    “information related to a shared web browsing interaction” is interchangeable with “web browsing interaction data” and, as a result, this portion of the specification should limit the claim term. PO Resp. 18–19 (quoting Ex. 2004 ¶ 40). The quoted portion of Mr. Friedman’s testimony, however, addresses other terms in the specification and not “information related to a shared web browsing interaction.” PO Resp. 18–19 (quoting Ex. 2004 ¶ 40). As such, the testimony cited by Patent Owner does not support Patent Owner’s position. Accordingly, we determine that the patentee has not acted as a lexicographer to set forth a definition of “web browsing interaction data” in the written description. c. Plain and Ordinary Meaning Because the patentee has not acted as a lexicographer to set forth a definition of “web browsing interaction data,” we look to the plain and ordinary meaning of the term. See Edwards Lifesciences LLC v. Cook Inc., from the ordinary meaning will be adopted “when the patentee acted as his own lexicographer and clearly set forth a definition of the disputed claim term in either the specification or prosecution history” (internal quotation marks omitted)); Pet. Reply 5 (Petitioner arguing that “web browsing interaction data” should be afforded its plain and ordinary meaning) (citing Ex. 1034 ¶ 13). Notably, both Dr. Lieberman and Mr. Friedman agree that the plain and ordinary meaning of “web browsing interaction data” is sufficient to inform how one of ordinary skill would have understood the term. Ex. 1034 ¶ 13 (Dr. Lieberman testifying: “The plain meaning of ‘web browsing interaction data’ is data related to web browsing interactions. No additional definition or limitation is required in my opinion, nor is there any special or specific meaning given to the term in the specification of the ’145 patent.”); Ex. 1033, 171:5–16 (Patent Owner’s expert, Mr. Friedman, testifying that “the plain and ordinary meaning is sufficient.”). According to Petitioner, the plain and ordinary meaning is “data related to web browsing interactions.” Pet. Reply 5 (citing Ex. 1034 ¶ 13); Ex. 1034 ¶ 13 (“The plain meaning of ‘web browsing interaction data’ is data related to web browsing interactions.”).

    “Accordingly, we conclude that the plain language of the claims does not require “web browsing interaction data” to be limited to data describing interaction performed on a website by a host device. We turn to the specification because the meaning of “web browsing interaction data” is informed “not only in the context of the particular claim in which the disputed term appears, but in the context of the entire patent, including the specification.” Phillips, 415 F.3d at 1313. The written description does not provide a definition or clear meaning for “web browsing interaction data.” Patent Owner acknowledges the term is not expressly used in the written description. PO Resp. 17. Patent Owner, however, identifies “information related to a shared web browsing interaction” as a term that is interchangeable with “web browsing interaction data.” PO Resp. 18, 29. We recognize the specification term “information related to a shared web browsing interaction” is substantially similar10 to Petitioner’s proposed plain and ordinary meaning of “web browsing interaction data” as “data related to web browsing interactions.” 11 Patent Owner identifies three passages that each describe the present invention as receiving information related to a shared web browsing interaction performed by a host device and performing the shared web browsing interaction based on the received information. PO Resp. 17–18 (block quoting Ex. 1001, Abstract, 3:10–24).

    “When deciding whether issue preclusion applies, we consider whether: (1) a prior action presents an identical issue; (2) the prior action actually litigated and adjudged that issue; (3) the judgment in that prior action necessarily required determination of the identical issue; and (4) the prior action featured full representation of the estopped party. VirnetX Inc. v Apple, Inc., 909 F.3d 1375, 1377 (Fed. Cir. 2018) (citing Stephen Slesinger, Inc. v. Disney Enterprises, Inc., 702 F.3d 640, 644 (Fed. Cir. 2012)). To the extent Petitioner asks us to consider the 01473 IPR institution decision for issue preclusion, we do not. In that decision the Board reached a finding based on the institution standard (showing of a “reasonable likelihood that the petitioner will prevail,” 35 U.S.C. § 314(a)) rather than proof by a preponderance of the evidence, which is before us now (35 U.S.C. § 316(e)). Ex. 1016. Thus, issues before us here were not presented and adjudged in that institution decision. Regarding the 01473 IPR adverse judgment decision, that decision did not require determination of any issues before us, as that decision was based on Patent Owner canceling the challenged claims rather than any determination regarding unpatentability that had been shown by a preponderance of the evidence. Ex. 1014. 2. Collateral Estoppel With Respect to the 00571 IPR We find and determine that the final written decision in the 00571 IPR, and the Federal Circuit’s CommScope decision affirming that decision, satisfies the conditions for applying collateral estoppel because the 00571 discloses materially the same claim limitations7 challenged here, and Patent Owner had full representation throughout the proceedings. Setting aside the factors of issue preclusion for a moment, our reviewing court’s affirmance of our final written decision in CommScope is persuasive authority that supports our prior construction of “packetizing” and Petitioner’s showing that Wu teaches the disputed packetizing limitations under that construction. In addition, issue preclusion prevents Patent Owner from re-litigating the issue of whether Wu teaches materially the same disputed limitation. See Pet. Reply 24; Ex. 1017, 31–34 (final written decision determining obviousness of claims 9, 10, 14, and 16 of the ’473 patent over Wu and Sabat-426); Ex. 1072, 5 (summarizing the final written decision regarding the packetizing limitations), 10–16 (finding no error in the determinations regarding the packetizing limitations).” slip op. at 12

    “a . . . set of radio resources” is not limited to and does not necessarily include configuration information that is required to or used to reconfigure remote radio units. As Petitioner argues, there does not appear to be any indication in the specification and other intrinsic evidence that “digital representation” should be given more than its ordinary meaning, or that an underlying construction of “radio resources” would not be applied to this claim term, which explicitly includes “radio resources.” Pet. Reply 9–10 (citing Ex. 1001, representation” in the specification of the ’499 patent). Our construction is further supported by the language of the claims, which requires that each “set of radio resources” is “for transmission at an antenna of the first remote unit.” Ex. 1001, 14:17–19, 14:22–24, 15:3–5, 15:8–10, 16:6–8, 16:11–13. With respect to the “digital representation” of “set[s] of radio resources,” the specification of the ’499 patent describes that in the downlink (base station to DRU antenna) path for data, RF signals received at the DAU from base station(s), are down-converted, digitized, and further processed resulting in “independently serialized, parallel data streams” that are delivered to DRUs. Ex. 1001, 4:63–5:12. Petitioner contends that this description of delivery of a digitized version of an RF signal to DRUs describes the sending/transmission of a digital representation of the radio. Pet. 9–10. While Patent Owner appears to argue that a “digital representation” of a radio resource would be only an “identifier” of, e.g., an RF carrier (PO Resp. 18), this does not appear to be supported by the specification or the cited testimony of Dr. Chrissan. We do not see a reason to relate “digital representation of . . . a set of radio resources” in the claims to the description in the ’499 patent specification of the remote configuration of DRU parameter settings via the DAU, including detecting or determining radio resources assigned to a DRU and configuring the DRU, turning on and off individual carriers transmitted and received by a DRU.

Because new arguments made for the first time in sur-reply are not permitted, we will only focus on Kerry’s initial challenge to the testimony of Dr. Baldwin. testimony, regardless of the subject of his particular opinions. It is clear that Dr. Baldwin has expertise in some areas of chemistry, while Dr. Milkowski’s experience is focused on other areas and emphasizes food chemistry. These differences in expertise may impact how we weigh the testimony of both witnesses, but that determination should be made in the context of a specific subject and based on the applicability of each witness’s background to the opinions.

Kerry’s argument that Voorde does not disclose starting with a “sterile medium” (PO Resp. 25) is unavailing; as discussed above, we do not interpret anything in claim 1 or the ’304 patent 13 At oral argument, Kerry raised for the first time a claim construction argument that “heat treating,” as recited in the claims, requires heating to a level in excess of what is required in Voorde, and a person of ordinary skill would have understood the term to refer to sterilization. Tr. 33:4–34:19, 55:3–9. We decline to address this late-arising argument fully, but note that we find that the ’304 patent does not support such a limited interpretation of the term “heat treating.” to require a sterile medium, and Kerry does not direct us to anything in the record that would persuade us otherwise.” slip op. at 18

    “Third, and most significantly, Petitioner points to Shimizu, a patent filed in 1999, as repeatedly referring to phosphor as a garnet-based fluorescent material. Reply 3 (citing Pet. 27; Ex. 1013, 10:16–13:50). We agree that Shimizu appears to use the two terms interchangeably. For example, Shimizu states that “[t]he phosphor is specifically garnet fluorescent material” and “the fluorescent material is preferably yttrium- aluminum-garnet fluorescent material (YAG phosphor) activated with cerium.” Ex. 1013, 10:17–30. Patent Owner does not dispute this reading of Shimizu, but argues instead that it is “impermissible to rely on an entirely different reference” in a Reply. See Sur-Reply 4–5 (citing Ariosa Diagnostics v. Verinata Health, Inc., 805 F.3d 1359, 1367 (Fed. Cir. 2015)). For the same reasons discussed above, we do not agree that Petitioner’s use of Shimizu is improper, but is instead a proper response to Patent Owner’s argument that a person of ordinary skill in the art would not have understood Yamazaki to disclose phosphor. Ariosa, relied upon by Patent Owner, confirms that the Board should consider an exhibit “for what it show[s] about the background knowledge that a skilled artisan would have possessed.” Ariosa, 805 F.3d at 1365 (“The Board’s language on its face supports Ariosa’s interpretation of what the Board meant—that the Board was declining to consider Exhibit 1010, even as evidence of the background understanding of skilled artisans as of January 2010, simply because the brochure had not been identified at the petition stage as one of the pieces of prior art defining a combination for obviousness. If that is what the Board meant, the Board erred. Art can legitimately serve to document the knowledge that skilled artisans would bring to bear in reading the prior art identified as producing obviousness.”). The Petition relies on Shimizu to show such background understanding. Pet. 27. Specifically, the Petition states that conventional LEDs “were made using the III-nitride material system, with semiconductor layers formed on sapphire substrates and combined with YAG phosphors to efficiently generate white light output.” Id. (citing Ex. 1013, 10:30–11:35). Thus, Shimizu is properly objective evidence supporting a finding that at least as early as 1999, a person of ordinary skill in the art would have used the terms “phosphor” and “fluorescent material” interchangeably. Moreover, Dr. Schubert’s textbook published in 2018 explicitly references Shimizu. Ex. 1039, 3-4. In this context, we find that Dr. Schubert’s textbook and testimony indicate that a person of ordinary skill in the art, at the relevant time, would have understood the terms to be interchangeable.” slip op. at 20

    “Based on the complete record, Petitioner establishes by a preponderance of the evidence that an ordinarily skilled artisan would have found the sapphire growth substrate obvious in light of Yamazaki’s disclosure. Petitioner cites Schubert to show an ordinarily skilled artisan’s knowledge about conventional blue LEDs as disclosed in Yamazaki, i.e., that “conventional blue LEDs were III-nitride-based LEDs that commonly included sapphire growth substrates.” See Pet. 71–72, 76–77; Ex. 1007 ¶ 27 (stating the disclosed light-emitting chip “is of a publicly known structure”); Ex. 1008, 166 (discussing “commonly used sapphire and SiC substrates”). We credit Dr. Dupuis’ testimony that is consistent with the prior art of record. Ex. 1035 ¶¶ 238, 248–251 (citing Ex. 1008, 166); Ex. 1007 ¶ 27; Ex. 1009, 1:10–17, 4:61–67; Ex. 1012, 243; Ex. 2013, 10:30–11:35. We are not persuaded otherwise by the deposition testimony of Dr. Dupuis pointed to by Patent Owner. PO Resp. 44 (citing Ex. 2016, 53:7– 12). This testimony confirms that Schubert does not explicitly discuss whether the sapphire growth substrate is included in an LED package. Id. (citing Ex. 2016, 53:7–12). However, Patent Owner does not dispute that sapphire growth substrates were commonly used (as confirmed by Schubert) or that a person of ordinary skill in the art would have reasonably expected a blue LED to include a sapphire growth substrate. See PO Resp. 42–43 (stating only that sapphire is one among several materials that could be used as a growth substrate); Sur-Reply 9–10 (same). Petitioner is not required to show that the proposed combination would have been preferred over other alternatives. Infineum USA L.P. v. Chevron Oronite Co. LLC, No. 2020-1333, 2022 WL 3147683, at *6 (Fed. Cir.

Cir. 2004) (“[O]ur case law does not require that a particular combination must be the preferred, or the most desirable, combination described in the prior art in order to provide motivation for the current invention.”). Instead, the question is whether a person of ordinary skill in the art would have understood the disclosure of Yamazaki, in light of the disclosure in Schubert, to teach or suggest the sapphire growth substrate limitation. As discussed above, persuasive evidence in the record establishes that this is true.” slip op. at 38

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner

    “Patent Owner, in focusing on this portion of the ’226 patent disclosure, does not adequately explain why buffer cells and configuration memory cells must be included in the proper construction of “wide configuration data port,” and seeks to import a functional description of the use of a wide configuration data port (“that allows parallel updating of logic cells in a programmable array through use of buffer cells”) into the claim construction. PO Resp. 15–17; PO Sur-reply 2–4. While the discussion in the ’226 patent describes an example of a wide configuration data port used in a specific way that aligns with Patent Owner’s proposal (Ex. 1001, 4:45– 59), other examples of the use of a wide configuration data port are included (id. at 4:59–65), and therefore we do not agree that one of ordinary skill would understand this use to be part of the construction of the term. We agree with Petitioner that the proper construction of the term does not require buffer cells. See Pet. Reply 4–6. Rather, we note that the specification of the ’226 patent contrasts loading of data to an FPGA in a byte serial fashion through a narrow port, which “results in [] long reconfiguration times,” with the use of a wide configuration data port, and therefore we determine that one of ordinary skill would understand the wide configuration data port, in contrast to the byte serial “relatively narrow” port, to include parallel connections between cells in the dies. See Ex. 1001, 4:3– 9. This additionally is consistent with certain arguments by Patent Owner, for example in the Patent Owner’s Response, which opens with a discussion of the “innovative” processor’s arrangement of die-area contacts, such as through-silicon vias, “into a wide configuration data port” and we find that description more consistent with the proper construction of this term. PO Resp. 1–2; see also PO Sur-reply 2–3 (“Arbor’s experts have been consistent that the word ‘wide’ in this term requires a sufficient number, and appropriate arrangement, of connections between the memory die and the programmable array to permit parallel updating of the array.”)” slip op. at 15

  • Claim Construction › Functional claiming / §112(f) means-plus-function › Corresponding structure / algorithm (indefinite if none)Decided for petitioner

    “While corresponding structure need not include all things necessary to enable the claimed invention to work, it must include all structure that actually performs the recited function.” Default Proof Credit Card Sys. Inc. v. Home Depot U.S.A., Inc., 412 F.3d 1291, 1298 (Fed. Cir. 2005). Conversely, structural features that do not actually perform the recited function do not constitute corresponding structure and thus do not serve as claim limitations. Chiuminatta Concrete Concepts, Inc. v. Cardinal Indus., Inc., 145 F.3d 1303, 1308–09, (Fed. Cir. 1998); see B. Braun Med., Inc. v. Abbott Labs., 124 F.3d 1419, 1424 (Fed. Cir. 1997) (“[S]tructure disclosed in the specification is ‘corresponding’ structure only if the specification or prosecution history clearly links or associates that structure to the function recited in the claim.”). Patent Owner’s arguments regarding buffer cells connected with memory configuration cells using die-area interconnections requires that the buffer cells be located on a different die than the memory configuration cells, but the ’226 patent discloses only that “[t]he buffer cells 88 are preferably a portion of the memory die 66” and not that they always are on the memory die, and also that the significantly increased number of connections to the cache memory die may allow the cache memory die to replace configuration bit storage on the FPGA die. Ex. 1001, 4:50–54, 4:59–63. Thus, we decline to require in the corresponding structure that buffer cells or configuration memory are included on any die element. Rather, we find that what is disclosed as actually performing the recited function of “reconfiguring the programmable array within one clock cycle” is “a wide configuration data port and contact points formed throughout the area of the first integrated circuit die element and another integrated circuit die element.” The support for this is found in the ’226 patent’s comparison of the long reconfiguration times through a narrow port (Ex. 1001, 4:3–9) with the time to reconfigure through a wide configuration data port with a significantly increased number of connections (id. at 4:45– 65), and the implementation of this in a module that has multiple dies “which have a number of corresponding contact points, or holes, 70 formed throughout the area of the [die] package” (id. at 4:9–20). The use of a wide configuration data port, as per our construction, implicates two die elements. This was reflected in our preliminary claim construction, for which the corresponding structure described “contact points distributed through the first integrated circuit die element and the third integrated circuit die element.” Dec. on Inst. 29. As the function is “reconfiguring the programmable array within one clock cycle,” one of the die elements is the first integrated circuit die element, which includes the programmable array. slip op. at 19
