Office Action

§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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114 was filed in this application after a decision by the Patent Trial and Appeal Board, but before the filing of a Notice of Appeal to the Court of Appeals for the Federal Circuit or the commencement of a civil action. 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examination under 37 CFR 1.114 and the fee set forth in 37 CFR 1.17(e) has been timely paid, the appeal has been withdrawn pursuant to 37 CFR 1.114 and prosecution in this application has been reopened pursuant to 37 CFR 1.114. Applicant’s submission filed on 28 July 2026 has been entered. Election/Restrictions Newly submitted claims 22-27 are directed to an invention that is independent or distinct from the invention originally claimed for the following reasons: Claims 22-27 (i.e. Group II – classified in C04B 35/62894) are directed to a method of making a thermal spray powder and are related to originally examined product claims 1-8 (i.e. Group I – classified in C04B 14/324) as process of making and product made. The inventions are distinct if either or both of the following can be shown: (1) that the process as claimed can be used to make another and materially different product or (2) that the product as claimed can be made by another and materially different process (MPEP § 806.05(f)). In the instant case the process of Group II may form particles with coating layer thicknesses of greater than an atomic thickness and/or the particles of Group I may be formed by CVD, etc. in the alternative to the recited fluidizing process. 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: The inventions have acquired a separate status in the art in view of their different classification, the inventions have acquired a separate status in the art due to their recognized divergent subject matter, and/or the inventions 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 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. Since applicant has received an action on the merits for the originally presented invention, this invention has been constructively elected by original presentation for prosecution on the merits. Accordingly, claims 22-27 are withdrawn from consideration as being directed to a non-elected invention. See 37 CFR 1.142(b) and MPEP § 821.03. To preserve a right to petition, the reply to this action must distinctly and specifically point out supposed errors in the restriction requirement. Otherwise, the election shall be treated as a final election without traverse. Traversal must be timely. Failure to timely traverse the requirement will result in the loss of right to petition under 37 CFR 1.144. If claims are subsequently added, applicant must indicate which of the subsequently added 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. Claim Objections Claims 5-6 are objected to because of the following informalities: Claims 5-6 state the status identifier of “Prevopusly Presented”. Appropriate correction is required. See MPEP 714 (II)(C)(A). 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. Claims 3, 7-8, and 21 are rejected under 35 U.S.C. 112(b) 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 3 recites an individual layer thickness for alumina and silica being up to 10 nm and a broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 3 recites the broad recitation up to 10 nm, and the claim also recites atomic thicknesses for the alumina and silica which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Claims 7-8 recites where the at least one alumina layer defines a first thickness and the at least one silica layer defines a second thickness and/or a ratio being 8 and this renders the claims indefinite as the claims sets forth where the thicknesses are monolayers of atomic thickness so it is unclear how the 1st and 2nd thicknesses relate to the atomic thicknesses or ratio thereof. Clarification is required. Claim 21 recites where the individual layer thicknesses of alumina and silica of 2-5 angstroms and “atomic thickness” is a specific value and it is unclear how it can simultaneously also be a range. Clarification is required. Allowable Subject Matter Claims 1-2, 4-6, and 28 are allowed. The following is a statement of reasons for the indication of allowable subject matter: The closest prior art to the instant claims is that of Chaouki (US 2014/0206525 – previously cited). Chaouki differs in the thickness of the silica and alumina layers has a minimum of 1 nm (Paragraph 84) which is outside the claimed atomic monolayer thicknesses and this would not have been obvious to one of ordinary skill in the art. Response to Arguments Applicant’s arguments, see remarks p.5, 2nd paragraph, filed 28 July 2026, with respect to 35 USC 103 have been fully considered and are persuasive. The rejection of claims 1-8 and 21 has been withdrawn. As outlined above, applicant has amended the claims beyond the teachings of Chaouki.
