Office Action

§102 §103
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 . This non-final Office action is in response to Applicant’s patent application number 18/114,364 filed on 2/27/2023. Currently, claims 1-4 are pending and examined. Drawings Color photographs and color drawings are not accepted in utility applications unless a petition filed under 37 CFR 1.84(a)(2) is granted. Any such petition must be accompanied by the appropriate fee set forth in 37 CFR 1.17(h), one set of color drawings or color photographs, as appropriate, if submitted via the USPTO patent electronic filing system or three sets of color drawings or color photographs, as appropriate, if not submitted via the via USPTO patent electronic filing system, and, unless already present, an amendment to include the following language as the first paragraph of the brief description of the drawings section of the specification: The patent or application file contains at least one drawing executed in color. Copies of this patent or patent application publication with color drawing(s) will be provided by the Office upon request and payment of the necessary fee. Color photographs will be accepted if the conditions for accepting color drawings and black and white photographs have been satisfied. See 37 CFR 1.84(b)(2). Claim Objections Claim 2 is objected to because of the following informalities: “EPDM” should be spelled out once in the claims. Appropriate correction is required. Claim Rejections - 35 USC § 102 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. Claim(s) 1 and 4 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US No. 6,943,320 to Bavett. Re claim 1: Bavett discloses a system for providing a non-corrosive surface, comprising: a concrete surface (see Abstract, col. 2, lines 46-56, Fig. 9); a metal substrate 26 coupled to the concrete surface; and a non-corrosive coating, e.g. rubber applied directly to at least one of (i) the concrete surface and (ii) the metal substrate 26, the non-corrosive coating comprising: a chemically inert polymer (i.e. rubber, col. 2, lines 9-10); and an additive (i.e. inhomogeneity 0.5-1.5, col. 4, lines 60-63) Re claim 4: further comprising a heating element 12 electrically coupled to the metal substrate 26 (Fig. 2). 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. Claim(s) 2-3 is/are rejected under 35 U.S.C. 103 as being unpatentable over US No. 6,943,320 to Bavett. Re claim 2: Bavett discloses basic structures of the claimed invention as stated above and further discloses wherein the chemically inert polymer comprises rubber (col. 2, lines 9-10) but does not disclose expressly the rubber comprises EPDM. However, it would have been obvious to one with ordinary skill before the effective filing date of the claimed invention to choose different types of rubber, e.g. EPDM rubber in order to optimize the outcome result, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 227 F.2d 197, 125 USPQ 416 (CCPA 1960). Re claim 3 Bavett discloses basic structures of the claimed invention as stated above but does not disclose expressly the non-corrosive coating comprises about 50% by volume of the additive. However, it would have been obvious to one with ordinary skill before the effective filing date of the claimed invention to have different ratios for the additive in order to maximize the desirable result, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or working ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure (see attached PTO-892).
