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 . Election/Restrictions Applicant’s election without traverse of Group I, claims 1-13 and 15, in the reply filed on 10/28/2025 is acknowledged. Claims 14 and 16-20 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to nonelected inventions, there being no allowable generic or linking claim. 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. (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. Claim(s) 1-5, 11 and 15 is/are rejected under 35 U.S.C. 102((a)(1)/(a)(2)) as being anticipated by Parker et al. (USPN 5,373,578). In col. 2, lines 5-28 and col. 7, lines 7-20, Parker et al. teach a curable coating composition comprising 50-80% of a urethane acrylate oligomer with 1-20% of a hydrocarbon component represented by polytetrahydrofurandiol and about 2% of a photoinitiator. Thus, the requirements for rejection under 35 U.S.C. 102((a)(1)/(a)(2)) are met. Allowable Subject Matter None of the prior art is found to teach or sufficiently suggest the particular furan based reactive diluents of claims 6-10, 12 and 13 of the present curable composition with the urethane acrylate oligomer and photoinitiator. Claims 6-10, 12 and 13 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.
