Office Action

§DP
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 . Detailed Action Response to Amendment This Office Action is in response to the correspondence on 02/03/2026. Applicant’s argument, filed on 02/03/2026 has been entered and carefully considered. Claims 1-20 are pending. Double Patenting rejection against US 12,108,058 B2 is retained based on the arguments submitted on 02/03/2026. Information Disclosure Statement This information disclosure statement (IDS) submitted on 02/03/2026. The submission is in compliance with the provisions of 37 CFR 1.97 and 37 CFR 1.98. Accordingly, the information disclosure statement is being considered by the examiner. Response to Arguments Applicant’s arguments in the 02/03/2026 Remarks have been fully considered but they are not persuasive because of the following: Regarding claims, on page 2-4 argues “fails to identify where each and every limitation …. In the reference claims”. While the applicant’s argument points are understood, the examiner respectfully disagrees it is because US 12,108,058 B2 discloses (Only clarify for Claim from Instant Application, 18/824,376, “A video processing method, comprising: determining, based on a chroma format [A video processing method, comprising: determining, based on a chroma format], whether a sub-process is enabled, wherein the sub-process is a joint coding for chroma residues (JCCR) sub-process or an adaptive color transform (ACT) sub-process [wherein the sub-process enabled flag being set to one indicates that the sub-process for processing the sequence is enabled and the sub-process enabled flag comprises a joint coding for chroma residues (JCCR) sub-process enabled flag or an adaptive color transform (ACT) sub-process enabled flag], wherein the sub-process is: enabled in response to the chroma format indicating that a chroma component is included in a sequence of frames, and disabled in response to the chroma format indicating that the chroma component is not included in the sequence [whether a chroma component is included in a sequence of frames; and signaling, based on the chroma component determination, a sub-process enabled flag to indicate whether a sub-process for processing the sequence is activated, wherein: the sub-process enabled flag is set to zero in response to the chroma component not being included in the sequence; and the sub-process enabled flag is set to one in response to the chroma component being included in the sequence]”, so, it is obvious to the ordinary skill in the art that the claim limitations are not patentably distinct as shown in the table format). Therefore, the rejection is maintained. 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 §§ 706.02(l)(1) - 706.02(l)(3) 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. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Claims 1, 11, 18, and similar dependent claims are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of Conflicting Patent PAT US 12,108,058 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the subject matter claimed in the instant application is anticipated by the Conflicting Patent and is covered by the Patent since the Patent and the application are claiming common subject matter, below is a list of limitations that perform the same function, however, different terminology may be used in both sets to describe the limitations, as follows, Claim 1 is used as an example to analyze the common subject matter: Conflicting Patent No. US 12,108,058 B2 Instant Application:-18/824,376 1. A video processing method, comprising: determining, based on a chroma format, whether a chroma component is included in a sequence of frames; and signaling, based on the chroma component determination, a sub-process enabled flag to indicate whether a sub-process for processing the sequence is activated, wherein: the sub-process enabled flag is set to zero in response to the chroma component not being included in the sequence; and the sub-process enabled flag is set to one in response to the chroma component being included in the sequence, wherein the sub-process enabled flag being set to one indicates that the sub-process for processing the sequence is enabled and the sub-process enabled flag comprises a joint coding for chroma residues (JCCR) sub-process enabled flag or an adaptive color transform (ACT) sub-process enabled flag. 1. A video processing method, comprising: determining, based on a chroma format, whether a sub-process is enabled, wherein the sub-process is a joint coding for chroma residues (JCCR) sub-process or an adaptive color transform (ACT) sub-process, wherein the sub-process is: enabled in response to the chroma format indicating that a chroma component is included in a sequence of frames, and disabled in response to the chroma format indicating that the chroma component is not included in the sequence. As demonstrated, the claim of US patent US 12,108,058 B2 anticipate the features of the claim of instant application 18/824,376. Similar rejections can be applied for Patent US 11,356,679 B2. A nonstatutory type (35 U.S.C. 101) double patenting rejection can be overcome by amending the conflicting claims so they are no longer coextensive in scope or filing of a terminal disclaimer. Conclusion THIS ACTION IS MADE FINAL. 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.
