“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

“11 Petitioner defines the level of ordinary skill in the art as someone with a Bachelor’s degree in electrical engineering and at least two years of experience in the field of audio engineering. Pet. 14 (citing Ex. 1003 ¶ 25). Patent Owner does not challenge Petitioner’s definition. Resp. passim. The references in the record support a finding that this is the appropriate level. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art itself can reflect the appropriate level of skill in the art). 12 The record contains no allegations or evidence of secondary considerations.” slip op. at 10

“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

“We recognize that it may be necessary “to look to interrelated teachings of multiple patents . . . in order to determine whether there was an apparent reason to combine the known elements in the fashion claimed.” KSR Int’l, 550 U.S. at 418. Petitioner in these proceedings, however, directs us to no persuasive reason why an ordinary artisan would have turned to the heat-retaining battery module of Hallaj when working to implement a plurality of Sato’s cells in a pack to replace the capacitors in Fohr. Pet. 36–38 (nowhere addressing that critical point); Reply 13 (devoting four sentences to rebuttal of Patent Owner’s persuasive evidence that one would not have combined the disclosures of Hallaj, Fohr, and Sato in the manner claimed); see Ex. 1033, 15 (Examiner’s observation, in confirming the patentability of the challenged claims during reexamination, that Sato contains “no information as to how Sato’s cells would be implemented in a pack”). We view Petitioner’s unexplained leap from the single battery cell of Sato to the heat-retaining battery module of Hallaj as a classic example of impermissible hindsight reconstruction driven not by any teaching in the prior art, but by the claim requirement of a “plurality” of cells implemented in a battery pack. Pet. 36–38; Reply 13. Patent Owner, by contrast, comes forward with persuasive evidence, which we credit, showing that one of ordinary skill in the art would not have been led to arrange a plurality of Sato’s cells in the heat-retaining battery module of Hallaj because such a modified battery pack would have been unsuitable for use as a replacement for the capacitors in Fohr. Specifically, we credit the testimony of Dr. Blomgren, who cogently explains why a person of ordinary skill in the art would not have been led to the proposed modification. Ex. 2147 ¶¶ 79–85.” slip op. at 17

“We are not persuaded by Dr. Riley’s testimony that Fohr effectively teaches that both lithium-based battery cells and capacitors can achieve the 20 Amp Limitation, on a theory that “it’s actually the tool that draws the power” and “the right lithium cell” would be “a drop in replacement for this application.” Ex. 2169, 121:12–16 (Dr. Riley’s deposition testimony); Resp. 17. Dr. Riley readily admitted an unfamiliarity with capacitors, and identified no suitable “drop in” ready lithium cells available at the time of the invention. Ex. 2169, 121:11–122:4 (“[I]f I had a cell that could do similar things, I’d certainly swap it in there.”). On that point, we find more credible Dr. Blomgren’s testimony that “there is no guarantee that a given pack of battery cells can provide the current that a tool tries to draw.” Resp. 17 (citing Ex. 2147 ¶ 60).” slip op. at 13

“B. Level of Ordinary Skill in the Art We hold that the prior art references asserted in the Petition are representative of the level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (absence of specific findings on “level of skill in the art does not give rise to reversible error ‘where the prior art itself reflects an appropriate level and a need for testimony is not shown’” (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985)). To the extent that a more specific definition is required, we hold that an ordinary artisan would include one holding a Bachelor’s Degree in Electrical Engineering with two or three years of experience in battery design. That definition comports with the very similar definitions advanced by the parties. In that regard, Petitioner asserts that an ordinary artisan would encompass a person holding a Bachelor’s Degree in Electrical Engineering with three years of experience in battery design. Pet. 8; Ex. 1007 ¶ 9. Patent Owner similarly asserts that an ordinary artisan would include a person holding a Bachelor’s Degree in Electrical Engineering with two years of battery design experience. Resp. 8; Ex. 2105 ¶ 24.” slip op. at 9

“In our Decisions to Institute, we construed the 20 Amp Limitation to require that “the battery cells, when configured together in a battery pack, are capable of producing reasonably close to 20 amps of discharge current or greater over the course of delivering their entire rated capacity.” Dec. 5. Neither party disputes that construction, which we adopt for the purposes of this Final Written Decision. To the extent that any other claim term requires express construction, we discuss the construction in our analysis below. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (only claim terms in controversy need be construed, and then only to the extent necessary to resolve the controversy).
