      “Alternatively, to the extent Blain may not disclose that its instrument guide 14 “extend[s] outside a patient’s body to a medical practitioner,” Petitioner argues that it would have “been obvious based on common sense and the general knowledge of POSAs to make the length of the shaft of instrument guide 14 sufficiently long so that the physician would not have to stick his or her hand inside the incision location to insert the implant between the vertebrae.” Pet. 53 (citing Ex. 1002 ¶ 123). According to Petitioner, one of ordinary skill in the art would have understood such a configuration to “provid[e] the known benefit of allowing the physician to maneuver and manipulate the delivery tool without having to insert his or her hand into the patient’s body to deliver and position the implant.” Id. (citing Ex. 1002 ¶ 124). And, relying on the declaration testimony of Mr. Culbert, Petitioner contends that one of ordinary skill in the art would have “had a reasonable expectation of success in modifying the instrument guide 14 such that its handle 20 and shaft 22 extends outside the patient’s body, as this involved nothing more than lengthening the proximal shaft 22A and/or distal shaft 22B.” Id. at 54 (citing Ex. 1002 ¶ 126); see also Ex. 1004, 5:4–6; Ex. 1005 ¶ 21 (Blain disclosing that “the relative lengths between the proximal shaft 22A and the distal shaft 22B can vary”).” slip op. at 17

In the Preliminary Response, Patent Owner contends that a skilled artisan would have had “a bachelor’s degree in electrical engineering, computer science, computer engineering, physics, or a related subject, and two to three years of work experience in digital imaging.” Prelim. Resp. 30 (citing Ex. 2005 ¶ 82). For purposes of this Decision, and based on the current record, we adopt Petitioner’s characterization of the level of skill for one of ordinary skill in the art. However, we note Patent Owner’s proposed characterization of a skilled artisan is not meaningfully different than the one proposed by Petitioner. Because we find the parties’ characterizations to be consistent with the ’158 patent and the asserted prior art, our analysis below applies Petitioner’s characterization for the level of ordinary skill in the art.” slip op. at 9

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner

      “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

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundInstituted

      “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

      “claim 15). We agree that the Specification supports Patent Owner’s construction. Although Petitioner bases its construction on extrinsic evidence, Petitioner argues that its construction “is consistent with” the intrinsic evidence, which, according to Petitioner, “indicates a sole is optional.” Pet. 31. A sole is optional, Petitioner argues, because the Abstract of the ’511 patent states that “[t]he footwear may include an upper and a sole structure.” Pet. 31 (quoting Ex. 1001, Abstr. (Petitioner’s emphasis)). We are not persuaded. Petitioner reads too much into the sentence it quotes from the Abstract and its use of the word “may.” Indeed, by Petitioner’s logic, both the upper and the sole structure would be optional and footwear would lack any required structure. Petitioner also argues that “[o]ther intrinsic evidence” supports its construction. Pet. 31–32 (citing Ex. 1053, 4:55–58; Ex. 1002 ¶92). The alleged intrinsic evidence, however, is an unrelated patent, US 2,675,631, which purportedly was cited during the prosecution of the ’511 patent. Id. This argument is undeveloped by Petitioner. First, Petitioner fails to substantiate that US 2,675,631 is cited in the prosecution history, merely asserting it as fact without pointing to supporting evidence. See id.

      “Mr. Lett testifies that Mahajan “allows for its server media abstraction module to be located in a processing device that may not typically be labeled a ‘server,’ such as remote control 14 of Danciu.” Ex. 1198 ¶ 9 (citing Ex. 1102 ¶ 162; Ex. 1114 ¶ 17). Yet, both Petitioner and Mr. Lett fail to explain how or why a person of ordinary skill in the art would take the distributed nature allowed by Mahajan and completely flip its teachings to put a client or remote device process on a server device. Mr. Lett further fails to explain how or why one would want to move Mahajan’s abstraction layer in the first place. Although Mahajan teaches that its system can operate in a distributed environment, based on the explicit disclosure of Mahajan and its examples, we do not understand “distributed” to mean that (i) the server processes can occur on client devices and (ii) that client processes can occur on server devices. See Ex. 1114 ¶¶ 51, 58, 60, 61, 76, 77. Rather, we understand “distributed computing environments” to encompass “an environment where tasks are performed by remote processing devices that are linked through a communications network” because that is what is taught in Mahajan. Id. ¶ 58. Our understanding is supported by the testimony of Mr. Lett. See Ex. 1198 ¶ 8 (reciting the explicit disclosure in Mahajan). It is clear, based on the plain reading of Mahajan, that the distributed environment indicates that server 202 and client 204 could be located in different locations, but would be linked through a communications network where user-command 230 flows from client 204 to server 202. See Ex. 1114 ¶ 35, Fig. 2. At no point does Mahajan teach or even suggest that user-commands 230 would flow from server 202 to client 204 as proposed by Petitioner. Additionally, we find insufficient reason in the record to explain Petitioner’s argument appears to be based completely on hindsight bias created in view of the challenged claims. Therefore, we find little credibility in Mr. Lett’s testimony regarding the change or in Petitioner’s position. To the contrary, we find Dr. Wicker’s testimony to be credible because it is supported by the disclosures in both Mahajan and Danciu. Specifically, we agree with Dr. Wicker, who testified that Mahajan does not describe an abstraction layer as ever being on “a server in the network.” See Ex.1197, 18:21–24. We also find Dr. Wicker’s testimony credible when he explained that even if Mahajan’s abstraction layer were implemented on a server in a network as posited by Petitioner, it still would not result in the claim mapping proposed by Petitioner.
