Office Action

§102 §112
DETAILED ACTION Examiner’s Notes 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and the fee set forth in 37 CFR 1.1 7(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 09/10/2026 has been entered. Remarks Claims 1-59 are canceled. Claims 63, 65, and 70 are amended. Claims 60-92 are pending. Claim Objections Claim 91 is objected to because of the following informality: Claim 91 is objected to because of the informality; The claimed scope of claim 91 is the same as the claimed scope of claim 90. Examiner suggests canceling claim 91. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112: (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 75 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. Claim 75 recites “C1-10 alcohol” in line 3. It is unclear as to what Applicant intends “C1-10 alcohol” to further limit. For the purpose of this office action, the recitation will be treated as if it recites “C1-C10 alcohol”. Appropriate correction is required. Allowable Subject Matter Claims 60-92 would be allowable if rewritten or amended to overcome the claim objection and the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. The following is an examiner’s statement of reasons for allowance: the prior art taken alone or in combination fails to anticipate or fairly suggest the limitations of the claims, in such a manner that a rejection under 35 USC 102 or 103 would be proper. The prior art fails to teach a combination of all the claimed features as presented in independent claim 60. Regarding claim 60, BAI (Enhancing stability and efficiency of perovskite solar cells with crosslinkable silane-functionalized and doped fullerene) teaches a method for preparing a perovskite solar cell comprising -dispersing a functionalized material in a solvent, - depositing a deposit composition on a perovskite layer, - heating the deposit composition. But, the prior art fails to explicitly teach a combination of all the claimed features including “wherein the material of the functionalized material comprises one or more of a metal oxide, a doped metal oxide, TiO2, SnO2, NiOX, CuO, ZnO, Zn2SO4, W03, In2O3, SrTiO3, Nb2O5, BaSnO3,Y:SnO2, Cu:NiOx, Coo, PC61BM, or PC71BM”, as claimed.
