“of Choi to support its argument that an ordinarily skilled artisan would have understood Choi’s infrared lamp housing to define a concave shape as claimed. See Pet. 61–62. With only this explanation and evidence from Petitioner and Dr. Jenson, however, we cannot not discern how these portions of Choi would have so apprised an ordinarily skilled artisan. For example, the side view of the infrared lamp housing, illustrated in Figure 5 reproduced below, shows the housing having a convex, rather than concave, shape. See Ex. 1008, Fig. 5. Furthermore, paragraphs 20 and 48 refer to the housing’s “circular” shape and outer periphery and also “tubular” shape. See id. ¶¶ 20, 48. But these descriptions, either alone or together with Figure 5, also do not support adequately a finding that Choi’s housing is concave. Choi’s teachings in paragraphs 20 and 46 regarding the lamp housing guiding or directing infrared light from the lamp to irradiate the skin of a user, without more, are similarly deficient. See id. ¶¶ 20, 46. And although Dr. Jensen appears to equate “concave” with “inner circular,” he does not provide the basis for his testimony or explain what “inner circular” means, particularly in the context of distinguishing a convex shape from a concave shape. See Ex. 1002 ¶ 197.

See Pet 24–26. For example, Dr. Young testifies that a person of ordinary skill in the art would have recognized that Kumar discloses the details, at a granular level, of Fujiyoshi’s capacitive sensing systems and would have looked to Kumar for understanding of how to implement Fujiyoshi’s system. Ex. 1002 ¶ 145. Patent Owner does not point to persuasive evidence to rebut this opinion. Moreover, Petitioner cites to Kumar, not only for an explicit disclosure of capacitive pickoff signals, but also for its disclosure of both DC bias and AC carrier signals and recognizing the applicability of an AC carrier pickoffs that operates without DC bias.

“Patent Owner challenges Petitioner’s reliance on Broggi as relating to platooning rather than guidance to a fixed endpoint. Prelim. Resp. 21–38. All of Patent Owner’s arguments in that regard depend on us adopting Patent Owner proposed construction for “potential destination.” Id. As discussed above, we do not agree that the claimed potential destinations should be limited to fixed locations. See supra at 7–8 (§ II.B.1). Accordingly, we do not agree with Patent Owner’s arguments regarding platooning rather than guidance to a fixed endpoint. Although Patent Owner asserts that Broggi also does not calculate an “optimized path” as claimed (Prelim. Resp. 29–33), that argument similarly depends on a construction for “potential destination” that is limited to fixed locations. See id. at 31 (arguing that the “car taught in Broggi cannot calculate an ‘optimized path’” because it “has absolutely no knowledge of the destination for the platoon”), 32 (“[I]n Broggi, the ARGO does not calculate a path to a destination because it doesn’t have any knowledge regarding the destination of the preceding car.”). We do not agree with Patent Owner’s argument because, as discussed, the challenged claims do not require an optimized path to a fixed location, but instead read on an optimized path to a transitory location, such as the location of Broggi’s preceding vehicle at a given time. We agree with Petitioner that Broggi teaches an optimized path because it generates steering commands that lead toward the preceding vehicle and because those commands consider the steered vehicle’s capabilities. See Pet. 34–35. Additionally, Patent Owner challenges Petitioner’s reliance on Huttenlocher as failing to disclose the claimed “mathematical tree structure.” Prelim. Resp. 38–62. All of Patent Owner’s arguments in that regard depend on us adopting Patent Owner’s proposed construction for “mathematical tree structure.” Id.

At this stage of the proceeding, however, we decline to read into the accepted District Court construction of “integration time” the additional negative limitation that Patent Owner proposes––i.e., the term “scene” excludes a photograph or still image. This is an issue that warrants a more fully developed record by both parties. For now, even without having the benefit of Petitioner’s position on this issue, we determine that there is a reasonable likelihood that Petitioner would be successful in refuting Patent Owner’s proposed negative limitation. This is because the ’158 patent makes clear that the invention is intended to address “a need for a digital camera in which the effective single-frame dynamic exposure range is expanded” to accommodate situations wherein a scene may include “an indoor room with a window view of the outdoors, an outdoor scene with mixed shadows and bright sunshine, and evening or night scenes combining artificial lighting and shadows.” Ex. 1001, 1:43–49, 2:28–42, 3:39–41. The ’158 patent explains that “[i]mage capture by the camera is performed using multiple camera channels, and each camera channel is controlled during a frame under an independent integration time.” Id. at 3:47–50 (emphasis added). The ’158 patent states further that its “digital camera systems, through the use of multiple integration times, enable formation of an image having a wide dynamic range by combining the data from all camera channels to form a composite single frame.” Id. at 3:28–61 (emphasis added). Still further, the ’158 patent states for one exemplary embodiment that “[t]he integration time of at least one channel is controlled relative to the integration time of at least one other channel so that an image formed by combining data of a frame received simultaneously from the channels has a relatively large dynamic range.” Id. at 5:6–11 (emphasis added). Rather than supporting Patent Owner’s contention that the meaning of the term “integration time” excludes a photograph or still image, the above illustrative teachings from the ’158 patent establish at least a reasonable likelihood that Petitioner would succeed in establishing that “integration time,” and the term “scene” more particularly, encompasses the time the image sensor collects and integrates signals for a photograph or still image. As Patent Owner appears to acknowledge, the ordinary meaning of “scene” encompasses a “shot,” as well as, a “frame” (Prelim. Resp. 27 (citing Ex. 2011, 267–269)) and, as such, it would be counterintuitive to adopt an interpretation of “integration time” that excludes the very parts that make up a scene.

Petitioner’s evidence shows that Matsushima discloses “two independent imaging systems” controlled by CPU 30 that each form an image on the light-receiving surfaces of CCD sensors 18A and 18B via their respective imaging optics 14A and 14B. Ex. 1007 ¶¶ 17, 28 (emphasis added). In that configuration, Matsushima teaches that CCD sensors 18A and 18B each has an associated CCD drive circuit 20A and 20B that apply CCD drive pulses to retrieve the accumulated signal charges of their respective CCD sensors. Id. ¶ 23. Additionally, Matsushima teaches that CCD sensors 18A and 18B each has an “electronic shutter function that controls the accumulation time (shutter speed) of the charge accumulated by each sensor via shutter gate pulses” and that the shutter speed is determined based on integration of the Red, Green, and Blue signals in a single frame by the integration circuit 60A and 60B. Id. ¶¶ 24, 31, 34–35. Patent Owner notably does not dispute Petitioner’s cited evidence shows Matsushima discloses a processing component configured to control the integration time for CCD sensors 18A and 18B. See Prelim. Resp. 34– 50. Instead, despite Matsushima’s teaching that its imaging systems are independent, Patent Owner argues that Matsushima does not disclose independently controlling the integration time for CCD sensors 18A and 18B. Id. This is so, according to Patent Owner, because Matsushima describes operating CCD drive circuits 20A and 20B synchronously and describes using a single, common shutter speed for each of CCD sensors 18A and 18B. Id. at 35–38 (citing Ex. 1007 ¶¶ 17, 23, 27, 31, 34–35; Ex. 2005 ¶¶ 88–92). At this stage of the proceeding, Patent Owner’s argument raises genuine issues of disputed fact that would be best resolved on a fully developed record, rather than undermining the reasonable likelihood of success of Petitioner’s contention. In particular, going forward, the record would benefit from the parties addressing the issue raised by Patent Owner regarding whether Matsushima discloses to a skilled artisan individually controlling the shutter speed of each CCD sensor 18A and 18B. For example, although Patent Owner notes that Matsushima suggests an embodiment that may use a single, common shutter speed value and an intention for each circuit to be driven synchronously, it is unclear why those facts demonstrate Matsushima fails to suggest individually controlling the integration time of the disclosed independent imaging systems. To the extent Patent Owner is suggesting that limitation 1.3 does not encompass individually controlling the integration time of CCDs sensor 18A and 18B to operate synchronously with a single, common shutter speed value, Patent Owner should explain how the intrinsic record of the ’158 patent and the understanding of a skilled artisan at the time of the invention supports that position. Nevertheless, at this time and on this record, we determine there is a reasonable likelihood of success that Matsushima renders unpatentable claims 1, 2, 5, 8, 9, 11, 13–16, and 19.” slip op. at 21

“As discussed in section II.C.2 above, we interpret a “blade member” to have a cutting surface. Petitioner does not support adequately its assertion that Lint’s barbs 19 have a cutting surface. Petitioner acknowledges that Lint discloses “barb 19,” but Petitioner merely labels the barbs as blade members in annotated versions of Lint Figure 2. Pet. 21–22, 24. Petitioner’s witness, Dr. Kuhn, provides substantially identical testimony, also failing to explain how Lint’s barbs have a cutting surface or perform a cutting function. See Ex. 1019 ¶¶ 68, 70. Such conclusory assertions fail to satisfy Petitioner’s burden of persuasion. To the contrary of Petitioner’s assertions, Lint discloses that its barbs do not perform a cutting function. Lint discloses that its barbs retract to the closed position upon impact with an animal. Ex. 1002, 2:62–67. Only when the arrowhead has “completely penetrated the flesh of an animal” does the spring urge the barbs into the extended position “to retain the arrowhead within the animal.” Id. at 2:67–70.6 Lint discloses that its barbs provide 6 During the hearing, Petitioner’s counsel argued that Lint’s disclosure of its barbs deploying “[a]fter the arrowhead 10 has completely penetrated the flesh of an animal” means the spring urges the barbs forward after the resistance to the removal of the arrow from an animal (id. at 1:53–57, 2:67–70), but Lint does not disclose its barbs as performing any cutting function.

“A claimed modification to the prior art may be an obvious design choice if the claimed structure performs the same function as in the prior art and it presents no novel or unexpected result over the prior art. See In re Kuhle, 526 F.2d 553, 555 (CCPA 1975) (finding that the use of the claimed feature “would be an obvious matter of design choice” when it “solves no stated problem” and “presents no novel or unexpected result” over the disclosed alternatives); Ex parte Maeda, Appeal No. 2010-009814, at 6–7 (PTAB Oct. 23, 2012) (informative) (“‘design choice’ may be appropriate where the applicant fails to set forth any reasons why the differences between the claimed invention and the prior art would result in a different function or give unexpected results” (citing In re Chu, 66 F.3d 292, 298–99 (Fed. Cir. 1995)). The ’177 patent explains that the purpose of the recited blade members is to maximize the cutting surface of the arrowhead through an animal’s soft flesh to increase the likelihood of a successful kill and minimize undue suffering of the animal. Ex. 1001, 1:26–30, 4:8–10, 4:21–24. The purpose of Lint’s barbs, on the other hand, is to resist removal of the arrow from an animal. Ex. 1002, 2:67–70. Indeed, Lint discloses that only when the arrowhead has “completely penetrated the flesh of an animal” does the spring urge the barbs into the extended position. Id. Thus, contrary to the conclusory assertions of Petitioner and Petitioner’s witness, Dr. Kuhn (see Pet. 49–51; Ex. 1019 ¶ 119), the recited blade members and Lint’s barbs perform vastly different functions. Neither Petitioner nor Dr. Kuhn explains adequately how the proposed modification to Lint’s barbs would be a mere matter of design choice.
