Claims 13, 14, and 17–27 were not shown unpatentable because Tennant did not establish that Wikey or Davies inherently disclosed the claimed microbubbles and nanobubbles.
RulingsRemand decision- RemandOther
“The Federal Circuit vacated and remanded our anticipation determinations as to claims 13, 14, and 17–27. Tennant, 11.1 The Federal Circuit further stated: “Because we vacate and remand to the Board to consider Tennant’s anticipation argument, we do not reach Tennant’s obviousness arguments (which depends on its contention that either Wikey or Davies produce nanobubbles).” Id. at 11. On September 19, 2024, we authorized the parties to file supplemental briefing, stating also that the “parties are not authorized to present new factual assertions, provide additional exhibits, or raise new arguments beyond those directed to the issues raised in the remand.” Ex. 3001. Pursuant to this authorization, Petitioner filed an Opening Brief on Remand (Paper 61; “Pet. Br. Rem.”) in support of its contentions. Patent Owner filed a Lead Brief on Remand (Paper 62; “PO Br. Rem.”) in support of its contentions. Petitioner filed a Reply Brief on Remand (Paper 66; “Pet. Reply Br. Rem.”). Patent Owner filed a Responsive Brief on Remand (Paper 65; “PO Resp. Br. Rem.”).” slip op. at 3
- Novelty / Anticipation (§102) › Anticipation standard (single reference, every element) › Inherent disclosureInherency not foundNot shown unpatentable
“Accordingly, and in line with our previous determination that “Wikey appears to disclose each limitation of claim 13 except ‘microbubbles and nanobubbles having a bubble diameter of less than 50 microns’” (Final Dec. 20), we determine that Petitioner has not demonstrated that Wikey inherently discloses microbubbles or nanobubbles. Accordingly, Petitioner has not demonstrated that Wikey discloses every limitation of claim 13.” slip op. at 56

Claims 1–7, 9, 10, 13, 14, 18–21, and 25–30 were not shown unpatentable because the asserted combinations did not establish the claimed speaker-independent speech recognition device.

“predefined voice patterns,” but disagree as to whether it should require a device that recognizes spoken words “without adapting to individual speakers.” PO Resp. 21 (“The proper construction of ‘speaker-independent speech recognition device’ is consistent with the construction issued by the Western District of Texas, though it does not include all of that court’s construction, and requires at least ‘speech recognition device that recognizes spoken words without using predefined voice patterns.’”); Reply 2 (“For purposes of this IPR, Apple submits the Court’s construction should be applied.”). The dispute as to whether the term should preclude adapting to individual speakers does not impact any issue in this proceeding, and Petitioner has agreed to Patent Owner’s construction in this proceeding, so long as we do not resolve the dispute over adapting to individual speakers. Tr. 12:24–13:4 (“JUDGE McKONE: So you’d be happy if we essentially adopted Parus’s construction with a footnote or some kind of note that we’re not resolving the issue of adapting to individual speakers? MS. BAILEY: That would be fine for purposes of this IPR, Your Honor.”). We adopt the parties’ agreed approach. For purposes of this proceeding, “speaker-independent speech recognition device” means “speech recognition device that recognizes spoken words without using predefined voice patterns.” This is consistent with the ’431 patent’s statement (relied on by both parties) that “[t]he voice browsing system recognizes naturally spoken voice commands and is speaker-independent; it does not have to be trained to recognize the voice patterns of each individual user. Such speech recognition systems use phonemes to recognize spoken words and not predefined voice patterns.” Ex. 1001, 4:38–43; see also PO Resp. 21–22 (citing Ex. 1001, 4:34–43);” slip op. at 10
- Skill levelSkill level petitioner adoptedDecided for petitioner
“Level of Skill in the Art Petitioner, relying on the testimony of Dr. Terveen, contends that a person of ordinary skill in the art “would have had a Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or equivalent degree, with at least two years of experience in interactive voice response systems, automated information retrieval systems, or related technologies, such as web-based information retrieval systems.” Pet. 6 (citing Ex. 1003 ¶ 28). Patent Owner does not contest Petitioner’s proposal or offer an alternative. Also, neither party argues that the outcome of this case would differ based on our adoption of any particular definition of one of ordinary skill in the art. Petitioner’s proposal is consistent with the technology described in the Specification and the cited prior art. On the complete record, we adopt Petitioner’s proposed level of skill.” slip op. at 12
- ExcludeMotion to exclude, deniedDenied
“A motion to exclude should be directed to the admissibility of evidence. See 37 C.F.R. § 42.64; TPG 79 (“A motion to exclude must explain why the evidence is not admissible (e.g., relevance or hearsay) but may not be used to challenge the sufficiency of the evidence to prove a particular fact.”). According to the Trial Practice Guide, a motion to exclude is not a vehicle to “address arguments or evidence that a party believes exceeds the proper scope of reply or sur-reply.” TPG 79. Rather, “[i]f a party believes that a brief filed by the opposing party raises new issues, is accompanied by belatedly presented evidence, or otherwise exceeds the” slip op. at 41
- Strike new argumentNew argument disregardedDecided for patent owner
“corresponding to an unclaimed second step not part of speech recognition would be an impermissible new argument presented for the first time in the Reply. As explained in the Board’s Trial Practice Guide, Petitioner’s change in direction exceeds the proper scope of a reply: Generally, a reply or sur-reply may only respond to arguments raised in the preceding brief. 37 C.F.R. § 42.23, except as noted above. “Respond,” in the context of 37 C.F.R. § 42.23(b), does not mean proceed in a new direction with a new approach as compared to the positions taken in a prior filing. While replies and sur-replies can help crystalize issues for decision, a reply or sur-reply that raises a new issue or belatedly presents evidence may not be considered. The Board is not required to attempt to sort proper from improper portions of the reply or sur-reply. Patent Trial and Appeal Board Consolidated Trial Practice Guide 74 (November 2019) (“TPG”).7 If Petitioner is arguing that Ladd’s description of voice patterns and speech patterns is not describing speaker-independent speech recognition, then Petitioner’s Reply does not simply respond to the Patent Owner Response or attempt to crystalize the issues in dispute. Rather, the Petition expressly relied on certain disclosure in Ladd to show the functionality claimed in limitation 1[c], while the Reply attempts to re-cast that same disclosure as describing functionality separate from that of limitation 1[c]. This would be a new theory.” slip op. at 29
