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

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.

“that RF carriers, CDMA codes, TDMA time slots or other information defining and describing the way data is being transmitted do not include underlying data that is transmitted. In isolation, the phrase “not including underlying data that is being transmitted” could be subject to different interpretations. It could simply mean that data being transmitted by itself is not a radio resource, but the RF carrier transmitting the data could be a radio resource. Patent Owner makes clear, however, that this interpretation is not the intent of its construction by arguing that, under its construction, Hettstedt’s RF carriers are not radio resources because they have data modulated on them. Prelim. Resp. 24–27. Similarly, Patent Owner argues that Wu’s carriers are not radio resources because they have payload data encapsulated in them. Id. at 34; see also id. at 35.

In addition, an ordinarily skilled artisan would have been motivated to implement Wellington’s teaching to improve the adaptability of Hettstedt’s system. Id.

“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.

“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.

Neither party disputes that construction, which we adopt for the purposes of this Final Written Decision.
