Office Action

§102
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 . DETAIL ACTION This office action is a response to a 371 application filed -----1/25/2024, which is a national stage application of PCT/KR2022/012080 filed 8/12/2022, which claims foreign priority to KR10-2021-0107249 filed 8/13/2024. As filed, claims 1-9 are pending, wherein claim 1 is an independent claim. Information Disclosure Statement The information disclosure statement (IDS) submitted on 1/25/2024 and 4/14/2025 has been considered by the Examiner. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Should applicant desire to obtain the benefit of foreign priority under 35 U.S.C. 119(a)-(d) prior to declaration of an interference, a certified English translation of the foreign application must be submitted in reply to this action. 37 CFR 41.154(b) and 41.202(e). Failure to provide a certified translation may result in no benefit being accorded for the non-English application. Claim Rejections - 35 USC § 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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by “Conformationally constrained analogues of diacylglycerol (DAG). 14.0 Dissection of the roles of the sn-1 and sn-2 carbonyls in DAG mimetics by isopharmacophore replacement”, hereinafter Marquez. See IDS filed 4/14/2025. Regarding claim 1, Marquez teaches the following compound, which meets all the limitation of this claim. PNG media_image1.png 80 152 media_image1.png Greyscale (pg. 1760, Table 1, compound #4 Wherein: instant variables R1, R2, and R4-R8 are H; instant variable m is 0; and instant variable R3 is a C1 substituted alkyl. Claims 1-3 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chemical Abstract Registry No. 2765097-72-9, hereinafter CAS729. Applicant cannot rely upon the certified copy of the foreign priority application to overcome this rejection because a translation of said application has not been made of record in accordance with 37 CFR 1.55. When an English language translation of a non-English language foreign application is required, the translation must be that of the certified copy (of the foreign application as filed) submitted together with a statement that the translation of the certified copy is accurate. See MPEP §§ 215 and 216. Regarding claims 1-3, CAS729 teaches the following compound, which meets all the limitation of this claim. PNG media_image2.png 104 164 media_image2.png Greyscale Wherein: instant variables R1-R8 are H; and instant variable m is 0. Allowable Subject Matter Claims 4-9 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Conclusion Claims 1-3 are rejected. Claims 4-9 are objected.
