    “Petitioner argues that at the relevant time of the invention claimed in the ’849 patent (April 2005),2 a person of ordinary skill in the art would have had “at least a bachelor’s degree in computer science, computer engineering, electrical engineering, or an equivalent field requiring learning computation principles, and two years of work experience in networking or streaming media systems, particularly audio and video, over the Internet,” where “[a]dditional education could compensate for less practical experience and vice versa.” Pet. 5–6 (citing Ex. 1002 ¶¶ 18–23). In the Decision on Institution, the Board agreed with and applied Petitioner’s proposed definition. Dec. on Inst. 9–11. Patent Owner proposes a very similar definition of “a bachelor’s degree in electrical engineering, computer engineering, computer science, or a related field, and two to three years of experience in the design or development of (1) video processing systems, audio processing systems, and/or the equivalent; and (2) networking and communications systems, or the equivalent,” where “[a]dditional graduate education could substitute for professional experience, or significant experience in the field could substitute for formal education.” PO Resp. 23 2 Petitioner states that it “uses [the earliest possible priority date of April 18, 2005] as the priority date of the challenged claims.” Pet. 6. Patent Owner agrees that the “earliest effective filing date” of the challenged claims is April 18, 2005. PO Resp. 19. The ’849 patent is expired.

    “Finally, Petitioner explains in detail why and how a person of ordinary skill in the art would have had reason to combine the teachings of Carmel and Mattavelli, with a reasonable expectation of success. See Pet. 50–55. Specifically, an ordinarily skilled artisan would have modified Carmel’s system to use “Mattavelli’s CGD techniques to optimize the decoding of in more efficient network bandwidth usage and improved playback of multimedia data streams. Id. at 50, 52–53, 55. Petitioner contends that Carmel and Mattavelli are both directed to processing multimedia data playback “for the appreciation of a user,” while providing the highest perceived audio and video output quality possible in view of system constraints to ensure playback continuity. Id. at 50–51 (citing Ex. 1003, 7:35–49, 10:48–54, 11:9–18, Figs. 3D, 6B; Ex. 1004, 2309–10). Petitioner argues that Carmel and Mattavelli both pertain to compression of multimedia data using well-known coding and compression standards for video streaming. Id. at 51 (citing Ex. 1003, 7:25–26, 11:24–52; Ex. 1004, 2309–11). Petitioner further asserts that a person of ordinary skill in the art would have appreciated that Carmel and Mattavelli “complement[]” each other because Carmel addresses constraints on available network bandwidth and Mattavelli addresses limits on available processing resources at the client/multimedia player. Pet. 52 (citing Ex. 1003, code (57), 7:36–41; Ex. 1004, 2309–2312). According to Petitioner, an ordinarily skilled artisan would have been motivated to combine the complementary teachings in Carmel and Mattavelli to create a more robust streaming system that addresses both bandwidth constraints and client processing limits to provide the best possible playback experience. Id. (citing Ex. 1002 ¶¶ 212–215). Petitioner also contends that Mattavelli teaches that merely optimizing transmission bandwidth is not sufficient and is potentially harmful, which provides an express motivation to combine Carmel’s and Mattavelli’s complementary teachings to ensure that different, related links in the streaming playback chain are optimized together. Id. at 53 (citing Ex. 1002 express disclosure that would have motivated a person of ordinary skill in the art to incorporate Mattavelli’s complementary teachings regarding decoding because Carmel states that multimedia playback is achieved “preferably with only a minimal necessary transmission and decoding delay.” Id. at 53–54 (quoting Ex. 1003, 10:50–54; citing Ex. 1002 ¶ 218). Patent Owner in its Response does not dispute that Carmel and Mattavelli teach the preamble and limitations 1[a.i]–1[c.i], or that a person of ordinary skill in the art would have been motivated to combine the references’ teachings in the manner asserted by Petitioner.6 Nonetheless, the burden remains on Petitioner to demonstrate unpatentability.

    “In response, we conclude that the most natural reading of limitation [l] results from examination of the entire limitation: “locating encryption information that identifies encrypted portions of frames of video within the requested portions of the selected stream of protected video.” Ex. 1001, 27:54–57. The “within” most naturally connotes where the encrypted portions of frames of video occur, as opposed to determining where the encryption information may be located. Patent Owner’s interpretation is not wrong, i.e., the limitation could be read as Patent Owner suggests, leading to a narrower construction, but we are not persuaded that the construction of limitation [l] must be so limited, on the basis of the words themselves. We continue to reject Patent Owner’s interpretation that limitation [l] requires locating encryption information within the requested portions of the selected stream of protected video. See Inst. Dec. 27–30; 1st Final Dec. 8. Although it is apparent that encryption information can be found within the requested portions, we are not persuaded that the claim language or ’588 Patent implicitly or explicitly requires such a relationship. Likewise, although embodiments disclosed in the Specification of the ’588 Patent are consistent with Patent Owner’s more restrictive construction, the Specification also is consistent with the more grammatically correct construction as well. Thus, we construe limitation [l] as requiring that the encrypted portions of frames of video be within the requested portions of the selected stream of protected video, but we do not construe limitation [l] as requiring that the encryption information be within the requested portions of the selected stream of protected video.” slip op. at 15

    “We agree with Petitioner and determine that the construction of “relational references” does not require the use of a relational model and, further, includes pointers that point to related messages exchanged among users. The intrinsic evidence leads us to this construction. First, the relevant language of claim 1 recites “a message container containing relational references pointing to a plurality of sent submessages stored externally to the message container in the message database.” Ex. 1001, 15:56–59. A relational model is not recited in that language or anywhere else in the claim. See id. at 15:51–16:14. Therefore, the claim does not expressly require a relational model. Furthermore, the claim language supports Petitioner’s interpretation that “relational references” include pointers that point to related messages because the claim states that the “relational references” perform the task of “pointing to a plurality of sent submessages.” Pet.

    “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

    “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.

    “We find credible and agree with Dr. Cooklev’s testimony that the predistortion signals from tables 17-1 and 17-2 “are cancelled out by Suzuki’s amplifier” 28. Ex. 2013 ¶ 50. Dr. Cooklev supports his opinion by referring to paragraph 1 of Suzuki, which states that Suzuki’s invention is directed to “a multi-band lookup table type predistorter” (such as the one implemented using lookup tables 17-1 and 17-2 in Figure 6) that “compensates for a distortion of a power amplifier.” Ex. 2013 ¶ 54; Ex. 1004 ¶ 1. Dr. Cooklev’s opinion is also supported by paragraph 3 of Suzuki, which explains that a conventional digital predistorter uses a lookup table “for linearizing non-linear characteristics of an amplifier.” Ex. 1004 ¶ 3; Ex. 2013 ¶ 54. Dr. Cooklev further supports his opinion by relying on Suzuki’s disclosure in paragraph 46 that power amplifier 28 is “subject to distortion compensation” by the predistorter, and that distortion components in the signal output by the amplifier are canceled by “distortion compensation data [that] are read out from the lookup tables 17-1 and 17-2 and provided to the adders 13-1 and 13-2, respectively.” Ex. 1004 ¶ 46; Ex. 2013 ¶ 54. And, Dr. Cooklev’s opinion is supported by Suzuki’s disclosure in paragraph 47 that the distortion compensation added by adders 13-1 and 13-2 add the distortion compensation data from lookup tables 17-1 and 17-2 “to perform distortion compensation (addition of predistortion)” to “signals to be transmitted.” Ex. 1004 ¶ 47; Ex. 2013 ¶ 54. Petitioner agrees that the distortion compensation data from lookup tables 17-1 and 17-2 “are added to the respective frequency band from” input signal ST “in order to predistort the output signal, which is then transmitted,” and does not dispute that the distortion compensation data from lookup tables 17-1 and 17-2 is ultimately cancelled out by the distortion created by amplifier 28. Pet. Reply 8. In light of the above evidence, we agree with Patent Owner that Suzuki’s distortion components from lookup tables 17-1 and 17-2 in Figure 6 (which Petitioner relies on for the first and second digital signals in limitations 10a and 10b) are cancelled out by the distortion created by power amplifier 28 before the signal is ultimately transmitted. We agree with Petitioner that these first and second digital signals include data in the form of distortion compensation data. However, because these signals are cancelled by the distortion from amplifier 28 before transmission, the data from these signals is never transmitted. Thus, the first and second digital signals identified by Petitioner (the distortion compensation data from lookup tables 17-1 and 17-2) do not comprise data “to be transmitted,” as limitations 10a and 10b require.” slip op. at 35
