DETAILED ACTION
This action is in response to application 19/068,977 filed on 03/03/2025.
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
3. 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 obviousness-type 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); and 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 a nonstatutory double patenting ground provided the conflicting application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement.
Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b).
4. Claims 1-20 are rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claims 1-10 of U.S. Patent No. 12,278,996 B2 in view of Chen et al. (Chen”) (US Pub. No.: 2013/0215959 A1).
Furthermore, although the conflicting claims at issue are not identical, they are not patentably distinct from each other because U.S. Patent No.: 12,278,996 B2 claims:
Instant Application: 19/068,977
Note: bold and underlined fonts means same features between instant application and conflicting appl.

However, examiner notes that Chen et al. (Chen”) (US Pub. No.: 2013/0215959 A1) teaches the unique limitations in the instant application regarding an in-loop filtering implementation method for decoding and encoding (see title, abstract, paragraph [0005]), and in-loop filtering implementation computer program (see paragraph [0027]) executed by at least one the processor (see paragraph [0027]), the processor (see paragraph [0027]) is caused to: perform, based on at least two colour components (see fig. 6 unit 612 and unit 614, e.g. “Cb and Cr”) of a to-be-filtered picture (see fig. 1A, paragraphs [0021] and [0025], where the in-loop filtering process for a chroma FU may have to wait after information for all luma FUs of the picture has been received), component processing (see fig. 6, paragraphs [0025-0026]) on each of the at least two colour components (see fig. 6 unit 612 and unit 614, e.g. “Cb and Cr”); performing in-loop filtering processing (see abstract, paragraphs [0024-0025) to obtain at least one filtered colour component (see paragraph [0026]) of the to-be-filtered picture (see fig. 1A, paragraphs [0021] and [0025]).
Therefore, it 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 could recognize the advantage of providing a loop filtering implementation method and apparatus, and computer storage medium by modifying Wan’s teachings in the present US Patent No.: 12,278,996 B2 for the purpose of performing preset filtering processing on the reconstructed picture, and taking the picture after preset filtering as the to-be-filtered picture, thereby improving compression efficiency.
