      “asserts that a person of ordinary skill in the art would have had “at least an undergraduate degree in mechanical engineering, and about two years of experience designing structural systems like tactical staircases or elevated tactical systems that can be vehicle mounted and can be folded and stowed and elevated for use by personnel or equivalent experience.” Pet. 3 (citing Ex. 1021 ¶¶ 12, 13). Mr. Hayduk states his conclusion as to the proposed level of ordinary, but does not disclose the underlying facts or data on which his opinion is based. Ex. 1021 ¶¶ 12, 13. Thus, his opinion testimony is entitled to little or no weight. 37 C.F.R. § 42.65(a). Here, we give it some, but little, weight because it appears to be consistent with the general prior art discussed and cited in the record of the ’677 patent. Patent Owner does not dispute Petitioner’s proposed level of ordinary skill. See generally, PO Resp. For purposes of this Decision, based on the prior art, the sophistication of the technology at issue, and Mr. Hayduk’s Declaration testimony, we adopt, with minor modification, Petitioner’s undisputed definition of the level of ordinary skill. We determine that in this proceeding a person of ordinary skill would have had a bachelor’s degree in mechanical engineering and two years of experience designing structural systems like tactical staircases or elevated tactical systems that can be vehicle mounted and can be folded and stowed and elevated for use by personnel or equivalent experience, or an equivalent balance of education and work experience, such that more education offsets the need for some work experience, and more work experience can offset the need for coursework leading to a four-year college degree.

      “In this inter partes review, the burden is on the petitioner to show a reasonable likelihood that it would prevail on a ground of unpatentability. 35 U.S.C. § 314(a). A petitioner first must raise the issue of entitlement to a claimed priority date by “identifying, specifically, the features, claims, and ancestral application or applications allegedly lacking § 112 support for the claims based on the identified features.” Focal Therapeutics, Inc. v. Senorx, Inc., IPR2014-00116, Paper 8, slip op. at 9–10 (PTAB Apr. 22, 2014). Then, the patent owner must make a sufficient showing of entitlement to earlier filing date(s), in a manner that is commensurate in scope with the specific points and contentions raised by the petitioner. See id. Here, Petitioner asserts that “[t]he ’677 patent includes more content than the ‘022 provisional application.” Pet. 6. We do not consider this single sentence comment on “content” to provide the specificity required of comparing the disclosure of the provisional application to the claims of the ’677 patent to thereby shift the burden to Patent Owner to show entitlement to the earlier filing date. Thus, based on the record before us, for purposes is November 20, 2018, the filing date of the provisional application.” slip op. at 17

      “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 are not inclined to adopt Patent Owner’s proposal to require a specific number of years (or a fully bounded range) in the definition of the level of ordinary skill in the art. First, Patent Owner has not offered any legal authority supporting or explaining its position. Second, using the term “at least [X] years” is common practice and generally understood to be an approximation regarding the minimum level of skill of a hypothetical person—in other words, no precision can truly be expected of the specific number of years in this context. In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (“The person of ordinary skill in the art is a hypothetical person.”). The point of the exercise is to provide context for a holistic obviousness analysis. See id. (setting out “various factors” used to analyze the level of ordinary skill); Ryko Mfg. Co. v. Nu-Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991) (“The importance of resolving the level of ordinary skill in the art lies in the necessity of maintaining objectivity in the obviousness inquiry.”); Kimberly-Clark Corp. v. Johnson & Johnson, 745 F.2d 1437, 1453 (Fed. Cir. 1984) (the hypothetical person is an “an imaginary being possessing ‘ordinary skill in the art’ created by Congress to provide a standard of patentability”). We are not persuaded of a need for strict precision in the number of years of experience of a hypothetical person used in our analysis in this case. Third, Patent Owner asks for no particular relief based upon its argument. That is, even if we agreed to remove “at least,” Patent Owner does not argue that the outcome of the Decision would be any different.1 1 For example, setting the level of skill to exactly two years of experience would not serve to automatically disqualify an expert having ten years. Kyocera Senco Ind’l Tools v. Int’l Trade Com’n, 22 F.4th 1369, 1377 (Fed. Cir. 2022) (requiring that “a witness must at least have ordinary skill in the art” and stating that “it would be improper to require an expert witness to possess ordinary skill in the art and nothing more”). In conclusion, we apply Petitioner’s proposed level of ordinary skill because it is reasonably consistent with the level of skill implied in the disclosure of the ’588 patent and the cited prior art.” slip op. at 8

      “The description of “mapping” in the ’588 patent makes clear to us that it is an association of an input value from a set of input values to a corresponding output value from a set of output values. Id. at 2:44–46 (describing “the mapping table that associates non-core domain operating frequencies and corresponding interconnect operating frequencies”) (emphases added). The “association” described here in the ’588 patent is not merely describing the fact that both exist, but that knowing the value of the first causes you to know the value of the second. This is also how it is described in the claims, wherein the “mapping” is “of selectable frequencies of the graphics processing circuitry to selectable frequencies of the interconnect.” Id. at 8:63–65 (emphasis added). Or more generally, the claim recites a mapping of a frequency to a frequency. In sum, although we agree with the parties that “mapping” should be given its plain and ordinary meaning in light of the specification, we note that the parties appear to dispute whether the prior art teaches the claimed “mapping” based on differing understandings of the plain and ordinary meaning. Based on our analysis above, we determine that a person of ordinary skill in the art reviewing the ’588 patent would understand that the “mapping” limitation requires (1) frequencies mapped to frequencies and (2) that a mapping is an association of one value to a corresponding value such that knowing the graphics frequency means that you know the corresponding interconnect frequency. Further, given that the corresponding frequencies are “selectable,” we understand that to mean that there is a set of possible frequencies that are defined from which to select. Ex. 2001, 21:19–22:2. With this understanding, we can turn to the dispute over whether the prior art teaches the limitations set forth in claims 5 and 12, as no other terms require construction at this time. Realtime, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

      “Given this disclosure, we agree with the testimony of Patent Owner’s expert that Shakkarwar’s empirical calculation, by looking up the frequencies of various devices and summing them up, is not the claimed mapping of frequencies to frequencies. Ex. 2002 ¶ 44 (citing Ex. 1006, 6:8– 16, 6:49–7:17). That is, rather than teaching the use of the graphics device frequency get a corresponding interconnect frequency, Shakkarwar calculates the interconnect frequency by adding up the frequencies of all of the devices using the interconnect. Ex. 1006, 6:63–7:30; Ex. 2002 ¶ 44 (“Considerations of the hardware are addressed through empirical calculation, by knowing the requested data bandwidth of each device.”). Based on the above, we find that Shakkarwar’s table does not map a set of frequencies to a set of frequencies, and we find that the alleged mapping in Shakkarwar is not what is required by the claim because knowing the non-core device frequency in Shakkarwar is insufficient to know the required interconnect frequency. Thus, we credit the testimony of Patent Owner’s expert that Shakkarwar does not teach the claimed mapping. Ex. 2002 ¶¶ 42–45. On the other hand, the testimony of Petitioner’s expert is conclusory on this point, and fails to grapple with these differences between the claims and prior art. Ex. 1003 ¶ 140.

Id. at 7:10–13. By looking up the bandwidth needs of each individual device in use, the system can determine the total bandwidth need. Id. at 7:5–17. For example, if one device requires 20 Megabits of data and the second device requires 10 Megabits of data, then the data rate (bandwidth) required will be 30 Megabits of data. Id. at 7:13–17. If the required bandwidth is different from the current bandwidth, then the current bandwidth must be modified. Id. at 7:18–26.

      “Pet. 10. Patent Owner provides a construction for the term “independent” of claim 1. PO Resp. 12–18. For context, claim 1 requires first and second domains, wherein “each of the first and second domains [] operate at an independent voltage and frequency.” Patent Owner provides its analysis and concludes that claim 1 requires that the voltage and frequency of the first and second domains to be “controlled separately from one another.” PO Resp. 14, 15. We disagree with Patent Owner’s conclusion. In particular, we note that Patent Owner is attempting to add a “control” limitation to the claim. The claim does not require independent control of the first and second domains, it requires them “to operate at an independent voltage and frequency.” That is, by the plain language of the claims, what is independent is the voltage and frequency of the first domain compared to the voltage and frequency of the second domain. Patent Owner identifies many passages in the ’833 patent specification allegedly supporting its position, but we do not find any of these passages persuades us to agree with Patent Owner’s position. See PO Resp. 12–14 (citing Ex. 1001, 1:13–17, 1:63–66, 7:59–62, 8:27–31, 8:38– 46, 10:4–8). These passages mostly state that the domains are independent, which we understand to mean “separate” in this context. Ex. 1001, 1:63–66, 7:59–62, 8:27–31, 8:38–46, 10:4–8; accord PO Resp. 14 (summarizing these citations and concluding that “the term ‘independent’ is used in its ordinary sense to mean ‘separate.’”); Ex. 2002 ¶ 33 (same). One passage is similar to the claim language, and recites that a core can be “of an independent power domain and can be configured to operate at an independent voltage and/or frequency.” Id. at 8:27–31. We see nothing in these passages that would require independent control as opposed to “operate at an independent voltage and frequency” as claimed. Instead, in the one passage that is similar to the claim language, it is clear that what is “independent” is the “voltage and/or frequency.” Id. at 8:27–31. Patent Owner then cites to another batch of passages from the ’833 patent and concludes that “a person of ordinary skill in the art would recognize that the ’833 patent is describing a situation in which voltages and/or frequencies of the different domains are controlled separately from one another.” PO Resp. 14–15 (citing Ex. 1001, 1:56–60, 1:63–66, 2:22–25, 2:32–36, 5:9–12, 5:21, 5:27–44, 7:20–24, 8:38–42, Fig. 1; Ex. 2002 ¶ 33). Most of these passages describe the domains being allocated portions of a power budget. See Ex. 1001, 1:56–60, 2:22–25, 5:28–40, 7:20–24, 8:38–42. One passage is similar to the prior batch of citations, stating that the domains themselves are independent. Id. at 1:63–66.

Last cited by Patent Owner is Figure 1, which has a box labeled “Control First and Second Domains Frequency and Voltage.” Id., Fig. 1 (item 130). Reviewing the cited passages and the figure, we find that the power control unit allocates or controls power. However, the claim is not directed to the power control unit and it does not use the word “control.” The claim requires the first and second domains to have independent voltages and frequencies, and we fail to see any support in the specification to add an additional requirement for independent control of the first and second domains.

We agree with Patent Owner and credit its expert that Nussbaum is concerned with the power settings of each individual core, GPU, or other computational unit. Ex. 2003 ¶ 63. Even if, in one passage, Nussbaum talks about power reallocation in “computational units, such as the CPU or [GPU],” in context it is clear that the allocations remain on the individual, e.g., core, level. Ex. 1007 ¶¶ 19– 20, 21 (Table 1), 23 (Table 2), 24. First, in the sentence just cited, Nussbaum disparages treating units homogenously, i.e., adjusting them in groups or domains (as required by claim 13). Id. ¶ 19. Then, Nussbaum praises distributing power “among the active cores or other computational units,” i.e., on an individual or core level. Id. In this phrase, Nussbaum is not using “computational units” as a word meaning “CPU,” because Nussbaum already directly references the “cores” in the phrase. Id. Nussbaum later discusses figuring out how each core reacts to power changes, in order to determine which cores can better exploit additional power. Id. ¶¶ 25–28. For these reasons, we credit the testimony of Patent Owner’s expert that Nussbaum does not disclose allocating power to a plurality of cores as a single domain (Ex. 2002 ¶ 63), which is consistent with the above-noted disclosures of Nussbaum.” slip op. at 15

Instead, Patent Owner challenges a separate, general rationale that Petitioner made at the beginning of its ground. See Pet. 69. Rationales that are broad and general may be persuasive. Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 797 (Fed. Cir. 2021) (“[R]ationale[s] [are] not inherently suspect merely because [they’re] generic in the sense of having broad applicability or appeal.

We need not evaluate Petitioner’s general rationale here, however, because we find Petitioner’s unrebutted, specific rationale arguments about providing a user interface to edit or revise the power sharing values to be persuasive. See Pet. 77–78 (citing, e.g., Ex. 1029 ¶ 236). In particular, we agree with Petitioner that providing a user interface to allow a user to edit the power tables, as taught in Finkelstein, would have been a routine and obvious modification to Conroy. As Petitioner’s expert points out, even beyond the teachings of Finkelstein, it was known in the art to allow users control over power allocation. Ex. 1029 ¶ 236 (citing Ex. 1026, 11:13–27 (describing a “user preferences database” containing “parameters and procedures for how to apportion power among various devices”); Ex. 1028 ¶ 17 (“The [power allocation] preference might be determined . . . based on a selection by a user of the system (e.g., via a graphical interface).”)). Thus, Petitioner’s proposed combination is an example of using a known feature to provide a known benefit. The known feature is a user interface, and the known benefit is allowing the user to indicate their preferences through the interface. See Ex. 1029 ¶ 236; KSR, 550 U.S. at 417 (“[A] court must ask whether the improvement is more than the predictable use of prior art elements according to their established functions.”). Based on the record before us, we determine that Petitioner has established a reason with rational underpinnings for combining the user level control interface of Finkelstein with the power management system of Conroy.” slip op. at 33

      “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.

      “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.

      “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

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.

A motivation to combine may be found “explicitly or implicitly in market forces; design incentives; the ‘interrelated teachings of multiple patents’; ‘any need or problem known in the field of endeavor at the time of invention and addressed by the patent’; and the background knowledge, creativity, and common sense of the person of ordinary skill.” ZUP, LLC v.

However, if we were to apply Petitioner’s proposed level of skill, our Decision would not be affected.” slip op. at 9

      “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. We agree with this testimony, which as discussed below, is consistent with Salam. Dr. Ducharme’s testimony concerning overheating issues caused by the driver components contradicts Patent Owner’s ’s contention that there would not be “an overheating issue with Zhang’s LED exit sign circuit in Figure 2.1.” PO Resp. 30. Regardless of whether Zhang’s LEDs in Figure 2.1 have a heat problem or not, Salam teaches the advantages of using a heat sink. Salam teaches that a heat sink will result in a higher efficiency of the LEDs and improved life. Ex. 1006, 16:38–43. The Federal Circuit, in DyStar Textilfarben GmBH & Co v. C.H. Patrick Co., 464 F.3d 1356 (Fed. Cir. 2006), stated that “the desire to enhance commercial opportunities by improving a product or process is universal–and even common-sensical . . . the proper question is whether the ordinary artisan possesses the knowledge and skills rendering him capable of combining the prior art references.” Id. at 1368. Dr. Ducharme testified that a person of ordinary skill in the art “would have an understanding of the generation of heat and using a heat sink to remove unwanted heat from electronics and LED lighting devices.” Ex. 1102, 23:18–24:3. Dr. Ducharme’s testimony is consistent with Petitioner’s contention that the combination of Zhang and Salam “would have been a straightforward combination of known components and technologies, according to known methods, to produce the predictable result of reducing/ mitigating heat effects in a circuit.” Pet. 17 (citing Ex. 1002 ¶ 106). Patent Owner next contends it would be extremely burdensome and costly to modify Zhang to add a heat sink layer because “each of the multiple chips mounted and epoxied to Zhang’s circuit board in the exit sign would have to be modified.” PO Resp. 30 (citing Ex. 2002 ¶ 112). Dr. Ducharme’s testimony repeats the Patent Owner Response verbatim and is entitled to little, if any, weight. Ex. 2002 ¶ 112. Nonetheless, this contention is unavailing because it is based on Patent Owner’s bodily incorporation of Zhang and Salam. Patent Owner next contends that a person of ordinary skill in the art” slip op. at 27
