Office Action

§103
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 . 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 2/3/2026 has been entered. 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. Claim(s) 1,3-6,12,14, is/are rejected under 35 U.S.C. 103 as being unpatentable over (JP S639956 A) in view of Shei et al (US 20050168127) in view of Mancini et al (US 20050079650) Regarding Claim 1, (JP S639956 A) discloses (Drawing 10) a frame (12) having a through hole (the gap between 12); and a sealing resin (19) disposed to close the through hole entirely. (JP S639956 A) does not disclose the sealing resin is a light-absorbing film including a light-absorbing compound and wherein an average Young's modulus of the light-absorbing film measured by continuous stiffness measurement is 2.5 GPa or less.
