“In sum, we find that Petitioner’s arguments, and Dr. Fuja’s cited testimony, are not compelling. Accordingly, Petitioner’s showing as to independent claim 14 is less than a “compelling, meritorious challenge[].” In addition, claims 15–19 depend from claim 14, and Petitioner’s arguments for these dependent claims do not cure the above deficiencies for independent claim 14. Pet. 26– 31. Likewise, Petitioner’s arguments for dependent claims 15 and 18 for the remaining ground (Kotecha combined with R1-081126) do not cure the above deficiencies for independent claim 14. Pet. 31–34. Thus, Petitioner’s showing of unpatentability is not compelling for any of the challenged claims for any of the asserted grounds. VII. CONCLUSION For the foregoing reasons, we exercise our discretion to deny the Petition. VIII.

“We find that Petitioner’s arguments are not compelling. First, we have doubts as to whether Kotecha (i) teaches a scheme “which utilizes a CQI trigger, a particular MCS value, and other fields present in the uplink grant” or (ii) “encourages [one of ordinary skill in the art] to use fields in addition to the MCS field.” Pet. 23–24. Rather, it appears that Kotecha teaches in its discussion regarding using a CQI trigger and a particular MCS value that “different fields, other than the MCS field, may be reused according to [Kotecha’s] disclosure to clearly signal whether an uplink grant is for only CQI or CQI and data.” See Ex. 1004, 4:23–43 (emphasis added). Hence, Kotecha teaches using other fields in lieu of—not in addition to—the MCS field. Id. Moreover, Kotecha’s teachings regarding using “one or more fields” to indicate only CQI or CQI and data identify the CQI request and MCS fields, as examples, without identifying additional fields, nor requiring the use of these fields. See id. at 7:19–22, 8:15–20, Fig. 6. Thus, these teachings also do not provide compelling support for Petitioner’s arguments that Kotecha encourages adding a third field to the CQI request and MCS fields combination. Id. Second, we find uncompelling Petitioner’s argument that one of ordinary skill in the art “would have been motivated to try using the . . . (RB) assignment field as a further indication of whether to multiplex CQI with data,” which “is one of only seven other possible fields for [one of ordinary skill in the art] to consider.” Pet. 25. This argument is premised on Kotecha encouraging using a third field—and only a third field—in addition to the CQI request and MCS fields, which, as we discuss above, Kotecha does not. Rather, choosing any three, for example, of the nine fields in the uplink grant would yield 84 possible combinations. See Ex. 1004, 1:25–34 (listing nine fields); Ex. 1003 ¶ 78 (testifying that “Kotecha identifies nine fields in the uplink grant”). Yet more combinations are possible if combinations having other numbers of fields are employed. “[T]he breadth of these choices and the numerous combinations indicate that these disclosures would not have rendered the claimed invention obvious to try.” Leo Pharm. Prod., Ltd. v. Rea, 726 F.3d 1346, 1356 (Fed. Cir. 2013) (citing Rolls–Royce PLC v. United Techs. Corp., 603 F.3d 1325, 1339 (Fed. Cir. 2010)). Nor does Petitioner cite to any guidance provided in Kotecha about which combinations of fields would likely be successful in arguing that the claimed three field combination would have been obvious to try. See In re Kubin, 561 F.3d 1351, 1359 (Fed. Cir. 2009) (“[W]here a defendant merely throws metaphorical darts at a board filled with combinatorial prior art possibilities, courts should not succumb to hindsight claims of obviousness.”).” slip op. at 22

“Third, we do not find compelling Dr. Fuja’s cited testimony, which in our view, and taken as a whole, risks using impermissible hindsight to reconstruct the invention of claim 14. See Metalcraft of Mayville, Inc. v. The Toro Co., 848 F.3d 1358, 1367 (Fed. Cir. 2017) (“[W]e cannot allow hindsight bias to be the thread that stitches together prior art patches into something that is the claimed invention.”); In re Fritch, 972 F.2d 1260, 1266 (Fed. Cir. 1992) (“It is impermissible to use the claimed invention as an instruction manual or ‘template’ to piece together the teachings of the prior art so that the claimed invention is rendered obvious.” (citation omitted)). For example, the testimony appears to be predicated incorrectly on Kotecha teaching using a third field (i.e., the resource assignment field) in addition to the CQI request and MCS fields, and the testimony instead tracks the claimed three field combination of claim 14. Ex. 1003 ¶¶ 77–79. Moreover, Dr. Fuja opines that “it would have been obvious for [one of ordinary skill in the art] to use the resource assignment field in the uplink grant in addition to the CQI request bit and the MCS field because doing so provides additional flexibility and greater efficiency at no additional cost.” Ex. 1003 ¶ 79. We find this testimony to be conclusory as there is no factual support underlying Dr. Fuja’s opinion that one of ordinary skill in the art would have found such to be obvious. Id. ¶¶ 77–83. Also, claim 14 recites more than just reusing the resource assignment field to indicate whether data should be multiplexed with the CQI report. Ex. 1001, 24:7–14. Rather, claim 14 also recites evaluating whether the indicated number of resource blocks “is smaller than or equal to a determined number of resource blocks.” Id. Kotecha does not teach this, nor does Dr. Fuja address it in a compelling way. See Ex. 1003 ¶¶ 77–83.” slip op. at 23

“implemented by a base station. As Petitioner points out, Classon describes a multicarrier communications system that includes a “base site” and “receiving platforms” (also referred to as “transmission targets”), which we find are a base station and mobile stations. Pet. 19–20 (citing Ex. 1005, code (57), ¶¶ 23, 27, 28, 31, Fig. 4). The parties dispute whether Classon (in light of the background knowledge of a skilled artisan or, in light of TR 25.858) teaches transmitting control information indicating whether a mobile station is to transmit one channel quality indicator (CQI) for each subcarrier block within a communication frequency band or one CQI for all subcarrier blocks within the communication frequency band instead of multiple CQIs for multiple subcarrier blocks within the communication frequency band, as recited in claim 1 (and similarly recited in claim 11). For the reasons given below, the case Petitioner advances is less than compelling.” slip op. at 21

“Patent Owner’s argument has merit. Paragraphs 37–40 of Classon describe the base station determining what mode to use for communication based on the information (including CQI information) sent by the mobile units. Paragraph 41 states that “such channel quality information will preferably already be available to the base site” but that, if it is not available, “the base site can transmit 73 a message to the relevant transmission target or targets and request a reply that includes the relevant channel quality information.” Also, paragraph 41 states that “[w]ays in which such information can be provided to the base site will be described below in more detail.” This appears to be a reference to Classon’s description of the mobile stations, not the base station, determining that they are of “type 1” or “type 2” and sending channel quality information to the base station based on that determination, after which the base station determines whether to use the first mode or second mode in communications. Ex. 1005 ¶¶ 45–51. Thus, rather than supporting Petitioner’s position, the context around paragraph 41 appears in friction with that position. Petitioner does not explain how the base station determines a transmission mode (and thus a requested amount of CQI information) without first having that information from the mobile stations. Instead, it is reasonable to read paragraph 41 as requesting of the mobile stations information that the mobile stations deem appropriate; in other words, that the mobile stations determine whether to send a CQI value for each subcarrier or information on average channel quality. Even if it is sufficient to go forward on a theory that Classon implicitly teaches the claimed control message, the evidence Petitioner advances for this position is not compelling.” slip op. at 23
