“At this stage of the proceeding, we disagree with Patent Owner’s construction that requires “distinguishing among different types of targets” in order to obtain “target specific feature information” because claim 1 does not recite such a limitation. Instead, we agree with Petitioner that the plain and ordinary meaning “requires target specific feature information for distinguishing specific targets from background clutter, not other targets.” Reply 2. We note that claim 1 does not require distinguishing between different targets nor does it include any recitation directed to a particular “learning process (e.g., Generalized Hebbian Analysis),” as Patent Owner implies. Sur-reply 2. We also agree with Petitioner that the doctrine of claim differentiation supports Petitioner’s construction because claim 7 adds a limitation not present in claim 1 by reciting “distinguish[ing] two target classes or a plurality of target classes from one another.” Ex. 1001, 12:28–30. Moreover, the Specification contemplates selecting target specific feature information to distinguish specific targets from background clutter without distinguishing among different types of targets because the Specification explains that the inventor tested the preferred classification system using target objects “of several different types” such that “the preferred embodiment needed to find receptive fields common to all types.” Id. at 9:41–48 (emphasis added). Accordingly, we find Petitioner’s proposed construction of “target specific feature information to distinguish specific targets from background clutter” as having its plain and ordinary meaning to be reasonable and consistent with the intrinsic record. Thus, we adopt it for purposes of this Decision. On this limited record, and at this early stage of the proceeding, the Board has not made a final determination on the construction of “target specific feature information to distinguish specific targets from background clutter.” We encourage the parties to further develop this argument (such as to the extent it would differentiate the prior art) and their positions at trial.” slip op. at 15

“On this record, we find Petitioner has shown sufficiently that Barnard teaches using “target specific feature information” to distinguish specific targets from background clutter, as required by claim 1. See Pet. 16–32. As set forth above, on the current record we do not construe the claim limitation reciting “target specific feature information to distinguish specific targets from background clutter” to require “distinguishing among different types of targets based on tailored feature selection,” as Patent Owner suggests. Prelim. Resp. 27. Instead, we agree with Petitioner that the plain and ordinary meaning of the claim limitation simply “requires target specific feature information for distinguishing specific targets from background clutter, not other targets.” Reply 2; Section II.C.1. Based on the current record, and consistent with this understanding, we find Petitioner has shown sufficiently that Barnard uses various calculated data statistics to select a set of features and an associated target detection threshold in order to distinguish specific targets from background clutter. See Pet. 16–17 (citing Ex.1003 ¶¶ 65–68 (citing to Ex. 1005, 2:30–36, 5:36–49, 6:62–68)). Petitioner explains that Barnard “discard[s] or exclude[es] features that have a statistical distribution width exceeding a predetermined amount,” and as such, “Barnard selects features (i.e., the remaining features not excluded) that are used to distinguish specific targets from background clutter.” Id. at 17 (citing Ex.1005, 2:28–39; Ex. 1003 ¶ 66). Patent Owner argues that “[a]t best, Barnard generically applies the same set of features to all potential targets, and then filters out those deemed unreliable due to statistical variance,” and relying on the Declaration testimony of Dr. Majumder, contends that “[t]his is not the same as selecting features based on their discriminative power for specific target classes, as required by the claims.” Prelim. Resp. 21 (citing Ex. 2007 ¶ 71); see also id. at 25 (“The reference makes no distinction between different types of targets and does not describe using different feature sets or decision boundaries tailored to particular target classes.”), 30 (“Petitioner’s attempt to equate Barnard’s one size-fits-all filtering with the claim’s target-specific discrimination reflects a misunderstanding of both the reference and the invention.”). However, on the current record, Patent Owner’s argument is unpersuasive at least because it is based on an overly restrictive construction of the limitation “target specific feature information to distinguish specific targets from background clutter.” As discussed above, claim 1 does not require distinguishing between different targets or between specific target classes.

Therefore, at this stage of the proceeding, we need not reach Patent Owner’s assertions as to the third alternative argument and evidence Petitioner provides, namely the combination of examples 2), 3), and 4). For completeness, however, we acknowledge that Bucknell does not expressly combine examples 2), 3), and 4), mainly because example 4) only refers back to example 2). However, we note that from a plain reading of Bucknell’s written description it may not be a significant leap to understand that the disclosed combination of examples 2) and 4), with first and second portions 90 and 95 populated in reverse order as taught in example 4), that this combination could be subsequently modified by example 3) to provide a “second iteration . . . based on buffered data.” Ex. 1006 ¶¶ 26–27. In other words, on the current record it is not clear why “the unused resource” of Bucknell’s second portion 95 cannot also “be made available,” to the first portion 90 if the order was simply reversed per the combination of examples 2) and 4). 3. Conclusion as to Claim 1 In summary, we find Petitioner’s arguments and evidence sufficient to show a reasonable likelihood that claim 1 is unpatentable over Eckert in view of Bucknell and Lohr-1. On the current record, we find that Bucknell discloses “a first iteration” based on receiving the priority values for logical channels associated with the MAC-d flows. Ex. 1006 ¶ 26.

As to the issue of whether the Petition provides sufficient explanation or motivation to combine Bucknell’s examples 2), 3), and 4), which is an alternative argument to Petitioner’s other mappings for limitation [1.9] which we find sufficient for institution, we leave this alternative mapping issue for development at trial.

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.

“Record evidence supports Petitioner’s contentions that a skilled artisan would have had reason to look to Kumar for further implementation details of a circuit that performs functions like those performed by Fujiyoshi. 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. Pet. 24–26 (citing Ex. 1005 3:65–4:2, 6:29–36). We credit Dr. Young’s testimony on this issue and agree with Petitioner that a person of ordinary skill in the art, looking at Fujiyoshi’s description of capacitive sensing systems, would be motivated to look to Kumar for its more detailed teachings of the implementation details of such systems and would combine these details to arrive at limitation 1(a). We determine that Petitioner has shown, by a preponderance of the evidence, that one of ordinary skill in the art would have been motivated to combine Fujiyoshi and Kumar in the manner argued by Petitioner.” slip op. at 37

“We find the District Court’s reasoning persuasive, and we, like the District Court, decline to adopt Petitioner’s overly broad proposed construction. However, for purposes of deciding the dispositive fact issue before us, we need not determine the precise boundaries of “surrounding textile structure,” for example whether it completely or mostly encircles the textile element, and if “mostly,” what percentage of encircling is required. See Pet.

We find that a person of ordinary skill in the art would not understand the portion of Zuckerman’s strip 13 in purple to surround the green blank 11 (textile element) under any reasonable construction of “surrounding textile structure.” Dr. Pastore testifies that “Zuckerman discloses two separate textile structures adjacent the blank—one on each side . . . they abut only two sides of Zuckerman’s blank, with each structure abutting only about a quarter of the blank’s periphery,” and opines that “a POSITA would not have understood these two separate structures, designated by purple in the figure above, to be a textile structure ‘surrounding’ the blank [shown in green].” Ex. 2003 ¶ 54. We find Dr. Pastore’s tesimony credible as it is consistent with Zuckerman’s Figure and with the plain and ordinary meaning of “surrounding” and with the Specification of the ’749 patent (particularly Figure 9).

“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. As discussed above, we do not agree that the claimed mathematical tree structure is limited to a single tree. See supra at 8–10 (§ II.B.2). Accordingly, we do not agree with Patent Owner’s arguments regarding Huttenlocher’s tree structure. Patent Owner does not otherwise challenger Petitioner’s contentions based on Broggi, Huttenlocher, and Brady.

“Prelim. Resp. 22–23 (citing Pet. 8; Ex. 2005 ¶¶ 71–72; Ex. 2009 ¶ 34); see id. at 23–29 (citing Ex. 1001, 1:43–45, 1:52–53, 1:58–2:5, 2:34–47, 3:47– 57, 4:3–6, 5:3–15; Ex. 2005 ¶¶ 74–81; Ex. 1015, 48; Ex. 1030, 150–151, 153, 515–517; Ex. 2011, 267–269; Ex. 2012, 2–3; Ex. 2015, 7:55–8:11, Fig. 5). 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. Additionally, dependent claim 2 suggests that “integration time” encompasses a frame of a scene because it recites, “[t]he device of claim 1,” slip op. at 12

“demonstrated sufficiently that there is a reasonable likelihood it would be successful in establishing Matsushima discloses or renders obvious limitation 1.3. 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
