Office Action

§102 §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 . The response of the applicant has been read and given careful consideration. Restriction to one of the following inventions is required under 35 U.S.C. 121: I. Claims 1-9, drawn to an acetylene composition which may be used as a photoresist underlayer, classified in G093F7/025 II. Claims 10, drawn to a layer of the cured polymer on a substrate, classified in C07C43/285 . III. Claims 11-15, drawn to processes of forming electronic devices including curing the layer, classified in G03F7/11 The inventions are independent or distinct, each from the other because: Inventions group I and group II are related as mutually exclusive species in an intermediate-final product relationship. Distinctness is proven for claims in this relationship if the intermediate product is useful to make other than the final product, and the species are patentably distinct (MPEP § 806.05(j)). In the instant case, the intermediate product is deemed to be useful as in forming three dimensional stereolithographic structures or coating on non-semiconductor substrates and the inventions are deemed patentably distinct because there is nothing of record to show them to be obvious variants. The curing is a chemical transformation. Inventions group I and group III are related as product and process of use. The inventions can be shown to be distinct if either or both of the following can be shown: (1) the process for using the product as claimed can be practiced with another materially different product or (2) the product as claimed can be used in a materially different process of using that product. See MPEP § 806.05(h). In the instant case the composition can be used to form a coating on another substrate or in a stereolithographic composition. Group II and group III would be examined together. Restriction for examination purposes as indicated is proper because all the inventions listed in this action are independent or distinct for the reasons given above and there would be a serious search and/or examination burden if restriction were not required because one or more of the following reasons apply: These different inventions have a acquired a separate status in the art as evidenced by their different classification and divergent search Applicant is advised that the reply to this requirement to be complete must include (i) an election of an invention to be examined even though the requirement may be traversed (37 CFR 1.143) and (ii) identification of the claims encompassing the elected invention. The election of an invention may be made with or without traverse. To reserve 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 restriction 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 upon the elected invention. Should applicant traverse on the ground that the inventions are not patentably distinct, applicant should submit evidence or identify such evidence now of record showing the inventions 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 inventions 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 invention. Claims 1,10 and 11 are generic to the following disclosed patentably distinct species: polyacetylene compounds including a first aromatic ring and a further aromatic heterocyclic or fused aromatic ring system. The species are independent or distinct because there are 19 moieties bounded by the language of Ar1 (19 are recited in claim 2 and in the specification at [0021]) and at least 21 moieties bounded by the language of Ar2 (21 are recited in the specification at [0023]). This makes for 399 compounds which are classified on the basis of any specific aromatic rings and any specific heteroaromatic rings they contain. 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. 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: There are 19 moieties bounded by the language of Ar1 (19 are recited in claim 2 and in the specification at [0021]) and at least 21 moieties bounded by the language of Ar2 (21 are recited in the specification at [0023]). This makes for 399 compounds which is further multiplied by the 2-5 (at least 4 different) acetylene moieties which yields a minimum of 1596 different compounds which are classified on the basis of the acetylene group,, any aromatic rings and any heteroaromatic rings. This represents a serious search burden. Applicant is advised that the reply to this requirement to be complete must include (i) an election of a species or a grouping of patentably indistinct 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 the species 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. Telephone calls were made to Jonathan D. Baskin (39,499) on June 1 and 2 of 2026 to request an oral election to the above restriction requirement, but did not result in an election being made. The examiner left telephone messages, but no callback was received. Applicant is reminded that upon the cancelation of claims to a non-elected invention, the inventorship must be corrected in compliance with 37 CFR 1.48(a) if one or more of the currently named inventors is no longer an inventor of at least one claim remaining in the application. A request to correct inventorship under 37 CFR 1.48(a) must be accompanied by an application data sheet in accordance with 37 CFR 1.76 that identifies each inventor by his or her legal name and by the processing fee required under 37 CFR 1.17(i). The examiner has required restriction between product or apparatus claims and process claims. Where applicant elects claims directed to the product/apparatus, and all product/apparatus claims are subsequently found allowable, withdrawn process claims that include all the limitations of the allowable product/apparatus claims should be considered for rejoinder. All claims directed to a nonelected process invention must include all the limitations of an allowable product/apparatus claim for that process invention to be rejoined. In the event of rejoinder, the requirement for restriction between the product/apparatus claims and the rejoined process claims will be withdrawn, and the rejoined process claims will be fully examined for patentability in accordance with 37 CFR 1.104. Thus, to be allowable, the rejoined claims must meet all criteria for patentability including the requirements of 35 U.S.C. 101, 102, 103 and 112. Until all claims to the elected product/apparatus are found allowable, an otherwise proper restriction requirement between product/apparatus claims and process claims may be maintained. Withdrawn process claims that are not commensurate in scope with an allowable product/apparatus claim will not be rejoined. See MPEP § 821.04. Additionally, in order for rejoinder to occur, applicant is advised that the process claims should be amended during prosecution to require the limitations of the product/apparatus claims. Failure to do so may result in no rejoinder. Further, note that the prohibition against double patenting rejections of 35 U.S.C. 121 does not apply where the restriction requirement is withdrawn by the examiner before the patent issues. See MPEP § 804.01. Applicant's election with traverse of group I and the compound PNG media_image1.png 95 225 media_image1.png Greyscale in the reply filed on 9/8/2026is acknowledged. The traversal is on the ground(s) that there is no search burden. This is not found persuasive because as established above, the curable composition can be used as a resist, protective coating or the like and the species are independent or distinct because there are 19 moieties bounded by the language of Ar1 (19 are recited in claim 2 and in the specification at [0021]) and at least 21 moieties bounded by the language of Ar2 (21 are recited in the specification at [0023]). This makes for 399 compounds which are classified on the basis of any specific aromatic rings and any specific heteroaromatic rings they contain and 399 compounds referred to above does not account for the fact that the formula (I) is a partial structure of the curable compound merely describing moieties which can be connected to any core/remainder of the compound. Therefore to allow a reasonably through examination, the scope of the examination needs to be limited. The requirement is still deemed proper and is therefore made FINAL. Claims 10-15 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 9/8/2026. 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 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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (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. 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 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 1-5, and 9 are rejected under 35 U.S.C. 102(a)(1) as being by Sato et al. JP 2005041938. Sato et al.

Production example 7 synthesizes PNG media_image9.png 105 302 media_image9.png Greyscale as compound G in the presence of DMSO and toluene [0043]. Coating liquid 3 combines compound C with anisole as in coating liquid 1, coating liquid 4 combines compound D and anisole as in coating liquid 1, coating liquid 6 combines compound F and anisole as in coating liquid 1 and coating liquid 7 combines compound G in N-methylpyrrolidone (NMP) [0047]. Example 7 used coating liquid 7 to coat a wafer. [0054]. Examples of the additive include coupling agents such as silane coupling agents and titanium coupling agents, catalysts such as organic peroxide, surfactants, and foam stabilizers. Coupling agents may be added to improve adhesion to the substrate, surfactants may be added to stabilize coatability, and organic peroxides and other catalysts may be added to reduce the crosslinking temperature of the monomers [0029]. The composition for forming an organic insulating film of the present invention contains a compound having at least three —C≡CH groups in the molecule, but may further contain an organic solvent to form a coating solution. The organic solvent is not particularly limited as long as it can dissolve a compound having at least three —C≡CH groups in the molecule. Examples of the organic solvent include alcohol solvents such as methanol, ethanol, isopropanol, 1-butanol, 2-ethoxymethanol, 3-methoxypropanol, acetylacetone, methylethylketone, methylisobutylketone, 3-pentanone, 2-heptanone, 3 -Ketone solvents such as heptanone and cyclohexanone, propyl acetate, butyl acetate, isobutyl acetate, pentyl acetate, methyl propionate, ethyl propionate, methyl butyrate, propylene glycol monomethyl ether acetate, ethyl lactate and other ester solvents, diisopropyl ether, Ether solvents such as dibutyl ether, dioxane, anisole, phenetol, veratrol, diphenyl ether, benzene, toluene, mesitylene, ethylbenzene Aromatic hydrocarbon solvents, halogen solvents such as chloroform, chlorobenzene, dichloroethylene, trichloroethylene, N, N-dimethylformamide, N, N-diethylformamide, N, N-dimethylacetamide, N-methylpropionamide, N- Examples include amide solvents such as methylpyrrolidone, and aliphatic hydrocarbon solvents such as pentane, hexane, and heptane, and these are preferably used because they are easily available industrially [0026] The position of the examine is that coating solutions containing compounds C, D, F or G meet the claims as they include a compound bounded by the claims in a solvent. The coating solution including compound G includes the elected species I-1. As these solutions include multiple compounds each of which includes multiple ethynyl groups, the examiner holds that these additional compounds bounded by formula (I) are present as crosslinkers.
