    “RS6000 with Menon, namely because RS6000 provides an overview of the IBM SP2 multiprocessor and Menon teaches the use of “IBM SP2, a modern high performance distributed memory multiprocessor” used in the MultiMATLAB system. Id. at 24–25 (citing Ex. 1003 ¶¶ 142–145; Ex. 1005, 5–6, 14; Ex. 1007, 1, 11). The Petition also explains why POEref pertains to the field of cluster computing in a parallel operating environment.

    “skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). Patent Owner argues that Menon teaches away from a combination with Trefethen because “Menon expressly states that Trefethen’s first-generation architecture is inadequate for the objectives that motivated the newer design.” Resp. 35–37. The evidence does not support Patent Owner’s position. First, Patent Owner’s teaching away argument is inconsistent with the strong evidence of a motivation to combine Menon and Trefethen discussed above. Second, Patent Owner’s teaching away argument is contrary to the evidence of record for the reasons given in Petitioner’s Reply. Reply 13–15 (e.g., “Menon explicitly cites Trefethen and explains that Menon builds on the teachings of Trefethen.”) (citing Pet. 22; Ex. 1003 ¶ 70; Ex. 1005, 1–3; Ex. 1163 ¶¶ 47–53). We are further persuaded by Dr. Bajaj’s reply testimony: the “MultiMATLAB teachings in Trefethen. In fact, Menon describes enhancing the system of Trefethen. For example, Menon describes a list of “goals” already achieved by MultiMATLAB and then states that the architecture has been “redesigned to achieve two further goals.” One of these two “further goals” is “extensibility,” which Menon achieves by its description of adding “MEX routines” to the system of Trefethen. Far from showing an “incompatibility” between Menon and Trefethen as the POR argues, Menon’s addition of the “MEX routines” to MultiMATLAB shows that such a modification was within the capabilities of a POSITA, because the authors of the Menon paper actually implemented the modification. Ex. 1163 ¶ 49 (citing Ex. 1005, 1–3). Dr. Bajaj’s testimony is unrebutted, credible, and supported by the record. We agree with Dr. Bajaj’s reasoning, which is based on direct quotes in Menon. We further agree with Dr. Bajaj’s conclusion that Menon does not teach away from the combination with Trefethen. Id. ¶¶ 50–52. Menon’s description of building on and enhancing the teachings of Trefethen—the earlier work of the same research group at Cornell—by adding MEX routines to achieve high-performance parallel computing and extensibility for MATLAB, demonstrates a classic motivation for a POSITA to combine the teachings of Menon and Trefethen. RS6000 and POEref are specifically referenced in Menon-Trefethen and add operational details of the parallel operating platform that teach a POSITA how to implement the MultiMATLAB system with a reasonable expectation of success. Such facts are inconsistent with Patent Owner’s teaching away and lack of motivation arguments.” slip op. at 24

Resp. 11–12, 21; see also Ex. 1163 ¶ 22 (“The claim does not recite ‘single chip,’ ‘single package,’ ‘single die,’ or ‘single multi-core microprocessor.’”). Nor do the claims recite a plurality of processing cores “within” a single-chip package or read as “multi-core within a processor” as argued by Patent Owner. Resp. 12–14; Sur-Reply 2; see Reply 6 (citing Ex. 1163 ¶ 23 (“Thus, the phrase ‘with a plurality of processing cores’ identifies the required processing resources associated with the hardware processor; it does not import a packaging limitation.”)). 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. Processor cores are generally independent microprocessors, but more than one can be included in a single-chip package.” Id. at 1212 (partially quoting Ex. 1001, 5:11–16); Sur-Reply 2. The quoted description does not support Patent Owner’s contention that the claimed “a . . . hardware processor with a plurality of processing cores” must be limited to a “single multi-core processor” that “locates multiple cores within a ‘single-chip package,’” i.e. limited to a single multi-core microprocessor such as “a Core 2 Duo is one processor package with two cores.” Resp. 12– 13, 21 (citing Ex. 1001, 7:15–25). The description quoted above from column 5, moreover, describes a “processor” that “can contain one or more processor cores” each of which can be an independent microprocessor. Reply 2–3 (citing Ex. 1001, 5:11–16; Ex. 1163 ¶¶ 10–14). As Petitioner emphasizes, the specification distinguishes a “processor” from a “microprocessor” and describes a “processor” that “can be one or more general purpose single-core or multi-core microprocessors,” rather than limiting a “processor” to a single multi-core microprocessor.

    “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. Menon is intended to be read in conjunction with Trefethen, as would be expected from two references generated by the same research group at the same university addressed to the same technical subject matter about a year apart. Ex. 1005, 1; Ex. 1006, Ex. 1086 ¶¶ 65, 101, 102. The very first citation in Menon is to Trefethen. Ex. 1005, 2, 16.” slip op. at 30

Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). The fact that a limitation in the specification may define over the prior art does not justify importing that limitation into the claims unless a term is expressly defined such that the patentee becomes his own lexicographer or there is an express disavowal of claim scope. See GE Lighting Sols., LLC v. AgiLight, Inc., 750 F.3d 1304, 1308–09 (Fed. Cir. 2014). There is no evidence of an express disavowal here. As to lexicography, we disagree with Patent Owner’s contention that the Specification defines the phrase “first driving mode.” Patent Owner relies on the mere fact that the specification describes an embodiment with a first driving mode that has a low frequency driving signal and is in a “double-ended” configuration, but this is not sufficient to define the term. The specification does not require that a low frequency driving signal must necessarily be used. In fact the specification, although not entirely clear, suggests that the driving signal may be from a high frequency ballast. Ex. 1001, 51:8–14. Thus, the fact that the patent here discloses a low frequency driving signal does not mean that all the claims are directed to such a driving signal. See E-Pass Tech., Inc. v. 3Com Corp., 343 F.3d 1364, 1368–69 (Fed. Cir. 2003). Indeed, dependent claim 15 recites “the first driving mode is performed when the external driving signal is a relatively low frequency or voltage signal,” while the independent claims were directed to a more general driving signal. The doctrine of claim differentiation suggests that the independent claims here should not include explicit limitations of a dependent claim. See Phillips, 415 F.3d at 1315 (“[T]he presence of a dependent claim that adds a particular limitation gives rise to a presumption that the limitation in question is not present in the independent claim.”); Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 910 (Fed. Cir. 2004).” slip op. at 7
