Office Action

§103 §112
Notice of Pre-AIA or AIA Status 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 2. The Office Action is in response to amendment filed on 12/08/2025. Response to Amendment 3. The amendment filed on 12/08/2025, claims 1, 2, 7, 8, 10, and 13 are amended, and claims 6, 12, and 15 are canceled without prejudice to or disclaimer of the subject matter contained therein. Further, new claims 16 and 17 are added; therefore, 1-5, 7-11, 13-14, 16-17 are pending. 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 Application No. 18838931 filed on 08/15/2024. Priority # Filling Data Country 10-2022-0020427 2022-02-16 KR 5. Response to Arguments Applicant’s arguments filed on 12/08/2025, pages 6-8 have been fully considered. Claim Rejections - 35 USC §112 Since applicant has amended the claims properly, the 112(b) rejection in the non-final office action 09/10/2025 is withdrawn. Claim Rejections - 35 USC §103 Applicant’s arguments with respect to claim under 35 U.S.C. § 103 has been fully considered. Applicant argued that the current prior arts (WU et al. (CN 114009046) and in view of Mammou et al. (US 20210090301)) does not discloses the amended limitations as: “wherein the scaling-related information includes information for identifying whether the scaling factor is applied and information for identifying the scaling factor”, since: “WU and Mammou, individually or in combination, do not disclose or suggest that the scaling-related information in the signaling information includes information for identifying whether the scaling factor is applied and information for identifying the scaling factor”. Examiner’s Response: After updating search, examiner believes that the combination of WU et al. (CN 114009046), Mammou et al. (US 20210090301), RHYU et al. (WO 2020122675) and Joshi et al. (US 20200219288) teach the aforementioned limitations in independent claims 1, 7, 13, and 16, as presented in this office action. For example, RHYU discloses that “wherein the scaling-related information includes information for identifying whether the scaling factor is applied” in fig. 11 and in page 14, as: “whether a loss scale factor is applied may be determined in consideration of compression capacity or subjective image quality”; in which, information of compression capacity or subjective image quality is the scaling-related information; Joshi, on the other hand, discloses that “the scaling-related information includes information for identifying the scaling factor” in fig. 5C, 562 (scaling engine) and paragraph 0121, “The scaling engine 562 identifies the scaling factor or the scaling threshold from the bitstream. For example, after the decoding engine 560 decodes the occupancy map information 558 to generate the occupancy map frames, the scaling engine 562 identifies the scaling factor or the scaling threshold”, in which, the occupancy map information is the scaling-related information. Claim Rejections - 35 USC § 103 6. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102 of this title, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole 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. Patentability shall not be negated by the manner in which the invention was made. 7. Claim 1, 5, 7, 11, 13-14, 16-17 are rejected are rejected under 35 U.S.C. 103 as being unpatentable over WU et al.
