Taking into account the arguments presented by Patent Owner in the preliminary record, we determined that the information presented in the Petition established that there was a reasonable likelihood that Petitioner would prevail with respect to its unpatentability challenges. Pursuant to 35 U.S.C. § 314, we instituted this proceeding on June 20, 2023, as to all challenged claims and all grounds of unpatentability presented in the Petition.

      “record, we adopted the following definition of the level of ordinary skill in our Decision on Institution: [A] POSITA would have had a bachelor’s degree in a pertinent discipline, such as mechanical engineering, physics, applied physics, product design, or a related field, and would also have had 2–4 years of experience working with electronic displays, including the thermal management, product design issues, and failure modes, associated with such displays, or 5–7 years of experience in the field working with electronic displays and would have developed a similar understanding of thermal management, product design issues, and failure modes, associated with electronic displays. Dec. on Inst. 11. The parties’ positions have not changed since the time of institution, and we discern no reason to change the definition. Thus, we apply the same definition. We are satisfied that this definition comports with the level of skill necessary to understand and implement the teachings of the ’595 patent and the asserted prior art. Notwithstanding, we note that our analysis would not change if we adopted either party’s proposed definition in toto.” slip op. at 12

      “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. It also gives some credence to the notion that the “posterior surface” and the “rear side” could be one and the same.

      “The question before us, therefore, is whether the Petitioner’s proffered explanation that it has proposed a different claim interpretation before the Board because the District Court may decline to adopt the narrower claim interpretations it advocates there is sufficient. We find that Petitioner’s explanation is sufficient because it follows the Director’s exemplary logic. Whether a district court has already or might in the future decline to adopt constructions that a petitioner proposes in related district court litigation merely reflects the timing of when a dispute over claim interpretation will be resolved. The Director and Patent Owner both recognize that, to resolve the dispute over claim interpretation that exists here, a decision-maker must determine “a single claim construction that best captures the true meaning of the patent claim.” Remand 4; PO Remand Br. 3. Based on the record presented by the parties to date in this proceeding, no dispute exists that the disputed claim terms mean what Patent Owner says they mean in the Litigation.

      “articulated a reason why a person of ordinary skill in the art would have combined the teachings of Sudre, Lee, and Penven. Prelim. Resp. 60–63. In particular, Patent Owner argues that a person of ordinary skill in the art “would not have been motivated to look into Penven to modify the teachings of Lee because Lee and Penven disclose substantially different structures.” Id. at 60–61. This argument does not address Petitioner’s proposed reason to combine, which looks to Lee and Penven each to modify Sudre, not to Penven to modify Lee. See Pet. 79–81. In addition, “[c]ombining the teachings of references does not involve an ability to combine their specific structures.” In re Nievelt, 482 F.2d 965, 968 (CCPA 1973). In other words, “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” In re Keller, 642 F.2d 413, 425–26 (CCPA 1981). Petitioner provides “some articulated reasoning with some rational underpinning” to combine the teachings of Sudre with those of Lee and Penven. KSR Int’l Co. v.

      “ordinary meaning, “primary” and “non-primary” cells are all cells that the WTRU is connected to (PO Resp. 16), the plain language in claim 1, and similarly in claim 7, does not require a “primary” node or “non-primary” cell to have a connection to the WTRU. See Ex. 1001, 10:38−56; 11:11–26. We find unavailing Patent Owner’s contention that the claims require that the WTRU “be connected to more than one cell,” wherein cells that are “associated with a wireless network node,” but are not connected to the WTRU “at the same time” cannot be “primary” or “non-primary” cells. PO Resp. 16. In the ’803 patent, nothing in the Specification clearly limits “primary” and “non-primary” cells as Patent Owner proposes. Prelim. Resp. 16. Patent Owner points to the Specification of the ’803 patent to show that, for softer handover, the WTRU is connected “with more than one cell [] which are controlled by the same Node-B,” and “[o]ne of the[se] cells 808 may be designated as a primary cell 808a, while other cells are designated as a non-primary cells 808b.” Id. (alterations in original) (citing Ex. 1001, 8:44–46, 9:4–6, Figs. 8A–B). However, this portion of the Specification (describing a softer handover embodiment in which a cell “may be designated” as a primary while other as non-primary) does not provide a clear definition to warrant interpreting the “primary” and “non-primary” cells as requiring “connection” to the WTRU “at the same time.” Id. That is, nothing in the Specification clearly precludes “primary” and “non-primary” cells from being “source” and “target” cell, as Patent Owner contends. PO Resp. 16. and the Specification, we determine that the terms “primary” and “non-primary” recited in claims 1 and 7 are not limited to cells connected to a WRTU at the same time. We determine no further explicit construction of this term is necessary to resolve the controversy. See Vivid Techs., 200 F.3d at 803.” slip op. at 8

      “f) Motivation to combine Ericsson and TS 25.331 Petitioner contends that a “POSITA would have been motivated to combine Ericsson and TS 25.331 because they are directed to similar technologies and a skilled artisan would have understood the benefits of combining these two references,” and “would have understood that there was a high likelihood of success in making the combination.” Pet. 34 (citing Ex. 1003 ¶¶ 156–157). In particular, the references “are both reasonably pertinent to the problem faced by the inventor, namely protocols for handover in a telecommunications system.” Id. (citing Ex. 1003 ¶ 158).

At this stage, we find that testimony credible and supported by the evidence presently of record. After reviewing the preliminary record (including Clearwater’s contentions, the cited portions of Nakagawa, and the testimony of Clearwater’s expert), we find, preliminarily, that Nakagawa discloses or otherwise suggests each claim element in the manner recited by claim 1. Thus, on the current record, Clearwater demonstrates a reasonable likelihood that challenged claim 1 is unpatentable as obvious over Nakagawa. We need not decide Clearwater’s challenge of the dependent claims based on Nakagawa alone nor its challenge of claims 1–3 based on Nakagawa and Tanner.

Patent Owner contends that: A [person of ordinary skill in the art] at that time would be a person with a bachelor’s degree in computer science, computer engineering, or a closely related discipline and two years of relevant professional experience in software engineering or a 2 US Patent No. 6,119,155 issued Sept. 12, 2000 (Ex. 1004). 3 US Patent No. 6,037,934 issued Mar. 14, 2000 (Ex. 1005). 4 US Patent No. 6,353,839 B1 filed Apr. 30, 1998, issued Mar. 5, 2002 (Ex. 1006). 5 US Patent No. 6,493,702 B1 filed May 5, 1999, issued Dec. 10, 2002 (Ex. 1008). 6 US Patent No. 6,138,158 issued Oct. 24, 2000 (Ex. 1007). similar field. Alternatively, someone with an advanced degree and less professional experience or less education and more professional experience would also qualify as a [person of ordinary skill in the art].

      “We agree with Patent Owner that the plain meaning of “beforehand locally stored” requires the claimed selection pages to be present on the local device before a user conducts a preliminary search. Even if we were to agree with Petitioner that a user could download and store selection pages to the local device, such downloading and storing must occur before the user locally performs a preliminary search in order for the selection pages to be “beforehand locally stored” within the scope of claims 1 and 27. We construe the terms “said selection pages being beforehand locally stored” recited in claim 1 and “said selection pages being . . . beforehand locally stored” recited in claim 27 as requiring the selection pages to be locally stored before a user locally performs a preliminary search.” slip op. at 8

      “We agree with Petitioner. Rossman discloses times when accessing a web page over the network is unavoidable. Col. 8; see Pet. 21. Himmel teaches that using a bookmark to directly access a desired page is quicker than navigating through intermediate pages to get to the desired page. See Pet. 22–23, 25. Patent Owner does not address Rossman’s disclosure that a request to a network web page may be unavoidable, and does not address Himmel’s disclosure of making a direct request to the desired web page to save time and conserve network resources when accessing the desired web page. On this record, we agree with Petitioner that adding Himmel’s bookmarks to Rossmann’s cards provides the benefit of directly accessing a particular web function, thus reducing network traffic and data usage as compared to navigating multiple web pages to arrive at the particular web function.” slip op. at 9

Under these circumstances, our reasons for instituting review based on Deltran’s petition apply with equal force to the “substantively identical” Petition filed by ADC Solutions. Id.

Patent Owner does not contest any facts alleged by ADC Solutions in its Motion for Joinder. Having considered Petitioner’s Motion for Joinder, we determine that joinder of the instant proceeding with in the Deltran IPR is appropriate. For the reasons in our Decision Instituting Review in Deltran IPR, we find that the Petition in this proceeding also warrants institution of inter partes review and that joinder is appropriate. Accordingly, we grant Petitioner’s 2 We understand the “understudy role” as including Petitioner not making any oral argument or presentation during telephone conferences with the Board.” slip op. at 4

      “Additionally, a person having ordinary skill in the art would have known and been familiar with information elements (IEs) that specified an RLC reordering timer value based on (1) general knowledge that IEs carried information in RRC messages and (2) that 3GPP TSs describe an IE carrying recording timer duration information for the RLC layer. See Ex. 1003 ¶ 151; Ex. 1014, 219–20. Accordingly, it would have been obvious to a person having ordinary skill in the art “that the PDCP timer information, which used similar variables as its RLC counterpart (Koskinen, ¶¶37-38), would also be carried in a PDCP configuration IE.” Ex. 1003 ¶ 151.” slip op. at 13
