Petitioner further contends that a person of ordinary skill in the art would have been aware of “(1) positive electrode materials, (2) negative electrode materials, (3) separators, (4) electrolytes, (5) charge-discharge parameters, and (6) protection circuits, as well as ‘battery failure modes’ such as plating and the formation of dendrites.” Id.

      “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged. Ex. 2013; Ex. 2006 ¶ 91. Thus, the applied voltage may be, but is not necessarily, the charge cut-off voltage. In view of the foregoing, we construe “charge cut-off voltage” in claims 1 and 5 as “the maximum value to which the battery is configured to be charged.” PO Resp. 18; Ex. 2008, 217:6–11; Pet. Reply 5. Contrary to Patent Owner’s arguments, however, we do not understand the phrase “configured to be charged” to necessarily represent a single voltage for the battery that is determined based on the structure and chemistry of the battery. Pet. Reply 4–5. Rather, the charge cut-off voltage is a selected potential, or voltage, of the battery or cell at the end of charging that is controlled by a circuit or device, such as a charger or control circuit within the battery. Ex. 1001, 9:50–55; Ex. 1048, 2, 7–8; Ex. 1008, 3:9–13. And, for the reasons discussed herein, the charge cut-off voltage may be, but is not necessarily, the same as the applied voltage during charging. PO Resp. 20.” slip op. at 15

      “constructions. First, we agree with Petitioner that the ’641 patent indicates that the charge cut-off voltage selected for a particular battery need not be a fixed property of the battery or something that is set by the design and chemistry of the battery. Consistent with this conclusion, the ’641 patent discloses that a “charging device controls the charge cut-off voltage of the single lithium-ion cell within a range from 4.3 V to 5.8 V.” Ex. 1001, 9:50– 55. This strongly suggests that the charge cut-off voltage is controlled by the charger and is not necessarily an inherent property of the battery.

As discussed in Section II.D.2 below, we determine based on the record at this stage of the proceeding that Petitioner demonstrates sufficiently for purposes of institution that Sun discloses or suggests “discrete carbon nanotubes.” Therefore, we do not explicitly construe any claim terms in this Decision.

See generally Prelim. Resp. Based on the present record, Patent Owner’s statements during prosecution support Petitioner’s argument tthat a graded dopant concentration is enough to teach aiding carrier movement in a particular direction.

Id. At this stage of the proceeding, the evidence of record supports Petitioner’s position sufficiently to meet the reasonable likelihood threshold for institution. We decline to make further determinations, on this preliminary record, regarding the dispute surrounding this limitation, because the trial in the 00001IPR is the better proceeding in which to do so. Specifically, as compared to the preliminary phase of this case, the instituted trial in the 10 The examined claims of the ’195 patent generally recited “a unidirectional drift field drawing all minority carriers from said surface layer to said substrate.” Ex. 1016, 286.

      “IPR. Compare id., with IPR2024-00019, Paper 46 at 1–4, 6–22 (Patent Owner’s response in the Cirrus IPR) (public version). We decline to resolve the material issue of fact surrounding this limitation on this preliminary record, because the trial in the Cirrus IPR is the better proceeding in which to do so. Specifically, as compared to the preliminary phase of this case, the instituted trial in the Cirrus IPR affords the parties a better opportunity to fully and fairly brief, argue, and develop evidence in support of their positions, and, in particular, to address Cirrus Logic’s alleged admission that the existence of a gradient alone is insufficient to disclose the “aid carrier movement” limitations of independent claims 1 and 21.

      “Regarding the “first static unidirectional electric drift field to aid the movement of minority carriers” limitation, Petitioner relies on the parent file history and cited references, arguing that “Payne’s downward-sloping graded-dopant concentration aids the movement of minority carriers from the surface layer to the substrate to the same extent to which Applicant relied on the prior art and admitted to the Patent Office that such carrier movement would occur under the same scenario.” Pet. 23. Petitioner also asserts that the direction in which carriers are forced with the concentration profile disclosed in Payne is downward, toward the substrate and away from the surface. Pet. 23–28 (quoting and citing Ex. 1046, 237–238, 253–254, 289– 290; citing Ex. 1003 ¶¶ 95–106; Ex. 1005, 5:7–17, 5:44–55; Ex. 1009, 2:11– 16, 2:67–3:18, Fig. 2; Ex. 1010, 2:27–32, 5:14–22; Ex. 1013, 431; Ex. 1030, 24).

      “5. “Aid the Movement of Minority Carriers” Patent Owner argues that the Petition fails to show that the applied prior art references disclose the claim limitations “requiring ‘aid the movement of minority carriers,’” as twice recited in claim 1. Prelim. Resp. 8. Patent Owner summarizes this dispute as follows: The challenged patent discloses and claims a semiconductor device with (among other things) a “drift layer having a graded concentration of dopants . . . [and] further having a first static unidirectional electric drift field to aid the movement of minority carriers.”[] The Petition should not be instituted, because (among other deficiencies) it fails to show that the prior art discloses the “aid the movement of minority carriers” claim limitation. Rather than pointing to anything in the prior art that would teach this claim limitation, the Petition assumes that any “graded concentration of dopants” would necessarily “aid the movement of minority carriers.” The Petition contains no analysis explaining why the “graded concentration of dopants” in the prior art meet the “aid the movement of minority carriers” limitation, apart from the fact that they are “graded concentration of dopants.” In other words, Petitioner reads the “aid the movement of minority carriers” limitation out of the claims completely.

      “On the present record, we agree with Petitioner that the two petitions filed to challenge the claims of the ’222 patent will not substantially burden the Board or the parties. The petitions in IPR2024-00673 and IPR2024- 00674 challenge different claims, and those claims appear on the present record to have different claim scope, as Petitioner argues. Paper 3, 3–4 (arguing that claim 44, challenged in IPR2024-00674, recites “a ‘surface layer,’ a ‘single drift layer,’ and ‘at least one well region disposed in the single drift layer,’ which are not” recited in the claims challenged in IPR2024-00673); Ex. 1001, 4:39–8:39. In addition, there is little overlap between the prior art asserted in the two petitions, and what overlap there is—the use of Kawagoe in both petitions—is used in different prior-art combinations in each petition. Compare IPR2024-00673, Paper 4, 5 (asserting Kawagoe alone and in combination with Gupta or Silverbrook), with IPR2024-00674, Paper 4, 5 (asserting Kawagoe in combination with Sakai).
