`
`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 and 8-12 (“Challenged Claims”) of U.S. Patent No.
`
`9,669,069 (“the ’069 Patent,” Ex. 1001).
`
`I.
`
`INTRODUCTION
`Petitioner, who is developing a biosimilar of EYLEA® for the treatment of
`
`angiogenic eye disorders, files this challenge to try to invalidate Regeneron’s ’069
`
`Patent, which covers an alternate approved dosing regimen for EYLEA®.
`
`Before the development of EYLEA®, the standard of care for treatment of
`
`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 injections led to several attempts to
`
`increase intervals between injections. Ex. 1018, 1 and 9. However, existing
`
`VEGF inhibitors were not effective at maintaining vision through fixed quarterly
`
`or “as needed” (pro re nata) dosing regimens. Ex. 1001, 1:55-59; Ex. 2003, 5.
`
`Regeneron sought to develop a therapy that would finally improve and
`
`maintain visual acuity with extended time between injections. The ’069 Patent
`
`discloses and claims the administration of a specific VEGF antagonist using a
`
`dosing regimen that includes a single initial dose of the VEGF antagonist,
`
`US 169984423v25
`
`1
`
`
`
`followed by one or more secondary doses of the VEGF antagonist, followed by
`
`one or more tertiary doses of the VEGF antagonist, where the tertiary doses are
`
`“administered on an as-needed/pro re nata (PRN) basis, based on visual and/or
`
`anatomical outcomes as assessed by a physician or other qualified medical
`
`professional.”
`
`As set forth herein and in the accompanying exhibits, the Petition should be
`
`denied for at least the following independent reasons:
`
`First, Petitioner flouts the Board’s rules by circumventing word count limits
`
`and by disregarding the particularity requirement of 35 U.S.C. § 312(a)(3),
`
`presenting “catch-all” obviousness arguments that do not differentiate between six
`
`references and nine obviousness theories.
`
`Second, Petitioner bases its challenges on the same or substantially the
`
`same prior art that was previously before the U.S. Patent & Trademark Office
`
`(“Office”) and was 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 makes no effort to show that the art relied upon in any of
`
`its Grounds discloses, expressly or inherently, that the PRN dosing of the claimed
`
`VEGF Trap fusion protein be administered “based on visual and/or anatomical
`
`outcomes as assessed by a physician or other qualified medical professional.”
`
`Instead, Petitioner argues — unconvincingly — that this limitation is a “mental
`
`US 169984423v25
`
`2
`
`
`
`step” that should be afforded no patentable weight. Because Petitioner’s claim
`
`construction position lacks merit and it has utterly failed to show this limitation in
`
`its cited art, it has not met its threshold burden under 35 U.S.C. §§ 314(a) and
`
`312(a)(3), and the Board should deny institution for this reason alone.
`
`Fourth, Petitioner’s anticipation challenges also fail because Petitioner does
`
`not demonstrate that the claims’ required nucleic acid or amino acid sequence was
`
`expressly or inherently disclosed in its cited references. Petitioner’s anticipation
`
`position depends on its unsupported theory that the alleged prior art inherently
`
`discloses aflibercept and its amino acid and nucleic acid sequences through
`
`reference to “VEGF Trap-Eye.” But Petitioner relies on inference to make a
`
`connection between “VEGF Trap-Eye” and “aflibercept” that the prior art does
`
`not support, and the Federal Circuit has repeatedly held that such mere
`
`possibilities or probabilities are insufficient for anticipation.
`
`Fifth, Petitioner’s Ground 4 anticipation and obviousness challenges
`
`additionally fail because its cited art fails to disclose a “tertiary dose” that “is
`
`administered on an as-needed/pro re nata PRN basis” and, further, Petitioner fails
`
`to show that the person of ordinary skill in the art (“POSA”) would have been
`
`motivated to modify a fixed 8-week tertiary dosing regimen to become a PRN
`
`tertiary dosing regimen, as required by each of the Challenged Claims.
`
`Finally, Petitioner’s Ground 5 obviousness challenge additionally should be
`
`rejected because Petitioner fails to show that the POSA would have been
`
`US 169984423v25
`
`3
`
`
`
`motivated to reduce the four monthly loading doses1 in Regeneron’s Phase 2
`
`clinical trials to three monthly loading doses, and further fails to address that the
`
`clinical trial results and the art as a whole would caution against such a
`
`modification.
`
`For these reasons, as explained further below, Regeneron respectfully
`
`requests that the Board deny institution of the Petition.
`
`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 13,951 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 ’069 Patent
`
`specification, including a lengthy passage of text on which Petitioner
`
`substantively relies for its arguments. See e.g., Pet., 14-15. In total, Petitioner
`
`fails to account for 186 words in text images in the Petition which, when included,
`
`results in a word count of 14,137 words. Thus, Petitioner disregards the Board’s
`
`rules, as further evidenced by Petitioner’s use of the same tactic in its Petition
`
`filed in IPR2021-00881. Paper 1. This is a reason to deny institution. Trial
`
`1 The recited initial and secondary doses are also referred to as “loading doses” and
`
`the recited tertiary doses are also referred to as “maintenance doses” herein.
`
`US 169984423v25
`
`4
`
`
`
`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 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 ’069 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
`
`US 169984423v25
`
`5
`
`
`
`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
`
`record.” 77 Fed. Reg. 48756, 48763 (August 14, 2012).
`
`Here, Petitioner has not satisfied the particularity requirements under
`
`§ 312(a)(3) for at least Ground 5 because the Petition suffers from the same
`
`deficiencies identified by the Board in Adaptics. Specifically, Ground 5 is a
`
`“catch-all” ground that alleges that the Challenged Claims are obvious over six
`
`references under at least seven and as many as nine different theories:
`
`1. Heier-2009 + Mitchell;
`
`2. Heier-2009 + Mitchell + the ’758 Patent;
`
`3. Heier-2009 + Mitchell + Dix;
`
`4. Heier-2009 + Dixon;
`
`5. Heier-2009 + Dixon + the ’758 Patent;
`
`6. Heier-2009 + Dixon + Dix;
`
`7. Heier-2009 + Lalwani;
`
`8. Heier-2009 + Lalwani + the ’758 Patent; and
`
`9. Heier-2009 + Lalwani + Dix.
`
`See Pet., 60-61 n.22.
`
`Importantly, Petitioner fails to explain why each of these combinations is
`
`necessary. Id. at 60-67. Rather, as in Adaptics, Petitioner impermissibly assumes
`
`US 169984423v25
`
`6
`
`
`
`that Heier-2009 does not disclose one or more claim limitations and leaves it to
`
`the Board and Regeneron to fill in the gaps of its Petition. Petitioner also does not
`
`explain the differences between at least independent claim 1 and the alleged
`
`primary reference, Heier-2009, much less the other secondary or tertiary
`
`references, or the differences between each of the various secondary references
`
`(Mitchell, Dixon, Lalwani) or between each of the various tertiary references
`
`(the ’758 Patent and Dixon). Id. at 63-66. Consequently, as in Adaptics,
`
`Petitioner turns the Petition into an empty invitation to the Board and Regeneron
`
`to ascertain what evidence purportedly supports the full breadth of Petitioner’s
`
`contentions.
`
`Beyond its failure to identify how each combination maps to the claim
`
`limitations or the differences between each combination, Petitioner does not
`
`articulate any specific motivation to combine or modify at least: (1) Heier-2009
`
`with Lalwani, (2) the Heier-2009 and Mitchell combination with either of the two
`
`tertiary references, or (3) the Heier-2009 and Dixon combination with either of the
`
`two tertiary references. Again, this lack of particularization leaves Regeneron and
`
`the Board to search the record for the evidence that would support Petitioner’s
`
`theories.
`
`Compounding Petitioner’s lack of specificity as to the distinct combinations
`
`comprising Ground 5, Petitioner uses its cited references inconsistently. Three of
`
`the seven obviousness theories Petitioner sets out in Ground 5 involve combining
`
`US 169984423v25
`
`7
`
`
`
`Heier-2009 (Ex. 1020) with Dixon (Ex. 1006), even though these two references
`
`are characterized elsewhere in the Petition as alternative references. Compare
`
`Pet., 60-67 (Ground 5) (arguing Heier-2009 and Dixon must be combined) with
`
`Pet., 45-50 (Grounds 1 & 2) (arguing Heier-2009 and Dixon both independently
`
`anticipate). Specifically, Petitioner argues that each of Heier-2009 and Dixon
`
`represent alternative disclosures anticipating claim 1. Id. at 46 (“[E]ach of Heier-
`
`2009 and Dixon disclose every element of independent claim 1.”); see also, id. at
`
`61-62 n.23 (“[B]oth Heier-2009 and Dixon are directed toward and expressly
`
`disclose VEGF Trap-Eye.”). Yet, in Ground 5, Petitioner asserts Heier-2009 and
`
`Dixon in combination disclose all the elements of claim 1. Id. at 62-66 (“A
`
`skilled artisan naturally would have been motivated to combine the successful
`
`PRN regimen of CLEAR-IT-2 from Heier-2009 with the widely used loading
`
`regimen of three monthly doses disclosed in Mitchell and Dixon—to arrive at a
`
`regimen falling squarely within Challenged Claim 1.”); see also, id. at 68-69
`
`(“Heier-2009 plus Dixon”).
`
`This inconsistency as to whether Heier-2009 and Dixon are alternative
`
`references anticipating the Challenged Claims or are cumulative references that
`
`render the Challenged Claims obvious in combination makes Petitioner’s
`
`arguments impermissibly ambiguous and difficult to understand. The Board has
`
`previously deemed similar confusing and inconsistent arguments to lack
`
`particularity and has exercised its discretion to deny the entire Petition under these
`
`US 169984423v25
`
`8
`
`
`
`circumstances. See, e.g., EIK Eng’g Sdn. Bhd. v. Wilco Marsh Buggies &
`
`Draglines, Inc., IPR2020-00344, Paper 7 at 2 (June 23, 2020), reh’g denied,
`
`IPR2020-00344, Paper 12 (Mar. 4, 2021).
`
`For at least the above reasons, Petitioner has not satisfied the requirement to
`
`state, with particularity, the grounds on which the challenge to each claim is
`
`based. Accordingly, the Petition presents procedural unfairness to Regeneron, as
`
`well as an inefficient use of the Board’s time and resources. Consequently,
`
`Regeneron respectfully requests denial of the petition under 35 U.S.C. § 314(a).
`
`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., 4-5. Petitioner stated “[n]o other parties exercised or could
`
`have
