However, as Patent Owner argues, Petitioner fails to show that the ’298PROV provides support for the specific subject matter relied on in Walker. See Sur-Reply 3–9. Petitioner only explains how the ’298PROV discloses “predetermined criteria” but does not provide any other explanation for how the other subject matter relied on in Walker is supported by the ’298PROV. Thus, we find that Petitioner has failed to show that Walker is entitled a priority date before May 1, 2003.

    “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.

  • Skill levelSkill level board ownDecided for patent owner

    “We agree with Patent Owner’s first argument that a level of ordinary skill in the art that encompasses an individual having experience with electrical circuits but not electrical connectors is not consistent with the technology and descriptions in the ’017 patent. See PO Resp. 7. The field of the invention of the ’017 patent is “electrical connectors, and more particularly, . . . an electrical connector that suppresses arcing if connected or disconnected while current is flowing.” Ex. 1001, 1:7–9. Consistent therewith, the challenged claims are directed to “[a]n electrical connector pair” and recite structural features of the electrical connector pair. Id. at 4:20–56, 5:1–20.” slip op. at 10

    “We find that the intrinsic evidence supports maintaining our construction in the Institution Decision that “insulating” means “electrically insulating.” See Dec. 11–12. In particular, we agree with Patent Owner’s argument that the insulating barriers would be unable to be configured to “block[] substantially all through-air arcing paths between the first and second electrical contacts,” as claimed, unless they were electrically insulating. See Ex. 1001, 4:36–44. Moreover, as Patent Owner avers, our interpretation of “insulating” as it applies to the first and second insulating barriers should be the same as for the first and second housings. See Digital Biometrics, 149 F.3d at 1345 (“whatever interpretation we assign [to a word used in a claim] should encompass both uses because the same word appearing in the same claim should be interpreted consistently” (citation omitted)).” slip op. at 15

    “Id. at 3:27–37 (emphasis added). These wall portions 58 are located between the distal ends of the terminals and where Petitioner proposes to add a printed circuit board or wiring board to Winkler. See id. at Fig. 2; Pet. 44–46 (diagrams showing Winkler as modified to have a printed circuit board or wiring board). As such, movement of Winkler’s terminals appears to be mostly limited to within their respective receiving pockets. Given the above teachings, we fail to see how Petitioner’s proposed modification would have meaningfully interfered with the degree of freedom of movement required by Winkler’s terminals. Notably, Mr. Locati’s testimony regarding this issue is conclusory. See Ex. 2001 ¶ 120. Because movement of Winkler’s terminals occurs primarily in the receiving pockets, we also do not discern how the solder joint of Petitioner’s proposed modification would experience undue stress or risk breaking due to that movement. See Ex. 1004, 1:47–55, 3:14–37, Fig. 2; Pet. 44–46. This is particularly true in view of Winkler’s teaching that each cylindrical end portion may be soldered to a cable. See id. at 2:6–10; see also Pet. 43 (arguing that Winkler teaches soldering to a cable but not specifically to a printed circuit or wiring board). Accordingly, we determine that Petitioner has shown by a preponderance of the evidence that claim 8 would have been obvious over the combined teachings of Winkler and Handbook.” slip op. at 55

    “We find the District Court’s reasoning persuasive, and we, like the District Court, decline to adopt Petitioner’s overly broad proposed construction. However, for purposes of deciding the dispositive fact issue before us, we need not determine the precise boundaries of “surrounding textile structure,” for example whether it completely or mostly encircles the textile element, and if “mostly,” what percentage of encircling is required. See Pet.

We find that a person of ordinary skill in the art would not understand the portion of Zuckerman’s strip 13 in purple to surround the green blank 11 (textile element) under any reasonable construction of “surrounding textile structure.” Dr. Pastore testifies that “Zuckerman discloses two separate textile structures adjacent the blank—one on each side . . . they abut only two sides of Zuckerman’s blank, with each structure abutting only about a quarter of the blank’s periphery,” and opines that “a POSITA would not have understood these two separate structures, designated by purple in the figure above, to be a textile structure ‘surrounding’ the blank [shown in green].” Ex. 2003 ¶ 54.

    “We agree with Patent Owner that the recited second type SIBs exclude first type SIBs. The plain meaning of “first type” and “second type” indicates that the first type and second type are different in kind. RMTA 22 (App. A). Our interpretation is consistent with the Specification, which explains that second type SIBs exclude first type SIBs. As Patent Owner points out, the ’958 patent discloses “first type of system information (1TYP SIB) is . . . essential . . . for initial system access” and “second type of system information (2TYP SIB) is nonessential system information . . . defined as all other types of information, and thus excludes the [] information required for initial access.” Id. at 11–12 (citing Ex. 1001, 8:34– 46); see also Ex. 1001, Abstract (interchangeably using the terms second type and non-essential). Despite Petitioner’s argument that this disclosure is non-limiting and directed to a disclaimed example embodiment (Opp. 8–9), Petitioner could not identify any embodiment, among the approximately forty disclosed embodiments, describing something other than the first type SIB being essential information and the second type SIB being non-essential information. Tr. 22:18–26. Even the Petition acknowledges that “the ’958 Patent further classifies a second type of system information, the ‘non-essential’ SI, which is defined as all other types of information excluding that first type of information required for initial access.” Pet. 5. Furthermore, the prior art of record suggests that a person of ordinary skill would have understood second type SIBs exclude first type SIBs. See Ex. 1008 ¶ 48 (describing two categories of system information, “essential SI” and “Other SI”). Patent Owner’s expert also understood the recited first and second type SIBs as being mutually exclusive. See Ex. 1011, 49:10–13. For the above reasons, we do not agree with Petitioner that the recited second type SIB lacks any requirements, nor do we interpret claims 7 and 8 such that the first type SIB could be a second type SIB.” slip op. at 19

    “(d) Limitation 7h: Analysis We agree with Patent Owner that Petitioner’s arguments with respect to limitation 7h are insufficient because they fail to address the limitation as written and improperly incorporate previous arguments by reference. For example, Petitioner did not map the recited “group identifier” when opposing Patent Owner’s Revised Motion to Amend. See Opp. 16–17.

Petitioner similarly failed to address adequately where Lee discloses or suggests the recited “compressed format” and “plural parameters.” See Opp. 16–17. Aside from the above concerns, we also do not see sufficient explanation with respect to limitation 7h’s requirement that the transmitting by broadcast be based on a comparison of the value tag. Petitioner argues that, because Patent Owner does not dispute limitation 7g, “it would have been obvious to a POSITA to use the same value tag[] to determine the system information broadcast in Lee’s compressed format embodiment.” Pet. Sur-reply 12. This conclusory statement is not supported by any citations to evidence and was improperly introduced in the Sur-reply. Moreover, whether it was obvious to determine what system information is broadcast is not commensurate with the claim scope because limitation 7h requires that the broadcasting (not the broadcast content) be based on a comparison of the value tag.
