    “B. Level of Ordinary Skill in the Art Petitioner contends that a person of ordinary skill in the art, at the time of the effective filing date of the ’626 patent, “would have had an education background of, or practical experience providing an equivalent to, a Bachelor of Science in Mechanical Engineering, Structural Engineering or a related/equivalent field and at least four years of work experience in construction connector design/development.” Pet. 11 (citing Ex. 1003 ¶¶ 12–15). Patent Owner does not dispute this assessment. PO Resp. 17–18. In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (citation omitted). The level of ordinary skill in the art also may be reflected by the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Neither party argues that the outcome of these cases would differ based on our adoption of any particular definition of the level of ordinary skill in the art. Considering the subject matter of the ’626 patent, the background technical field, the prior art, and Petitioner’s proposed and undisputed definition of the skilled artisan, we apply the level of skill set forth above, which is consistent with the testimony of Mr. Fennell (Ex. 1003 ¶¶ 12–15).” slip op. at 20

    “shaped portion configured to receive the structural component,” “a connection portion,” and “an extension portion,” and that “the extension portion spac[es] the channel-shaped portion from the [connection portion]” and “the channel-shaped portion, the extension portion and the connection portion are rigidly fixed with respect to one another.” Ex. 1001, 12:14–36 (emphases added). Claim 1’s repeated use of “portion[s]” to delineate between the three main elements of the hanger, i.e., channel-shaped portion, connection portion, and extension portion, shows or at least strongly suggests substantial flexibility as to the specific location where one “portion” transitions to another “portion” in the fire wall hanger. Similarly, although claim 1 recites that the “channel-shaped portion” is “configured to receive the structural component,” claim 1 recites no limitation precluding other “portions” of the hanger from also “receiv[ing]” or otherwise contacting the structural component. Patent Owner argues that “channel-shaped portion” should be construed to mean “[the] portion of the hanger that forms a channel configured to receive the structural component.” PO Resp. 19. Petitioner and its expert, Mr. Fennell, agree with this meaning (Pet. Reply 4; Ex. 1046 ¶¶ 16–20), and so do we. Indeed, claim 1 plainly recites this as discussed above. But Patent Owner then urges us to narrow the meaning of “portion” itself such that “channel-shaped portion” requires “all portions of the hanger which directly bound the channel that receives the structural component.” PO Resp. 19 (emphases added). Patent Owner argues the Specification makes this “clear.” Id. (citing Ex. 1001, 2:28–31). Contrary to Patent Owner’s arguments (PO Resp. 19), we find no support in claim 1 to further narrow the interpretation of “portion” in “channel-shaped portion” to mean every portion of the hanger which directly bounds the channel that receives the structural component. See Ex. 1001, 12:14–36 (claim 1). We, like Petitioner, similarly find no support in the Specification or limited prosecution history (see Pet. 5–6), and Patent Owner does not direct us to any, showing that the inventor acted as its own lexicographer or disavowed any claim scope to allot this narrowed interpretation to the subject limitation. See Pet.

    “Petitioner argues, inter alia, that Yamaguchi teaches a joist hanger with an extension portion defining a space between its back flange and channel-shaped portion, and Bundy teaches to size a space created by an extension portion of its joist hanger to receive two layers of ⅝-inch-thick drywall between its back flange plane and channel-shaped portion. Pet. 16–18 (citing 1003 ¶¶ 75–78; Ex. 1007, 5:16–18, Fig. 1; Ex. 1041 (“Perspective View”; “Usage View”)); see id. at 17–18 (discussing “advantages” of two layers of 5/8" drywall as “fire resistance in a fire separation wall”). Petitioner argues the skilled artisan “would have been motivated to receive drywall between Yamaguchi’s back flange and channel-shaped portion to provide a shielded fire resistant wooden frame wall.” Pet. 18 (citing Ex. 1003 ¶¶ 78–79; Ex. 1007, 2:10–24); see id.

Petitioner concludes: This modification to Yamaguchi would have been nothing more than applying a known technique (Bundy’s spacing a hanger seat from a wall frame by distance sufficient to accommodate two 5/8”-thick-drywall sheets for fire resistance) to a similar device (Yamaguchi’s hanger having a spacing of indeterminate length) to obtain the predictable result of a firewall hanger having a space between its channel-shaped portion and a wall frame large enough for receiving drywall therebetween, thereby “protect[ing] the structural members of a building.” Pet. 18 (citing Ex. 1007, 5:18–20; Ex. 1003 ¶ 80). Petitioner argues the skilled artisan would have had a reasonable expectation of success in modifying Yamaguchi as discussed above, “because doing so would still allow Yamaguchi’s hanger to perform its intended function of securing a joist to a wall.” Pet. 18 (citing Ex. 1041, 1; Ex. 1003 ¶ 81). Petitioner argues, “[r]ecognizing that Yamaguchi’s and Bundy’s hangers are constructed from sheet metal,” the skilled artisan “would have understood how to modify the size of Yamaguchi’s extension portions to accommodate two layers of 5/8”-thick-drywall while still allowing Yamaguchi’s hanger to secure a joist’s end to a frame wall.” Pet. 18–19 (citing Ex. 1003 ¶¶ 81–83; Ex. 1007, 4:47–51); see id. at 19–20 (discussing that although “Yamaguchi’s described setting is a sill plate,” the skilled artisan “would have been motivated to use Yamaguchi’s hanger on a wood frame wall in particular so that sheathing could be installed in the space behind the joist as taught by Bundy” (citing Ex. 1003 ¶¶ 81–82)). Based on the foregoing and the complete record before us, we find Petitioner’s cited evidence provides sufficient rational reasons to combine Yamaguchi and Bundy to arrive at the invention of claim 1 with a reasonable expectation of success in doing so.” slip op. at 46

    “Analysis Patent Owner argues, “[w]hile the asserted prior art does teach flanges or sidewalls that are in opposed relation to each other, none of Adams, Cullen, or Yamaguchi teach that these flanges or sidewalls engage each other along a juncture.” PO Resp. 42–43; see PO Sur-reply 6 (Patent Owner arguing, “Adams’s, Cullen’s, and Yamaguchi’s extension flanges are spaced well apart.”). Petitioner’s arguments to the contrary depend wholly on its proposed interpretation of the term “engaging” (Pet. 58–60; Pet. Reply 30–31), which we reject, as discussed above. Although Yamaguchi (and Cullen and Adams) may teach extension flanges in opposed, face-to-face relation, Petitioner does not explain, let alone with particularity or persuasively, how Yamaguchi’s (or Cullen’s or Adams’) flanges, which would wind up located on opposing sides of a joist (where a joist is mounted in the hanger), also teach such extension flanges engaging each other along a juncture—indeed, what juncture? See PO Sur-reply 7 (“Beyond asserting that the word ‘engaging’—standing alone—does not require ‘touching contact,’ [Petitioner] still does not address how the extension flanges of Yamaguchi, Cullen, and Adams can be said to ‘engage’ each other.”). Based on the foregoing and the complete record before us, we find Petitioner does not sufficiently establish that the combination of Yamaguchi and Bundy teaches or even fairly suggests a fire wall hanger wherein “the first and second extension flanges engag[e] each other along a juncture, the juncture arranged to be positioned within the two layers of ⅝-inch-thick drywall,” as recited in dependent claims 38 and 91.” slip op. at 70

    “Judge Rich’s guidance from over thirty years ago: in all aspects of claim construction, “the name of the game is the claim.” In re Hiniker, 150 F.3d at 1369. Claims 38 and 91 recite, in relevant part, a fire wall hanger wherein “the first and second extension flanges engag[e] each other along a juncture, the juncture arranged to be positioned within the two layers of ⅝-inch-thick drywall.” Ex. 1001, 15:28–33, 21:41–46 (emphasis added). On its face, this limitation requires not only that the first and second extension flanges “engage” each other, but also do so “along a juncture.” This recitation of the flanges “engaging” each other along a “juncture” (i.e., a place where things join) strongly supports interpreting the subject limitation to require physical contact (i.e., touching) at least along some portion of the flanges (such as shown in Figure 2, reproduced above). To the contrary, nothing in claims 38 or 91, or their underlying independent claims, suggests that two flanges “engaging each other along a juncture” means or even includes within its scope two flanges “symmetrical to each other across a juncture,” as urged by Petitioner (Pet. 59).” slip op. at 67

    “What these cases and examples clearly articulate, is that whether there is sufficient description in an anticipation reference for linking different disclosures, elements, and embodiments, is particularly case and fact dependent. 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

    “prosecution history and the amendment changing “held at” to “accessible at,” testimony upon which Patent Owner relies to support its position. Specifically, Dr. Medvidović testifies that a person having ordinary skill in the art would have understood the two phrases to be synonymous because, 1) the amendment was not made to overcome a prior art reference, 2) the applicant did not make a statement disclaiming that “being accessible at” does not encompass “being held at,” and 3) the examiner did not object to the amendment as exceeding the scope of the Specification. See Ex. 2005 ¶ 34. We find that Dr. Medvidović’s conclusion is not supported by his reasoning.

An applicant is free to amend a claim at any time during prosecution, even an amendment that may expand the scope of a claim (one made not to overcome a prior art rejection).

Intel Corp., 325 F.3d 1346, 1350 (Fed. Cir. 2003). A term written in means-plus-function form is construed to cover “the corresponding structure, material, or acts described in the specification and equivalents thereof” for performing the recited functions. 35 U.S.C. § 112, para. 6. Use of the term “means” creates a rebuttable presumption that a claim term is a means-plus-function limitation. Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015).

Petitioner also argues that a person of ordinary skill in the art “would have been motivated by the common goals of Andres and Dodd (utilizing risk scoring to inform/prioritize vulnerability remediation) to incorporate Dodd’s adjustment process into Andres’s system.” Pet. 24. “By adding Dodd’s option to adjust the risk score by a fix difficulty value to Andres’s system,” Petitioner argues, “a user of the combined system could more effectively prioritize the easiest to fix vulnerabilities, and therefore decrease the number of vulnerabilities threatening the network.” Id. (citing Ex. 1004 ¶ 37). “This would facilitate the early resolution of easier vulnerabilities,” Petitioner argues, “before they can be exploited in an attack and allow the ‘limited time and resources’ of administrators to be focused on the more difficult vulnerabilities.” Id. (citing Ex. 1003, 18:23–25). Petitioner argues that the enhanced prioritization “would also allow administrators to incorporate business factors such as cost into decisions about remediation.” Id. (citing Ex. 1002 ¶¶ 143–144).” slip op. at 30

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “We find that Petitioner’s description is consistent with the prior art and patent specification currently before us. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself may reflect an appropriate level of skill). For purposes of our Decision, we adopt Petitioner’s definition of the level of ordinary skill in the art as “a Bachelor’s degree in electrical engineering or a similar field, and 1–2 years of experience researching and developing antennas used in RFID applications.” See Pet. 8. In addition, we note that we agree with Patent Owner’s statement that the distinction between the parties’ proposals is not material to any dispute before us and we find that our determinations would be the same under either definition of the person of ordinary skill in the art.” slip op. at 6

    “We are not persuaded that Dr. van der Weide’s cited testimony is of a nature that should lead us to give his testimony no weight. We note that Patent Owner did not move to strike or exclude Dr. van der Weide’s testimony. When considering credibility and weight of evidence below, we consider Dr. van der Weide’s testimony as a whole as well as all other evidence of record and accord it the appropriate weight.” slip op. at 7

    “provide an express construction of the full breadth of a claim term. “The Board is required to construe ‘only those terms ... that are in controversy, and only to the extent necessary to resolve the controversy.’” Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019). As such, we proceed in line with Federal Circuit case law, which “prescribes—deciding only the issues necessary to resolve the dispute before it.” Nichia Corp. v. DSS, Inc., No. 2022-1704, 2023 WL 7211097, at *3 (Fed. Cir. Nov. 2, 2023) (citing Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017)). The Federal Circuit has long recognized that “[c]laim construction is a matter of resolution of disputed meanings and technical scope” and that claim construction may be required in an obviousness context “when the meaning or scope of technical terms and words of art is unclear and in dispute and requires resolution in order to determine obviousness.” U.S. Surgical Corp. v. Ethicon, Inc., 103 F.3d 1554, 1568 (Fed. Cir. 1997). In order to determine whether Petitioner’s obviousness grounds meet their required burden of proof, we need not expressly state the full scope of this claim term. Thus, we are within our authority to proffer a construction that determines the scope of a claim term in a manner sufficient to determine whether the asserted art teaches the claim. In other words, there may be other ways to meet the disputed limitation, but for the purposes of our Decision, it is proper to expressly determine a claim term’s scope only as much as is required to resolve the disputed issues before us.” slip op. at 17

    “the invention(s), but rather as examples of some of the embodiments.” Id. at 25:65–26:1; see also id. at 6:18–20 (embodiments “should be construed as illustrative rather than limiting”), 5:22–24 (“non-limiting example”). The Federal Circuit has noted that “[e]mbodiments in the specification—even if there is only one embodiment—cannot limit the scope of the claims absent the patentee’s ‘words or expressions of manifest exclusion or restriction.’” Apple Inc. v. Wi-LAN Inc., 25 F.4th 960, 967 (Fed. Cir. 2022) (citing Hill- Rom Servs., Inc. v. Stryker Corp., 755 F.3d 1367, 1372 (Fed. Cir. 2014)). After reviewing the complete record, we see no such manifest exclusion or restriction in the ’240 patent specification. We decline Patent Owner’s request to limit the claims to the described single-frequency embodiments. See Phillips, 415 F.3d at 1323. We need not provide further express construction of this claim language for purposes of this Decision.” slip op. at 23
