“1. “closed loop” The term “closed loop” is recited in each independent claim. Petitioner asserts that in the Delaware action , the district court construed “closed loop” as “gas pathway within a display housing containing gas that is essentially isolated from external air.” Pet. 11 (citing Ex. 1026, 1). Petitioner asserts that the district court’s construction is the proper construction, in light of the specification and the prosecution history of the ’740 patent. Id. at 11–12. Petitioner explains: The ’740 patent refers to the gas/air, circulating through a closed loop as the circulating gas/air and also as the “isolated gas.” (Ex. 1001, 9:64–10:3, 10:7–9, 10:56–58, 11:30–12:6 (claims reciting circulating gas/air), 3:30–[39], 3:50–52 (specification referring to gas in the closed loop as “circulating gas” and “isolated gas”), FIG. 1.) Moreover, as noted above, the Applicant distinguished the claims from the Thielemans prior art based on the argument that the closed loop must be separate from and in addition to the open loop. (Ex. [1031], pp. 44-45, 160 (Responses filed on 01/07/2019 and 08/15/2019).) The Court’s “closed loop” construction should apply here, though Applicant notes that this claim construction does not affect the applicability of the prior art in this Petition because the art teaches the separate loops. Id. at 12. Petitioner’s characterization of the prosecution history with respect to the Thielemans reference is inaccurate. Our review of the cited portions of the prosecution history reveals that the Applicants did not argue to the Examiner that the closed loop and the open loop must be isolated from each other and cannot mix. Rather, the Applicants argued that Thielemans discloses having an open loop or a closed loop, not both an open loop and a closed loop. Ex. 1031, 44–45, 160. The Applicants also argued that Thielemans’s closed loop is not “about” and is not “encircling” the electronic image assembly. Id. at 160.

“appear nowhere outside of the claims in the ’595 patent. This fact alone tends to undermine Patent Owner’s suggestion that the “posterior surface” must be distinct from the “rear side.” In addition, Patent Owner’s cited portions of the Specification merely refer to the “posterior surface” as being the surface opposite that on which the LEDs are mounted to which heat from the LEDs is transferred. See Ex. 1001, 4:53–55, 4:57–60. They are inconclusive as to whether the “posterior surface” must be distinct from the “rear side.” Further, Mr. Gershowitz’s testimony in support of a “distinct” construction is based on his interpretation of the words “on the” in claim 4’s recited “posterior surface on the rear side of the PCB.” Ex. 2006 ¶ 128. Specifically, he testifies that “[i]f the posterior surface was the rear side of the PCB, the claim would have said so.” Id. He does not cite any support in the Specification of the ’595 patent for his interpretation. See id. Given that his testimony amounts to speculation divorced from the context of the Specification, Mr. Gershowitz’s testimony is entitled to little weight. We also have considered Mr. Smith-Gillespie’s testimony in support of Petitioner’s contention that an ordinarily skilled artisan “would have understood that the rear outermost surface of the PCB is the recited ‘posterior surface.’” Pet. Reply 20 (citing Pet. 83; Ex. 1002 ¶ 243). He cites a passage in the Specification of the ’595 patent that states: “The PCB may comprise a metal core PCB and the posterior surface of the PCB may be metallic so that air within the constricted convection channel may cool the metallic posterior surface (and subsequently the backlight assembly) more easily and efficiently.” Ex. 1002 ¶ 243 (emphasis omitted) (quoting Ex. 1001, 4:60–65). We accord Mr. Smith-Gillespie’s testimony more weight than Mr. Gershowitz’s testimony given that Mr. Smith-Gillespie’s testimony is rooted in disclosures about metal core PCBs in the ’595 patent.

“legally sufficient motivation for modifying Paulraj, but only attempted to show that the modification “could” have been made by one of ordinary skill in the art which is not enough for a showing of obviousness. Sur-reply 8–9. We disagree with Patent Owner. Establishing that certain technique was well-known to one of ordinary skill in the art at the effective filing date of the challenged patent constitutes sufficient motivation to make a modification in accordance with what was well-known in the art to one of ordinary skill, absent factors not present here. Indeed, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417. That would be the situation where a technique was well-known to one of ordinary skill in the art, unless there is actual difficulty in making the application. The “improvement” here, although not articulated by Petitioner, is inherent with the technique, not requiring use of separate antennas for transmitting and receiving, i.e., eliminating the need for additional parts. Further, it is not necessary to show that a modification is the “best option,” because any “suitable option” would suffice. See Intel Corporation v. Qualcomm Incorporated, 21 F.4th 784, 800 (Fed. Cir. 2021). Here, Patent Owner does not assert that one of ordinary skill in the art would have had difficulty modifying Paulraj to use some of the same antennas both for transmitting and for receiving. Nor does Patent Owner dispute that it was well known to one of ordinary skill in the art to use the same antenna(s) for both transmitting and for receiving. We further note the following description in the Specification of the ’083 patent: “The typical CT/MD [cellular telephone/mobile device] has one transmitter and one receiver (T/R), with one antenna.” Ex. 1001, 1:47–48. That statement is fully consistent with Petitioner’s assertion that it was well-known to use the same antenna for transmitting and for receiving. For the foregoing reasons, notwithstanding Patent Owner’s arguments to the contrary, we determine that Petitioner sufficiently has shown that it would have been obvious to one of ordinary skill in the art to modify Paulraj such that some of the same antennas would be used both for transmitting and for receiving, according to limitations 1[b], 1[d], and 1[e].” slip op. at 36

Patent Owner confirmed at the Oral Hearing its understanding that arguments raised in its Preliminary Response and not reasserted in its Patent Owner Response were not appropriate for consideration during trial.

“Petitioner contends that a person of ordinary skill in the art, “[a]s of the claimed priority date of July 3, 2014, . . . would have been a person with a bachelor’s degree in electrical engineering or its equivalent and two years of experience in the field of electrical engineering including some experience in design of battery charging systems.” Pet. 21 (citing Ex. 1003 ¶¶ 19–30). Patent Owner “does not propose a different level of skill in the art[.]” PO Resp. 16. In light of the record before us, we adopt Petitioner’s proposal regarding the level of ordinary skill in the art, because it is supported by the testimony of C.

As neither party proposes an express construction for our consideration and because we determine that claim construction is not necessary, we do not expressly construe any claim terms.

“arguments relating to whether the prior findings are “necessary to the determination” or whether estoppel applies to arguments relating to Richardson being inoperative. See Pet. Reply 27. Nor does Petitioner respond to our inquiry about whether collateral estoppel maybe applied on a limitation by limitation basis. See Pet. Reply 27. At the hearing, however, Petitioner confirmed that resolution of the issue is not necessary to our final determination. JUDGE ROSS: Do we even need to decide the collateral estoppel issue? I mean, it seems to me that if your petition clearly made out your case for the combination of Richardson and Zhao, then we don't even need to reach that. MR. CHANDRA: That’s exactly right, Your Honor. That is our position, as well. We believe collateral estoppel applies, but you don't need to decide that issue in order to find these claims unpatentable. As I mentioned before, these are the same references. We have fairly sought out all of the portions of Richardson, we cited to specific portions. Not just relying on collateral estoppel, but the teachings of the reference itself. So, while this is an issue, we believe that collateral estoppel should apply. It does not have to apply in order to find the challenged claims unpatentable. Tr. 19:9–20. We are persuaded, as discussed in Section II.G., that Petitioner has shown where Richardson in combination with Zhao meets each limitation of the claims of the ’203 patent. Accordingly, we need not address whether Petitioner has demonstrated sufficiently that collateral estoppel applies here.” slip op. at 14

“With respect to Petitioner’s allegations that rest on AAPA, we determine Petitioner has failed to show that claims 2, 10, and 11 are unpatentable. Our rules require that a petition for inter partes review must base the asserted challenges on “prior art consisting of patents or printed publications.” 35 U.S.C. § 311(b); 37 C.F.R. § 42.104(b)(2) and (4). And, a petitioner who relies on applicant admitted prior art as the basis, or part of the basis, of a ground, runs afoul of § 311. Qualcomm, 134 F.4th at 1365; see also USPTO Memorandum, Enforcement and Non-Waiver of 37 C.F.R. § 42.104(b)(4) and Permissible Uses of General Knowledge in Inter Partes Reviews (Jul. 21, 2025), available at www.uspto.gov/sites/default/ files/documents/aapa_memo_final__signed.pdf. We acknowledge but reject Petitioner’s position that its combinations discussing AAPA do not “rely” on AAPA but rather rely on U.S. Patent No. 5,793,185 (“the ’185 patent”), described in the ’203 patent as prior art. Pet. Reply 26. A petition for inter partes review must identify, “in writing and with particularity, each claim challenged, the grounds on which the challenge to each claim is based, and the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3); 37 C.F.R. § 42.104 (b)(4). Here, Petitioner’s contention that the Grounds 2 and 5 actually rely on the ’185 patent when discussing AAPA is inconsistent with the Petition. In particular, the Petition does not cite to or direct our attention to any specific details from the ’185 patent to support its challenges. See generally Pet. 54–57, 76–77. Accordingly, Petitioner has failed to show, by a preponderance of the evidence, that claims 2, 10, and 11 would have been unpatentable over the combination of Richardson, Zhao, and AAPA as well as over the combination of Yu, Paparrizos, and AAPA. Petitioner’s alternative allegations based on Epower-20/Epower-21 are considered below.” slip op. at 18

“Because there is no dispute as to the scope and meaning of these terms, and for consistency with the Decision on Institution, we apply the meaning of the terms “blur” and “distance magnitude” as stated above where applicable. However, we note that our determination does not hinge on the meaning of these terms. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

“it was “known to utilize ‘cues’ to help the user know what gesture to utilize and whether they are correctly performing the gesture (e.g., graphics such as movable images that help the user visualize the correct gesture and how to complete it successfully).” Pet. 40 (citing Ex. 1005, Abstract, ¶¶ 54, 62, 73). This sentence does not cure the deficiency noted above regarding Petitioner’s reliance on Ahn’s graphic shadow moving with a gesture. Chaudhri is relied on for the proposition that, Ahn’s graphic shadow is “[i]ndeed” a movable image known to give a user a visual cue. Id. But no such “cue” is provided in Ahn by the graphical shadow alone, because there is no movement of that object. The Petition does not present argument that a Chaudhri object is the movable object or how any of Chaudhri’s teachings of movable objects would have suggested to modify Ahn “to thereby move” the graphical shadow.” slip op. at 18

“the theory that Ahn’s graphic shadow moves. Reply 3−4. Petitioner interprets the sentences in Ahn we have analyzed above in conjunction with testimony of Dr. Terveen to argue that temporal descriptions in Ahn make it obvious for a person of ordinary skill in the art to drag in the right direction while continuing to press the graphic 1800. Id. (citing Exs. 1004 ¶¶ 117−119, Ex. 1023 ¶ 10). The Petition, however, relies on an Ahn disclosing a moving graphic shadow according to the embodiment of Figure 18(a), as described in paragraph 118. Petitioner now changes its theory of how Ahn’s graphic shadow would move according to paragraph 119, i.e., that although the graphic shadow is merely pressed (in the embodiment shown in Figure 18(b)) it would also be dragged while pressed. Reply 3. Not only is this a shift from the theory Petitioner presents in the Petition, it is not persuasive. As Patent Owner argues, and we agree, there is no cogent explanation for modifying the graphic shadow embodiment of Figure 18(b), especially in light of Ahn’s disclosure that the graphic shadow disappears when pressed and the menu list is displayed as emerging. Sur-reply 2−3. In other words, Petitioner’s new argument does not account for Ahn’s teaching that the objective of the graphic shadow is merely to notify the user of the start of the gesture, and once that start of the gesture is detected (the press on the graphic shadow), paragraph 119 informs us that there is no longer a need for the graphic shadow—it disappears from the display. Ex. 1004 ¶ 119. The Petition does not offer any argument for a theory in which the gesture of paragraph 119 (the press, not a touch and drag operation) results in graphic 1800 disappearing, while also moving during the disappearance. We are mindful that “[i]t is impermissible within the framework of section 103 to pick and choose from any one reference only so much of it as will support a given position to the exclusion of other parts necessary to the full appreciation of what such reference fairly suggests to one skilled in the art.” Bausch & Lomb, Inc. v. Barnes-Hind / Hydrocurve, Inc., 796 F.2d 443, 448 (Fed. Cir. 1986)). Consequently, we determine that Petitioner’s argument in Reply belatedly relying on the different embodiment of paragraph 119 is improper new argument, and that even if considered it is not persuasive.” slip op. at 20
