“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.

The Petition contends that a POSITA would have been motivated to combine the teachings of POEref with Menon “because Menon suggests the combination by teaching that MultiMATLAB uses ‘POE, IBM's Parallel Operating Environment.’” Id. at 26–27 (citing Ex. 1005, 6); (further citing Ex. 1003 ¶¶ 150–153; Ex. 1005, 14; Ex. 1008, 11, 46). We agree with Petitioner’s analysis.

“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
