      “prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed. Cir. 2001) (holding that absent evidence to the contrary, “the prior art itself [may] reflect[] an appropriate level” of ordinary skill in the art). In general, we agree with the areas of agreement in the parties’ proposals. In particular, Patent Owner proposes “at least a Bachelors’ degree in a field of engineering or physics,” which includes “electrical engineering or a comparable field of study” as Petitioner proposes. Pet. 4 (emphasis added); PO Resp. 10. We agree with Petitioner that by defining the engineering field as “electrical” or “comparable,” we can exclude engineering fields “having nothing to do with displays, such as biomedical, civil, chemical or environmental engineering.” Pet. Reply 1. Petitioner also proposes approximately “one or more years of professional experience” which includes Patent Owner’s “at least two years of professional experience.” Pet. 4; PO Resp. 10. Furthermore, both parties agree that “[a]dditional graduate education could [reduce . . . the time requirement] for professional experience.” Id. Thus, we adopt both parties’ proposed POSITA of having a Bachelors’ degree in electrical engineering or a comparable field of study, plus at least two years of professional experience, wherein additional graduate education could reduce the time requirement for professional experience. Id. Such proposal comports with the level of ordinary skill in the art reflected in the prior art of record.” slip op. at 10

      “The plain language in claim 1 of “auxiliary electrode” does not preclude that the “electrode” may be a power line, bus line, or resistor. Ex. 1001, 8:47–52. Nothing in the Specification clearly precludes “auxiliary electrode” from being a “bus line” or “power line,” as Patent Owner proposes. PO Resp. 25–27. We are unpersuaded by Patent Owner’s contention that the Specification discloses that “the power line ‘PL’ is shown in Figure 1, but the power line PL is not an electrode that is shown in Figure 2.” Id. at 26–27. Here, Patent Owner points to no portions in the Specification that provide the requisite “reasonable clarity, deliberateness, and precision” to warrant interpreting the claim language at issue as supporting Patent Owner’s contention that an auxiliary electrode cannot be a power line, bus line, or resistor. Id.; In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1984). That is, although Patent Owner points to Figures 1 and 2 of the Specification for support of its contention, Figures 1 and 2 of the Specification merely show various examples of power line and an auxiliary electrode. PO Resp. 26–27. Thus, although the referenced portions of the Specification discuss various examples wherein an auxiliary electrode may be implemented, nothing in these referenced portions of the Specification clearly precludes the “auxiliary electrode” from being a power line or any electrode that is “the road to get to an end point,” as Patent Owner contends. Id. Patent Owner points to no special definition, implicit or explicit, for “auxiliary electrode” that is set forth in the Specification which supports Patent Owner’s construction with reasonable clarity, deliberateness, and precision.

      “We find Patent Owner’s arguments unavailing. In particular, we find unavailing Patent Owner’s contention that “‘bus line 430’ is not an ‘auxiliary electrode’” (PO Resp. 28–33), because Patent Owner is relying on a claim construction of “auxiliary electrode” as precluding “essential” elements and requiring “more than the end structure of a conductor” (id.), that is not adopted by our construction discussed above. Here, we are persuaded by Petitioner’s reliance on Weaver’s bus line 430 for providing the claimed “electrode,” that is “supplemental to other electrodes in the structure.” Pet. 18; see also Ex. 1004 ¶ 26, Fig. 4; Ex. 1003 ¶ 92. We find availing Petitioner’s contention, supported by Dr. Baker’s testimony, that a POSITA would have understood that “anode 406 and bus line 430 are connected in parallel,” which means that “bus line 430 is a supplemental electrode that reduces the total resistance of the pixel structure.” Pet. 19; Ex. 1003 ¶ 94. Thus, we find availing Petitioner’s contention, supported by Dr. Baker’s testimony, that Weaver’s bus line 430 is an electrode supplemental to other electrodes in the structure that is electrically insulated from transistor 410 by passivation layer 409, wherein OLED 400, which includes cathode 422, organic layer 424, and anode 406, is disposed above bus line 430, and wherein anode 406 of OLED 400 is electrically connected to bus line 430 by via 428. Pet. 16–19; Ex. 1003 ¶¶ 89–94. That is, we find availing Petitioner’s contention that, like the ’509 patent’s auxiliary electrode 120, bus line 430 is electrically insulated from transistor 410, wherein OLED 400 is disposed above bus line 430 and anode 406 electrically connected with bus line 430.

      “We also find unavailing Patent Owner’s contention that the proposed modifications to Weaver would involve changing the process. PO Resp. 33– 34. We agree with Petitioner, whose contentions are supported by Dr. Baker’s testimony, that “to provide additional components from the same layer is a layout change that a POSITA would have been able to perform without changing the process.” Pet. Reply 17–18 (citing Ex 1003 ¶ 157; Ex. 1020 ¶ 45). Further, contrary to Patent Owner’s contention that POSITA would not have combined Weaver with Lee ’053, Song, Lee ’149, or Bae without the use of hindsight (PO Resp. 33–45), as Petitioner points out, Lee ’149, for example, “explicitly teaches that ‘the electrode pattern 45 serves to lower the resistance of the first electrode 41.” Pet. Reply 58 (citing Ex. 1011 ¶ 38). Similarly, Bae “explicitly teaches that the “auxiliary electrodes 139 contact the first electrode 132 to commonly apply a voltage to the sub-pixels” and “reduces the resistance of the first electrode.” Id. at 66 (citing Ex. 1012 ¶¶ 37, 59). As such, Petitioner’s proposed combinations are supported by at least by Lee ’149’s and Bae’s teachings of applying a second electrode to lower the resistance and voltage drop between anode 406 and the VDD line of Weaver. See, e.g., Ex. 1011 ¶ 38; Ex. 1012 ¶¶ 37, 59. We are persuaded by Dr. Baker’s testimony that a POSITA would have understood that higher resistance between the power or ground line to the light emitting device would consume more power and require higher operating voltages, and thus, would have been motivated to implement the solutions of Lee ’053, Song, Lee ’149, or Bae to lower the resistance between anode 406 and voltage source VDD in Weaver. Ex. 1003 ¶¶ 145, 158, 184, 203. We agree with Petitioner, supported by Dr. Baker’s testimony, that a POSITA would have had a reasonable expectation of success the combining the references as suggested, wherein such modification “involves modifications of only routine skill in the art,” which “involve known method,” and “would have yielded predictable results. Pet. 42, 48–49, 59, 67–68; Ex. 1003 ¶¶ 145, 158, 184, 203. That is, we determine that Petitioner has set forth reasoning with rational underpinning explaining why it would have been obvious to combine the teachings with a reasonable expectation of success. Based on the complete record presented, we determine Petitioner has shown by a preponderance of the evidence that claims 6–8 would have been obvious over the combination of Weaver and Lee ’053 or alternatively over the combination of Weaver and Song, and that claims 10 and 11 would have been obvious over the combination of Weaver and Lee ’149 or alternatively over the combination of Weaver and Bae.” slip op. at 33

      “petition identifies all real parties in interest. 35 U.S.C. § 312(a)(2). Whether an unnamed party is a real party in interest “is a highly fact-dependent question.” See Applications in Internet Time, LLC v. RPX Corp., 897 F.3d 1336, 1351, 1360 (Fed. Cir. 2018) (“AIT”); Ventex Co., Ltd. v. Columbia Sportswear N. Am., Inc., IPR2017-00651, Paper 152 at 4–5 (PTAB Jan. 24, 2019) (precedential) (citing Worlds Inc. v.

Other considerations include whether the non-party is funding or directing the proceeding; the non-party’s relationship with the petitioner; the non-party’s relationship to the petition itself, including the nature and/or degree of involvement in the filing; and the nature of the entity filing the petition.

      “person of ordinary skill in the art (“POSITA”) “would have at least a bachelor’s degree in electrical engineering or a related field and at least two years of experience with lighting technology.” Pet. 2 (citing Ex. 1017 ¶ 35). Petitioner makes additional contentions about what a POSITA would have understood. Id. (“A POSITA would understand that all types of cameras (e.g., analog and digital, photo and video) generally involve the same lighting considerations . . . . [and] that it is important to provide light that evenly illuminates the target subject or object to minimize reflected glare and shadows.”). Patent Owner contends that a POSITA would have at least: (a) a bachelor’s degree in electrical engineering, optical engineering, or a related field; (b) two years of practical experience in designing and developing lighting systems, particularly those integrated with electronic devices such as webcams or computer monitors; and (c) knowledge of user-interface considerations for consumer electronics . . . . Additional experience can substitute for education and vice versa. Prelim. Resp. 12 (citing Ex. 2036 ¶ 48). Patent Owner disputes Petitioner’s contentions regarding what a POSITA would have understood. Prelim. Resp. 12–13 (“[O]ne of ordinary skill in the art would have understood that analog and digital cameras have different operating principles and lighting requirements [and] Petitioner’s lack of appreciation for the suitability and unsuitability of different lights for different applications infects and dooms its invalidity analysis.” (citing Ex. 2036 ¶¶ 36–47)). and years of experience required for a POSITA. Pet. 2; Prelim. Resp. 12. For purposes of this Decision, we consider a person of ordinary skill in the art to have a bachelor’s degree in electrical engineering or related field and two years of practical experience in lighting technology, and that additional experience may substitute for education and vice versa, which is consistent with the level of skill reflected in the ’729 patent and prior art of record. See Exs. 1001, 1005–1010, 1012–1015; see also Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

As Dr. Mandayam testifies, a person of ordinary skill in the art would have understood, based on Fakoorian-1, that a HARQ process number indicates an identifier for the HARQ codebook to be used by the UE to transmit the acknowledgment. Id. (citing Ex. 1003 ¶ 84). Dr. Mandayam provides sufficient reasoning, at this stage, to support his opinion, so we do not agree with Patent Owner that this testimony is conclusory.

      “Assessing the evidence of record collectively, however, we are persuaded that Petitioner has shown a reasonable likelihood that 3GPP-38.213-CR was publicly accessible from the ETSI email archive before November 5, 2019. Given his many years of experience with ETSI, in particular his responsibilities pertaining to management of documents like change requests, and as the “list owner” “responsible for managing and administrating” several email exploder lists, Mr. Rodermund appears to be well-qualified to testify to the matters in his declaration. See Ex. 1008 ¶¶ 7, 10–15, 49. He explains in detail how, based on his experience, emails sent to a 3GPP email exploder were accessible on the email archive immediately after being sent. Id. ¶¶ 44–60, 72–80. That explanation is supported by screenshots from various websites and other corroborating evidence. See Ex. 1008 ¶¶ 44–60, 72–80. The November 3, 2019, email with 3GPP-38.213-CR as an attachment is currently available to the public via the email archive, with no login, password, or membership required to access it. Id. ¶¶ 44, 74; see Kyocera, 545 F.3d at 1351 (“[ETSI] specifications themselves were visible to any member of the interested public without requesting them from an ETSI member. Further, ETSI did not impose restrictions on ETSI members to prevent them from disseminating information about the standard to non-members.”). The metadata for the file indicates that it was created and last modified one day before the email was sent. Ex. 1008 ¶ 76. And Mr. Rodermund discusses one example where a listserv email was uploaded to the archive just minutes after being sent. Id. ¶¶ 50–51. Although that example is from 2025 rather than 2019, it provides some support for his opinion that the same “near contemporaneous” timing would have been the case in 2019 as well. See id. ¶ 52. Immediately making emails like the one with the 3GPP-38.213-CR change request available on the email archive is consistent with 3GPP’s overall purpose of making standards documents available “so that engineers and other individuals would have ready access to them when developing and implementing cellular networks and devices.” See id. ¶ 35; Kyocera, 545 F.3d at 1351 (finding that the “primary purpose of the [standard at issue] was to develop a system interoperable across national borders,” which “made it crucial to grant access to any interested parties”); Cradlepoint, Inc. v. Sisvel Int’l S.A., IPR2020-01103, Paper 46 at 13–14 (PTAB Jan. 18, 2022) (finding, based on the preponderance of the evidence, that “testimony concerning [a 3GPP] email exploder and listserv provide further support for a conclusion of public accessibility because it tends to show that 3GPP was known beyond its members, that the meetings were widely publicized, and that 3GPP documents were, in general, widely available”). Finally, Mr. Rodermund explains in detail how a person of ordinary skill in the art could have accessed the email with 3GPP-38.213-CR, using the indexing of the email archive. See Ex. 1008 ¶¶ 49, 53–60. We are persuaded that Mr. Rodermund’s testimony and supporting evidence are sufficient at this stage. Patent Owner will have the opportunity to cross-examine Mr. Rodermund and explore the bases for his statements. And our ultimate determination of the weight to be given to his testimony will be based on the complete record at the end of trial.

      “On the current record, we find that Petitioner has shown sufficiently that Cirik teaches the claimed “configuration parameters comprising first random access parameters, for beam failure recovery.” See Pet. 13– 17. Patent Owner argues that Petitioner fails to address this limitation, but we disagree. Prelim. Resp. 3. As we have set out above, Petitioner has provided a detailed mapping of what disclosures of Cirik (and Cirik’s provisional) on which it relies. Based on the current record, we see nothing incorrect in Petitioner identifying multiple parameters as making up the “configuration parameters comprising first random access parameters, for beam failure recovery.” As the plain language of claim 1 makes clear, there are “parameters”—plural—not just one. We also find, on the current record, that those “parameters” are not limited by the claim to only “random access parameters.” The disputed claim limitation uses the transitional phrase “comprising” in reciting the “configuration parameters comprising first random access parameters, for beam failure recovery.” As courts have explained, “[i]n the parlance of patent law, the transition ‘comprising’ creates a presumption that the recited elements are only a part of the device, that the claim does not exclude additional, unrecited elements.” Crystal Semiconductor Corp. v. TriTech Microelectronics Int’l, Inc., 246 F.3d 1336, 1348 (Fed. Cir. 2001). Claim 1 recites “configuration parameters comprising first random access parameters, for beam failure recovery.” Thus, we agree with Petitioner that the “configuration parameters comprising first random access parameters, for beam failure recovery,” can—but are not required to—include additional parameters (i.e., in addition to the recited “first random access parameters”). Here, we find that, on the current record, Petitioner has shown sufficiently Cirik’s “configuration parameters [that] may indicate the maximum number of beam of beam failure counter” are such parameters for beam failure recovery. Ex. 1005 ¶ 307; Ex. 1003 ¶ 52. As the Petition’s citations suggest, these are substantially the same as examples identified in the ’615 patent. See Pet. 15–16 (citing Ex. 1001, 63:18–23, 41:65–67; Ex. 1003 ¶ 56). Petitioner has further sufficiently shown that Cirik also discloses that as part of its beam failure recovery process, Cirik initiates certain “random access (RA) procedures.” Id. at 16 (citing Ex. 1005 ¶ 152, 161–164, Figs. 13A–C).

(citing Ex. 1005 ¶¶ 151–154, 156, 161; Ex. 1003 ¶ 57). As Petitioner explains, “[t]he RACH parameters included in a configuration message can include indications of ‘one or more Physical RACH (PRACH) occasions available for transmission’ of a random-access preamble message and information for determining the power level of the transmission.” Id. (citing Ex. 1005 ¶¶ 153, 154).

We note that nothing in the claim language requires that the configuration parameters must be received in a single message. Thus, there is nothing improper about the Petitioner identifying multiple messages as including the “configuration parameters, comprising first random access parameters, for beam failure recovery” (i.e., Cirik’s configuration parameters that indicate the maximum number of beam failures and Cirik’s configuration parameters for random access processes used in connection with beam failure recovery), as Patent Owner suggests.

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “B. Level of Ordinary Skill in the Art Petitioner argues that at the time of the ’695 patent (November 2019),4 a person of ordinary skill in the art would have had “a bachelor’s degree in electrical engineering, computer engineering, computer science, or a similar field, along with two years of experience designing or developing wireless networks, including long-term evolution LTE/4G or 5G new radio (NR) cellular technology,” where “[a]dditional years of experience could substitute for an advanced-level degree (and vice versa).” Pet. 6 (citing Ex. 1003 ¶¶ 29–32). Patent Owner “utilizes Petitioner’s proposed level of skill in the art” for its Preliminary Response. Prelim. Resp. 2. Based on the record presented, including our review of the ’695 patent and the types of problems and solutions described in the ’695 patent and cited prior art, we agree with Petitioner’s proposed definition of the level of ordinary skill in the art and apply it for purposes of this Decision.” slip op. at 10

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundInstituted

      “3. Claim 1 a) Petitioner’s Contentions Petitioner argues that Ying and Yang collectively teach all of the limitations of claim 1 and a person of ordinary skill in the art would have been motivated to combine their teachings, with a reasonable expectation of success. Pet. 11–28. As to the combination of references, Petitioner asserts that a person of ordinary skill in the art “would have been motivated to include configuration parameters for both the NUL and SUL carriers, as taught in Ying, in a single DCI, as expressly depicted in Yang, to coordinate both normal uplink (NUL) and supplemental uplink (SUL) transmissions in a mobile communication environment.” Id. at 12 (citing Ex. 1003 ¶¶ 58–59). According to Petitioner, “[t]he combination involves coordinating both carriers already operating in the mobile communication environment by implementing Ying’s DCI example (e.g., in Listing 6) to provide cancellation indications for both the normal uplink (NUL) and the SUL in one DCI,” achieving the “predictable result” of “improv[ed] communication capacity, speed, flexibility, and/or efficiency.” Id. at 12–13 (quoting Ex. 1004, col. 1, ll. 31–41). Petitioner also alleges various other reasons for why a person of ordinary skill in the art would have been motivated to combine the references’ teachings in that manner, including “reduced communication overhead,” simplification of the UE’s decoder operation, and the need to choose from only two options (i.e., “using one DCI to encode both NUL and SUL carriers . . . or using two DCIs”). Id. at 13–17 (citing Ex. 1003 ¶¶ 60–64).” slip op. at 15
