“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.

“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.”).

“A petition for inter partes review must identify “all real parties in interest.” 35 U.S.C. § 312(a)(2). The Office Patent Trial Practice Guide provides guidance regarding factors to consider in determining whether a party is a real party in interest. 77 Fed. Reg. 48,756, 48,759–60 (Aug. 14, 2012). Considerations may include whether a non-party “funds and directs and controls” an IPR petition or proceeding. Id. at 48,760. Additional relevant factors include: the non-party’s relationship with the petitioner; the non-party’s relationship to the petition itself, including the nature or degree of involvement in the filing; and the nature of the entity filing the petition. Id. Generally, a party does not become a “real party-in-interest” merely through association with another party in an unrelated endeavor. Id. A party also is not considered a real party in interest in an inter partes review solely because it is a joint defendant with a petitioner in a patent infringement suit or is part of a joint defense group with a petitioner in the suit. Id. Whether a party who is not a named participant in a given proceeding is a “real party-in-interest” to that proceeding “is a highly fact-dependent question.” Id. at 48,759. There is no “bright line test.” Id. Courts invoke the term “real party-in-interest” to describe relationships and considerations sufficient to justify applying conventional principles of estoppel and preclusion. Id. Here, even assuming this contention is timely, Patent Owner has failed to provide any evidence, besides the mere fact that the other parties are co-defendants in a lawsuit or alleged infringers, to support the contention that Petitioner has failed to name all of the real parties in interest.

Petitioner’s declarant, however, has put forward a detailed discussion of various references dated before April 20064 (the date Patent Owner now alleges is the priority date) related to subject matter of the ’990 patent. See Ex. 1005 ¶¶ 20–74, 94–99. We have reviewed that discussion and the references cited in those paragraphs. We have found it accurately reflects the teachings of the references. Moreover, we agree with Petitioner’s declarant that the references are analogous to the claimed invention, and, as such, represent the level of skill in the relevant art at the time of the invention. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

“We agree with Petitioner and find, based on the Patent Owner’s own arguments, that these terms improperly broaden the scope of the claims. As Patent Owner explains, the added language is broad enough to include the removed items, and is intended to reflect the entire genus of “monitoring equipment” and “communications devices” that “are capable of communication and capable of receiving signals.” Mot. to Amend 4, 5. Thus, the claim has been broadened to not only include the listed species that have been removed, but anything falling within the claimed genus. Accordingly, we find that this amendment impermissibly broadens the claim. As for the second change in the claim language, we find that Patent Owner has failed to show why removal of the entire passage “wherein, the communication device receives a signal via any of one or more products listed in any of the plurality of product grouping categories,” would not impermissibly broaden the scope of claim 154. The deletion of this limitation necessarily broadens the claim in that limitation’s aspect. See In re Clement, 131 F.3d 1464, 1468 (Fed. Cir. 1997) (“For example, a reissue claim that deletes a limitation or element from the patent claims is broader in that limitation’s aspect.”). Given that Patent Owner has entirely deleted this limitation and Patent Owner bears the burden of showing entitlement to the amendment, it was incumbent on Patent Owner to explain why removing this entire passage from claim 154 would not broaden the scope of the claim. See In re Bennett, 766 F.2d 524, 526 (Fed.
