Office Action

§102
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 . Detailed Action A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 12/8/25 has been entered. Claims 1-12 are pending in this application. Claims 1-8 and 12 stand withdrawn. Claim 11 no longer read upon the cited specie in the art rejection below. The MPEP- 803.02 states, “If prior art is then found that anticipates or renders obvious the Markush-type claim with respect to a nonelected species, the Markush-type claim shall be rejected and claims to the nonelected species held withdrawn from further consideration. The prior art search, however, will not be extended unnecessarily to cover all nonelected species.” Thus claim 11 is hereby withdrawn. However, claim 10 now reads on the cited specie in the art rejection below. Thus claim 10 is hereby rejoined. Thus claims 9 and 10 are being examined in this Office Action and claims 1-8 and 11-12 are withdrawn. In view of applicant's amendments to the claims filed 12/8/25, the 35 USC 102 rejection by Jia et al. has been withdrawn. However, a new 102 rejection is now applicable as described below. Priority The applicant claims benefit as follows: PNG media_image1.png 102 442 media_image1.png Greyscale Applicant’s claim for the benefit of a prior-filed application under 35 U.S.C. 119(e) or under 35 U.S.C. 120, 121, 365(c), or 386(c) is acknowledged. Applicant has not complied with one or more conditions for receiving the benefit of an earlier filing date under 35 U.S.C. 119(e) or 120 as follows: The later-filed application must be an application for a patent for an invention which is also disclosed in the prior application (the parent or original nonprovisional application or provisional application). The disclosure of the invention in the parent application and in the later-filed application must be sufficient to comply with the requirements of 35 U.S.C. 112(a) or the first paragraph of pre-AIA 35 U.S.C. 112, except for the best mode requirement. See Transco Products, Inc. v. Performance Contracting, Inc., 38 F.3d 551, 32 USPQ2d 1077 (Fed. Cir. 1994). The disclosure of the prior-filed applications, Application No. 17073367 and 62916859, fails to provide adequate support or enablement in the manner provided by 35 U.S.C. 112(a) or pre-AIA 35 U.S.C. 112, first paragraph for one or more claims of this application. These applications do not disclose applicant’s surfactant or its structure. Thus, the priority date of claims 9 and 10 is 06/23/2022. 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 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 the AIA 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. 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. Claims 9 and 10 are rejected under AIA 35 U.S.C. 102(a)(1) and/or 102(a)(2) as being anticipated by Gaertner (US 3102893, published Sep 3, 1963). Gaertner teaches the following polyether substituted glycidyl ether: Sodium 3-[1-(n-hexadecyloxy)-2-propoxy]-2-hydroxy-1-propanesulfonate (see column 10, lines 45-47; Example 1) Thus Gaertner compound reads on applicant’s surfactant structure in claim 9 when n = 3, R1 = H, R = 2-ethylhexane (C8 alkyl branched acyclic), and the salt is Na+. Therefore these claims are fully met. Conclusion No claim is allowed.
