Office Action

§102
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 . Priority 2. The instant application is a national stage entry of PCT/CA2023/050358, filed March 17, 2023 which claims priority to U.S. Provisional Application no. 63/321,375, filed March 18, 2022. Status of Claims 3. Claims 1-4, 8-13,18-21, 25, 30-31, and 36-38 are pending and under consideration in the instant application. Claim Objections 4. Claims 37 and 38 are objected to for depending on a rejected base claim. Claim Rejections - 35 USC § 102 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. 5. 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 6. Claims 30-31 and 36 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Park et al. [Park, Hyan, Bong. Sesterterpenoid and Steroid Metabolites from a Deep-Water Alaska Sponge Inhibit Wnt/-Catenin Signaling in Colon Cancer Cells. Marine Drugs. 2018, 16, 297; doi:10.3390/md16090297 www.mdpi. Pg 1-15]. Park et al. teaches compound 1 which anticipates the instant claims: PNG media_image1.png 172 278 media_image1.png Greyscale wherein R2 is OC(=O)CH3, R3 is H, R4 is CH=C(CH3)CH2CH=CHC(=CH)CH3.
