Office Action

§103
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 Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 02/26/2026 has been entered. Response to Arguments Applicant’s arguments with respect to claims 1-15 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Rejections - 35 USC § 103 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. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1-2, 4, 6, 9-10, 13 and 15 are rejected under 35 U.S.C. 103 as being unpatentable over Fukuda (US 2017/0320295) in view of Henry (US 2015/0301253) Regarding claim 1, Fukuda discloses a functionalized optical article (see Fig 2), comprising: an optical lens including at least one polymerized monomer formulation (see Fig 2; Para [0066]; a base lens 1 may comprise polymerized formulations); a functional laminate including a functional film and at least one thermoplastic film layer attached to at least one side of the functional film (see Fig 2; Para [0072]; a functional laminate comprises cured layer 2 and inorganic oxide layer 3; examiner interprets the at least one film layer to be the cured layer 2 (contains urethane methacrylate, a thermoplastic) and the functional film the inorganic oxide layer 3); and a primer coating deposited on at least one external surface of the functional laminate (see Fig 2; Para [0153-0176]; primer layer 4 disposed on a surface of laminate 2/3), wherein said primer coating includes, prior to curing: at least one acrylic polymer (see Fig 2; Para [0154]; methacryl resin may be used), at least one urethane acrylate oligomer (see Fig 2; Para [0155]; a polyurethane with an acryl component is equivalent to an urethane acrylate oligomer), at least one reactive component (see Fig 2; Para [0154]; methacryl resin may be used and is consisted a reactive component); and at least one solvent (see Fig 2; Para [0176]; a solvent may be used in the primer coating).
