`
`INTRODUCTION
`
`Patent Owner Cipla Ltd. (“Patent Owner”) submits this Preliminary
`
`Response to GlaxoSmithKline Consumer Healthcare Holdings (US), LLC’s
`
`(“Petitioner”) Petition seeking inter partes review of U.S. Patent No. 8,168,620
`
`(“the ’620 patent”). Petitioner’s request should be denied because it fails both on
`
`threshold issues and the merits.
`
`At the outset, the Petition fails to particularly cite to the prior art such that
`
`the Patent Trial and Appeal Board (“Board”) and Patent Owner can determine the
`
`art upon which the Petition relies. While the Petition purports to identify prior art
`
`that when combined render the claims obvious, it does little more than portray a
`
`collage of teachings across numerous references. The Petition compounds this
`
`error by attempting to incorporate dozens of additional references cited only in
`
`expert declarations and nowhere described in the Petition.
`
`The Petition also suffers from another significant threshold shortcoming—it
`
`fails to address, much less overcome, the fact that the U.S. Patent and Trademark
`
`Office (“Office”) has already considered and rejected the arguments and art set
`
`forth in the Petition. The Board’s precedent demands that where a petitioner relies
`
`on substantially the same prior art and arguments considered during prosecution,
`
`that petitioner must establish error in the Examiner’s analysis. Petitioner made no
`
`effort to make this showing, simply parroting previously rejected arguments. As set
`
`1
`
`
`
`
`
`forth in Section III, infra, the prior art and arguments relied upon in the Petition’s
`
`Grounds were considered, “of record” and had been “previously evaluated, or
`
`disclose[d] information redundant to information of record.” Ex. 1008, 37. Cramer
`
`was considered extensively during prosecution, forming the basis of multiple
`
`rejections. And Petitioner’s additional art—Segal and PDR 1999—were either
`
`expressly considered and rejected, or cumulative of information considered and
`
`rejected during prosecution. Petitioner points to nothing new to distinguish the
`
`arguments and art examined—and overcome—during prosecution. For this reason
`
`alone, the Petition should not be instituted pursuant to 35 U.S.C. § 325(d).
`
`Setting aside the Petition’s defects, Petitioner’s obviousness assertion is
`
`rooted in a fundamentally flawed principle: that a combination of known elements
`
`is obvious even though the prior art provided no impetus to create—and in fact
`
`taught away from—that combination. The ’620 patent’s claims cover Dymista®, a
`
`novel nasal spray formulated by combining
`
`two active
`
`ingredients:
`
`the
`
`antihistamine, azelastine, and the corticosteroid, fluticasone. Dymista® was a
`
`breakthrough: it was the first fixed-dose combination nasal spray to treat allergic
`
`rhinitis (“AR”). Prior to Dymista®, and despite myriad available AR treatments, no
`
`one had successfully combined an intranasal antihistamine with an intranasal
`
`corticosteroid in a fixed-dose formulation.
`
`2
`
`
`
`
`
`There was a good reason for this. Indeed, the prior art discouraged such
`
`combinations because a fixed-dose formulation presented patients and physicians
`
`several treatment difficulties. Namely, a fixed-dose formulation prevented: 1) dose
`
`adjustments, 2) use of only one of the two medications, and 3) use of different
`
`medications. Moreover, the two medications had incompatible dosing regimens.
`
`The prior art provided no motivation to make such a combination. To the contrary,
`
`the prior art taught skilled artisans that a combined steroid-antihistamine product
`
`would offer no advantage over a steroid alone. And with no guidance in the prior
`
`art, the inventors created a formulation that not only overcame those challenges,
`
`but also invented a formulation that combined a medication delivered as a
`
`suspension with a different medication delivered as a solution. Petitioner fails to
`
`address at all why—in the face of these obstacles—a skilled artisan would be
`
`motivated to do what the inventors did. Notably, FDA recognized that the
`
`development of Dymista® was particularly complex and one that raised issues that
`
`had “not been previously encountered” in the development of nasal sprays with
`
`just one active ingredient. Ex. 2008, 4.
`
`Petitioner nonetheless asserts the ’620 patent is purportedly obvious because
`
`the inventors merely combined two known therapies. But, an “invention is not
`
`obvious just because all of the elements that comprise the invention were known in
`
`the prior art.” Broadcom Corp. v. Emulex Corp., 732 F.3d 1325, 1335 (Fed. Cir.
`
`3
`
`
`
`
`
`2013) (internal quotations and citation omitted). Rather, “a finding of obviousness
`
`at the time of invention requires a plausible rational[e] as to why the prior art
`
`references would have worked together.” Id. (internal quotations and citation
`
`omitted). This
`
`requirement
`
`is absent here—Petitioner’s overly-simplistic
`
`obviousness theory fails to provide any motivation to first select these two specific
`
`monotherapies, out of all the myriad possibilities, and then combine them. There
`
`was no suggestion in the prior art as to why one might want to bring fluticasone
`
`and azelastine together into a single formulation. Quite the opposite, the prior art
`
`provided many reasons not to make such a combination. It was only the inventors’
`
`ingenuity that brought Dymista to the market, where some 20 years later, it
`
`remains the only fixed-dose combination nasal spray approved by FDA for the
`
`treatment of AR.
`
`The nonobviousness of the ’620 patent is bolstered by objective evidence,
`
`including the extensive record demonstrating commercial success (ignored by
`
`Petitioner), unexpected results, and the satisfaction of a long-felt need. This
`
`evidence was relied on by the Examiner in the original prosecution and was
`
`addressed in the prior Argentum IPR. Petitioner’s failure to address the known
`
`record evidence is, alone, another basis sufficient to deny institution here.
`
`The Board should decline to institute this proceeding.
`

`
`
`
`
`
`II. THE PETITION FAILS TO MEET ITS THRESHOLD SHOWING
`BECAUSE IT FAILS TO CITE PRIOR ART IN SUPPORT OF
`UNPATENTABILITY
`
`At the outset, the Petition makes two substantial errors for which the Board
`
`should deny institution. First, the Petition does not cite any prior art with
`
`specificity but rather improperly canvases the prior art in support of its arguments.
`
`Second, the Petition fails to explain in the Petition why the prior art renders the
`
`patent unpatentable and instead resorts to circular citations to multiple, lengthy
`
`expert declarations. For either, or both, of these reasons, the Board should decline
`
`to institute.
`
`A.
`
`The Board Should Deny the Petition under 35 U.S.C. § 314(a)
`Because It Lacks the Required Specificity.
`
`The Petition should be denied because Petitioner does not adequately put
`
`Patent Owner on notice of the precise grounds for alleged unpatentability.
`
`Petitioner posits two primary grounds under which the challenged claims are
`
`allegedly obvious—each purportedly resting on
`
`the combination of
`
`two
`
`references.1 The Petition, however, creates a confounding record with a discussion
`
`of a multitude of additional references and does not identify precisely which claim
`
`elements are allegedly present in which references.
`
`
`1 As discussed below, Petitioner challenges one claim of the ’620 patent with a
`third reference in Ground 2. See Section II.A.
`
`5
`
`
`
`
`
`To merit institution, the statute requires that “the petition identif[y], in
`
`writing and with particularity, each claim challenged, the grounds on which the
`
`challenge to each claim is based, and the evidence that supports the grounds for
`
`challenge to each claim....” 35 U.S.C. § 312(a)(3) (emphasis added). Moreover,
`
`“[t]he petition must specify where each element of the claim is found in the prior
`
`art patents or printed publications relied upon.” 37 C.F.R. § 42.104(b)(4). Here, the
`
`Petition does not adequately put Patent Owner on notice of the precise grounds for
`
`alleged unpatentability.
`
`In Grounds 1 and 3, Petitioner challenges the patentability of the ’620
`
`patent’s claims with each ground purportedly resting on a combination of two
`
`references: PDR 1999 in view of Segal and Cramer in view of PDR 1999. Ground
`
`2 applies only to dependent claim 48 and adds Hettche (Ex. 1013) as an additional
`
`reference. Ground 2 relies on, and incorporates, the arguments set forth in Ground
`
`1 and therefore presents the same defects as Ground 1. See Pet. 28-29.
`
`The Petition, however, creates a confounding record with a discussion of a
`
`multitude of additional references and does not identify precisely which claim
`
`elements are allegedly present in which references. For example, in Ground 1, the
`
`Petition identifies at least 7 additional references that appear to form the basis of
`
`the Ground. See Pet. 6-8 (citing Drouin, Brooks, Dykewicz, Berger, Cauwenberge,
`
`Spector, and Bousquet as supporting Ground 1). More references are then
`
`6
`
`
`
`
`
`discussed in the Petition’s discussion of the dependent claims. See, e.g., Pet. 17-28.
`
`The Petition does not particularize the teaching from the art in the Ground, but
`
`instead cites numerous citations to other prior art references (often in string cite
`
`form) absent explanation. Likewise, Petitioner does not include any claim charts
`
`that map the cited references to the language of the claims. Neither the Board nor
`
`Patent Owner should be expected to fill in the blanks to uncover Petitioner’s
`
`arguments. See Teoxane S.A. v. Allergan, PLC, IPR2017-02002, 2018 WL
`
`1247024, at *8 (PTAB Mar. 9, 2018) (citing DeSilva v. DiLeonardi, 181 F.3d 865,
`
`866–67 (Fed. Cir. 1999) (“A brief must make all arguments accessible to the
`
`judges, rather than ask them to play archeologist with the record.”)).
`
`The Board should reject Petitioner’s invitation to play archeologist and
`
`should instead follow the path of Zetec, Inc. v. Westinghouse Electric Co.,
`
`IPR2014-00384, 2014 WL 3704254 (PTAB July 23, 2014), and exercise its
`
`discretion under 35 U.S.C. § 314(a) and 37 C.F.R. § 42.108(b) to deny institution.
`
`Zetec, 2014 WL 3704254, at *7-10 (denying institution because “attempting to
`
`evaluate fully the…underdeveloped assertions in the Petition to determine whether
`
`Petitioner has shown that it would be likely to prevail in any unpatentability
`
`challenge would place a significant burden on the Board and contravene the
`
`efficient administration of the Office”); see also Schumer v. Lab. Comput. Sys.,
`
`Inc., 308 F.3d 1304, 1316 (Fed. Cir. 2002) (“It is not our task . . . to attempt to
`
`7
`
`
`
`
`
`interpret confusing or general testimony to determine whether a case of invalidity
`
`has been made out.”). As in Zetec, the Board should decline to expend its resources
`
`scouring the numerous references cited by Petitioner to determine if the identified
`
`combinations (or some other, unidentified combination) demonstrate a reasonable
`
`likelihood that Petitioner would prevail. Zetec, 2014 WL 3704254, at *9
`
`(“Appellant’s Brief is at best an invitation to the court to scour the record, research
`
`any legal theory that comes to mind, and serve generally as an advocate for the
`
`appellant. We decline the invitation.” (citations omitted)).
`
`B.
`
`The Board Should Not Consider Evidence Included in Expert
`Declarations But Not Cited in the Petition.
`
`In deciding whether to institute this review, the Board should not consider
`
`arguments included in the expert declarations but not discussed in the Petition. 37
`
`C.F.R. § 42.6(a)(3) prohibits arguments being incorporated by reference from one
`
`document to another in an IPR proceeding. This includes information in expert
`
`declarations. See Tempur Sealy Int’l Inc. v. Select Comfort Corp., IPR 2014-01419,
`
`Paper 7 at 7-8 (PTAB Feb. 17, 2015); Cisco Sys., Inc., v. C-Cation Techs., LLC,
`
`IPR2014-00454, 2014 WL 4352301, at *5-6 (PTAB Aug. 29, 2014) (expanded
`
`panel decision explaining that arguments not made in the Petition will not be
`
`considered); Fidelity Nat’l Info. Servs., Inc., v. DataTreasury Corp., IPR2014-
`
`00489, 2014 WL 4059220, at *5 (PTAB Aug. 13, 2014) (“Under our rules, the
`
`petition must contain a ‘full statement of the reasons for the relief requested,
`
`8
`
`
`
`
`
`including a detailed explanation of the significance of the evidence....’ We,
`
`therefore, decline to consider information presented in a supporting declaration,
`
`but not discussed sufficiently in a petition.” (citation omitted)); see also Trial
`
`Practice Guide Update (August 2018) at 4.
`
`Just as Petitioner glosses over the Grounds, Petitioner also incorporates by
`
`reference vast swaths of expert declarations with little, and often no, discussion in
`
`the Petition. Indeed, in this Petition, setting aside Exhibits 1001-1008 which
`
`contain the four challenged patents and excerpts from their file histories, the
`
`Petition’s exhibit list identifies 52 exhibits, only 19 of which are cited in the
`
`Petition. The remaining 33 exhibits2 are omitted from discussion in the Petition.
`
`None of these omitted exhibits should be considered by the Board.
`
`Petitioner’s attempts to impermissibly incorporate by reference is well
`
`illustrated in the Petition’s limited discussion of certain secondary indicia of
`
`nonobviousness. See Pet. 59-62. For example, the Petition gives short shrift to
`
`overcoming the established unexpected results of the ’620 patent—devoting just
`
`over two pages to the issue. Yet, the Petition incorporates 58 paragraphs spanning
`
`22 pages from the Schleimer Declaration. Pet. 59 (incorporating paragraphs 602-
`
`660 from the Schleimer Declaration). Worse, in those 58 paragraphs at least six
`
`
`2 The non-referenced exhibits are Exhibit Nos. 1014-1015, 1017-1018, 1020, 1025-
`1031, 1034, 1036-1037, and 1039-1056.
`
`9
`
`
`
`
`
`references are discussed in detail and none of them are cited in the Petition. The
`
`Petition suffers the same problems with respect to the criticisms of the declaration
`
`by one of the named inventors, Malhotra (“Malhotra Declaration”), submitted
`
`during prosecution that evidenced the inoperability of Example III in Cramer. See
`
`Pet. 60-61.
`
`Petitioner’s attempts to discount the claimed invention’s satisfaction of a
`
`long-felt and unmet need provide an even more egregious example. There, the
`
`Petition includes just four lines, yet cites to 18 paragraphs in the Schleimer
`
`declaration spanning five pages with reference to several additional exhibits, which
`
`are again not cited in the Petition. See Pet. 61. The line and a half of argume
