Claim Rejections - 35 USC § 103 07-06 AIA 15-10-15 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. 07-20-aia AIA 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. 07-23-aia AIA 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. 07-20-02-aia AIA 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. 07-21-aia AIA Claims 1-19 are rejected und er 35 U.S.C . 103 as being unpatentable over Ku (US 2021/0242490), and alternatively in view of Uematsu (US 2024/0097132). As to claim 1, Ku disclo ses a positive electrode-solid electrolyte subassembly (figures 11-13 #30 and 10, [0121], discussed throughout) comprising: a positive electrode (figures 11-13, #10, [0121]) comprising a positive electrode active material (figures 11-13 #12, [0160]-[0162]), a conductive material ([0169], conductive material), and a first solid electrolyte ([0162], solid electrolyte; the solid electrolyte within the cathode is the first solid electrolyte); a second solid electrolyte disposed on the positive electrode (figures 11-13 #31, [0147]); and an interlayer disposed between the positive electrode and the second solid electrolyte (figures 11-13 #32, [0147]), wherein the interlayer comprises an interlayer material ([0147]-[0154], solid electrolyte), the interlayer material having an electrical conductivity less than an electrical conductivity of the conductive material of the positive electrode ([0169], shows the conductive additives within the positive electrode, the carbon conductive additives have a higher electrical conductivity then the solid electrolyte disclosed [0147]-[0154], i.e. acetylene black compared to lithium chloride ), and wherein the first solid electrolyte comprises lithium and a metal, and a sulfur-free lithium-ion conductor ([0148]-[0154], note Ku discloses or combinations thereof, thus the lithium and metal can be picked and then formula 6 without sulfur can be picked). It would have been obvious to one of ordinary skill within the art at the time of the effective filling date of the invention to use the materials from Ku in combination with one another as a mere combing prior art elements according to known methods to obtain predictable results. Should it Ku is silent to wherein, the first solid electrolyte comprising a lithium metal or a sulfur free lithium-ion conductor. Uemastu discloses an electrode wherein the electrode comprises an active material and a solid electrolyte particle wherein the solid electrolyte particle comprises lithium, a metal and is sulfur free ([0004]), wherein the electrode further comprises a conductive material ([0114]-[0122]) and wherein the electrode is a positive electrode ([0045]-[0049]). It would have been obvious to one of ordinary skill within the art at the time of the effective filling date of the invention to use the positive electrode from Uemastu within Ku because the electrode improves the batteries input output characteristics ([0003]-[0006], Uemastu). As to claim 2, modified Ku discloses wherein, the sulfur-free lithium-ion conductor has a sulfur content of less than 1 mole percent, based on a total content of the sulfur-free lithium-ion conductor ([0149]-[0154], formula 6 wherein sulfur is not used; [0004], Uemastu). As to claim 3, modified Ku discloses wherein, the interlayer material has an electrical conductivity of less than 1 Siemens per meter ([0148]-[0154], the Li 2 S-P 2 S 5 - are a few examples of the electrolytes that meet the claimed limitation, [0065]-[0068]).
