“the ’556 application does not provide written description support for the proposed substitute claims. For limitations 23e, 30e, and 37e of respective independent proposed claims 23, 30, and 37, Patent Owner points to paragraphs 11, 37, 60, 78, 83–85, 90, 109–113, 119–130, 150, and Figure 11 of the ’556 application as providing written description support. MTA 6–7, 10, 14–15; Reply 2–3. Reviewing these paragraphs, however, we find no description of the subject matter recited in limitation 23e, which recites “responsive to determining that the [first] variation of the soft information change how the hard information is displayed at the client device, determine a second variation of the soft information.” Nor do we find in those passages written description of the subject matter recited in the similar language of limitations 30e and 37e. Specifically, paragraphs 11 and 37 of the ’556 application address prediction of the response message expected from the client device (similar to limitations 23h–23j, 30h–30j, and 37h–37j, which were added in the MTA to the original claims of the ’759 patent). Paragraphs 60, 78, 83, and 84 describe specific ways to vary soft messaging to establish secondary communications between a server and a client device to detect the presence of a malicious application. Paragraph 85 describes a priori recording of soft information variations to create large sets of composite (hard and soft) messages to be transmitted together. Paragraph 85 also states that, alternatively, the hard and soft messages may be transmitted separately. Paragraph 90 mentions use of “spaghetti” code and soft formatting to make it difficult for malicious applications to alter, replace, or counterfeit in real time. Paragraphs 109 to 113 mention various ways to vary soft information and soft messaging, such as varying or selecting different characters sets, font type, color, or weight, and point sizes from session to session, and predicting the response from the client device to compare with the actual response. Paragraphs 119 to 125 and Figure 11 address soft messaging using un-rendered page elements, and paragraphs 126 to 130 describe soft messaging using graphical elements. Paragraph 150 discusses identifying compatible soft information and selecting a variation of soft information to prevent malicious applications from reverse engineering the soft messaging used to validate communications. None of these disclosures describe the “trial and error” or “testing” approach of limitations 23e, 30e, and 37e in which, responsive to determining that a first variation of the soft information changes how the hard information is displayed at the client device, the security processor creates a second variation of soft information (which is included in the message to the client device if it does not vary how the hard information is displayed—see limitations 23f–23g, 30f–30g, and 37f–37g) to prevent a malicious application from interacting with the hard information. Accordingly, Patent Owner fails to meet its burden to show that limitations 23e, 30e, and 37e of independent proposed substitute claims 23, 30, and 37, as presented in the Motion to Amend, have written description support in the ’556 application, as required under 37 C.F.R. § 42.121(b)(2).” slip op. at 11

“Conclusion As explained above, Petitioner’s proven time of conception and communication of the subject matter of “the invention disclosed to the respondent” is “February 14, 2014 4:04:17 PM EST.” Respondent’s proven time of conception of the subject matter of “the invention disclosed to the respondent” is “Feb 14, 2014 12:55 pm.” If Respondent’s time is Eastern Standard Time, then Respondent’s conception precedes Petitioner’s conception and communication by 3 hours and 9 minutes. If Respondent’s time is Pacific Standard Time, it precedes Petitioner’s conception and communication by 9 minutes. Accordingly, Petitioner has not shown that Bradley Burnam conceived of “the invention disclosed to the respondent” prior to Marc Selner’s conception of that same subject matter, and Petitioner has not shown that Bradley Burnam communicated “the invention disclosed to the respondent” to Marc Selner prior to Marc Selner’s conception of the same subject matter.

“skilled artisan to have its “ordinary and customary meaning[],” allegedly “a stream of data bytes that can be read and written (among other common operations).” PO Resp. 3. But as noted by Petitioner (Pet. Reply 3–4), the only intrinsic evidence cited by Patent Owner does not support its proposed construction in the context of the ’613 patent; rather, such evidence favors Petitioner. See PO Resp. 4 (citing Ex. 1001, 2:35–45 (a “‘file is accessed via the file descriptor’”), 2:46–3:7 (“‘the system calls that access files via file descriptors do not distinguish between a file on media and a communication channel’”)); see also PO Resp. 7 (“It is undisputed that file descriptors were conventionally ‘associated with’ files stored on media, communication channels, and even hardware devices.” (emphasis added)). Patent Owner also cites extrinsic evidence, namely, Dunsmuir (Ex. 1007), to support its proposed construction: “Conceptually, a file consists of a stream of data bytes followed by a logical end-of-file. … Because UNIX file I/O is performed through a uniform file interface, a program that can read and write files can read and write anything.” PO Resp. 4 (quoting Ex. 1007, 22). But as noted by Petitioner (Pet. Reply 4–6), Patent Owner does not explain why this “conceptual” meaning set forth in the generic context of programming interfaces in a UNIX operating system would apply in the specific context of the ’613 patent. See Pet. Reply 4 (“[Patent Owner’s] proposed construction is problematic because it is inconsistent with the specification of the ’613 patent.”). Patent Owner also does not explain what “among other common operations” means in the context of its own proposed construction. For the foregoing reasons, and those discussed below, we agree with Petitioner’s proposed construction of “file.” First, the claims of the ’613 patent support Petitioner’s proposed construction. For example, claim 1 recites that a “file” is accessed via a file descriptor. Ex. 1001, 14:55. Claim 5 recites a file descriptor being associated with “a communication channel” and determining with what file type the file descriptor is associated. Ex. 1001, 15:44–57. Together, these limitations show that a “file” is an entity assessed via a file descriptor, and such an entity includes, for example, a communication channel (i.e., per these claims, a communication channel is a type of file associated with a file descriptor). We find nothing in the claims, and Patent Owner does not direct us to anything in the claims, that supports limiting the term “file” only to a “stream of data bytes that can be read and written.”” slip op. at 20

Reply 13 (“Petitioner contended in the Petition and maintains that it is the presence of a file descriptor’s number on the list of monitored file descriptors, not the file descriptor’s number itself, that teaches the claimed indicator.” (bold omitted)); cf.

“In our Institution Decision, we credited the foregoing and related testimony of Dr. Greenspun (Ex. 1002 ¶¶ 96–98), and noted that Patent Owner at that stage of the proceeding had not offered any evidence to rebut Dr. Greenspun’s testimony. Dec. 30–31. Despite that, as highlighted by Petitioner, Patent Owner still offers no evidence to rebut Dr. Greenspun’s testimony in this regard. See Pet. Reply 16 (“But in arguing all these [above arguments], [Petitioner] presents no rebuttal evidence—neither a deposition testimony of Dr. Greenspun, nor a rebuttal testimony by its own expert, nor any other evidence.”); see generally PO Resp. Instead, Patent Owner merely declares Dr. Greenspun’s testimony “conclusory” and tainted by “vague leap[s]” (see, e.g., PO Resp. 14), but yet makes such accusations against a technical declarant with nothing but attorney-argument. Regardless, for the same reasons given by Petitioner (see Pet. Reply 16–18), we disagree with Patent Owner and continue to credit Dr. Greenspun’s technical testimony as to the subject limitation. See Pet. Reply 16–18 (Petitioner explaining why “[Patent Owner’s] attorney argument is wrong”.). As noted above, Patent Owner variously argues Dukach does not disclose “storing” of the indicator at issue in this limitation. See generally PO Resp. 7–17. To summarize, we disagree with Patent Owner, and as explained above, are persuaded by Petitioner’s evidence, including the unrebutted testimony of Dr. Greenspun, that Dukach discloses storing information that points to a file type associated with a file descriptor. First, we are persuaded that, in Dukach, the presence or absence of a file descriptor’s number in the list of monitored file descriptors constitutes information that points to a file type associated with the file descriptor. See Pet. 37–40 (citing, inter alia, Ex. 1005, 11:5–40; Ex. 1002 ¶ 96; Ex. 1001, 11:12–42). Second, we also are persuaded that, in Dukach, the list of monitored file descriptors “needs to be maintained in memory such that it can be used by software to check an at-issue file descriptor’s presence or absence in the list,” which constitutes storing the indicator. Pet. Reply 16– 17 (quoting Ex. 1002 ¶ 97); see Pet. 40 (citing Ex. 1002 ¶ 97). Finally, even if Patent Owner were correct that Dukach does not disclose a particular embodiment in the ’613 patent (see, e.g., PO Resp. 15 (discussing an embodiment “only applicable for binary file types”)), the issue before us is not whether Dukach indeed discloses such an embodiment, but rather whether Dukach discloses the invention recited, for example, in claim 1, given the breadth (scope) of the limitations defining that invention.” slip op. at 37

“2. Burden of Proof To prevail in an instituted derivation proceeding, the petitioner must demonstrate that “an inventor named in the earlier application derived the claimed invention from an inventor named in the petitioner’s application and, without authorization, the earlier application claiming such invention was filed.” 35 U.S.C. § 135(b). Unlike the statutory provisions governing inter partes review and post-grant review, which specify that a petitioner must prove unpatentability of a claim by a “preponderance of the evidence,” the statutory provision for derivation proceedings does not set forth an evidentiary standard for proving derivation. See 35 U.S.C. §§ 135, 316(e), 326(e). Our rules, however, provide that “[a] derivation proceeding is a trial subject to the procedures set forth in subpart A of this part [i.e., 37 C.F.R. §§ 42.1–42.80],” 37 C.F.R. § 42.400(a), and “[t]he default evidentiary standard [for trial proceedings] is a preponderance of the evidence,” 37 C.F.R. § 42.1(d).5 We apply that standard for purposes of this Decision.” slip op. at 17
