    “In our Decision on Institution, we adopted the following definition for one having ordinary skill in the art at the time of the invention of the ’093 patent: one who “would have had a bachelor’s degree in electrical engineering, computer engineering, computer science, or a related field, and . . . two years of experience in the research, design, development, and/or testing of touch and/or proximity sensors, human-machine interaction and interfaces, and related firmware and software, or the equivalent, with additional education substituting for experience and vice versa.” Dec. on Inst. 22 (quoting Pet. 10 (citing Ex. 1002 ¶ 47)). This definition mirrors what Petitioner proposed, except we excised the phrase “at least” which modified the years of experience as that language is vague and open-ended. Id. Patent Owner proposes a different definition for one of ordinary skill in the art, but does not specifically address any deficiencies in Petitioner’s Petitioner’s obviousness arguments “are not affected [by] differences in the definitions.” Id. (citing Ex. 2056 ¶ 10). Because Petitioner’s definition of the level of skill in the art (excluding “at least”) is consistent with the ’093 patent and the asserted prior art, we maintain it for purposes of this Final Written Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); GPAC, 57 F.3d at 1579; In re Oelrich, 579 F.2d 86, 91 (CCPA 1978).

    “We agree with Petitioner and conclude that Patent Owner incorrectly attempts to exclude touching from the claims. Patent Owner incorrectly focuses on the term “propinquity” itself and ignores the surrounding claim language. That is, whether propinquity and touching are mutually exclusive, as Patent Owner argues, is inapposite. The claims do not recite having a of propinquity,” without reciting a lower bound. E.g., Ex. 1001, 67:48–51 (emphasis added). The plain meaning thus includes a degree of propinquity, and being closer. The Specification supports this conclusion by disclosing detecting a user’s fingers when they touch, or are located in propinquity to, a surface. See, e.g., id. at 48:48–52 (“[A] position of a user’s fingers is detected by means of a touch responsive input functionality and/or propinquity responsive input functionality.”), 49:49–52 (“When the user’s fingers touch, as in FIG. 20B, or is located in propinquity to, as in FIG. 20A, plate 1508, the light reflected from the fingers is detected by one or more of detector elements 1504 . . . .”), 50:25–28 (“When the user’s fingers touches, as in FIG. 21B, or is located in propinquity to, as in FIG. 21A, plate 1508, the light reflected from the fingers is detected by one or more of detector elements 1504 . . . .”), 50:58–61 (“When the user’s fingers touch, or are located in propinquity to, plate 1508, the light reflected from the fingers is detected by one or more of detector elements 1504 . . . .”).

    “Having reviewed the parties’ arguments, we agree with Petitioner and conclude that the claims do not require a detector assembly to be physically separate from (i.e., not interspersed with) a pixel array. See, e.g., Ex. 1001, 66:65–67:11. This is not to say that a detector assembly (e.g., detector elements) and the pixels of a pixel array are not distinct components, because they are in that they are separate components and perform different functions. See, e.g., id. at 4:44–54 (disclosing that detector elements detect electromagnetic radiation), 9:50–55 (disclosing display devices including a pixel array operative to provide a visually sensible output), 36:41–46 (disclosing discrete single-element detector elements that are commercially available). Rather, the gravamen of the parties’ dispute is whether claim 15 covers embodiments of the ’850 patent where detector elements are interspersed (at least along an edge) with pixels in a pixel array. Nothing in the claim language or Specification precludes claim 15 from covering those embodiments. Id. In addition, claim 15 recites the location of a detector assembly as being “arranged at least one edge of a viewing plane defining plate.” Id. at by including being behind, about, or along an edge within its scope. Ex. 1001, 42:61–67. Moreover, the ’850 patent illustrates that detector elements can be located, inter alia, along and behind an edge while being interspersed in a pixel array. See id. at Fig. 18F (showing detector elements 1324 along and behind an edge of plate 1328); cf. In re Aslanian, 590 F.2d 911, 914 (CCPA 1979) (considering drawings for what they reasonably disclose to one of ordinary skill in the art). We find unavailing Patent Owner’s reliance on Becton. First, unlike in Becton where the same structure was relied upon, detector elements and a pixel array are separate components that perform separate functions. Becton, 616 F.3d at 1255 (accused infringer asserting “that the spring means and the hinged arm can be the same structure”); Ex. 1001, 4:44–54, 9:50–55, 36:41–46. Second, in Becton, the claims required one claim element to be “connected to” another claim element, which would be nonsensical if they were the same structure. See Becton, 616 F.3d at 1255. Here, claim 15 recites a location of a detector assembly (i.e., “arranged at least one edge of a viewing plane defining plate”), which is compatible with the detector assembly being interspersed in a pixel array. See, e.g., Ex. 1001, Fig. 18F.” slip op. at 22

    “As discussed above, we agree with Petitioner that Kirchhoff discloses the use of SSL, a protocol that uses data encryption (Ex. 1005, 8:47–49). We also agree with Petitioner that Krtolica discloses the use of HTTP protocols on port 80 (Ex. 1004, 6:23–24), and does so with a goal of maintaining high network security (id. at 1:7–10, 2:33–36). As Kirchhoff discloses, and Dr. Lavian’s testimony supports, one of ordinary skill in the art would have been aware that port 443, rather than port 80, would be used for secure web connections using SSL, which includes the use of encryption, and this would have resulted in enhanced network security. See Ex. 1005, 3:38–41; Ex. 1002 ¶¶ 52, 69, 108. As Dr. Lavian testifies, SSL/TLS was the most widely deployed security protocol in the world and the well-known use of SSL in HTTPS protocol enables secure web-based e-commerce. Ex. 1002 ¶¶ 69, 108; Ex. 1035 ¶ 8; Ex. 1006, 5. And, Krtolica has a stated goal to maintain network security. Ex. 1004, 1:7–10, 2:33–37. We find this evidence provides a sufficient rational underpinning in support of obviousness for combining the teachings of Krtolica and Kirchhoff. See KSR, 550 U.S. at 418. Owner’s arguments that use of encryption in SSL was optional and adding encryption would allegedly undermine network security. Nor do we find persuasive the argument that the Petitioner’s motivation to combine based on efficiency is insufficient, because Petitioner relies on another rationale for the combination of Krtolica and Kirchhoff, that is, enhanced network security, also discussed above. We additionally do not find persuasive Patent Owner’s arguments that combining Krtolica and Kirchhoff would render the system of Krtolica unsatisfactory for its intended purpose because, as Petitioner argues, this assertion is contradicted by the state of the art at the time. See Pet. Reply 9. As discussed above, Dr. Lavian explains that there were known systems having firewalls with SSL traversal at the time of the invention. Ex. 1002 ¶¶ 53, 59–65; Ex. 1035 ¶ 20; Ex. 1014. Moreover, the ’978 patent uses encryption with firewalls using a single-port protocol, and Patent Owner does not direct us to any disclosure in that patent that indicates that the use of encryption with a single-port protocol was inventive in that the system, or that encryption had to be done in a special manner.
