`Petition for Inter Partes Review of U.S. Patent No. 8,685,930 B2
`
`
`Famy Care Limited (“Famy Care” or “Petitioner”) petitions for Inter Partes
`
`Review, seeking cancellation of claims 1-36 of U.S. Patent No. 8,685,930 B2,
`
`which issued on April 1, 2014, to Acheampong et al. (“the ’930 patent”) (Exhibit
`
`(“Ex.”) 1001). PTO records identify Allergan, Inc. as the ’930 patent’s assignee
`
`(“Patent Owner”). This Petition demonstrates the reasonable likelihood that claims
`
`1-36 of the ’930 patent are unpatentable over the asserted prior art. Petitioner has
`
`filed companion petitions addressing related patents assigned to the Patent Owner.
`
`All challenged patents are continuations from the same family and terminally
`
`disclaimed over one another. The patents claim an ophthalmic emulsion for
`
`treating various ocular disorders, or conventional methods of administeration.
`
`Petitioner has concurrently filed a Power of Attorney and Exhibit List
`
`pursuant to 37 C.F.R. §§ 42.10(b) and 42.63(e), respectively. The $34,600 fee
`
`required under 37 C.F.R. § 42.15(a) was paid from Deposit Acct. No. 503626. The
`
`Office is authorized to charge underpayments and credit overpayments to Deposit

`Petition for Inter Partes Review of U.S. Patent No. 8,685,930 B2
`
`I.
`
`INTRODUCTION.
`
`The ’930 patent (EX1001) claims a 0.05% by weight cyclosporine A
`
`(“CsA”) topical ophthalmic emulsion used to treat keratoconjuntivitis sicca or dry
`
`eye syndrome (“KCS”)—which the specification labels “Composition II.”
`
`EX1001, 13:48-58. The claims also include using Composition II to increase tear
`
`production in humans with KCS (claim 25). The specification states that
`
`Composition II “provides overall efficacy in treating dry eye disease substantially
`
`equal to that of Composition I,” which is identical to Composition II except that it
`
`contains 0.1% by weight CsA. Id., 13:48-58, 13:63-67.
`
`The ’930 patent’s 0.1% CsA Composition I comparator matches Example
`
`1D of Allergan’s Ding ’979 prior art patent. EX1006, 4:31-43. But Ding ’979
`
`Example 1E was a 0.05% by weight CsA formulation with 50% less castor oil
`
`(0.0625%) than Composition II (1.25%). Id. Ding ’979 taught “pharmaceutical
`
`emulsion[s]” encompassing them all. Id., 6:35-42 (claim 8—ingredients of
`
`between “about 0.05% and about 0.40%” CsA; and “about 0.625% and about
`
`5.0%” castor oil). The Example 1 formulations used only 0.04 or 0.08 CsA/castor
`
`oil ratios—the claimed Composition II uses 0.04. EX1002 ¶¶31, 57. Ding ’979
`
`taught: preferences narrowing the scope of preferred formulations (id., 3:15-20);
`
`uses “for treatment of keratoconjunctivitis sicca (dry eye) syndrome” (id., 5:10-
`
`12); and that the Example 1A-D formulations shared in vivo similarities in “ocular
`
` 2
`
`
`
`
`
`

`

`Petition for Inter Partes Review of U.S. Patent No. 8,685,930 B2
`
`bioavailability” while showing “no difference in toxicity” as CsA and castor oil
`
`amounts varied. Id., 5:15:28. Thus, the specific CsA or castor oil amounts are not
`
`critical to operability. Id., 4:31-43, 5:10-28, 6:35-42. Allergan’s published clinical
`
`trial data (e.g., EX1007) confirmed comparable human clinical outcomes for
`
`0.05% and 0.1% CsA formulations. EX1003, ¶¶65-66.
`
`On obviousness, while prosecuting a parent application, Allergan1 admitted
`
`the claimed Composition II emulsion “is squarely within the teaching of the Ding
`
`[’979] reference” and “would have been obvious” to a person of skill in the art at
`
`the time of the invention. EX1005-0435.
`
`Allergan disavowed its admission after creating purported “unexpected
`
`results” that Composition II was “equally or more therapeutically effective” than
`
`Composition I. EX1004-0195. But Allergan’s unpublished and later-generated pK
`
`and/or population data cannot alter the expectations of ordinarily-skilled artisans;
`
`and the comparative-performance attributes were known, inherent or otherwise
`
`reasonably expected by the prior art. Long felt need or commercial success lack
`
`nexus. Allergan’s “secondary considerations” evidence thus cannot show
`
`nonobviousness. EX1003, ¶¶157-99.
`
`Consequently, as this Petition explains, the claims of the ’930 patent are
`
`anticipated and/or obvious on multiple grounds.
`
`1 Petitioner uses “Allergan” to include the individual patent applicants.

`II. MANDATORY NOTICES (37 C.F.R. § 42.8(a)(1)).
`
`The following mandatory notices as part of this Petition are provided below
`
`pursuant to 37 C.F.R. §§ 42.8(a)(1) and 42.8(b).
`
`A. Real Party-In-Interest (37 C.F.R. § 42.8(b)(1)).
`
`Petitioner Famy Care Limited is a real party in interest, as are its partners for
`
`its cyclosporine product: Lupin Atlantis Holdings S.A. and Axar Pharmaceuticals,
`
`Inc. Out of an abundance of caution, Famy Care Limited also identifies certain
`
`other entities as potential additional real parties in interest: Lupin Pharmaceuticals,
`
`Inc., Lupin Limited, and Lupin Inc.
`
`B. Related Matters (37 C.F.R. § 42.8(b)(2)).
`
`Mylan Pharmaceuticals Inc. filed an IPR petition for the ’930 patent
`
`(IPR2016-1127), as well as petitions for related Patent Nos. 8,629,111 (IPR2016-
`
`1128), 8,642,556 (IPR2016-01129), 8,633,162 (IPR2016-01130), 8,648,048
`
`(IPR2016-01131), and 9,248,191
`
`(IPR2016-01132).
`
` Allergan submitted
`
`preliminary responses, and on December 8, 2016 the Office instituted inter partes
`
`review on these patents. Mylan Pharm., Inc. v. Allergan, Inc., IPR2016-01127,
`
`Paper No. 8 (P.T.A.B. Dec. 8, 2016) (EX1031).
`
`Argentum Pharmaceuticals LLC (“Argentum”) filed an IPR petition for U.S.
`
`Patent No. 8,629,111 (IPR2016-01232). Apotex Corp. and Apotex Inc. filed an
`
`IPR petition for the ’930 patent (IPR2015-01283), as well as petitions for related

`
`(IPR2015-01286), and 8,629,111 (IPR2015-01282). These petitions were all
`
`terminated before institution decisions.
`
`Allergan asserted the ’930 patent and related patents against Petitioner Famy
`
`Care in Allergan, Inc. v. Famy Care Ltd., No. 2:16-cv-0401, in the Eastern District
`
`of Texas (EX1023). A complaint asserting the ’930 patent against Petitioner was
`
`served no earlier than April 15, 2016. Petitioner identifies the following pending
`
`actions involving the ’930 patent: Allergan, Inc. v. Teva Pharmaceuticals USA,
`
`Inc., et al., No. 2:15-cv-1455; and Allergan, Inc., v. DEVA Holding AS, No. 2:16-
`
`cv-1447, both in the Eastern District of Texas.

`
`V. OVERVIEW OF THE ’930 PATENT.
`
`A.
`
`’930 Patent Claims.
`
`Independent claim 1 is representative, requiring a topical ophthalmic
`
`emulsion for treating an eye of a human having KCS, comprising by weight:
`
`0.05% CsA; 1.25% castor oil; polysorbate 80; acrylate/C10-30 alkyl acrylate
`
`cross-polymer (“cross-polymer”); and water. Claim 1 requires the composition to
`
`be “therapeutically effective in treating” KCS. Independent claims 13 and 25
`
`recite an identical emulsion, but require respectively that it be “therapeutically
`
`effective in treating dry eye” and “therapeutically effective in increasing tear
`
`production” in eyes of humans having KCS. Claims 2-12, 14-24, and 26-36
`
`ultimately depend respectively from claims 1, 13, and 25.
`
`Claims 2-6, 9-10, 14-18, 21-22, 26-30, and 33-34 require the emulsion to
`
`comprise a tonicity or demulcent agent, specifically glycerine, and/or a buffer,
`
`specifically sodium hydroxide.
`
`Claims 12, 24, and 36 specify a range of pH values for the emulsions of
`
`claims 6, 18, or 30, respectively, which each comprise glycerine and a buffer.
`
`Claims 7-8, 19-20, and 31-32 specify known weight percentages of
`
`polysorbate 80 and a cross-polymer, respectively.

`
`
`
`

`

`
`Claims 11, 23, and 35 each require that when the emulsion is administered
`
`there be substantially no detectable CsA concentration in the blood.
`
`Applying the most detailed claim requirements above for the “topical
`
`ophthalmic emulsion” yields the ‘930 patent specification’s “Composition II.”
`
`EX1001, 13:45-59, 14:41-16:50; EX1002, ¶152.
`
`B.
`
`’930 Patent Prosecution History.
`
`U.S. Patent Application No. 13/961,828 (“the ’828 application”) was filed
`
`on August 7, 2013, and issued on April 1, 2014 as the ’930 patent. The ’828
`
`application was a continuation, via U.S. applications 11/897,177 and 10/927,857
`
`(“the ’857 application,” EX1005), which claimed benefit to U.S. provisional
`
`application 60/503,137, filed September 15, 2003.
`
`The Examiner issued obviousness, rather than anticipation, rejections. But
`
`during prosecution of
`
`the ’857 application, Allergan admitted
`
`that
`
`the
`
`specification’s Composition II—fully claimed by the ’930 patent (EX1002, ¶¶57-
`
`58)— falls “squarely within the teachings of Ding [’979]”:
`
`The applicants concede that it would have been obvious to modify
`examples 1A-1E of the Ding reference to arrive at Composition II of
`the present application. The differences are insignificant .... As the
`examiner correctly observes, one of ordinary skill in the art “would
`readily envisage” such a composition, especially in view of Example
`1B: having selected 0.05% as the concentration of cyclosporin,
`
` 8
`
`
`
`
`
`

`

`Petition for Inter Partes Review of U.S. Patent No. 8,685,930 B2
`
`Example 1B (wherein the ratio of cyclosporin to castor oil is 0.04)
`teaches that the concentration of castor oil should be 1.250% (0.05% /
`1.250% = 0.04). The applicants concede that in making this selection
`(0.05% cyclosporin and 1.250% castor oil) there would have been a
`reasonable expectation of success; the differences between Examples
`1A-1E and Composition II are too small to believe otherwise.
`
`The formulation of Composition II is squarely within the teachings
`of the Ding reference, and the Office should disregard any
`statements by the applicants suggesting otherwise [.]
`
`EX1005-0435 (emphases added).
`
`When prosecuting the ’828 application, Allergan acknowledged its prior
`
`admission, but alleged new unexpected results evidence justified patentability over
`
`Ding ’979. EX1004-0007. As Section XI below discusses, it does not.
`
`VI. PERSON OF ORDINARY SKILL IN THE ART.
`
`For the ’930 patent, the ordinarily-skilled artisan in the relevant field as of
`
`September 15, 20032 would have some combination of: (a) knowledge regarding
`
`designing and preparing products intended for ocular administration; and/or (b) the
`
`ability to understand results and findings presented or published by others in the
`
`field. EX1002, ¶65. Typically this person would have an advanced degree, such as
`
`
`2 The earliest provisional date; Petitioner reserves its priority challenge rights in
`
` 9
`
`
`
`this and other proceedings.
`
`
`
`

`
`an M.D., or a Ph.D. in organic chemistry, pharmaceutical chemistry, medicinal
`
`chemistry, pharmaceutics, physical pharmacy, or a related field, or less education
`
`but considerable professional experience in these fields. Id.
`
`The ordinarily-skilled artisan typically would work as part of a multi-
`
`disciplinary 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. EX1002, ¶66. As of September 15, 2003, the state of the art included the
`
`teachings provided by the references discussed in each of the unpatentability
`
`grounds set forth below. Additionally, a person of ordinary skill in the art would
`
`have been aware of other important information and references relating to dry eye,
`
`its causes, and useful treatments. Id.
`
`VII. STATE OF THE ART AS OF SEPTEMBER 15, 2003.
`
`Prior to September 15, 2003, the art recognized inflammation contributed to
`
`certain dry eye diseases. E.g., EX1012-0001-02; EX1002, ¶¶94-113; EX1003,
`
`¶¶60-72. Dry eye disease was defined as “a deficiency in either the aqueous or
`
`mucin components of the precorneal tear film. The most commonly encountered
`
`aqueous-deficient dry eye in the United States is keratoconjunctivitis sicca
`
`[KCS]….” EX1013-0004; EX1003, ¶60.
`
`Topical ophthalmic administration of CsA, a known anti-inflammatory
`
`agent, significantly reduced inflammation markers associated with dry eye.
`
`10
`
`
`
`

`

`Petition for Inter Partes Review of U.S. Patent No. 8,685,930 B2
`
`EX1012-0001; EX1002, ¶¶96-97; EX1003, ¶¶61, 63-67. Allergan’s experts
`
`conceded during prosecution that “[i]t was known in the art … that cyclosporin
`
`could be administered topically locally to the eye to target and treat dry eye by
`
`using cyclosporin A’s immunomodulatory properties[.]” EX1004-0201.
`
`Castor oil vehicles were used for topical ophthalmic administration of highly
`
`lipophilic drugs, like CsA, that must be formulated in a water-solubilized form.
`
`EX1006, 1:40-44, 3:7-14; EX1010, 5:57-63; EX1002, ¶¶102-13. Methods to
`
`determine optimal oil-to-drug ratios were well established in the art before
`
`September 2003. See generally EX1009; EX1002, ¶104. The art recognized that
`
`higher castor oil concentrations in a vehicle increased ocular residence time.
`
`EX1010, 2:61-65 (“relief is limited by the retention time of the administered
`
`artificial tear solution in the eye.”), 6:1-8:25, Figs. 2-6 (reporting that castor oil
`
`vehicles without CsA were effective in treating KCS), Fig. 7 (showing ocular
`
`residence times for 2.5%, 1.25%, 0.625% and 0.125% castor oil).
`
`Clinical trials established the safety and efficacy of CsA/castor oil emulsions
`
`for treatment of dry eye disease/KCS. EX1002, ¶¶96-97, 107; EX1003, ¶¶63-67.
`
`Kunert reported that topical 0.05% CsA emulsions in castor oil significantly
`
`decreased lymphocyte activation markers, concluding that this treatment “may help
`
`to reduce the pathophysiological factors contributing to the development of KCS.”
`
`EX1012-0007; EX1003, ¶63. Turner reported that topical 0.05% CsA emulsions
`
`11
`
`
`
`

`

`Petition for Inter Partes Review of U.S. Patent No. 8,685,930 B2
`
`in castor oil decreased inflammation markers in dry eye patients. EX1014-0001;
`
`EX1003, ¶63. Stevenson concluded from a Phase 2 dose-ranging trial (0.05%-
`
`0.4% CsA emulsions) that 0.05% and 0.10% CsA emulsions were “the most
`
`appropriate” because “no additional benefits were observed with the higher
`
`concentrations.” EX1015-0001; EX1003, ¶64.
`
`Clinical trials conducted before September 2003 showed castor oil provided
`
`a “large therapeutic effect” to patients suffering from KCS. E.g., EX1014-0005;
`
`EX1015-0007; EX1002, ¶¶102-07; EX1003, ¶¶63-64. This “therapeutic effect of
`
`the [castor] oil-in-water vehicle” was “expected, as topical application of certain
`
`lipid mixtures can accelerate epidermal barrier recovery after defined barrier
`
`insults in mice.” EX1014-0005.
`
`Thus, the art well knew 0.05% CsA/castor oil formulations were effective to
`
`increase tear production and relieve dry eye disease/KCS. EX1002, ¶¶102-13;
`
`EX1003, ¶¶71-79.
`
`VIII. PRIOR ART.
`
`A. Ding ’979 (EX1006).
`
`Ding ’979, assigned to Allergan, issued December 12, 1995, and is 35
`
`U.S.C. § 102(b) prior art. EX1006-0001. It explains CsA behaves “as an
`
`immunosuppressant” and is useful for “the enhancement or restoring of lacrimal
`
`gland tearing.” Id., 1:10-16, 37-39. It teaches topical CsA ophthalmic emulsions
`
`
`
`
`12
`
`

`

`Petition for Inter Partes Review of U.S. Patent No. 8,685,930 B2
`
`to treat KCS. Id., 5:9-12. Claims 7-8 specifically recite emulsions containing
`
`0.05-0.40% CsA, 0.625-5.00% castor oil, 1.00% polysorbate 80, 0.05% Premulen®
`,
`
`2.20% glycerine, sodium hydroxide, and water, and having a pH range of 7.2-7.6.
`
`Id., 6:27-41; EX1002, ¶¶115-17; EX1003, ¶¶72-75.
`
`Ding ’979 discloses four specific castor oil-based vehicles (Examples 2A-
`
`D). EX1006, 4:44-54. Ding ’979’s CsA-containing emulsions in Example 1 used
`
`the Example 2 vehicles.3 Id., 4:32-54. Example 1’s emulsions use specific CsA
`
`and castor oil percentages across the ranges recited in Ding ‘979 claims 7 and 8
`
`(0.05% - 0.40% CsA and 0.625% - 5.00% castor oil). Id., 4:32-43.
`
`Ding ’979 explicitly teaches a “more preferred” range for the CsA to castor
`
`oil ratio: 0.02-0.12. Example 1’s specific formulations each had a 0.04 or 0.08
`
`ratio. Id., 3:17-20; 4:31-43; EX1002, ¶¶119-20.
`
`Ding ’979 taught the Example 1 formulations “were made for treatment of
`
`keratoconjunctivitis sicca (dry eye) syndrome” and that Examples 2-4 were
`
`prepared without CsA to “determine the toxicity of the emulsified components.”
`
`EX1006, 5:9-14. Ding ’979 reports that the Examples 1A-D formulations, even
`
`when applied eight times a day for seven days, produced at most “slight to mild
`
`discomfort” or “slight hyperemia”; and as between the formulation/vehicle ranges
`
`
`3 Example 2C’s vehicle is identical to the challenged claims’ castor oil vehicle.

`
`tested, there were “no differences in toxicity” and they had comparable ocular
`
`bioavailability. Id., 5:15-28; 3:7-9 (compositions of the invention are “non-
`
`irritating” and “with high comfort level”).
`
`B.
`
`Sall (EX1007).
`
`Sall is prior art under 35 U.S.C. § 102(b). EX1002, ¶¶126-41; EX1003,
`
`¶121. Sall describes Patent Owner’s multi-center, randomized, double-masked
`
`Phase 3 clinical trial assessing the safety and efficacy in KCS treatment of twice-
`
`daily topical ophthalmic administration of 0.05% or 0.10% CsA in a castor oil
`
`emulsion, compared to the emulsion vehicle without CsA. EX1007-0001-02,
`
`0005-06 (figs. 1-4). Sall taught the 0.05% CsA emulsion was safe and effective—
`
`at least as effective as the 0.10% CsA emulsion—resulting in fewer adverse side
`
`effects and CsA blood concentrations below detectible levels. EX1007-0001,
`
`0004-07; EX1002, ¶¶128-39; EX1003, ¶¶65-66, 122. Sall compared the 0.05%
`
`and 0.10% CsA emulsions to the same control vehicle, and reported trough CsA
`
`blood concentrations were undetectable in all 0.05% CsA samples; but quantifiable
`
`in six 0.10% CsA samples. EX1007-0002, 0006-07; EX1002, ¶138; EX1003,
`
`¶115.
`
`Sall noted existing palliative dry eye
`
`treatments, and deemed
`
`its
`
`formulations “the first therapeutic treatment specifically for dry eye disease and a
`
`
`
`
`14
`
`

`

`Petition for Inter Partes Review of U.S. Patent No. 8,685,930 B2
`
`significant breakthrough in the management of this common and frustrating
`
`condition.” EX1007-0007-08.
`
`C. Acheampong (EX1008).
`
`Acheampong is prior art under 35 U.S.C. § 102(b). EX1002, ¶¶142-45;
`
`EX1003, ¶¶70, 150. Acheampong describes a Patent Owner study in which CsA
`
`percentages ranging from 0.05%-0.4% were administered to human patients with
`
`KCS twice a day for three months. EX1008-0004. Acheampong measured CsA
`
`blood concentration at peak and trough levels following topical ophthalmic
`
`administration. Id. CsA was not detected in patients receiving the 0.05% CsA
`
`emulsion. Id., 0004-06.
`
`Even after 12 weeks, the 0.05% CsA formulations’ blood concentrations fell
`
`below the trough concentrations used to monitor patient safety with systemic CsA
`
`therapy. EX1008-0006.
`
`IX. CLAIM CONSTRUCTION.
`
`Under 37 C.F.R. § 42.100(b), claim terms of a challenged patent are
`
`presumed to take on their ordinary and customary meaning based on the broadest
`
`reasonable interpretation (“BRI”) of the claim language in light of the
`
`specification.

`
`Independent claims 1, 13, and 25 recite “wherein” clauses directed to the
`
`intended result of the claimed emulsion, reciting respectively that the emulsion is
`
`“therapeutically effective” in treating KCS, treating dry eye disease, or increasing
