      “institute an inter partes review. 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.” The Supreme Court has held that the Board, in a decision to institute under 35 U.S.C. § 314(b), may not institute review on less than all claims challenged in the petition. SAS Inst. Inc. v. Iancu, 138 S. Ct. 1348, 1355–56 (2018). Moreover, in accordance with our rules, “[w]hen instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a) (2024); see also PGS Geophysical AS v. Iancu, 891 F.3d 1354, 1360 (Fed. Cir. 2018) (interpreting the statute to require “a simple yes-or-no institution choice respecting a petition, embracing all challenges included in the petition”). Applying those standards, and upon considering the Petition, the Preliminary Response, and the evidence of record, we determine the information presented a reasonable likelihood that Petitioner would prevail in establishing the unpatentability of at least one of the challenged claims of the ’639 patent. Accordingly, we institute an inter partes review.” slip op. at 2

      “We find that Petitioner has shown sufficiently on this record that the combination of Fakoorian-1 and Takahashi teaches limitations [1d] and [1e]. See Pet. 21–28. As Petitioner argues, Fakoorian-1 includes multiple SPS configurations and teaches that configuration parameters, related to a first and a second SPS configuration, may be sent to the UE in one or more RRC messages. See Pet. 21, 23–24. These parameters include a “periodicity,” “CS-RNTI,” “HARQ process number,” and “service type.” Id. at 21, 24. Petitioner has also shown sufficiently, based on the testimony of Dr. Mandayam, which at this stage stands unrebutted, that a person of ordinary skill in the art would have understood that a “HARQ process number” is “used to indicate which [SPS] configuration(s) are to be” released, and Fakoorian-1’s UE acknowledges the “release by transmitting the acknowledgement in a codebook through a physical uplink control channel (PUCCH) resource.” Id. at 23. 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. See Ex. 1003 ¶¶ 80–84. Thus, on this record, we find that this testimony is sufficient.” slip op. at 15

      “understanding of a person of ordinary skill in the art at the time of the invention. Graham, 383 U.S. at 17. Valve contends that the ordinarily skilled artisan would have: a bachelor’s degree in an industrial design or engineering field, and approximately two years of relevant experience, for example. Alternatively, the same or an equivalent level of skill in the art could be obtained by end users or hobbyists who have substantial experience modifying or creating customized game controllers that include features to better suit their needs, even without any college education. Pet. 10 (citing Ex. 1009 ¶ 11). Ironburg, without expressly defining the level of ordinary skill, contends that a college degree of the type identified by Valve is not required. See Supp. PO Resp. 4–6. Ironburg notes that the level of ordinary skill is “relatively low” and the technology involved “is simple and straightforward.” Id. at 4 (citing Ex. 2016 ¶ 21).

In IPR2016-00948, in which we addressed similar claim limitations in a related patent, U.S. Patent 8,641,525 (Ex. 1038, the “’525 patent”),12 we found that “thickness” as used in claims such as claims 18 and 19 refers to “the dimension of the elongate member perpendicular to 12 Claims 10 and 11 of the ’525 patent contain the limitations directed to the thickness of the elongate member that substantially parallel the limitations introduced in claims 18 and 19 respectively.

      “2. Whether the Combined Teachings of Burns and LaCelle Describe All Elements of Claims 18, 19, 21, 26, and 29 Valve argues that it is “undisputed that all elements of base claim 1 are taught by the combination of Burns in view of LaCelle.” Valve Remand Br. 21 (citing Pet. 33–38; Ex. 1009 ¶¶ 23–25, 27–29). Ironburg disagrees, responding that “neither Burns nor LaCelle discloses the first control with an elongate member having a second surface arranged to be non-parallel with the back, outer surface of case.” Ironburg Remand Br. 20. Ironburg’s argument appears to rest on the issue of whether LaCelle describes its underside items as a control. We have already found that LaCelle’s underside items are controls as explained above. However, even if LaCelle did not disclose that its underside items were controls, Valve relies upon Burns as describing this aspect of claim 1. Valve Supp. Reply 9–10. Either way, Valve persuades us that the Burns and LaCelle, when combined as Valve suggests, teach every element of claim 1. In Parts II.D.1–4 above, we have also analyzed the parties’ arguments and supporting evidence on the issues of whether Burns describes the limitations introduced in each of claims 18, 19, 21, 26, and 29. For the reasons expressed above, Valve persuades us that Burns and LaCelle, when combined as Valve suggests, teach every element of dependent claims 18, 19, 21, 26, and 29. We have already concluded that Valve has proven that an ordinarily skilled artisan would have been motivated to combine teachings of Burns and LaCelle to arrive at the invention of claim 1, and those motivations also suffice for dependent claims 18, 19, 21, 26, and 29, all of which introduce limitations that we find to be described by Burns. Accordingly, we find that Valve has proven by a preponderance of evidence that the combined teachings of Burns and LaCelle render claims 18, 19, 21, 26, and 29 unpatentable as obvious.” slip op. at 25

      “On the first issue, we find that LaCelle’s underside items would have been understood by an ordinarily skilled artisan as a “control.” LaCelle describes the article illustrated in all its figures as a “game controller.” Ex. 1005, code (57). Dr. Rempel testifies that even if an ordinarily skilled artisan “were not 100% certain that the identified features on the back of the . . . LaCelle . . . controller[] are functional controls, their location and appearance certainly suggests functional back controls to one of ordinary skill in the art (even if another interpretation were also possible).” Ex. 1019 ¶ 12. The Federal Circuit has instructed us that we erred by failing to consider Dr. Rempel’s testimony supporting Valve’s Supplement Reply. Valve II, at 16. Dr. Rempel’s testimony is consistent with the manner in which LaCelle graphically depicts the items on the underside of its game controller, and we credit that testimony as being persuasive. Additionally, as we explain below, we do not find that Valve must prove that LaCelle describes its underside items as a control to support its position that an ordinarily skilled artisan would have been motivated to apply the curved shape of LaCelle’s underside items to the surface of Burns’s elongate members. On the second issue, we find that LaCelle undisputedly describes its items on the underside of the controller as being curved. On the third issue, the probative value of Valve’s Supplemental Reply argument and supporting evidence, the Federal Circuit held that we ignored important testimony establishing that an ordinarily skilled artisan “‘would have combined LaCelle and Burns’ and ‘would recognize that the predictable result of the combination — a back paddle having an end that is curved like that of LaCelle — could have better coupling with the user’s finger.’” Id., at 17–18 (quoting Ex. 1019 ¶ 39 with added emphasis). The Federal Circuit also refocused our obviousness inquiry on “whether a person of ordinary skill in the art would have been motivated to combine Burns and LaCelle, not whether the combination would with absolute certainty result in the desired outcome.” Id. at 18. Dr. Rempel’s testimony cited by the Federal Circuit establishes that an ordinarily skilled artisan would have been motivated to apply the curved shape of LaCelle’s underside items to Burns’s elongate members. Our original Remand Decision failed to consider that testimony, and the Federal Circuit has identified that failure as error. Valve II, at 17. The argument proffered by Ironburg to rebut Dr. Rempel’s testimony is not supported by evidence. See Ironburg Remand Br. 23–24 (citing our Remand Decision but failing to cite evidence in support of Ironburg’s proffered argument).” slip op. at 24

      “We consider the disclosures of the Provisional Application, which refer to cases 1 and 2, in which requests are redirected to an origin server for lower popularity content and to a parent server for medium popularity content at steps 522 and 524 as shown in Figure 5, respectively, wherein the edge server receives a redirect from the popularity service without a “followme” flag. See Ex. 1011 ¶¶ 43, 44. The Provisional Application also discloses that, by comparison, if there is a “follow-me” redirect sent to the edge server, it obtains and caches a resource as shown at step 528 for higher popularity content. Id. ¶ 44. On this record, as Patent Owner asserts, these disclosures are consistent with technical reasons provided in the Provisional Application for instructing the edge server not to cache unpopular resources. See Ex. 1011 ¶¶ 68–69. In light of these disclosures, we preliminarily find support for Dr. Shenoy’s testimony that, even with the words “instruction to not cache” are not literally recited in the Provisional Application, caching and not caching are alternative options that indicate the instruction to the edge server that will be implemented for each option. See Ex. 2014 ¶ 56. Further, these disclosures provide support for Dr. Shenoy’s testimony that the disclosures “reasonably convey to those skilled in the art that Patent Owner had possession of the edge server receiving an instruction to not cache the resource (and instead simply forward the redirect).” Id. In re Johnson states that “it is not true that the factual context out of which the question under § 112 arises is immaterial. Quite the contrary. Here, . . . the ‘written description’ in the [] specification supported the claims in the absence of the limitation, and that specification, having described the whole, necessarily described the part remaining.” See Johnson, 558 F.2d at 1019. This is consistent with M.P.E.P. § 2173.05(i) which states, “[i]f alternative elements are positively recited in the specification, they may be explicitly excluded in the claims.” M.P.E.P. § 2173.05(i). Further, “the failure of the specification to specifically mention a limitation that later appears in the claims is not a fatal one when one skilled in the art would recognize upon reading the specification that the new language reflects what the specification shows has been invented.” All Dental Prodx, LLC v.

Even though we do not discern that the Provisional Application explicitly discloses an “instruction to not cache,” at least on this preliminary record, and for the purposes of this Decision, there is positive recital of instructions to cache in the Provisional Application and Petitioner has provided sufficient supporting evidence that caching and not caching are alternative options. Further, there is sufficient evidence, in the context of the disclosures of written description support in the Provisional Application, providing support for Dr. Shenoy’s testimony that Patent Owner had possession of an edge server receiving an instruction to not cache the resource. Nonetheless, we invite additional briefing on these issues, including issues relating to alternative options of caching and not caching. On this preliminary record, we find that the ’573 patent has a priority date of April 2, 2008, which predates the earliest possible date on which Newton-471 could be effective as prior art, September 30, 2014 (the date on which the earliest application in the priority chain of Newton-471 was filed). Accordingly, we preliminarily find that Newton-471 is not prior art to the challenged claims. Thus, on the present record, Petitioner has not demonstrated a reasonable likelihood that it would prevail in showing that claims 1–20 are anticipated by Newton-471.” slip op. at 13

      “C. Claim Interpretation We interpret each challenged claim using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.100(b). Petitioner argues that “no claim terms need be construed.” Pet. 10. Patent Owner does not propose interpretations of any claim terms in its Preliminary Response.

      “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. Based on the totality of the evidence currently in the record, Petitioner has established a reasonable likelihood that 3GPP-38.213-CR is a prior art printed publication under 35 U.S.C. § 102(a)(1).” slip op. at 20

      “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). As part of these RA procedures, we agree that Cirik discloses sending a configuration message including “one or more random access channel (RACH) parameters.” Id. (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). Cirik explains this “contention-free random access procedure . . . may be initiated for beam failure recovery.” Ex. 1005 ¶ 162; see also Pet. 20–23 (discussing in detail in the context of limitation [1b] the RA procedures for beam failure recovery in Cirik). 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. Prelim. Resp. 4 (“But at no point does Petitioner assert that the configuration message for first random access parameters is included within the ‘one or more configuration parameters [that] indicate the maximum number of beam failures’ that it identifies for the ‘configuration parameters’ limitation.”). Accordingly, for purposes of institution, we find that Petitioner has shown sufficiently that Cirik discloses this limitation.” slip op. at 16
