DETAILED ACTION Claim(s) 1-22 are presented for examination. 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 As required by M.P.E.P.201.14(c), acknowledgement is made to applicant’s claim for priority based on application(s) KR10-2021-0102248 submitted on August 3rd, 20221. Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statement(s) (IDS) submitted on December 14th, 2023; October 15th, 2024; February 3rd, 2025; May 9th, 2025; and August 26th, 2025 follow the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Specification The abstract of the disclosure is objected to because it contains a legal phraseology “comprises …” in line 5. The form and legal phraseology often used in patent claims, such as "means" and "said," should be avoided. Correction is required. See MPEP § 608.01(b). Claim Rejections - 35 U.S.C. § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. § 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151 , or in an application for patent published or deemed published under section 122(b) , in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
