“Although Petitioner asserts that the ’463 patent “does not limit the form of a data feed,” Petitioner does not explain what the ordinary and customary meaning of “data feed” was at the time of the claimed invention or otherwise propose an express construction of “data feed.” Pet. 6–7, 23. Nor does Petitioner point to any prosecution history that bears on the meaning of “data feed.” Id.; see 37 C.F.R. § 42.100. Accordingly, Petitioner does not provide sufficient evidence showing that Kraft’s or Wong’s disclosure of search results in response to a user-entered search query teaches a “data feed,” as recited in each challenged claim of the ’463 patent.

“I agree with Patent Owner. Neither Kraft nor Wong uses the term “data feed” or characterizes its listing of Web pages (Kraft) or nodes (Wong) provided in response to a user-provided query as a “data feed.” See Ex. 1005, 5:8–12, 6:52–59, 16:52–59, 18:31–54, 18:61–19:23; Ex. 1007 ¶¶ 22, 28, 35. Petitioner points to a disclosure in the ’463 patent of a user requesting a personal information aggregator (PIA) to “receive a data feed.” Pet. 23 (citing Ex. 1001, 12:52–64). But Petitioner does not sufficiently explain how this disclosure provides support for broadly construing “browsing a data feed” to encompass a user entering criteria for a search (and not specifically requesting a “data feed”) and receiving a listing of Web pages or nodes in response. See Pet. 23, 58–59; Ex. 1003 ¶¶ 102, 201–202; Ex. 1005, 6:57–59 (describing users searching a data store for models that match “user-specified criteria”), 18:41–54 (describing a user submitting a query); Ex. 1007 ¶ 28 (describing “searching and selecting from keyword identifiers or other search terms”). Petitioner’s reliance on a separate disclosure in the ’463 patent of the PIA “searching . . . the network for information about the situation or event” also is not persuasive, because the ’463 patent does not describe that embodiment as involving a data feed or browsing a data feed.

“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.

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.
