Even if Ingle falls short of teaching structured application for its capacitor’s cathode, as Patent Owner argues, that does not undermine Petitioner’s challenge because Petitioner proposes using Hasei’s structured application (i.e., a droplet discharge device) to form the cathode of Ingle’s capacitor. See Pet. 24–25. Patent Owner’s additional argument that “Hasei contains no discussion of forming capacitors” (PO Resp. 36; see PO Sur-reply 17–18) is similarly flawed—it attacks Hasei individually, while ignoring Ingle’s capacitor teaching. We agree with Petitioner—the combination of Ingle and Hasei teaches structured application of the capacitor’s cathode. In addition, we disagree with Patent Owner that “Petitioner provides no reason why a POSITA would have extended Hasei’s method for producing its OLED to a capacitor.” PO Resp. 36; see PO Sur-reply 17 (asserting “pure conjecture”).

    “Based on the information presented, we find Petitioner has the better position. Patent Owner admits that joint vaporization means “two materials vaporize together.” Reply 21 (quoting Resp. 54). As Petitioner argues, “This is what Ma discloses.” Id. We agree with Petitioner that Ma describes a “two-component” electron transport layer having a “thickness with one value.” Id.; see Ex. 1007, 811 (reporting a “co-deposited” application of “BPhen:LiQ” that is “50 nm thick”). Ma’s disclosure, thereby, strongly “indicates that the two components were vaporized together––as opposed to creating a ‘macroscopically homogenous form’” prepared by sequentially vaporizing the individual components as Patent Owner “hypothesizes.” Reply 21 (citing Ex. 1020 ¶¶ 42–44; Ex. 2041 ¶¶ 155–157); see Resp. 54– 55; see also Ex. 1007, 811 (Ma’s description of its device fabrication, appearing in the third paragraph of the experiments section). Petitioner further advances evidence that “[p]reparing a layer that is ‘macroscopically homogeneous’ but potentially microscopically heterogeneous,” as Patent Owner postulates, “would introduce excessive variability and render the data noncomparable and unreliable, thus undermining the experiment’s purpose.” Reply 21 (citing Ex. 1020 ¶ 44); see Resp. 54–55. Patent Owner presents no counterargument or evidence that is persuasive to undercut Petitioner’s reasoning or evidence on that point. See Sur-reply 19–22.

Here again, Petitioner’s evidence on point stands uncontested. See Sur-reply 19–22 (declining to contest that point). On this record, therefore, we agree with Petitioner that, as to the relevant disclosure in Ma, “the most natural interpretation of ‘co-deposition’ for forming a layer, particularly when there is nothing to indicate that the materials” are “vaporized sequentially,” is that the materials are co-deposited by joint vaporization. Reply 22 (citing Ex. 1020 ¶ 46–51). We further agree that, “[u]nder a preponderance standard, Ma’s disclosures are sufficient to render joint vaporization at least obvious.” Id.

    “However, contrary to Dr. Almeroth’s testimony and Petitioner’s position, Xiao’s server already does not attempt to command vehicles to do things they cannot do. Xiao teaches that server 118 generates commands for command codes that exist and are settable in the vehicle. Ex. 1010 ¶¶ 102– 103. As such, if there is no corresponding automobile setting, then Xiao’s server would not list those command codes for retrieval and would not send a command based on that retrieved command code to control the automobile systems to achieve the operator’s desired settings because that command code is not in the database. Our understanding of Xiao is further supported by Dr. Almeroth’s testimony: By listing them in the table of automobile command code information 606, Xiao shows that there are particular settings compatible with particular automobiles and particular desired settings. Thus, Xiao demonstrates the necessarily present characteristic that certain settings (e.g., commands) are compatible with certain automobiles. Ex. 1009 ¶ 96 (emphases added). We note that Dr. Malek further explains “the nonsensical result achieved by the combination would be that Xiao’s server, at best, in response to the command request issued by the operator, could ‘look up’ a command code to apply a vehicle-specific setting to that automobile 112, only to find that there is ‘none.’” We agree with Dr. Malek that there is a “None” command code in Xiao’s database when Xiao’s database already stores settings that are known to be settable in a specific vehicle per the operator’s preferences.

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.

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.

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

    “Applicant’s foregoing computer security embodiment, utilizes two distinct communications channels and a random number generator in order to ensure that an authorized user of a computer system is notified that someone or something is seeking access to the computer system with his or her password. Moreover, Applicant’s foregoing invention is very cost effective as it employs substantially “off the shelf” and readily available components. Further, the use of a “secret” password, a “secret” substantially random number, and a “secret” second channel allows for multiple levels of security before access to the computer system is achieved and provides enhanced security over the prior art. Ex. 1005, 7:16–28. We do not agree with Patent Owner that these statements unequivocally support its position that Veneklase’s two-step authentication process is a principle of operation of its system. Rather, the quoted statements indicate that Veneklase’s use of two distinct communication channels and a random number generator are key features of Veneklase’s system that provide multiple levels of security and enhance security of that system. As modified Veneklase’s system still uses two distinct communication channels and a random number generator. Thus, to the extent that Veneklase’s enhanced security measures (i.e. two distinct communication channels and a random number generator) are a principle of operation of Veneklase’s system, the proposed modification does not destroy this principle of operation or render Veneklase’s system inoperable. Moreover, incorporating Jonsson’s teachings related to using an algorithm to create a new password would not destroy the principle of operation of Veneklase’s security system because it only changes how Veneklase accomplishes its goal of preventing unauthorized access to a computer system, rather than defeating its goal of preventing such access. See In re Mouttet, 686 F. 3d 1322, 1332 (Fed. Cir. 2012). Further, we do not agree that Plas-Pak (a routine decision11) supports Patent Owner’s contention that the proposed combination impermissibly changes Veneklase’s principle of operation as Patent Owner has not identified differences between the two authentication processes that would be “unlikely to motivate a person of ordinary skill to pursue” the proposed combination.

Petitioner does not propose modifying Veneklase to include Jonsson’s teachings solely because the security of the proposed combination is superior to the security in Veneklase. Rather, Petitioner asserts that “[a] POSITA would have been motivated to make such a combination because having only the one password transmitted via the computer system is more efficient and secure.” Pet. 31 (citing Ex. 1003 ¶ 91). The Petition explains how the combination is more efficient in that it requires only a single step which reduces the amount of time required for the authentication process. Id. We also agree with Petitioner’s reasoning that a person of ordinary skill in the art would have been “motivated to combine Veneklase and 11 “A routine decision is binding in the case in which it is made, even if it is not designated as precedential or informative, but it is not otherwise binding authority.” Patent Trial and Appeal Board, Standard Operating Procedure 2 (Rev. 11) 2 (July 24, 2023), available at https://www.uspto.gov/sites/default/files/documents/20230724_ptab_sop2_r ev11_.pdf.

Jonsson discloses a known algorithm and Veneklase discloses a system that is similar to Jonsson’s. In the absence of any evidence that applying Jonsson’s algorithm to Veneklase’s system is beyond the skill of a person of ordinary skill in the art, we agree that “the improvement is [no] more than the predictable use of prior art elements according to their established functions.” KSR, 550 U.S. at 401.” slip op. at 26
