    “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.

    “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

    “Further, we find the testimony of Patent Owner’s declarant more persuasive based at least on his consideration of Swenson as a whole and his more detailed analysis and explanations. For example, Patent Owner’s declarant explains in detail why, “[i]n the context of a HTTP GET request and response, as disclosed in Swenson, the message does not constitute a single packet but a flow of packets:” Furthermore, Swenson discloses that the steering device 130 “sends an ICAP request message 516 comprising [a] HTTP GET request header and a portion of the [HTTP] response payload to the network controller 140, which inspects the message to determine whether to monitor the flow or optimize the video.” Ex. 1007 [0065]. In the context of a HTTP GET request and response, as disclosed in Swenson, the message does not constitute a single packet but a flow of packets. The reference to a HTTP request and response “header” and “payload” are thus not references to the header and payload of a packet. A POSA would know that despite common parlance references to “HTTP packets,” HTTP does not pertain to individual packets, whereas packet transmission is governed by the TCP protocol. HTTP utilizes TCP to exchange data such that information may be used by an end user (e.g., a video or audio stream). Even assuming that Swenson’s controller were analyzing the header and payload of an HTTP request/response, a POSA would understand that this analysis is not at the packet but at the flow level and thus does not constitute deep packet inspection. Ex. 2025 ¶ 69. Petitioner’s declarant merely responds by reiterating what was previously stated: Swenson is explicit in stating that its inspection techniques include inspection of “a portion of the [HTTP] response payload.” . . . A POSA would have understood the analysis of the “response payload” to be DPI by a DPI-capable controller, as DPI refers to monitoring the payload of a packet.” slip op. at 15

Asserting that “Mauer teaches providing sufficient network coverage by use of different kinds of networks, network interfaces, and protocols,” Petitioner contends that a person of ordinary skill in the art would have recognized that “Waylett discloses an inexpensive way to implement the same networks used in Mauer’s WWAN 14 and WLAN 12.” Id. Citing similarities in Mauer’s and Waylett’s systems, Petitioner argues that “a POSITA would have been able to modify Mauer’s WWAN 14 and WLAN 12 networks so that each network uses Waylett’s NIB 224.” Id. at 14.

The Petition, at best, attempts to establish that Mauer directs to voicemail when a “communication session cannot be established over the first or second wireless network.” Pet. 37. But a general determination that a “communication session cannot be established” does not teach or suggest claim 1’s specific requirements that first, the DPR is utilized in the specific circumstance that the second mobile subscriber is not located within the first wireless coverage area (with this determination being made based on HLR and VLR information), and second, that the DPR is also not located within the second wireless coverage area (with this determination being made based on CLR information).

    “By contrast, in his Rebuttal Declaration, Dr. Mihran disputes Dr. Panescu’s new description of the operation of Schulman, noting that the current through R9 is not increased as a result of the current regulator R8/Q7 turning on, but that “[i]nstead, it is the increase in current through R9 in excess of the desired 40 mA operating current that causes the current regulator R8/Q7 to turn on, which acts to shunt this excess current through Q7, thereby diverting it away from the battery to maintain the desired operating condition during charging.” Ex. 2010 ¶ 6 n.3 (citing Ex. 1005, 5:2–7, 5:15–38, 9:57–68). We credit the testimony of Dr. Mihran, as supported by the cited portions of Schulman, over the unsupported testimony of Dr. Panescu in regard to how Schulman operates to measure current at R9.

Patent Owner further argues, and we further agree, that the voltage across output leads 51 and 52 of Schulman is not an input to the external power source separate from the measured current through R9 in Schulman. See APO Sur-reply 11–16 (citing, e.g., Ex. 1003 ¶ 75; Ex. 2002 ¶ 46; Ex. 1005, 6:35–38; Ex. 2010 ¶¶ 4–7). In support of Patent Owner, Dr. Mihran states that “[t]he voltage between nodes 51 and 52 is never provided to the external power source in Schulman.” Ex. 2010 ¶ 4. According to Dr. Mihran, “Schulman discloses that the sole input provided to the external power source that the external power source uses to automatically regulate its power output is the input that derives from the amount of current flowing through the current sampling resistor R9.” Id. ¶ 5 (emphasis omitted) (citing Ex. 1005, 4:45–53, 6:35–38; Ex. 2002 ¶ 46). Dr. Mihran further states as follows: My understanding of Dr. Panescu’s opinion is that he does not contend that the voltage between nodes 51 and 52 is ever sent to the external power source as an input, and instead simply asserts that if “the voltage across leads 51 and 52 exceeds a predetermined amount,” then the current through R9 increases, which in turn “causes the power supplied by the external power source to decrease.” (Ex. 1012 at ¶16.) This does not represent a separate input, however, because the input derived from the current flowing through the current sampling resistor R9 (i.e. the load modulation frequency of telemetry circuit 12, the components of which “form a free-running multivibrator”) is what Dr. Panescu also identifies as satisfying the first input, “a value associated with said current passing through said internal battery.” (Ex. 1012 at ¶14 (“when the current through the internal battery . . . increases above a predetermined target value, the current regulator turns on, increasing the current through current sampling resistor R9.”) operating conditions may influence the value” of the amount of current flowing through current sampling resistor R9, and the current through R9 is the “only value that is communicated to the external power source,” corresponding to a single input that “cannot satisfy both of the two inputs required by claims 3, 6, 9, 12, 15, and 18 of the ’148 patent.” Id. ¶ 6. Dr. Mihran further states as follows: I understand Dr. Panescu’s opinion to be that, because Schulman discloses that the current through R9 is used by the external charger to automatically vary its output, any “value” that influences the amount of current through resistor R9 is a “separate respective input[] used by the external power source as a basis for automatically varying its power output.” ([Ex. 1012 ¶14].) In other words, Dr. Panescu simply identifies a voltage across two points in the circuit that he claims affects the current through R9 and contends that that voltage satisfies one of the two required separate inputs based on its alleged indirect impact on the output of the external charger. This strained interpretation of the claims renders superfluous the two separate inputs to the external power source required by claims 3, 6, 9, 12, 15, and 18 of the ’148 patent: (1) “a value associated with said current passing through said internal battery” and (2) “a signal proportional to said current passing through said internal battery” (claims 3, 9, and 15) and “measured voltage associated with said current passing through said internal battery” (claims 6, 12, and 18). In any circuit, there may be multiple components (e.g., transistors, switches, diodes, etc.) that can influence the current through a particular resistor. For example, in Schulman the current drawn by the stimulation portion of the implant circuit will influence the amount of current through R9. Dr. Panescu’s interpretation that a voltage or current at these components represents a “separate input” in Schulman is incorrect, because the sole input that is telemetered back to the external charger is the input derived from the amount of current flowing through R9.” slip op. at 35
