Office Action

§102 §103 §112
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 . 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. Specification The specification and drawings have been reviewed and no clear informalities or objections have been noted. 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 3 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 3 recites the limitation "the aluminophosphate-type zeolite" in lines 1-2 . There is insufficient antecedent basis for this limitation in the claim. As best understood, this recitation of aluminophosphate-type zeolite appears to be referencing the aluminophosphate-type zeolite recited in claim 2 and will be examined as such. 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. Claim(s) 1-2 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Park (US 6,503,661). Regarding claim 1, Park discloses a battery comprising: an electrode body including a positive electrode (cathode, col. 4 lines 66-67) and a negative electrode (anode, col. 4 lines 14-15) stacked with a separator provided therebetween (see col. 5 lines 24-25 which discloses that the anode, cathode and a polymer electrolyte/separator are laminated/stacked); an electrolyte (see col. 5 lines 41-53 which discloses an electrolytic solution injected into the battery); and an exterior material (such as the plastic case disclosed in col. 6 lines 66-67), wherein at least one of the electrolyte, the separator, or the exterior material includes a filler (see col. 5 lines 13-22 which discloses forming the polymer electrolyte/separator with a filler), and the filler includes a zeolite having no Si as a constituent element (see claim 1 of Park which discloses a filler which is a zeolite made of aluminophosphate, no silicon). 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) 3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Park (US 6,503,661). Regarding claim 3, Park does not teach the exact claimed range for pore size, but does teach that the filler/zeolite, or aluminophosphate, has a pore size of 0.5 to 1nm which overlaps the claimed range (see col. 3 lines 8-11). As such, arriving at the claimed range would have been obvious to one of ordinary skill in the art at the time of the invention. In the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists (see MPEP §2144.05(I)). Relevant Prior Art US 2018/0254531 – Discloses the use of zeolites in batteries for enhanced conductivity. US 2014/0023930 – Discloses adding an aluminum phosphate into a separator/electrolyte of an electrochemical device. US 2018/0043656 – Discloses the presence of aluminophosphate in the separator/electrolyte of a battery.
