      “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.

      “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. 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

      “Determining whether claims are anticipated involves a two-step analysis. The first step involves construction of the claims of the patent at issue. Claim construction is a question of law reviewed de novo.” In re Aoyama, 656 F.3d 1293, 1296 (Fed.Cir.2011). “The second step [of an anticipation analysis] involves comparing the claims to the prior art. Anticipation is a question of fact reviewed for substantial evidence.” In re Aoyama, 656 F.3d at 1296. “A prior art reference anticipates a patent claim under 35 U.S.C. § 102(b) if it discloses every claim limitation.” In re Montgomery, 677 F.3d 1375, 1379 (Fed. Cir. 2012). A reference may anticipate inherently if a claim limitation that is not expressly disclosed “is necessarily present, or inherent, in the single anticipating reference.” Verizon Servs. Corp. v.

      “The motivation-to-combine analysis is a flexible one. “[A]ny need or problem known in the field of endeavor at the time of invention and addressed by the patent can provide a reason for combining the elements in the manner claimed,” [but the] “analysis ‘need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.’” Intel Corp. v.

      “validation” as used herein with respect to production lots refers to determining that a particular sample tests negative using the detection assay. Where a modular composite sample tests negative, all single-unit production lot samples comprising the composite sample are validated along with the respective single-unit production lots, which are thus cleared for release. Where a modular composite sample tests positive, individual single unit production lots may nonetheless yet be validated if particular respective single-unit production lot samples test negative. Ex.1002, 7:15–24 (emphasis added). The above text expressly equates “validation” to a determination that “a particular sample tests negative.” The initial definitional sentence makes no mention of “cleared for release” as necessary for “validation.” The subsequent sentence refers to “cleared for release” in the more limited situation where a particular composite sample “tests negative all single-unit production lot samples,” and, even then, the “cleared for release” language indicates a separate step that may happen after the samples are “validated.” slip op. at 21

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

      “On the current record, we are not persuaded that Petitioner has insufficiently articulated a motivation to combine or modify the asserted references. With respect to Ground 1, for example, Petitioner contends that one of ordinary skill in the art would have been motivated to modify ICMSF based on Gombas under the teaching-suggestion-motivation test so portions of the enriched, retained samples are further tested after a positive test of a composite sample by the same protocol, with a reasonable expectation of success for efficient validation. See § XII-A-1-h supra; Dickson ¶¶ 417-19. Pet. 53–54. Petitioner further argues that ordinarily skilled artisan would have sought to improve[] ICMSF with the similar methods of Gombas to yield efficient validation, which is a predictable result. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007). In this combination, a POSA would have simply substituted steps of ICMSF, as described above, with those of Gombas so portions of the enrichment cultures are retained and are further tested after a positive test of a composite sample by the same protocol for predictably efficient validation. MPEP § 2143(I)(B); Dickson ¶ 420. Id. at 53. As such, the Petition provides specific reasons to combine ICMSF and Gombas that are consistent with the flexible test recited in KSR, including the benefit of efficient validation of the test and that the combination is a simple substitution of steps. As KSR notes, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 US at 417.

      “parties on the present record, we are persuaded Petitioner sufficiently shows the combination of Bosnyak-392 and Son teaches or suggests all of the limitations of claim 1, and sufficiently explains how a person of ordinary skill in the art would have used Bosnyak-392’s teaching of using exfoliated, open-ended carbon nanotube fibers having two different aspect ratios in a composition with improved electrical and mechanical properties, with Son’s implementation of a specific bimodal distribution of aspect ratios, to arrive at the composition of claim 1 with a reasonable expectation of success. We do not find persuasive Patent Owner’s arguments that Bosnyak- 392 teaches away from using nanotubes with a lower aspect ratio, or that Bosnyak-392 has an objective of maintaining longer nanotubes. See Prelim. Resp. 5–9. Patent Owner’s arguments appear to be based on a mischaracterization of Bosnyak-392, which read as a whole, discusses methods for exfoliating carbon nanotubes and physical properties of exfoliated nanotubes, such as length and diameter, that are not apparent when the nanotubes are aggregated. E.g., Ex. 1005 ¶ 37. Although Bosnyak-392 recognizes that nanotube exfoliating techniques tend to reduce nanotube length (see Ex. 1003 ¶ 28), it does not discourage the use of shorter nanotubes. Rather, it recognizes that using short and long nanotubes together can produce a composite with improved electrical and mechanical properties. See id. (citing Ex. 1005 ¶ 73).

      “Having considered both sides’ arguments as to Fintiv factors 2 and 3, we determine that the considerations of these factors weigh against exercising discretionary denial. Neither party directs us to any substantive order issued by the district court in the parallel litigation, which indicates the court has not yet considered claim construction or potential invalidity of the ’282 patent. The Markman hearing will not occur until June 2025, and the expert discovery cutoff is not until August 2025. Ex. 2002. Thus, although the parties have begun discovery as to invalidity issues, much further work remains in the parallel district court litigation. We also take into account Petitioner’s prompt filing of the Petition, as weighing against exercising discretionary denial. See Fintiv 11 (“If the evidence shows that the petitioner filed the petition expeditiously, such as promptly after becoming aware of the claims being asserted, this fact has weighed against exercising the authority to deny institution . . . .”).” slip op. at 34

      “Thus, although both parties indicate that no claim construction is necessary at this stage of the proceeding, it is apparent that they disagree as to the meaning of “discrete carbon nanotubes.” While Petitioner appears to construe “discrete carbon nanotubes” as “nanotubes that are generally individually distinct” (Pet. 13), Patent Owner argues a more restricted construction requiring that “discrete carbon nanotubes” not be reacted with other components. Prelim. Resp. 3. The evidence relating to claim 10 In quotations from the Preliminary Response throughout this Decision, we have retained bolding and underlining added to the text by Patent Owner. construction that Patent Owner offers on the current record, however, does not address its proposed restriction. See id. at 9, n. 4, citing Ex. 1001, 3:9, 5:39–40 (“The ’649 Patent describes the ‘discrete carbon nanotubes’ as, for example, ‘individually dispersed’, ‘individualized carbon nanotubes’, ‘dispersed as individual nanotubes’, and ‘essentially discrete individual fibers, not entangled as a mass.’”). 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 Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). If either party intends to argue a claim construction at trial, however, including what is the ordinary meaning of a term, they should do so in a clearly designated section of their briefing. See Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 21, 2019) (“CTPG”), 46, 49 (available at https://www.uspto.gov/TrialPracticeGuideConsolidated); O2 Micro Int’l Ltd. v.

      “During prosecution, the examiner stated that the carbon nanotubes of the applied prior art reference “are considered discrete and exfoliated . . . because they are dispersed in the composite cathode slurry mixture.” Ex. 1002, 5–6. The Board determined, however, that “without more,” the examiner’s bare statement was insufficient to address the prior art reference’s “express teaching that suggests bundling or agglomeration of carbon nanotubes.” Id. at 6 (noting that Figure 2 of the prior art reference suggested that the carbon nanotubes were in fact bundled and agglomerated). In contrast to the art and analysis provided by the examiner during prosecution, Petitioner identifies a specific disclosure in Ohata demonstrating that the carbon nanotubes are “discrete, non-agglomerated, and exfoliated.” Pet. 32–33 (citing Ex. 1004, Fig. 1(b)). In further contrast to the arguments presented during prosecution, Patent Owner identifies no disclosure in Ohata, or any other prior art reference, that would suggest that the carbon nanotubes of Ohata, Kavan, and Gong or Liu are agglomerated or non-discrete.
