    Institution was denied for claims 1–12 because the petition did not show that the cited search results taught the claimed “data feed.”

    • PTAB / AIA Trials › Institution threshold (reasonable likelihood / more likely than not)Institution denied meritsInstitution denied

      “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. As such, Petitioner does not demonstrate a reasonable likelihood it would prevail in showing at least one claim is unpatentable, as 35 U.S.C. § 314(a) requires.” slip op. at 4

      “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. See Pet. 23 (citing Ex. 1001, 20:46–51) (emphasis omitted); Ex. 1001, 20:46–51.” slip op. at 3

      “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

      “Petitioner misstates the Decision’s reasoning. As is clear from the previous discussion, we determined that Petitioner’s articulated reasons for combining EP’536 with CN’180 lacked a rational underpinning, not because “EP’536 does not relate to ‘air bags,’” but because the means by which EP’536’s device inflates differs fundamentally from that of CN’180’s device.

      “EP’536 with CN’180 lacked a rational underpinning because EP’536’s inflation mechanism differs fundamentally from CN’180’s inflation mechanism. Dec. 17–18. As we stated, whereas CN’180’s fall-protection belt uses an airbag that requires an external source of pressurized air to inflate, EP’536’s garment does not need an external inflation device because “the gas generating agent 18 in each envelope automatically generates gas and inflates the envelopes in response to rising temperatures.” Id. at 18 (citing Ex. 1004 ¶ 15; Ex. 1005 ¶¶ 5, 19). This difference reflects the fundamentally different purposes of the two devices: CN’180’s device is designed to provide “fall protection” to, e.g., “elderly people,” (Ex. 1005 ¶ 1, 3), whereas EP’536’s device provides “adaptive thermal insulation” for, e.g., garments worn by fire fighters. Ex. 1004 ¶¶ 1–3, 250. Because of the different means by which EP’536’s and CN’180’s devices inflate and the different purposes for doing so, we were not persuaded that one of ordinary skill in the art would have combined the references as Petitioner proposed. Dec. 18. We further noted that the modification would not have improved the reusability of EP’536’s device “by having only one mechanism to recharge,” because EP’536’s “gas generating agent does not need any ‘mechanism to recharge.’” Dec. 18. Instead, we noted EP’536’s teaching that its gas generating agent “automatically recombines or condenses in response to a temperature decrease to return the envelopes, and therefore the garment, to its original thickness, at which point the gas generating agent is ready for subsequent reactivation.” Id. (citing Ex. 1004 ¶¶ 139–141). Finally, we determined that replacing EP’536’s envelopes with CN’180’s airbag “would have made EP’536’s invention unsuitable for its intended purpose: providing a protective garment with ‘adaptive thermal insulation.’” Dec. 19. We stated that “Petitioner does not suggest, and we have found nothing in the record to establish, that CN’180’s airbag would provide this feature.” Id. at 20.” slip op. at 3

      “rationales for combining EP’536 and CN’180. Reh’g Req. 6–7. First, Petitioner asserts that we “improperly rejected Petitioner’s ‘simple substitution’ evidence in view of [the Board’s] incorrect conclusion that EP’536 does not disclose an ‘external source of inflation [EP’536’s dosing aids].’” Id. at 6 (citing Dec. 18–19). This argument is unpersuasive at least because, as we discussed above, EP’536’s dosing aids do not constitute an external source of inflation. Petitioner further argues that we incorrectly evaluated its “obvious to try” rationale because, contrary to our analysis, Petitioner did in fact identify a problem to be solved by its “finite number of solutions”: “simplify[ing] the design and reduc[ing] the number of required inflation mechanisms.” Id. at 6–7. The Petition’s entire “obvious to try” discussion is as follows: [A] POSITA would have found it obvious to try a one-piece airbag 10 with strip-shaped inflation units 12 in the EP’536- CN’180 airbag system because it would have been a selection from a finite number of identified predictable solutions (i.e., using one chamber with connected individual inflation units 12 versus multiple individual envelopes 20). 5 Petitioner also argues that dosing aids are “needed in order to make the disclosed device reusable.” Reh’g Req. 5–6. This is incorrect, as EP’536 conveys that the reusability of the device is a result of the gas generating agent condensing or recombining when temperatures fall. Ex. 1004 ¶¶ 139– 141. Even if it were true, however, it is unclear how it would support Petitioner’s argument. Pet. 16. As is evident, Petitioner did not identify a design need, market pressure, or other problem that would have been addressed by its identified “solutions,” and therefore we were not persuaded by this rationale. Dec. 19. Petitioner’s attempt to cure this deficiency in its Rehearing Request is tardy. We cannot misapprehend or overlook an assertion that Petitioner fails to make in the Petition. It is also insufficient. Petitioner does not provide any evidence of a known design need or market pressure to “simplify [EP’536’s] design” or reduce the number of “required inflation mechanism” it uses.” slip op. at 7

      “[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
