`Opposition to Joinder Motion
`Petitioners Sanofi-Aventis U.S. LLC and Regeneron Pharmaceuticals, Inc.
`
`submit this opposition to the motion for joinder filed by Mylan Pharmaceuticals
`
`Inc. in IPR2016-00710 (the "Mylan IPR," Paper No. 3). Mylan's motion requests
`
`joinder of the Mylan IPR with the instant inter partes review filed by Sanofi and
`
`Regeneron, IPR2015-01624 (the "Sanofi IPR"). Both the Mylan IPR and the
`
`Sanofi IPR relate to the same patent, U.S. Patent No. 6,331,415, which is owned by
`
`Genentech, Inc. and City of Hope ("Patent Owners"). Sanofi and Regeneron
`
`understand that Patent Owners intend to oppose Mylan's joinder motion. Because
`
`joinder would also cause prejudice to Sanofi and Regeneron and to their ability to
`
`prosecute or settle the Sanofi IPR as they see fit without interference from Mylan
`
`or having to seek Mylan's cooperation on so-called "consolidated filings and
`
`discovery," Sanofi and Regeneron respectfully request that the Board deny the
`
`motion.
`
`In its motion, Mylan informs the Board that it will "agree to incorporate its
`
`filings with those of Sanofi and Regeneron into a consolidated filing in the Sanofi
`
`IPR…. Sanofi, Regeneron, and Mylan will be jointly responsible for the
`
`consolidated filings." (Motion for Joinder, at 6.) Moreover, Mylan states that
`
`"[c]onsolidated discovery is also appropriate given that Mylan, Sanofi, and
`
`Regeneron are using the same expert declaration in the two proceedings. Mylan,
`
`Sanofi, and Regeneron will designate an attorney to conduct the cross-examination

`of any given witness produced by Genentech and City of Hope, and the redirect of
`
`any given witness produced by Mylan, Sanofi, and Regeneron…." (Id. at 6-7.)
`
`Sanofi and Regeneron oppose Mylan's motion because joinder on these
`
`terms would prejudice Sanofi and Regeneron by unilaterally requiring them to
`
`cooperate with Mylan—a cooperation that Mylan presumes in its motion without
`
`having ever received the concurrence of Sanofi and Regeneron. Sanofi and
`
`Regeneron should not be forced to accommodate the interests of a third party in
`
`determining the prosecution strategy of their own inter partes review and the
`
`potential for settlement. However, Mylan's "conditions" for joining the Sanofi IPR
`
`require exactly that: Mylan has proposed "consolidated" (not unilateral) filings,
`
`which would require that Sanofi, Regeneron and Mylan be "jointly responsible" for
`
`any filings. Similarly, Mylan inserts itself without agreement from Sanofi and
`
`Regeneron into decision making regarding discovery: Mylan, Sanofi, and
`
`Regeneron "will designate an attorney to conduct the cross-examination of any
`
`given witness produced by Genentech and City of Hope, and the redirect of any
`
`given witness produced by Mylan, Sanofi, and Regeneron…."
`
`But Sanofi and Regeneron alone will determine the content of their
`
`remaining filings in the Sanofi IPR. Likewise, Sanofi and Regeneron will choose
`
`who conducts the cross-examination of the witnesses offered by Patent Owners in
`
`the Sanofi IPR. And Sanofi and Regeneron—not Mylan—will designate the
`
`AMECURRENT 720181653.1

`attorney who will take the redirect testimony of their own expert witness (Dr.
`
`Jefferson Foote). To be clear, Sanofi and Regeneron will not cede to Mylan any
`
`control over the conduct or strategy of the Sanofi IPR, Mylan's stated conditions
`
`for joinder notwithstanding. Under similar facts, the Board has denied a second-
`
`filer's joinder motion premised on assumed (but not actual) consent from the
`
`original petitioner on cooperative filings and discovery. See Teva Pharmaceuticals
`
`USA Inc. v. ViiV Healthcare Co., IPR2015-00550, Paper No. 11, at 5-6; Samsung
`
`Electronics Co. v. Arendi S.A.R.L., IPR2014-01142, Paper No. 11, at 4-5.
`
`Finally, consideration of joinder will necessarily slow the proceedings in the
`
`Sanofi IPR as the Board assesses Mylan's request for joinder and the oppositions to
`
`it. The Sanofi IPR is now in the Patent Owners' discovery period, with the
`
`deposition of Dr. Foote already scheduled for April 21, 2016—before Mylan's reply
`
`papers would be due and before the Board will likely rule on the joinder motion.
`
`For these reasons, Sanofi and Regeneron request that the Board deny Mylan's
`
`motion for joinder.
