`
`STATEMENT OF THE PRECISE RELIEF REQUESTED
`Apple Inc. (“Petitioner”) respectfully submits this Motion for Joinder,
`
`together with a Petition for Inter Partes Review of U.S. Patent No. 9,679,289 (“’289
`
`Patent”) (IPR2025-00075, “the 0075 Petition”) filed contemporaneously herewith.
`
`Pursuant to 35 U.S.C. § 315(c) and 37 C.F.R. § 42.122(b), Petitioner requests
`
`institution of an inter partes review and joinder with the inter partes review in
`
`Google LLC v. Proxense, LLC, IPR2024-00783 (“the Google IPR”). The 0075
`
`Petition is also narrowly tailored to the same claims, prior art, and grounds for
`
`unpatentability that are the subject of the Google IPR. In addition, Petitioner is
`
`willing to streamline discovery and briefing. Petitioner understands that Google does
`
`not oppose Petitioner’s request for joinder.
`
`Petitioner submits that joinder is appropriate because it will not unduly burden
`
`or prejudice the parties to the Google IPR while efficiently resolving the question of
`
`the ’289 Patent’s validity in a single proceeding.
`
`II.
`
`STATEMENT OF MATERIAL FACTS
`On April 19, 2024, Google LLC filed a petition for inter partes review
`1.
`
`(IPR2024-00783) requesting cancellation of claims 1-20 of the ʼ289 Patent.
`
`2.
`
`On August 20, 2024, Patent Owner filed its preliminary response,
`
`setting a deadline for the Board to issue an institution decision of November 20,
`
`2024. 35 U.S.C.§ 315(b); IPR2024-00783, Paper 5.
`
`
`
`1
`
`
`
`3.
`
`Contemporaneously with this Motion, Petitioner filed its Petition for
`
`Inter Partes Review requesting cancellation of claims 1-20 of the ʼ289 Patent, which
`
`is substantively identical to the Google IPR.
`
`III. STATEMENT OF THE PRECISE RELIEF REQUESTED
`Legal Standard
`A.
`The Board has the authority under 35 U.S.C. § 315(c) to join a properly filed
`
`inter partes review petition to an instituted inter partes review proceeding. See 35
`
`U.S.C. § 315(c). A motion for joinder must be filed within one month of the Board
`
`instituting an original inter partes review. 37 C.F.R. § 42.122(b). In deciding
`
`whether to exercise its discretion and permit joinder, the Board considers factors,
`
`including: (1) the reasons why joinder is appropriate; (2) whether the new petition
`
`presents any new grounds of unpatentability; (3) what impact, if any, joinder would
`
`have on the trial schedule for the existing review; and (4) how briefing and discovery
`
`may be simplified. Kyocera Corporation v. Softview LLC, IPR2013-00004, Paper
`
`15 at 4 (April 24, 2013).
`
`Petitioner’s Motion for Joinder is Timely
`B.
`This Motion for Joinder is timely because it is filed before any institution
`
`decision has been made in the Google IPR. 37 C.F.R. § 42.122(b).
`
`Each Factor Weighs in Favor of Joinder
`C.
`Each of the four factors considered by the Board weighs in favor of joinder
`
`here. Specifically, the 0075 Petition does not present any new grounds of
`
`
`
`2
`
`
`
`unpatentability; rather it is substantively identical to the Google IPR Petition.
`
`Further, joinder will have minimal, if any, impact on any forthcoming trial schedule,
`
`as all issues are substantively identical and Petitioner will accept an “understudy”
`
`role. See Sony Corp. et al. v. Memory Integrity, LLC, IPR2015-01353, Decision
`
`Instituting IPR Review, Motion for Joinder, Paper 11 at 6; (granting IPR where
`
`petitioners requested an “understudy” role); see also IPR2015-01353, Motion for
`
`Joinder, Paper 4 at 5-7. Lastly, the briefing and discovery will be simplified by
`
`resolving all issues in a single proceeding.
`
`Joinder is Appropriate
`1.
`Joinder with the Google IPR is appropriate because the 0075 Petition involves
`
`the same patent, challenges the same claims, relies on the same expert declaration,
`
`and is based on the same grounds and combinations of prior art submitted in the
`
`Google IPR Petition. Id. The 0075 Petition is substantively identical to the Google
`
`IPR Petition, containing only minor differences related to only other issues
`
`associated with a different party filing the petition. The 0075 Petition presents no
`
`changes to the facts, citations, evidence, or arguments related to patentability
`
`presented in the Google IPR Petition. Because these proceedings are substantively
`
`identical, good cause exists for joining this proceeding with the Google IPR so that
`
`the Board can efficiently resolve all grounds in both the 0075 Petition and Google
`
`IPR Petition in a single proceeding. Id.
`
`
`
`3
`
`
`
`Petitioner Proposes No New Grounds of Unpatentability
`2.
`The 0075 Petition presents the same grounds of unpatentability as the Google
`
`IPR Petition.
`
`3.
`
`Joinder Will Not Unduly Burden or Negatively Impact
`Any Forthcoming Google IPR Trial Schedule
`Because the 0075 Petition is substantively identical to the Google IPR
`
`Petition, with the same grounds challenging the same claims as in the original
`
`Google IPR Petition, there are no new substantive issues for Patent Owner to
`
`address. Due to the same issues being presented in the 0075 Petition and the Google
`
`IPR Petition, Patent Owner will not be required to present any additional responses
`
`or arguments. See IPR2015-01353, Decision Instituting IPR, Motion for Joinder,
`
`Paper 11 at 6 (granting IPR and motion for joinder where “joinder should not
`
`necessitate any additional briefing or discovery from Patent Owner beyond that
`
`already required in [the original IPR].”); see also IPR2015-01353, Motion for
`
`Joinder, Paper 4 at 5-7.
`
`The Patent Owner Response will also not be negatively impacted because the
`
`issues presented in the Google IPR Petition are identical to the issues presented in
`
`the 0075 Petition. Patent Owner will not be required to provide any additional
`
`analysis or arguments beyond what it will already provide in responding to the
`
`Google IPR Petition. Also, because the 0075 Petition relies on the same expert and
`
`
`
`4
`
`
`
`an identical declaration, only a single deposition is needed for the proposed joined
`
`proceeding.
`
`Joinder of this proceeding with the Google IPR does not unduly burden or
`
`negatively impact any forthcoming trial schedule in any meaningful way. Further,
`
`even if a small adjustment of the trial schedule was necessary, this is already provided
`
`for in the rules and is a routine undertaking by parties in IPR proceedings. See 37
`
`C.F.R. § 42.100(c). Thus, a slight adjustment in the trial schedule, should one be
`
`needed, is not enough of a reason to deny joining the present 0075 Petition with the
`
`Google IPR.
`
`Procedures to Simplify Briefing and Discovery
`4.
`The Google IPR Petition and 0075 Petition present substantively identical
`
`grounds of unpatentability, including the same art combinations against the same
`
`claims. Additionally, Petitioner explicitly agrees to take an “understudy” role, as
`
`described by the Board:
`
`“(a) all filings by [Petitioner] in the joined proceeding be consolidated
`with [the filings of the petitioner in the Google IPR], unless a filing
`solely concerns issues that do not involve [the petitioner in the Google
`IPR]; (b) [Petitioner] shall not be permitted to raise any new grounds
`not already instituted by the Board in the [Google] IPR, or introduce
`any argument or discovery not already introduced by [the petitioner in
`the Google IPR]; (c) [Petitioner] shall be bound by any agreement
`between [Patent Owner] and [the petitioner in the Google IPR]
`
`
`
`5
`
`
`
`concerning discovery and/or depositions; and (d) [Petitioner] at
`deposition shall not receive any direct, cross-examination or redirect
`time beyond that permitted for [the petitioner in the Google IPR] alone
`under either 37 C.F.R. § 42.53 or any agreement between [Patent
`Owner] and [the petitioner in the Google IPR].”
`
`Noven Pharmaceuticals, Inc. et al. v. Novartis AG et al., IPR2014-00550, Paper 38
`
`at 5 (Apr. 10, 2015) (emphasis in original). Petitioner will assume the primary role
`
`only if Google ceases to participate in the Google IPR.
`
`By Petitioner accepting an “understudy” role, Patent Owner and Petitioner can
`
`comply with any forthcoming trial schedule and avoid any duplicative efforts by the
`
`Board or the Patent Owner. These steps will minimize any potential complications
`
`or delay that potentially may result by joinder. See IPR2015-01353, Decision
`
`Instituting IPR, Paper 11 at 6-7 (granting IPR and motion for joinder because
`
`“joinder would increase efficiency by eliminating duplicative filings and discovery,
`
`and would reduce costs and burdens on the parties as well as the Board” where
`
`petitioners agreed to an “understudy” role.); see also IPR2015-01353, Motion for
`
`Joinder, Paper 4 at 6-7.
`
`Accordingly, joinder should be permitted. See IPR2015-01353, Decision
`
`Instituting IPR Review, Motion for Joinder, Paper 11 at 5-6 (granting institution of
`
`IPR and motion for joinder where petitioners relied “on the same prior art, same
`
`arguments, and same evidence, including the same expert and a substantively
`
`
`
`6
`
`
`
`identical declaration.”); see also IPR2015-01353, Motion for Joinder, Paper 4 at 4-
`
`5.
`
`IV. GENERAL PLASTIC IS INAPPLICABLE
`In General Plastic Co., Ltd. v. Canon Kabushiki Kaisha, the Board
`
`“recognize[d] the potential for abuse of the review process by repeated attacks on
`
`patents.” IPR2016-01357, slip op. 16–17 (PTAB Sept. 6, 2017) (Paper 19)
`
`(precedential). In General Plastic, the Board set forth a series of factors that may be
`
`analyzed for follow-on petitions to help conserve the finite resources of the Board.
`
`Petitioner respectfully submits that application of the General Plastic analysis is
`
`inapplicable here. In the current motion, Petitioner merely seeks to join Google’s
`
`petition and does not present any new grounds. As such, Petitioner respectfully
`
`submits that General Plastic does not apply in this circumstance because Petitioner
`
`would be taking an understudy role and the Board’s finite resources would not be
`
`impacted. Moreover, a joinder petition in these circumstances is not the type of serial
`
`petition to which General Plastic applies, especially as Petitioner has not previously
`
`filed an IPR against the ’289 Patent. The PTAB has previously stated that a joinder
`
`petition “effectively neutralizes” a General Plastic analysis. See Apple Inc. v. Uniloc
`
`2017 LLC, IPR2018-00580, Paper 13 at 10 (PTAB Aug. 21, 2018) (instituting a
`
`joinder petition where joinder petitioner previously filed a non-instituted IPR, stating
`
`joinder petitioner’s joinder motion agreeing to a passive understudy role “effectively
`
`
`
`7
`
`
`
`neutraliz[es] the General Plastic factors”); see also Celltrion, Inc. v. Genentech,
`
`Inc., IPR2018-01019, Paper 11 at 10 (PTAB Oct. 30, 2018) (instituting a joinder
`
`petition where joinder petition previously filed a non-instituted IPR, stating the
`
`joinder motion “effectively obviates any concerns of serial harassment and
`
`unnecessary expenditure of resources”). Furthermore, the Patent Owner did not
`
`argue that the General Plastic factors warranted exercising the Board’s discretion to
`
`deny the challenges from the Google IPR that Petitioner now seeks to join. IPR2024-
`
`00783, Paper 5.
`
`In the event the Board does analyze the General Plastic factors, those factors
`
`heavily weigh in favor of instituting the present IPR. General Plastic at 16.
`
`Regarding the first factor, Petitioner has not previously filed a petition against
`
`the ’289 Patent. This factor weighs in favor of institution.
`
`The second factor is whether at the time of filing the first petition the petitioner
`
`knew or should have known of the prior art asserted in the second petition. This
`
`factor is neutral, if not inapplicable, in the General Plastic analysis. Here, Google’s
`
`petition and 0075 Petition share the same prior art because the 0075 Petition is a
`
`“copycat” of Google’s petition. Because Petitioner is merely seeking to join in an
`
`understudy role, the factor is neutral, at best, in determining whether to institute.
`
`The third factor is whether at the time of filing of the second petition the
`
`petitioner already received the patent owner’s preliminary response to the first
`
`
`
`8
`
`
`
`petition or received the Board’s decision on whether to institute review in the first
`
`petition. Because this is a Motion for Joinder requesting an understudy role,
`
`Petitioner is submitting a substantively identical petition and has not added to, or
`
`changed, any of the substantive arguments from the Google petition. Moreover,
`
`because the present Petition is submitted as a joinder and Petitioner will serve an
`
`understudy role, the Petition is not an attempt to harass the Patent Owner or
`
`otherwise engage in serial, tactical filings. Thus, this factor weighs against denial of
`
`joinder/institution.
`
`The fourth factor is the length of time elapsed between the time the petitioner
`
`learned of the prior art asserted in the second petition and filing of the second
`
`petition, and the fifth factor is whether the petitioner provides adequate explanation
`
`for the time elapsed between the filings of multiple petitions directed to the same
`
`claims of the same patent. In the context of a joinder motion where Petitioner will
`
`be taking an understudy role, these factors are inapplicable.
`
`The sixth factor is the finite resources of the Board. Allowing Petitioner’s
`
`joinder motion where it will serve in an understudy role will not impact the Board’s
`
`resources beyond those resources the Board dedicates to the instant joinder motion.
`
`The seventh factor is the requirement under 35 U.S.C. § 316(a)(11) to issue a
`
`final determination not later than 1 year after the date on which the Director notices
`
`
`
`9
`
`
`
`institution of review. As noted above, joining Petitioner should not impact any
`
`forthcoming schedule. Accordingly, this factor weighs in favor of institution.
`
`An eighth factor identified by the Board in Shenzhen is the extent to which
`
`the petitioner and any prior petitioner(s) were similarly situated defendants or
`
`otherwise realized a similar-in-time hazard regarding the challenged patent.
`
`Shenzhen Silver Star Intelligent Tech. Co., Ltd. v. iRobot Corp., IPR2018-00898,
`
`Paper 9 at 7, 13-14 (PTAB Oct. 1, 2018) (noting “the purpose of proposed Factor 8
`
`is to discourage tactical filing of petitions over time by parties that faced the same
`
`threat at the same time” such that earlier petitions are filed as “test case(s)” to gain
`
`“tactical advantage”). Petitioner is not similarly situated as the petitioner for the
`
`Google IPR. The petitioner for the Google IPR was sued on the ’289 Patent in a case
`
`filed on May 2, 2023. The Petitioner here was sued on the ’289 Patent on October
`
`31, 2024. Furthermore, because the 0075 Petition does not introduce any new
`
`grounds of unpatentability and will effectively merge into a single proceeding with
`
`Google’s IPR, no tactical advantage is gained here.
`
`Thus, none of the General Plastic factors weighs against institution and
`
`joinder in this situation.
`
`
`
`
`
`
`
`
`
`10
`
`
`
`V. CONCLUSION
`Based on the factors discussed above, Petitioner respectfully requests that the
`
`Board grant the 0075 Petition for Inter Partes Review of U.S. Patent No. 9,679,289
`
`and then grant joinder with the Google IPR2024-00783 proceeding.
