“Patent Owner’s arguments do not persuasively undermine Petitioner’s position. Sakamoto expressly discloses setting the ratio of negative to positive electrode active material in the range of 1.05 to 1.30. Ex. 1005 ¶ 8. Sakamoto also explains why this range is preferable, i.e., if the ratio is roughly equal “the charge-discharge cycle performance is insufficient due to significant deterioration from charging and discharging,” and if the ratio is 10 Citations to the prosecution history of Yamaki are to the page numbers added to the lower right corner of the document. too high “too much of the compound does not participate in charging and discharging.” Id. ¶¶ 6, 8. These disclosures are sufficient to explain why one of ordinary skill in the art would have found it obvious to select the ratios disclosed in Sakamoto in Yamaki. Id. ¶ 8 (providing a secondary battery with a capacity ratio between 1.05 and 1.30 and noting that by setting the ratio within this range the resulting secondary lithium battery is “safe due to low risk of heat being generated and an explosion occurring”). We also disagree that Sakamoto teaches away from elevated voltages or from increasing the amount of lithium in circulation. See PO Resp. 29. Contrary to Patent Owner’s arguments, Sakamoto provides no general teaching against using a charge cut-off voltage above 4.2 V, or against increasing the level of lithium in circulation. Nor does Sakamoto “criticize, discredit, or otherwise discourage” the claimed invention. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Rather, Sakamoto warns against setting the reversible capacities of the positive and negative electrode substantially equal as this may result in excess lithium plating on the surface of the electrode.

“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.

“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.

“Petitioner does not appear to disagree that Markel, itself, does not convey that an electrode, or any structure identifiable as a “pad,” is positioned underneath any surface of any enclosure. Rather, Petitioner’s theory of unpatentability is premised on modification of Markel to so position such a pad. Although seemingly acknowledging that Markel contemplates a concealment technique involving molding an electrode into an exterior surface, Petitioner extrapolates from that disclosure that a skilled artisan would be motivated to try an alternative means of concealing an electrode pad by placing the pad underneath an outer layer or portion, i.e., “audio output portion 610.” See Pet. 20 (citing Ex. 1003 ¶ 135). Neither Petitioner, nor Dr. Kenny, however, meaningfully explains why a skilled artisan would have deviated from Markel’s express teachings of concealing an electrode via molding techniques to then arrive at an entirely different concealment approach of placing an electrode pad underneath the audio output portion. Petitioner’s modification proposal in that regard appears borne of hindsight bias based on the disclosure of the ’257 patent rather than any dutiful consideration of what Markel’s actual teachings would have conveyed to a skilled artisan. See Ex. 2004 ¶ 84 (Dr. Kenny explaining why Petitioner’s proposed modification to Markel to hide the electrode underneath a plastic conductive layer was based on improper hindsight). Such hindsight bias is impermissible. See, e.g., Metalcraft of Mayville, Inc. v. The Toro Co., 848 F.3d 1358, 1367 (Fed.

“We find Patent Owner’s position to be persuasive. Not only are the cover and biosensor module recited separately in the list of components of the device of claim 9, we also agree that the “disposed over” claim language establishes the configuration of two separate components relative to each other. Additionally, the claim language that requires the cover to be “configured to pass optical signals to and from the biosensor module” supports an interpretation where the cover is separate from the biosensor module, otherwise it seemingly would be passing signals to and from itself. The understanding that the cover is separate from the biosensor module in claim 9 is consistent with the Specification’s description of an embodiment that tracks the language of claim 9 and speaks of the two elements as separate, individual components, namely the statement that “[a] biosensor module may be disposed within the opening of the housing” and “[a] rear cover may be disposed over the biosensor module.” Ex. 1001, 2:59–62; see also id. at 2:56 (the same paragraph beginning with “Some embodiments . . .”). Petitioner asserts that its proposed construction is consistent with the claim language, arguing that “the word ‘cover’ naturally suggests that its role is to be ‘disposed over,’” and that “[a] cover can be part of a module just as a clear plastic lid can be both disposed over, and part of, a container, allowing a view of its contents.” Pet.

“Patent Owner argues that the proposed combination will result in a configuration “that is contrary to Honda’s teachings and its stated goals and purpose of achieving quick and efficient wireless charging.” PO Resp. 30– 31. Patent Owner’s focus on these properties is misplaced. We agree with Petitioner that characteristics such as charging speed and efficiency are not claimed. See Pet. Reply 1 (“[T]he ’783 patent does not disclose, let alone claim, sizing or other details [Patent Owner] Apple asserts are necessary for successful wireless charging.”); id. at 6 (“[C]harging speed [is] not claimed.”). Rather, the claim drafter utilized broad language to encompass a biosensor device having the capability to wireless charge through a cover— both good configurations and those that Patent Owner argues are inferior. And, even if the proposed combination does not yield a commercially viable product, as Patent Owner implies, the broad claim scope would hinder an innovating competitor’s ability to utilize and test that purported less desirable combination on the way to development of a better device. Patent Owner argues that a person of ordinary skill in the art would not have been motivated to make the proposed combination and would not have had a reasonable expectation of success in making that combination. See, e.g., PO Resp. 31. These arguments are not persuasive at least because Patent Owner’s motivation requirement and implied definition of success are not sufficiently tied to the claimed invention. See, e.g., Elekta Ltd. v. ZAP Surgical Sys., Inc., 81 F.4th 1368, 1375 (Fed. Cir. 2023) (“Reasonable expectation of success refers to the likelihood of success in combining references to meet the limitations of the claimed invention.”). Patent Owner would require a successful outcome to be “quick and efficient wireless charging.” See PO Resp. 31. In making these arguments, Patent Owner is improperly superimposing the purported goals and purpose of Honda, the secondary reference, onto the ordinary artisan. See, e.g., id. at 37–41. However, the intended purpose of a prior art reference does not control the obviousness inquiry. Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021). Our reviewing court recently explained: The [motivation-to-combine] inquiry is not whether a relevant artisan would combine a first reference’s feature with a second reference’s feature to meet requirements of the first reference that are not requirements of the claims at issue. A contrary view would run counter to established principles, including that the claim defines the invention whose obviousness is being assessed and that a skilled artisan may be motivated to combine particular features of different references, e.g., to secure some benefits at the expense of others, even when bodily incorporation would be impossible or inadvisable. Axonics, Inc. v. Medtronic, Inc., 73 F.4th 950, 957 (Fed. Cir. 2023). Petitioner’s combination yields the benefit of the addition of wireless charging capability to a biosensor device. A person of ordinary skill in the art would find that benefit to be a motivating reason to make the combination. See, e.g., Ex. 1003 ¶ 121 (Dr. Duckworth’s motivation opinion based, in part, on “Kotanagi’s own statement that its rechargeable battery can be recharged ‘in a contactless state.’”); id. ¶ 127 (Dr. Duckworth’s describing a motivating factor in Honda’s explanation “that this [charging] station passes wireless power to the wireless charging receiving coil through a rear cover glass (similar to that of Kotanagi), using the physics of induced currents and magnetic flux.”); see also Ex. 1052, 45:16–46:2 (Dr. Anthony, on cross-examination and after being asked whether wireless charging is an improvement over wired charging for a consumer watch, responding that “in some instances it could be, and in others it may not be.”). And, as to a reasonable expectation of success, Patent Owner admits that “Petitioner has presented a device configuration in which a wireless charging coil could be provided in Kotanagi’s through hole 22.” PO Resp. 56; see also id. at 3 (Patent Owner arguing that “the size of coil that could be provided in this allegedly available space would be small and would significantly limit the amount of wireless power signal transmission,” but not arguing that even Patent Owner’s purported size-limited configuration would be inoperative); see, e.g., Ex. 1003 ¶¶ 130–133 (Dr. Duckworth credibly testifying that a person of ordinary skill in the art would have had a reasonable expectation of success in combining the teachings of Kotanagi and Honda).” slip op. at 31

“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. Cir. 2011) (noting that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority . . . 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

“The definiteness requirement of § 112(a) is satisfied when “a patent’s claims, viewed in light of the specification and prosecution history, inform those skilled in the art about the scope of the invention with reasonable clarity.” Nautilus, Inc. v.

[§] 282(b)”). Proposed substitute claim 104 generically requires “in situ precipitate” and also a specific type of in situ precipitate: “in situ galvanically-active intermetallic precipitate.” Mot. Appendix A. 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.

“Module Terms each recite a “module” that is configured to perform or to oversee certain recited functionality, without reciting sufficient structure for performing that functionality. See Pet. 32. Further, as in Williamson, the word “module” in the context of the ’205 patent claims and specification is a “nonce” word, used “in a manner that is tantamount to using the word ‘means.’” Williamson, 792 F.3d at 1350–51. We therefore agree with Petitioner’s position that the rebuttable presumption against application of § 112 ¶ 6 is overcome in this case, because the Module Terms are not understood by persons of ordinary skill in the art to have a sufficiently definite meaning as the name for structure. See Williamson, 792 F.2d at 1349 (“The standard is whether the words of the claim are understood by persons of ordinary skill in the art to have a sufficiently definite meaning as the name for structure.”).

“In considering Patent Owner’s explanation, and upon further reflection, we agree with Patent Owner’s reading of the pertinent sentence. In that regard, consistent with the remainder of the Specification of the ’008 patent, it follows that the noted sentence does not alter the contours of “acquired” data to also encompass “passive” data where that premise is entirely absent from other portions of the Specification. Rather, as Patent Owner explains, the sentence is consistent with the understanding that it is “active data” that is connected to the word “acquired” and “passive data” that is connected to the word “available.” See, e.g., id. Patent Owner’s explanation alleviates the ambiguity that was postulated in the Institution Decision. We have considered Petitioner’s views to the contrary (see, e.g., Pet. Reply 21–25) but find them unavailing. In particular, Petitioner does not reconcile its position that, although acknowledging that “acquired data” is defined in the ’008 patent, the term “acquiring” is not so defined and should be regarded as an “individual word” whose meaning is somehow entirely unconnected to “acquired.” See, e.g., Pet. Reply 21. We note, as we did in the Institution Decision, that the ’008 patent states that “acquired data” and “its equivalents and verb forms” is “a type of active data.” See Inst. Dec. 30 (citing Ex. 1001, 3:25–32). We are not persuaded by Petitioner’s view (see, identifiable as a verb form of “acquired.” See PO Sur-reply 8. We determine that, in the context of the ’008 patent, it clearly is. Having considered the competing views of Petitioner and Patent Owner, we conclude that Patent Owner’s construction of the term “acquiring interest data” is consistent with, and supported by, the Specification of the ’008 patent.

To that end, we find persuasive Petitioner’s arguments in the Petition as to the proposed reasoning to combine Willner and Kitts, and also credit Dr. Lopresti’s supporting testimony. See Pet. 28–29; Ex. 1003 ¶ 118. We are mindful of the contrasting testimony referenced by Patent Owner’s declarant, Dr. Russ. See, e.g., PO Resp. 38 (citing Ex. 2011 ¶¶ 107–110).

How to collectively analyze fundamentally different types of data—Willner’s mouse vector data on one hand, and Kitts’ passive data on the other; 3. How to generate a useful confidence score that is more accurate than the scores already generated by Willner, again taking into consideration that passive data is a fundamentally different type of data than active data; assessment using the complex statistical model of Kitts; and 5.

“Dr. Ducharme’s testimony that “the spacing of the chips in Zhang would not likely be so close as to create overheating issues” (Ex. 2002 ¶ 111) is unsupported by any disclosure of the actual spacing of Zhang’s chips. Consequently, his testimony that there would be no overheating concerns in Zhang due to the spacing of the chips is entitled to little, if any, weight. Dr. Ducharme further testifies that the components of Zhang’s driver “could easily increase the temperature of the LED 19 chips on the circuit board, which can cause LEDs to generate less illumination, burn out and otherwise adversely affect their performance.” Ex. 2002 ¶ 126. Dr. Ducharme further testifies that “[i]t is well-known that excessive operational temperatures can reduce the illumination provided by the LEDs, can decrease the operational lifetime of the LEDs, and if the temperature is sufficiently high, it can cause LED junction failure and a burnt-out LED.” Id.
