“Id. The Director neither addressed the merits of Petitioner’s challenges nor found that our prior consideration of those merits was faulty. Accordingly, we understand that we need not reconsider our conclusion that Petitioner had demonstrated a reasonable likelihood of proving that claims 1, 2, 7–9, 11, 12, and 20–24 were unpatentable or that the merits of patentability set forth in the Petition warranted institution of inter partes review.” slip op. at 5

“The question before us, therefore, is whether the Petitioner’s proffered explanation that it has proposed a different claim interpretation before the Board because the District Court may decline to adopt the narrower claim interpretations it advocates there is sufficient. We find that Petitioner’s explanation is sufficient because it follows the Director’s exemplary logic. Whether a district court has already or might in the future decline to adopt constructions that a petitioner proposes in related district court litigation merely reflects the timing of when a dispute over claim interpretation will be resolved. The Director and Patent Owner both recognize that, to resolve the dispute over claim interpretation that exists here, a decision-maker must determine “a single claim construction that best captures the true meaning of the patent claim.” Remand 4; PO Remand Br. 3. Based on the record presented by the parties to date in this proceeding, no dispute exists that the disputed claim terms mean what Patent Owner says they mean in the Litigation. Accordingly, we find that, at this stage of the proceeding, it is undisputed that Patent Owner’s interpretations of the claim terms represent the “single claim construction that best captures the true meaning of the patent claim.”8 Under that claim interpretation, we” slip op. at 8

“Patent Owner is likely correct that the ITC would not have been inclined to grant a stay if one had been requested at the time the Institution Decision issued. Moreover, the ITC conducted a full evidentiary hearing a month after the Institution Decision issued, and the target date for the ITC’s final determination is several months before the projected statutory deadline for the Board’s final written decision. PO Remand Br. 7. Accordingly, we determine that Fintiv factor 1 weighs in favor of discretionary denial. See also Klein Tools, Inc. v. Milwaukee Electric Tool Corp., IPR2024-01400, Paper 22 at 2 (PTAB June 9, 2025) (Acting Director Stewart determining that Fintiv factor 1 weighs in favor of discretionary denial when the ITC investigation is unlikely to be stayed, the ITC already conducted a full evidentiary hearing, and the ITC final determination is expected to issue six months before the statutory deadline for the Board’s final written decision).” slip op. at 19

“stay or evidence exists that one may be granted if a proceeding is instituted.” Fintiv, Paper 11 at 6. A stay of litigation pending resolution of an inter partes review allays concerns about inefficiency and duplication of efforts, and strongly weighs against exercising our authority to deny institution. Fintiv, Paper 11 at 6. The Guidance Memo states that “the Board will apply the Fintiv factors when there is a parallel proceedings at the International Trade Commission.” Guidance Memo 2. Patent Owner asserts that a stay of the ITC Investigation had not been requested at the time of the Institution Decision,7 and argues that “the ITC does not stay investigations pending IPR.” PO Supp. Br. 4. Patent Owner also notes that the Institution Decision issued “just days before the ITC evidentiary hearing.” Id. Accordingly, Patent Owner argues that this factor favors denial. Id. Patent Owner is likely correct that the ITC would not have been inclined to grant a stay if one had been requested at the time the Institution Decision issued.

“As used herein, the term “hearing aid profile” refers to a collection of acoustic configuration settings for hearing aid 102, which are used by a processor 110 to shape electrical signals related to sounds to compensate for the user's hearing loss. Ex. 1001, 3:11–15. Petitioner states that Patent Owner defined this term in the ’538 patent as “a collection of acoustic configuration settings for hearing aid 102, which are used by processor 110 to shape electrical signals related to sounds to compensate for the user’s hearing loss.” Pet. 15. According to Petitioner, this construction is consistent with the plain and ordinary meaning of the term, relying upon the testimony of its witness Dr. Les Atlas. Pet. 15 (citing Ex. 1003 ¶ 38).10 Patent Owner does not dispute Petitioner’s proposed construction. Resp. 10–11. 10 Dr. Les Atlas is the Petitioner’s witness in this matter. We find him qualified to testify as to the subject matter of this proceeding, by virtue of his education and experience. See Ex. 1003 ¶ 4, and Appendix A thereto. We are cognizant of Patent Owner’s suggestion that we give his testimony “little, if any, weight” because of the similarity of the testimony with Petitioner’s arguments and discrepancies between it and his deposition testimony. Resp. 31–34. We give Dr. Atlas’ testimony appropriate contextual weight herein based upon the content of the testimony itself, and any contrary testimony in Exhibit 2005. We decline to assign generally no weight to his testimony, however. supports, and is consistent with, Petitioner’s proposal. Ex. 1001, 3:12–16. Accordingly, we determine that the broadest reasonable construction, in light of the specification of the ’538 patent, of the term “hearing aid profile” is a “collection of acoustic configuration settings for hearing aid, which are used by a processor to shape electrical signals related to sounds to compensate for a user’s hearing loss.”” slip op. at 8

“We find the testimony of Dr. Atlas on the key point of obviousness of pre-mixing processing to be less persuasive than that of Mr. Brown. We also find Dr. Atlas’ testimony falls short of adequately explaining how the combination of Cohen and Martin teaches a nexus (i.e., the “based on both the first [shaped] output signal and the second [shaped] output signal” (emphasis added) (hereinafter, “based on both limitation”) limitation recited in claim 1) between the claim 1 requirements of: (1) a condition precedent of shaping both a first output signal and a second output signal; and (2) a subsequent result of using both the first shaped output signal and the second shaped output signal if the hearing aid is in a third mode. Dr. Atlas assumes that one of ordinary skill in the art would process separately each signal and then mix them. Ex. 1003 ¶ 66. We find Dr. Atlas’ assumption is flawed. Specifically, in making this assumption, Dr. Atlas does not address adequately how the combination of Cohen and Martin opines “it would have been obvious to a person of ordinary skill in the art” (emphasis added), his later sentences appears to base his opinion principally on the reason one of ordinary skill in the art could do it. Id. In particular, he testifies: Because Cohen’s hearing aid applies different hearing aid profiles to different input sources, it would have been obvious to a person of ordinary skill in the relevant art to add the functionality of the combination mode as taught by Martin to Cohen’s hearing aid such that the speaker would produce an audible sound based on the output signals of the processor. Combining two signals such that both signals are sent to a speaker to an audible combination of sounds, that is where each signal is sufficiently perceived, was well within the technical ability of a person of ordinary skill in the art. To accomplish this would require that each one of the two signals is passed through an appropriate hearing aid profile. For example, it would have been obvious to a person of ordinary skill in the art that a different hearing aid profiles could be used for an audio coil inputs and that of a neighboring conversation and environmental sounds through a microphone. Namely, it is commonly known that the different frequency sensitivity of an audio telecoil versus a microphone can be beneficially compensated for. (Rodriquez, Ex. 1011, Abstract)” slip op. at 24
