Office Action

§102 §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 . 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1, 5-6, and 10 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Shimoda et al. [U.S. Pub. No. 2019/0051450].

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. Claim(s) 5-9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tseng et al. in view of Aoki et al. [U.S. Pub. No. 2018/0342341]. Regarding Claim 5, Tseng et al. shows the claimed invention as applied above. In addition, Aoki et al. shows the terminal electrode (left element 3) has a second electrode part (left element 31) extending in the second direction (D2) orthogonal to the second surface (2a) along the first surface (2c), and exhibits an L-shape when seen in the third direction (D1, see Figs. 1-4, Paragraph [0032]). Before the effective filing date of the claimed invention, it would have been obvious to a person of ordinary skill in the art to have the terminal electrode has a second electrode part extending in the second direction orthogonal to the second surface along the first surface, and exhibits an L-shape when seen in the third direction as taught by Aoki et al. for the coil component as disclosed by Tseng et al. to facilitate electrical connection with increase stability and reliability. Regarding Claim 6, Tseng et al. shows the claimed invention as applied above but does not show at least a portion of the second electrode part of the terminal electrode is disposed inside the element assembly, and wherein an end of the second electrode part is provided with a recess portion. Aoki et al. shows at least a portion of the second electrode part (left element 31) of the terminal electrode (left element 3) is disposed inside the element assembly (see Figs. 1-4), and wherein an end (top end) of the second electrode part (left element 31) is provided with a recess portion (left or right element 21). Before the effective filing date of the claimed invention, it would have been obvious to a person of ordinary skill in the art to have at least a portion of the second electrode part of the terminal electrode is disposed inside the element assembly, and wherein an end of the second electrode part is provided with a recess portion as taught by Aoki et al. for the coil component as disclosed by Tseng et al. to suppress separation of the conductor to improve adhesion between the conductors and the element body (Paragraph [0008]-[0009]). Regarding Claim 7, Aoki et al. shows the recess portion (left or right element 21) of the second electrode part (left element 31) is formed without the first surface (2c, see Figs. 1-4).

Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
