    “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.

In particular, Thomason is interested in rotating and cropping images to reduce the effect of poor orientation. Pet. 9 (citing Ex. 1004 ¶¶ 2, 34, 36).

The preponderance of the evidence also supports that a person having ordinary skill in the art would have had reason to combine the Pacurariu’s teachings with Thomason to predictably improve Thomason. Thomason teaches correct rotation of video data and makes use of rotation sensor to correct rotated images. Pet. 19–21 (citing, e.g., Ex. 1004 ¶¶ 4, 27, 29, 35; Ex. 1002 ¶¶ 76–77).

Pacurariu further teaches that its tilt data angle can be stored for each “video frame.” Id. at 22 (citing Ex. 1005 ¶ 52).

Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator. Ex. 1005, 2:66–3:1. Dobashi, therefore, teaches that RSm is an indicator of surface waviness, which Dobashi explains is different than surface roughness. Id. at 2:66– 3:3, 6:23–29. Given these teachings in Dobashi, neither Petitioner nor Dr. Josefowicz sufficiently explains how or why a POSITA would have been motivated to implement Dobashi’s RSm values to make Hanafusa’s surface roughness low-profile.

    “II. STANDARD OF REVIEW When rehearing a decision on institution, we do not review the merits of the decision de novo, but instead review the decision for an abuse of discretion. 37 C.F.R. § 42.71(c). An abuse of discretion may be determined “if a decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if the decision represents an unreasonable judgment in weighing relevant factors.” Arnold Partnership v. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004) (citing In re 1 US 2013/0108922 A1, published May 2, 2013 (Ex. 1004, “Shinozaki”). 2 G. Khatibi, Temperature Dependent Elastic and Thermal Properties of Thin Copper Foils, Copper; Proceedings of the International Conference Copper ’06 (2006) (Ex. 1006, “Khatibi”). 3 Korean Patent Pub.

    “For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE[6] value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added).” slip op. at 4

    “Petitioner, however, does not adequately explain why a POSITA would have been motivated to modify Kim’s copper foil surface to have a Pc value of 19.2 as reported in Griesi. In particular, neither Petitioner nor Dr. Randall points us to, nor do we discern, any teaching in Griesi that a peak count of 19.2 provides any particular benefits or properties that would have lead a POSITA to modify Kim’s copper foil surface as Petitioner proposes. Instead, Petitioner’s arguments that a POSITA would have been motivated to modify Kim’s copper foil surface with Griesi’s peak count patent itself. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 421 (2007) (stating that the fact finder must be aware “of the distortion caused by hindsight bias and must be cautious of arguments reliant upon ex post reasoning”). It was Petitioner’s burden to establish that the combined teachings Kim and Griesi disclose limitation [1g] as proposed. We are not persuaded that we misapprehended Petitioner’s argument when we determined that Petitioner did not meet that burden.” slip op. at 8

Although we do not discern any meaningful distinction between the parties’ formulations, we adopt Patent Owner’s description of a person of ordinary skill as it is consistent with the prior art and challenged patent’s specification.

    “a first current through one or more output ports of the at least one output port in a first operating mode,” and “is configured to output a second current capable of starting a vehicle engine through the pair of output terminals in a second operating mode.” Ex. 1001, 8:25–34. Claim 21 has similar first and second operating-mode limitations. Id. at 9:40–46. Patent Owner proposes that “[t]he proper construction for ‘first operating mode’ is ‘an operating mode of the portable backup charger wherein the battery pack is configured to output a first current through one or more output ports of the at least one output port, and outputting a second current capable of starting a vehicle engine through the pair of output terminals is inhibited.’” PO Resp. 25. Similarly, Patent Owner argues “[t]he proper construction for ‘second operating mode’ is ‘an operating mode of the portable backup charger wherein the battery pack is configured to output a second current capable of starting a vehicle engine through the pair of output terminals, and outputting a first current through one or more output ports of the at least one output port is inhibited.’” Id. at 27. Patent Owner asserts that claim differentiation supports its construction because dependent claim 3 recites “a third operating mode for outputting the first current and the second current simultaneously,” and “if the battery pack could output the first current and the second current simultaneously in the first operating mode, then there would be no difference between the claimed first operating mode and the claimed third operating mode.” Id. at 26. We disagree with Patent Owner’s constructions because, as Petitioner explains, they wrongly import current-inhibiting limitations beyond the plain language in the claim. Pet. Reply 1. Nothing in the at-issue language addresses inhibiting current. In addition, the claimed first and third operating modes are still distinct without importing additional limitations because outputting just the first current is sufficient for the first operating mode, but not for the third. In other words, whereas the third operating mode requires simultaneity, the first and second merely permit it. Thus, claim differentiation does not support Patent Owner’s construction. Last, although Patent Owner asserts that its construction “is consistent with the specification,” nothing in the cited passages describes inhibiting current. Prelim. Resp. 26 (citing Ex. 1001, 4:30–33, 5:30–33, 5:58–62). Instead, the specification characterizes the modes solely by what the portable charger “can output,” not what is inhibited. Ex. 1001, 4:30–33, 5:30–33, 5:58–62. Thus, we decline to read the first and second operating modes to require the current-inhibiting features that Patent Owner asserts.” slip op. at 6

    “Patent Owner argues the two current paths are not different because Chen’s Figure 1 shows they overlap between the lithium battery and the output control circuit and “only diverge when making the connection to the output control circuit.” PO Resp. 32. We disagree. First, Patent Owner’s argument is based on a claim construction for “different” current paths that we do not adopt for the reasons above. In addition, we agree with Petitioner that Chen shows the claimed different current paths even under Patent Owner’s construction. Pet. Reply 8–12. Specifically, as Petitioner explains, a skilled artisan would recognize that Chen’s physical circuits are depicted in Figures 4–7, rather than in Chen’s Figure 1, which is merely a “block diagram of the principle of present invention.” Id. at 9; Ex. 1006 ¶ 15. Unlike Figure 1, Chen’s Figures 5, 6, and 7 show current paths between the battery and USB outputs, and between the battery and DC multi-gear output, that do not overlap with the high current path shown in Chen’s Figure 4. Pet. 9–12. Based on Petitioner’s analysis and for the reasons above, we agree with Petitioner that Chen teaches the claimed “pair of output terminals coupled to the battery pack and having a current path to the battery pack different from that of the at least one output port to the battery pack.”” slip op. at 10

    “Patent Owner asserts one skilled in the art would not have added White’s fuse to Chen because doing so was “unnecessary” given Chen’s built-in relay K1 that already provides protection. PO Resp. 42–43. We disagree because, as Petitioner notes, “the Petition cited ample evidence that both layers of over current prevention provide improved safety and protection to the battery.” Pet. Reply 17 (citing Pet. 31–33); see also, e.g., Pet. 31 (describing “advantageously reduc[ing] the likelihood of damage”), id. at 32 (describing “the additional benefit of a safety fuse along a jumper cable to promptly cut off current in the event of a short circuit” and “more simplified maintenance and repair”). Given Petitioner’s unrebutted rationale, Petitioner has articulated sufficient reasoning with rational underpinning to support the legal conclusion that adding White’s fuse and polarity-protection connector to Chen’s power-supply system would have been obvious to one of ordinary skill in the art. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). Other than the arguments addressed above, Patent Owner does not additionally challenge Petitioner’s obviousness showing based on Chen and White. We have reviewed Petitioner’s arguments and evidence and, based on that analysis, we find Petitioner has shown by a preponderance of the evidence that claims 1, 2, 6–9, 11–14, 16–22, 25–28, and 30–33 would have been obvious over Chen and White.” slip op. at 15
