“Petitioner’s combination with Cooper, however, does not remedy the deficiencies discussed above with respect to the asserted ground based on Keller-Tuberg alone. See Section II.F. As noted above, Petitioner relies on Cooper’s teaching of a specific delay-reducing algorithm, but continues to rely on Keller-Tuberg for its alleged teaching of “equalizing the difference in latency between the bonded transceivers.” Pet. 53. As Patent Owner argues “dynamically balancing the receive queue lengths to compensate for difference in latency,” as in Petitioner’s combination of Keller-Tuberg and Cooper, “compensates for a difference in configuration latency without doing anything to the actual difference in latency much less ‘utilizing a transmission parameter to reduce a difference in latency.’” Prelim. Resp. 8 compensates for the differences in latency” (emphasis added)). Based on our construction of the “utilizing” term, discussed above (see Section II.C.), we agree with Patent Owner that Petitioner has not shown sufficiently that the combination of Keller-Tuberg and Cooper teaches “reducing a difference in latency between the bonded transceivers” as recited in claim 17. For these reasons, we determine that Petitioner has not demonstrated a reasonable likelihood of prevailing on its assertion that claim 17, or claim 18 which depends therefrom, would have been obvious in view of Keller- Tuberg and Cooper.” slip op. at 30

“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 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

“added). Dr. Houh testifies that an ordinarily skilled artisan would have used Wiser’s voucher ID in Eyal’s play-list because delivery servers may have a “limited number of active streams of data being delivered at any one time,” so that generating and tracking reservations by the content server using voucher IDs is necessary. Ex. 1003 ¶ 144 (citing Ex. 1006, 14:65−15:1). We agree with and credit Dr. Houh’s testimony, and we find that such an artisan of ordinary skill would have understood that, in Eyal in combination with Wiser, the voucher ID provided in the play-list is uniquely associated with the client device and a viewing session of the media. Ex. 1003 ¶ 151 (citing Ex. 1006, 8:30−33, 15:23−28). We do not agree with Patent Owner’s assertion that “Wiser teaches away from video.” PO Resp. 33 (citing Ex. 2012 ¶ 174). “A reference may be said to teach away when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). Here, nothing in Wiser would discourage a relevant artisan from applying its teachings to video media, as Patent Owner alleges. Patent Owner’s argument of teaching away is based on speculation. As discussed above, Wiser’s disclosure is not limited to audio media. Ex. 1006, 1:5−8, 1:23−26, 3:8−10; Ex. 1083, 145:20−147:21. The “mere disclosure of alternative designs does not teach away.” In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Moreover, KSR instructs us that “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize 20 that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417.

We rely, instead, on Dr. Houh’s testimony, summarized above, that there would be advantages in combining the teachings of Eyal and ASF Files. Houh Decl. ¶¶ 140–141.

See Ex. 1017, 1 (“ASX files are simply text files that act as links from Web pages to ASF files on Windows Media Services or HTTP servers.”).

One of those required elements of the claimed play script is “one or more instructions for use by the communication device together with the at least one URL to cause the at least one portion of the requested media to be streamed to the communication device.” See claim element 1.c.4, Ex. 1001, 51:8–11. We find that there is inadequate written description in the ’519 application of “instructions . . . to enable the communication device to obtain the at least one portion of the requested media.” Reply 8–9. We agree with Petitioner that the “presentation identification” relied on by Patent Owner (Ex. 2015, 7) does not provide “instructions…to enable the communication device to obtain the at least one portion of the requested media.” Reply 13. Instead, the “presentation identification” “identifies a particular presentation . . . and its associated media.” Id. (quoting PO Resp. 36). Absent an adequate written description in the ’519 application of these claimed features, Patent Owner’s attempt to obtain the benefit of the filing date of that application for the challenged claims of the ’635 patent fails. “It is elementary patent law that patent claims are entitled to the benefit of the filing date of an earlier filed application only if the disclosure of the earlier application provides support for the claims of the later application, as required by 35 U.S.C. § 112.” PowerOasis, Inc. v.

“’887 patent makes clear that the presentation itself, not the presentation ID, “may include special instructions, such as special media sequencing instructions, late binding media instructions, and/or special routing instructions.” Ex. 1001, 8:27–32. Therefore, Patent Owner’s argument that the presentation ID is an instruction executed by the communication device “to obtain at least one portion of the requested media,” as required by the claims, is not supported by the ’993 application, the ’519 application, or the draft application, and it is also inconsistent with the Specification of the ’887 patent.

“We agree with Petitioner. Patent Owner’s implicit claim construction improperly imports extraneous limitations into the claims—namely, excluding the entirety of the “requested media” or requiring that the “requested media” be broken up into portions. It is well-settled that if a feature is not necessary to give meaning to what the inventor means by a claim term, it would be “extraneous” and should not be read into the claim. Renishaw PLC v. Marposs Societa’ per Azioni, 158 F.3d 1243, 1249 (Fed. Cir. 1998); E.I. du Pont de Nemours & Co. v. Phillips Petroleum Co., 849 F.2d 1430, 1433 (Fed. Cir. 1988). The plain and ordinary meaning of the term “at least one portion of the requested media” as used in the ’887 patent does not support Patent Owner’s implicit construction. In the context of the ’887 patent, the plain 4 For example, other variations include “at least a portion of the requested media” recited in claim 1 and “the at least the portion of the requested media” recited in claim 2. 10 and ordinary meaning of the term encompasses one or more portions of the “requested media,” as well as the entirety of the “requested media.” For example, the portions of the Specification relied upon by Patent Owner disclose that the viewer requests a media clip and receives the entirety of the requested media clip, not one portion at a time.

“Upon review of this entire trial record, we are persuaded by Petitioner’s showing and find that the challenged claims recite a concept that falls within one of the enumerated groupings of abstract ideas—certain methods of organizing human activity, e.g., “commercial or legal interactions (including agreements in the form of contracts; legal obligations; advertising, marketing or sales activities or behaviors; business relations).” See Guidance, 84 Fed. Reg. at 52. The abstract idea here is not meaningfully different from the ideas found to be abstract in other cases before the Federal Circuit. Notably, each challenged claim recites a method in which a “computing device” generates a “communication” based on the characteristics of the user in response to a request for media to be streamed. The Federal Circuit has held that “the concept of delivering user-selected media content to portable devices is an abstract idea.” Affinity Labs of Texas, LLC v. Amazon.com Inc., 838 F.3d 1266, 1269 (Fed. Cir. 2016). The Federal Circuit also has held that claims related to “customizing information based on (1) information known about the user and (2) [specific] data” are directed to abstract ideas. Intellectual Ventures I LLC v. Capital One Bank (USA), 792 F.3d 1363, 1369−70 (Fed. Cir. 2015) (noting that “[a]n advertisement taking into account the time of day and tailoring the information presented to the user based on that information is another ‘fundamental . . . practice long prevalent in our system’” (quoting Alice, 573 U.S. 219)); see also British Telecommunications PLC v. IAC/InterActiveCorp, 813 F. App’x 584, 587 (Fed. Cir. 2020) (holding that the concept of “providing lists of 30 location-specific information sources to users based on their location” was an abstract idea). In addition, we find that the claim limitations involving a “revenue sharing rule” and “producing a settlement record” that reflects the revenue sharing do not remove the challenged claims from the realm of abstract ideas. See, e.g., Pet. 38−40. Notably, recording revenue sharing constitutes a practice of organizing human activity, which is rooted in assessing sales and economic interactions—a fundamental economic practice. The Supreme Court has held in Alice that “a method of exchanging financial obligations between two parties using a third-party intermediary to mitigate settlement risk” is “a fundamental economic practice long prevalent in our system of commerce” and that “the concept of intermediated settlement . . . [is] squarely within the realm of ‘abstract ideas.’” Alice, 573 U.S. at 219−22.” slip op. at 30
