“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.

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.

“e) Conclusion on Motivation to Combine Harris and the FBDIMM Standards On this record, Petitioner has shown by a preponderance of the evidence that a person of ordinary skill in the art would have combined Harris and the FBDIMM standards since Harris states that its memory module may include fully buffered DIMMs (FBDs). Ex. 1023 ¶ 9. We agree that one of ordinary skill in the art would have recognized Harris’s mention of FBDIMMs as a standard and looked to the FBDIMM Standards for information concerning the voltage values standardized for use in an FBDIMM. Ex. 1027, 83; Ex. 1028, 9. For these reasons and others set forth above, we determine that one of ordinary skill in the art would have combined Harris and the FBDIMM Standards with a reasonable expectation of success.” slip op. at 41

“H. Motion to Exclude Petitioner seeks to exclude materials referenced in three URLs submitted with Patent Owner’s Sur-Reply on August 4, 2023. Paper 33 (citing Paper 31, 1 n.2, 24, 26). Because we do not rely on any of these URLs in a manner adverse to Petitioner, we dismiss the Motion to Exclude as moot.” slip op. at 89

- Skill levelSkill level petitioner adoptedDecided for petitioner
“Petitioner asserts a person of ordinary skill in the art “would have had an advanced degree in electrical or computer engineering, or a related field, and two years working or studying in the field of design or development of memory systems, or a bachelor’s degree in such engineering disciplines and at least three years working in the field.” Pet. 7–8 (citing Ex. 1003 ¶ 61). Petitioner contends that additional training can substitute for educational or research experience, and vice versa. Id. at 8. Petitioner asserts that such a hypothetical person would have been familiar with the JEDEC industry standards, and knowledgeable about the design and operation of standardized DRAM and SDRAM memory devices and memory modules and how they interacted with a memory controller and other parts of a computer system, including standard communication busses and protocols, such as PCI and SMBus busses and protocols. Id. Petitioner further contends that such “a hypothetical person would also have been familiar with the structure and operation of circuitry used to access and control computer memories, including sophisticated circuits such as ASICs, FPGAs, and CPLDs, and more low-level circuits such as tri-state buffers.” Id. Petitioner further asserts that such “a hypothetical person would further have been familiar with voltage supply requirements of such structures (e.g., memory modules, memory devices, memory controller, and associated access and control circuitry), including voltage conversion and voltage regulation circuitry.” Id. Patent Owner indicates “[f]or the purposes of this [Response], Patent Owner is applying the level of ordinary skill in the art proposed by Petitioner.” Resp. 2. The evidence that Petitioner presents mostly applies to the educational level and experience of workers in the field, but also touches upon other factors as well, including problems and solutions in the prior art and complexity of the technology. See Pet. 7–8. We find Petitioner’s proposal is consistent with the level of skill in the art reflected by the ’054 patent and the prior art of record, and, therefore, we adopt Petitioner’s proposed level of ordinary skill in the art, with the exception of the open-ended language “at least,” which introduces ambiguity and may encompass skill levels beyond ordinary.” slip op. at 11
- Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for patent owner
“The District Court’s Claim Construction Order (Ex. 2032) issued after our Institution Decision (Paper 11). Although Petitioner argued in the District Court litigation that the claim preambles were not limiting, Petitioner does not appear to maintain that argument here following the District Court’s determination that the preambles are limiting. Ex. 2032, 35. Since the term is recited in both the preambles and bodies of these claims, there is evidence that the inventors of the ’054 patent intended the term to limit the claim, as the District Court determined. See Catalina Mktg. Int’l., Inc. v. Coolsavings,com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (citing Bell Commc’ns Rsch., Inc. v. Vitalink Communications Corp., 55 F.3d 615, 620 (Fed. Cir. 1995) (“dependence on a particular disputed preamble phrase for antecedent basis may limit claim scope because it indicates a reliance on both the preamble and claim body to define the claimed invention.”)).” slip op. at 16
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner
“We agree with Petitioner’s contention that “memory module” is not limited to “main memory modules . . . designed to connect to the primary memory controller.” See Reply 2. The ’054 patent states In certain embodiments, the device contains a high density Flash memory with a low density DRAM, wherein the DRAM is used as a data buffer for read/write operation. The Flash serves as the main memory. Ex. 1001, 11:3–6 (emphases added). This is the only mention of “main memory” in the ’054 patent. That the Flash memory serves as “main memory” in “certain embodiments” implies that there may be other embodiments in which this is not the case. Accordingly, we agree with Petitioner that the term “memory module” is not limited to “main memory modules . . . designed to connect to the primary memory controller.” We agree with Patent Owner that the “memory module” includes structure to connect with a “host system” including its memory controller. See, e.g., Ex. 1001, code (57), 12:52–59. The claims do not mention a “memory controller,” but they do mention that the “memory module” has an “interface” to connect with a “host system.” Ex. 1001, 38:20–25 (claim 1), 39:63–65 (claim 16), 41:6–8 (claim 24). That the “memory module” has structure for connecting to the host system’s memory controller may thus be implied from the claims. We agree with Petitioner that the District Court’s determination was that the preambles (presumably of claims 1, 4, 6, 11, 16 and 25) are limiting. Ex. 2032, 35. To the extent that the District Court’s determination construed “memory module” to include structure necessary to connect to a memory controller, our construction of “memory module” is consistent.” slip op. at 16
