Office Action

§102
DETAILED ACTION Final 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 . Response to Amendment The amendment filed on 05/14/2025 is entered and acknowledged by the Examiner. Claims 1, 5 and 6 have been amended. Claim 4 has been canceled. Claims 1-3 and 5-16 are currently pending in the instant application. The rejection of claims 1-3 and 5-16 under 35 U.S.C. 102(a)(1) as being anticipated by Shu (JP 2020138996 A) is withdrawn in view of Applicant’s amendment and remark. (New Grounds of Rejection) 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)(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. Claims 1-3 and 5-16 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by EP 3882286 (hereinafter Hamakubo). Hamakubo discloses a resin composition includes a base resin containing a urethane (meth)acrylate oligomer, a monomer, a photopolymerization initiator, a silane coupling agent, and surface-modified inorganic oxide particle (See [0020] and [0021]). The urethane (meth)acrylate oligomer of Hamakubo is a thermoset resin as claimed. The surface-modified inorganic oxide particle of Hamakubo is an inorganic filler as claimed. Hamakubo further discloses that the monomer includes a (meth)acryloyl compound such as 1,6-hexanediol di(meth)acrylate (See [0027] and [0049]). The 1,6-hexanediol di(meth)acrylate of Hamakubo is commonly known in the chemistry field to have a molecular weight of about 254 g/mol and exist as a clear liquid at room temperature (25°C). Moreover, the 1,6-hexanediol di(meth)acrylate of Hamakubo is commonly known to have a general chemical structure PNG media_image1.png 174 682 media_image1.png Greyscale that includes two (meth)acryloyl groups as the claimed component (B). Hamakubo discloses that the monomer (claimed component B) is 1-60 mass% of the total mass of base resin (See [0046]). The content of monomer overlaps the claimed content of component B to the total mass of component A, B and C (the balance of base resin components). Hamakubo discloses that the base resin further comprises an epoxy (meth)acrylate oligomer having two or more glycidyl groups (See [0041]). The epoxy (meth)acrylate oligomer of Hamakubo is an elastomer having molecular weight of more than 1,000. Hamakubo discloses that the resin composition is useful for forming a resin layer (resin film). The resin layer 16 forming a primary layer 14 of about 60-70 um and a secondary layer 15 of about 10-50 um (See [0059]; Figure 1). The resin layer 16 has thickness is 80 um or more as claimed. In view of the foregoing, the above claims have failed to patentably distinguish over the applied art. 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 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. Response to Arguments Applicant’s arguments with respect to the claim(s) above 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. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
