“Petitioner fails to show that the full scope of claim 9 of Seet is described in the Seet provisional. Seet expressly defines the claim term “media,” stating that, as it is “used herein,” “media” includes audio, video, software, and pictures. Ex. 1006 ¶ 50 (“Media content may include one . . . of audio . . ., video . . ., software . . ., and pictures”). Such a statement provides a clear definition of the term “media” that includes video, software, and pictures, in addition to audio. In addition to the express definition, Seet elsewhere indicates that its media includes video and other non-audio signals and databases.

Accordingly, the use of media in claim 9 for its claimed “media content database” and “media stream[s]” also includes both audio and non-audio media. The disclosure of the Seet provisional, however, is more limited and defines the term media exclusively as audio. Ex. 1019, 4 (“Media will be defined as any streaming audio source in any form, be it radio, television, cable, satellite, internet stream, or the like.”).

“art would not have modified Kurita in view of Lemoff because Lemoff positions the signal emitters near the fiber to emulate WDM without the need for an external optical multiplexer or a similar device and discourages using optical wavelength multiplexers for short distances because the complexity of the design is often cost prohibitive (PO Resp. 47–48), Lemoff does not appear to limit the usefulness of the fiber connector to any particular optical signal transmission distance. Petitioner relies upon Lemoff for a suggestion to combine Lemoff’s fiber connector configuration teachings with Kurita’s multiplexer teachings to enable fibers to be plugged Fig. 2) (Pet 29, 31; Reply 17–18). Regarding Patent Owner’s argument that one of ordinary skill in the art would not have combined Lemoff’s receptacle and ferrule with discrete components in Kurita because the fiber would need to be manually fixed and aligned with or without a ferrule and, therefore, would serve no purpose (PO Resp. 48), Lemoff’s fiber connector appears to fix and align the fiber adequately for wavelength division multiplexing without manual fixation or alignment being required (Ex. 1006, 5:65–6:2, Fig. 2; Reply 18). The challenged claims do not require any greater degree of fixing and alignment than that provided by Lemoff’s fiber connector. Regarding Patent Owner argument that Lemoff’s device is not physically combinable with Kurita’s WDM multiplexer due to Lemoff’s device’s small size (PO Resp. 47–48; Reply 17–18), “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference.... Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art” (In re Keller, 642 F.2d 413, 425 (CCPA 1981)).

“stopped single optical fiber because fixing it in place does not passively align it with the optical components (PO Resp. at 35–37) is not persuasive because fixing Kurita’s fiber (40) in place in accord with Lemoff’s teaching regarding the ferrule (255) inserted until being stopped by the receptacle (260) (Ex. 1006, 5:50–6:15, Fig. 2) would align Kurita’s optical array (20), and lens (30)) (Ex. 1004 Fig. 3) passively in the same manner that Lemoff’s ferrule (255), after being inserted until stopped by the receptacle (260), passively aligns the optical fiber (250) with the optical components (optical imaging element 220 and light emitters within emission apertures 120) (Ex. 1006, 5:50–6:15, Fig. 2; Reply 15–16). Regarding Patent Owner’s argument that the light from each of Kurita’s lasers (11) depicted in Figure 3 cannot pass through a separate focusing lens (30) pie shaped sector because the lasers (11) and collimating lenses (21) are arranged linearly rather than being arranged about a circular axis (PO Resp. at 37–42), we do not agree. Claim 1 requires “focusing means having n separate radial sectors on its surface, and each of said n collimated beams passes through a separate one of said n sectors of said focusing means” (Ex. 1001, 5:34–37), claim 2 requires “four lasers and four collimating lenses are each formed in a two-dimensional, two by two array [centered on the focal axis of lens 30], wherein said focusing means is a single focusing lens, and wherein each radial sector is a pie-shaped quadrant” (id. at 5:41–44), and claim 7 requires “focusing means having four separate quadrants on its surface, and each of said four collimated beams passes through a separate one of said quadrants of said focusing means” (id. at 6:35–38). Kurita meets those claim requirements. Kurita’s two by two array (10A) of lasers (11), collimating lens (21) array (20), and focusing lens (30) are shown in Kurita’s Figure 3 (cropped) as follows: The image is a portion of Kurita’s Figure 3 showing Kurita’s laser array, collimating lens array, and focusing lens (30). Relative to a point at the center of the laser array (10A) or the collimating lens array (20), each laser (11) and each collimating lens (21) is in a separate quadrant that can be a quadrant of a circle (pie-shape) on lens 30 (Reply 12– 13, Ex. 1003 ¶¶ 85–91).” slip op. at 23

“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.

“Petitioner contends that a person of ordinary skill in the art “would have had a Master’s degree in material science, chemical engineering, chemistry, or similar field with four years of experience designing testing, and building secondary lithium batteries.” Pet. 11 (citing Ex. 1002 ¶ 51). 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. (citing Ex. 1002 ¶¶ 50–51). Patent Owner “does not dispute Petitioner’s level of ordinary skill.” PO Resp. 17.

“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. Patent Owner contends that this is merely an unclaimed embodiment, but the relevant disclosure states that the charging device for the “present invention” may be any type of device “with the proviso that said charging device controls the charge cut-off voltage.” Id. at 9:50–53.” slip op. at 12

Petitioner argues that because the battery of Uemura is charged “to” a maximum voltage of 4.3 V, Uemura discloses the claimed charge cut-off voltage under either Petitioner’s or Patent Owner’s construction of the term. Pet. Reply 11–12 (citing Ex. 1009 ¶ 81; Ex. 1044 ¶¶ 56–59). This argument is not persuasive because Mr. Juzkow unambiguously testified that charging in Uemura stopped when the applied voltage reached 4.3 V, and Uemura discloses that the battery was charged “at” a voltage ranging from 4.3 V to 2.0 V, not “to” such a voltage. Ex. 1009 ¶ 81; Ex. 2008, 113:2–13; Ex. 2006 ¶ 119 n.64; Sur-reply 9. In view of the foregoing, we determine that Petitioner has not demonstrated by a preponderance of the evidence that Uemura anticipates independent claims 1 and 5 of the ’641 patent.” slip op. at 21

“Under the circumstances presented here, we find that discretionary denial is not warranted for the Petition in this case due to the parallel petition in IPR2024-00890. Given the large number of claims asserted by Patent Owner against Petitioner in the district court litigation, we do not consider two petitions asserting two single-reference grounds against forty claims including five independent claims to be excessive. The CTPG provides that assertion of a large number of claims in litigation is one circumstance under which more than one petition may be necessary. CTPG at 59. Furthermore, the two petitions challenge different claims of the ’031 patent. Claim length and subject matter complexity also justify the additional briefing presented by two petitions for which Patent Owner has been afforded the same amount” slip op. at 4

“Since Petitioner does not propose any alternative construction for “drift profile” or construction of any other term in this proceeding, there is no dispute over claim terms that we need to decide to resolve. Accordingly, we will apply the ordinary and customary meaning of the claim terms in our analysis of the challenge grounds without express construction. See Nidec, supra. Id. (citing Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017)). We note in passing, however, that Patent Owner’s stated definition of “drift profile” in its Preliminary Response seems to comport both with Petitioner’s proposal in the district court litigation4 as well as how the ’031 patent’s specification uses the terms “drift” and “profile” in the context of “sensitivity.” See Ex. 1001, 21:36–48 (discussing “drift”), 210:39–60 (discussing “profile”).” slip op. at 15
