Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 7-8, 10, 13, 20 and 25 is/are rejected under 35 U.S.C. 103 as being unpatentable over Aksu et al, in view of Wang et al (US 20250193457).
Regarding claim 7, Aksu et al teaches parameters describing the post-filter characteristics. The reference is unclear with respect to information indicating the purpose of the post-processing filter.
In similar field of endeavor, Wang et al teaches information indicating the purpose of the post-processing filter (Para. 0037; Table 20). Therefore, it would have been obvious to one of ordinary skill in the art to modify the reference before the effectively fling date of the claimed invention for the common knowledge purpose to give reconstructed data unit a concrete, decodable structure.
Regarding claim 8, Aksu et al teaches parameters describing the post-filter characteristics. The reference is unclear with respect to information indicating the complexity of the post-processing filter.
In similar field of endeavor, Wang et al teaches information indicating the complexity of the post-processing filter (Para. 0030; 8.28). Therefore, it would have been obvious to one of ordinary skill in the art to modify the reference before the effectively fling date of the claimed invention for the purpose to give reconstructed data unit a concrete, decodable structure in addition to whether device can process information.
Regarding claim 10, Aksu et al teaches parameters describing the post-filter characteristics. The reference is unclear with respect to information indicating a base or an update.
In similar field of endeavor, Wang et al teaches information indicating a base or an update (Para. 0036). Therefore, it would have been obvious to one of ordinary skill in the art to modify the reference before the effectively fling date of the claimed invention for the purpose to give reconstructed data unit a concrete, decodable structure.
Regarding claims 13, 20 and 25, Aksu et al teaches limitations discussed with respect to claims 1, 3 and 23. The reference is unclear with respect to the post-filter data unit is a neural-network post-filter characteristics, NNPFC, SEI message.
In similar field of endeavor, Wang et al teaches the post-filter data unit is a neural-network post-filter characteristics, NNPFC, SEI message (Figure 4; Abstract). Therefore, it would have been obvious to one of ordinary skill in the art to modify the reference before the effectively fling date of the claimed invention for the purpose to give reconstructed data unit a concrete, decodable structure.
