      “1 US 9,445,919 B2, issued Sept. 20, 2016 (Ex. 1057). 2 At this preliminary stage, Petitioner establishes a reasonable likelihood that Palmatier anticipates or renders obvious the challenged claims (Pet. 22–66), and Patent Owner does not challenge Petitioner’s showings as to Palmatier.” slip op. at 2

    • Novelty / Anticipation (§102) › Priority / effective filing date / continuation supportDecided for petitioner

      “Patent Owner does present some evidence of conception, diligence, and constructive reduction to practice, but Petitioner persuasively disparages that evidence on the preliminary record. For example, Patent Owner relies on April and May 2011 emails exchanged between two or more of the named inventors (Exs. 2027–2031, 2056, 2057, 2059) and a declaration from one of the named inventors, Dr. Nathan Moskowitz (Ex. 2024), to show conception of the claimed subject matter. Prelim. Resp. 8–61. Patent Owner also relies on Dr. Moskowitz’s declaration and emails (Exs. 2045, 2049, 2050) to show reasonably continuous diligence leading up to the filing of a provisional patent application. Id. at 63–66. Petitioner asserts that the documentary evidence does not show conception of the claimed “ridges,” in part, because a key email attachment regarding an embodiment for ridges has not been provided. Pet. Reply 1–4. Petitioner also asserts that Patent Owner’s relies on the declaration testimony from only one named inventor, which is vague and should be the subject of cross-examination. Id. Given these disputes, during trial, the parties are free to develop the record as to the asserted prior conception and diligent reduction to practice of the claimed subject matter, relative to Palmatier’s filing date.” slip op. at 3

    The Director denied institution of the IPR, finding Apple's unexplained inconsistent claim-construction positions before the Board and district court problematic.

      “As I have indicated previously, petitioners should be presenting a single construction and applying that construction consistently. See Infineon Techs. Americas Corp. v. Mosaid Techs. Corp., IPR2025-01456, Paper 27 at 3–4 (Director Mar. 17, 2026). Failure to do so, without adequate explanation, is problematic and raises concerns of strategic litigation behavior spill-over into the PTAB inconsistent with Congress’s intent to provide a quick and cost-effective alternative to district court litigation. Id.; Revvo, Paper 20 at 3–4; see H.R. Rep. No. 112-98 at 48 (2011). Here, Petitioner offers no explanation for its divergent positions.” slip op. at 3

      “that “[a]ll claim terms should be construed according to their ordinary and customary meaning,” and that “no claim terms need be construed to resolve issues of controversy in the present Petition.” Paper 2, 4 (emphasis added). Petitioner also states, as part of its analysis of the challenged claims, that “Petitioner does not concede that the preambles of the Challenged Claims are limiting.” Id. at 9 n.5 (emphasis added). In district court, however, Petitioner tells a different story, arguing there that the preamble is limiting. Ex. 2016, 6, 7, 9, 12. Indeed, Petitioner specifically denotes that “[r]eview of ‘the entirety of the patent’ makes clear that the preamble phrase ‘high speed memory chip module’ contains the core of what the inventors ‘actually invented and intended to encompass by the claims,’ . . . and so the preamble should be limiting.” Id. at 7 (internal citations omitted, emphasis added).” slip op. at 2

    • Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)Other

      “IPR2026-00243 are similarly problematic. In its Petitions, Petitioner identifies “input/output unit” as a means-plus-function limitation and identifies the corresponding structure as input/output unit 106 in the challenged patent. See, e.g., IPR2026-00241, Paper 2, 4. Petitioner also asserts “the applied prior art anticipates or renders obvious the Challenged Claims, regardless of whether ‘input/output unit’ is construed as a §112(f) means-plus-function limitation,” and that “Petitioner is not conceding . . . that the ’017 Patent provides adequate structure for the ‘input/output unit.’” Id. at 5 (emphasis added). In District Court, however, Petitioner once again takes a different position, arguing that the claim term “input/output unit” should be construed as a means-plus-function limitation, identifying the function as “performing input and/or output functions with respect to memory,” and asserting that the challenged patent “[l]acks sufficient structure (indefinite).” IPR2026-00241, Ex. 2016, 12. According to Petitioner, “[t]he specification fails to disclose sufficient corresponding structure for performing input and output operations with respect to memory, much less for performing those operations within any particular voltage range.” Id. at 19. Petitioner fails to adequately explain its different positions here before the Board and those it propounds in district court. See, e.g., IPR2026-00241, Paper 9. Patent Owner well states the issue; that “[t]o the extent § 112(f) governs, then either input/output unit 106 is sufficient corresponding structure (in which case [Petitioner’s] district-court indefiniteness argument fails), or it is not (in which case [Petitioner’s] IPR mapping relies on a structure [Petitioner] itself maintains is inadequate).” IPR2026-00241, Paper 8, 8–9. I agree. Petitioner’s statement that it does not concede the challenged patent provides adequate structure for the “input/output unit” thus only compounds the problem.” slip op. at 3

      “As I have indicated previously, a petitioner should present a single construction and apply that construction consistently. See Infineon Techs. 1 Citations are to papers in IPR2026-00133. The parties filed similar papers in IPR2026-00134 and IPR2026-00135. Americas Corp. v. Mosaid Techs. Corp., IPR2025-01456, Paper 27 at 3–4 (Director Mar. 17, 2026). Failure to do so, without adequate explanation, is problematic. Id.; Revvo, Paper 20 at 3–4. A petitioner may not avoid presenting its own claim construction position in a proceeding before the Office by presenting an analysis based on claim construction positions taken by other parties in a different proceeding. See 37 C.F.R. § 42.104(b)(3) (requiring that the petition must “set forth . . . [h]ow the challenged claim is to be construed”); Trial Practice Guide2 §§ II.B.(3) and (6). Permitting such conduct would allow a petitioner to avoid taking a consistent claim construction position. Such conduct would undermine the purpose of inter partes review proceedings and detract from the Office’s goal of “providing greater predictability and certainty in the patent system.” Revvo, Paper 20 at 4–5. While certain arguments are highlighted above, the determination to exercise discretion to deny institution is based on the complete record and a holistic assessment of all of the evidence in light of the arguments presented.” slip op. at 2
