SAADAT, JUSTIN BUSCH, and JAMES W. DEJMEK, Administrative Patent Judges. BUSCH, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Pursuant to 35 U.S.C. § 134(a), Appellant1 appeals from the Examiner’s decision to reject claims 1–6, 8–15, 17–25, 27–34, and 36–38. We have jurisdiction under 35 U.S.C. § 6(b). We reverse. 1 We use the term Appellant to refer to “applicant” as defined in 37 C.F.R. § 1.42(a) (2018). Appellant identifies the real party in interest as InterDigital Madison Patent Holdings. Appeal Br. 3. Appeal 2019-004355 Application 14/913,399 2 CLAIMED SUBJECT MATTER The claimed subject matter relates to a low adjacent channel interference mode for a digital television system and, in particular, for a multi-carrier modulation system, such as OFDM, that is replacing and temporarily co-existing with an existing standard. Spec. ¶ 5. More specifically, the claimed subject matter includes allocating non-signaling data to carriers according to a bandwidth parameter, which identifies a bandwidth operation mode (e.g., normal, reduced, or extended), sending the parameter in a preamble to a receiver, and the receiver extracting the parameter to set the operation mode to appropriate demodulate the rest of the signal. Spec. ¶¶ 22–24. Claim 1, reproduced below, is illustrative of the claimed subject matter: 1. An apparatus for transmitting a multi-carrier modulated signal comprising: a source that provides data, said data comprising a bandwidth parameter, said bandwidth parameter comprising a normal bandwidth mode, at least one reduced bandwidth mode and at least one extended bandwidth mode; and a multi-carrier modulator that modulates said data by allocating said data to a plurality of carriers within one physical channel according to said bandwidth parameter to create said modulated signal, wherein each bandwidth mode determines a number of carriers within the one physical channel, wherein the at least one reduced bandwidth mode has a smaller number of carriers than the normal bandwidth mode and the at least one extended bandwidth mode and wherein the at least one reduced bandwidth mode is used for reducing adjacent channel interference on at least one adjacent channel to said physical channel carrying said multi-carrier signal.

Final Act. 10–25. Claims 3, 12, 22, and 31 stand rejected under 35 U.S.C. § 103 as being obvious over La Joie, McFarland, Sudo, and Leung. Final Act. 25–29. Claims 5, 14, 24, and 33 stand rejected under 35 U.S.C. § 103 as being obvious over La Joie, McFarland, Sudo, and Linden. Final Act. 30– 33. Claims 4, 6, 13, 15, 23, 25, 32, and 34 stand rejected under 35 U.S.C. § 103 as being obvious over La Joie, McFarland, Sudo, and Scipione. Final Act. 33–39. Claims 8, 9, 17, 18, 27, 28, 36, and 37 stand rejected under 35 U.S.C. § 103 as being obvious over La Joie, McFarland, Sudo, and Chen. Final Act. 40–41. ANALYSIS The Examiner finds the combination of La Joie, McFarland, and Sudo teaches or suggests every limitation recited in independent claims 1, 10, 20, Appeal 2019-004355 Application 14/913,399 4 and 29. Final Act. 10–23. Of particular relevance to this Appeal, the Examiner finds La Joie teaches or suggests both “a bandwidth parameter” and the disputed modulating step—“a multi-carrier modulator that modulates said data [comprising a bandwidth parameter] . . . to create said modulated signal” (the “disputed limitation”), as recited in independent claim 1 and commensurately recited in independent claims 10 (“a multi- carrier demodulator that demodulates said modulated signal” and “a signaling data detector that detects signaling data from demodulated signaling data symbols and that recovers said bandwidth parameter”), 20 (“multi-carrier modulating said data [comprising a bandwidth parameter] . . . to create said modulated signal”), and 29 (“multi-carrier demodulating said modulated signal” and “detecting signaling data from demodulated signaling data symbols and for [sic] recovering said bandwidth parameter”). Final Act. 10–12 (citing La Joie ¶¶ 70, 75, 88, 134, 155, Figs. 1a–1b), 17–19 (citing La Joie ¶¶ 65, 70, 87, 102, 109, 111, 131, 136, Fig. 6). More specifically, the Examiner finds La Joie teaches a bandwidth parameter because La Joie teaches scheduling and transmitting content have various service levels, such as standard definition (SD), high definition (HD), and ultra-high definition (UHD). Final Act. 10 (citing La Joie ¶ 70). The Examiner finds La Joie teaches or suggests the modulating step because La Joie’s modulator 162 modulates a signal, La Joie maps program channels to corresponding physical channels, and La Joie discloses distributing content having certain service levels on a certain physical channels. Final Act. 11 (citing La Joie ¶¶ 88, 134, 155, Figs. 1a–b). Among other arguments, Appellant asserts La Joie does not teach or suggest the modulating step because La Joie does not modulate data that includes its service levels, which the Examiner finds teach the bandwidth Appeal 2019-004355 Application 14/913,399 5 parameter, as recited in the disputed limitation. Appeal Br. 9 (“Applicants’ claim 1 requires that the modulated data comprise a bandwidth parameter.”). More specifically, Appellant asserts that, to the extent La Joie’s service levels (e.g., standard definition (SD), high definition (HD), and ultra-high definition (UHD)) teach a bandwidth parameter, “there is no description, or suggestion, in La Joie, of a bandwidth parameter that is in the data as required.” Appeal Br. 9. The Examiner responds to Appellant’s argument by finding that the claims do not recite the particular structure or format of the bandwidth parameter, requiring only that the data comprises the bandwidth parameter. Ans. 35. The Examiner finds the parameter, therefore, may be in any form, including La Joie’s disclosed “service levels of SD, HD, [and] UHD” (ultra- high definition). Ans. 35. The Examiner also finds the distributed content has various properties (e.g., format, resolution, frame size, and file size) that “would provide the associated bandwidth parameter.” Ans. 35. The Examiner concludes that “La Joie’s service mode and/or properties pertaining to the content itself under broad[e]st reasonable interpretation meets Appellant[’]s claimed limitation where ‘data comprising a bandwidth parameter.’” Ans. 35–36. We agree with the Examiner that the claim does not require a particular form for the bandwidth parameter and that, to the extent La Joie suggests parameters indicating the different service levels, such parameters may teach a bandwidth parameter. We disagree, however, that merely the fact that distributed content has certain properties, such as a service level, teaches or suggests including such properties as a parameter, let alone a bandwidth parameter, in the modulated data, as recited in Appellant’s claims. Appeal 2019-004355 Application 14/913,399 6 Even assuming that La Joie stores the service level as a parameter for some purpose (e.g., to construct the mapping information), we see nothing in the Examiner’s findings or La Joie’s cited disclosures that teaches or suggests transmitting the service level (or any other content property). Accordingly, the record does not support a finding that La Joie modulates data that includes La Joie’s service level to create a modulated signal. Furthermore, the mapping information, which the CPE uses to tune its tuner to a physical channel, associates program channels with physical channels on which programming content will be transmitted, but there is no suggestion that the mapping information includes the service levels. La Joie ¶¶ 85–89. Accordingly, we see nothing in the Examiner’s findings or La Joie’s cited disclosures that teaches or suggests that the mapping information or the content, which are modulated and sent to the customer premises equipment (CPE), include La Joie’s service levels (or any other property that may teach a bandwidth parameter). CONCLUSION For the above reasons, on this record, we do not sustain the rejection of independent claims 1, 10, 20, and 29, which recite the disputed modulating step, under 35 U.S.C. § 103 as obvious over La Joie, McFarland, and Sudo. Nor do we sustain the rejection of claims 2, 11, 19, 21, 30, and 38, which depend therefrom and incorporate the disputed modulating step, under 35 U.S.C. § 103 as obvious over La Joie, McFarland, and Sudo. The Examiner does not find any one of Leung, Linden, Scipione, and Chen cures this deficiency. Therefore we do not sustain the rejections of claims 3–6, 8, 9, 12–15, 17, 18, 22–25, 27, 28, 31–34, 36, and 37, which depend from one of claims 1, 10, 20, and 29, thereby incorporating the disputed modulating Appeal 2019-004355 Application 14/913,399 7 step, under 35 U.S.C. § 103 as obvious over La Joie, McFarland, and Sudo in combination with one of Leung, Linden, Scipione, and Chen. Because we do not sustain the rejection for the above reasons, we need not address Appellant’s other arguments.
