      “Kwatra teaches, at Equation 7, minimizing velocity and acceleration of a function representing camera path (P). FF ¶¶ 6, 8–9. Kwatra does not state that this camera path function considers rotation. Rather, the words “camera path” suggest x, y, z movement of the camera rather than rotation of the camera. Dr. Foroosh’s testimony that Kwatra’s minimization of a smoothed camera path does not result in minimizing rotational velocity and acceleration is credible because this testimony is consistent with Kwatra as a whole and consistent with the other evidence of record. Id. ¶ 10. Kwatra recognizes that image rotation angle (“θ”) may not remain smooth. Id. ¶ 12. But rather than attempting to minimize velocity and acceleration of rotation of the camera housing, Kwatra states that applying a smoothness constraint on rotation angle “may be non-linear.” Id. ¶ 13. Consistent with Kwatra, Dr. Foroosh credibly explains the difficulty of applying linear techniques to rotation. Id. Thus, Kwatra proposes instead constraining the sine and cosine of theta. Id. ¶ 14. The Kwatra provisional application is part of the Kwatra reference (id. ¶ 15), and it similarly opts for simpler schemes rather than estimating all parameters for all frames jointly. Id. ¶ 16. The provisional explains that the rotational component is relatively small such that non-linear computations minimizing velocity and rotation can be avoided. Id. ¶¶ 17–18. The testimony of Patent Owner’s witness, Dr. Foroosh, explaining the provisional is credible (Ex. 2018 ¶ 72) because it is consistent with Kwatra’s complete disclosure. Dr. Foroosh’s testimony is more credible than the testimony of Petitioner’s witness, Dr. Katsaggelos, because Dr. Katsaggelos did not review the Kwatra provisional application and, thus, did not review the entire disclosure of Kwatra.

      “4. Conclusion for the Prior Art Analysis In sum, we find that Zhou does not disclose the low-light high-pass parameter or the stickiness parameter. Petitioner’s grounds for both independent claims 1 and 16 rely on Zhou for teaching a low-light high-pass parameter or a stickiness parameter. Pet. 23–28, 64. Because we find Zhou does not teach these limitations, all of Petitioner’s grounds fall for this reason. III.

      “We review this testimony based on the strength of the underlying factual basis. 37 C.F.R. § 42.65(a); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value . . ..”). Here, the underlying factual basis is not very strong for either witness. That said, we find that Dr. Foroosh’s testimony is more logically sound and consistent with the ’840 patent disclosure. Based on our reading of the specification, we find a clear indication that “stickiness” has to do with the past. In order to control “the extent by which preceding portion(s) . . . impacts determination of the smoothed trajectory” (emphasis added), one must control the degree by which the past frames impact determination. And to control the degree of the past’s influence, one must, as a consequence, favor the past over the future. That is, the frame of reference of the stickiness parameter is the past. The specification could have used a time-agnostic term, like a “nearness” or “adjacency” parameter, but it did not. Thus, the fact that “stickiness” is used in conjunction with “preceding” indicates that it deals with a preference for preceding frames. On this basis, we find Dr. Katsaggelos’s testimony less persuasive than Dr. Foroosh’s.” slip op. at 10

      “That said, we do not construe a stickiness parameter as prohibiting consideration of future frames. Instead, we determine that the stickiness parameter’s value determines the impact of the preceding portions, versus the following portions. The ’840 patent recognizes this, when it says that a stickiness parameter value of “1,” representing a “lazy” stabilizer that maximally favors the past, would not override a violation of the margin constraint based on the look-ahead (i.e., would not allow the viewing window to fall out of bounds in the event of large future motion). See Ex. 1001, 22:26–30; see also id. at 12:61–13:29 (acknowledging that favoring the past may lead to a conflict with the viewing window determination), 15:39–60 (adjusting the viewing window to ensure it does not violate a margin constraint). Thus, while a past-favoring parameter by necessity favors the past over the future, it does not prohibit consideration of the future. In view of the above, we construe the claimed “stickiness parameter” as a parameter that controls the extent by which preceding portions of the trajectory impacts determination of the smoothed trajectory, with an understanding that in order to favor preceding portions, to some extent, the parameter must relatively disfavor following portions.” slip op. at 10

      “Given the teachings of the specification, we agree with Patent Owner that a low-light high-pass parameter is a parameter of a smoothing function that favors high frequencies (high pass) when exposure times are long (low light). See Tr. 42:10–18 (Patent Owner’s counsel stating that “high-pass” means “there’s a bias or preference for high frequencies”); Ex. 2020, 93:23– 94:15 (Petitioner’s declarant, Dr. Katsaggelos, agreeing that a high-pass system attenuates the low frequency of a signal). Although we acknowledge Petitioner’s position that the specification provides other ways or considerations in implementing a smoothing function, based on our above analysis of the specification, we find that the specification describes the lowlight high-pass parameter as a specific component of a smoothing function. See, e.g., Ex. 1001, 21:17–25 (setting out several parameters besides the low-light high-pass parameter used in trajectory smoothing).” slip op. at 10

      “position and a real device position. Id. at 18:27–40. In other words, the blur is addressed by analyzing the image to identify motion and then shifting the image. Shi, however, does not disclose how its parameter is based on low light (or the long exposure times indicative of low light). In its Petition, Petitioner asserts that a person of ordinary skill in the art would understand that “blurs can be caused by low light conditions.” Pet. 28 (citing Ex. 1003 ¶ 111). Although this is true, that does not mean that Shi’s blurs are identified by a parameter that considers low light. As we just described, Shi identifies the blur by quantifying the amount of motion of the points in an image, not by identifying low light. This is simply a different way to determine the presence of motion blur. In Shi, blur is measured, whereas in the ’840 patent, it is inferred based on low-light conditions (e.g., by observing the exposure time). See, e.g., Ex. 1007, 18:7– 26; Ex. 1001, 19:12–26. In its Reply, Petitioner does not point to any further disclosures. Accordingly, we find that Shi does not disclose the “low-light” aspect of the claimed low-light high-pass parameter. This is sufficient to determine that Petitioner’s ground does not meet all claim limitations. Similarly, we find that Shi does not disclose the “high-pass” aspect of the parameter. Shi’s blur compensation uses a spherical interpolation to modify the image. Ex. 1007, 18:27–40. The low-light high-pass parameter, as we have construed the term, allows more high frequencies. To allow more high frequencies, this necessarily means either allowing fewer low frequencies, or allowing more high frequences as opposed to some counterfactual situation in which fewer high frequencies were going to be allowed. See Ex. 2020, 94:23–95:15; Ex. 2022. We are directed to no persuasive evidence from Petitioner that Shi’s spherical interpolation favors high frequencies over low frequencies. Accord Ex. 2018 ¶ 107 (Patent Owner’s expert stating that Shi’s spherical interpolation “reintroduce[es] both high- and low-frequency motion”). Even if Shi allows the viewing window to track the camera position “consistent with the natural blur in the image” (Ex. 1007, 17:63–67), we are not provided with sufficient evidence to conclude by a preponderance of the evidence that providing a similar visual goal as a high-pass parameter (Ex. 1001, 22:16–18, “the output motion may include high frequencies that mask motion blur”) is the same as having a high-pass parameter. Again, merely preserving high frequencies is not the same as having a “high-pass parameter” because, as construed, a “high-pass parameter” also involves some degree of attenuation of low frequencies or relative increase of high frequencies. Accordingly, we find that Shi does not disclose the “high-pass” aspect of the claimed low-light high-pass parameter.” slip op. at 18

      “We agree with Patent Owner that the recited second type SIBs exclude first type SIBs. The plain meaning of “first type” and “second type” indicates that the first type and second type are different in kind. RMTA 22 (App. A). Our interpretation is consistent with the Specification, which explains that second type SIBs exclude first type SIBs. As Patent Owner points out, the ’958 patent discloses “first type of system information (1TYP SIB) is . . . essential . . . for initial system access” and “second type of system information (2TYP SIB) is nonessential system information . . . defined as all other types of information, and thus excludes the [] information required for initial access.” Id. at 11–12 (citing Ex. 1001, 8:34– 46); see also Ex. 1001, Abstract (interchangeably using the terms second type and non-essential). Despite Petitioner’s argument that this disclosure is non-limiting and directed to a disclaimed example embodiment (Opp. 8–9), Petitioner could not identify any embodiment, among the approximately forty disclosed embodiments, describing something other than the first type SIB being essential information and the second type SIB being non-essential information. Tr. 22:18–26. Even the Petition acknowledges that “the ’958 Patent further classifies a second type of system information, the ‘non-essential’ SI, which is defined as all other types of information excluding that first type of information required for initial access.” Pet. 5. Furthermore, the prior art of record suggests that a person of ordinary skill would have understood second type SIBs exclude first type SIBs. See Ex. 1008 ¶ 48 (describing two categories of system information, “essential SI” and “Other SI”). Patent Owner’s expert also understood the recited first and second type SIBs as being mutually exclusive. See Ex. 1011, 49:10–13. For the above reasons, we do not agree with Petitioner that the recited second type SIB lacks any requirements, nor do we interpret claims 7 and 8 such that the first type SIB could be a second type SIB.” slip op. at 19

      “(d) Limitation 7h: Analysis We agree with Patent Owner that Petitioner’s arguments with respect to limitation 7h are insufficient because they fail to address the limitation as written and improperly incorporate previous arguments by reference. For example, Petitioner did not map the recited “group identifier” when opposing Patent Owner’s Revised Motion to Amend. See Opp. 16–17. In its Sur-reply, Petitioner contends that limitation 7h’s requirement of transmitting the group identifier was previously “set out in Patent Owner’s prior papers,” but does not refer to any specific papers or exhibits. Pet. Surreply 11–12. We decline to search for and piece together Petitioner’s arguments and evidence to develop a persuasive theory of unpatentability. See 37 C.F.R. section 42.6(a)(3). Petitioner similarly failed to address adequately where Lee discloses or suggests the recited “compressed format” and “plural parameters.” See Opp. 16–17. Aside from the above concerns, we also do not see sufficient explanation with respect to limitation 7h’s requirement that the transmitting by broadcast be based on a comparison of the value tag. Petitioner argues that, because Patent Owner does not dispute limitation 7g, “it would have been obvious to a POSITA to use the same value tag[] to determine the system information broadcast in Lee’s compressed format embodiment.” Pet. Sur-reply 12. This conclusory statement is not supported by any citations to evidence and was improperly introduced in the Sur-reply. Moreover, whether it was obvious to determine what system information is broadcast is not commensurate with the claim scope because limitation 7h requires that the broadcasting (not the broadcast content) be based on a comparison of the value tag.

      “the gap between the playback deadline and the target schedule, (td(n) − tT(n)), is the target buffer duration, i.e., ‘the desired client buffer duration (in client time).’” Id. at 22–23 (quoting Chou ¶ 74). Petitioner also argues that “in efforts to match upper bound tb(n) to target schedule tT(n), Chou takes into consideration the time duration between target schedule tT(n) and the playback deadline td(n).” Thus, it appears Petitioner assembles three separate and distinct time intervals from Chou’s timing diagrams and equations to construct one contiguous time interval equivalent to claim 1’s remaining time. However, Chou does not recognize the time interval that Petitioner posits, and Petitioner has not persuasively shown that this combined time interval exists as a teaching in the prior art and is used as part of any step or decision involved in determining the code rate. As admitted by Petitioner’s expert, Dr. Reader, Petitioner’s analysis “used the claims as a road map to find limitations in the prior art.” Ex. 2015, 76:4–9 (Reader Deposition Transcript). See also Tr. 28:20–31:2 (Petitioner’s response to whether identification of and integration of separate time ranges described by Chou is hindsight reconstruction, Petitioner argues Chou’s device operates such that code rate is based on remaining time). Under the circumstances, this is improper because Petitioner and Dr. Reader do not justify this combination of separately identified time ranges except based solely on hindsight reconstruction of the claimed invention. However, even if that were not the case, we are not persuaded that Chou or the other asserted prior art references suggest using the combined time interval td(n) − ta(n) as the basis for any decision related to determining the code rate.” slip op. at 37

      “d) Analysis In our Institution Decision, although expressing some uncertainty with respect to certain of Patent Owner’s arguments on the preliminary record then before us, “we [were] not persuaded by Petitioner’s contentions that [(1)] Wang teaches [1d]’s code rate” (Dec. 53 (citing Pet. 62–65) or (2) “a POSITA would have been motivated to combine the teachings of Chou and Wang” (id. at 54 (citing Pet. 74)). Petitioner does not dispute those determinations in its Reply or otherwise. Furthermore, Petitioner does not address or otherwise dispute Patent Owner’s arguments challenging the asserted obviousness of claims 1, 4–6, 10–16, and 19–26 over the combined teachings of Chou and Wang. Thus, for at least the reasons set forth in our Institution Decision, we agree with Patent Owner that Petitioner fails to show that (1) one skilled in the art would have combined the teachings of Chou and Wang or (2) the combined teaching of Chou and Wang renders limitation 1(d) obvious. e) Conclusion Regarding Claim 1 For the foregoing reasons, we determine that Petitioner has not shown by a preponderance of the evidence that independent claim 1 is unpatentable over the combination of Chou and Wang.” slip op. at 47

      “we consider the level of ordinary skill in the pertinent art at critical time. Graham v. John Deere Co. of Kan. City, 383 U.S. 1, 17 (1966). The resolution of this question is important because it allows us to “maintain[] objectivity in the obviousness inquiry.” Ryko Mfg. Co. v. Nu–Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991). In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 3 U.S. Pat.

Generally, it is easier to establish obviousness under a higher level of ordinary skill in the art. Innovention Toys, LLC v. MGA Entm’t, Inc., 637 F.3d 1314, 1323 (Fed. Cir. 2011) (“A less sophisticated level of skill generally favors a determination of nonobviousness . . . while a higher level of skill favors the reverse.”). Petitioner asserts that a person of ordinary skill in the art “would have possessed a bachelor’s degree in electrical engineering or computer science, and two years of work experience in the field of network-based computer systems, such as systems for sending and receiving information over local networks and wide area networks (such as the Internet or World Wide Web).” Pet. 5 (citing Ex. 1002 ¶¶ 10–14).
