`
`INTRODUCTION
`I.
`Sun Pharmaceutical Industries Ltd. (“Petitioner”), 1 on June 12, 2020,
`filed a Petition for inter partes review of claims 1–4, 17, 19, and 21–23 of
`U.S. Patent No. 7,326,708 B2 (Ex. 1001, “the ’708 patent”). Paper 3 (“Pet.”
`or “Petition”). Petitioner also filed a Motion for Joinder (Paper 2, “Mot.” or
`“Motion”) with Mylan Pharmaceuticals Inc. v. Merck Sharp & Dohme
`Corp., IPR2020-00040, in which Mylan is challenging the patentability of
`those same claims of the ’708 patent (“Mylan IPR”). We instituted inter
`partes review of the Mylan IPR on May 12, 2020. Mylan IPR, Paper 21.
`On July 10, 2020, Merck Sharp & Dohme Corp. (“Patent Owner” or
`“Merck”) filed an Opposition (“Opp.” or “Opposition”) to Petitioner’s
`Motion for Joinder. Paper 7. Petitioner filed a Reply in support of the
`Motion. Paper 9 (“Mot. Reply”). And, on August 14, 2020, Patent Owner
`filed a Preliminary Response to the Petition. Paper 11 (“Prelim. Resp.”).
`
`A. Related Proceedings
`The parties identify several proceedings where the ’708 patent is
`being asserted, including: Merck Sharp & Dohme Corp. v. Mylan Pharm.
`Inc. et al., 1:19:-cv-00101 (N.D. W. Va); Merck Sharp & Dohme Corp. v.
`Mylan Pharm. Inc. et al., 1:19-cv-01489 (D. Del.); Merck Sharp & Dohme
`Corp. v. Sun Pharmaceutical Industries Ltd., 1:19-cv-00319 (D. Del); Merck
`Sharp & Dohme Corp. v. Watson Pharmaceuticals, Inc., 1:19-cv-00317 (D.
`Del.), Merck Sharp & Dohme Corp. v. Teva Pharmaceuticals USA, Inc.,
`
`1 Petitioner identifies Sun Pharmaceutical Industries Ltd. and Sun
`Pharmaceutical Industries, Inc. as the real parties-in-interest. Pet. 6.

`
`IPR2020-01072
`Patent 7,326,708 B2
`
`1:19-cv-00318 (D. Del.); and Merck Sharp & Dohme Corp. v. Dr. Reddy’s
`Laboratories Ltd., 1:20-cv-00847 (D. Del.). Pet. 6–7 (listing cases); Paper
`5, 2–3 (Patent Owner’s Mandatory Notices). As Merck has explained, its
`lawsuits against several generic drug companies related to the ’708 patent,
`including suits identified above, have been consolidated for pretrial purposes
`in a multidistrict litigation. See Mylan IPR, Paper 10, 10 (identifying In re
`Sitagliptin Phosphate (’708 & ’921) Patent Litig. C.A. No. 19-md-2902-
`RGA (D. Del.)).
`In addition to the Mylan IPR, Patent Owner identifies the following
`related administrative matters pending before the Patent Office: Teva
`Pharmaceuticals USA, Inc. v. Merck Sharp & Dohme Corp., IPR2020-
`01045; and Dr. Reddy’s Laboratories, Inc. v. Merck Sharp & Dohme Corp.,
`IPR2020-01060. Paper 5, 3. 2
`
`
`2 Petitioners in these related matters filed their petitions at or about the same
`time as the present Petition. Those other petitioners similarly move for
`joinder with the Mylan IPR. See, e.g., IPR2020-1060, Paper 3.

`
`Petitioner also cites the declaration of Dr. Steven Baldwin (Ex. 1002),
`but has indicated that it will withdraw Dr. Baldwin’s declaration, and will
`rely instead on the testimony of Mylan’s declarant, Dr. Mukund Chorghade,
`in the Mylan IPR if permitted. Mot. 4.
`
`II.
`
`INSTITUTION OF INTER PARTES REVIEW
`
`The Petition advances the same grounds of unpatentability that are
`included in the instituted Mylan IPR. Compare Pet. 13–71, with Mylan IPR,
`Paper 1, 12–69; see also Mylan IPR, Paper 21, 4–5, 64 (Institution
`Decision). Indeed, Petitioner “asserts that the same claims are invalid based
`on substantially the same arguments presented in the Mylan IPR,” and that
`“Petitioner’s declaration is substantively identical to the declaration in the
`Mylan IPR.” Mot. 1; see also id. at 4 (“Along with its Motion for Joinder,
`Petitioner here has simultaneously filed a ‘me too’ Petition” for IPR based
`on the “same reasons set forth in the Mylan IPR.”). We conclude the
`Petition is properly characterized as a “me-too” challenge relative to the
`petition in the Mylan IPR.
`Merck filed a Preliminary Response, agreeing that “[t]he Petition at
`issue is a ‘Me-Too’ petition,” that was filed with a timely motion for joinder.
`Prelim. Resp. 1.8 Merck notes the preliminary arguments it raised in
`response to the petition in the Mylan IPR. Id. But, recognizing that the
`Board granted institution in the Mylan IPR notwithstanding those
`
`
`8 Patent Owner’s Preliminary Response does not include page numbers, but
`we treat as though it includes pages 1–4, with page 1 beginning after the
`caption page.
`
`5
`
`
`
`IPR2020-01072
`Patent 7,326,708 B2
`
`arguments, Merck, “[f]or efficiency and to conserve judicial resources,”
`does not specifically raise or restate those arguments at this time. Id. at 2–3
`(reserving its rights to make argument and address the grounds further in any
`instituted and/or joined trial proceeding).
`We grant joinder as explained below, and because we determined that
`the preliminary arguments raised by Patent Owner in the Mylan IPR were
`insufficient to avoid institution in that case, we likewise grant institution
`here. 9 For the reasons set forth in our Institution Decision in the Mylan IPR,
`we determine that Petitioner has met its burden to demonstrate a reasonable
`likelihood that it would prevail in showing at least one of the challenged
`claims are unpatentable. See generally Mylan IPR, Paper 21. Accordingly,
`we institute inter partes review on the grounds raised by Petitioner here,
`which are the same as in the instituted Mylan IPR.
`
`III. GRANT OF MOTION FOR JOINDER
`As discussed above, we instituted trial in the Mylan IPR on May 12,
`2020. Mylan IPR, Paper 21. Petitioner filed its Motion for Joinder on June
`12, 2020, and the motion is, therefore, timely. 37 C.F.R. § 42.122(b) (2020)
`(requiring any joinder motion be filed “no later than one month after the
`institution date of any inter partes review for which joinder is requested”).
`
`
`9 Because we grant joinder, we do not reach Patent Owner’s alternative
`argument that the Petition is time barred under 35 U.S.C. § 315(b). Prelim.
`Resp. 3; 37 C.F.R. § 42.122(b) (“The time period set forth in § 42.101(b)
`[related to the one-year time bar under 35 U.S.C. § 315(b)] shall not apply
`when the petition is accompanied by a request for joinder.”); see also
`35 U.S.C. § 315(c).
`
`6
`
`
`
`IPR2020-01072
`Patent 7,326,708 B2
`
`The statutory provision governing joinder in inter partes review
`proceedings is 35 U.S.C. § 315(c), which reads:
`If the Director institutes an inter partes review, the Director, in
`his or her discretion, may join as a party to that inter partes
`review any person who properly files a petition under section 311
`that the Director, after receiving a preliminary response under
`section 313 or the expiration of the time for filing such a
`response, determines warrants the institution of an inter partes
`review under section 314.
`Furthermore, a motion for joinder should (1) set forth reasons why
`joinder is appropriate; (2) identify any new grounds of unpatentability
`asserted in the petition; (3) explain what impact (if any) joinder would have
`on the trial schedule for the existing review; and (4) address specifically how
`briefing and discovery may be simplified. See Kyocera Corp. v. Softview
`LLC, IPR2013-00004, Paper 15, (PTAB Apr. 24, 2013). Petitioner
`addresses these considerations in its Motion, and we generally agree with
`Petitioner’s assertions in favor of joinder. Mot. 4–9. We discuss further
`below.
`The Petition raises the same unpatentability grounds on which we
`instituted review in the Mylan IPR, and no others. Mot. 4 (“The grounds
`proposed in the present Petition are therefore the same grounds of
`unpatentability on which the Board instituted the Mylan IPR, and the
`Petition does not contain any additional arguments or evidence (except for
`reliance on a different expert [offering identical opinions], as noted above.”).
`Patent Owner provides no persuasive argument to the contrary. Thus, this
`inter partes review does not present any ground not already at issue in the
`Mylan IPR.
`
`7
`
`
`
`IPR2020-01072
`Patent 7,326,708 B2
`
`Petitioner’s challenge to the ’708 patent is “substantively identical” to
`the challenge presented in the Mylan IPR. Mot. 1. Moreover, Petitioner
`persuades us that it has agreed to play the role of a true and silent
`“understudy” to Mylan in the joined proceeding—agreeing to conditions like
`those regularly cited in other Board cases where joinder of a me-too petition
`was granted. Mot. 4, 6–7 (agreeing, for example, to rely on and be bound by
`the testimony of Mylan’s expert); see also Mot. Reply 2–3 (identifying
`conditions that the parties have agreed to with respect to Petitioner’s role in
`the joined proceeding). Petitioner’s limited role in the joined proceeding
`helps to streamline matters and mitigate inefficiencies so that the Board can
`focus on the merits in reaching a final written decision that addresses the
`same patentability challenges raised here and in the Mylan IPR. These
`considerations favor joinder.
`Patent Owner initially opposed joinder, arguing that Petitioner’s role
`in the proceeding was uncertain and that Petitioner had not agreed to play
`the role of a true understudy. Opp. 11–15. Later, however, the parties
`apparently reached agreement on the conditions of Petitioner’s participation
`if joined as a party. See Mot. Reply 1–2 (“Correspondence already of record
`shows that Joinder Petitioners [which include Petitioners here and petitioners
`in IPR2020-01045 and IPR2020-1060] explicitly agreed to Merck’s
`conditions”); see also Mylan IPR, Ex. 1018, 9:1–4 (Patent Owner’s counsel
`representing that “Merck can report that we see that there is agreement
`amongst Merck and the Joinder Petitioners on the understudy role that the
`
`8
`
`
`
`IPR2020-01072
`Patent 7,326,708 B2
`
`Joinder Petitioners would play.”). 10 Petitioner persuades us its participation
`will be limited to that of the silent understudy, and we appreciate the parties’
`efforts to reach agreement in that regard.
`As to joinder’s potential impact on the existing trial and briefing
`schedule, based on the facts known to us at present, we conclude that such
`impact is likely to be insubstantial and otherwise manageable. Mot. 6–7.
`For example, Petitioner, in its role as silent understudy, is not permitted to
`make its own filings in the Mylan IPR, nor may it pursue discovery from
`Patent Owner, or provide its own argument at oral hearing (if requested). To
`the contrary, Mylan is the lead petitioner, and Petitioner will be bound in this
`proceeding by the papers filed and representations made by Mylan in the
`Mylan IPR. 11 Petitioner’s agreement to withdraw the declaration of their
`own expert will also help streamline discovery here. Id. at 2–3.
`In its Opposition, Merck states that it “opposes joinder to the extent it
`precludes Merck from discovery to which it is otherwise entitled from
`Joinder Petitioners.” Opp. at 3–8. 12 Merck then cites an application for
`
`10 Exhibit 1018 in the Mylan IPR is a transcript of an August 10, 2020,
`conference call between the Board and counsel for the parties in IPR2020-
`00040, IPR2020-01045, IPR2020-01060, and IPR2020-01072.
`11 Although Petitioners are bound by all substantive filings made by Mylan,
`that does not extend to filings or representations unique to Mylan, such as
`matters related to potential or actual settlement.
`12 We agree with Petitioner that the cases cited by Patent Owner on this point
`are inapposite. Mot. Reply 4. The discovery issue in Unified Patents related
`to a dispute about identification of all real parties-in-interest, and in ZTE the
`joinder petitioner did not file an identical petition—in each case, injecting
`new and substantive party-specific issues. See Unified Patents, Inc. v.
`
`9
`
`
`
`IPR2020-01072
`Patent 7,326,708 B2
`
`patent filed by Petitioner that includes disclosure that Patent Owner contends
`is inconsistent with Petitioner’s characterization of a prior art reference
`asserted here. Opp. 7. We need not decide at this point whether Merck is
`entitled to discovery from Petitioner on that particular matter. But Merck is
`not precluded from pursuing it, and, if the parties reach an impasse after
`exhausting good faith efforts, asking for the Board’s help in promptly
`resolving the dispute.
`We also note that, although Merck initially opposed joinder based on
`an alleged need for discovery from Petitioner before the due date for the
`Patent Owner Response in the Mylan IPR, and potential schedule disruption
`without it (Opp. 8–11), Merck more recently signaled that it no longer
`opposed joinder on that basis. Merck indicated it was, instead, reserving its
`right to seek discovery if joinder is ordered. See generally Mylan IPR,
`Ex. 1018, 10:3–12:18. Merck may pursue discovery as noted above. We
`remind the parties, however, that, consistent with the purposes of the Leahy-
`Smith America Invents Act, discovery in IPR proceedings is not the same as
`available in district court and under the Federal Rules of Civil Procedure.
`Consistent with our rules and precedents, IPR discovery is more limited and
`requests must, inter alia, be narrowly targeted to specific documents or
`information. See Garmin Int’l, Inc. v. Cuozzo Speed Tech. LLC, IPR2012-
`
`
`Personalweb Techs., IPR2014-00702, Paper 12, 5 (PTAB July 24, 2014);
`ZTE Corp. v. Adaptix, Inc., IPR2015-01184, Paper 10, 4–6 (PTAB July 24,
`2015). Not so here. Even accepting Patent Owner’s characterization of the
`discovery, it relates to an issue already in the Mylan IPR—the teachings of
`the asserted prior art. See Mylan IPR, Paper 21, 50–53, 55–56.
`10
`
`
`
`IPR2020-01072
`Patent 7,326,708 B2
`
`00001, Paper 26, 3–7 (PTAB Mar. 5, 2013) (precedential) (discussing limits
`with respect to both routine and additional IPR discovery). In sum, we are
`not convinced that discovery issues requiring the Board’s intervention will
`arise. But if they do, there is no adequate basis to conclude that such issues
`cannot be addressed promptly and fairly within the confines of the current
`schedule.
`On balance, we agree with Petitioner that joinder with the Mylan IPR
`is appropriate under the circumstances. Petitioner’s Motion for Joinder is,
`thus, granted.
`
`IV. ORDER
`In consideration of the foregoing, it is hereby:
`ORDERED that, pursuant to 35 U.S.C. § 314(a), inter partes review of
`claims 1–4, 17, 19, and 21–23 of U.S. Patent No. 7,326,708 B2 is instituted

`FURTHER ORDERED that the Motion for Joinder with IPR2020-
`00040 is granted, and Petitioner is joined as a party to IPR2020-00040;
`FURTHER ORDERED that all further filings by Petitioner and Patent
`Owner, except for those which concern a request for rehearing of this
`decision, shall be made only in IPR2020-00040;
`FURTHER ORDERED that, subsequent to joinder, the grounds and
`claims for trial in IPR2020-00040 remain unchanged;
`FURTHER ORDERED that, subsequent to joinder, the Scheduling
`Order for IPR2020-00040 (Papers 22 and 39) remains unchanged, subject to
`any change already made by stipulation between the parties or otherwise

`
`11
`
`
`
`IPR2020-01072
`Patent 7,326,708 B2
`
`FURTHER ORDERED that Petitioner shall, absent the Board’s

`with Patent Owner, and a Motion to Terminate Mylan from the joined
`proceeding has been filed by Mylan, or (2) the filing is a motion to terminate
`the proceeding with respect to Petitioner, a settlement agreement between
`Petitioner and Patent Owner, or a request to keep settlement agreement
`separate under 37 C.F.R. § 42.74(c);
`FURTHER ORDERED that the case caption in IPR2020-00040 shall
`be changed in accordance with the attached example; and
