Office Action

§102 §DP
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 . DETAILED ACTION 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. Claims 1-4, 10-13 and 15 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by JP 2008-19402 A (Jan. 31, 2008) with Machine translation. JP teaches a silicone urethane(meth)acrylate comprising three (meth)acryloyl groups and two urethane groups in [0113] of page 23 (formula 20). JP teaches a silicone urethane(meth)acrylate comprising six (meth)acryloyl groups and four urethane groups in [0115] of page 23 (formula 21). The formula 20 and formula 21 would meet the silicone urethane(meth)acrylate of claim 1-4. Machine translated JP teaches a curable composition comprising the silicone urethane(meth)acrylate and a methacrylate compound in claim 1 of para. [0007] and its use as an anti-reflective film having excellent scratch and stain resistance in [0006] which would meet claims 10, 11, 13 and 15. Regarding claims 12, the recited components of claim 12 would be optional when the claim 12 is combined with claim 10 and thus they are not required Thus, the instant invention lacks novelty. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 10-15 and 19 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-12 of copending Application No. 18/874,022 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the mandatory components (a), (b) and (c) would fall within scope of the instant claim 10-15 and 19. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. CLAIM OBJECTION Claims 5-9, 16-18 and 20 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 since the examiner does not see any motivation to introduce an additional methacrylate group(s) to the example 3 taught by KR although a silicone urethane(meth)acrylate having at least three (meth)acryloyl groups and two urethane groups is known as taught by JP 2008-19402 A since KR (3D printing) and JP (anti-reflective film) teach different technology/application. Regarding claims 5-9, JP 2008-19402 A fails to teach Formula (A) of the instant claim 5 and utilization of at least one hydroxy functional silicone (meth)acrylate of the instant claim 8 Any inquiry concerning this communication or earlier communications from the examiner should be directed to TAE H YOON whose telephone number is (571)272-1128.
