    “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

    “Ex. 1005 ¶ 0111. Dr. Rubin testifies, succinctly, that “I do not believe that a [person of ordinary skill] would understand that Tajima uses the term ‘information regarding the key’ to refer to the key. If Tajima meant to say the ‘key,’ there would be no need to use the phrase ‘information regarding the key.’” Rubin II Decl. ¶ 41. He further testifies that “[w]hen Tajima wishes to refer to a ‘key,’ it does so directly” (citing many instances where Tajima makes explicit reference to keys). Id. ¶ 42 (citing Ex. 1005 ¶¶ 67, 70, 71, 75, 77, 86, 88, 89). We find Dr. Rubin’s reasoning on this issue persuasive. On the other hand, we find Dr. Bhattacharjee’s response less convincing. Bhattacharjee II Decl. ¶¶ 5–23. We find that he does not 5 Petitioner states that it does not rely on the doctrine of inherency to establish that this limitation is met by Tajima. Pet. Reply 2. understand that Tajima uses the terms “information regarding the key” and “key information” to refer to an encryption key. Id. ¶ 5 (citing Bhattacharjee I Decl. ¶ 103, 131). Lacking support for disclosure of an encryption key in Tajima itself, Dr. Bhattacharjee turns to other references, including Foster. Id. ¶¶ 7–9. Dr. Bhattacharjee testifies that “Foster’s use of the term ‘key information’ to describe information that includes the key and additional information . . . explains why Tajima did not just say ‘key’ when referring to the information attached to the data fragments.” Id. ¶ 8. Dr. Bhattacharjee’s testimony is unconvincing. In Foster, there is explicit disclosure of including the encrypted title key itself in the header extension. Ex. 1006 ¶ 66 (“As depicted, header extension 118 includes encrypted title key 112 . . . “). In contrast, Dr. Bhattacharjee cites no similar disclosure in Tajima. In fact, Dr. Bhattacharjee’s reliance on other references to support anticipation runs contrary to the rule that “[a] claim is anticipated only if each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.” Verdegaal Bros., Inc. v. Union Oil Co. of Cal., 814 F.2d 628, 631 (Fed. Cir. 1987) (emphasis added). We do not find Dr. Bhattacharjee’s testimony based on Foster and other references convincing of anticipation by Tajima. Nor do we find Petitioner’s alternative obviousness challenge based on Tajima persuasive. Pet. 22. The Petition includes a single-sentence explanation of this obviousness contention: “Even if Tajima had not disclosed that its key information includes the corresponding key, that would have been an obvious and conventional way to implement what Tajima discloses—i.e., a system that needs only the key information to decrypt data fragments and not additional key management infrastructure.” Id. (citing paragraph 104 of his initial declaration mirrors the Petition and provides no record citations to support his opinion of obviousness. Such unsupported expert testimony is entitled to little weight. “Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.” 37 C.F.R. § 42.65(a); PTAB Consolidated Trial Practice Guide 40 (Nov. 2019) (“Trial Practice Guide”) (“Opinions expressed without disclosing the underlying facts or data may be given little or no weight.”).6” slip op. at 17

    “Patent Owner responds that Petitioner “fails to demonstrate” a motivation to combine the references. PO Resp. 9. Patent Owner argues that “Tajima and Foster are directed to entirely different fields and to different problems.” Id. We disagree. As Petitioner points out, both Tajima and Foster are in the field of securing data, as is the ’116 patent. Pet. Reply 13–14 (citing Ex. 1005 ¶ 44; Ex. 1006 ¶ 3). Dr. Bhattacharjee testifies, “Tajima and Foster also both describe techniques for securing data using encryption and securely storing keys with encrypted data.” Bhattacharjee II Decl. ¶ 35 (citing Ex. 1005 ¶¶ 109–114; Ex. 1006 ¶¶ 64–71). Patent Owner argues Foster’s disclosure of a KEK would have been “redundant” to Tajima’s key-securing obfuscation technique. PO Resp. 18. We find this argument is unavailing. As Petitioner points out, Patent Owner’s argument “ignores Tajima’s vulnerability that Foster’s key-encryption addresses.” Pet. Reply 16. More specifically, “[r]equiring an attacker to obtain KEKs to decrypt Tajima’s encryption keys in addition to de-obfuscating them is not ‘redundant’ to only having to de-obfuscate them.” Pet. Reply 16 (emphasis omitted) (citing Bhattacharjee II Decl. ¶¶ 41–44). We find that Petitioner’s argument for combining the references is persuasive for the reasons given. Patent Owner further argues that Tajima and Foster address different problems and disclose solutions that are “fundamentally at odds.” PO Resp. 9–16, 25–27. Patent Owner asserts that “Foster’s system requires synchronizing the transmission of encrypted content packets with the keys used to encrypt those packets, so that each packet can be viewed immediately upon receipt.” Id. at 15 (emphasis omitted). Patent Owner attaching it to a different data fragment, the problem Foster sought to solve is the ‘need . . . for a key used to encrypt content to be itself encrypted, and transmitted as an integral part of the [same] content.’” Id. (alterations in original) (citing Ex. 1006 ¶ 7). We are not persuaded by this argument. As noted supra, for the reasons given, we find that both Tajima and Foster are in the field of securing data from unauthorized access. Pet. Reply 13. Furthermore, as Petitioner points out, we find that in Petitioner’s combination of Tajima and Foster, Tajima’s data (which does not require synchronization) is secured, not Foster’s. See Pet. 34–36 (providing reasons for encrypting Tajima’s keys); Pet. Reply 17–18 (“Synchronization of Foster’s data is irrelevant to Tajima-Foster because Tajima-Foster does not restore Foster’s data.”). Thus, we find that Patent Owner’s argument based on the need to synchronize Foster’s data for streaming is unavailing. We have considered Patent Owner’s other arguments and find them lacking. See, e.g., Patent Owner’s Sur-reply, which repeats the arguments that Tajima and Foster are in a “different field,” “fundamentally at odds,” “[i]n direct contrast,” and that applying Foster’s KEK teachings to Tajima would be “redundant.” PO Sur-reply 2–9.

    “Dr. Rubin explains that Kerckhoff’s Principle “holds that a cryptosystem should be secure, even if everything about the system, except the key, is public knowledge.” Rubin II Decl. ¶ 94. Citing this testimony, Patent Owner argues, “Shyu’s anti-piracy system is a prototypical attempt to achieve security through obscurity, to the extent it proposes to conceal or obscure the encryption algorithms.” PO Resp. 33. Petitioner does not persuasively respond to this argument. Pet. Reply 20–21. Petitioner argues that “Shyu does not use secret algorithms.” Id. at 20. Instead, according to Petitioner “Shyu selects from among known algorithms to secure different data segments.” Id. However, we find Shyu’s disclosure that “the scrambling algorithm and the key word for the source data are dynamically changed to effectively guard against piracy” is telling evidence that the underlying algorithms themselves are not secure, and therefore Kerckhoff’s principle applies here. See Ex. 1016, 1:37–39. We also find persuasive reasoning in Patent Owner’s assertion that “[c]ombining associated with maintaining multiple encryption algorithms and tracking encryption algorithm ‘metadata,’ without providing any substantial security.” PO Resp. 34–35. In sum, for the reasons given, we agree with Patent Owner that Petitioner fails to prove sufficiently that a person of ordinary skill would have been motivated to combine Tajima and Rivest. Further, Petitioner fails to demonstrate that even assuming that Tajima and Rivest would have been combined, a person of ordinary skill would have further combined their teachings with Shyu.” slip op. at 25

    “Alleged Objective Indicia of Nonobviousness (i) General Principles Before reaching a conclusion about obviousness, we consider evidence concerning objective indicia of nonobviousness. See Apple, 839 F.3d at 1048. For such evidence to have substantial weight, the patentee “must establish a nexus between the evidence and the merits of the claimed invention.” ClassCo, 838 F.3d at 1220. “[T]here is no nexus unless the evidence presented is ‘reasonably commensurate with the scope of the claims.’” Id. (quoting Rambus Inc. v. Rea, 731 F.3d 1248, 1257 (Fed. Cir. 2013)). The patentee “bears the burden of showing that a nexus exists.” WMS Gaming, Inc. v. Int’l Game Tech., 184 F.3d 1339, 1359 (Fed. Cir. 1999). A rebuttable presumption of nexus arises “when the patentee shows that the asserted objective evidence is tied to a specific product and that product ‘embodies the claimed features, and is coextensive with them.’” Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (quoting Polaris Indus., Inc. v. Arctic Cat, Inc., 882 F.3d 1056, 1072 (Fed. Cir. 2018)). Whether a rebuttable presumption of nexus arises “turns on the nature of the claims and the specific facts.” Teva Pharms. Int’l GmbH v. Eli Lilly & Co., 8 F.4th 1349, 1362 (Fed. Cir. 2021). The presumption analysis should consider the unclaimed features in the product tied to the objective evidence to assess their significance and impact on the correspondence between the patented invention and the product. Quanergy Sys., Inc. v. Velodyne Lidar USA, Inc., 24 F.4th 1406, 1418 (Fed. Cir. 2022). When, “for example, the patented invention is only a small component of the product tied to the objective evidence,” and thus the product is not coextensive with the patented invention, “there is no presumption of nexus.” Henny Penny Corp. v. Frymaster LLC, 938 F.3d 1324, 1333 (Fed. Cir. 2019). Absent a presumption of nexus, the patentee may prove nexus by showing that the objective evidence resulted directly from “the unique characteristics of the claimed invention.” Fox Factory, 944 F.3d at 1373–74; see In re Huang, 100 F.3d 135, 140 (Fed. Cir. 1996). For example, “[a] prima facie case of nexus is generally made out when the patentee shows both that there is commercial success, and that the thing (product or method) that is commercially successful is the invention disclosed and claimed in the patent.” Demaco Corp. v.

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

    “Even a small amount of power that may be consumed by incorporating Cole into Tobergte likely exceeds the power consumed by Tobergte’s configuration in which the computer and oscillator are disconnected from power. Nevertheless, neither party provides a specific power consumption analysis. On this issue, we weigh Dr. Phinney’s testimony over Patent Owner’s attorney arguments and determine that Patent Owner has not sufficiently supported its contention that Cole teaches away from Tobergte on this basis. We determine that a person of ordinary skill would have had reason to combine the teachings of Tobergte with those of Cole to provide a system that detects the presence of data carriers automatically without the need for the user to activate the data carrier with a switch.” slip op. at 16

    “Patent Owner asserts that in Petitioner’s analysis of claim 16, “Petitioner reads out any distinctions between ‘at least a subset’ and ‘a subset.’” PO Resp. 45. Petitioner responds that “[t]he Board should reject Patent Owner’s argument that ‘the subset’ must be a ‘proper subset,’ i.e., a set that is less than the full set of outgoing data.” Pet. Reply 5. Petitioner cites dictionary definitions and other additional authorities to support this conclusion. Pet. Reply 5–6 (citing, e.g., Exs. 1022, 1023, 1024). For example, A Dictionary of Computing defines “subset” as “[a] set T whose members are all members of S,” and contrasts this with a “proper subset.” Ex. 1023, 3. Petitioner further points out that the antecedent basis of “at least a subset” for “the subset” in claim 16 supports its construction. Pet. Reply 6. In our Final Written Decision, after considering Petitioner’s evidence and the language of the claim, we found that the references to “subset” in claim 16 should be construed broadly enough to read on providing any portion of the outgoing data, up to and including all the data, and not a proper subset. FWD 24–25. For the reasons summarized above and those given in our Final Written Decision, we find that the term “subset” in claim 16 does not limit the claim to a “proper subset,” i.e., the claimed subset may include all the members of the set.” slip op. at 16

    “Applying the Federal Circuit’s “flexible” standard, we find that for the reasons given that Petitioner demonstrates a motivation to combine Sikdar and the APA, as proposed by Petitioner, with a reasonable expectation of success. We disagree with Patent Owner’s arguments and find that a person of ordinary skill would have been motivated to add Sikdar’s NAT/PAT capability to the prior art network system of Figure 18, disclosing a software-based firewall. Pet. 55–58; Pet. Reply 23–25. As Petitioner points out, Sikdar’s RSP “does not include any NICs . . . , which are a separate hardware component.” Pet. Reply 24. We agree with Petitioner that Patent Owner’s argument is not convincing. More importantly, however, Patent Owner’s argument fails because in Ground 3, Petitioner does not propose combining “any device containing two NICs with the APA.” Id. Petitioner proposes combining “the RSP’s NAT/PAT functionality with the APA.” Id. at 24–25 (citing Pet. 55–58) (emphasis added). “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” In re Keller, 642 F.2d 413, 425 (CCPA 1981); see also In re Sneed, 710 F.2d 1544, 1550 (Fed.

Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (citation omitted). We concluded, in our Final Written Decision, that Patent Owner had failed to meet its burden. FWD 47–50. We agreed with Petitioner that Patent Owner had failed to establish the required nexus to its claims. Id. at 49. We agreed also that Patent Owner had not provided convincing evidence supporting the existence of such objective indicia. Id.
