Where a Petition presents a reasonable likelihood of success as to only a small number of the challenged claims, the Board has the discretion to decline to institute review, because instituting a full review on all challenged claims may be an inefficient use of the Board’s limited resources. See, e.g., Deeper, UAB v. Vexilar, Inc., IPR2018-01310, Paper 7 at 42–43 (PTAB Jan. 24, 2019) (informative) (denying institution where a petitioner demonstrated a reasonable likelihood of success on only two out of twenty- a petitioner demonstrated a reasonable likelihood of success on only two out of twenty claims). Of the eighteen challenged claims, we have found that Petitioner failed to establish a reasonable likelihood of success as to sixteen of those claims. This leaves a single independent claim (claim 17) and a single dependent claim (claim 18) remaining for consideration. Even were we to conclude that Petitioner had established a reasonable likelihood of success as to claims 17 and 18, this would leave at most two claims subject to a single ground upon which such a showing had been made, out of eighteen challenged claims. Based on the particular circumstances of this case, it would be inefficient for the Board to expend resources on a full review of all eighteen challenged claims, where Petitioner has failed to establish even a reasonable likelihood of success as to the vast majority of those claims. Accordingly, we need not, and do not, take any position as to Petitioner’s showing on Ground 2 but instead exercise our discretion to deny review.” slip op. at 21

“Following the block quote from Yacenda, the applicant then stated, “[b]ased on the foregoing, Yacenda’s system is directly opposite of the instant claims, as the instant claims require a ‘pre-printed lottery ticket’ which has no lottery numbers associated with it at the time of customer purchase.’” Ex. 1002, 76. This statement is clear and unmistakable. It (1) specifically states that “the instant claims require” and (2) then states what the claims require—a “‘pre-printed lottery ticket’ which has no lottery numbers associated with it at the time of customer purchase.” We fail to see how the applicant could have been more clear in stating a requirement of the Challenged Claims. And, by doing so, the applicant narrowed the scope of what would otherwise be encompassed in the meaning of “pre-printed lottery ticket” and therefore what would otherwise be encompassed in the scope of the Challenged Claims—a lottery ticket which has lottery numbers associated with it at the time of customer purchase.” slip op. at 27
- Expert testimonyPetitioner expert discountedDecided for patent owner
“We do not find Mr. Hutton’s testimony particularly helpful. First, we have addressed the points raised by his testimony in our discussion above because they are largely the same as the arguments raised in Petitioner’s Reply. Second, we find his testimony entitled to very little weight because he applies an incorrect understanding of the caselaw, which mirrors Petitioner’s incorrect and arguably misleading quotations of the Federal Circuit’s decision in Quest. In particular, in paragraph 5, Mr. Hutton states the following as his understanding of the law as it applies to prosecution disclaimer: “I also understand that in order to disclaim embodiments within the specification, the statements should have some indication that the applicant intended to surrender embodiments from the specification.” Ex. 1038 ¶ 5 (emphasis added). This then leads Mr. Hutton to state: “[t]hus, in my opinion, a [person of ordinary skill in the art] would not view applicant’s statements as a disclaimer, because the applicant never stated that they intended to surrender multiple embodiments described in the specification.” Id. ¶ 13 (emphasis added). As we explained above in responding to a similar argument by Petitioner, the caselaw does not require an applicant to expressly state whether a disclaimer excludes particular embodiments of the subject specification when disclaiming claim scope during prosecution. See Quest, 924 F.3d at 1229. And, as noted above, counsel for Petitioner agreed that such a statement explicitly disclaiming particular embodiments is not required. Tr. 12:18–13:17. Third, although we have considered Mr. Hutton’s testimony, we find it “less significant than the intrinsic record in determining the legally operative meaning of” “pre-printed lottery ticket.” Phillips, 415 F.3d at 1317. In particular, we are cognizant of the Federal Circuit’s guidance that we “should discount any expert testimony that is clearly at odds with the claim construction mandated by . . . the prosecution history.” Id. at 1318 (internal quotation omitted). In this instance, for the reasons explained above, we find that Mr. Hutton’s testimony is clearly at odds with the applicant’s arguments during prosecution and that his testimony is based on a misunderstanding of what is required by the governing caselaw for prosecution history disclaimer.” slip op. at 43

Although Mr. Taniguchi doubtlessly spent substantial time preparing the application he completed on November 6, 2008 (see Ex. 2017), there is no corroborating evidence that this work was reasonably continuous during the critical period. As far as the corroborating evidence attests, Mr. Taniguchi could have done no work on the draft until early November, or he could have worked on the draft briefly in August and put it aside until early November. Considering all the evidence as to Mr. Taniguchi’s activities, we find that Patent Owner has not met its burden of producing corroborating evidence that the named inventors of the ’427 patent exercised reasonably continuous diligence during the critical period when Ueda was filed until the constructive reduction to practice that occurred on November 18, 2008.

“(4) Whether Ueda Teaches Away from Providing Play-list Information While Establishing a Connection Finally, Patent Owner argues that Ueda teaches away from providing “play-list information” at the same time as establishing a connection, because Ueda teaches successfully completing user authentication before transmitting the playlist. PO Resp. 52–53 (citing Ex. 1003 ¶¶ 56, 365, Fig. 25; Ex. 2001 ¶ 99). According to Patent Owner, “Petitioner’s argument fails to reconcile[] this ordering of Ueda, which would prevent implementation of the proposed combination with the SDP Standard, in which the playlist is transmitted as part of the ‘Session Initiation.’” Id. at 53 (citing Ex. 2001 ¶ 100). In its Reply, Petitioner argues that limitation 1g “does not require transmitting ‘play-list information’ ‘at the same time’ as authentication, but at a same time ‘the one or more connection control servers executes a process for guaranteeing a communication bandwidth . . . as a process for establishing the connection.’” Pet. Reply 23. Petitioner also argues that the ’427 patent also describes an authentication step before transmitting the play-list information. Id. (citing Ex. 1001, 12:56–13:13, 13:50–58, Fig. 4). We find Petitioner’s arguments persuasive, and we disagree with Patent Owner that claim 1 restricts the timing of user authentication. As Petitioner notes, user authentication occurs in the ’427 patent before the process of establishing a connection as depicted in Figure 5. See Ex. 1001, 12:36–55, Fig. 4 (user authentication occurs when user equipment 2 is powered-up); id. at 13:50–58 (SIP message A501, at the beginning of Figure 5, includes “user authentication success information”). But we find nothing in the claim language, itself, that requires any particular timing for authentication. Nor do we understand Petitioner’s motivation-to-combine argument to hinge on the timing of authentication. Thus, Ueda does not “criticize, discredit, or otherwise discourage” the claimed invention.

- Obviousness (§103) › Motivation to combine / reasonable expectation of success › HindsightDecided for petitioner
“We find Petitioner’s arguments persuasive. Petitioner does not rely solely on the SDP Standard for teaching the sending of play-list information, but also relies on Ueda, which discloses sending a playlist including an identification of main content, commercial content, and an output sequence, as we discuss in more detail below in the context of limitation 1h. See infra Section III.D.3(g). Petitioner relies on the SIP and SDP Standards for teaching that Ueda’s playlist, as with other data describing a session, may be formatted and transmitted as payload within a standard SIP message, for example using SDP fields. Based on the evidence of record, we find it persuasive that a person of ordinary skill in the art would have recognized SDP as a known way to format play-list information, since SDP has specific fields to convey the features of a playlist such as metadata and links to the content. See Pet. 50–52. Petitioner’s arguments are not based on improper hindsight bias. Although Petitioner argues that the SDP Standard “can” or “could” be used to format Ueda’s playlist, the evidence suggests that doing so would merely be “[t]he combination of familiar elements according to known methods,” and that kind of combination “is likely to be obvious when it does no more than yield predictable results.” KSR, 550 U.S. at 416. The evidence shows that is the case here. As such, the Petition relies on the predictable combination of the prior art according to known methods and on various motivations to combine the references (see Supra Sections III.D.1–2), not on the ’427 patent itself, for teaching the combination.” slip op. at 57

Prelim. Resp. 26. We are not persuaded by this assertion. First, Ericsson is not a precedential or informative decision and is not binding on us or informative to our analysis. Moreover, in that case there were five prior petitions that covered all of the challenged claims, and the petitioner admitted crafting its petition based on its review of the prior petitions. Ericsson at 3, 11. Petitioner here has not made such a concession, and moreover, Patent Owner has not presented any evidence that Petitioner actually did use the petition in IPR2024-00506 as a roadmap. Under the circumstances, we find no evidence that Petitioner used the prior petition filed by Cisco as a roadmap, particularly when none of the timing associated with the prior petition was within its control. We find no significant relationship between Petitioner and Cisco. “[W]here, as here, the first and second petitioners are neither the same party, nor possess a significant relationship under Valve, General Plastic factor one necessarily outweighs the other General Plastic factors.” Videndum Prod.

“sufficient showing that a POSITA would have been motivated to apply Hu’s concept of aggregating ports to form a high-capacity port for transmitting multicast streams to the network device disclosed by Blease, and we do not agree that Blease teaches away from incorporating such aggregation. Both Blease and Hu are directed to similar subject matter, processing multicast stream requests, and Hu’s link aggregation addresses the problem of potentially overloading a port when doing so. See, e.g., Ex. 1005, code (57) (“The network device transmits multicast traffic to the subscriber devices.”); Ex. 1007, claim 17 (“A network device to allocate media streams . . . .”), 1:20–29 (disclosing that, if “insufficient bandwidth [is allocated] to video streams, the quality of service degrades”); see Intel Corp. v.

On this record, we are persuaded that applying Hu’s port aggregation teaching to Blease’s router would be the application of a known technique to improve the router to allow it to provide multicast streams that require higher bandwidth with predicable results. Pet. 28; see KSR, 550 U.S. at 415–21. As pointed out by Petitioner, these two concepts could be combined together in a straightforward manner and applied to streams that require high-capacity ports, a technique already applied elsewhere in Blease to other ports, so a POSITA would have had a reasonable expectation of success in doing so. Pet. 28–29; Ex. 1003 ¶¶ 93–94; see Elekta Ltd. v. Zap Surgical Sys., Inc., 81 F.4th 1368, 1377 (Fed.

Philip Morris Inc., 229 F.3d 1120, 1125 (Fed. Cir. 2000)). On this record, we are unpersuaded by Patent Owner’s argument that Blease teaches away from using aggregated ports to form a high-capacity link because “Blease’s disclosure is clear that the focus of its multicast techniques is to reduce, not increase, the amount of multicast traffic flowing through network.” Prelim. Resp. 14. The discussion in Blease of minimizing the bandwidth does not relate to restricting the bandwidth required for a particular stream as Patent Owner seems to assert, but rather to eliminating duplicate transmissions of the same multicast stream to be delivered to multiple subscribers. See Ex. 1005, 2:39–42, 4:50–56 (“The multicast transmission techniques described herein may significantly reduce the amount of multicast traffic . . . . For example, regardless of the number of subscriber devices[] connected to the same network switch that request the same multicast stream, [the] network device[] only sends one copy of the multicast stream to the network switch.”). Therefore, aggregating ports to accommodate transmission of a single multicast stream that requires more bandwidth is a different concept that is unrelated to the discussion in Blease about minimizing bandwidth by increasing efficiency.” slip op. at 37
