      “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. Instead, we assess Dr. Doolittle’s testimony on a case-by-case basis as discussed below.” slip op. at 21

      “lower wavelength might offer, there were other drawbacks that a person of ordinary skill would have to balance. But “a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.” Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). Indeed, Petitioner has shown several references—including, Basin-2005, Shimizu, and Stokes—that made this tradeoff. Moreover, “[o]bviousness does not require absolute predictability of success. . . . [A]ll that is required is a reasonable expectation of success.” In re O’Farrell, 853 F.2d 894, 903–04 (Fed. Cir. 1988). We find that the prior art of record demonstrates that a person of ordinary skill in the art at the time of the invention would have such an expectation in making the combination of Basin-2007 and Basin-2005. Accordingly, we find that Petitioner has shown by a preponderance of the evidence that there would have been motivation to combine Basin-2007 and Basin-2005 with a reasonable expectation of success.” slip op. at 41

      “Under 35 U.S.C. § 324(a), a post-grant review may be instituted only if “the information presented in the petition . . . demonstrate[s] that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” Post-grant review is available for patents that issue from applications that at one point contained at least one claim with an effective filing date on or after March 16, 2013. See Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”), §§ 3(n)(1), 6(f)(2)(A). After considering the briefing and the evidence of record, for the reasons set forth below, we determine that Petitioner has shown that the ’947 patent is eligible for post-grant review, and has shown it is more likely than not that at least one challenged claim of the ’947 patent is unpatentable under § 324(a).

Patent Owner did not file a Preliminary Response to the Petition and, therefore, at this point, does not contest Petitioner’s definition for one of ordinary skill in the art. Petitioner’s proposed definition appears to be consistent with the disclosure of the ’947 patent, and we adopt it for purposes of this Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “Having considered the record, we determine that no express claim construction is necessary for any claim terms for the purposes of rendering a decision to institute trial. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (holding that only claim terms in controversy need to be construed, and only to the extent necessary to resolve the controversy (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). At this stage, we find it unnecessary to resolve whether “electronic control unit” and “processing module” should be construed as mean plus function limitations under § 112(f), because it is possible to address the obviousness grounds presented whether or not these limitations are so construed, and even if the claims were indefinite in the manner Petitioner contends. See Intel Corp. v. Qualcomm Inc., 21 F.4th 801, 813 (Fed.

Patent Owner argues that Armitage does not monitor all of the axes, like the ’915 patent. See Sur-reply 1–3. However, the ’915 patent, just like in Armitage, isolates the data from a single axis for further analysis. See Ex. 1001, 13:17–24. Thus, we do not find Patent Owner’s distinction to be persuasive.

      “B. Level of Ordinary Skill in the Art Petitioner contends that: A person of ordinary skill in the art at the priority date for the ’274 Patent (“POSITA”) would have had a bachelor’s degree in electrical or computer engineering, or a closely related scientific field such as physics or computer science, and two years of work experience with video processing. A lack of experience can be remedied with additional education (e.g., a Master’s degree), and likewise, a lack of education can be remedied with additional work experience (e.g., 4–5 years). This definition would apply at the earliest claimed priority date of the ’274 Patent as well as any later date. Pet. 12 (citing Ex. 1005 ¶¶ 50–52).

      “For the reasons that follow, we determine that the ’928 application does not provide sufficient written description support, for at least independent claim 1 of the ’274 patent, so as to “reasonably convey[] to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date” of the ’928 application. Ariad, 598 F.3d at 1351. Accordingly, we are persuaded that the ’928 application lacks sufficient written description support for the invention recited in claim 1 of the ’274 patent, and thus, claim 1 does not receive an effective filing date as early as that of the ’928 application (i.e., December 23, 2010). We further determine that Petitioner filed the Petition within the 9-month statutory period for requesting post-grant review in accordance with 35 U.S.C. § 321(c). The ’274 patent issued on September 14, 2021 (see Ex. 1001, code (45)), and the present Petition was accorded a filing date of June 9, 2022 (see Paper 5). Accordingly, the Petition was filed less than 9 months after the date of issuance of the ’274 patent.

      “Id. at 7:24–8:4 (emphasis added). The ’928 application repeatedly makes clear that directionality and intra mode are related, but distinct concepts. They are not interchangeable as Patent Owner argues. On this point, we find Dr. Freedman’s explanation in paragraph 85 of his Declaration on the relationship between “intra mode” and “directionality” to be particularly well-reasoned and persuasive. As Dr. Freedman explains, [t]hroughout the ’928 application, the text uses the term “directionality” to refer to characteristics of neighboring blocks, whereas the term “intra mode” is used when referring to the current block. For example, the ’928 application describes that “directionality” of neighboring blocks is “estimated from the neighboring blocks” that “have already been reconstructed” while the “intra mode” is selected for the current block for purposes of reconstructing that current block. This is likely because the neighboring blocks “have already been reconstructed” and thus, the intra mode number that was used in reconstructing those blocks is no longer pertinent. Instead, what is pertinent in the ’928 application’s method is the directionality characteristic of those neighboring blocks. Phrased differently, in the ’928 application, directionality is a concept that is evaluated after performance of intra prediction (i.e., after reconstruction), whereas the intra mode or number is a concept used during performance of intra prediction. They are not equivalent in the context of the ’928 application. Ex. 1005 ¶ 86 (citing Ex. 1028, 11:14–12:4, 25:10–15; Ex. 1036, 706 (“The DCT coefficients gathered from the MPEG 2 process are used to estimate the directional features in a picture. The estimated directional features are then used to compute the intra prediction modes in the H.264 encoding stage.”)).8 Thus, we are persuaded by Dr. Freedman’s testimony, supported by Kalva, that these terms are not synonymous, as is Patent Owner’s and its expert’s position.” slip op. at 31

Ex. 1003 ¶ 144 (citing Ex. 1006, 14:65−15:1). We agree with and credit Dr. Houh’s testimony, and we find that such an artisan of ordinary skill would have understood that, in Eyal in combination with Wiser, the voucher ID provided in the play-list is uniquely associated with the client device and a viewing session of the media. Ex. 1003 ¶ 151 (citing Ex. 1006, 8:30−33, 15:23−28). We do not agree with Patent Owner’s assertion that “Wiser teaches away from video.” PO Resp. 33 (citing Ex. 2012 ¶ 174). “A reference may be said to teach away when a person of ordinary 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). Here, nothing in Wiser would discourage a relevant artisan from applying its teachings to video media, as Patent Owner alleges. Patent Owner’s argument of teaching away is based on speculation. As discussed above, Wiser’s disclosure is not limited to audio media. Ex. 1006, 1:5−8, 1:23−26, 3:8−10; Ex. 1083, 145:20−147:21. The “mere disclosure of alternative designs does not teach away.” In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Moreover, KSR instructs us that “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize 20 that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417. As Dr. Houh testifies, “[s]ervers’ limited streaming capacity was a common media delivery problem, and well-known solutions existed before the ’360 Patent, including generating a reservation to ensure resource availability for streaming media to the user.” Ex. 1003 ¶¶ 106, 167 (citing Ex. 1019, 263 (Discussion on Resource Reservation Protocols (RSVP) in the book entitled “Communication and Computing for Distributed Multimedia Systems”); Ex. 1023 (RSVP Specification); Ex. 1024, 194 (Discussion on the Reservation Protocol in the book entitled “Multimedia Servers”)).” slip op. at 20

Patent Owner cites the specification and Mr. Adam’s testimony 13 for support. Id. (citing Ex. 1001, 10:33−37; Adams Decl. ¶ 110). Mr. Adam relies on the ’636 patent specification, which states that “[a] reservation is a feature that enables the streaming system 102 to reserve system resources, such as switches, processors, or media, either now or in the future, to ensure a quality media experience.” Ex. 1001, 10:33–37. Further, “[t]he reservation uniquely identifies the viewer 118 or 120 and the customized play script.” Id. at 10:27–28, 10:34–37.

      “in our Decision on Institution. In the Decision, we directly addressed Patent Owner’s arguments that Dr. Baker is not qualified to testify in this proceeding because he is neither a person of ordinary skill in the art, nor an expert in the relevant art. See Dec. 7–8. In particular, we explained that there is no requirement “that the expert’s experience perfectly match the relevant field, or that the expert is a person of ordinary skill in the art.” Id. at 7. We also explained that Dr. Baker testifies as to his education and qualifications and provides his curriculum vitae. See Ex. 1002 ¶¶ 3–12; Ex. 1003. At this preliminary stage, we cannot say that Dr. Baker’s scientific, technical, and other specialized knowledge will not be helpful in understanding the evidence. See Fed. R. Evid. 702(a). On this record, we are not persuaded that Dr. Baker’s testimony should be disregarded. Id. at 8. Therefore, even if Dr. Baker were not a person of ordinary skill in the art as Patent Owner contends, it does not follow that he is unqualified to testify in these proceedings. Nothing was misapprehended or overlooked in considering Dr. Baker’s testimony.” slip op. at 6

      “(Ex. 2001). In the Preliminary Response, Patent Owner cited the Konda Declaration when discussing the experience and qualifications of the named inventor of the ’523 patent. Prelim. Resp. 8–9. The education level of the inventor, however, is just one of several factors that we may consider in determining the level of ordinary skill in the art. See Daiichi Sankyo Co., Ltd. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007) (enumerating six factors that “may be considered in determining the level of ordinary skill in the art” (quoting Evt’l Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696 (Fed. Cir. 1983))). And, as Patent Owner noted in the Preliminary Response, “these factors are merely a guide to determining the level of ordinary skill in the art.” Prelim. Resp. 7–8 (citing Daiichi Sankyo, 501 F.3d at 1256). In any event, in the Decision we also considered Petitioner’s and Patent Owner’s proposed definitions of the level of ordinary skill in the art, noted the differences between them, and stated that “[o]ur determination regarding Petitioner’s challenge does not turn on the differences between Petitioner’s and Patent Owner’s definitions.” Dec. 7. Therefore, our evaluation of Petitioner’s challenges and Dr. Baker’s testimony in support thereof would have been the same under Petitioner’s and Patent Owner’s proposed definitions of the level of ordinary skill in the art. See id. (“[W]e note that our conclusions would be same under either definition.”).” slip op. at 7

      “Moreover, in the Decision, we directly addressed Patent Owner’s argument with respect to whether the ’394 provisional and ’605 PCT provided support for the claim limitation “said routing network comprising a plurality of stages y, in each sub-integrated circuit block, starting from the lowest stage of 1 to the highest stage of y, where y≧1” when y=1. Dec. 14. In particular, we found that Patent Owner’s arguments, as we understand them, are directed only to the disclosure of a network with only one stage (y=1). [Prelim. Resp.] at 15–39. Patent Owner does not address the other limitations of claim 1, and does not point to any disclosures in the priority applications that describe a sub-integrated circuit block with only one stage that also comprises pluralities of forward connecting links and backward connecting links as required by claim 1. Id. Thus, we did not overlook Patent Owner’s arguments, but rather evaluated the disclosures in the ’394 provisional and ’605 PCT and determined, on the record at this stage of the proceeding, that they do not provide sufficient written description support for the challenged claims. The parties will have the opportunity to further develop the record on these issues during trial, and the Board will evaluate the fully-developed record at the close of the evidence. D.

      “We agree with Petitioner and determine that a POSA would have been a person having a general knowledge about, and experience with, expandable containers, including, without limitation, balloons, and at least an associate’s degree in mechanical engineering, or the equivalent. This level of skill is consistent with the types of problems and solutions described in the ’612 patent and cited prior art. For example, the ’612 patent describes a fluid inflatable system that uses elastic valve 20A (e.g., mechanical gasket, O-ring, etc.) for sealing fluid inside multiple containers (e.g., water balloons). See Ex. 1001, 1:22–24, 3:10–16. In any event, none of the issues in this case turn on the definition of a POSA, and the prior art of record provides ample evidence of the level of skill in the art. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (finding that the Board of Patent Appeals and Interferences did not err in concluding that the level of ordinary skill was best determined by the references of record); see also Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

    • Disclosure Requirements (§112) › Definiteness (Nautilus)IndefiniteNot shown unpatentable

      “While the terms “unfilled state” and “filled state” describe the fullness for a container, we do not agree with Petitioner that the claim language requires determining the precise amount of fluid for each state. Section 112(b) requires that we read claim terms in the context of the surrounding claim language, not in isolation. Telebrands, 733 F. App’x at 1020. When we look at the entire claim phrase—“regardless whether the first and second ones of the plurality of containers are in a filled state or an unfilled state”— the plain language is clear that regardless of whether the balloons are in either state, the “at least first and second ones of the plurality of containers are disposed sufficiently close to each other such that they press against each other.” In other words, the exact volume of fluid or water needed to reach a “filled state” does not need to be determined in order to understand the metes and bounds of the claim so as to understand how to avoid infringement. We are further persuaded because this is consistent with the district court’s construction of this term. See Ex. 1023, 19–20.” slip op. at 17

    • Disclosure Requirements (§112) › Written description (Ariad)Written description adequateNot shown unpatentable

      “Based upon our review of the specification, and consideration of the arguments and evidence presented, Petitioner’s position is not persuasive. We agree with Patent Owner that Petitioner has failed to show that the ’612 patent does not provide such adequate guidance to a person of ordinary skill in the art. On its face, Figure 1 of the ’612 patent (reproduced below) shows containers 18 in contact or pressing against one another with the reasonable clarity required by Vas–Cath Inc. Figure 1 of the ’612 patent is reproduced above. Although the ’612 patent describes, as Petitioner notes, that tubes 16 can be different lengths, we are not persuaded that the ’612 patent’s disclosure of an embodiment with different tube lengths detracts from the concurrent disclosure in Figure 1 of an embodiment, where it is difficult to describe containers 18 as being not in contact with each other. Additionally, we agree with Patent Owner that Petitioner has failed to show adequately that a person of ordinary skill would not have understood the ’612 patent as describing the containers in Figure 1 as pressing against one another in an unfilled state. The ’612 patent indicates Figure 1 shows elastic valve 20A in an open configuration when container 18A is attached to tube 16A to allow container 18A to fill with fluid. Ex. 1001, 3:14–18. In this open configuration, container 18A is to be filled with fluid, after which, “it may be removed from tube 16A, whereupon elastic valve 20A closes, thereby closing the neck of container 18A and sealing the fluid inside.” Id. at 3:18–21 (emphasis omitted). The ’612 patent refers to Figure 1 to describe an embodiment where elastic valve 20A is in an open configuration to fill a container that has not been filled (i.e., unfilled) and removed from tube 16A. Thus, we are persuaded that, at least, Figure 1 and this accompanying description of Figure 1 in the ’612 patent provides sufficient written description for the recited limitation that “at least first and second ones of the plurality of containers are disposed sufficiently close to each other such that they press against each other . . . in a filled state or an unfilled state.”” slip op. at 21
