  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Petitioner argues that one of ordinary skill in the art relevant to the challenged claims, as of the earliest claimed priority date, “would have had at least a bachelor’s degree in a healthcare field as well as 1–2 years of experience with health information technology, including specific experience with computer-based systems for recording, tracking, and analyzing patient health information.” Pet. 6 (citing Ex. 1012 ¶ 36). Petitioner’s description of the level of ordinary skill in the art is supported by the testimony of Petitioner’s declarant, Dr. Bryan Bergeron. Ex. 1012 ¶ 36. Patent Owner does not oppose Petitioner’s definition of a person of ordinary skill in the art. See generally PO Resp.; Ex. 2005 ¶ 32. On the full record, we determine Petitioner’s proposed level of skill comports with the qualifications a person would have needed to understand and implement the teachings of the ’142 patent and the prior art of record.

    “We agree with Petitioner that the Specification supports construing “selection” as including inputs to a user interface, thereby “assigning” a client to a provider within the system. For example, the Specification describes a user interface including selection components. Ex. 1001, 10:45– 48 (“the user interface . . . may display . . . selection or display components”), 12:19–22 (authorized users may make selections by doubling tapping a touchscreen). The Specification further discloses that the “administrators may have complete access to the service providers and the clients to assign the clients to individual service providers through the user interface.” Id. at 11:13–18 (reference numerals removed, emphasis added). Taken together, we agree with Petitioner that assigning clients in response to selections of a user interface is consistent with the plain and ordinary meaning of the claims and the Specification. We decline to read Patent Owner’s additional limitations of “deliberate and active choice” into the claim, because these additional limitations lack support both in the claim language and the Specification. We do agree with Patent Owner’s argument that assigning and selection must be distinct elements, because they are separately listed and assigning happens in response to selection(s).” slip op. at 9

    “We agree with Patent Owner that the Specification defines “projected closure date” as the date at which a goal will end. However, we agree with Petitioner that this definition is not limited to final goals, and would include the end date of any goal, including intermediate goals. Accordingly, we interpret “projected closure date” as the date at which any goal will end. We apply that definition below.” slip op. at 12

    “Patent Owner responds that “Petitioner does not identify any selection made by Douglas’s administrator which may result in assignment of a provider.” PO Resp. 15 (citing Pet. 19–20; Ex. 1002, 6:33–7:13, Fig. 2). First, Patent Owner construes “selection” as “a deliberate and active choice by an administrator,” and argues that “Douglas discloses no such selection.” Id. at 15–16 (citing Ex. 1001, 11:13–18; Ex. 2005 ¶ 66). Instead, “Douglas’s administrator merely inputs pre-determined information from the prescription form” that the physician provided and thereby selected. Id. at 16 (citing Ex. 1002, 6:33–7:13, Fig. 2; Ex. 2005 ¶ 67). We find this argument not commensurate with the claim scope. As discussed above in claim construction, we decline to read Patent Owner’s additional limitations of “deliberate and active choice” into the selection limitation as lacking support both in the claim language and the Specification. Supra, Section III.C.1. Second, Patent Owner argues that Douglas does not teach assigning “in response to” an administrator’s selection. PO Resp. 16–17. Instead, Patent Owner argues that Douglas’s “information entered by the case advisor was provided by the physician.” Id. (citing Ex. 1002, 6:33–7:16). Again, we find this argument not commensurate with the claim scope, as the claim does not require a single assignment of client to provider. In other words, even if Douglas’s prescription information qualifies as a first assignment of client to provider, Douglas teaches the administrator using the same information to assign the client to a provider within the system, thereby meeting the required claim limitation.” slip op. at 16

    “C. Level of Ordinary Skill in the Art Factors pertinent to determining the level of ordinary skill in the art include (1) the educational level of the inventor; (2) the type of problems encountered in the art; (3) prior-art solutions to those problems; (4) the rapidity with which innovations are made; (5) the sophistication of the technology; and (6) the educational level of workers active in the field. Envtl. Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696–97 (Fed. Cir. 1983). Not all factors may exist in every case, and one or more of these or other factors may predominate in a particular case. Id. These factors are not exhaustive, but merely a guide to determining the level of ordinary skill in the art. Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007). Moreover, the prior art itself may reflect an appropriate skill level. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Petitioner asserts that a person of ordinary skill in the art at the ’336 patent’s effective filing date would have had “a bachelor’s degree in mechanical engineering, electrical engineering, optics, or physics with at least three years of experience working in the design of LED lights or lighting fixtures; a master’s degree in one of the above disciplines with at least two years of experience; or equivalent experience.” Pet. 14 (citing Ex. 1004 ¶¶ 26–29).

    “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, “its proponent must establish a nexus between the evidence and the merits of the claimed invention.” ClassCo, Inc. v. Apple, Inc., 838 F.3d 1214, 1220 (Fed. Cir. 2016); see Ancora Techs., Inc. v. Roku, Inc., 140 F.4th 1351, 1361 (Fed. Cir. 2025) (noting that the Board did not err by requiring “a nexus to the challenged claims as opposed to the patent as a whole”). “[T]here is no nexus unless the evidence presented is ‘reasonably commensurate with the scope of the claims.’” ClassCo, 838 F.3d at 1220 (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, 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” slip op. at 76

    “We have considered Petitioner’s arguments and Dr. Shamos’s testimony in light of Oborne’s disclosure, but find Patent Owner’s arguments and Dr. Malek’s responsive testimony to be more persuasive. We agree with Dr. Malek that, in Oborne, “device fingerprinting simply refers to identifying a device and the user associated with that device.” Ex. 2009 ¶ 111. Specifically, paragraph 26 of Oborne (quoted above) discloses authentication of a user, where “device fingerprinting” is utilized to verify a user’s identity where a user exclusively uses a client device such as a smartphone or laptop computer. Ex. 1011 ¶ 26 (emphasis added). The use of the device fingering for determining the device identity in order to authenticate a user is corroborated by the disclosures in paragraph 47 of Oborne which refer, in part, to the “<client_details” which can include a “<client_type>smartphone” and “client_fingerprint>font list, MAC address, memory size, memory.” Id. ¶ 47 (emphasis added). So, contrary to Petitioner’s arguments, we do not discern any disclosure in Oborne that “device fingerprinting” ties a token to a particular device. See, Ex. 1011 ¶¶ 26, 47. Rather, Oborne’s disclosures support Dr. Malek’s testimony that, contrary to Petitioner’s position, “device fingerprinting could be used to limit a token to a set of fingerprinted devices, such as each device belonging to the user.” Ex. 2009 ¶ 113. Moreover, Petitioner (and Dr. Shamos’s) statement that “the first device’s fingerprint would not match” the fingerprint for the second device merely provides a possible outcome of device fingerprinting, but does not explain why one of ordinary skill would be motivated to use device fingerprinting to make the “second device’s token . . . invalid in the first device,” or make the “token for the second device . . . a new credential,” or point to disclosures in Oborne that would support such a motivation. See Pet. 34–35; Ex. 1005 ¶ 228. Thus, we find that Petitioner’s contentions as to this limitation lack sufficient specificity to explain how Oborne teaches the limitation. See Netflix, Inc. v. DivX, LLC, 84 F.4th 1371, 1377 (Fed. Cir. 2023) (“Ultimately, it is the petitioner’s burden to present a clear argument.”); Intelligent Bio-Sys. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369 (“It is of the utmost importance that petitioners in the IPR proceedings adhere to the requirement that the initial petition identify ‘with particularity’ the ‘evidence that supports the grounds for the challenge to each claim.’ ” (quoting 35 U.S.C. § 312(a)(3))). We further agree with Patent Owner that Oborne’s disclosure of “device fingerprinting” is limited, and does not describe how it would be implemented for a user with two devices. See PO Resp. 41–42. Therefore, Dr. Shamos’s cited Declaration testimony is “conclusory, adds little to the conclusory assertion for which it is offered to support, and is entitled to little weight.” Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB August 24, 2022) (precedential); see also 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”).” slip op. at 41

Although Stafford discloses that the key signatures may be copied from the display or delivered to the user via email, Petitioner does not expand upon whether the user would also copy the image from the display, whether the image would be provided via email as well, or provide any other explanation other than that the image credential would be provided with the scannable key signatures. Ex. 1012 ¶¶ 97, 99; Pet. 60. Although a credential image would presumably need to be retrieved or generated in some manner, and associated with the key signatures in some manner, Petitioner also does not sufficiently explain how this would work in the proposed combination, or how the user would transmit the scannable key signature to the recipient. Although proof of physical or bodily incorporation is not required, a satisfactory explanation of “how the combination of the . . . references [is] supposed to work” is necessary to support “a conclusion that a relevant skilled artisan would have been motivated to make the combination and reasonably expect success in doing so.” Personal Web Techs., LLC v.

    “We are not persuaded by lululemon’s attempt to equate the term “channel” in that passage with an open-periphery configuration. Nowhere does that passage indicate that the “channel” has an open-periphery. Instead, lululemon merely presumes, without support, that channels are open-periphery structures. More accurately, the terms “tunnel” and “channel” in the passage cited by lululemon are used synonymously. That is made clear by the overall context of the ’046 patent at issue, which is directed to how tubular rib structures 126 are formed by “first” and “second” curved portions 416 and 418 that are “knitted together” to define “hollow tube 112.” See Ex. 1001, 10:16–11:14, Figs. 4, 5 (emphasis added). In particular, the sentence cited by lululemon describes hollow tube 112 as being “disposed between” first and second curved portions 416 and 418, which Figures 4 and 5 of the ’046 patent clearly depict in a closed-periphery configuration. See id. at 10:66–11:3, Figs. 4, 5. Moreover, the very next sentence expressly describes that hollow tube 112 has “a generally cylindrical or elliptical shape” wherein “[t]he diameter of one hollow tube and the diameter of other hollow tubes may differ in some embodiments.” Id. at 11:3–14 (emphases added). We are not aware of any open-periphery channels being described as having a cylindrical or elliptical shape, nor are we aware of such a channel being described as having a diameter. Thus, lululemon’s proposed claim construction ignores the context surrounding the ’046 patent’s description of the tubular rib structures when it describes them as having the configuration of a tunnel or channel.” slip op. at 10

    “We agree with Nike, given our construction of the claimed “tubular structures.” As shown in annotated Figures 1, 3, and 4 of Good (reproduced below), Good discloses a sock 12 having rib portions 22 (red) and webbed areas 24 (green). See PO Resp. 19. lululemon contends that Good’s rib portions 22 meet the claimed “tubular structures” because each rib portion 22 “roll[s] substantially together in the relaxed condition” and “has the shape of a tube, namely an elongate hollow structure.” Pet. 29–30. In support, lululemon points to Good’s Figure 3 (reproduced below center) as allegedly showing the tubular shape of Good’s rib portions 22. Id. at 30. Annotated Figure 3 is a vertical cross-section of rib portions 22 (red) shown in Good’s Figure 1. But, as Nike correctly notes, Good’s rib portions 22 are “C-shaped knitted portions,” which when stretched, go from an essentially C-shaped configuration (Figure 3) to a relatively flat, linear configuration (Figure 4). PO Resp. 19–20 (citing Ex. 2006 ¶¶ 48–49). Nowhere does Good disclose that the ends of C-shaped rib portions 22 ever meet and remain in a closed periphery configuration to form a hollow tube per our construction of “tubular structures” (as discussed above in Section II.B). In at least this way, Good’s C-shaped rib portions 22 differ from the claimed “tubular structures.”7 Thus, we find that Good does not disclose or otherwise suggest the claimed “tubular structures,” as properly construed, meaning that lululemon fails to demonstrate, by a preponderance of the evidence, that Good either anticipates claims 1–3, 7, 16–18, and 20, or, alternatively, renders obvious claim 3.” slip op. at 16

Dec. 10–12. During the trial phase, lululemon’s expert likewise agreed, conceding (on cross-examination) that Munsing only discloses non-tubular structures. See Ex. 2007, 40:9–41:11 (“Q [by Patent Owner’s counsel]: So you agree that . . . Munsing only discloses a nontubular rib? A [by lululemon’s expert]: That’s what I said.”).

Compare PO Resp. 25–26 (noting the admission of lululemon’s expert), with Pet. Reply 1–26 (addressing only Grounds 1 and 3, while omitting any mention of Ground 2, which is based on Munsing). Nor does lululemon ever dispute the preliminary findings in our Institution Decision as to why Munsing is not an anticipatory reference. Compare Inst. Dec. 10–12, with Pet. Reply 1–22.

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. For reasons already discussed, we find these arguments unconvincing. In sum, we find for the reasons given that Petitioner has proved by a” slip op. at 21

    “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
