    “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.

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.

    “In other words, even if we accept that Dr. Howle has some experience designing medical devices and components, and that those experiences represent work designing products similar to mechanical beverage systems, Patent Owner fails to direct the Board to evidence sufficient to establish that this experience, in the aggregate, amounts to “at least five years” or involved “experience with sensors for recognizing identifiers.” Dec. 8 (adopting Patent Owner’s own proposed definition of ordinary skill in the art); see Sur-reply 3 (citing Ex. 1066, 34:16–35:9; Ex. 1067, 101:3–12, 102:30– 104:9; Ex. 2017 ¶¶ 3, 4) (failing to establish adequately, if at all, how Dr. Howle’s qualifications include the requisite minimum five-year period of relevant design experience). Accordingly, we determine that Dr. Howle is not qualified to offer expert testimony from the perspective of a person having ordinary skill in the art in this proceeding.12 Kyocera Senco Indus. Tools Inc. v. Int’l Trade Comm’n, 22 F.4th 1369, 1376–78 (Fed. Cir. 2022). The Federal Circuit has made plain that, “[t]o offer expert testimony from the perspective of a skilled artisan in a patent case,” including the issue of patent “validity,” the “witness must at least have ordinary skill in the art.” 12 To be clear, we are not saying that a witness supplying expert opinions must have satisfied the requirements of the level of ordinary skill in the art on or before the priority date of the challenged patent, which Patent Owner seems to understand. See Sur-reply 4–5. Instead, we evaluate whether Dr. Howle had at least the requisite qualifications of a person having ordinary skill in the art by the time he rendered his opinions. Osseo Imaging, LLC v. Planmeca USA, Inc., Appeal No. 2023-1627, slip op. at 7 (Fed. Cir. Sept. 4, 2024) (“[A]n expert can acquire the necessary skill later and develop an understanding of what a person of ordinary skill knew at the time of the invention,” however, where “the expert was not a person of ordinary skill at the time of the invention may well be used during cross-examination to undermine the credibility of the expert.”); see id., slip op. at 5–6 (affirmatively quoting Kyocera). Id. (Board’s emphasis). “Without that skill, the witness’[s] opinions are neither relevant nor reliable.” Id. at 1377. “‘Admitting testimony from a person . . . with no skill in the pertinent art serves only to cause mischief and confuse the factfinder.’” That testimony would ‘amount[ ] to nothing more than advocacy from the witness stand.’” Id.

    “In Petitioner’s contrary view, Jarisch teaches how to move a code in a centrifugal brewing system to the bottom of the flange and how to configure a light-conductive material so that the detector’s light source will reach the bottom of the flange. Pet. 45–46; Reply 21–22 (Ex. 1003 ¶¶ 194–195; Ex. 1005 ¶¶ 82–84, Fig. 5). Although Figure 61 of Yoakim discloses a flare in its brewing chamber, bodily incorporation is not required, and we are directed to no persuasive argument or evidence that Yoakim could not be configured with a straight chamber, as depicted in Figure 5 of Jarisch. We credit the testimony of Mr. Jobin that a person of ordinary skill in the art would have sought to place the code at the bottom of the flange and would have had a reasonable expectation of success in so doing. Ex. 1003 ¶ 184. For reasons explained above, we assign little or no weight to Dr. Howle’s conflicting testimony because he has little or no experience designing a mechanical beverage system or similar product. See supra 10– 16. Petitioner lays out persuasive reasons why Dr. Howle’s testimony, on this particular point, is “conclusory” and rests on “bodily incorporation” of the references. Reply 24; see id. at 22–24 (pointing out with particularity fundamental flaws in Dr. Howle’s opinions); In re Mouttet, 686 F.3d 1322, 1332 (Fed.

In addition, Patent Owner contends that Yoakim requires that the capsule holder be capable of receiving a set of multiple volume capsules and that there is a “snug fit” to avoid “unbalances.” Sur-reply 8 (citing Ex. 1004 ¶¶ 205, 479, 484, 507, 512). According to Patent Owner, Petitioner does not explain adequately how the use of Jarisch’s “straight chamber” with a capsule holder that does not engage with the side wall of the capsule would allow insertion of multiple volume capsules or permit a “snug fit” in the modified device of Yoakim. Id. at 8–9. Patent Owner’s view that Yoakim discloses the use of certain capsules which might not fit into a device with Jarisch’s non-flared structure is ineffective to undercut the sufficiency of Petitioner’s showing on this point. Petitioner is not seeking a bodily incorporation of Yoakim and Jarisch and, in any event, other embodiments of Yoakim do not require the type of flared capsule identified by Patent Owner. Ex. 1004, Fig. 63. Furthermore, we credit the testimony of Mr. Jobin that one of ordinary skill in the art would have understood how to design the chamber of Yoakim to allow reading of a barcode on the underside of the flange. Ex. 1003 ¶¶ 187–195. With respect to the argument that the use of Jarisch’s design would not allow a snug fit, we are directed to no persuasive evidence that Jarisch’s lack of contact between the capsule side wall and the holder would render the device inoperable or less effective. Resp. 39–40; see Reply 22 (citing Ex. 2019, 36:18–37:6). Indeed, as Petitioner points out, Jarisch indicates that its device, including its capsule holding means, allows the capsule to be successfully driven in rotation.

    “Ex. 2027, 20:25–21:5 (emphasis added). The disclosure that the “magnesium composite” of “[t]he present invention” “includes at least 50 wt% magnesium” is unambiguous and constitutes strong evidence that the inventors were not in possession of a magnesium composite with less than 50 wt. % magnesium, or additive concentrations above 50 wt. %. See SciMed Life Systems, Inc. v. Advanced Cardiovasular Systems, Inc., 242 F.3d 1337, 1343 (Fed. Cir. 2001) (noting that a description of the “present invention” as having a particular structure “is strong evidence that the claims should not be read to encompass the opposite structure”). Consistent with this conclusion, the original claims of the ’295 application all limited the additive material in the composite to 0.05 wt %–45 wt %. Ex. 2027, 26:1– 13, 29:9–15. Likewise, in each example where copper, nickel, or cobalt additives are used in the range recited in the proposed substitute claims, the magnesium composite is “over 50 wt% magnesium,” and any claims that do not require this range of magnesium are limited to an additive range of “about 0.05 wt%–45 wt% of said mixture.”8 Ex. 2027, 6:13–7:4, 7:16–19, 8 Written description support is considered from the view point of the ordinarily skilled artisan. Ariad Pharms., Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). Patent Owner, bearing the burden to show written description support in any priority application for which it seeks the benefit of its filing date, provides no testimony from an ordinarily skilled artisan regarding written description support in the ’295 application, or any evidence to show what such an artisan would conclude from the express disclosures of the ’295 application. Lectrosonics, Paper 15 at 7; In re NTP, 654 F.3d 1268, 1276 (Fed.

Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120”). Where there is any ambiguity in the disclosures of the ’295 application, the absence of supporting testimony tends to cut against 26:2–31:2; see Ex. 1005 ¶¶ 12, 13, 18, 19, 16–21, 26, 28, claims 16–21, 26– 28. In view of the foregoing, we are not persuaded that Patent Owner has demonstrated that the inventors of the priority applications were in possession of a magnesium cast composite that included less than 50 wt. % magnesium, or greater than 50 wt. % additives. As proposed substitute claim 104 encompasses a magnesium cast composite with up to 90 wt. % additives, and therefore as little as 10 wt. % magnesium, Patent Owner has not demonstrated that the full scope of this claim finds written description support in any application prior to the ’915 application, filed on October 12, 2018.” slip op. at 17

Although this claim would have best been clarified by Patent Owner after seeking preliminary guidance on its Motion to Amend, upon review of the written description, claims, and figures of the ’740 patent, as well as Patent Owner’s clarification in its Reply to the Opposition, we agree with Patent Owner that one of ordinary skill in the art would have understood that the “in situ galvanically-active intermetallic precipitate” is merely a more complete description of the “in situ precipitate” mentioned earlier in the sentence.

    “When deciding whether issue preclusion applies, we consider whether: (1) a prior action presents an identical issue; (2) the prior action actually litigated and adjudged that issue; (3) the judgment in that prior action necessarily required determination of the identical issue; and (4) the prior action featured full representation of the estopped party. VirnetX Inc. v Apple, Inc., 909 F.3d 1375, 1377 (Fed. Cir. 2018) (citing Stephen Slesinger, Inc. v. Disney Enterprises, Inc., 702 F.3d 640, 644 (Fed. Cir. 2012)). To the extent Petitioner asks us to consider the 01473 IPR institution decision for issue preclusion, we do not. In that decision the Board reached a finding based on the institution standard (showing of a “reasonable likelihood that the petitioner will prevail,” 35 U.S.C. § 314(a)) rather than proof by a preponderance of the evidence, which is before us now (35 U.S.C. § 316(e)). Ex. 1016. Thus, issues before us here were not presented and adjudged in that institution decision. Regarding the 01473 IPR adverse judgment decision, that decision did not require determination of any issues before us, as that decision was based on Patent Owner canceling the challenged claims rather than any determination regarding unpatentability that had been shown by a preponderance of the evidence. Ex. 1014. 2. Collateral Estoppel With Respect to the 00571 IPR We find and determine that the final written decision in the 00571 IPR, and the Federal Circuit’s CommScope decision affirming that decision, satisfies the conditions for applying collateral estoppel because the 00571 discloses materially the same claim limitations7 challenged here, and Patent Owner had full representation throughout the proceedings. Setting aside the factors of issue preclusion for a moment, our reviewing court’s affirmance of our final written decision in CommScope is persuasive authority that supports our prior construction of “packetizing” and Petitioner’s showing that Wu teaches the disputed packetizing limitations under that construction. In addition, issue preclusion prevents Patent Owner from re-litigating the issue of whether Wu teaches materially the same disputed limitation. See Pet. Reply 24; Ex. 1017, 31–34 (final written decision determining obviousness of claims 9, 10, 14, and 16 of the ’473 patent over Wu and Sabat-426); Ex. 1072, 5 (summarizing the final written decision regarding the packetizing limitations), 10–16 (finding no error in the determinations regarding the packetizing limitations).” slip op. at 12

Robertson, 169 F.3d at 745 (“The [prior art] patent does not expressly include a third fastening means for disposal of the diaper, as claim 76 requires.”). In further contrast to this case, Robertson addressed mechanical elements of a product (fasteners for disposable diaper), not steps in a process.

    “Upon review of the record and the parties’ arguments as a whole, we agree with Petitioner that Saito discloses a driver, as that term is used in claim 1 of the ’551 patent. First, our construction of “driver” is broad, constituting any “program, circuitry, or device used to power other programs, circuits, or devices.” And, consistent with the structure of claim 1 of the ’551 patent, this construction does not require that the identified circuit or device actually generate power, only provide power to another device or circuit. switch that turns on or off a power source. Rather, the circuit of Saito monitors the voltage provided at both node A 107 and node B 715 and, depending on the reported voltages, switches between voltage sources to provide power to the LEDs. In this way, the voltage applied to the LED circuit is maintained within a range of roughly 16 and 30 Volts, and the LEDs are driven for a prolonged period of time by capacitors 106 and 107, which Saito explains “cut[s] down the consumption of electric current” and results in more efficient use of power.

Neither the plain claim language nor the specification requires the phosphor coating to be directly attached to the substrate. Limitation 1(c) recites, wherein the LED chips comprise a phosphor coating to produce a change in a color or a quality of light emitted from the LED chips, wherein the LED chips, the power connection leads, and the phosphor coating are formed or mounted to a flexible substrate that is sufficiently flexible to be formed into a cylindrical shape[.] Ex. 1001, 22:7–12 (emphasis added). The claim is inartfully written, as it requires the LEDs to comprise a phosphor coating but then separately recites that the LED chips and the phosphor coating are formed or mounted to the substrate. But Petitioner correctly explains that the plain meaning requires that “the LED chips comprise a phosphor coating” and that “the [same] phosphor coating” (included in the LED chips) is “formed or mounted to a flexible substrate.” Reply 2. In other words, the use of the term “the” before “phosphor coating” indicates reliance on the antecedent basis of “LED chips comprise a phosphor coating,” and thus the same coating of the LED chips is formed or mounted to the substrate. Logically, by including a phosphor coating with the LED chips, which are formed or mounted to the substrate, the coating of these chips is also indirectly formed or mounted to the substrate. Conversely, it would be illogical to conclude that the claim recites two phosphor coatings, one attached to the LED chips and another attached directly to the substrate, because the structure of the claim refers to a single phosphor coating of the LED chips. Even Patent Owner concedes that the claim encompasses the phosphor coating indirectly being mounted or attached to the substrate (in addition to being directly attached).

Briefly, we summarize our findings, and then we address the parties’ arguments in more detail.

For example, Martin teaches that “[t]he number of LEDs in the monolithic array may be selected to achieve a particular voltage drop across each device.” Ex. 1006 ¶ 22. Martin further explains, “[t]he voltage across each of the individual LEDs in the array is the line voltage divided by the number of LEDs in series,” and “[t]he number of LEDs is chosen such that the maximum voltage across each individual LED during the peak in the alternating current cycle is low enough so as not to damage the LEDs.” Id.

(“At 120 RMS volts, the peak voltage will be about 180V [correction: 169.71 V],” and if the LEDs “can tolerate a maximum forward voltage of 4.5V, at least 38 LEDs connected in series are required.” (38 LEDs x 4.5 V = 171 V)); PO Resp. 41–42 (“While Martin references ‘about 180V,’ both parties agree that the correct value of the peak voltage Vp is 169.71 V.” (citing Ex. 1002 ¶ 127)).

This statute provides that “[a] petitioner in an inter partes review may request to cancel as unpatentable 1 or more claims of a patent only on a ground that could be raised under section 102 or 103 and only on the basis of prior art consisting of patents or printed publications.” § 311(b) (emphasis added). Patent Owner contends that Martin is not available as prior art under 35 U.S.C. § 311(b) because it is not a patent or printed publication and is only prior art under 35 U.S.C. § 102(e). PO Resp. 22. Patent Owner argues that documents are “printed publications” as of the date they become available to the public, and Martin became public on its publication date of October 21, 2004, after the February 25, 2004 priority date of the ’979 patent. Id. at 23. Patent Owner raises a similar argument for the Soules-II reference in Ground 6. Id. at 25– 26. Petitioner responds that the AIA framework permits the use of § 102(e) prior art in IPR proceedings, unlike formerly available covered business method review (CBM) proceedings, which restricted challenges to § 102(a) prior art. Reply 29. We agree. The statute governing the formerlyavailable CBM proceeding explicitly limits challenges based on “prior art that is described by section 102(a).” AIA § 18(a)(1)(C). In contrast, § 311(b) more broadly permits challenges “on the basis of prior art consisting of patents or printed publications.” The broader language in § 311(b) implies that unlike CBMs, IPRs are not limited to challenges solely under § 102(a) prior art. The parties cite to no Federal Circuit decisions that squarely address this issue. However, the Federal Circuit has applied § 102(e) patent application publication prior art in appeals from IPR proceedings. See, e.g., Purdue Pharma L.P. v. Iancu, 767 Fed. App’x 918, 920–21, 926 (Fed. Cir. 2019) (nonprecedential) (determining that a § 102(e) patent application publication was available as prior art in an IPR). The Board has also long permitted challenges based on patent application publications under § 102(e). See, e.g., Idle Free Sys., Inc. v. Bergstrom, Inc., IPR2012-00027, Paper 14 at 27 (PTAB Jan. 31, 2013) (instituting trial over § 102(e) ground based on a patent application publication). We therefore find Patent Owner’s § 311(b) argument unpersuasive.” slip op. at 34
