      “As I recently explained, it is appropriate to deny institution when a Petitioner’s conduct demonstrates that the dispute “is less about a litigation alternative and more about inconsistent positions to gain an upper hand in the overall litigation.” Terumo BCT Inc. v. Haemonetics Corp., IPR2025- 01374, Paper 20 (Director May 12, 2026). Here, as in Terumo, Petitioner advanced indefiniteness contentions in the co-pending district court litigation at its first opportunity to do so after institution was granted. See Paper 15, 1–2 (listing seven allegedly indefinite terms and phrases impacting all challenged claims). Although Petitioner contends that its unpatentability arguments for the “and/or” and “one or more” claim limitations fit within the Tesla framework, i.e., that the prior art discloses the claimed features regardless of how those limitations are construed, Petitioner’s indefiniteness contentions are broader than those two limitations. See, e.g., Paper 15, 1–2; IPR2025-01383, Paper 9 at 8–10. Thus, it is appropriate to deny institution of these IPRs for the same reasons as articulated in Terumo.” slip op. at 3

      “Petitioner’s conduct, which ensued following institution, demonstrates that this dispute is less about a litigation alternative, as Congress intended, and more about inconsistent positions to gain an upper hand in the overall litigation. See, e.g., H.R. Rep. No. 112-98, at 48 (2011) (explaining that IPRs were intended to provide “quick and cost effective alternatives to litigation”). Such conduct has negative consequences: It multiplies litigation expense, reduces patent value, discourages innovation, diminishes the integrity of the patent system, and depletes the Office’s resources. Discretion is afforded to the USPTO Director to ensure fairness, efficiency, and predictability in patent disputes in a focused inter partes context—as Congress envisioned—as distinct from the broad adversarial context in district court litigation. The Office’s review under Article I is ultimately regulatory; proceedings under Article III are adjudicatory. I would not have instituted these IPRs in the first instance had Petitioner engaged in this strategic litigation-style behavior before institution. Accordingly, the appropriate course of action is to grant Director Review, vacate the Notice granting institution of these IPRs, and deny institution.” slip op. at 4

      “Petitioner’s assertion that the term “controller” is not in controversy in these IPRs and so it was not required to construe the term in the Petitions is an inadequate justification for the different positions. As I have stated repeatedly, a petitioner should present a single construction and apply that construction consistently before the Board and the district court. See, e.g., Infineon Techs. Am. Corp. v. Mosaid Techs. Corp., IPR2025-01456, Paper 27 at 3–4 (Director Mar. 17, 2026) (“[A] petitioner should pick one [construction], and one consistent with its asserted District Court position.”). Failure to do so detracts from the Office’s goal of “providing greater predictability and certainty in the patent system.” Revvo, Paper 20 at 4–5. I also disagree with Petitioner’s assertion that these IPRs do not implicate Rule 42.104(b)(3). Rule 42.104(b)(3) requires a petition to “[p]rovide a statement of the precise relief requested for each claim challenged,” and to identify how each challenged claim is to be construed. The rule continues to state that “[w]here the claim to be construed contains a means-plus-function or step-plus-function limitation as permitted under 35 U.S.C. 112(f), the construction of the claim must identify the specific portions of the specification that describe the structure, material, or acts corresponding to each claimed function.” 37 C.F.R. § 42.104(b)(3). Petitioner’s position in the district court that the term “controller” is a means-plus-function limitation undercuts its position that Rule 42.104(b)(3) does not apply here. Further, Petitioner’s citation to Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) as support for its position is inapposite, as the holding in that case addresses when the Board is required to construe a claim term, not when a party is required to follow Board rules.

The Petition offers no explanation, stating only that “no claim terms require a formal construction for purposes of addressing the grounds in this Petition.” See Pet. 4.

      “[W]hen a petitioner advances different positions before the Board and a district court, that petitioner is required to explain why those different positions are warranted.” Tesla Inc., v. Intellectual Ventures II, LLC, IPR2025-00340, Paper 18 at 3 (Director Nov. 5, 2025) (informative) (citing Revvo Techs., Inc. v. Cerebrum Sensor Techs., Inc., IPR2025-00632, Paper 20 at 3–5 (Director Nov. 3, 2025) (precedential)). Petitioner has not done so. Rather, Petitioner has stipulated that it will continue to pursue different constructions and abandon the inconsistent construction in district court if the IPR is instituted. This is not in keeping with our precedent, and I decline to modify it to permit this approach. Additionally, Petitioner’s claim construction stipulation is distinguishable from its stipulation that “it will not pursue in the parallel litigation the grounds it raised or could have reasonably raised in the petition, and that it will not pursue any ground that relies on Ohliger or the Veepio system.” DD Opp. 1–2. The latter stipulation increases efficiency by reducing duplication between the district court and the Board. It also minimizes the potential for inconsistent outcomes in the two proceedings. Petitioner’s stipulation not to continue to advance different claim construction positions lacks similar benefits. At best, it replaces one argument in district court for another argument at the Board. Accordingly, the Petition is denied under 35 U.S.C. § 314(a). slip op. at 2
