Office Action

§103
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 . Response to Arguments Applicant’s arguments with respect to claim(s) 1 and 2 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1 and 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chujoh et al. (Chujoh) (US 2023/0421785) in view of Esenlik et al. (Esenlik) (US 2023/0336784). Regarding claims 1 and 2, Chujoh discloses a device comprising one or more processors configured to: receive a neural network post-filter characteristics supplemental enhancement information (SEI) message (FIG. 9, [0143], [0158], a post-filter characteristic SEI signal is received; [0014], a neural network is used for processing); parse a first syntax element in the neural network post-filter characteristics SEI message, wherein the first syntax indicates overlapping horizontal and vertical sample counts of adjacent input tensors ([0190], a syntax element nnpfc_overlap indicates the number of horizontal pixels and the number of vertical pixels for which neighboring input tensors are overlapped. The value of nnpfc_overlap is a value from 0 to 16383) of a neural network post-filter corresponding to the neural network post-filter characteristics SEI message (FIG. 9, [0143], [0158], [0159], a post-filter characteristic SEI signal is received) and the first syntax element is in a range of 0 to 16,383, inclusive ([0190], a syntax element nnpfc_overlap indicates the number of horizontal pixels and the number of vertical pixels for which neighboring input tensors are overlapped. The value of nnpfc_overlap is a value from 0 to 16383); derive an input tensor for the neural network post-filter based on the indicated overlapping horizontal and vertical sample counts (Table 6, [0218], input tensors are derived using the signaled overlap amount); and generate a filtered picture using the neural network post-filter based on the derived input tensor ([0174], [0175], input tensors are used for post-filtering). Chujoh is silent about wherein the filtered picture generated by the neural network post-filter does not include overlap regions. Esenlik from the same or similar field of endeavor discloses wherein the filtered picture generated by the neural network post-filter does not include overlap regions ([0346], [0368], [0463]-[0465], a cropped image which removes overlap regions is generated). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the teachings of Esenlik into the teachings of Chujoh for more efficient image encoding/decoding (Esenlik: [0006]). Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
