Office Action

§112 §DOUBLEPATENT
DETAILED ACTION Response to Arguments Applicant’s arguments, see application, filed 02/26/2026, with respect to the 103 rejections have been fully considered and are persuasive. The 103 rejections have been withdrawn. Applicant's arguments filed 02/26/2026 have been fully considered but they are not persuasive. Applicant argues that the double patenting rejections are overcome due to the amendments. The examiner respectfully disagrees. The co-pending applications are being amended in an analogous manner as compared to this instant application. 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 . Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy has been filed in parent Application No. 17/695,638, filed on 03/30/2022. Information Disclosure Statement The information disclosure statement (IDS) was submitted on 01/28/2026. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 02/26/2026 has been entered. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-4, 6-9 and 11-12 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. The independent claims recite “wherein only quantization matrixes of three sizes are decoded/encoded as the second quantization matrix regardless of a block size”. This limitation has been deemed new matter. For example, applicant’s published spec para. [0084] states “In VVC, orthogonal transformation from a minimum 2x2 pixel size to a 64x64 pixel size is used, and it is also possible to adopt a configuration in which for loops from a 2x2 pixel size whose sizeId is 1 to a 64x64 pixel size whose sizeId is 6 are set, and quantization matrices respectively corresponding thereto are encoded. However, in the present embodiment, the maximum orthogonal transformation size, that is, the maximum size of the subblocks is 8x8, and thus the upper limit value of a for loops is a sizeId of 3 corresponding to the 8x8 pixel size. This enables unnecessary quantization matrix encoding to be omitted and redundant code generation to be prevented, by setting the upper limit value of the for loop based on the maximum value of the orthogonal transformation size that is actually used.” Therefore, this paragraph states that the quantization matrices have an upper limit of 8x8 due to the maximum size of the subblocks being 8x8. In other words, the quantization matrices are dependent on block size. Please clarify. The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-4, 6-9 and 11-12 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. The independent claims recite “wherein only quantization matrixes of three sizes are decoded/encoded as the second quantization matrix regardless of a block size”. This limitation is unclear. For example, applicant’s published spec para. [0084] states “In VVC, orthogonal transformation from a minimum 2x2 pixel size to a 64x64 pixel size is used, and it is also possible to adopt a configuration in which for loops from a 2x2 pixel size whose sizeId is 1 to a 64x64 pixel size whose sizeId is 6 are set, and quantization matrices respectively corresponding thereto are encoded. However, in the present embodiment, the maximum orthogonal transformation size, that is, the maximum size of the subblocks is 8x8, and thus the upper limit value of a for loops is a sizeId of 3 corresponding to the 8x8 pixel size. This enables unnecessary quantization matrix encoding to be omitted and redundant code generation to be prevented, by setting the upper limit value of the for loop based on the maximum value of the orthogonal transformation size that is actually used.” Therefore, this paragraph states that the quantization matrices have an upper limit of 8x8 due to the maximum size of the subblocks being 8x8. It is unclear why the claimed invention would utilize only 2x2, 4x4 and 8x8 quantization matrices when the block size is, for example, 32x32, 64x64 or larger. Para. [0084] (recited above) states that a sizeId of 6 would be utilized in VVC for when the block size is 64x64. Hence, the quantization matrix size used is dependent on the block size. 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 1-4, 6-9 and 11-12 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3, 5-6 and 8-9 of copending Application No. 18/910,566. This instant application is broader in claim scope and omits a limitation from the co-pending app. ‘566. Additionally, co-pending app. ‘566 claims the luma/chroma details in claim 2. This is a provisional nonstatutory double patenting rejection. Claims 1-4, 6-9 and 11-12 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3, 5-6 and 8-9 of copending Application No. 18/910,585. This instant application is broader in claim scope and omits a limitation from the co-pending app. ‘585. Additionally, co-pending app. ‘585 claims the luma/chroma details in claim 2. This is a provisional nonstatutory double patenting rejection. Claims 1-4, 6-9 and 11-12 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3, 5-9 and 11-15 of copending Application No. 18/910,615. This instant application is broader in claim scope. Additionally, co-pending app. ‘615 claims the luma/chroma details in claim 2. This is a provisional nonstatutory double patenting rejection. Allowable Subject Matter Claims 1-4, 6-9 and 11-12 would be allowable if rewritten or amended to overcome the rejection(s) under obviousness double patenting, 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), 1st paragraph and 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
