      “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. We conclude that no express interpretation of any claim term is necessary to determine whether to institute an inter partes review in this proceeding, but encourage the parties to address various claim interpretation issues identified below during trial. See infra Section II.D.5; Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“Because we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy,’ we need not construe [a particular claim limitation] where the construction is not ‘material to the . . . dispute.’” (emphasis added) (citation omitted)).” slip op. at 11

      “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

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.

Moreover, a finding of anticipation resting upon a reference’s disclosures of elements in different embodiments turns on whether an ordinarily skilled artisan would understand that the reference suggests arranging the elements of the embodiments to one another in the same way as the challenged claims. For the reasons that follow, we determine that there is sufficient description and teaching in Kim such that the “combined button” disclosed by Kim, for example in Figure 10(b), can be the same “combined button” as discussed in the embodiment of Figure 18.” slip op. at 28

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

      “As to Patent Owner’s first and second arguments, as we discussed in detail above with respect to anticipation, we find that there is sufficient evidence in Kim itself of contextual and even express links between the various combined button embodiments and Figure 18. Section II.D.2.b)(1)– (4). We have already determined “that one of ordinary skill in the art would understand Kim to disclose the ‘combined button’ structure and function that could be implemented on the face or sidewall of a device.” Id. We likewise determine, based on the same evidence, that a person of ordinary skill in the art would have understood Kim to suggest that the combined button structure and function, for example in the embodiment of Figure 10(b), could be implemented in an opening on the face or sidewall of a device. Obviousness does not require an instruction manual on how to physically incorporate or combine the disclosures of two embodiments in a reference. As KSR informs us, “in many cases a person of ordinary skill will be able to fit the teachings of multiple patents together like pieces of a puzzle.” KSR, 550 U.S. at 420. Moreover, in this case we have only one prior art patent, Kim, so at least the pieces of the puzzle are all in the same box. The persuasive testimony of Dr. Berger that “a person of ordinary skill in the art would have been familiar with electronic devices with sealed and/or insulated button assemblies, and would understand that those assemblies were not limited to the front face of a device,” is unrebutted in this case. Ex. 1003 ¶ 110. “A person of ordinary skill is also a person of ordinary creativity, not an automaton.” KSR, 550 U.S. at 421. Given the background knowledge of a person of ordinary skill in the art in conjunction with the motivation and teachings in Kim itself for placing sufficient motivation to support the combination of Kim’s Figure 10(b) embodiment with the sidewall placement of the combined button taught in Figure 18 for obviousness purposes. It is well-settled that a single prior art obviousness reference itself can provide motivation for the combination. See General Elec. Co. v. Raytheon Techs. Corp., 983 F.3d 1334, 1352 (Fed. Cir. 2020) (Reversing the Board’s finding of nonobviousness over a single prior art reference, the Court explained that “the Board’s approach would require a motivation to combine each element of the claim—even those present together in a reference. This analysis unduly dissects prior art references into collections of individual elements, requiring a party showing obviousness to re-do the work already done in the prior art reference.”). Patent Owner’s third argument is unavailing because although Dr. Anthony testifies that “implementing the fingerprint sensor assembly of Kim’s Figure 10 embodiment in the ‘lateral surface’ of Kim’s Figure 18 embodiment would have complicated the manufacturing process for the resulting mobile device,” Dr. Anthony does not provide testimony or evidence that implementing the combined button on the sidewall would have been difficult or beyond the level of ordinary skill in the art. Ex. 2009 ¶ 73. We credit Dr. Berger who explains persuasively that “[p]rior to the ’619 patent’s earliest alleged priority date of June 19, 2017, a person of ordinary skill in the art would have known that a mobile electronic device could include one or more button assemblies in a sidewall.” Ex. 1003 ¶ 47 (citing Ex. 1013, 4:40, 19:42–20:4, Figs. 13B, 17, 19A, 19B). It is well-settled that a person of ordinary skill can use his or her ordinary skill, creativity, and common sense to make the necessary adjustments and further modifications to result in a properly functioning device. See KSR, 550 U.S. at 418 (“the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.”).” slip op. at 43

      “At this juncture, we preliminarily agree with Patent Owner’s proffered claim construction. 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)). Although “a patent’s written description can set forth more than one definition of a claim term,” we do not discern that to be the case here. See Pitney Bowes, 182 F.3d at 1310. The portions of the Specification of the ’017 patent that Patent Owner cites use “insulating” and its associated tenses to mean suppressing electrical arcing and protecting from electrical burns, i.e., electrically insulating. See, e.g., Ex. 1001, code (57), 1:58–2:3, 2:42–44, 3:2–6, 3:30–40, 3:63–4:10, cited in Prelim. Resp. 12–14.

      “first and second blade members towards the extended positions.” Ex. 1001, 6:40–41. For this claim limitation, Bowmar relies on Vandewater’s disclosure of “a retaining mechanism . . . such as a biasing element with a ball bearing or a spring wheel” that is used to “retain the blades in a centered position when in their deployed position.” Pet. 45 (citing Ex. 1003, 7:55–8:2). Bowmar also provides supporting testimony from its expert to show how one of ordinary skill in the art would have understood Vandewater’s teaching of the biasing element in conjunction with the blade members depicted in Figure 16. See id. at 46. Futtere responds by acknowledging Bowmar’s reference to “a generic paragraph in Vandewater in which a biasing member is discussed to deploy the blade members.” Prelim. Resp. 19 (emphasis added). Nonetheless, Futtere disputes Vandewater’s so-called “generic” disclosure because “Vandewater fails to provide any enablement of such an idea as the text fails to clarify and the figures . . . fail to disclose such an embodiment.” Id. We reject Futtere’s reasoning, as it amounts to conclusory attorney argument lacking in meaningful evidentiary support. On the other hand, Bowmar provides unrebutted expert testimony to support finding that Vandewater’s biasing member is part of the embodiments of Figures 7–10 and Figures 15–20 relied upon by Bowmar and that such biasing member is used “to deploy the blade members,” as admitted by Futtere. Thus, in the absence of rebuttal evidence from Futtere, we find that Bowmar adequately explains how Vandewater’s biasing element biases the blade members to a deployed, i.e., extended, position, thereby satisfying the “biasing” limitation of claim 11. c. Conclusion For at least the foregoing reasons, Bowmar demonstrates a reasonable likelihood of prevailing in showing that at least independent claim 11 is anticipated by Vandewater.” slip op. at 13

      “Bowmar does appear to dispute Futtere’s proposed construction of “blade member,” asserting that the plain and ordinary meaning of the term does not require that it have a sharp edge, as proposed by Futtere. See Pet. 49. As discussed below, the challenge on which we institute indisputably includes a “blade member” under Futtere’s proposed construction. Thus, we do not need to provide an express construction of “blade member” at this stage. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

      “We disagree with Futtere’s assertions. At the outset, we note that the claims merely require that the pivotal connection be located at the “forward end” of the blade members, not their forwardmost end. Vandewater’s Figures 7 and 10 clearly depict pivot connection 216 at the forward end of blade members 212 and 213. Under no circumstances do we discern how one skilled in the art would view those figures as depicting the pivot connection at a midpoint of the blades, as Futtere contends. And, without question, Bowmar relies on the embodiment of arrowhead 210, as shown in Figures 7–11, by referencing Vandewater’s disclosure of “[t]he pivot connection between blades 212 and 213 and body 214.” Pet. 39 (citing Ex. 1003, 7:33–39, Figs. 7–11). Moreover, Bowmar notes Vandewater’s disclosure that similar components of arrowhead 210 (the embodiment in Figures 7–11) may be applied to arrowhead 310 (the embodiment in Figures 15–20). See id. at 40 (citing 8:49–52). With that in mind, we find that Vandewater clearly contemplates embodiments of the arrowhead wherein a pivotal connection is located at the forward end of the blade members. See Blue Calypso, LLC v. Groupon, Inc., 815 F.3d 1331, 1343–44 (Fed. Cir. 2016) (holding that, although the anticipating prior art reference did not describe a specific example of a computer program that used two differently described functions, i.e., tools, together, “[the reference] did contemplate combining the disclosed functionalities.”). Futtere’s failure to address Vandewater’s express teaching of locating the pivot connection at the forward end of the blade members is fatal to its argument.” slip op. at 9

Pet. 24, 74–75. Obviousness is not determined from the perspective of the inventors or authors of a single prior art reference. Rather, obviousness is determined from the perspective of a hypothetical person having ordinary skill in the art. It is only that hypothetical person who is presumed to be aware of all pertinent prior art. Standard Oil Co. v. American Cyanamid Co., 774 F.2d 448, 454 (Fed. Cir. 1985). Petitioner argues, for instance, that Butt teaches the fire safety aspects of “a controller for interrupting a supply of electricity to an appliance upon detection of a trigger, such as [s]moke.” Pet. 24 (quoting Ex. 1015, 1:16– 18). Dr. Horenstein testifies that from a safety perspective, a person of ordinary skill in the art would have “combine[d] the additional kitchen-safety appliance features of Butt with the Emma microwave/refrigerator so as to enable the Emma microwave to shut down upon the detection of smoke, and to reenable the Emma microwave for a further cooking session when the smoke had cleared.” Ex. 1023 ¶ 124. Where Butt arguably discloses a smoke detector external to an appliance, Dr. Horenstein testifies that a person of ordinary skill in the art would have looked to “Smith to include the smoke sensor in operative connection with the microwave oven with the reset functionality disclosed by Butt for the added benefit of reusing the microwave oven.” Id. ¶ 127 (emphasis added). each directed towards shutting down a component of the device in response to a sensor output indicative of an unwanted condition.” Id. ¶ 127.

Dr. Horenstein explains that inclusion of Butt’s reset functionality with Smith’s smoke sensor operatively connected with the cooking area into Emma would result in such elements merely performing the same function as they do separately, i.e., sensing smoke to withdraw electrical power from an electrical cooking appliance and then re-enabling the electrical cooking appliance. Id. Moreover, Dr. Horenstein testifies that the prior art, for example, Butt, specifically recognized the need to solve the problem of fires in the home started by cooking appliances. Id. ¶ 128 (citing Ex. 1015, 1:22–44). Butt explains, that “[h]ome fires are a serious problem in the United States. The National Fire Protection Association reports that between the years 1999- 2002, for example, there were 114,000 reported home fires associated with cooking alone.” Ex. 1015, 122–25.
