Office Action

§102 §103 §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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. 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. Claims 1-20 are 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. Claims 1-20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, for containing the limitation ”a quaternary compound including a quaternary ammonium cation having a total number of carbon atoms of 5 or more” in claim 1. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) is considered indefinite, since the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP 2173.05(c). Claims 2-20 are included in this rejection for being dependent upon claim 1. Appropriate correction and/or clarification is required. Claims 1-20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, for containing the limitation ”a quaternary phosphonium compound including a quaternary phosphonium cation having a total number of carbon atoms of 5 or more” in claim 1. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) is considered indefinite, since the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP 2173.05(c). Claims 2-20 are included in this rejection for being dependent upon claim 1. Appropriate correction and/or clarification is required. Claims 2-3 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, for not containing a structure for Formula (1) or Formula (2). For examination purposes, the examiner will treat the structures of Formula (1) and Formula (2) as the structures depicted in paragraph 26 of the instant specification. Claim 3 is included in this rejection for being dependent upon claim 1. Appropriate correction and/or clarification is required. Claim 5 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, for containing the limitation ”a quaternary compound including a quaternary ammonium cation having a total number of carbon atoms of 8 or more”. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) is considered indefinite, since the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP 2173.05(c). Appropriate correction and/or clarification is required. Claim 5 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, for containing the limitation ”a quaternary phosphonium compound including a quaternary phosphonium cation having a total number of carbon atoms of 8 or more”. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) is considered indefinite, since the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP 2173.05(c). Appropriate correction and/or clarification 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 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. Claims 1-20 are rejected under 35 U.S.C. 102((a)(1)) as anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over Thomas et al, US 2018/0037852. Thomas et al, US 2018/0037852, discloses a post chemical mechanical polishing formulation comprising 0.01-10% by weight of an organic amine, about 0.00005-1% by weight of cysteine, about 0.0005-1% by weight of a complexing agent, about 0.01-20% by weight of a quaternary base, and about 80-99.98% by weight of water (see abstract and paragraph 37). It is further taught by Thomas et al that suitable organic amines include monoethanolamine (see paragraph 39), that suitable quaternary bases include ethyltrimethylammonium hydroxide (see paragraph 41), that suitable complexing agents include cysteine and oxalic acid (see paragraph 42), that the formulation further contains an additional etchant, such as propylene glycol monobutyl ether (see paragraph 43), and a cleaning additive, such as polyethylene oxide (see paragraph 44), that the pH of the formulation is 7-14 (see paragraph 50), and that the formulation is used in a process to clean printed circuit boards (see paragraphs 52-68), per the requirements of the instant invention. Specifically, note Examples 1A-1D. Therefore, instant claims 1-20 are anticipated by Thomas et al, US 2018/0037852. In the alternative that the above disclosure is insufficient to anticipate the above listed claims, it would have nonetheless been obvious to the skilled artisan to produce the claimed composition, as the reference teaches each of the claimed ingredients within the claimed proportions for the same utility.
