DETAILED ACTION
This Office Action is a response to an application filed on 05/30/2025, in which claims 1-3 are pending and ready for examination.
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 .
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 USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission.

Patent No. 12,348,733 does not disclose: the value of bi-prediction weight index information of the current block is equal to 0.
However, Zhang from the same or similar endeavor discloses: the value of bi-prediction weight index information of the current block is equal to 0 (see Zhang, paragraph 9 and 657 and Fig. 9).
It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to “obtaining residual information form a bitstream; deriving residual samples for the current block based on the residual information; and generating reconstructed samples for the current block based on the residual samples” as taught by Zhang in the decoding method taught by Patent No. 12,348,733 to reduce bandwidth and line buffers of several coding tools in video/image coding (see Zhang, paragraph 83).
Claims 1, 2, and 3 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 3, and 4 of U.S. Patent No. 12,003,735 for the same reasons mentioned above.
Allowable Subject Matter
Claims 1-3 would be allowed upon overcoming the Double Patenting rejection shown above.
