`
`INTRODUCTION
`
`U.S. Patent No. 5,856,336 (“the ʼ336 Patent”) claims the following
`
`compound (“claimed compound”), and a method of using the compound to treat
`
`disorders including hyperplipidemia (Ex. 1001, at 32:20-40):
`
`
`
`The claimed compound is limited to a single salt form, which is the “½”
`
`calcium salt in which the divalent calcium ion is bonded to two of the active
`
`moieties shown in the formula. Claim 1 of the ‘336 patent, and method-of-use
`
`claim 2 which depends from it, are invalid as obvious under 35 U.S.C. § 103
`
`because the compound and its use are nothing more than obvious variants of prior
`
`art compounds, directed to precisely the same use, disclosed in two references,
`
`Picard (Ex. 1009) and Kesseler (Ex. 1010). The specific prior art compounds
`
`disclosed in these references differ in minor respects from the claimed compound,
`
`which is attained by a single change in structure from either prior art reference. In
`
`Picard, which identifies an isopropyl substituent as having superior activity, the
`
`isopropyl substituent is changed to cyclopropyl, which is a structural isomer that is
`
`specifically named by Picard as a preferred lower alkyl group. Ex. 1009, at 4:25-
`
`
`
`1
`
`
`
`
`
`30. In Kesseler, which directly compares the superior activity of a cyclopropyl
`
`compound to its isopropyl analog, the fused-ring quinoline structure of the claimed
`
`compound is opened, to the corresponding 6-membered nitrogen containing ring
`
`and phenyl ring present in quinoline. Ex. 1010. Each of the references, alone and
`
`in combination, discloses superior activity of specific compounds that have propyl
`
`group substituents, and Kesseler points specifically to the superior activity of
`
`cyclopropyl versus isopropyl groups. Both references disclose lead compounds that
`
`are reasoned choices for further development, based on specific activity data.
`
`A unique circumstance in the present case is that the grandparent application
`
`of the ʼ336 patent was involved in two interferences, one of which involved the
`
`same Picard patent at issue here (Ex. 1009). Interf. Nos. 102,648 and 102,975, Ex.
`
`1005 and 1006, respectively. Patent Owner (Fujikawa) lost both interferences,
`
`because a third party (Wattanasin) was found to be the first inventor, and all of
`
`Fujikawa's claims were canceled. This decision was affirmed by the Federal
`
`Circuit. Fujikawa v. Wattanasin, 93 F.3d 1559 (Fed. Cir. 1996).
`
`Patent Owner's arguments and admissions concerning Picard in the
`
`interferences are highly relevant to the present IPR. Patent Owner requested the
`
`interference with Picard, by asserting that Fujikawa’s claims defined the same
`
`patentable invention as Picard. Ex. 1005, pp. 130-32. With respect to its own
`
`claims reciting both isopropyl- and cyclopropyl-substituted analogs, Patent Owner
`
`
`
`2
`
`
`
`
`
`urged that there was “clear overlap” between Picard’s claims and all of Patent
`
`Owner’s claims, and unequivocally stated:
`
`Moreover, there is absolutely no evidence of record that the
`
`varying species embraced by both claims are patentably distinct from
`
`the unsubstituted [Picard] compound discussed above. (Id. at 132).
`
`After being informed that an interference would be declared in the near
`
`future in accordance with this request (id. at 419), Patent Owner canceled the claim
`
`corresponding to ʼ336 patent claim 1 (Claim 10), to keep it out of the interference.
`
`Id. at 422. Although Patent Owner stated that this compound exhibits “unobvious
`
`and distinguishing properties” with respect to the other claims proposed for the
`
`interference, it submitted no evidence and provided no hint as to what these
`
`“distinguishing properties” might be. Id. at 423 By canceling Claim 10 to avoid
`
`the interference, Patent Owner disclaimed the subject matter that would become
`
`claim 1 of the ‘336 Patent. See the discussion in the Petition below.
`
`Picard voluntarily dropped out of the interference, leaving Patent Owner and
`
`Wattanasin as parties. Ex. 1005, p. 27. Patent Owner then sought to reintroduce
`
`Claim 10 into the interference, but only as a separate count, which required a
`
`showing that Wattansin provided written description for the claimed cyclopropyl
`
`substituent. Id. at 35. Patent Owner repeatedly argued that the disclosure of an
`
`isopropyl compound disclosed by Wattanasin would directly lead a person skilled
`
`
`
`3
`
`
`
`
`
`in the art to select cyclopropyl as a substituent, and thus attain the subject matter
`
`that is now claimed in the ’336 Patent:
`
`[T]he Wattanasin application repeatedly exemplifies isopropyl.
`
`Indeed, isopropyl is mentioned by name as an alternate substituent at
`
`the 2-position. Having been taught that isopropyl is an acceptable
`
`substituent and within the scope of Wattanasin's invention, those of
`
`skill in the art would readily arrive at the selection of cyclopropyl,
`
`out of the disclosure of cycloalkyl of 3-7 carbon atoms, as the next
`
`logical, and analogous compound, isomerically related to
`
`exemplified species.… It is well established that isomeric species
`
`are expected to behave in similar fashion, in the absence of evidence
`
`to the contrary. (Id. at 226).
`
`These statements are unquestionably correct, as shown below. Patent Owner
`
`cannot now reverse course, and is bound by its admissions concerning the
`
`substitution of cyclopropyl for isopropyl isomers, as the next logical step for
`
`modification of an isopropyl compound. It is precisely the same next logical step
`

`
`
`
`7
`
`
`
`
`
`ʼ336 Patent should be held unpatentable under 35 U.S.C. § 103(a) is provided in

`
`curriculum vitae is attached to his declaration.
`
`III. THE ʼ336 PATENT
`
`The ʼ336 Patent issued on January 5, 1999, from Application Ser. No.
`
`07/883,398, filed May 15, 1992 (Ex. 1002); which was a divisional of Ser. No.
`
`07/631,092, filed December 19, 1990 (Ex. 1003); which was a continuation of Ser.
`
`No. 07/233,752, filed August 19, 1988 (Ex. 1004).
`
`A.
`
`Field of the ʼ336 Patent
`
`The ʼ336 Patent ʼ336 is directed to mevalonolactones having a quinoline
`
`ring structures as well as their pharmaceutical uses as anti-hyperlipidemic,
`
`hypolipoproteinemic and anti-atherosclerotic agents. Ex. 1001, at 1:5-10 (i.e.,
`
`column 1, lines 5-10; hereinafter, the notation X:Y denotes column:line).
`
`
`
`8
`
`
`
`
`
`B. Claims 1 and 2 of the ʼ336 Patent
`
`Claims 1 and 2 of the ʼ336 Patent are:
`
`1. A compound of the formula,
`
`
`
`Z= —CH(OH)—CH2—CH(OH)—CH2—COO.½Ca.
`
`2. A method for reducing hyperlipidemia, hyperlipoproteinemia or
`
`atherosclerosis, which comprises administering an effective amount of the
`
`compound of formula A as defined in claim 1.
`
`Ex. 1001, at 32:20-40; Ex. 1012, ¶ 13.
`
`C. The Broadest Reasonable Construction of Claim Terms
`
`Pursuant to 37 C.F.R. § 42.104(b)(3) and 37 C.F.R. § 42.100(b), Petitioner
`
`states that the broadest reasonable interpretation of claim 1 includes all isomeric
`
`forms of the compound: “these compounds may have at least one or two
`
`asymmetric carbon atoms and may have at least two to four optical isomers. The
`
`compounds of the formula I include all of these optical isomers and all of the
`
`mixtures thereof.” See Ex. 1001, at 2:66-3:2. A person of ordinary skill in the art
`
`
`
`9
`
`
`
`
`
`(POSA) would have understood that the compound of Claim 1 of the ʼ336 Patent
`
`includes four optical isomers and mixtures thereof. Ex. 1012 at ¶ 14.
`
`For purposes of this Petition, a POSA would have held an advanced degree,
`
`such as an M.S. or a doctorate in one of the fields of medicinal or synthetic
`
`chemistry, pharmacology, with 3 to 5 years of experience working in the field of
`
`drug discovery who was familiar with mevalonolactones, including natural, semi-
`
`synthetic and fully synthetic derivatives of compactin and mevinoline and related
`
`compounds, and their pharmaceutical uses as anti-hyperlipidemic,
`
`hypolipoproteinemic and anti-atherosclerotic agents. Ex. 1012 at ¶ 15.
`
`IV. THE EFFECTIVE FILING DATE OF CLAIMS 1 AND 2 OF THE ʼ336 PATENT IS, AT
`THE EARLIEST, AUGUST 3, 1988
`
`The ʼ336 Patent claims benefit of Japanese Patent Applications JP 63-
`
`193606 (filed August 3, 1988), JP 63-15585 (filed January 26, 1988), and JP 62-
`
`207224 (filed August 20, 1987) (references to the Japanese applications herein are
`
`to the certified translations submitted by Patent Owner during prosecution of the
`
`‘752 grandparent application). Ex. 1015 (JP ʼ224), Ex. 1014 (JP ʼ585), and Ex.
`
`1013 (JP ʼ606). However, neither JP ʼ585 nor JP ʼ224 provides written description
`
`for a ½ calcium salt, as specifically required by claims 1 and 2 of the ʼ336 Patent.
`
`The earliest effective filing date for the ʼ336 Patent is no earlier than the filing date
`
`of JP ‘606. Petitioner submits that these translations constitute admissions by
`
`Patent Owner regarding the disclosure of the Japanese priority documents.
`
`
`
`10
`
`
`
`
`
`A.
`
`Single species claims require full written description support in
`order to be entitled to benefit of priority
`
`“[A] description that merely renders the invention obvious does not satisfy
`
`the [written description] requirement” of 35 U.S.C. § 112. Ariad Pharm., Inc. v.
`
`Eli Lilly & Co., 598 F.3d 1336, 1352 (Fed. Cir. 2010) (en banc) (quoting
`
`Lockwood v. Am. Airlines, 107 F.3d 1565, 1571–72 (Fed. Cir. 1997)). This is
`
`emphasized in those cases where an applicant has described a broad genus in its
`
`specification, yet has claimed only a single compound. In those cases, “[t]he
`
`question [of written description support is]…whether the [] application ‘discloses
`
`the [variants], specifically, as something appellants actually invented,’” not
`
`whether it would have been obvious to have arrived at the single compound given
`
`the disclosure of the broader genus. Novozymes A/S v. DuPont Nutrition
`
`Biosciences APS, 723 F.3d 1336, 1350 (Fed. Cir. 2013), quoting In re Ruschig, 379
`
`F.2d 990, 995 (CCPA 1967).
`
`Merely disclosing a broad genus does not provide written description
`
`support for an individually claimed species. Ruschig, 379 F.2d at 994 (“Surely,
`
`given time, a chemist could name (especially with the aid of a computer) all of the
`
`half million compounds within the scope of the broadest claim, which claim is
`
`supported by the broad disclosure. This does not constitute support for each
`
`compound individually when separately claimed.”), cited by the PTAB with
`
`
`
`11
`
`
`
`
`
`approval in Motionpoint Corp., Petitioner, CBM2014-00066, 2014 WL 3704044,
`
`at *14 (July 23, 2014).
`
`“[T]he written description requirement prohibits a patentee from ‘leaving it
`
`to the ... industry to complete an unfinished invention.’” Novozymes, 723 F.3d at
`
`1350, citing Ariad, 598 F.3d at 1353. A patentee cannot merely disclose a broad
`
`chemical genus and then successfully claim individual compounds within that
`
`genus without a disclosure sufficient to show that they possessed the individual
`
`compounds. See, e.g., Novozymes, 723 F.3
