      “b) Walker Priority Date Under Dynamic Drinkware, the Petitioner is required to show that “the provisional application provides support for the claims of the patent or published application.” In re Riggs, 131 F.4th 1377, 1384 (Fed. Cir. 2025). Thus, Petitioner must show that (1) at least one claim of Walker is supported by its provisional (U.S. Provisional Application No. 60/378,289 (the “’289PROV”) and (2) the specific subject matter relied upon as prior art is supported by the ’289PROV. Id. Petitioner does provide a detailed explanation about how the ’289PROV supports claim 1 of Walker. See Reply 5–10. However, as Patent Owner argues, Petitioner fails to show that the ’298PROV provides support for the specific subject matter relied on in Walker. See Sur-Reply 3–9. Petitioner only explains how the ’298PROV discloses “predetermined criteria” but does not provide any other explanation for how the other subject matter relied on in Walker is supported by the ’298PROV. Thus, we find that Petitioner has failed to show that Walker is entitled a priority date before May 1, 2003. See Riggs, 131 F.3d at 1384 (noting while “a prior art patent or published application cannot be accorded the benefit of its provisional application’s filing date absent a showing that the provisional application provides support for the claims of the patent or published application,” the challenger must also show that “the specific portions of the patent specification identified and relied on” to demonstrate purported invalidity have written description support).” slip op. at 25

      “evidence that Kelly teaches limitations 1[d.i] and 1[d.ii]. As Patent Owner persuasively argues, “the recorded information regarding particular game play events” of limitations 1[d.i] and 1[d.ii] refers to “memory to . . . record game play information regarding particular game play events” in limitation 1[b.ii], but Petitioner does not map “the game play events” identified in limitation 1[b.ii] to limitations 1[d.i] and 1[d.ii]. In its Reply, Petitioner does not dispute Patent Owner’s assertion, but largely reiterates its arguments from the Petition. However, none of these arguments or evidence demonstrates that the “game play events” in limitations 1[d.i] and 1[d.ii] are same the “game play events” that are allegedly stored in limitation 1[b.ii]. Even if we accept Petitioner’s contention that it was not identifying button presses or the “game identifier,” but rather includes “game states and game events in the game process,” Petitioner provides no evidence or even arguments that what it has identified here relates to what it has identified for limitations 1[d.i] and 1[d.ii]. See Pet. 29–33 (citing Ex. 1005, 25:23–24, 26:59–27:1, 32:27–33, 37:1–10, 38:66–39:7 40:33–45, 56:49–51, 57:27–33). For these reasons, Petitioner has failed to show by a preponderance of the evidence that Kelly teaches or suggests limitations 1[d.i] and 1[d.ii]. Accordingly, we find that Petitioner has failed to show that claim 1 would have been obvious over Kelly. 2. Claims 3–9, 13, 17, 18, 23, 25, 26, 28, and 29 Claims 3–9, 13, 17, 18, 23, 25, 26, 28, and 29 all depend (either directly or indirectly) from claim 1. See PO Resp. 16 (explaining that the arguments for independent claim 1 also apply to the dependent claims inherent the deficiencies asserted with respect to the independent claims). We find Patent Owner’s arguments availing, as explained above. Accordingly, we find that Petitioner has failed to show by a preponderance of the evidence that claims 3–9, 13, 17, 18, 23, 25, 26, 28, and 29 would have been obvious over Kelly.” slip op. at 44

      “bears pointing out that the specification of the ’138 patent appears to explain what “a single allocation” means: If there are multiple QoS requirements within a single 3GPP PDP context, a single physical allocation of radio resources may be made to the UE. In this manner, a single PDP context implies a single CCTrCh. This single physical allocation of radio resources provided to a UE is shared amongst a number of services, in proportion to their respective QoS requirements, for example in proportion to the signalled weight values (Stier). Ex. 1001, 9:36–43 (emphasis added). Petitioner’s expert, Dr. Ding, explains that the “abbreviation CCTrCh was understood in the art to refer to a transport channel known as the Coded Composite Transport Channel.” Ex. 1003 ¶ 88. Dr. Ding testifies that Eckert teaches selecting data for uplink within a determined TTI and scheduling the uplink transmission on a transport channel, E-DCH, where scheduling of the E-DCH in a UE is controlled by a base station. Eckert, [0012] (“[A] new dedicated transport channel called Enhanced Dedicated Channel (E-DCH) has been introduced for this purpose. The fundamental characteristics of this new transport channel include . . . scheduling controlled by the base station, also called NodeB in UMTS…” Id. ¶ 90. In addition to Eckert disclosing a single transport channel E-DCH, Petitioner argues that Eckert discloses using a “finite quantum of physical resources” where “[t]he ’138 patent disclosure parallels Eckert, with both the E-DCH and CCTrCH transport channels relating to a UMTS uplink, employing spreading codes in code division multiple access (CDMA), and Reply 6 (citing Ex. 1005, ¶¶ 3, 8, 15, 23; Ex. 1071 ¶¶ 17–20; Ex. 1011 ¶¶ 6, 51).

      “Here, in our opinion, Patent Owner has shown that the Specification describes the potential destinations of a vehicle as limited to physically fixed, non-transient objects or features. PO Resp. 18–21. As an initial matter the ’805 patent is titled “Docking Assistant” and explains its purpose for guiding a “vehicle to a stop at a specific location.” Ex. 1001, codes (53), (57), Abstract. We acknowledge that claim 1 does not expressly recite that “at least one potential destination” is a fixed destination or location. See id. at 7:61– 63 (Claim 1 requiring “extracting from the acquired image data positional parameters of at least one potential destination relative to the motor vehicle;”). Yet, in the context of the relatively brief specification, there is no explanation, example, or embodiment which reasonably extends the meaning of “destination” or “potential destination” beyond a fixed location. The ’805 patent describes in the Abstract that [m]any day-to-day driving situations require that an operator of a motor vehicle guide the motor vehicle along a specific course and bring the vehicle to a stop at a specific location, for example in a parking bay or at a loading platform. Id. at code (57) Abstract. The Abstract explains in the next sentence that “[t]o assist a vehicle operator in such situations, a method and a suitable device for implementing this method, include detecting the potential target objects in the image data of an image sensor and identifying the potential target objects as potential destinations in a multi-stage exclusionary method.” Id. (emphasis added). Nowhere in this initial description of the invention, nor anywhere else that Petitioner points to, is there is expansion of the “specific location” or “potential destination” beyond a docking station or parking bay. Of course, the claim is not limited to these examples, as it would be inappropriate to read in such limitations from the Specification. See Acceleration Bay, LLC v. Activision Blizzard Inc., 908 F.3d 765, 771 (Fed. Cir. 2018) (“Acceleration again attempts to import structural limitations into claims lacking those limitations. . . .

      “Patent Owner’s declarant, Dr. Majumder, testifies to the contrary that “[r]ead as an engineer, the ‘805 patent’s present invention is framed around guiding a vehicle to fixed, physical destinations (exemplified by docking stations and similar structures) without fiducials or special markings.” Ex. 2010 ¶ 81. Considering Broggi, Dr. Majumder testifies further that “[a] moving object, such as a preceding car, is not a valid destination under the ‘805 Patent, because it is not a stationary location at which the host vehicle can be guided to stop. To treat such a vehicle as a ‘potential destination’ would lead to collision, not guidance.” Id. ¶ 86. As discussed in our claim construction, given a plain reading of claim 1 in light of the Specification, our understanding of the ’805 patent is consistent with Dr. Majumder’s testimony. We agree that Broggi is directed expressly to the platooning of moving vehicles, and not physically fixed destinations as the proper claim construction requires. Because Broggi does not disclose the use of physically fixed “potential destinations” as required, e.g., in limitations [1.2]–[1.3], and neither Huttenlocher nor Brady are relied upon to overcome this deficiency, Petitioner has not met its burden of persuasion to show by a preponderance of the evidence that claim 1 would have been obvious over Broggi in view of Huttenlocher and Brady.” slip op. at 27

      “offers nothing to suggest that its card information ‘tells you’ where to store the fingerprint data.” ASSA ABLOY AB, 2025 WL 3134960 at *3. Reversing our determinations as to Hsu, the Court found that the testimony of Petitioner’s declarant, Mr. Lipoff, “merely confirms the associative link between the card information and the biometric data. Still missing is any non-conclusory testimony that Hsu’s card information determines the memory location of the biometric data.” Id. at 8. Therefore, on remand, a central question is whether Petitioner has shown sufficiently that Tsukamura cures this deficiency. Petitioner has not done so. In the Petition, Petitioner relies on Tsukamura for teaching a specific location for storing fingerprint data. See Pet. 75 (stating that “Tsukamura’s index number specifies the physical memory location in the memory”). Petitioner argues that “[t]hus, Tsukamura discloses defining, dependent upon the “index number N index,” a memory location for storing a biometric signature (e.g., a fingerprint template), i.e., ‘a memory location is specified by the card information.’” Id. at 75–76 (citing Ex. 1006 ¶ 215). In support, Petitioner’s declarant, Mr. Lipoff, testifies that “[i]f the Tsukamura implementation were used for Sanford-Hsu database, each user/account number would specify a different entry (index number) in the database.” Ex. 1006 ¶ 394. Tsukamura’s index number N index does not teach or suggest much more than Hsu’s using “an account number or employee number, to access a stored there during an enrollment procedure.” Compare Ex. 1004, code (57), with Ex. 1005, 4:7–11. That is, both references arguably teach defining, i.e., setting or establishing, a certain location in a database for biometric data. For example, as described above, Tsukamura’s fingerprint template Temp is stored in flash ROM 35 at a defined index number N index in the database. Id. 4:7–11, 50–54. However, neither Petitioner, nor Mr. Lipoff, persuasively explain how or why Tsukamura’s fingerprint template Temp, stored at index number N index, is commensurate with “means for defining, dependent upon the received card information, a memory location in a local memory external to the card” as recited in claim limitation 13[C].

      “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.

      “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).

      “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
