“of the invention of the ’613 patent, “would have had a Bachelor’s degree in computer science or a related field, and two years of work experience in operating systems, file systems, networks, and/or client-server applications, though additional education or work experience can make up for more or less formal education.” Pet. 20 (citing Ex. 1002 ¶ 31).

“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

“in the abstract, discloses the claimed “indicator,” but rather the inclusion (or storage or presence) of that number in a list of monitored file descriptors discloses such a stored “indicator.” See, e.g., Pet. 49 (“[The skilled artisan] would have understood that, before the listen( ) call or the accept( ) call attempts to access a file using a file descriptor, it examines the file descriptor to determine if it is on the list of monitored file descriptors—the ‘indicators’ of a file type associated with the control pipe for services to be performed by the front end server.” (emphasis added)); Pet. 37–38 (“Dukach utilizes the presence or absence of a file descriptor’s number stored in a list of monitored file descriptors to indicate the file type associated with the file descriptor, which is how the ’613 patent describes indicating a file type by the indicator’s presence or absence in an indicator table.”); see also Pet. 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. PO Resp. 9 (“[A]n ‘indicator’ . . . must reflect . . . an indication that such file descriptor is associated with a communication channel.”). Patent Owner also variously argues “Dukach does not disclose or” slip op. at 34
- Expert testimonyPetitioner expert creditedDecided for petitioner
“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

Andersen did not prove derivation of any invention in claims 1–22 because it did not show that Oquendo communicated the claimed stop spaced away from the corners.
RulingsFinal written decision- BurdenDecided for patent owner
“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
