Office Action

§DP
DETAILED ACTION 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 filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual 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/apply/applying-online/eterminal-disclaimer. Claims 1–18 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1–17 of U.S. Patent No. 12,170,793 B2 in view of Bross et al., “Versatile Video Coding (Draft 8),” JVET-Q2001-vE, 17th Meeting: Brussels, BE, January 2020. The subject matter of the instant claims substantially overlaps the subject matter of the reference patent’s claims except with respect to the additional feature in the last limitation of representative claim 1, which is a nominal recitation of a well-known feature in the prior art drawn to ALF APS luma clipping information. Bross’s Section 7.4.3.19 (pg. 127 et seq.) teaches ALF APS luma ALF filter information, filter coefficient information, and clipping information and associated flags such that one skilled in the art would consider the instant claims obvious in view of the reference claims in view of the further teachings of Bross. Claims 1–18 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1–18 of copending Application No. 18/943,161 in view of Bross et al., “Versatile Video Coding (Draft 8),” JVET-Q2001-vE, 17th Meeting: Brussels, BE, January 2020 and Kim (US 2019/0082178 A1). The subject matter of the instant claims substantially overlaps the subject matter of the reference patent’s claims except with respect to the last limitations of representative claims 1 wherein the instant claims merely recite the use of ALF APS luma clipping information whereas the reference claims merely recite the use of the PPS, both of which are nominal recitations of well-known features in the prior art. Kim’s paragraph [0025] teaches a picture parameter set (PPS) and Bross’s Section 7.4.3.19 (pg. 127 et seq.) teaches ALF APS luma ALF filter information, filter coefficient information, and clipping information and associated flags such that one skilled in the art would consider the instant claims obvious in view of the reference claims in view of the further teachings of Kim and Bross. This is a provisional nonstatutory double patenting rejection. Claims 1–18 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1–18 of copending Application No. 18/943,168 in view of Bross et al., “Versatile Video Coding (Draft 8),” JVET-Q2001-vE, 17th Meeting: Brussels, BE, January 2020 and Kim (US 2019/0082178 A1). The subject matter of the instant claims substantially overlaps the subject matter of the reference patent’s claims except with respect to the last limitations of representative claims 1 wherein the instant claims merely recite the use of ALF APS luma clipping information whereas the reference claims recite slice location information found in the PPS, both of which are nominal recitations of well-known features in the prior art. Kim’s paragraph [0434] teaches a slice address in a picture parameter set (PPS) and Bross’s Section 7.4.3.19 (pg. 127 et seq.) teaches ALF APS luma ALF filter information, filter coefficient information, and clipping information and associated flags such that one skilled in the art would consider the instant claims obvious in view of the reference claims in view of the further teachings of Kim and Bross. This is a provisional nonstatutory double patenting rejection. Claims 1–18 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1–18 of copending Application No. 18/943,189 in view of Bross et al., “Versatile Video Coding (Draft 8),” JVET-Q2001-vE, 17th Meeting: Brussels, BE, January 2020. The subject matter of the instant claims substantially overlaps the subject matter of the reference patent’s claims except with respect to the last limitations of representative claims 1 wherein the instant claims merely recite the use of ALF APS luma clipping information whereas the reference claims recite a flag for indicating weighted prediction parameters could be in a picture header, both of which are nominal recitations of well-known features in the prior art. Bross’s page 117 teaches the wp_info_in_ph_flag “specifies that weighted prediction information may be present in the PH syntax structure” and Bross’s Section 7.4.3.19 (pg. 127 et seq.) teaches ALF APS luma ALF filter information, filter coefficient information, and clipping information and associated flags such that one skilled in the art would consider the instant claims obvious in view of the reference claims in view of the further teachings of Bross. This is a provisional nonstatutory double patenting rejection. Claims 1–18 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1–18 of copending Application No. 18/943,199 in view of Bross et al., “Versatile Video Coding (Draft 8),” JVET-Q2001-vE, 17th Meeting: Brussels, BE, January 2020. The subject matter of the instant claims substantially overlaps the subject matter of the reference patent’s claims except with respect to the last limitations of representative claims 1 wherein the instant claims merely recite the use of ALF APS luma clipping information whereas the reference claims recite an explicit scaling list enabled flag for the picture, both of which are nominal recitations of well-known features in the prior art. Bross’s pages 48 and 121 teach a ph_explicit_scaling_list_enabled_flag controlling whether to decode a scaling list APS ID and Bross’s Section 7.4.3.19 (pg. 127 et seq.) teaches ALF APS luma ALF filter information, filter coefficient information, and clipping information and associated flags such that one skilled in the art would consider the instant claims obvious in view of the reference claims in view of the further teachings of Bross. It appears 18/943,199 has no support for the explicit scaling list feature recited in claim 1. This is a provisional nonstatutory double patenting rejection. Claim Objections Claim 12 is objected to for the following informality: Claim 12 is objected to for stating in the preamble “a method of decoding” when the claim is clearly drawn to a method of encoding. Appropriate correction is required. Compare claim 11, which has an identical preamble, but is clearly drawn appropriately to decoding, whereas claim 12 is not. Allowable Subject Matter Claims 1–18 are indicated as allowable subject to filing a terminal disclaimer to overcome the double patenting rejections, supra. The following is a statement of reasons for the indication of allowable subject matter: Examiner was unable to find a teaching or suggestion in the prior art linking the approach of signaling the picture header in the slice header, which dictates that only a single slice is included in the picture, with the claimed features of determining there is only a single slice in the picture when raster slice scan is enabled, a number of tiles in the picture is greater than one, and the number of tiles in a slice is equal to a number of tiles in the picture AND wherein the APS ID signaling structure for weighted prediction and adaptive loop filter is utilized as claimed. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
