“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.

“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
- Strike new argumentOther
“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.

“combination deficient. Petitioner argues that Park’s walls are “likely to collapse under the suction force,” based not on Park, but on Baughan, which states that “discs” in Baughan are used to prevent the “flexible sleeve” of Baughan from collapsing. Pet. 89. (citing Ex. 1007, 3:46–48). Petitioner reasons that because Park uses silicone, a flexible material, Park’s walls must also collapse like Baughan. Id. (citing Ex. 1006 ¶¶ 32, 34). Petitioner, however, directs us to no disclosure in Park to suggest that the material used in Park or the arrangement of Park would collapse in the same manner as Baughan. Indeed, if Park’s mouthpiece collapses as Petitioner speculates, it would appear likely to render Park inoperable. See Ex. 2030 ¶ 205. Additionally, Petitioner recognizes that in Park “the sidewalls and the insertion part 111 would help resist this collapsing force,” and states that in Park it “is unclear whether the mouth prop 100 includes a spine or other rigid structure running through the middle of the mouth prop 100.” Pet. 89– 90. Thus, whether Park is susceptible to collapse is, at best, unknown. See Prelim. Resp. 48 (asserting that a person of ordinary skill would have known “that silicone can have varying degrees of hardness, tensile strength, and elasticity such that Park’s mouthpiece would not necessarily collapse under suction”) (citing Ex. 2030 ¶¶ 189–90; Ex. 2036; Ex. 2037). Even assuming, as Petitioner asserts, that “additional anti-collapsing structure would assist at the weakest areas of the tongue retractor” in Park, Petitioner offers insufficient reasoning for why a person of ordinary skill would have turned to Baughan and modified the structure taught by Baughan to instead conform to what is recited in claim 1. Petitioner’s suggestion that “common sense” would have led a person of ordinary skill in the art to modify the structures of Baughan to solve a problem with collapse in Park that Park does not suggest was a problem is likewise unpersuasive and insufficient. Pet. 93 (further asserting that “it was well known in the art how to make projections on a flat surface”). Petitioner’s reliance on Johnson as generically teaching that protrusions can be on flat surfaces does not supply a reason why a person of ordinary skill in the art would have made the proposed modifications outside of improper hindsight. See also Prelim. Resp. 58, 59 (arguing that the projections in Johnson are on a semicircular surface, not on a flat surface as Petitioner asserts) (citing Ex. 1008 Figs. 4, 5). Based on the evidence and arguments presented, we determine that Petitioner fails to show sufficiently for purposes of instituting inter partes review that the asserted combination of Park, Baughan, and Johnson, or in further combination with Zheng, teaches “protrusions protruding from an interior surface” of one wall of the mouthpiece “towards” an opposing wall of the mouthpiece, as required by claim 1, or that a person of ordinary skill in the art would have had reason to combine the asserted references in the manner alleged by Petitioner.” slip op. at 28
