Office Action

§102 §103 §112
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 . Election/Restrictions Restriction to one of the following inventions is required under 35 U.S.C. 121. This application contains claims directed to the following patentably distinct species: Species A: drawn to a photovoltaic device/solar cell, classified in H10K30/57, H10K85/50, Y02E10/549. Species B: drawn to light emitting device/OLED, classified in H10K59/10. This application contains claims directed to the following patentably distinct species A-B. The species are independent or distinct because claims to the different species recite the mutually exclusive characteristics of such species. In addition, these species are not obvious variants of each other based on the current record. Applicant is required under 35 U.S.C. 121 to elect a single disclosed species, or a single grouping of patentably indistinct species, for prosecution on the merits to which the claims shall be restricted if no generic claim is finally held to be allowable. Currently, claims 10-11 are generic. There is a serious search and/or examination burden for the patentably distinct species as set forth above because at least the following reason(s) apply: The species have acquired a separate status in the art in view of their different classification. The species have acquired a separate status in the art due to their recognized divergent subject matter, and The species require a different field of search (e.g., searching different classes/subclasses or electronic resources, or employing different search strategies or search queries). Applicant is advised that the reply to this requirement to be complete must include (i) an election of a species to be examined even though the requirement may be traversed (37 CFR 1.143) and (ii) identification of the claims encompassing the elected species or grouping of patentably indistinct species, including any claims subsequently added. An argument that a claim is allowable or that all claims are generic is considered nonresponsive unless accompanied by an election. The election may be made with or without traverse. To preserve a right to petition, the election must be made with traverse. If the reply does not distinctly and specifically point out supposed errors in the election of species requirement, the election shall be treated as an election without traverse. Traversal must be presented at the time of election in order to be considered timely. Failure to timely traverse the requirement will result in the loss of right to petition under 37 CFR 1.144. If claims are added after the election, applicant must indicate which of these claims are readable on the elected species or grouping of patentably indistinct species. Should applicant traverse on the ground that the species, or groupings of patentably indistinct species from which election is required, are not patentably distinct, applicant should submit evidence or identify such evidence now of record showing them to be obvious variants or clearly admit on the record that this is the case. In either instance, if the examiner finds one of the species unpatentable over the prior art, the evidence or admission may be used in a rejection under 35 U.S.C. 103 or pre-AIA 35 U.S.C. 103(a) of the other species. Upon the allowance of a generic claim, applicant will be entitled to consideration of claims to additional species which depend from or otherwise require all the limitations of an allowable generic claim as provided by 37 CFR 1.141. During a telephone conversation with Applicant’s representative, Leea Susanne Somersalo, on 12/23/2025, a provisional election was made with traverse to prosecute the invention of species A, e.g. a photovoltaic device. Affirmation of this election must be made by applicant in replying to this Office action. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (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. Claims 13-14 and 16-19 are 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 13 depends on claim 10 and recites “electron transporting layer” in line 2, while claim 10 also recites “an electron transporting layer” in lines 1-2. It is unclear if “electron transporting layer” recited in claim 13 is the same as or different from “an electron transporting layer” recited in claim 10. Claims 14, 16-19 are rejected on the same ground as claim 13.

Claim Rejections - 35 USC § 103 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 9 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Bayindir et al. or Dong et al. as applied to claim 1 above, in view of Jung et al. (“Non-Fullerene Organic Electron-Transporting Materials for Perovskite Solar Cells”). Regarding claim 9, Bayindir et al. or Dong et al. discloses a compound as in claim 1 above. Bayindir et al. or Dong et al. does not disclose a composition comprising the compound as in claim 1 above and a filler molecule combined with the compound molecularly, wherein the filler molecule is at least one kind of molecules as claimed. Jung et al. discloses combining the NDI with a filler molecule of thiophene (see fig. 2) to provide an electron transporting material for the device to significantly improve device operational stability under ambient condition (see pages 3884-3885). Thiophene is a molecule with an anchoring group, e.g. thiophene. It would have been obvious to one skilled in the art before the effective filing date of the claimed invention to modify the NDI of Bayindir et al. or Dong et al. by incorporating thiophene molecule filler such as thiophene to significantly improve device operational stability under ambient condition as taught by Jung et al. Regarding claim 20, modified Bayindir et al. or Dong et al. discloses a compound as in claim 9 above, wherein the NDI is an electron transporting layer for an optoelectronic device (see fig. 2 of Jung et al.). Claim(s) 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Dong et al. as applied to claim 17 above, in view of Ono et al. (“Progress on Perovskite Materials and Solar Cells with Mixed Cations and Halide Anions”). Regarding claim 18, Dong et al. discloses an optoelectronic device as in claim 17 above, and teaches the cation A is selected from at least one of ammonium (CH3NH3 or C4H9NH3) or amidinium (CH2=CHNH2), Cs, Rb, K and the X is selected from at least one of halogen or pseudohalogens such as SCN- (see [0084-0085] and [0098-0099] of the original document and the translation). Dong et al. does not explicitly disclose the perovskite being a mixed perovskite-type structure having formula (III) as claimed. Ono et al. teaches mixed perovskite FA0.85MA0.15PbI2.55Br0.45 would provide a perovskite with high efficiency (see fig. 1(b)), which has y=0.15 and z=0.45. 0.15 is right within the claimed range of 0.1 and 0.9, and 0.45 is right within the claimed range of 0.2 and 2. It would have been obvious to one skilled in the art before the effective filing date of the claimed invention to have used the mixed perovskite such as FA0.85MA0.15PbI2.55Br0.45 to obtain a photovoltaic device (or the solar cell) with high power conversion efficiency as taught by Ono et al.
