Office Action

§103
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 . 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 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. Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 23 June 2026 has been entered. Response to Arguments Applicant's arguments filed 23 June 2026 have been fully considered but they are not persuasive. Applicant argues that neither Cha ‘452 nor Kitada discloses wherein the protective layer overlaps the plurality of first internal electrode and the plurality of second internal electrodes. The examiner agrees that Kitada and Cha ‘452 taken alone fail to disclose wherein the protective layer overlaps the plurality of first internal electrode and the plurality of second internal electrodes. However, the limitation is taught by the combination. Specifically Cha ‘452 discloses wherein the end part of the first internal electrode is overlapped by the second connection electrode and the end part of the second internal electrode is overlapped by the first connection electrode. Kitada discloses the protective layer extends along the first and second surface past the ends of the connection electrode and thus when the teachings of Kitada are applied to Cha ‘452 the limitation of wherein the protective layer overlaps the plurality of first internal electrode and the plurality of second internal electrodes is taught. All claims stand rejected. Claim Objections Claim(s) 1 & 14 is/are objected to because of the following informalities: In regards to claim 1 and 14, The recitation of “wherein the protective layer overlaps the plurality of first internal electrode and the plurality of second internal electrodes” should read “wherein the protective layer overlaps the plurality of first internal electrodes and the plurality of second internal electrodes” Appropriate correction is required. 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. Claim(s) 1, 3-11, 13-14, 16-18, & 21 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cha et al. (US 2020/0066452) in view of Kitada et al. (US 2016/0090661).

In regards to claim 13, Cha ‘452 as modified by Kitada ‘661 further discloses wherein: the protective layer includes glass including sodium (Na), copper (II) (Cu), and silicon (Si) (table 2-3 of Kitada ‘661). In regards to claim 14, Cha ‘452 discloses a multilayer ceramic capacitor, comprising: a ceramic main body (110 – fig. 4; [0076-0077]) including a first surface and a second surface facing each other in a first direction, a third surface and a fourth surface facing each other in a second direction and connecting the first surface and the second surface, and a fifth surface and a sixth surface facing each other in a third direction and connecting the first surface and the second surface (fig. 4; [0080]); an internal electrode (121/122 – fig. 4; [0077])) disposed inside the ceramic main body; wherein the internal electrode includes a plurality of internal electrodes disposed inside the ceramic main body (fig. 4), wherein the plurality of internal electrodes includes a plurality of first internal electrodes (121) that extend from the third surface of the ceramic main body, and a plurality of second internal electrodes (122) that extend from a fourth surface of the ceramic main body (fig. 4), and wherein adjacent internal electrodes among the plurality of internal electrodes are electrically insulated from each other (fig. 4), a connection electrode (131a/132a – fig. 4; [0111]) covering the third surface, wherein the connection electrode includes a portion in contact with at least one internal electrode (fig. 4). Cha ‘452 fails to disclose a protective layer disposed on a portion of the third surface and a portion of the fourth surface of the ceramic main body; and the connection electrode covering the protective layer, wherein the connection electrode includes the portion in contact with at least one internal electrode through a portion where the protective layer is not positioned on the third and fourth surfaces of the ceramic main body, wherein the protective layer comprises a portion that protrudes further than the connection electrode on the first and second surfaces of the ceramic main body, wherein the protective layer further comprises a portion extending onto the first surface and the second surface, wherein the portion of the protective layer extending to the first surface and the second surface extends continuously without an opening on the first surface and the second surface, wherein the protective layer overlaps the plurality of first internal electrode and the plurality of second internal electrodes. Kitada ‘661 discloses a ceramic main body (1 – fig. 1; [0057]) including a first surface and a second surface facing each other in a first direction, a third surface and a fourth surface facing each other in a second direction and connecting the first surface and the second surface, and a fifth surface and a sixth surface facing each other in a third direction and connecting the first surface and the second surface (fig. 1); an internal electrode (2 – fig. 1; [0057])) disposed inside the ceramic main body; wherein the internal electrode includes a plurality of internal electrodes disposed inside the ceramic main body (fig. 1), wherein the plurality of internal electrodes includes a plurality of first internal electrodes that extend from the third surface of the ceramic main body (fig. 1), and a protective layer (4 – fig. 1; [0059]) disposed on a portion of the third surface and a portion of the fourth surface of the ceramic main body; and a connection electrode (3 – fig. 1; [0058]) covering the protective layer, wherein the connection electrode includes a portion in contact with at least one internal electrode through a portion where the protective layer is not positioned on the third and fourth surfaces of the ceramic main body (fig. 1), wherein the protective layer comprises a portion (4a – fig. 1; [0060]) that protrudes further than the connection electrode on the first and second surfaces of the ceramic main body, wherein the protective layer further comprises a portion extending onto the first surface and the second surface (fig. 1), wherein the portion of the protective layer extending to the first surface and the second surface extends continuously without an opening on the first surface and the second surface (fig. 1), wherein the protective layer extends beyond the end points of connection electrode on the first surface and the second surface (fig. 1).
