    “Petitioner, supported by the testimony of Dr. Reader, argues that a person of ordinary skill in the art (“POSITA”) “would have a bachelor’s degree, or equivalent, in electrical engineering, computer science, a related field, and 2–3 years’ experience researching, designing, or developing content delivery systems and related hardware, software, and firmware, or equivalent experience.” Pet. 14 (citing Ex. 1006 ¶¶ 67–69). Petitioner further argues “[o]ne having less education but more practical experience, or more education and less experience, might also meet this standard.” Id. Patent Owner does not dispute Petitioner’s definition or offer an alternative level or skill in the art. PO Resp. 12 (citing Pet. 14; Ex. 2012). Instead, “[f]or the purposes of this PO Response only, Patent Owner applies Petitioner’s definition of POSITA.” Id. Thus, on this record, the parties agree upon the proposed level of ordinary skill in the art, and this level is consistent with our review and understanding of the technology and descriptions in the ’101 patent and the prior art references that disclose content delivery systems.

    “the gap between the playback deadline and the target schedule, (td(n) − tT(n)), is the target buffer duration, i.e., ‘the desired client buffer duration (in client time).’” Id. at 22–23 (quoting Chou ¶ 74). Petitioner also argues that “in efforts to match upper bound tb(n) to target schedule tT(n), Chou takes into consideration the time duration between target schedule tT(n) and the playback deadline td(n).” Thus, it appears Petitioner assembles three separate and distinct time intervals from Chou’s timing diagrams and equations to construct one contiguous time interval equivalent to claim 1’s remaining time. However, Chou does not recognize the time interval that Petitioner posits, and Petitioner has not persuasively shown that this combined time interval exists as a teaching in the prior art and is used as part of any step or decision involved in determining the code rate. As admitted by Petitioner’s expert, Dr. Reader, Petitioner’s analysis “used the claims as a road map to find limitations in the prior art.” Ex. 2015, 76:4–9 (Reader Deposition Transcript). See also Tr. 28:20–31:2 (Petitioner’s response to whether identification of and integration of separate time ranges described by Chou is hindsight reconstruction, Petitioner argues Chou’s device operates such that code rate is based on remaining time). Under the circumstances, this is improper because Petitioner and Dr. Reader do not justify this combination of separately identified time ranges except based solely on hindsight reconstruction of the claimed invention. However, even if that were not the case, we are not persuaded that Chou or the other asserted prior art references suggest using the combined time interval td(n) − ta(n) as the basis for any decision related to determining the code rate.” slip op. at 37

Furthermore, Petitioner does not address or otherwise dispute Patent Owner’s arguments challenging the asserted obviousness of claims 1, 4–6, 10–16, and 19–26 over the combined teachings of Chou and Wang. Thus, for at least the reasons set forth in our Institution Decision, we agree with Patent Owner that Petitioner fails to show that (1) one skilled in the art would have combined the teachings of Chou and Wang or (2) the combined teaching of Chou and Wang renders limitation 1(d) obvious. e) Conclusion Regarding Claim 1 For the foregoing reasons, we determine that Petitioner has not shown by a preponderance of the evidence that independent claim 1 is unpatentable over the combination of Chou and Wang.” slip op. at 47

    “We find that Holmberg expressly contemplates using its wall box within multi-dwelling units, notes that multi-dwelling wall boxes in the prior art were “typically provided” on every floor, and discloses that the multi-dwelling wall boxes would contain optical couplings for each resident on a given floor. Ex. 1004 ¶¶ 7, 34; Pet. Reply 8–10. In view of these disclosures, we credit the testimony of Dr. Kiaei that one of ordinary skill in the art would have sought to use Holmberg’s wall box in multi-dwelling units and would have seen a need to access the area behind spice tray 230 to connect and disconnect subscribers. Ex. 1003 ¶ 92; Ex. 1033 ¶¶ 7–8. Moreover, even if Holmberg were limited to mid-span locations and distributing drop cables, as opposed to distribution cables for individual subscribers, as asserted by Patent Owner, Patent Owner does not dispute that a technician would still need periodic access to the area behind splice tray 230 in these mid-span devices. Tr. 38:3–39:1 (counsel agreeing that one would need to access the area behind splice tray 230 in Holmberg, albeit in “rare occasions”); Ex. 1003 ¶¶ 90–92; Ex. 1033 ¶¶ 7–8. Thus, whether used in the manner contemplated by Petitioner or Patent Owner, Petitioner persuasively demonstrates that access to the space behind splice tray 230 in Holmberg would be necessary. With access behind splice tray 230 required, Petitioner persuasively demonstrates that one of ordinary skill in the art would have seen a benefit to replacing Holmberg’s fasteners or screws with a hinged connection, such as that disclosed in Battey, to allow easier access to the area behind the splice tray. Pet. 41 (citing Ex. 1005 ¶ 39 (disclosing that a rotatable splice tray or shelf would “provide[] full and convenient access to the splice tray”)). First, Petitioner and Dr. Kiaei persuasively demonstrate that once the fibers of Holmberg are routed from behind splice tray 230 and the distribution cables spooled on this tray, a technician could not reasonably access fiber optic cables stored behind splice tray 230 without releasing or opening splice tray 230. Pet. Reply 14–15 (citing Ex. 1023, 60:20–61:15); Ex. 1033 ¶¶ 31–32. Second, Petitioner persuasively demonstrates that without a hinged connection, the technician would have to either hold the splice tray of Holmberg with one hand while performing the necessary routing and splicing steps, two screws would need to remain in place (essentially replicating a hinge), or the tray would have to be left to dangle, supported only by the routed and spliced fibers.

The Petition asserts that one of ordinary skill in the art would have sought to add a hinged connection, such as that disclosed in Battey, in Holmberg and would have seen a benefit to so doing.

    “For the following reasons, we determine that the portions of the prosecution history of the ’650 patent relied on by Patent Owner do not “prov[e] the existence of a ‘clear and unmistakable’ disclaimer that would have been evident to one skilled in the art.” Trivascular, 812 F.3d at 1063– 64.14 Patent Owner argues that the prosecution history redefined the term forward “by disclaiming workstations that are mounted on top of or over the height adjustment mechanism.” PO Resp. 29. Claims 3 and 4 recite “a work platform including a work surface and compartments for containing items” not a “workstation.” It is unclear what Patent Owner is referring to as the “workstation,” i.e., the recited “work platform,” the recited “work surface,” or the combination of “work platform,” “work surface,” and the recited “compartments.” Patent Owner injects further ambiguity by rephrasing the disclaimer, as “Applicant explicitly disclaimed carts having work stations mounted entirely to the top of the height adjustment mechanism (e.g., carts like Clark and Reeder).” Id. at 30 (emphasis added). Regardless of these 14 Because of our determination that the requirements for a clear and unmistakable disclaimer are not met by the cited portions of the prosecution history of the ’650 patent, we need not and do not reach the question of relevance of the statements in the prosecution of the ’650 patent to the claims of the ’668 patent. ambiguities, Patent Owner misinterprets the statements in the prosecution history. The applicant’s primary argument was that an ordinarily skilled artisan would not have incorporated moveable work surfaces above the “compartment” of Clark. Ex. 1033, 137–38.

    “for use in conjunction with a signal separation unit, in which each received signal has associated channel transfer functions.” Ex. 1001, 12:42–45. The preamble of independent claim 9 similarly recites “a parameter estimation unit for use in conjunction with a signal separation unit for estimating channel transfer function parameters from channel transfer functions.” Id. at 14:4–7. Petitioner, however, contends that “this claim term is not part of the preamble” and that “the preamble is [only] ‘In a multi-user detection system in which interfering signals are purposely allowed to exist.’” Pet. 14. Regardless, Petitioner further contends, to the extent there is any argument that that recitation is part of the preamble, “it is limiting at least because it provides antecedent basis to the ‘parameter estimation unit’ and ‘associated channel transfer functions’ terms that are used in the remainder of the body of the claims and is ‘essential to understanding the structural limitations’ of the parameter estimation unit.” Id. Apart from arguing that the recited “parameter estimation unit” is limiting, Petitioner does not propose any id. Patent Owner does not respond to Petitioner’s contentions and also does not argue that any construction is necessary for the parameter estimation unit. See generally Prelim. Resp. As reproduced in Section II.D. above, the preamble of claim 1, in its entirety, recites, “In a multi-user detection system in which interfering signals are purposely allowed to exist, a parameter estimation unit for use in conjunction with a signal separation unit, in which each received signal has associated channel transfer functions.” Ex. 1001, 12:41–45. The preamble of claim 9 is similar. Id. at 14:3–7 (reciting “In a multi-user detection system in which interfering signals are purposely allowed to exist, a parameter estimation unit for use in conjunction with a signal separation unit for estimating channel transfer function parameters from channel transfer functions”). The body of each claim recites the elements of the recited “parameter estimation unit,” namely, “a signal processor for determining said channel transfer functions for each received signal” and “means . . . for providing uninterrupted estimates of the channel transfer function parameters on a real-time basis . . . .” The phrase “In a multi-user detection system in which interfering signals are purposely allowed to exist” provides additional context for the environment in which the parameter estimation unit is intended to operate. Whether the preamble is limiting is a question that we do not need to decide here, however. Only those claim terms that are in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

    “A claim limitation using the phrase “means for” creates a rebuttable presumption that the drafter intended to invoke 35 U.S.C. § 112 ¶ 6.6 See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015).

When construing a means-plus-function limitation under § 112 ¶ 6, it is necessary first to identify the claimed function, and then to look to the specification to identify the corresponding structure for that function. In re Aoyama, 656 F.3d 1293, 1296–97 (Fed. Cir. 2011); Cardiac Pacemakers, Inc. v. St. Jude Med., Inc., 296 F.3d 1106, 1119 (Fed. Cir. 2002).

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.

    “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

    “(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

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
