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 .
Election/Restrictions
Applicant’s election without traverse of Group II, claims 8-11, in the reply filed on August 26, 2026 is acknowledged.
Claims 1-7 and 12-15 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to nonelected inventions, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on August 26, 2026.
Claim Objections
Claim 11 is objected to because of the following informalities: in lines 5-6,
“2-methylene-1, and 3-dioxepane” should be rewritten as “2-methylene-1,3-dioxepane.”
Appropriate correction is required.
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 11 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.
Regarding claim 11, the phrase "such as" in line 6 renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d).
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.
Claims 8 and 11 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Huang et al. (CN 110746525 A), hereinafter “Huang.” For citation purposes, the English Translation powered by EPO and Google will be used.
Regarding claims 8 and 11, Huang teaches a detergent composition comprising an acrylic quaternary ammonium salt copolymer which is used as a detergent additive (see [0041]), and is prepared by polymerization of four monomers: acrylic acid, maleic anhydride, dimethyl diallyl ammonium chloride and 2-methylene-1,3-dioxane (see [0037]). The 2-methylene-1,3-dioxane (i.e., cyclic ketene acetal) can undergo free radical ring-opening polymerization with vinyl monomers (i.e., acrylic acid), and after polymerization, the main chain contains ester groups that is easily hydrolyzed and can be easily degraded by microorganisms (see [0039]).
Huang teaches the limitations of the instant claims. Hence, Huang anticipates the claims.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
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 9-10 are rejected under 35 U.S.C. 103 as being unpatentable over Huang as applied to claims 8 and 11 above.
Regarding claims 9-10, Huang teaches the features as discussed above. In addition, Huang teaches that the dosage of the acrylic quaternary ammonium salt copolymer is 0.1%-20% of the total mass of the detergent composition (see [0041]). Huang, however, fails to specifically disclose the detergent composition comprising 0.01-10 wt% of the copolymer as recited in claim 9, or 0.1-3 wt% of the copolymer as recited in claim 10.
Considering that Huang teaches 0.1%-20% by mass of the copolymer, the subject matter as a whole would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have selected the overlapping portion of the range disclosed by the reference (e.g. about 0.1-10 wt% or about 0.1-3 wt%) because overlapping ranges have been held to be a prima facie case of obviousness, see In re Malagari, 182 U.S.P.Q 549; In re Woodruff, 919 F.2d 1575, 1578, 16 USPQ2d 1934, 1936-37 (Fed. Cir. 1990); In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976). In addition, a prima facie case of obviousness exists because the claimed ranges "overlap or lie inside ranges disclosed by the prior art", see In re Wertheim, 541 F.2d 257,191 USPQ 90 (CCPA 1976; In re Woodruff; 919 F.2d 1575,16USPQ2d 1934 (Fed. Cir. 1990). See MPEP 2144.05(I).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The references are considered cumulative to or less material than those discussed above.
