“E. Credibility of Dr. Doolittle Patent Owner argues that we should give no weight to Dr. Doolittle’s testimony because, “[o]n cross examination, Prof. Doolittle repeatedly contradicted himself, dodged questions, and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions.” PO Resp. 25. Patent Owner raises two major complaints about Dr. Doolittle. First, Patent Owner argues that he took inconsistent positions by asserting in these IPR proceedings that the claims were entitled to their plain and ordinary meaning, while in the parallel district court proceeding, asserting that certain claim terms were indefinite. Id. at 26–28. Second, Patent Owner argues that Dr. Doolittle “repeatedly dodged questions and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions,” and that “[d]uring cross examination Patent Owner was forced to object to Prof. Doolittle’s nonresponsive answers no less than eighteen times.” Id. at 28. We strongly disagree with Patent Owner’s characterization of Dr. Doolittle’s testimony. We have reviewed the entirety of both of Dr. Doolittle’s depositions. We are impressed with his forthrightness, candor, and good humor in the face of Patent Owner’s counsel’s aggressive questioning. Contrary to Patent Owner’s assertions, we find that his testimony was well-reasoned, forthright, honest, and entitled to significant weight. Dr. Doolittle explained the different claim construction positions We also strongly disagree that Dr. Doolittle’s answers were nonresponsive or “evasive” as Patent Owner argues. Patent Owner’s numerous attempts to “strike” portions of his testimony belie Dr. Doolittle’s efforts to honestly and in good faith respond to Patent Owner’s counsel’s questions. Ex. 2025, 22:10–23:15, 25:9–26:14, 30:14–22, 40:3-9, 58:12–59:1, 60:18–61:13, 65:1–10, 83:15–84:16, 92:15–95:20, 96:18–99:9, 102:22–106:16, 135:3–136:22. An answer is not “non-responsive” simply because it does not conform to the conclusion you want or undermines the logic underlying your questioning. Dr. Doolittle explained his answers and addressed the issues Patent Owner asked about. Accordingly, we decline Patent Owner’s invitation to give Dr. Doolittle’s testimony no weight.

“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 claims do recite a hardware processor “with” a plurality of processing cores; a critical distinction even Patent Owner reads as open-ended, i.e., as a hardware processor that “comprises” a plurality of processing cores. See Resp. 11 (“the claims require a singular ‘hardware processor’ that ‘comprises’ (or ‘with’) multiple ‘processing cores’”). Consequently, the claim language does not support Patent Owner’s proposed construction of “a . . . hardware processor with a plurality of processing cores” as a single multi-core processor. cores it contains” in reliance on a parsed description in the ’034 patent specification: The specification explains: “Each processor can contain one or more processor cores that are capable of single-threaded execution.

“A POSITA would have had an especially strong reason to read these references together because they address the same project, the same MATLAB-based parallel-computing problem, and the same MultiMATLAB command environment. Menon expressly identifies Trefethen’s MultiMATLAB work and then describes a redesigned architecture that preserves the same user-level objective––parallel MATLAB computations—while improving implementation details and extensibility. A POSITA therefore would not view the references as mutually exclusive alternatives. Rather, a POSITA would understand Trefethen as teaching specific MultiMATLAB commands and examples, including Eval, Send, Recv, and the architecture was implemented and improved in a later version. Ex. 1163 ¶¶ 71–72 (emphases added). We find the above reasoning persuasive and adopt it as our own. Petitioner and Dr. Bajaj demonstrate a sound technical motivation for a POSITA—someone having a bachelor’s degree in computer science, computer engineering, or electrical engineering and two years of experience working in the field of cluster computing or parallel processing—to combine Menon and Trefethen: to improve MATLAB’s operational performance and extensibility in a parallel operating environment. Menon builds on Trefethen to improve and extend the parallel processing capabilities of MultiMATLAB: “This system will enable users to access high-performance parallel routines from within the MATLAB environment, to extend the environment with new parallel routines, and to use these routines to develop parallel applications with the MATLAB language.” Ex. 1005 Abstract.

“Plain Meaning of “Substantially Real Time” Instead, the plain meaning of “substantially real time” is readily apparent and understood by a person of skill (POSITA) in the art in the context of data distribution or transmission of the ’128 patent as referring to an acceptable time delay (i.e., “a fraction of real time”) between distribution center 18 and user device 12, via network 14, shown in Figures 1–2 of the ’128 patent and, as such, is consistent with the ‘128 patent’s specification and Dr. Lippman’s Declaration (Ex. 1003, ¶¶ 79, 126). Because the plain meaning of “substantially real time” as understood by a POSITA is readily apparent, there is no reason for the Board to consider Patent Owner’s clarification of “substantially real time” based solely on extrinsic evidence, i.e., counsel argument, Mr. Johnson’s declaration (Ex. 2007, ¶¶ 27, 29–30, 33, 39; Ex. 1018, 38:13–39:20) and Dr. McCulloh’s declaration (Ex. 2009, ¶ 19). For example, Patent Owner, relying upon Mr. Johnson’s testimony, clarifies the term “substantially real time” requires either (1) “playback while transmission is ongoing” (PO Resp. 30), or (2) “[a] coordinated system behavior in response to a user’s request” “in which a user request triggers coordinated operations, including locating content across distributed systems, routing that content, and initiating playback while transmission is ongoing” (PO Sur-Reply 4 (citing Ex. 1001, 2:67–3:2, 6:23–35)). However, Patent Owner’s shifting position regarding “substantially real time” is not commensurate with the plain reading of the term. Based on the plain meaning of “substantially real time,” we are persuaded by Petitioner that Yurt explicitly discloses transmitting data at least in “real time,” preferably “less than real time” or “a fraction of real time” for playback. Pet. Reply 9 (citing Ex.1005, code (57), 1:66–2:4, 4:68– 5:3 (teaching distributing “digital audio” in “less than real time” and in “a fraction of real time,” where the receiving system may “decompress in real time the requested material as it is distributed by transmission system 100”)).” slip op. at 36

“teaches or renders obvious all limitations of claim 1, Petitioner also provides sufficient motivation or reasoning with a rational underpinning to combine Yurt and Logan. Specifically, Petitioner, relying on Dr. Lippman’s declaration (Ex. 1003, ¶¶ 62–73), asserts “a POSITA would have been motivated to combine Yurt with Logan for several reasons, discussed further below. Combining Logan’s usage log teachings with Yurt’s improved audio file accessibility (e.g., via popularity) to track additional user request information would have been obvious, beneficial, and predictable.” Pet. 19 (citing Ex. 1003, ¶¶ 62–72). According to Petitioner, because “Logan teaches implementation details for tracking user/usage data for billing purposes and adapting preferences ‘based on actual usage,’” “[a] POSITA would have thus been motivated to combine Yurt’s teachings (e.g., tracking information about requested items like item popularity) with Logan’s teachings (e.g., storing user data and usage information in response to user requests).” Id. at 19–20. “This would have been merely the use of a known technique (Logan’s tracking of user and usage data in response to user requests) to improve a similar method in the same way (Yurt’s tracking of information about user-requested items).” Id. at 20 (citing Ex. 1003, ¶¶ 67– 68). According to Petitioner, [T]he combination is straightforward: use Logan’s known technique for recording user data with Yurt’s existing item database teachings. See Ex. 1005, 12:28–57, 10:66–11:4; Ex. 1006, 5:33–42, 6:27–35, 8:49–58; Pet. 19–23. Since Yurt already teaches using its item database to track item popularity and request information, no modification to Yurt’s architecture is necessary. Logan merely confirms when and how to store the user information. Pet. 19–21. A POSITA would have found the combination obvious for all the reasons Dr. Lippman provided.

“meaning of “icon” as claimed, including the dependent claims, the specification, the prosecution history, and the extrinsic evidence including expert testimony and dictionary definitions, we determine that the plain meaning of “icon” is readily apparent from the claims themselves. See Phillips, 415 F.3d at 1314 (“In some cases, the ordinary meaning of claim language as understood by a person of ordinary skill in the art may be readily apparent even to lay judges.”). We find that the plain meaning of “icon” as claimed encompasses at least “textual elements” because claim 20 recites “the icons comprise textual elements.” See id. (“Other claims of the patent in question, both asserted and unasserted, can also be valuable sources of enlightenment as to the meaning of a claim term.”). We highlight that the additional intrinsic evidence cited by the parties is consistent with the plain meaning. For example, Figures 1 and 2 of the specification show icons comprising textual elements. As another example, during prosecution of the ’058 patent, the Examiner found that the claimed icons were taught by textual hyperlinks. Ex. 1002, 586, 592. In order to overcome the Examiner’s rejection and obtain an allowance (id. at 641–50), applicant subsequently amended the claims to recite “specifically designed,” thus implicitly conceding to the Examiner’s interpretation of icon as encompassing textual hyperlinks. Id. at 625–640; see PO Resp. 43–44 (citing Ex. 1002, 626–27, 645–46) (acknowledging that the Examiner allowed the claims because applicant amended the claims to recite “specifically designed for containing a set of icons.”).” slip op. at 11

“Requiring an element to be "specifically designed" for another element narrows the claim because it requires more than the first element being merely capable of being used with the second element. The term "configured to" is generally construed narrowly to mean "made to" and "designed to" rather than broadly to require merely "capable of". See In re Giannelli, 739 F. 3d 1375, 1379-80 (Fed. Cir. 2014) (the phrase "configured to" requires more than "mere capability." Rather, that term is synonymous with "made to" and "designed to."). However, rather than use "configured to", in order to avoid any confusion as to the narrower scope of the claims as amended, Applicant herein directly and explicitly requires "designed to." In re Giannelli at 1379-80 (Fed. Cir. 2014) (reversing an obviousness rejection because (1) the claims were properly construed narrowly to mean "designed to" and not broadly to encompass merely "capable of", and (2) the USPTO had not explained the motivation for modifying the prior art to meet the "design to" requirement) See also MPEP 2111.04, citing to In re Giannelli, for the proposition that a claim can be narrowed to require that it be "designed and constructed to be used" in a specific manner (as a rowing machine in the case of In re Giannelli). Logan has not been specifically designed and constructed in the required manner, so it does not cure all deficiencies of the primary reference Iki (which lacks any tree menu structure). Logan describes only "remote web" pages 90, 95 that are merely pages retrieved from Web browsing and stored in a web computer 25. Iki as modified by Logan would result on in a tree menu structure wherein not all levels of the tree included the required selection pages specifically designed for containing the claimed set of icons.
