      “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

      “a) Combination of Mauer and Waylett In support of both Ground 1 and Ground 2, Petitioner argues that a person of ordinary skill in the art would have been motivated to combine Mauer’s and Waylett’s disclosures, “using Waylett’s Network-in-a-box 224 in each of Mauer’s WWAN 14 and WLAN 12, resulting in at least two DMA systems.” Pet. 11–13. 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. According to Petitioner, the combination would have included a number of beneficial features from Mauer. Id. at 14–15. Petitioner further advances three reasons that a person of ordinary skill would have had to combine the references’ teaching. Id. at 15–16. First, asserting that Waylett discloses cost benefits and Mauer discloses “an improved method and system for notifying mobile stations,” Petitioner contends the “references each provide reasoning” to combine their disclosures.

Second, Petitioner argues that a person of ordinary skill in the art would have been motivated to “improve Mauer’s distributed wireless network system by consolidating it into a single box, making it compact in design allowing for faster deployment.” Id. at 16. “Third, Waylett’s NIB would help mitigate the shared concern of Mauer—that is, reaching a mobile station as it roams or moves outside of the service or coverage area.” Id.” slip op. at 24

      “Petitioner does not establish that Mauer sends calls to voicemail based on the two determinations claim 1 recites. Resp. 55–56.

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).

For example, a person who merely installs solar panels for three years (satisfying “professional experience in solar energy”) while having some familiarity with module manufacturing would not be of ordinary skill in the design aspects of the ’060 patent as, for example, reflected by the claims at issue and the ’060 patent’s text and figures.

As a starting point, we note that “rotation” describes a specific type of movement—movement around an axis or central point. See, e.g., Ex. 2003, 2 (defining the verb “rotate” as “to turn about an axis or a center”). That is, the claims of the ’556 patent do not require there be no movement between the frame module and main body of the cushion module (or cushion module). Instead, the claims restrict a specific type of movement—rotation. The language of the claims tell us more. The movement that is to be prevented is the relative rotation between the frame module and main body of the cushion module (or cushion module)— movement of one component relative to another. As ResMed argues, none of the “non-rotatable” limitations expressly recites any spatial aspects of the relative rotation. See PO Resp. 21. The language of the “non-rotatable” limitation unambiguously state that relative rotation is prevented. See Ex. 1101, 10:19–21 (reciting “the frame module and the main body having shapes that prevent relative rotation”), 13:4–6 (reciting “the frame module and the main body have complementary shapes that provide for non-rotatable engagement relative to one another”), 14:14– 16 (reciting “the main body being shaped complementary to the frame module such that the main body and the frame module are not rotatable relative to one another”), 16:21–22 (reciting “the frame module and the cushion module are not rotatable relative to one another”), 18:19–23 (reciting “a combined elbow and frame module that is releasably snap-fitted to the cushion module, in a non-rotatable manner”), 19:23–25 (reciting “the main body having shapes that prevent relative rotation”). That is, the plain language of the claims requires preventing any relative rotation, not just some relative rotation about certain arbitrary axes. See, e.g., Ex. 2005 ¶ 37 (“[T]he claim language here indicating that rotation is prevented generally between the frame module and the cushion module/main body, a [person having ordinary skill in the art] would have understood this language to mean that rotation about all axes of rotation (about x-axis, y-axis, and z-axis) is being prevented.”). Significantly, Fisher fails to explain adequately how the plain and ordinary meaning of preventing relative rotation means preventing some relative rotation only. Although we agree with Fisher that an interpretation where the “non-rotatable” limitations restrict relative rotation about at least one axis is broader than an interpretation that restricts all relative rotation, such an interpretation is not necessarily the broadest reasonable interpretation when, as here, it does not comport with the plain and ordinary meaning of the limitation. See, e.g., In re Smith Int’l, Inc., 871 F.3d 1375, 1383 (Fed. Cir. 2017) (concluding that the broadest reasonable interpretation differs from the broadest possible interpretation).” slip op. at 16

      “The use of this type of connection provides a high degree of freedom of movement for the seal member so that the whole seal member does not simply mover linearly with respect to the faceplate when the adjustment mechanism is actuated. Instead, this configuration allows the upper is allowed to move on one direction, e.g., to be pushed away from the faceplate, while the lower portion at the opposite end of the seal member is moves in an opposite direction, e.g., is pushed toward the faceplate. In essence, the seal member is capable of being pivoted, articulated, or otherwise moved relative to the faceplate by this type of connection between the adjustment mechanism and the seal member. Id. ¶ 64 (emphasis added). For Matula’s seal member to pivot or articulate, socket 102 must move relative to ball 100 and the movement is a rotational movement. This function of a ball-and-socket joint is why Matula selected “this type of connection.” See id.; see also Ex. 2005 ¶¶ 54–56, 59 (describing the movement of Matula’s cushion module and adjustment mechanism 70). Specifically, when seal member 38 pivots or articulates, the point on seal member 38 where socket 102 connects to ring 104 will move in an arcuate path. Stem 76, on which ball 100 is connected, moves in a linear path. See Ex. 1102 ¶ 62. In order to transfer the linear movement of stem 76 and ball 100 to arcuate movement of ring 104, socket 102 rotates about ball 100. See id. ¶ 64. Indeed, Matula explains that, in an alternative embodiment, the adjustment mechanism can have a rigid connection (that is, not a ball-and-socket connection) with the seal member, which would result in the seal member moving linearly with respect to the faceplate.8 See Ex. 1102 ¶ 64. This description of the alternative embodiment further supports our finding that, with respect to the embodiment with ball 100 and socket 102, socket 102 rotates relative to ball 100. If this rotation did not take place, there would be no need for an alternative, rigid connection that would result in linear movement of the seal member. That is, if socket 102 did not rotate relative to ball 100, it would act identical to a rigid connection and result in linear movement of seal member 38, not articulating or pivoting (i.e., rotational) movement. Accordingly, because Matula’s ball 100 of its alleged frame module and socket 102 of its alleged main body of its cushion module interface or engage and because socket 102 rotates relative to ball 100 when knob 72 is actuated, we find that the embodiment of Matula that Petitioner relies on fails to satisfy the “non-rotatable” limitation of claim 1, as we have construed this term.9 For the reasons discussed above, we determine, based on the complete trial record, that Fisher has failed to demonstrate, by a preponderance of the evidence, that claim 1 is unpatentable under 35 U.S.C. § 103(a) over Matula. Further, in asserting that dependent claims 2–13, which depend, directly or indirectly from claim 1, are unpatentable, Fisher relies on its 8 We recognize that this alternative embodiment described in Matula would not include the relative rotation that we find in Matula’s ball-and-socket embodiment. The Petition, however, relies solely on Matula’s ball-and-socket embodiment and not an alternative embodiment. See Pet. 22, 30. 9 Because we find that Matula’s socket 102 rotates relative to ball 100 when knob 72 is actuated, we need not consider if any other movement asserted by ResMed takes Matula’s structure outside the scope of the “non-rotatable” limitation of claim 1. position that Matula discloses the “non-rotatable” limitation of claim 1. See Pet. 32–35 (addressing claims 2 and 4), 41 (addressing claims 3, 5, and 7), 94–97 (addressing claim 6), 98 (addressing claim 8), 105–109 (addressing claims 9–13). Accordingly, for the reasons discussed above in connection with our analysis of claim 1, we determine, based on the complete trial record, that Fisher has failed to demonstrate, by a preponderance of the evidence, that dependent claims 2–13 are unpatentable. 2.

      “persuaded Petitioner has provided sufficient articulated reasoning with rational underpinning explaining why one with ordinary skill in the art would have modified the teachings of the applied references to address the noted differences. See KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (“[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.”)). We consider Petitioner’s first reason to combine Oe and Etsuo “because they are in the same field of backlighting for liquid crystal display devices.” Pet. 36. The mere fact that both Oe and Etsuo are in the same field of endeavor falls short of an adequate rationale. The same field of endeavor analysis is merely the jumping-off point in reaching the determination of whether a claimed invention is obvious. See K-TEC, Inc. v. Vita-Mix Corp., 696 F.3d 1364, 1375 (Fed. Cir. 2012) (to qualify as prior art in an obviousness analysis, references must be analogous art—either from the same field of endeavor, or reasonably pertinent to the problem with which the inventor is involved). Next, we consider Petitioner’s second reason to combine because “both Oe and Etsuo relate to backlight devices that use light sources located at edges of a light guide.” Pet. 36 (citing Ex. 1004 ¶ 165). Although Petitioner relies on the testimony of Dr. Escuti, he does not proffer any persuasive facts, data, or analysis to support his opinion. See Ex. 1004 ¶ 165 (“Also, both Oe and Etsuo relate to backlight devices that use light sources located at edges of a light guide.”). Merely repeating an argument from the Petition in the declaration of a proposed expert does not give that argument probative value. Dr. Escuti’s opinion lacks sufficient support. For this reason, we do not credit the testimony of Dr. Escuti on this issue. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). Petitioner’s second reason is also unavailing because it does not address the entirety of Petitioner’s proposed modification. As discussed above, Petitioner relies on the disclosure in Etsuo for both the position of the plurality of light sources adjacent a single input edge claim element, as well as the output distribution having a greater width component than height component claim element. Petitioner’s reasoning, directed only to the use of light sources at the edge of the light guide, does not explain sufficiently why one of skill in the art would have replaced a single light source positioned adjacent one input edge of Oe, with the plurality of light sources disclosed by Etsuo that have an output distribution defined by a greater width component than height component.” slip op. at 20

      “We agree with Petitioner that “access attempt to said public telephone network” is not appropriately construed as a “period of time.” Nevertheless, disagreement between the parties over the scope of the fuller phrase, “during each access attempt to said public telephone network by said potential caller,” requires resolution—specifically, which of the steps that follow recitation of the “during” phrase must be performed “during each access attempt.” A grammatically rigid reading of the claim, which includes two colons and two instances of the word “and,” suggests an illogical construction in which the scope of “during each access attempt” includes the “prompting,” first “recording,” “matching,” “comparing,” “granting,” “monitoring,” and second “recording” limitations. The parties agree that such a construction is inappropriate, and we find it inconsistent with the Specification of the ’243 patent because at least the “monitoring” and second “recording” limitations logically require a connection established within the public telephone network before they can be performed. See PO Resp. 15– 16; Reply 19–20; Tr. 39:18–40:3 (Patent Owner acknowledging “sloppy draftsmanship”). Petitioner contends that, because “during each access attempt . . . ” is followed by a colon without further punctuation or indentation, “[t]he broadest reasonable interpretation of the claims would apply this limitation to only the first step following the colon: ‘prompting.’” Reply 19. Patent Owner contends instead that the “granting” limitation provides a logical conclusion to the “access attempt” so that each of the “prompting,” first “recording,” “matching,” “comparing,” and “granting” limitations are within the scope of “during each access attempt.” PO Resp. 15–16; see Tr. 38:7–20 (confirming Patent Owner’s position that the “granting” limitation is within scope). Patent Owner supports its position with testimony by Leonard J. Forys, Ph. D., who testifies as follows: Simply put, it is my opinion that an “access attempt” is defined by a starting point (e.g., the beginning of the attempt) and the point at which the “attempt” either succeeds or fails. In this case, because the claim recites an “access attempt to said public telephone network”, the “attempt” will succeed or fail (and thus conclude) when the caller is granted access to, or ultimately denied access from, the public telephone network. The period in between these two events comprises some calling procedure in which the caller may be asked to provide certain information, dial the outgoing number, authenticate himself/herself, etc. The above construction is thus supported by this common sense approach. Ex. 2004 ¶ 47. We credit this testimony, and afford it greater weight on this point than the testimony of Petitioner’s witness, Robert Akl, Ph.

See Ex. 2003, 46:24–48:22. We also agree with Patent Owner that a construction that affords greater scope to “during each access attempt” is consistent with the Specification of the ’243 patent.

The cursory assertion that the prior-art references are drawn from the same 4 With respect to the third statement, addressing claim 6, Dr. Akl provides the additional conclusory assertion that “One skilled in the art would understand that combining these references would be obvious and beneficial in that it would enhance the security of the system.” Ex. 1005 ¶ 94. broadly characterized field provides insufficient analysis concerning why and how a person of ordinary skill in the art would have modified or combined the prior art in the manner asserted, and inadequately articulates “reasoning with some rational underpinning to support the legal conclusion of obviousness.” See KSR, 550 U.S. at 418 (“[I]t can be important to identify a reason that would have prompted a person of ordinary skill in the relevant field to combine elements in the way the claimed new invention does.”). Furthermore, Petitioner’s perfunctory analysis is effectively rebutted by Dr. Forys, who testifies that “Susen and Gainsboro are directed to unrelated concepts” and “directed to very different architectures that are not easily combined.” Ex. 2004 ¶¶ 53, 56. We credit the testimony of Dr. Forys more strongly than that of Dr. Akl because Dr. Forys provides explicit reasoning to support his opinion that Susen and Gainsboro are concerned with different implementation settings, rely on different architecture structures, have technical incompatibilities, and are drawn from different fields. See id. ¶¶ 52–61; 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”).” slip op. at 16
