Office Action

§102 §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 . 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. Claim 24 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 24 recites the limitation "the at least one difunctional polyol" in line 1. There is insufficient antecedent basis for this limitation in the claim. For the purpose of further examination, the claim will be interpreted as referring to the polyol of claim 16. Claim Rejections - 35 USC § 102 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. Claims 16-26 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Wittwer et al. (US 2022/0186069). Considering Claims 16 and 18-25: Wittwer et al. teaches a polyurethane coating composition comprising a first component that comprises 7.5 weight percent of castor oil and 9.9 weight percent of dipropylene glycol/polyols; 2.0 weight percent of trifunctional polypropylene glycol/a triol; optionally less than 2 weight percent of plasticizer (¶0118); 9 weight percent of calcium carbonate; soy lecithin/a dispersant; a silane/adhesion promoter; and pyrogenic silica/a rheology modifier; and dibutyl tin dilaurate/a catalyst (Table 2); and a second component comprising polymeric diphenyl methylene diisocyanate/an aromatic diisocyanate (Table 2). Wittwer et al. does not teach applying the waterproofing polyurethane composition onto an article with a pre-applied waterproofing membrane. However, this is a statement of intended use. If the body of a claim fully and intrinsically sets forth all of the limitations of the claimed invention, and the preamble merely states, for example, the purpose or intended use of the invention, rather than any distinct definition of any of the claimed invention’s limitations, then the preamble is not considered a limitation and is of no significance to claim construction. Shoes by Firebug LLC v. Stride Rite Children’s Grp., LLC, 962 F.3d 1362, 2020 USPQ2d 10701 (Fed. Cir. 2020) (The court found that the preamble in one patent’s claim is limiting but is not in a related patent); Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1305, 51 USPQ2d 1161, 1165 (Fed. Cir. 1999). See MPEP § 2111.02. The Office realizes that all of the claimed effects or physical properties are not positively stated by the reference(s). However, the reference(s) teaches all of the claimed ingredients, in the claimed amounts, and teaches the composition as being made by a substantially similar process. The original specification does not provide any disclosure on how to obtain the claimed properties outside the components of the composition itself. Therefore, the claimed effects and physical properties, i.e. the Young’s modulus or peel adhesion with hardened concrete, would necessarily arise from a composition with all the claimed ingredients in the claimed amounts. "Products of identical chemical composition can not have mutually exclusive properties." In re Spada, 911 F.2d 705, 709, 15 USPQ2d 1655, 1658 (Fed. Cir. 1990). A chemical composition and its properties are inseparable. Therefore, if the prior art teaches the identical chemical structure, the properties applicant discloses and/or claims are necessarily present. If it is the applicant’s position that this would not be the case: (1) evidence would need to be provided to support the applicant’s position; and (2) it would be the Office’s position that the application contains inadequate disclosure that there is no teaching enabling a person of ordinary skill in the art to obtain the claimed properties with only the claimed ingredients, absent undue experimentation. Considering Claim 17: Wittwer et al. teaches that the triol can be trimethylolpropane (¶0069). Considering Claim 26: The means of applying the hardened concrete is a statement of intended use. If the body of a claim fully and intrinsically sets forth all of the limitations of the claimed invention, and the preamble merely states, for example, the purpose or intended use of the invention, rather than any distinct definition of any of the claimed invention’s limitations, then the preamble is not considered a limitation and is of no significance to claim construction. Shoes by Firebug LLC v. Stride Rite Children’s Grp., LLC, 962 F.3d 1362, 2020 USPQ2d 10701 (Fed. Cir. 2020) (The court found that the preamble in one patent’s claim is limiting but is not in a related patent); Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1305, 51 USPQ2d 1161, 1165 (Fed. Cir. 1999). See MPEP § 2111.02. Response to Arguments Applicant’s arguments with respect to claims 16-26 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
