`
`
`
`Regeneron Pharmaceuticals, Inc. (“Patent Owner” or “Regeneron”) submits
`
`this preliminary response pursuant to 35 U.S.C. § 313 and 37 C.F.R. § 42.107 to
`
`Mylan Pharmaceuticals Inc.’s (“Petitioner’s” or “MPI’s”) request for inter partes
`
`review (“IPR”) of claims 1, 3-11, 13-14, 16-24 and 26 (“the Challenged Claims”)
`
`of U.S. Patent No. 9,254,338 (“the ’338 Patent,” Ex. 1001).
`
`I.
`
`INTRODUCTION
`Petitioner is developing a biosimilar of EYLEA® and files this challenge to
`
`invalidate Regeneron’s ’338 Patent, which covers the FDA-recommended dosing
`
`regimen for EYLEA®. Petitioner’s challenge relies entirely on references
`
`disclosing the design of Regeneron’s Phase 3 trials. But Petitioner fundamentally
`
`ignores that there existed great uncertainty as to whether an extended, fixed dosing
`
`regimen (Q8) would work until Regeneron’s Phase 3 clinical trial results showed
`
`that it could. Petitioner also ignores that this same prospective dosing regimen
`
`was before the Examiner during prosecution of the ’338 Patent.
`
`Before EYLEA®, the standard of care for treating angiogenic eye disorders
`
`was monthly intravitreal injections of ranibizumab (Lucentis®), an antibody
`
`fragment that binds Vascular Endothelial Growth Factor (“VEGF”), or monthly
`
`off-label use of bevacizumab (Avastin®), an anti-VEGF antibody. The great
`
`burden of monthly intravitreal injections led to several attempts to decrease the
`
`frequency of injections and physician monitoring. Ex. 1018, 1, and 9-10.
`
`However, existing VEGF inhibitors were ineffective at maintaining vision when
`
`US 169985497v27
`
`1
`
`
`
`dosed on a fixed quarterly basis or on an “as-needed” (pro re nata) basis without
`
`monthly monitoring visits. Ex. 1018, 10; Ex. 1001, 1:55-59; Ex. 2003, 5. Indeed,
`
`before the results of Regeneron’s pivotal Phase 3 trials, no one had demonstrated
`
`that a longer-than-monthly fixed dosing regimen (e.g., eight weeks or longer)
`
`could maintain, let alone improve, vision.
`
`Regeneron’s Phase 3 clinical trial results surprisingly demonstrated that
`
`“remarkably similar improvement in vision and anatomic measures can be
`
`achieved” with less frequent EYLEA® dosing as compared to monthly
`
`ranibizumab injections. Ex. 1018, 10. Having secured the data necessary to
`
`support the eight-week extended dosing regimen of the instant claims, Regeneron
`
`obtained FDA approval for EYLEA® and was awarded the ’338 Patent covering
`
`its recommended dosing regimen. EYLEA®’s duration and ability to extend the
`
`time between injections has made it a life-changing drug and revolutionized the
`
`treatment of angiogenic eye disorders. Given the long-felt need and repeated
`
`failures of others to reduce treatment burden and injection frequency, EYLEA®
`
`has enjoyed great commercial success.
`
`The Petition should be denied for at least the following reasons:
`
`First, Petitioner flouts the Board’s rules by circumventing word count limits
`
`and also by disregarding the particularity requirement of 35 U.S.C. § 312(A)(3),
`
`presenting “catch-all” obviousness arguments that do not differentiate between
`
`seven references and fifteen obviousness theories.

`
`
`
`Second, Petitioner’s challenges rely on substantially the same art that was
`
`previously before the U.S. Patent & Trademark Office (“Office”) and considered
`
`by the Examiner, yet Petitioner does not allege that the Examiner erred in a
`
`manner material to the patentability of the Challenged Claims, warranting
`
`discretionary denial under 35 U.S.C. §§ 325(d) and 314(a).
`
`Third, Petitioner fails to demonstrate that its cited references expressly or
`
`inherently disclose the amino acid or nucleic acid sequence limitations of the
`
`Challenged Claims. Petitioner argues that its cited art inherently discloses
`
`aflibercept and its amino acid and nucleic acid sequences through reference to
`
`“VEGF Trap-Eye.” But Petitioner relies on inference to connect “VEGF Trap-
`
`Eye” and “aflibercept” that the prior art does not support, and the Federal Circuit
`
`has repeatedly held that probabilities are insufficient for anticipation.
`
`Fourth, Petitioner’s anticipation challenges also rely on an erroneous claim
`
`construction that seeks to eliminate the efficacy requirements of the Challenged
`
`Claims and Petitioner never shows that the “method of treating” and “tertiary
`
`dose” limitations, which require efficacy, are disclosed either expressly or
`
`inherently in its cited references.
`
`Fifth, Petitioner relies on Regeneron’s Phase 2 clinical trial results for its
`
`obviousness challenge. But that trial tested a different dosing regimen from that
`
`claimed in the ‘338 Patent and failed to provide the skilled artisan with any
`
`expectation of success — let alone a reasonable one — in practicing the claimed
`
`US 169985497v27
`
`3
`
`
`
`inventions. In fact, those clinical trial results showed just the opposite —that it
`
`was not expected that VEGF Trap-Eye would be effective if dosed at eight-week
`
`intervals. Petitioner also ignores that before the priority date, no one, including
`
`Regeneron, had ever shown that a fixed eight-week (or longer) dosing regimen
`
`could maintain, let alone improve, vision.
`
`II.
`
`THE PETITION SHOULD BE REJECTED FOR
`CIRCUMVENTING THE WORD LIMIT AND OBFUSCATING
`ITS GROUNDS
`A.
`The Petition Violates the Word Limit
`The Petition exceeds the 14,000-word limit (37 C.F.R. § 42.24(a)(1)(i)).
`
`Despite certifying that the word count for its petition is 13,904 words (Pet., Cert.
`
`of Compliance), the Petition’s word count includes only the typed words of the
`
`Petition. The word count ignores words in images of text from the ’338 Patent
`
`specification, including a lengthy passage of text on which Petitioner
`
`substantively relies for its arguments. See e.g., Pet., 12; see also Pet., 9, 29. In
`
`total, Petitioner fails to account for 224 words in text images in the Petition which,
`
`when included, results in a word count of 14,128 words. Petitioner, thus,
`
`disregards the Board’s rules, as evidenced by Petitioner’s use of the same tactic in
`
`its Petition filed in IPR2021-00880. Paper 1. This is a reason to deny institution.
`
`Trial Practice Guide (November 2019) at 40 (“Excessive words in figures,
`
`drawings, or images, deleting spacing between words, or using excessive
`
`acronyms or abbreviations for word phrases, in order to circumvent the rules on
`
`US 169985497v27
`
`4
`
`
`
`word count, may lead to a party’s brief not being considered.”); see Pi-Net Int’l,
`
`Inc. v. JPMorgan Chase & Co., 600 F. App’x 774 (Fed. Cir. 2015) (denying
`
`request to file a corrected brief and dismissing appeal because appellant violated
`
`word count).
`
`The proper remedy here is to deny institution, thereby allowing Petitioner to
`
`refile a petition that properly conforms with the Board’s word count rules. No
`
`time bar precludes Petitioner from refiling a petition challenging the ’338 Patent.
`
`The Petition Fails the Particularity Requirement
`B.
`Despite exceeding the allowed word count, Petitioner still has not managed
`
`to state, with particularity, the grounds on which the challenge to each claim is
`
`based. Accordingly, the Petition presents an inefficient use of the Board’s time
`
`and resources, as well as procedural unfairness to Regeneron.
`
`A petition “may be considered only if . . . the petition identifies, 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 the
`
`challenge to each claim.” 35 U.S.C. § 312(a)(3); see also Adaptics Ltd. v. Perfect
`
`Co., IPR2018-01596, Paper 20 at 15-24 (Mar. 6, 2019) (informative). “[T]he
`
`Board may consider whether a lack of particularity as to one or more of the
`
`asserted grounds justifies denial of an entire petition.” Id. at 17. Furthermore, the
`
`Office Patent Trial Practice Guide advises practitioners to “focus on concise, well-
`
`organized, easy-to-follow arguments supported by readily identifiable evidence of
`
`US 169985497v27
`
`5
`
`
`
`record.” 77 Fed. Reg. 48756, 48763 (August 14, 2012).
`
`Here, Petitioner does not satisfy the particularity requirements under
`
`§ 312(a)(3) for at least Ground 6 because the Petition suffers from the same
`
`deficiencies identified by the Board in Adaptics. Specifically, Ground 6 is a
`
`“catch-all” ground that alleges that the Challenged Claims are obvious over seven
`
`references under fifteen different theories:
`
`1. Dixon;
`
`2. Dixon + the ’758 Patent;
`
`3. Dixon + Dix;
`
`4. Adis;
`
`5. Adis + the ’758 Patent;
`
`6. Adis + Dix;
`
`7. Regeneron (8-May-2008);
`
`8. Regeneron (8-May-2008) + the ’758 Patent;
`
`9. Regeneron (8-May-2008) + Dix;
`
`10.NCT-795;
`
`11.NCT-795 + the ’758 Patent;
`
`12.NCT-795 + Dix;
`
`13.NCT-377;
`
`14.NCT-377 + the ’758 Patent;
`
`6
`
`US 169985497v27
`
`
`
`15.NCT-377 + Dix.
`See Pet., 62.
`
`Petitioner asserts that five references (Dixon, Adis, Regeneron (8-May-
`
`2008), NCT-795, and NCT-377) are interchangeable. Id. at 62 n.12. Petitioner
`
`does not explain why all five are necessary for this obviousness ground, nor how
`
`each combination differs from the others. Rather, these five references are cited
`
`for the disclosure of the same alleged feature. This is at odds with the Office’s
`
`direction to “avoid submitting a repository of all the information that a judge
`
`could possibly consider,” and inundates the Board with excessive references for
`
`its consideration. 77 Fed. Reg. at 48763.
`
`Furthermore, Petitioner only addresses Dixon in Ground 6 and relegates the
`
`other four primary references and fifteen different obviousness theories to a
`
`footnote. Pet., 62 n.12. This leaves the Board and Regeneron to fill in the gaps of
`
`the Petition. Regeneron is at an unfair disadvantage of having to guess which
`
`theories Petitioner will pursue, what evidence allegedly supports those theories,
`
`and what purported motivations and reasonable expectation of success Petitioner
`
`might advance were trial instituted.
`
`As each theory constitutes a distinct ground, Petitioner impermissibly shifts
`
`the burden to the Board and Regeneron to understand the multiplicity of
`
`obviousness grounds presented. For at least the reasons above, Regeneron
`
`respectfully requests denial of the petition under 35 U.S.C. § 314(a).
`
`US 169985497v27
`
`7
`
`
`
`Janssen Pharmaceuticals, Inc. Is a Real Party-in-Interest
`C.
`Petitioner also fails to identify the correct RPIs in its Petition. Petitioner
`
`identifies Viatris Inc., Mylan Inc., Mylan Pharmaceuticals Inc., Momenta
`
`Pharmaceuticals, Inc., and Johnson & Johnson as real parties-in-interest to the
`
`instant Petition. Pet., 4. Petitioner states “[n]o other parties exercised or could
`
`have exercised control over this Petition; no other parties funded, directed and
`
`controlled this Petition.” Id. However, Regeneron understands from publicly
`
`available documents that Janssen Pharmaceuticals, Inc. (“Janssen”) is a real party-
`
`in-interest for the same reasons Mylan disclosed these other entities. Multiple
`
`Johnson & Johnson press releases and Securities Exchange Commission filings
`
`indicate that Janssen, a pharmaceutical company headquartered in Beerse,
`
`Belgium, and owned by Johnson & Johnson, is managing the business and
`
`operations of Momenta, generally, and the acquired Momenta pipeline of clinical
`
`and pre-clinical assets, including a biosimilar to EYLEA®. Ex. 2004, 46 (“the
`
`business and operations of Momenta will be managed as one of the Janssen
`
`Pharmaceuticals Companies of Johnson & Johnson.”); see also Ex. 2005; Ex.
`
`2006.
`
`While denial of institution is warranted here, if the Board grants institution,
`
`it should require Petitioner to file updated mandatory disclosures identifying
`
`Janssen as a real party-in-interest.

`
`III. THE BOARD SHOULD DENY INSTITUTION UNDER
`35 U.S.C. § 325(D)
`The Board should exercise its discretion and deny institution under 35
`
`U.S.C. § 325(d) because Petitioner relies on substantially the same art that was
`
`already considered by the Examiner during prosecution of the ’338 Patent, and
`
`fails to argue that the Examiner made any error material to the patentability of the
`
`Challenged Claims in considering that art.
`
`A.
`
`Petitioner Mischaracterizes the Prosecution History of the ’338
`Patent and its Foreign Counterpart
`Petitioner repeatedly and baselessly attempts to cast doubt on Regeneron’s
`
`candor with the Office. Specifically, Petitioner incorrectly asserts that “none of
`
`the numerous pre-2011 publications disclosing the VIEW1/VIEW2 dosing
`
`regimens . . . were submitted to or cited by the Examiner during prosecution.”
`
`Pet., 27. This is incorrect. To the contrary, Regeneron’s VIEW1/2 dosing
`
`regimens were before the Examiner and considered during prosecution of the ’338
`
`Patent. On October 18, 2013, Regeneron presented a September 28, 2008,
`
`Regeneron Press Release (“9/28/2008 Press Release”) to the Office in an IDS,
`
`which was marked considered by the Examiner. Ex. 1017, 60 and 277. The
`
`9/28/2008 Press Release discloses the same VIEW1/2 prospective dosing regimen
`
`that Petitioner relies on in Grounds 1-5 of its Petition. Ex. 2007, 1; see Section
`
`III.B, infra.
`
`In addition, Petitioner asserts that Regeneron never cited art from EP-325
`
`(the European counterpart to the ’338 Patent) to the Examiner of the ’338 Patent
`
`US 1
