`
`INTRODUCTION
`
`Ayla Pharma LLC (“Petitioner”) petitions for Inter Partes Review (“IPR”),
`
`and seeks cancellation of Claims 1–13 (“challenged claims”) of U.S. Patent
`
`No. 9,533,053 (“the ’053 patent”) (EX1002).
`
`II. OVERVIEW
`
`The patent family to which the ’053 patent belongs has a troubled past
`
`before the PTAB. The parent patent, U.S. Patent No. 8,791,154 (EX1001), has
`
`already been subject to an IPR challenge by Argentum. Argentum Pharm. LLC v.
`
`Alcon Research, Ltd., IPR2016-00544, Paper 1 (P.T.A.B. Feb. 2, 2016) (EX1021).
`
`In response to that Petition, the PTAB instituted review of U.S. Patent No.
`
`8,791,154 (parent patent) (“the ’154 patent”) on every challenged claim on every
`
`ground. Id., Paper 8 (EX1015). Shortly thereafter, Apotex filed another petition
`
`seeking joinder with Petitioner Argentum. See Apotex, Inc. v. Alcon Research Ltd.,
`
`IPR2016-01640, Paper 2, (P.T.A.B. Aug. 18, 2016) (EX1016); id., Paper 3
`
`(EX1022). The PTAB granted joinder. Id., Paper 8 (EX1023). Rather than
`
`allowing Argentum or Apotex’s IPR challenges to proceed as to the parent patent,
`
`Alcon settled with both of them. Id., Paper 9 (EX1024). Similarly, Cipla filed two
`
`petitions seeking review of the ’154 patent and the ’053 patent, but settled shortly
`
`thereafter. Cipla Ltd. v. Alcon Research, Ltd., IPR2018-01021, Paper 9 (P.T.A.B.
`
`Sept. 17, 2018), and IPR2018-01020, Paper 11 (P.T.A.B. Sept. 17, 2018).
`
`142718351v2
`
`
`
`Petition for Inter Partes Review
` of U.S. Patent No. 9,533,053
`
`Not surprisingly, the claims of the ’053 patent are similar to the claims of the
`
`’154 (parent) patent. Generally, the claims of the ’053 patent cover a composition
`
`of a well-known drug—olopatadine—for
`
`the
`
`treatment of ocular allergy
`
`symptoms, which olopatadine was known to treat. Physicians’ Desk Reference,
`
`62nd ed., 532-533 (2008) (“PDR”) (EX1011) (disclosing PATADAY™ and
`
`PATANOL®);1 EX1002, 1:30-35. The other claim limitations of the ’053 patent
`
`recite common classes of excipients used in ophthalmic formulations including
`
`those containing olopatadine. Nothing new is claimed. EX1014, ¶ 70.
`
`Tellingly, the claims of the ’053 patent are not only similar to those of the
`
`’154 patent, but also are broader in scope. For example, although independent
`
`Claim 1 of the ‘053 patent includes claim limitations that are identical to or with
`
`overlapping scope to those of Claim 1 of the ‘154 patent, it excludes the limitation
`
`of benzalkonium chloride (which is in Claim 2 of the ‘053 patent). EX1001,
`
`26:35; EX1002, 27:56-57. Thus, the inescapable conclusion is that Claim 1 of the
`
`’053 patent, among others with a claim scope similar or broader to the ’154 patent
`
`1 PDR was published 2008 and is prior art under 35 U.S.C. § 102(b). PDR was not
`
`disclosed to or discussed by the Examiner during prosecution of the ’053 patent.

`
`
`
`Petition for Inter Partes Review
` of U.S. Patent No. 9,533,053
`
`claims, is unpatentable for at least the same reasons adopted by the Board in its
`
`institution decision for the ’154 patent. See, e.g., EX1015, 9-11, 19-22.
`
`For these reasons, and the additional reasons set forth in the more detailed
`
`description below, the Board should institute Inter Partes review and cancel
`
`Claims 1-13 of the ’053 patent.
`
`III.
`
`STANDING (37 C.F.R. § 42.104(a); PROCEDURAL STATEMENTS)
`
`Petitioner certifies that: (1) the ’053 patent is available for IPR; and
`
`(2) Petitioner is not barred or estopped from requesting IPR of any claim of the

`
`with 37 C.F.R. § 42.106(a). Filed herewith are a Power of Attorney and an Exhibit
`
`List pursuant to § 42.10(b) and § 42.63(e). The required fee is paid through an

`
`STATEMENT OF THE PRECISE RELIEF REQUESTED AND THE
`REASONS THEREFOR (37 C.F.R. § 42.22(a))
`
`Petitioner requests IPR and cancellation of Claims 1–13 of the ’053 patent.
`
`Petitioner’s full statement of the reasons for the relief requested is set forth in
`
`detail below.
`
`VI. THE ’053 PATENT
`
`The ’053 patent has two independent claims (Claim 1 and 8). EX1002.
`
`Claim 1 recites an aqueous ophthalmic solution for treatment of ocular allergic
`
`conjunctivitis comprising: at least 0.67 w/v% olopatadine dissolved in the
`
`solution; PEG having a molecular weight of 200 to 800; polyvinylpyrrolidone; a
`
`142718351v2
`

`
`
`
`Petition for Inter Partes Review
` of U.S. Patent No. 9,533,053
`
`cyclodextrin selected
`
`from
`
`the group consisting of SAE-β-cyclodextrin,
`
`hydroxypropyl-β-cyclodextrin and hydroxypropyl-γ-cyclodextrin; and water.
`
`EX1002, 27:46-55. Claim 8 is similar to Claim 1 but includes benzalkonium
`
`chloride and hydroxypropyl methylcellulose (“HPMC”). The associated dependent
`
`claims, generally speaking, recite additional amounts of excipients, or incorporate
`
`the results according to the “FDA accepted CAC model.” EX1014, ¶ 39.
`
`A.
`
`Claim Construction
`
`As noted above, the ’154 patent was previously subject to an IPR. Argentum
`
`Pharm. LLC, IPR2016-00544. The ’053 patent is a continuation of the application
`
`that led to the ’154 patent. In IPR2016-00544, the PTAB gave preliminary
`
`constructions for the ’154 patent:
`
`Term
`Preamble
`“w/v %”
`
`EX1015, 7.
`
`Construction
`
`Non-limiting
`The mass of the component in grams per 100 milliliters of
`solution multiplied by 100 (EX1014, ¶ 42)
`
`The PTAB declined to construe the preambles of Claims 1, 4, 8, and 21, as
`
`well
`
`as
`
`the
`
`phrase
`
`“solution
`
`comprising…at
`
`least
`
`0.67 w/v %
`
`olopatadine…dissolved
`
`in
`
`the solution,” at
`
`the
`
`time of
`
`institution of
`
`IPR2016-00544, finding no construction was necessary in light of the claim term
`
`“comprising.” Id., 6.
`
`142718351v2
`
`6
`
`
`
`Petition for Inter Partes Review
` of U.S. Patent No. 9,533,053
`
`For completeness, the District of Delaware provided the following
`
`constructions with respect to the ’154 patent:
`
`Construction
`The preamble is limiting.
`
`An aqueous ophthalmic solution for treatment of ocular
`allergic conjunctivitis that contains at least 0.67 w/v %
`[but no greater than 1.0 w/v % olopatadine] dissolved in
`the solution.
`
`Term
`aqueous
` “An
`solution
`ophthalmic
`for the treatment of
`ocular
`allergic
`conjunctivitis,
`the
`solution comprising...”
`“at least 0.67 w/v %
`olopatadine dissolved
`in the solution” and “at
`least 0.67 w/v % but
`no greater than 1.0 w/v
`%
`olopatadine
`dissolved
`in
`the
`solution”
`
`EX1017, 2.
`
`The preambles of Claims 1 and 8 of the ’053 patent (EX1002) are the same
`
`as the preambles of the ’154 patent (EX1001). Petitioner contends that the PTAB
`
`does not have to resolve any discrepancy between its preliminary construction for
`
`the ’154 patent and the district court’s construction because, as the PTAB noted, in
`
`IPR2016-00544, it is not necessary to determine the precise limiting nature of the
`
`preamble because the identified evidence in IPR2016-00544 was sufficient to show
`
`that the preambles were taught or otherwise suggested by the relied-upon art.
`
`EX1015, 6. Petitioner contends the evidence presented herein addresses these
`
`limitations.
`
`142718351v2
`
`7
`
`
`
`Petition for Inter Partes Review
` of U.S. Patent No. 9,533,053
`
`As to the district court’s construction of the ’154 patent’s recitation of “at
`
`least 0.67 w/v % olopatadine dissolved in the solution,” again the limitation
`
`appears in the ’053 patent and Petitioner submits that the plain and ordinary
`
`meaning would at least encompass the district court’s construction. In any event,
`
`Petitioner contends the evidence presented herein addresses these limitations.
`
`For all other terms, Petitioner submits that no further construction is
`
`necessary and the challenged claims should be afforded a meaning “in accordance
`
`with the ordinary and customary meaning of such claim as understood by one of
`
`ordinary skill in the art and the prosecution history pertaining to the patent.” 37
`
`C.F.R. § 42.100(b); Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005)
`
`(en banc).
`
`VII. NONE OF THE CLAIMS ARE ENTITLED TO THE PRIORITY
`DATE OF PROVISIONAL APPLICATION 61/487,789
`
`The ’053 patent claims priority to two U.S. Provisional Applications,
`
`61/487,789 (EX1009, “the ’789 Provisional”) and 61/548,957 (EX1010), filed
`
`May 19, 2011, and October 19, 2011, respectively. The Office never considered
`
`priority during prosecution of the ’053 patent, and no presumption of priority
`
`applies. PowerOasis, Inc. v. T-Mobile USA, 522 F.3d 1299, 1305 (Fed. Cir. 2008).
`
`Raising a priority issue involves “identifying, specifically, the features,
`
`claims, and ancestral applications allegedly lacking § 112, first paragraph, written
`
`142718351v2
`
`8
`
`
`
`Petition for Inter Partes Review
` of U.S. Patent No. 9,533,053
`
`description and enabling disclosure support for the claims based on the identified
`
`features.” Polaris Wireless, Inc. v. TruePosition, Inc., IPR2013-00323, Paper 9 at
`
`29 (P.T.A.B. Nov. 15, 2013); SAP America, Inc. v. Pi-Net Int’l., Inc.,
`
`IPR2014-00414, Paper 11 at 13-14 (P.T.A.B. Aug. 8, 2014). The test for
`
`sufficiency under the written description requirement of 35 U.S.C. § 112 ¶ 1 is
`
`whether the application disclosure relied on reasonably conveys to a POSA that the
`
`inventors had possession of the claimed subject matter. Ariad Pharms., Inc. v. Eli
`
`Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc).
`
`None of the claims of the ’053 patent are supported by the ’789 Provisional.
`
`The
`
`independent
`
`claims
`
`of
`
`the
`
`’053
`
`patent
`
`recite
`
`a
`
`“hydroxypropyl-γ-cyclodextrin.” EX1002. The ’789 Provisional fails to even
`
`mention any γ-cyclodextrins or derivatives of γ-cyclodextrins; instead, the ’789
`
`Provisional exclusively focuses on “includ[ing] a β-cyclodextrin derivative to aid
`
`in the solubility of the olopatadine” (EX1009, Bates page 9, lines 2-7), with all
`
`examples relying on a β-cyclodextrin derivative (id., Tables A-H). Therefore, the
`
`’789 Provisional fails to reasonably convey to the skilled artisan the inclusion of
`
`hydroxypropyl-γ-cyclodextrin in the compositions, and therefore fails to support
`
`142718351v2
`
`9
`
`
`
`Petition for Inter Partes Review
` of U.S. Patent No. 9,533,053
`
`that Patent Owner had possession of such compositions at the time of filing of the
`
`’789 Provisional. EX1014, ¶¶ 27-29.2
`
`Because Claims 1-13 of
`
`the ’053 patent find no support
`
`in
`
`the
`
`’789 Provisional and cannot benefit from the filing date of the ’789 Provisional,
`
`the ’053 patent should not be afforded the October 19, 2011 priority date of
`
`Provisional Application No. 61/548,957 (EX1010).
`
`VIII. A PERSON OF ORDINARY SKILL IN THE ART
`
`As of the relevant priority date,3 a POSA in the relevant field would have
`
`had: (i) an M.D., Pharm. D., or Ph.D. in chemistry, biochemistry, pharmaceutics,
`
`2 Unless stated otherwise, Petitioner’s expert, Dr. S. Craig Dyar (“Dr. Dyar”),
`
`agrees with the findings and conclusions of Dr. Laskar (EX1014), and adopts those
`
`findings and conclusions as if they were his own, including those pertaining to the
`
`‘053 patent. EX1042, ¶¶13-14. All citations to Dr. Lasker’s opinions in this
`
`Petition shall subsume and/or encompass a citation to Dr. Dyar’s concurring
`
`opinion at EX1042, ¶¶13-14.
`
`3 Even if the PTAB decides the correct priority date is May 19, 2011, rather than
`
`October 19, 2011, given the closeness of these two dates, the understanding of a
`
`POSA would not change, and related testimony of the POSA would not change.
`
`EX1014, ¶48.
`
`142718351v2
`
`10
`
`
`
`Petition for Inter Partes Review
` of U.S. Patent No. 9,533,053
`
`or in a related field, and at least about two years of relevant experience in the
`
`treatment of ocular diseases and developing formulations used to treat ocular
`
`diseases, including topical eye pharmaceuticals; (ii) a master’s degree in chemistry,
`
`biochemistry, pharmaceutics, or in a related field, and at least about five years of
`
`the same relevant experience; or (iii) a bachelor’s degree in pharmacy, chemistry,
`
`biochemistry, or in a related field, and have at least about 10 years of the same
`
`relevant experience.
`
`Further, a POSA would typically work as part of a multidisciplinary team
`
`and draw upon not only his or her own skills, but also take advantage of certain
`
`specialized skills of others in the team to solve a given problem should the need
`
`arise. EX1014, ¶ 30-35.
`
`IX.
`
`IDENTIFICATION OF CHALLENGE (37 C.F.R. § 42.104(b))
`
`Petitioner respectfully requests IPR of Claims 1-13 of the ’053 patent on
`
`each specific ground of unpatentability outlined below. Per 37 C.F.R. § 42.6(d),
`
`copies of the references are filed herewith. In support of the proposed grounds,
`
`this Petition includes the Declaration of Dr. Dyar (EX1042) explaining what the art
`
`would have conveyed to a POSA as of the priority date of the ’053 patent. See
`
`supra n.2.

`
`is that a reference was disclosed to the Examiner during the prosecution.” Amgen

`
`X.
`
`INVALIDITY ANALYSIS
`
`The inquiry for obviousness was established in Graham v. John Deere Co.
`
`of Kansas City, 383 U.S. 1 (1966). The Graham factors require an examination of:
`
`(1) the scope and content of the prior art; (2) differences between the prior art and
`
`142718351v2
`
`12
`
`
`
`Petition for Inter Partes Review
` of U.S. Patent No. 9,533,053
`
`the claims at issue; (3) the level of ordinary skill in the pertinent art; and
`
`(4) secondary considerations of nonobviousness.
