    “Turning to the substantive issues, we find the District Court’s “mirror tracking mode” construction to be well-reasoned and supported by the record, and we therefore adopt that construction and its reasoning. As the District Court points out, both the “double the distance” and “same size” aspects of its construction are expressly discussed in the ’109 patent, which is incorporated in the ’110 patent. See Ex. 2008, 16 (citing Ex. 1021, 2:5–27, Figs. 5A, 5B), 40 (citing “same reasons set forth regarding the term ‘it appears to mimic a reflection of a mirror’” in support of construction of “mirror tracking mode”).

    “Post-institution, Patent Owner invites us to construe limitation 1[f]’s recitation of “mirror tracking mode” and limitation 1[c]’s recitation of “adaptive transformation mapping.” PO Resp. 9–14. Regarding the latter, Patent Owner explains that “[i]n the District Court Litigation, ‘adaptive transformation mapping’ was construed as ‘continuously variable transformation mapping’ and ‘transformation mapping’ was construed as a ‘selected set of image transformations.’” Id. at 14 (citing Ex. 2008, 14, 37; Ex. 2013 ¶¶ 25, 27).

    “persuasively address limitation 1[f]’s “mirror tracking mode.” In particular, Petitioner does not address persuasively the requirement, as explained in Section II.B above, that mirror tracking mode involves processing camera-captured images in a way that “maintains roughly the same size regardless of the user movement.” At odds with this requirement, Petitioner founds its case on an assertion that “Haan teaches the claimed mirror tracking mode” because “if the viewer is within 35 cm of the camera, a tracking mode is entered, applying resizing transformation.” Pet. 44 (emphasis added) (citing Ex. 1005 ¶¶ 75–76, 80–82, 90–94, 97; Ex. 1003 ¶¶ 205–210). The resizing transformation Petitioner references actually involves magnifying the user’s image by an amount that changes based on the user’s position relative to the camera, quite the opposite of maintaining image size regardless of the user movement. Ex. 1005 ¶¶ 75–76, Fig. 8. Thus, Petitioner’s initial position is unpersuasive. Petitioner’s shift to Haan’s “reflective mirror mode and conventional mirror period in the dual mode” is also unavailing. Reply 8. Consistent with Patent Owner’s arguments, Petitioner does not provide persuasive evidence that these operating states of Haan’s device involve any processing of camera-captured images. Sur-reply 13–14. To the contrary, Haan suggests that anytime its device provides an unmagnified image, it comes from a reflection off a physical reflective surface. See, e.g., Ex.1005 ¶ 76 (“This can be done for instance by using the device as a simple mirror, i.e. not displaying an image on the display device, but using the device in the reflective mode.”) (emphasis added), ¶ 92 (“a simple reflective mode, to act as a mirror”), ¶ 29 (“for a first range of positions, no image is displayed, whereby the reflective layer acts as a mirror, and for a second range of positions, the recorded image is displayed.”) (emphasis added). We also find unpersuasive Petitioner’s Reply arguments based on Haan’s disclosure of smoothly transitioning from “using the device as a simple mirror” (i.e., using a physical reflecting surface) to displaying a magnified image. Reply 11 (citing Ex. 1005 ¶¶ 76, 80). To the extent this may establish a point around the transition at which Haan’s system displays an image with relatively little magnification, it does not establish that Haan teaches, suggests, or renders obvious holding the displayed size roughly constant, “regardless of the user movement.” Indeed, given Haan’s focus on helping the user see things more clearly with image magnification, Petitioner’s argument that it would have been obvious to hold the size of the image constant is not persuasive. See, e.g., Ex. 1005 ¶ 4.” slip op. at 23

When the data carrier is switched into passive mode, the data carrier’s supply device generates the operating voltage for the electric circuit from the received high frequency energy. Id. at 6:5–9. Claim 1 of Tobergte does not suggest that the fixed station performs any search function. Instead, Tobergte’s fixed station receives both energy and data from the data carrier for the brief period that the data carrier is in the active mode. There is no indication that Tobergte’s fixed station is emitting signals to search for the data carrier. Instead, Tobergte claims a system in which the data carrier that “wakes up” the fixed station is then powered by the energy of the high frequency field transmitted by the fixed station. None of Tobergte’s other claims explicitly recites a search limitation. In other words, Tobergte describes and claims changing a conventional data carrier that transmits data only when interrogated (id. at 3:48−52) into a data carrier that begins transmitting energy and data first, when activated by a user (id. at 3:55−58, 3:65−67).” slip op. at 25

    “Specification concerning the terms “identify” and “detect” involve actions not recited in the claims does not change the fact that these different claim terms are presumed to have different meanings. The dictionary definitions of “detect” and “identify” are different. The use of the term “identify” in claims 3 and 8 and the use of a different term, i.e., “detect,” in claim 16 indicates that the claims 3 and 8 mean something different from claim 16.

    “Additionally, we are not persuaded by Patent Owner’s argument that Walker is not enabled, or that a POSITA would not have a reasonable expectation of success in combining Prust with Walker, because those arguments focus on features not required by the challenged claims of the ’868 patent. See Raytheon Tech. Corp. v. General Electric Co., 993 F.3d 1374) (Fed. Cir. 2021) (“In general, a prior art reference asserted under § 103 does not necessarily have to enable its own disclosure, i.e., be ‘self-enabling,’ to be relevant to the obviousness inquiry.”). Dr. Brogioli acknowledged that he never even analyzed whether the features of Walker that he argues are not enabling are required in the claims of the ’868 patent. Ex. 1032, 84:1-85:22 (testifying that he did not recall performing an analysis about whether the claims of the ’868 patent required allowing users to edit different parts of the same file at the same time, user collaboration, concurrency among user actions and editing, or locking a document). Moreover, other than pointing to the allegedly deficient teachings of Walker itself, Dr. Brogioli cites to no evidence of record in support of his testimony that a POSITA would not have a reasonable expectation of success in implementing Walker. See Ex. 2022 ¶¶ 66–74. But Walker itself is presumed to be enabling for what it teaches. See In re Antor Media Corp., 689 F.3d 1282, 1288 (Fed. Cir. 2012) (“[A] prior art printed publication . . . is presumptively enabling barring any showing to the contrary by [the] patentee.”). Rather than the unsupported testimony of Dr. Brogioli, we credit the testimony of Dr. Long, which is corroborated by other prior art, that the concepts disclosed in Walker, such as indicating that downloaded files are currently locked and unavailable to other users and multi-user editing, would have been familiar to programming students before 2005, and a POSITA would have been able to apply these well-known techniques with a reasonable expectation of success.

    “we are not persuaded by Patent Owner’s claim construction position that the claims require the virtual server to transmit information about files locally stored on the client device (in addition to virtual server files) as part of the fourth claim element. With regard to the claim language, we agree with Patent Owner that “the one or more files associated with the particular user storage account” recited in the fifth claim element finds antecedent basis in the prior recitation of “information relating to one or more files associated with the particular user storage account” in the fourth claim element. By its plain language, what this means is that at least some of the “information” that is transmitted from the virtual server under the fourth element must be related to the “userselected file” that is subsequently uploaded from the client device under the fifth element. Cf. Yamaha Corp. v. ESS Tech., Inc., 82 F.3d 435, 1996 WL 146499, *3 (Fed. Cir. 1996) (“By using a definite article ‘the’ to describe ‘output’ in the last phrase, Yamaha raises the inference that the term refers to the same value as in the first step.”). Thus, contrary to Petitioner’s arguments, we are not of the view that files referenced in the fourth and fifth elements are completely “distinct.” But this does not necessarily imply, as Patent Owner suggests, that the virtual server must already be in possession of information relating to locally stored files at the point of the transmitting step of the fourth element and prior to the uploading step of the fifth element. Indeed, there is nothing recited in the claims to suggest how the virtual server would come to know about files stored on the client device.” slip op. at 16

Ex. 1101, 3:36–41. In view of this definition in the Specification and the parties’ agreement in pre-institution briefing, we construed the phrase “depin a Fermi level of the metal electrical contact in the vicinity of the junction” as “passivate the semiconductor surface and reduce the effects of metal-induced gap states in the semiconductor” in our Institution Decision.

    “Although Patent Owner contends Dr. Goodnick’s declaration did not open the door for general questioning about metal oxides (PO Opp. 2–3), we agree with Petitioner that the proper scope of cross examination includes Dr. Goodnick’s understanding of what constitutes a distinct layer. A primary issue raised by Patent Owner against Petitioner’s challenge that Goodnick anticipates is that, notwithstanding its use of the term layer, Goodnick does not teach distinct layers that are required by the claim. See Section VI.B. One of those layers is a metal oxide layer (Ex. 1101, claim 1), in particular a titanium oxide layer (claim 6). In view of Dr. Goodnick’s checkerboard analogy in his declaration, it was proper for Petitioner to question Dr. Goodnick about the extent of materials in the checkerboard. Both parties argue there may be implications of Dr. Goodnick’s testimony for purposes of infringement litigation. See Pet. Opp. 4–6; PO Reply 3–4. We do not address those implications. The issue before us is whether Goodnick would have taught or suggested to a person of ordinary skill the limitations of the claims, which the parties agree include distinct layers of metal oxide and other semiconductor oxide. See Section VI.B. As Dr. Goodnick testified that his article did not teach such distinct layers, it was proper for Petitioner to explore Dr. Goodnick’s views concerning the composition of a layer during cross examination. In consideration of the above, Patent Owner’s motion to exclude the Goodnick Metal Oxide testimony is denied.” slip op. at 48
