an application for patent of addition,
regard should be had to the complete specification in which the main
invention is described. Thus the complete specification of the main
invention could be cited for novelty as an anticipatory publication.
vi) The Complete Specification of application for the patent of addition shall
include specific reference to the number of main patent or the application
number of main patent, as the case may be, and a definite statement that the
invention comprises an improvement in, or a modification of the invention
claimed in the specification of the main patent, granted or applied for.
vii) When improvement is patentable:
252
No renewal fee is payable in respect of a patent of addition so long as the main
patent remain in force. However if patent of addition becomes an independent
patent, the same fee shall be payable upon the same dates as if the patent has been
originally granted as an independent patent.
