`INTRODUCTION
`I.
`A. Background and Summary
`Apple Inc. (“Petitioner”) filed a Petition (Paper 1, “Pet.”) requesting
`inter partes review of claims 1–17 of U.S. Patent No. 8,352,730 B2
`(Ex. 1001, “the ’730 patent”). Additionally, Petitioner filed a Motion for
`Joinder Under 35 U.S.C. § 315(c) and 37 C.F.R. §§ 42.22 and 42.122(b) to
`Related Inter Partes Review IPR2024-00775. Paper 3 (“Joinder Mot.”).
`Petitioner also filed a Supplemental Paper and Notice Ranking Petitions.
`Paper 4 (“Ranking Notice”). Patent Owner filed a Preliminary Response.
`Paper 8 (“Prelim. Resp.). With our authorization, Petitioner filed a
`Preliminary Reply. Paper 9 (“Prelim. Reply”). Patent Owner declined to
`file a preliminary sur-reply by our deadline to do so.
`We have authority to determine whether to institute an inter partes
`review. See 35 U.S.C. § 314 (2016); 37 C.F.R. § 42.4(a) (2019). The
`standard for instituting an inter partes review is set forth in 35 U.S.C.
`§ 314(a), which provides that an inter partes review may not be instituted
`“unless . . . there is a reasonable likelihood that the petitioner would prevail
`with respect to at least 1 of the claims challenged in the petition.” For the
`reasons explained below, we decline to institute an inter partes review of the
`’730 patent. We also deny Petitioner’s Joinder Motion.
`
`
`B. Related Matters
`The parties advise us that the ’730 patent is involved in six district
`court cases, including Proxense, LLC v Apple, Inc., Case No. 6:24-cv-00143
`(W.D. Tex.). Pet. 100; Paper 6, 2. The ’730 patent also has been challenged
`at the Board in the following inter partes review petitions: Google, LLC v.

`E. Institution of Inter Partes Review
`Petitioner has filed two petitions challenging the ’730 patent, the
`instant Petition (filed October 16, 2024) and a petition in IPR2024-01333
`(filed August 22, 2024). The instant Petition is accompanied by a motion
`seeking to join Petitioner as a party to IPR2024-00775. Joinder Mot. 1. The
`Board has already granted the petition in IPR2024-01333 (“’1333 petition”)
`and joined Petitioner as a party to IPR2024-00232. Ranking Notice 1.
`According to PTAB guidance, “[b]ased on the Board’s experience,
`one petition should be sufficient to challenge the claims of a patent in most
`situations.” Consolidated Trial Practice Guide (“TPG”) 59 (Nov. 2019),
`available at https://go.usa.gov/xpvPF. “Two or more petitions filed against
`the same patent at or about the same time (e.g., before the first preliminary
`response by the patent owner),” the situation we have here, “may place a
`substantial and unnecessary burden on the Board and the patent owner and
`could raise fairness, timing, and efficiency concerns.” Id. Thus, “multiple
`petitions by a petitioner are not necessary in the vast majority of cases.” Id.
`That said,
`the Board recognizes that there may be circumstances in which
`more than one petition may be necessary, including, for
`example, when the patent owner has asserted a large number of
`claims in litigation or when there is a dispute about priority date
`requiring arguments under multiple prior art references. In such
`cases two petitions by a petitioner may be needed, although this
`should be rare.
`Id. In such situations, a petitioner is invited to identify, either in its petition
`or a separate ranking paper (Petitioner filed the Ranking Notice):
`
`4
`
`
`
`IPR2024-01486
`Patent 8,352,730 B2
`
`
`(1) a ranking of the petitions in the order in which it wishes the
`Board to consider the merits, if the Board uses its discretion to
`institute any of the petitions, and (2) a succinct explanation of
`the differences between the petitions, why the issues addressed
`by the differences are material, and why the Board should
`exercise its discretion to institute additional petitions if it
`identifies one petition that satisfies petitioner’s burden under
`35 U.S.C. § 314(a).
`Id. at 59–60 (emphasis added). In a separate paper or in the preliminary
`response (Patent Owner provided a Preliminary Response), the patent owner
`is permitted to
`respond to the petitioner and explain why the Board should not
`exercise its discretion to institute more than one petition (if it
`institutes at all). Among other issues, the patent owner should
`explain whether the differences identified by the petitioner are
`directed to an issue that is not material or not in dispute. If
`stating that issues are not material or in dispute, the patent
`owner should clearly proffer any necessary stipulations. For
`example, the patent owner may seek to avoid additional
`petitions by proffering a stipulation that certain claim
`limitations are not disputed or that certain references qualify as
`prior art.
`Id. at 60–61.
`In its Ranking Notice, Petitioner requests that we institute both the
`’1333 petition and the instant Petition, but ranks the ’1333 petition first and
`the instant Petition second. Ranking Notice 1. Thus, if we decide that
`Petitioner has not provided sufficient justification for instituting two
`petitions, we should deny the instant Petition, as we have already instituted
`the ’1333 petition.
`Petitioner argues that we should institute both petitions because
`“Petitioner’s petitions in the 1333 IPR and the 1486 IPR are . . . materially
`different.” Ranking Notice 2. Petitioner shows that the ’1333 petition
`
`5
`
`
`
`IPR2024-01486
`Patent 8,352,730 B2
`
`challenges a subset of the claims of the ’730 patent based on the prior art
`references Ludtke and Kon, while the instant Petition challenges all 17
`claims of the ’730 patent based on the prior art references Burger and
`Robinson. Id. at 2–3. According to Petitioner, these are “significantly
`different invalidity grounds.” Id. at 3. However, Petitioner does not explain
`why challenging the same patent with different invalidity grounds, without
`more, justifies instituting both petitions.
`Petitioner also argues that “the 1486 IPR challenges an additional
`claim not challenged in the 1333 IPR—i.e., claim 7 of the ’730 patent.”
`Id. at 3. Claim 7 is a dependent claim. Ex. 1001, 9:59–67. Petitioner does
`not explain in its Ranking Notice why the additional claim challenged in the
`Petition presents a material difference.
`One exemplary justification for multiple petitions is “when the patent
`owner has asserted a large number of claims in litigation.” TPG 59.
`Petitioner does not argue that it was impractical to challenge in one petition
`all claims asserted in litigation. Patent Owner argues the contrary, stating
`that, “though this Petition challenges dependent claim 7 of the 730 Patent,
`which was not challenged in the 1333 IPR, Patent Owner has not asserted
`claim 7 against [Petitioner] in the current co-pending litigation. . . . Thus,
`the only difference between the petitions is a challenge to a dependent claim
`not at issue.” Prelim. Resp. 2.
`Petitioner argues that Patent Owner did not clearly proffer a
`stipulation not to assert claim 7. Prelim. Reply 2. According to Petitioner,
`Patent Owner’s statement that claim 7 is not at issue is “incorrect and
`misleading” because Patent Owner “would not agree to sign a covenant not
`to sue [Petitioner] on claim 7,” and that “Proxense’s litigation tactics result
`
`6
`
`
`
`IPR2024-01486
`Patent 8,352,730 B2
`
`in claim 7 remaining ‘at issue’ and the current co-pending litigation is of no
`consequence.” Id. In support of this argument, Petitioner cites to the
`Preliminary Response, at 2. Id. The Preliminary Response says nothing
`about whether Patent Owner would agree to sign a covenant not to sue on
`claim 7. Prelim. Resp. 2. And Petitioner does not meaningfully allege a
`concern that claim 7 will be asserted. Petitioner does not show that the
`addition of claim 7 makes the difference between the two petitions material.
`Moreover, Petitioner could have ranked the instant Petition, which
`challenges the additional claim, higher, but chose not to for reasons that are
`not presented here.2 Petitioner does not persuade us that the additional
`challenge to claim 7 in the Petition is material.
`As to the other exemplary justification stated in the TPG, “when there
`is a dispute about priority date requiring arguments under multiple prior art
`references,” TPG 59, Patent Owner represents that “there is no dispute about
`the priority date regarding either combination of references,” and that
`“Patent Owner has not denied that either combination [of] references
`constitutes prior art,” Prelim. Resp. 2. Petitioner does not argue that there is
`any dispute as to priority date justifying two petitions.
`Petitioner argues that it could not have raised both sets of challenges
`in the instant Petition because issues in the instant Petition could not be
`joined to the ’232 IPR that the ’1333 petition sought to join. Prelim. Reply
`1–2 (citing Facebook, Inc. v. Windy City Innovations, LLC, 973 F.3d 1321,
`
`2 It is notable that Petitioner does not provide reasons why, should we
`institute on the instant Petition, the 1333 petition still would be justified. In
`other words, Petition has not explained why the challenges presented in the
`1333 petition are materially different from those presented in the instant
`Petition.

`
`1336–37 (Fed. Cir. 2020)). We appreciate that Petitioner did not draft either
`petition in the first instance, and instead chose to copy petitions to facilitate
`joinder. While it might be the case that Petitioner could not have combined
`the two petitions and still sought joinder, Petitioner still does not provide a
`reason why it should be permitted two petitions. Alleging that the
`challenges presented in the two petitions are materially different, by itself,
`does not show “why the issues addressed by the differences are material.”
`TPG 60.
`We have considered the reasons for two petitions presented in the
`Ranking Notice, but find insufficient argument or evidence to show that this
`is the “rare” case in which two petitions might be needed by Petitioner.
`Accordingly, consistent with the guidance in the TPG, we exercise our
`discretion to deny the Petition under 35 U.S.C. § 314(a).
`
`
`II. PETITIONER’S JOINDER MOTION
`As noted above, Petitioner requests joinder of this proceeding with
`IPR2024-00775. Joinder Mot. 1. As the moving party, Petitioner bears the
`burden of proving that it is entitled to joinder. See 37 C.F.R. § 42.20(c).
`Joinder in inter partes review proceedings is subject to the provisions
`of 35 U.S.C. § 315(c):
`(c) JOINDER.—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 parties review under section 314.
`

`
`
`
`IPR2024-01486
`Patent 8,352,730 B2
`
`“To join a party to an instituted [inter partes review (IPR)], the plain
`language of § 315(c) requires two different decisions.” Facebook, Inc. v.
`Windy City Innovations, LLC, 973 F.3d 1321, 1332 (Fed. Cir. 2020). “First,
`the statute requires that the Director (or the Board acting through a
`delegation of authority) . . . determine whether the joinder applicant’s
`petition for IPR ‘warrants’ institution under § 314.” Id. “Second, to effect
`joinder, § 315(c) requires the Director to exercise h[er] discretion to decide
`whether to ‘join as a party’ the joinder applicant.” Id. “The statute makes
`clear that the joinder decision is made after a determination that a petition
`warrants institution, thereby affecting the manner in which an IPR will
`proceed.” Id. (citing Thyrv, Inc. v. Click-to-Call Techs., LP, 140 S.Ct. 1367,
`1377 (2020)).
`As we explain above, Petitioner has not shown that we should institute
`a second Petition by Petitioner challenging the ’730 patent. Instead, we
`determine that the Petition does not warrant institution. Accordingly, the
`Joinder Motion fails at the first step, whether the Petition warrants
`institution, and we need not evaluate further the second step, whether to join
`Petitioner as a party to IPR2024-00775.
`Petitioner’s Joinder Motion is denied.
`
`
`III. CONCLUSION
`We exercise our discretion to deny the Petition because Petitioner has
`not shown that we should institute a second petition by Petitioner
`challenging the ’730 patent.
`Because the Petition does not warrant institution, we deny Petitioner’s
`Joinder Motion.
