DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Information Disclosure Statement
The information disclosure statements (IDS) submitted on 07/24/2025, 08/06/2025, 10/01/2025, and 11/07/2025 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner.
Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.

Allowable Subject Matter
Claims 1-18 are objected to as being rejected on the grounds of non-statutory double patenting, but would be in condition for allowance if the double patenting rejections were to be overcome, such as through the filing of a Terminal Disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d).
The following is a statement of reasons for the indication of allowable subject matter: The prior art does not teach or suggest the combination of limitations presented in the independent claims, with specific regard to inferring that the HRD parameters for all sublayer representations with temporal identifiers (Temporallds) less than a maximum Temporalld are equal to the HRD parameters for a maximum sublayer representation with the maximum Temporalld when the sublayer_cpb params present flag is set to zero, wherein each sublayer representation is a subset of the bitstream containing network abstraction layer (NAL) units of a particular sublayer and lower sublayers, wherein all sublayers are associated with a same number of CPB delivery schedules, and wherein the maximum Temporalld of the maximum sublayer representation is included in the bitstream as a HRD maximum Temporalld (hrd_max_tid[i]] syntax element where i indicates an ith HRD parameter syntax structure.
The closest prior art of reference, Deshpande (U.S. Publication No. 2022/0264153), discloses a bitstream data structure comprising temporal sub-layers with identifiers in the range of 0 to a maximum number of temporal sub-layers minus one, and noting that the reference decoder parameters syntax structure includes parameters for temporal sublayers. However, Deshpande does not expressly disclose the maximum Temporalld of the maximum sublayer representation is included in the bitstream as a hrd_max_tid[i] syntax element, and instead discloses that HighestTid is a calculated variable that is not included in the bitstream.
