Regarding claim 8, Haratani et al. disclose the thickness of the thin portion (@W) is about 20% or less of the thickness of the main facing portion (see Fig. 2 – portion close to edge of the thin portion). Claim Rejections - 35 USC § 103 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 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. Claim(s) 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hashimoto et al. (US 2020/0105468) in view of Takashima et al. (US 2015/0116898). Regarding claim 6, Hashimoto et al. disclose the claimed invention except for a continuity of the thin portion is lower than continuity of the main facing portion. Takashima et al. disclose a capacitor comprising internal electrodes (4), wherein the internal electrodes (4) comprise edge portions (9d1, 9d2) and a main facing portion (9c), wherein a continuity of the edge portion is lower than continuity [0136]-[0138] of the main facing portion. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the invention to form the device of Hashimoto et al. so that a continuity of the thin portion is lower than continuity of the main facing portion, since such a modification would form a multilayer ceramic capacitor where the occurrence of delamination is reduced or prevented. Claim(s) 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Haratani et al. (US 6,278,602) in view of Mizuno et al. (US 2007/0025055). Regarding claim 10, Haratani et al. disclose in the claimed invention except for the thin portion is curved toward the first main surface. Mizuno et al. disclose a multilayer ceramic capacitor comprising an internal electrode, wherein an end surface (13b) of the internal electrode is curved toward a first main surface (Fig. 3). It would have been obvious to a person of ordinary skill in the art before the effective filing date of the invention to form the multilayer ceramic capacitor of Haratani et al. so that the thin portion is curved toward the first main surface, since such a modification would prevent cracks due thermal stress. Claim(s) 14-18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hashimoto et al. (US 2020/0105468) in view of Yamaguchi et al. (US 2015/0155098). Regarding claim 14, Hashimoto et al. disclose the claimed invention except for the inner electrode includes a first metal component and a second metal component different from the first metal component and defining a solid solution layer. Yamaguchi et al. disclose a multilayer ceramic capacitor comprising internal electrodes (3, 4) wherein the internal electrodes contain Ni and Sn and have a solid solution of Sn and Ni [0043]. It would have been obvious to a person of ordinary skill in the internal electrode art before the effective filing date of the invention to form the multilayer ceramic capacitor of Hashimoto et al. so that the internal electrodes comprise a first metal component and a second metal component different from the first metal component and defining a solid solution layer, since such a modification would form a highly reliable ceramic capacitor with excellent high-temperature load life. Regarding claim 15, Yamaguchi et al. disclose the first metal component includes Ni [0043]. Regarding claim 16, Yamaguchi et al. disclose the second metal component includes Sn [0043], In, Ga, Zn, Bi, Pb, Fe, V, Y or Cu. Regarding claim 17, Yamaguchi et al. disclose the second metal component includes Sn [0043]. Regarding claim 18, Yamaguchi et al. disclose a thickness of the solid solution layer is about 1 nm or more and about 20 nm or less [0043]. Regarding claim 19, Yamaguchi et al. disclose the solid solution layer includes a central solid solution layer (claim 1, [0043]) and an outer solid solution layer (claim 1, [0043]); the second metal (Sn – claim 1, [0043]) component of the central solid solution layer includes a molar amount of about 0.008 or more and about 0.025 or less relative to a total molar amount of the first and second metal components (claim 1 – [0043]); and the second metal (Sn – claim 1, [0043]) component of the outer solid solution layer includes a molar amount of about 0.008 or more and about 0.025 or less relative to a total molar amount of first and second metal components (claim 1 – [0043]). Yamaguchi et al. do not disclose a specific example where the solid solution layer includes a central solid solution layer and an outer solid solution layer; the second metal component of the central solid solution layer includes a molar amount of about 0.008 or more and about 0.025 or less relative to a total molar amount of the first and second metal components; and the second metal component of the outer solid solution layer includes a molar amount of about 0.008 or more and about 0.025 or less relative to a total molar amount of first and second metal components. However, in the case where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990) Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
