The standard for instituting an inter partes review is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted unless “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” For the reasons provided below, we determine that Petitioner has demonstrated a reasonable likelihood that at least one claim of the ’704 patent is unpatentable, and we institute an inter partes review. 37 C.F.R. § 42.108(a).” slip op. at 2

      “1. “deployment scenarios” Claim 1 recites a machine learning model that “includes model parameters associated with values corresponding to one or more deployment scenarios.” Ex. 1001, 14:23–25. The ’704 patent provides a list of “deployment scenarios” that includes “a cellular base station . . . in an in-line mode.” Id. at 2:39–41; see also id. at 2:38–65 (entire list). The “in-line mode” is shown in Figures 6A and 7A, in which machine learning model 103 is placed “between an input 601 and an amplifier 603.” Id. at 10:38–42, 10:47–50.

      “associated with the base station as claimed, focusing on the words “associated with.” Prelim. Resp. 26–28. Patent Owner argues that Petitioner’s position is that the model is “implemented within” the base station, but that the claim requires the model to be “associated with” the base station. Id. at 27. On this record, with no claim construction offered, we fail to see how Patent Owner construes a model “implemented within,” i.e., used in, a base station to not also be “associated with” the base station. That is, it would seem that a model used in a base station is associated with that base station. Accordingly, we do not find Patent Owner’s argument persuasive on this preliminary record.” slip op. at 12

      “We regarded Petitioner’s description as consistent with the prior art before us. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself may reflect an appropriate level of skill). Thus, for the purpose of our Institution Decision, we adopted Petitioner’s proposal. Institution Dec. 8–9. In its Response, Patent Owner does not take exception to our definition. See PO Resp. 3. However, Patent Owner asserts that a person of ordinary skill in the art “would have the equivalent of a bachelor’s degree in Computer Science, Computer Engineering (or a related field) and approximately two years of work experience with computer architecture design.” Id. We find Patent Owner’s and Petitioner’s definitions of a person of ordinary skill in the art are not meaningfully distinguishable from one another. Accordingly, we do not see the need to modify our adoption of Petitioner’s proposed level of ordinary skill in the art. However, our findings would not change even under Patent Owner’s proposed level of skill in the art.” slip op. at 13

      “We are satisfied that Mr. Jones qualifies as a person of ordinary skill in the art. See, e.g., Ex. 2008, 1 (“Summary” including “embedded systems including both software and hardware”, “Representative Design Work” including, e.g., “Design and implement multiple device drivers for complex Integrated circuits,” “Design of a highly fault tolerant, distributed data acquisition and control, system for a rebreather . . . system architecture, hardware design and layout, embedded firmware, documentation,” “hardware and firmware design,” “[h]ardware and firmware for controlling a unique, battery powered diesel burner…”), 2–3 (list of Publications). We are also satisfied that Mr. Jones’ degree in Electrical and Mechanical Engineering is sufficiently “equivalent” to a degree in Computer Engineering or Computer Science. See PO Sur-reply 11. We decline to give Mr. Jones’ declaration no weight for several additional reasons. One, Petitioner has not moved or otherwise sought to exclude Mr. Jones’ declaration, nor has Petitioner filed an objection. See Pet. Reply 2–5; see also Hearing Tr. 32, 33:15–34:8. Two, we are afforded broad discretion in assigning weight that is to be accorded expert testimony. See Yorkey v. Diab, 601 F.3d 1279, 1284 (Fed. Cir. 2010) (“[T]he Board was well within its discretion to give more credibility to [one expert over another] unless no reasonable trier of fact could have done so.”); see also CTPG5 34–36. In sum, Petitioner has not persuaded us that Patent Owner’s expert’s testimony should be given no weight because Mr. Jones is not qualified as a person of ordinary skill in the art according to our definition. See Pet.

      “Patent Owner did not challenge Petitioner’s position on these terms. See Prelim. Resp. 1–13. We determined there were no claim terms that needed to be construed in our Institution Decision. See Institution Dec. 9– 10. Post-institution, Patent Owner does not dispute Petitioner’s construction of these terms and “does not believe either term requires construction, because . . . Petitioner fails to demonstrate obviousness regardless of how these terms [(“lockstep is recoverable” and “loss of lockstep is recoverable”)] are construed. PO Resp. 2. We agree with Patent Owner that no claim construction is necessary for purposes of this Decision. That is, we do not discern any claim terms that are in controversy on the full record.

      “We find Mr. Jones’ testimony amounts to conjecture because it is unsupported by evidence, for the reasons explained by Petitioner. See Pet. Reply 10–11; Ex. 2007 ¶ 32; see 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight”). However, we find that Dr. Brogioli provides sufficient persuasive evidence as to how firmware FRC logic would be used and modified in the Bigbee/Nguyen combination. See Ex. 1002 ¶¶ 57–58, 96–98. As discussed above, Bigbee uses firmware FRC logic to check for an error within a processor core. See Ex. 1005 ¶¶ 35–37, Fig. 4A. Bigbee’s firmware FRC logic does not determine if lockstep is recoverable. Id. Similar to Bigbee, Nguyen also uses firmware FRC logic to check for an error within a processor core. See Ex. 1006 ¶¶ 9, 18, Fig. 7. However, the difference is that Nguyen’s firmware FRC logic determines if lockstep is recoverable. Id. We find for the reasons given by Petitioner and Dr. Brogioli including those summarized supra, that it would have been obvious to one of ordinary skill in the art to modify Bigbee by implementing Nguyen’s determination in firmware. Pet. 33–35 (citing, e.g., Ex. 1002 ¶ 94 (stating that “[i]mplementing logical steps in firmware was known in the art”); ¶ 95 (stating that Bigbee’s system “is compliant with well-known industry standards”); ¶ 98 (stating that “firmware is flexible” and “can be modified after production, updated, and supported relatively quickly and inexpensively.”)). In contrast, Patent Owner’s arguments fail to convince us that a person of ordinary skill in the art, having knowledge of Nguyen’s teaching of determining lockstep recovery, would not have able to modify Bigbee’s firmware FRC logic to determine if lockstep is recoverable. See KSR, 550 U.S. at 421 (“A person of ordinary skill is also a person of ordinary creativity, not an automaton.”); see also id. at 418. Accordingly, Petitioner has presented reasoning, with rational underpinnings, that a person of ordinary skill in the art would have had reasons to modify Bigbee’s firmware FRC logic based upon Nguyen’s teachings and would have had a reasonable expectation of success in doing so. Accordingly, we find for the reasons given that Petitioner demonstrates by a preponderance of the evidence that this element is taught or suggested by the Bigbee/Nguyen combination.” slip op. at 29

Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (discussing the burden of proof in inter partes review). A claim is unpatentable under 35 U.S.C. § 103 if “the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious . . . to a person having ordinary skill in the art to which said subject matter pertains.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of skill in the art; and (4) when in evidence, objective indicia of non-obviousness.

      “As to the claim requirement that the direct memory access device concurrently write the packet buffer memory and the protocol stack layer memory, Petitioner asserts that neither Cornett nor Paatela explicitly describes the timing of packet writing. Pet. 42. Petitioner asserts, however, that Nelson discloses writing a packet header separately and in parallel with writing the entire packet. Id. (citing Ex. 1006, 6:66–7:4; Ex. 1003 ¶ 89). Indeed, Nelson explains that the parallel storage action “avoid[s] having to read the frames out of the [larger frame] buffer” when reading a header, which eliminates the need for a separate reading step and “allows the routing decision to be made before the [frame] buffer becomes available.” Ex. 1006, 2:1–22 (containing the quoted language), 7:1–4 (describing “parallel . . . storage”). Petitioner asserts that it would have been obvious to write the packet header at the same time as writing the entire packet in Cornett, because Cornett, Paatela, and Nelson are concerned with speed, and writing in parallel would increase speed (vs. writing serially). Id. at 43–44 (citing Ex. 1003 ¶ 90); see also id. at 26 (similar argument). Reviewing Petitioner’s position with respect to independent claim 13, we determine that Petitioner has addressed each limitation in sufficient detail and with adequate citations to the record. Petitioner has also provided sufficient reasons for combining the teachings of Cornett, Paatela, and Nelson with a reasonable expectation of success. Reviewing the record before us, we determine that Petitioner has established a reasonable likelihood of success in showing that claim 13 would have been obvious in view of Cornett, Paatela, and Nelson.” slip op. at 11

Dr. Brogioli testifies that “[a person of ordinary skill] would have been motivated to implement the processors in Fox as lockstep processors to improve reliability and availability of Fox’s server system for critical processes, for which higher reliability and availability of the system are desired.” Brogioli Decl. ¶ 90. He further testifies that “[a person or ordinary skill] also would have been motivated to implement in Fox the error detection logics that detect loss of lockstep together with the lockstep processors as taught by Safford to implement lockstep functions and further improve availability of the system.” Id. He testifies that “[a person of ordinary skill] would have understood how to implement Fox’s processors as lockstep processors with error detection logics and expect success. [A person of ordinary skill] would only have applied well-known configurations and ordinary hardware and software configuration skills.” Id. ¶ 91. Dr. Brogioli provides additional reasons motivating the combination. Id. ¶¶ 92–99. Petitioner contends that “Arai discloses switching the role of a failing processor with a spare processor.” Pet. 10. Dr. Brogioli testifies that “[a person of ordinary skill] would have been motivated to incorporate Arai’s teaching of transferring processor context from the failing processor to the spare processor not to interrupt the operating system and its running applications as desired by Fox.” Brogioli Decl. ¶ 109. He reasons that “[a person of ordinary skill] would have understood that incorporating Arai’s benefit of switching the role of the failing processor to the spare processor without affecting the operating system and running applications, which is expressly taught as desirable by both Fox and Arai and well known in the art.” Id. ¶ 110. Petitioner asserts that a person of ordinary skill also would have been motivated to further combine these references with Landry. Pet. 33–35. Dr. Brogioli testifies that “Landry discloses a fault-tolerant boot process that dynamically designates a functional CPU as logical CPU0 that performs the unique functions of a boot processor.” Brogioli Decl. ¶ 147. He testifies further that “[a person of ordinary skill] would have understood Landry’s process would have been a suitable option for selecting a boot processor in Fox’s system consistent with the initialization protocol of the IA-32 multiprocessor system.” Id.

      “prevail in showing that it would have been obvious to use blue light with a wavelength that is greater than 440 nm. Basin-2007 does not specify a specific wavelength for the blue light, but, as Patent Owner acknowledges, “blue light is generally emitted in the range of 380 to 500 nm.” Prelim. Resp. 55; see Ex. 1002 ¶ 121. Thus, the question is whether a skilled artisan, when looking for which wavelength to use, would have found it obvious to use anything in the half of the blue-light range that is greater than or equal to 440 nm. On its own, this overlap in ranges would be strong evidence of obviousness. See Galderma Lab’ys, L.P. v. Tolmar, Inc., 737 F.3d 731, 738 (Fed. Cir. 2013). Petitioners show even more. Basin-2005 discloses that there is an “assum[ption]” that blue-light LEDs emit “in the range of 420-490 nm.” Ex. 1006 ¶ 30 (cited in Pet. 25). Basin-2005 additionally teaches that its “blue, UV, or near UV LED[s]” are “relatively easy to implement and consistently produce[] the desired white light temperature.” Id. ¶ 6 (cited in Pet. 25). Furthermore, Shimizu and Stokes indicate that people were using higher wavelength blue-light in their LEDs. See Pet. 8, 24–25 (citing sources). Because a skilled artisan would have needed to select some wavelength for the blue light disclosed in Basin-2007, at this stage, we conclude that the skilled artisan would have found it obvious to include wavelengths from the higher end of the range—as disclosed in so many references. Basin-2007 discloses using a “conventional white light LED.” See Ex. 1005 ¶ 21. As evidenced by Shimizu and Stokes, the conventional white light LED sources used blue light with wavelengths greater than or equal to 440 nm. See Ex. 1002 ¶ 121 (citing sources). Patent Owner argues that “quantum efficiency” considerations would lead to using lower wavelengths, but Patent Owner does not explain why these same considerations did not convince Basin-2005, Shimizu, or Stokes to use lower wavelengths. Based on our review of the current record, we find that Petitioner has demonstrated a reasonable likelihood of proving that the combined teachings of Basin-2005 and Basin-2007 render claim 1 unpatentable as obvious.” slip op. at 27

      “October 25, 2024, from counsel for Patent Owner, Patent Owner requested authorization to file “a request for adverse judgment against itself under 37 C.F.R. § 42.73(b).” Ex. 3003 (emphases added). Our Rule 42.73(b) states “A party may request judgment against itself at any time during a proceeding.” The Board granted Patent Owner’s request. Ex. 3003. Patent Owner then filed its “Request for Adverse Judgment Pursuant to 37 C.F.R. § 42.73(b).” Paper 11 (Request for Adverse Judgment). This Request, however, stated, in error, that Patent Owner requested “adverse judgment against Petitioner on claims 33-36, pursuant to 37 C.F.R. § 42.73(b)(4).” Id. (emphases added). Our Rule 42.73(b)(4) concerns “[a]ctions construed to be a request for adverse judgment.” 37 C.F.R. § 42.73(b)(4) (emphasis added). Subsection (b)(4) states one of the actions construed to be a request for adverse judgment is “[a]bandonment of the contest.” Id. The actions construed to be a request for adverse judgment, however, are never reached when a party states unequivocally that it requests “judgment against itself.” that the Request for Adverse Judgement is seeking adverse judgment against itself, not Petitioner. Id. As stated in the title of Patent Owner’s Request for Adverse Judgment, we consider this request under our Rule 42.73(b). As corrected, the Request seeks a “final adverse judgment against [Patent Owner] on claims 33-36,” which are all the challenged claims.

      “Based on our review of the Petition, Petitioner explains that a driving motivation for a POSITA to modify Lundahl to include Larsen’s five panels is “to increase the flexibility of the device to ensure the light panels could be maintained at a distance of 2-4′′ from surface of the treatment area, whether the face, arm, or back, etc.” Pet. 29 (emphasis added). As Lundahl’s device is not flexible, and such flexibility would improve its ability to treat areas other than an average sized face, we determine, at this stage in the proceeding, that this motivation for the combination is sufficient.” slip op. at 20

      “would have been motivated to modify Lundahl’s device by incorporating Larsen’s use of LEDs on the surface of the light applicators in place of Lundahl’s fluorescent tubes with a reasonable expectation of success. Prelim. Resp. 55. Patent Owner argues that Petitioner’s modification is based on improper hindsight bias because “Petitioner cherry-picks Larsen’s LEDs (together with the five panels) and purports to arrange them according to the [sic] ‘the uneven spacing’ of Lundahl’s fluorescent tubes.” Id. at 56 (citing Pet. 46–49; Ex. 1015 ¶¶ 175–80). According to Patent Owner, “Petitioner cannot on the one hand argue that a ‘POSITA would have understood that Larsen’s applicator is configured to uniformly illuminate a treatment surface of the patient,’ while on the other ignore Larsen’s teaching that the ‘light sources 17 are placed in regular row arrangements.’” Id. Patent Owner asserts that Petitioner’s proposed modification “mish-mashes aspects of Lundahl and Larsen ([while] avoiding the overall teachings of [challenged] claims.” Id. at 56–57. As discussed above, based on our consideration of the current record, Petitioner has provided sufficient motivation for employing Larsen’s flexible five panel configuration. These panels in Larsen already use LEDs as their light source. So, in our view, Petitioner’s incorporation of the five panels includes the lighting source, i.e., LEDs, for those panels taught by Larsen. Further, we note that Petitioner has persuasively asserted that a skilled artisan would have been motivated to use Larsen’s LEDs as they are more cost-efficient and last longer.

      “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. Cir. 2019) (“The Board is required to construe ‘only those terms. . . that are in controversy, and only to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am.

      “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.

      “that Petitioner has not shown sufficiently that Shakkarwar teaches the claimed mapping limitation, for the following reasons. The lookup table in Shakkarwar has a list of clock speeds (frequencies) for specific devices. Ex. 1006, 7:7–10. These clock speeds represent the bandwidth needs of each individual device. 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. 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.
