DETAILED ACTION 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 . This Office Action responses to the Application filed on 03/03/2025. Priority 1. 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. KR10-2022-0115079, filed on 09/13/2022. Response to Amendment The Applicant’s Preliminary Amendment filed on 3/11/2013 in which claims 14 has been canceled and entered of record. Claims 1-13 are pending for examination. Requirement for Information Examiner requests under 37 CFR 1.105 the Applicant submit with the response to this Office Action (1) the legal status of any co-pending or related foreign patent application filed by the assignee or inventor(s) of this instant case and that is relevant to the prosecution of this case, and (2) the international search report, if any, of the copending or related foreign patent application. This request is necessary for the Examiner to consider possible foreign or non-patent literature that may be germane to patentability of the claimed invention. Applicant is reminded replies to requirements for information must be complete and filed within the time period set including any extension. Failure to reply within the time period set will result in the abandonment of the application. MPEP § 704.12. Claim Rejections - 35 USC § 112 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 1-13 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. Regarding claims 1, 7-8, the claim drafting is lack of clarity. Under 37 CFR 1.75 (i), a claim sets forth a plurality of elements or steps, each element or step of the claim should be separated by a line indentation. There may be plural indentations to further segregate subcombinations or related steps. See MPEP § 608.01. The independent claims do not have further indentations to further segregate subcombinations or related steps. For examination purpose, the rejections are based on best understood. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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, 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. Claim(s) 1-2, 4-9, and 11-13 is/are rejected under 35 U.S.C. 103 as being unpatentable over PARK et al., (WO2020153586), hereinafter PARK.
