Identification of Challenge
A.
1.
The 208 Patent was filed on September 17, 2002 and claims benefit of
provisional applications Nos. 60/324,165 and 60/402,317, for which the earliest
filing date is September 21, 2001. (Ex. 1001 Front Cover.)
The 208 Patent is titled Lactam Containing Compounds and Derivatives
[Type text]
[Type text]
[Type text]
[Type text]
[Type text]
The claims at issue here can be summarized as a typical funnel that begins
with an enormous number of alternatives in the only independent claim (claim
1) of 103 claims, composed of Markush group alternatives for different subunits of the overall molecular structure that is claimed. As with any claimfunnel, the scope of the independent claim is further limited through a chain of
dependent claims. In this case, the total number of claimed variations or
alternatives is decreased until a single molecular formula is claimed, inter alia,
in claim 13. The reduction in claim scope is accomplished not through the
[Type text]
[Type text]
[Type text]
addition of new claim elements, but through the successive reduction in the
number of alternative formulations possible under each dependent claim. Id. at
26.
Claim 13 depends, ultimately from claim 1. Due to the chain of claim
dependency (i.e., claim 13 depends from claim 8 and claim 8 depends from
claim 1) the patent owner cannot deny that the single compound of claim 13 is
claimed in each of the earlier claims in that chain since a dependent claim must
contain all of the elements of any claim from which it depends. Id. at 27. MPEP
608.01(i)(c) (Claims in dependent form shall be construed to include all the
limitations of the claim incorporated by reference into the dependent claim).
The claims at issue here do nothing more than progressively restrict the
large number of alternative compounds claimed in claim 1 until they are reduced
to a few (claims 2-8) or a single molecule (e.g. claim 13). Ex. 1008 at 28.
Further, if claim 13 is determined to have been taught in the prior art, no
antecedent claims can be found nonobvious. Calloway Golf Company v.
Acushnet Company, 576 F.3d 1331, 1344 (Fed. Cir. 2009) (A broader
independent claim cannot be nonobvious where a dependent claim stemming
from that independent claim is invalid for obviousness).
What follows is a general description of the claims that are at issue in this
IPR petition:
[Type
text]
[Type text]
[Type text]
Claim 1, the only independent claim in the 208 Patent, recites a generic
claim for a compound of the formula:
wherein P4 is further defined as -G1-G and M4 is A-B1 . Ex. 1001 237: 3-10 and
When the P and M rings defined in the amendment are fused via the
Structure 1
Where P4 is replaced by G1-G as defined in claim 1 of the 208 Patent. M4
was further defined in the Certificate of Correction for claim 1 to be the A-B unit
which results in the structure of the ring system being:
[Type
text]
[Type text]
[Type text]
Cert. of Cor. pg 2 correcting line 34. The components of this generic formula are
set forth as a massive listing of nested chemical moieties in the form of multiple
Markush groups that take up over five columns of the patent consisting of
inestimable combinations. The claim concludes with or a pharmaceutically
acceptable salt thereof. Ex. 1001 at 237:1-242:23 and Cert. of Cor. pg 1-2
correcting multiple entries in all of columns 237-242; Ex. 1008 at 30.
Claim 2 depends from claim 1 and recites a subset of the enormous range
of compounds in claim 1 by listing alternatives for a subunit (labeled G) of the
P4 moiety and a subunit (labeled A) of the M4 moiety of the formula provided
above. Id. at 242:24-245:29 and Cert. of Cor. pg 2-3 correcting columns 243
and 244. Even this narrowing would results in, still, millions of potential
combinations. Ex. 1008 at 31.
Claim 3 depends from claim 2 and defines a list of 168 alternatives for
moiety G in the form of structural formulae. In the addition it provides that G1
is absent or selected from a list of generic formulae, each with multiple
variations and further limits moiety A. Ex. 1001 at 245:30-254:41 and Cert.
Structure 2
Structure 2 appears in the 208 Patent at 134:60 (where R1a = H). Ex. 1008 at 45
[Type
text]
[Type text]
[Type text]
of Corr. pg 3-5 correcting columns 246, 248, 249, 251-254; Ex. 1008 at 32.
Claim 4 depends from claim 3 and narrates 96 alternative structural
variations for the G moiety, a subset of the 168 in claim 3. Claim 4 also
includes the alternative that G1 is absent or chosen form another list of
alternatives that themselves include variations chosen from one or more of 12
groups of additional variables. Id. at 254:42-259:67 and Cert. of Corr. pg 5-6
correcting columns 255, 256, 258 and 259; Ex. 1008 at 33.
Claim 5 depends from claim 4, and continuing with the theme of claims 3
and 4, recites 58 alternatives for the G moiety as structural formulae (a subset
of the 96 listed in claim 4) and number of additional alternatives including the
A and B moieties. Id. at 260:1 -263:44 and Cert. of Corr. pg 6-7 correcting
columns 261-263; Ex. 1008 at 34.
Claim 6 depends from claim 5, and, again recites a vast subset of
structural alternatives in which G1 is absent with 27 alternatives for moiety G
and two alternatives for A-B. Id. at 263:45-265:28 and Cert. of Corr. pg 7
correcting col 265 lines 20-25; Ex. 1008 at 35.
Claim 7 depends from claim 6 and defines a single alternative for the
moiety labeled -A-B. The -A-B structural unit is included in all of the
claims that are at issue in this IPR, but is never shown in any of the structural
diagrams or demonstrated in the specifications with particularity. It is merely
[Type
text]
[Type text]
[Type text]
defined in the claims. Id. at 265:29-39 and Cert. of Cor. pg 7 correcting line 35
by deleting the second structure; Ex. 1008 at 36.
Claim 8 depends from claim 1, and claims a compound according to
claim 1 wherein the compound is selected from a group of 65 specific
compounds or a pharmaceutically acceptable salt form thereof admitted to
being covered by the generic formula of claim 1. Ex. 1001 at 265:39-268:41 and
see also Cert. of Corr pg 7 correcting col 655 line 66 from pyrazole- to
pyrazolo- as well as other numerous corrections; Ex. 1008 at 37.
Claim 13 depends from claim 8, and recites a single compound, 1-(4methoxyphenyl)-7-oxo-6-4[4-(2-oxo-1-piperidinyl)phenyl-4,5,6,7-tetrahydro1Hpyrazolo-[3,4-c]pyridine-3-carboxamide or a pharmaceutically acceptable
salt form thereof, which is the ninth compound of the 65 compounds listed in
claim 8. Id. at 269:1-6 and see also Cert. of Corr. page 10 correcting col 269
line 4 from pyrazole- to pyrazolo- as well as other corrections;
Ex. 1008 at 38.
Claims 9-12, 20-27, and 34-61 all depend from one of the abovedescribed claims and add nothing of patentable distinction, but rather simply
recite, for example, a specific condition for which the compounds claimed in the
claims above may be administered Ex. 1001 passim; Ex. 1008 at 39.

The application that led to the 208 Patent was filed on September 17,
2002 and contained 30 claims. A restriction requirement was issued on
September 29, 2003. In issuing the restriction requirement the examiner stated
that all 30 claims were generic and that an election of a single species for
examination was required. In response the applicant elected 2(1-(4methoxyphenyl)-3-[(methylamino)methyl]-6-[-4-(2-oxo-1-piperdinyl)phenyl]1,4,5,6-tetrahydro-7H-pyrazolo[3,4-c]pyridine-7-one.
The first, and only, substantive office action on the merits was issued on
October 23, 2003. In the action claims 1-21 were rejected and claims 22-30
were withdrawn for being drawn to non-elected subject matter. The rejected
claims were characterized as constituting an improper Markush group. The
variables P and M that made up the two core rings of the generic formula
were originally submitted as follows:
P4-P-M-M4
The examiner then requested changes in the core of the compound that
determines classification for the purposes of examination. Ex. 1002 at 4.
A response was filed on November 19, 2003 that cancelled claims 9-15
and 2-30 that left claims 1-8 and 16-19 pending. Claims 31-121 were then
added. Claim 1 was amended such that the generic formula above was replaced
with the formula illustrated here
[Type

[Type text]
11
[Type text]
Perhaps the most significant event in the prosecution of the 208 was the 13
page Certificate of Correction that was filed by the patent owner. The corrections
resulted in numerous changes to the claims Ex. 1001 Cert. of Corr. pg 1-13. In
addition to the above-mentioned definition of M4 as A-B,(Cert. of Corr. pg 2)
the other changes specifically relevant to this IPR are correction of the spelling of
[Type
text]
[Type text]
12
[Type text]
the name of the compound in claim 13, and the correction of that same compound
name in the list of those in claim 8 by replacing pyrazole with pyrazolo. Ex
1001, Cert. of Corr. at pg 7 and 10; Ex. 1008 at 46. It should be noted that while
this request for an IPR is limited to validity challenges for anticipation and
obviousness, the Certificate of Correction for the 208 Patent raises serious
questions about the validity of the 208 claims under 35 U.S.C. 112. The
corrections go well beyond fixing typographical errors and the like, as is
appropriate in a Certificate of Correction. MPEP 1481 (the Director mayissue
a certificate of correction, if the correction does not involve such changes in the
patent as would constitute new matter or would require examination) These
changes did indeed add new matter and substantive language to the claims that was
never considered by any examiner. Further, many of the corrections go to
renaming previously examined compounds. For example, the Certificate reads,
P4 is G1-G; should read M4 is A-B; P4 is G1-G; Ex1001 Cert. of Corr. at 2.
As set forth below, the A-B units added as a correction do appear in the Patent
Owners own prior art relied upon in this request. The corrections improperly
added new, unexamined, chemical structures into the patent without the benefit of
any prior art analysis. Id.

The references relied upon to establish the invalidity of the 208 Patent are a

[Type text]
[Type text]

[Type text]
version of that PCT application filed in the U.S. without claiming priority to the
PCT. Both the PCT application and the U.S. Patent claim priority to the same two
U.S. Provisional Applications, US 60/127,633 and US 60/113,628. The published
application is prior art under 35 USC 102(b) and the U.S. Patent is prior art under
35 USC 102(e)(2).
1. PCT Publication No. WO 00/39131 (Ex. 1003)
International Publication No. WO 00/39131 (here after Fevig I) entitled
Nitrogen Containing Heterocycles of Factor Xa Inhibitors was published on
July 6, 2000. It does not designate the United States and was filed before
November 29, 2000. Therefore, Fevig I is 102(b) prior art as of its publication
date. MPEP 2136.03 II(B). The publication date of the Fevig I application, July
6, 2000, is more than one year before September 21, 2001, the earliest priority
date of the 208 Patent. Ex 1001 Front Cover. Fevig I is over 300 pages long
and, like the 208 Patent, discloses an enormous number of compounds claimed to
be Factor Xa inhibitors. Ex. 1003 passim; Ex. 1008 at 55.
Fevig I is mentioned in the 208 Patent, and was submitted on an IDS
disclosing prior art document references during the prosecution of the application
leading to the 208 Patent but Fevig I was not substantively considered by the
Examiner during prosecution of the 208 Patent. Despite the fact that Fevig I was
disclosed to the examiner in an expansive dump of prior art during prosecution of
[Type text]
[Type text]
16
[Type text]
the 208 Patent, it is undeniable that the compound disclosed in claim 13 of the
208 Patent is also explicitly disclosed in Fevig I. The examiner, who was
undoubtedly under time constraints, would not have the time to appreciate the fact
that the claims of the 208 are covered by the disclosure of Fevig I given the
enormously complicated Markush structure of the both Fevig I and the 208
Patent.
Apparently acknowledging the substantial overlap between the disclosure
of Fevig I and the 208 Patent, the Patent Owner, in describing the scope of Fevig
I in the Background of the Invention section of the 208 Patent states
[c]ompounds specifically described in WO 00/39131 are not considered to be
part of the present invention. Ex. 1001 at 2:62 Regardless of what the Patent
Owner believes to be part of the 208 Patents inventions, the Patent Owner
cannot disclaim what its own prior art publication actually discloses. There is
nothing inventive about claiming compounds identical to those found in the prior
art.
2. U. S. Patent 6,413,980 (Ex. 1004)
U.S. Patent 6,413,980 (Ex. 1004, here after Fevig II) has the identical
specification as Fevig I. Ex. 1008 at 57. It was filed on December 22, 1999,
which was five days after the filing of the Fevig I application and almost two years
before September 21, 2001, the earliest potential priority date for the 208 Patent.
[Type text]
[Type text]
17
[Type text]
Pre-AIA 35 U.S.C. 102(e)(2) states in pertinent part that a reference is prior art to
an invention if:
the invention was described in a patent granted on an application for
patent by another filed in the United States before the invention by the
applicant for patent.
The inventive entity of the Fevig II is different from that of the 208,
therefore it qualifies as by another under the Patent Act. MPEP 2136.04(I) (If
there is any difference in the inventive entity, the reference is by another).
Fevig II and the 208 Patent have four inventors in common, Han, Lam, Pinto, and
Pruitt. Fevig II also lists as inventors Fevig, Cacciola, Clark, Pruitt, and Rossi,
who are not inventors on the 208 Patent. Conversely, the 208 Patent lists Orwat,
Li, Qiao and Koch as inventors who are not inventors on Fevig II. Ex 1001 and
1004 front pages. Thus, the 980 meets the requirements of prior art under 35 USC
102(e) by virtue of its filing date by another. It is worth noting that since there is
a time bar under 35 USC 102(b) by virtue of the Fevig I publication, Fevig II
cannot be overcome as prior art by establishing that it is the work of one of the
inventors of the 208. MPEP 2136.05(II) (stating that an inventor may overcome a
102(e) rejection based on his or her own work, unless there is a time bar under
pre-AIA 35 USC 102(b)).
Like Fevig I, Fevig II was disclosed to the examiner during prosecution, but
[Type

The level of skill in the art is apparent from the cited art. Further, a person
having ordinary skill in the art would have either a Pharm. D. or a Ph.D. in organic
chemistry, pharmacy, pharmacology, or a related discipline; or a Bachelors or
[Type text]
[Type text]
19
[Type text]
Masters degree in organic chemistry or a related field with at least four years of
experience relating to compounds that are or may be Factor Xa inhibitors. A person
of ordinary skill in the art would have collaborated with others having expertise in,
for example, methods of treating diseases and administering medicines. Ex. 1008 at
61.
VI.
the claimed invention, either explicitly or inherently. Verdegaal Bros. v. Union Oil
Co. of California, 814 F.2d 628, 631 (Fed. Cir. 1987). As set forth below, the
specific compound claimed in claim 13 of the 208 Patent, the same compound
claimed as an alternative in claim 8, and the same compound from a larger number
of alternatives in claims 1-7 was disclosed in Fevig I more than one year before the
earliest priority date of the 208 Patent, and therefore those claims of the 208 are
anticipated under 35 U.S.C. 102(b).
Claim 1 of the 208 Patent is extraordinarily long. It covers almost 6
columns of the patent. Additionally, significant changes were made to the claim in
a 13-page Certificate of Correction. Ex 1001. Large portions of the claim are
extended lists of molecular subunits written in Markush form, e.g. moieties
[Type text]
[Type text]
20
[Type text]
selected from the list. There are 34 such lists of subunits from which to select
from in claim 1 alone. Ex. 1008 at 63.
Rather than first attacking the tremendous breadth of claim 1 to demonstrate
that it and the other claims at issue in this request for IPR are anticipated
specifically by Fevig I, Petitioner will instead begin by showing that the single
compound of claim 13 in the 208 Patent is specifically disclosed in Fevig I. Once
this has been established Petitioner will proceed to show that that same compound
is specifically claimed in each of the other challenged claims. Demonstration of the
presence of this single compound in any of claims 1-8 is sufficient to invalidate
each of those claims since each is a Markush-style claim and anticipation of a single
member anticipates the entire group. Application of Ruff, 256 F.2d 590, 593
(CCPA 1958); Atlas Powder Co. v. Ireco, Inc., 190 F.3d 1342, 1346, 51
U.S.P.Q.2d (BNA) 1943 (Fed. Cir. 1999) (In chemical compounds, a single prior
art species within the patents claimed genus reads on the generic claim and
anticipates.).
Additionally, as will be discussed below in more detail, the case law
supports the presented arguments for anticipation and obviousness based on a
broad prior art genus anticipating specific compounds or rendering later generic
claims obvious. App. of Susi, 440 F.2d 442; 169 U.S.P.Q. 423 (CCPA, 1971)

Structure 4
Ex. 1008 at 66.
This exact formula of Structure 4 appears in Fevig I as the first structure on
the left at the top of page 4 (there are no line numbers on that page). Ex 1003 at
pg. 4; Ex. 1008 at 67. Petitioner will take each variable in Structure 4, above, in
turn and show that the appropriately disclosed alternative for each variable of the
structure results in anticipating the apixaban structure from Fevig I.
Variable s
Fevig I defines s as at each occurrence, is selected from 0, 1, 2 or 3.
Ex. 1003 at 15:9 . For the apixaban structure, s equals zero, such that G is
attached directly to the nitrogen atom with no intervening spacer groups. Ex. 1008
at 68.

pg. 10:15. In the case of apixaban, ring D is absent Ex. 1008 at 70. When ring D
is absent, ring E is selected from phenyl, pyridyl, pyrimidyl, pyrazinyl, and ring
E is substituted with R and R. Ex. 1003 at 10:17-18. For the apixaban
structure, E is the phenyl alternative. Ex. 1008 at 70. Further to the apixaban
structure, R is H (taught specifically at Ex. 1003 pg. 10:24) and R is methoxy
(as specifically taught within C1-3 alkoxy alternatives as the C1 alkoxy at Ex.
1003 pg10:20). Ex. 1008 at 70. These selections result in a G component that
is a methoxy-phenyl group. Id. When this G ring is substituted into Structure 4
(with s = 0), the structure looks like this:

Id.
Variable Z
The Z moiety is defined as N or CR1a ". Ex. 1003 at p 10:29. For the
apixaban structure, the CR1a alternative is chosen with R1a defined as, among
other alternatives, -(CH2)r-R1. Ex 1003 at pg. 11:3. Ex. 1008 at 71. Continuing
the nested definition, r is defined as equaling 0, 1, 2 or 3. Ex. 1003 at pg. 15:7.

[Type text]
For the apixaban structure the alternative r = 0 is appropriate. Ex. 1008 at 71.
This selection means that Z = CR1. Id. A number of alternatives for R1 are
provided. Ex 1003 at 11:6-12. For the apixaban structure R1 is the C(O)NR2R2a
alternative. Ex 1003 at 11:9; Ex. 1008 at 71. Continuing the solution of the
apixaban puzzle, Fevig I provides appropriate alternatives from the list provided.
Ex. 1003 at 11:17-25. To demonstrate the apixaban structure both R2 and R2a are
hydrogen (H) atoms, which are specifically set out in the list of alternatives. Ex.
1003 at 11:17 and 11:22; Ex. 1008 at 71. Combining these subunits gives Z= CC(O)NH2. Id. Substituting this Z into Structure 5 results in:

A comparison of Structure 6 with apixaban (Structure 3) shows that they are

Variable A
A is specifically defined as a C3-10 carbocyclic residue substituted with 02 R4. Ex 1003 at pg. 12:20. So a C6 carbocycle, e.g. a phenyl ring, with zero R4

one nitrogen atom will satisfy the ring alternative. Ex. 1008 at 73. R4a is defined in
Fevig I by a long list of alternatives, one of which is a carbonyl oxygen =O. Ex
1003 at 13:24. Attaching this alternative for B to Structure 7 results in this

disclosure and there is no question that apixaban is one of the specifically claimed
alternatives in claim 1 of the 208 Patent. Finally, the complexity of Fevig I is
entirely due to the conscious decisions of the Patent Owner, and thus there is no
equitable justification for allowing it to be saved by unnecessary clutter of its own
creation.
As with all of the challenged claims in this IPR, the claimed compounds of
claim 1 are represented by Structure 4:

elements. Ex. 1008 at 82. Rather, Petitioner feels having shown with specificity
that the Fevig I reference specifically discloses and claims apixaban, petitioner
need only show that apixaban is claimed in each of the other challenged claims in
order to establish that they too are anticipated. Upsher-Smith Labs., Inc. v.
Pamlab, L.L.C., 412 F.3d 1319, 1322 (Fed. Cir. 2005)(a product which would
literally infringe if later in time anticipates if earlier). The claiming of apixaban
in claims 1-7 of the 208 Patent is set forth below.
As a preliminary matter, this demonstration is unnecessary by virtue of the
chain of dependent claims created by the patent owner. Claim 13 ultimately
depends from claim 1 and thus patent owner admits that claim 1 covers apixaban.
Claim 8 also depends from claim 1, and thus there is further admission that
apixaban is covered by claim 1. Finally claims 2-7 all depend, or ultimately
depend, from claim 1 and since they are narrowed, not by the addition of new
elements, but by reducing the number of alternative compounds claimed, each of
them also covers apixaban and is thus anticipated by Fevig I. Ex. 1008 at 83.
Claim 1 defines moiety G of Structure 1 as one of these two ring systems,
G is a group of Formula IIa or IIb:

The fused pyrazole-lactam ring system is defined in the corrected claim 1. Ex.
1001, Cert. of Corr. at pg 2; Ex. 1008 at 86-87.
Accordingly, Petitioner need now only demonstrate the presence of A and
B in claim 1 to complete the structure of apixaban. Ex. 1008 at 89.
The corrected claim 1 defines M4 of Structure 1 as A-B. Ex 1001 Cert. of
Corr. at pg. 2 (M4 is A-B). A is defined as a C3-C10 carbocycle substituted with
0-2 R4. Ex 1001 238 a:20-21. One of the alternatives for R4 is zero. For
apixaban, when R4 is zero and the carbocycle is a C6 phenyl ring, the resulting
structure is:

lines 33 and 34). A saturated six-membered lactam ring attached to A through
the lactam-nitrogen atom meets these limitations for B. Apixaban has zero R4a
substituents. Ex. 1008 at 91. A saturated six-membered lactam ring attached to
A through the lactam-nitrogen atom meets these limitations for B. Id.
Plugging in this disclosed structural limitation for B results in the complete

I reference. Id.
7. Anticipation of Claim 5 by Fevig I.
Claim 5 depends from claim 4 and again starts by again defining the G
unit as methoxy-phenyl, among others. Ex. 1001 at 260:5-11. The claim also
defines the A unit as phenyl among other choices. Id. at 262:31. Finally
claim 5 defines the B unit as the moiety found in the apixaban structure
substituted with R4a. Id. at 262 37-43 (first structure on the left; also Cert. of
Corr. pg 6-7 correcting column 262). R4a in the apixaban structure is H as
claimed in claim 5. Id. at 263:24 first structure; Ex.1008 at 100.
8. Anticipation of claim 6 by Fevig I.
Claim 6 depends from claim 5 and begins by claiming the generic structure:

[Type text]
36
[Type text]
These are the A and B rings that Petitioner has previously identified as being
disclosed by Fevig I and claimed in all of the challenged claims in this IPR. Ex.
1008 at 78. The chain of dependency for claim 6 goes all the way back to claim 1
and thus includes all the limitations of all of the underlying claims. Claim 1
defined M4 as A-B. Id. 237:34-35 and Cert. of Corr. at page 2. So replacement of
P4 with methoxy-phenyl and M4 with A-B produces a compound that is identical
with that of Structure 3, apixaban, except that it contains the variable R1a. Ex.
1008 at 103. To complete the apixaban structure R1a needs to be an amide moiety.
Claim 5 defines R1a as an amide group, among others and as claim 6 depends from
claim 5 and claim 6 is silent as to the R1a , the R1a is carried into claim 6. Ex 1001
at 262:61; Ex. 1008 at 103. Accordingly, apixaban is claimed in claim 6.
9. Anticipation of Claim 7 by Fevig I.
Claim 7 depends from claim 6 and further defines the A-B unit. The
claim provides A-B as

Fevig I (and Fevig II) anticipate, almost verbatim, claims 9-12, 20-27, and
34-61. For ease of reference and to conserve space, a claim chart illustrating the
anticipation of claims 9-12, 20-27, and 34-61 by Fevig I is presented later in
Section B(4), below.
B. Ground 2: U.S. Patent 6,413,980 to Fevig et. al (Fevig II) (Ex.
1004) anticipates claims 1-13, 20-27, and 34-61 of U.S. 6,967,208 under
35 U.S.C. 102(e).
As set forth in Section V(D)(2) above, Fevig II qualifies as prior art under
35 U.S.C. 102(e)(2). Also, as explained above, the specification of Fevig II is
identical to Fevig I. Accordingly, Petitioner need not repeat the reasoning set forth
for why Fevig I anticipates the challenged claims of the 208 Patent, but rather
only need provide the specific cites to Fevig II for the identical disclosure cited for
Fevig I.
Before pointing out the relevant portions of Fevig II that establish
anticipation of the challenged claims of the 208, it should be noted that a broad
genus of the type asserted in this petition against the 208 was also asserted against
Fevig II during its prosecution.
The examiner rejected claims 1, 8, 10 and 11 of the application for Fevig II
over Duplantier, WO 95/01980. Ex. 1005 p. 369. Specifically, the examiner

This exact structure appears in Fevig II. Ex. 1004 at 3:6-15 first structure on
the left of column 3. Substituting the variables with specifically disclosed options
produces the structure of apixaban. Ex. 1008 at 110.
Variable s
As was the case with the identical disclosure in Fevig I, the s group in
Fevig II is defined at each occurrence to be selected from 0, 1 and 2. Ex 1004
at 10:21. For the target compound apixaban, s is zero. Ex. 1008 at 111.
Variable G
Variable G is defined as the same two bicyclic ring systems as also found in
Fevig 1 as well as the 208 Patent, namely:
D
I
[Type

[Type

[Type text]
Ex 1004 at 7:24-35; Ex. 1008 at 112. The description goes on to state that
alternatively ring D is absent Id. at 7:50. As with Fevig I, when ring D is absent,
ring E is selected from phenyl, pyridyl, pyrimidyl, pyrazinyl, and ring E is
substituted with R and R. (Ex 1004 col 7:51-53). For the apixaban structure, E
is the phenyl alternative, R is methoxy as specifically taught within C1-3 alkoxy
alternatives as a C1 alkoxy (Ex. 1004 col 7:54) and R is H (Ex. 1007 col 7:58).
When this G ring is substituted into Structure 4 (with s = 0), the resulting
structure is
B

N

Structure 5
Variable Z
As in Fevig I, Z is defined as being selected from N or CR1a . (Ex.
1004 col 7:64. R1a is defined, among others, as (CH2)-R1. Id. at 8:1. In the
continuing nesting of variables, r is defined as 0, 1, 2 or 3. Id. at 10:19. For
apixaban, r = zero. R1 is further defined as C(O)NR2R2a, among others. Id. at 8:89. R2 and R2a are each defined in the alternative as H. Id. at 8:17 and 8:25. With
this selection of alternatives the structure disclosed becomes:

Similarly, B is defined is defined as a 5-10 membered heterocyclic
system containing 1-4 heteroatoms selected from the group consisting of N, O, and
S substituted with 0-2R4a. Id. at 8:62-67. B as a C6 heterocycle made with five
carbons and with an N hetero atom will satisfy the ring alternative. R4a is defined
as a carbonyl oxygen =O within the parameters of the disclosure of Fevig II Id. at
9:33. Replacing A and B of the structure above with these disclosed

Thus, exactly as was the case with Fevig I, Fevig II anticipates the
challenged claims of the 208 Patent by disclosing, among other compounds,
apixaban, which is explicitly disclosed by name in claims 13 and 8 and generically
in claims 1-7.
2. Anticipation of Claim 8 Fevig II.
As set forth in the discussion of Fevig I, Claim 8 is directed to a compound
according to claim 1, wherein the compound is selected from the group. Wherein
the group is a list of 65 individual compounds taking up approximately 3
columns of the 208 Patent. Reproducing the listing of compounds here would
serve little purpose. The significant observation regarding claim 8 is that the
single compound claimed in claim 13, 1-(4-methoxyphenyl)-7-oxo-6-4[4-(2-oxo1-piperidinyl)phenyl-4,5,6,7-tetrahydro-1Hpyrazolo-[3,4-c]pyridine-3carboxamide, is among the compounds listed. Ex. 1001 at 265:65. Ex. 1008 at
118.
The anticipation analysis of Claim 8 is identical to that of claim 13 with
[Type
text]
[Type text]
43
[Type text]
respect to this particular compound, vida supra. As set forth above, the case law
is clear that when one member of a Markush group is anticipated, the entire
group is anticipated. Application of Ruff, 256 F.2d 590, 593 (CCPA 1958); Atlas
Powder Co. v. Ireco, Inc., 190 F.3d 1342, 1346, 51 U.S.P.Q.2d (BNA) 1943
(Fed. Cir. 1999) (In chemical compounds, a single prior art species within the
patents claimed genus reads on the generic claim and anticipates.).
There is no question that claim 8 is a Markush claim. MPEP 2173.05(H)
(Markush claim means any claim that recites a list of alternatively useable
species regardless of format). The analysis of claim 13 plainly demonstrates
that the claim is anticipated by the disclosure of Fevig II. Claim 8 merely places
the compound of claim 13 into a listing of a specific species of compounds
presented as a choice of 65 compounds. Ex. 1008 at 120. As cited above, the case
law is clear that the entire group in claim 8 is anticipated by the disclosure of one
of the compounds presented in the alternative, in this case, apixaban in Fevig II.
3. Anticipation of Claim 1-7 Fevig II.
As was done for Fevig I, Petitioner has established that claims 13 and 8 are
anticipated by Fevig II. The analysis for the remainder of the challenged claims
of the 208 is accomplished by showing that the scope of each of claims 1-7
covers apixaban, and thus they too are anticipated by the disclosure of apixaban in
Fevig II. Since the disclosures of Fevig I and II are identical, Petitioner presents

208 Patent with their location in both Fevig I and II. The same correlation holds
true for the rest of the Challenged Claims, and they are not presented here since
the complete overlap of the disclosure if Fevig I and Fevig II is undeniably
demonstrated by this table. Ex. 1008 at 121.

Grounds 3 and 4: Fevig I and Fevig II, each in its own right,
renders the challenged claims of the 208 Patent obvious under
35 U.S.C. 103(a).
[Type

[Type text]
While Petitioner feels that the detailed explanation offered for Grounds 1
and 2 clearly establishes that the challenged claims of the 208 Patent are
anticipated under 102(b) for Fevig I and under 102(e)(2) for Fevig II, if this Board
does not reach the same conclusion, then it should at least conclude that, based on
the above-presented evidence, that both the Fevig I and Fevig II references render
the challenged claims obvious under 103(a) on Grounds 3 and 4.
Both prior art references and the patent for which review is sought belong to
the same assignee, Bristol-Myers Squib. And all three documents disclose the
compound Petitioner has chosen to use to establish the invalidity of the 208
Patent, namely apixaban.
It is anticipated that the Patent Owner will argue against this Petition by
asserting that the genera of the Fevig prior art is too vast and undifferentiated to
steer one of ordinary skill to pick one particular compound, thus there is no
anticipation or obviousness with respect to the challenged claims. Patent Owner
may also argue that the disclosures that it created are so broad and so convoluted
that one of ordinary skill would not be motivated to ferret out any specific
compound.
If the Board sees fit to allow Patent Owners to create absurdly complicated
claim schemes and then to argue that the very schemes and disclosures that they
created, and had the opportunity to simplify, are immune from use as prior art, it is

Circuit cited to Susi for support of these positions and characterized the holding in
Susi as an obviousness rejection affirmed where the disclosure of the prior art
was huge, but it undeniably include[d] at least some of the compounds recited in
[applicants] generic claims and it is of a class of chemicals used for the same
purpose as [applicants] additives. Merck at 807.
That is precisely the situation in this case. Fevig I and II disclose a vast
number of compounds that undeniably includes apixaban, a compound admitted
by Patent Owner to be covered by generic claim 1 of the 208 Patent, and from
which all of the challenged claims ultimately depend. The compounds disclosed
in the Fevig references are Factor Xa inhibitors, which are identical to the
nature of the compounds claimed in the 208 Patent. Ex. 1008 at 123-26.
In Merck, Plaintiff had argued that the prior art did not suggest that the
compounds within the claimed genus were preferred embodiments, and therefore
did not render the later claimed compounds obvious. Merck at 807. In response
the Federal Circuit said that with respect to an analysis under section 103, all
disclosures of the prior art, including unpreferred embodiments, must be
considered. Merck at 708.
It has been demonstrated with respect Grounds 1 and 2 with regard to
anticipation by Fevig I and II that the broad genus of claim 1 of the 208 Patent
(and all of the remaining challenged claims that depend from it) reads on the prior

VII. Conclusion
As set forth in detail above, apixaban, the specific compound claimed in
claim 13 of the 208 Patent is claimed in each of the challenged claims. There is no
argument that all of the moieties that the patent owner chose to break apixaban into
in order to claim them as separate variables are not present in each challenged claim
(other than 13 which only claims apixaban). The only potential roadblock to
reaching this conclusion comes from having to piece together apixaban via a
labyrinth of nested components with variations on variations.
