`

`

`Apotex Inc. (“Petitioner”) petitions for inter partes review (“IPR”) under 35
`
`U.S.C. §§ 311–319 and 37 C.F.R. §§ 42 et seq., seeking cancellation of claims 1-14
`
`and 26-30 (the “Challenged Claims”) of U.S. Patent No. 11,253,572 (“‘572 patent”)
`
`(Ex.1001), assigned to Regeneron Pharmaceuticals, Inc. (“Regeneron” or “Patent
`
`Owner”).
`
`I.
`
`INTRODUCTION
`The Challenged Claims are directed to a method of treating a known
`
`indication with a known dosage regimen of a known active ingredient. Long before
`
`the patent’s alleged 2011 priority date, Regeneron had disclosed that it’s age-related
`
`macular degeneration (“AMD”) clinical trials (VIEW1/VIEW2) with EYLEA®
`
`(aflibercept) were designed to use the precise dosing regimen now covered by the
`
`Challenged Claims. Regeneron publicly disclosed the exact dosing regimen as early
`
`as 2008, three years prior to filing its patent application. While Regeneron added
`
`certain efficacy endpoints that result upon administering the claimed dosage
`
`regimen, such claim elements are not given patentable weight. But even if they
`
`were, the prior art nevertheless anticipates the Challenged Claims.
`
`The caselaw is clear here. It is not patentable to merely observe the efficacy
`
`of administering a known compound using a known method to treat a known
`
`condition. See, e.g., In re Montgomery, 677 F.3d 1375, 1381 (Fed. Cir. 2013); King
`
`Pharms., Inc. v. Eon Labs, Inc., 616 F.3d 1267, 1275 (Fed. Cir. 2010); In re

`

`Omeprazole Patent Litig., 483 F.3d 1364, 1373 (Fed. Cir. 2007); Perricone v.
`
`Medicis Pharm. Corp., 432 F.3d 1368, 1378 (Fed. Cir. 2005); Bristol–Myers Squibb
`
`Co. v. Boehringer Ingelheim Corp., 86 F. Supp. 2d 433, 443 (D.N.J. 2000), aff'd in
`
`relevant part, 246 F.3d 1368 (Fed. Cir. 2001). Simply put, the Challenged Claims
`
`are not patentable.
`
`II. MANDATORY NOTICES (37 C.F.R. § 42.8)

`Petitioner certifies that the ‘572 patent—which issued on February 22, 2022—
`
`is available for IPR and that Petitioner is not barred or estopped from requesting an
`
`IPR challenging any claim thereof on the grounds identified herein. Neither
`
`Petitioner nor any other real party-in-interest has filed a civil action challenging the
`
`5
`
`Celltrion Exhibit 1008
`Page 16
`
`

`

`validity, or been served with a complaint alleging infringement, of the ‘572 patent,
`
`more than one year prior to the filing of this Petition. See Motorola Mobility LLC v.
`
`Arnouse, No. IPR2013-00010, 2013 WL 12349001, *3 (P.T.A.B. Jan. 30, 2013).
`
`V. THE BOARD SHOULD NOT EXERCISE ITS DISCRETION TO
`DENY INSTITUTION
`The Board should not exercise its discretion to deny institution based on the
`
`mere citation by the Applicant of certain references used in this Petition in
`
`Information Disclosure Statements (“IDS”). The examiner’s failure to address any
`
`of the references used in this Petition on the merits favors institution.
`
`To apply §325(d), the Board uses the following two-part framework: “(1)
`
`whether the same or substantially the same art previously was presented to the Office
`
`or whether the same or substantially the same arguments previously were presented
`
`to the Office; and (2) if either condition of first part of the framework is satisfied,
`
`whether the petitioner has demonstrated that the Office erred in a manner material
`
`to the patentability of the challenged claims.” Advanced Bionics, LLC v. Med-El
`
`Elektromedizinische Gerate GmbH, IPR2019-01469, Paper 6 at 8 (PTAB Feb. 13,
`
`2020). “An example of material error may include misapprehending or overlooking
`
`specific teachings of the relevant prior art where those teachings impact patentability
`
`of the challenged claims.” Id. at 8 n.9. In applying this two-part framework, the
`
`Board has identified several nonexclusive factors that may be considered (“the
`
`6
`
`Celltrion Exhibit 1008
`Page 17
`
`

`

`Becton factors”). Becton, Dickinson & Co. v. B. Braun Melsungen AG, IPR2017-
`
`01586, Paper 8 at 17-18 (PTAB Dec. 15, 2017). Factors (a), (b), and (d) correspond
`
`to the first part of the framework, and factors (c), (e), and (f) fall within part two of
`
`the framework. Advanced Bionics, at 8-10.
`
`Dixon, Regeneron (8-May-2008), NCT-795, and NCT-377, used in this
`
`Petition as anticipatory references, are merely a few of the hundreds of references
`
`submitted to the Patent Office in various Information Disclosure Statements during
`
`the very short prosecution. Although the examiner acknowledged the IDSs, there is
`
`no evidence that he substantively considered the references relied upon herein. In
`
`fact, the Examiner did not present any rejections based on prior art in the one and
`
`only Office Action, instead only presenting double patenting rejections over several
`
`patents in the same family.
`
`The Board “has consistently declined exercising its discretion under Section
`
`325(d) when the only fact a Patent Owner can point to is that a reference was
`
`disclosed to the Examiner during the prosecution.” Amgen Inc. v. Alexion Pharm.,
`
`Inc., IPR2019-00740, Paper 15 at 65 (PTAB Aug. 30, 2019); Amneal Pharms. LLC
`
`v. Alkermes Pharma Ireland Ltd., IPR2018-00943, slip op. at 40 (PTAB Nov. 7,
`
`2018) (Paper 8) (declining to deny institution based on § 325(d) where reference was
`
`listed on the face of the patent, but patent owner provided no evidence “about the
`
`extent to which the [e]xaminer evaluated” the reference during prosecution); Digital
`
`7
`
`Celltrion Exhibit 1008
`Page 18
`
`

`

`Check Corp. d/b/a ST Imaging v. E-Imagedata Corp., IPR2017-00178, slip op. at
`
`12-13 (PTAB Apr. 25, 2017) (Paper 6) (granting institution even though a prior art
`
`reference was cited in an IDS because there was no indication that the claims were
`
`substantively discussed by the examiner during prosecution); Fox Factory, Inc. v.
`
`SRAM, LLC, IPR2016-01876, slip op. at 7-9 (PTAB Apr. 3, 2017) (Paper 8)
`
`(refusing to deny institution based on § 325(d) when a prior art reference was cited
`
`in an IDS but was not considered by the examiner at any length). This pattern is
`
`particularly consistent where, as here, a relevant reference is merely cited in an IDS
`
`but not applied by the Examiner in making a rejection. See Apotex, Inc. v. UCB
`
`Biopharma, SPRL, IPR2019-00400, Paper 17 at 24-25 (PTAB July 15, 2019).
`
`Petitioner does not contend that Dixon, Regeneron (8-May-2008), NCT-795,
`
`and NCT-377 were not presented to the Office. Thus, the relevant analysis here
`
`relates to part two of the Advanced Bionics framework. Part two of the Advanced
`
`Bionics framework considers whether the petitioner has demonstrated that the Office
`
`erred in a manner material to the patentability of the challenged claims. Advanced
`
`Bionics, at 8. As Advanced Bionics explains, considering Becton factors (c), (e), and
`
`(f) can provide guidance as to whether the Office erred. Roku, Inc. v. Universal
`
`Elecs., Inc., IPR2019-01619, Paper 11 at 12 (PTAB Apr. 2, 2020). As explained
`
`below, each of these factors demonstrate the material error by the Office.
`
`8
`
`Celltrion Exhibit 1008
`Page 19
`
`

`

`Regarding factor (c), there is no evidence that Dixon, Regeneron (8-May-
`
`2008), NCT-795, or NCT-377 were evaluated at all during examination, and it is
`
`indisputable that they were never the basis for a rejection. There is no discussion of
`
`any of these references in the one Office Action in the ’572 patent’s prosecution
`
`history. This factor therefore weighs strongly against exercising § 325(d) discretion.
`
`See Hyperbranch Med. Tech., Inc. v. Confluent Surgical, Inc., IPR2018-01097,
`
`Paper 14 at 24 (PTAB Nov. 14, 2018) (Prior art “simply being of record, but not
`
`applied in any rejection by the Examiner during examination…, provides little
`
`impetus for [the Board] to exercise [its] discretion to deny institution under §
`
`325(d)”); Mylan Pharm. Inc. v. Merck Sharp & Dohme Corp., IPR2020-00040,
`
`Paper 21 at 18 (PTAB May 12, 2020) (finding material error where “[t]he Examiner
`
`never discussed [asserted prior art cited in IDS] or made a rejection based on it”).
`
`Regarding factors (e) and (f), as demonstrated herein, the asserted references
`
`anticipate all but four of the Challenged Claims, and these references, in combination
`
`with a reference that was not before the Office during prosecution (Hecht) renders
`
`obvious the remaining Challenged Claims. Thus, Petitioner has demonstrated that
`
`the Examiner’s failure to consider Dixon, Regeneron (8-May-2008), NCT-795, or
`
`NCT-377 and the disclosures relied on in this Petition constitutes material error. The
`
`Amgen case cited above is highly instructive in this regard. The Board held that the
`
`failure of the examiner to apply prior art that served as the primary reference in an
`
`9
`
`Celltrion Exhibit 1008
`Page 20
`
`

`

`IPR can itself constitute material error. Amgen, IPR2019-00740, Paper 15 at 65.
`
`And, in arriving at that holding, the Board credited five other proceedings where the
`
`Board declined to exercise its discretion under § 325(d) when a reference was
`
`previously disclosed, but never substantively considered by the Examiner. Amneal
`
`Pharms., IPR2018-00943, Paper 8 at 40; Digital Check, IPR2017-00178, Paper 6 at
`
`12–13; Fox Factory, IPR2016-01876, Paper 8 at 7–9; HyperBranch Med. Tech.,
`
`IPR2018-01097, Paper 14 at 17; Praxair Distrib., Inc. v. INO Therapeutics LLC, No.
`
`IPR2015-00893, Paper 14 at 8 (PTAB Sept. 22, 2015).
`
`Furthermore, the Board has consistently held that under these circumstances,
`
`the question of whether an Examiner materially erred under Becton factor (e) cannot
`
`be answered without evaluating whether the prior art challenge presented in the
`
`Petition demonstrates a likelihood of success on the merits. These cases find material
`
`error consistent with factor (e) when such a likelihood has been demonstrated. See
`
`e.g, Skechers U.S.A., Inc. v. Nike, Inc., Paper 10 at 19-20 (PTAB May 19, 2021)
`
`(petitioner demonstrated material error by demonstrating a “reasonable likelihood of
`
`prevailing” in its anticipation argument regarding a reference cited in an IDS but not
`
`substantively considered by the Examiner); HTC Corp. v. Motiva Patents, LLC,
`
`IPR2019-01666, Paper 9 at 10 (PTAB Apr. 3, 2020) (petitioner demonstrated a
`
`material error under the second part of the Advanced Bionics framework when two
`
`references cited in an IDS but not substantively considered by the Examiner during
`
`10
`
`Celltrion Exhibit 1008
`Page 21
`
`

`

`prosecution disclosed all the limitations of the claims). The Board has already
`
`preliminarily evaluated whether Dixon, Regeneron (8-May-2008), NCT-795, and
`
`NCT-377 teach the dosage regimen claimed in the ‘572 patent (as it’s the same
`
`dosage regimen claimed in the ‘338 patent), and found in the affirmative. See
`
`IPR2021-00881, Paper 21, Institution Decision at 28, 32 (November 10, 2021)
`
`(granting institution on claims covering the same dosage regimen based on grounds
`
`using the same prior art).
`
`Accordingly, in view of the material error by the Examiner, the Board should
`
`not exercise its discretion to deny institution.
`
`VI. THRESHOLD REQUIREMENT FOR INTER PARTES REVIEW
`This Petition meets and exceeds the threshold required under 35 U.S.C. §
`
`314(a). For each ground, there is a reasonable likelihood that Petitioner will prevail
`
`with respect to at least one of the Challenged Claims.
