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 . Election/Restrictions Claims 5-8 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected Group I, Species II and Group II, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 03/27/2026. Applicant's election with traverse of Group I, Species I in the reply filed on 03/27/2026 is acknowledged. The traversal is on the ground(s) that a thorough search for the subject matter of any one Group of claims or species would encompass a search for the subject matter of the remaining claims and species. This is not found persuasive because the inventions of Group I and Group II require a different field of search such as searching different classifications since Group II is a method of manufacturing a coil component. In addition, the species of patentably indistinct species require a different field of search (for example, searching different classifications, classes/subclasses or electronic resources, or employing different search queries). Species I is a specific design that is not found in other Species. The requirement is still deemed proper and is therefore made FINAL. 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. Claim(s) 1-3 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Tanaka et al. [JP 2012-195399]. Regarding Claim 1, Tanaka et al. shows a coil component (Figs. 1-8) comprising: a coil (22) configured of a winding (see Figs. 1-8); an exterior body (21) provided to cover the coil (see Figs. 1-8); and a terminal part (elements 27, 26 combined) configured to be continuous with the winding (see Figs. 1-8, Paragraph [0062]), wherein a proximal end portion (26) of the terminal part is buried in the exterior body (see Figs. 1-8), and a distal end portion (27) ahead of the proximal end portion is bent from the proximal end portion (see Figs. 1-8, element 27 ahead of element 26 is bent from element 26) and located outside a surface (right surface, see Fig. 2) of the exterior body along the surface (see Figs. 1-8, element 27 located outside of a right surface of element 21 along the right surface). Regarding Claim 2, Tanaka et al. shows the terminal part has a flat shape with a thickness smaller than a diameter of the winding (see Figs. 1-5, element 27 has a flat shape with a thickness smaller than a diameter of element 22, Paragraphs [0016], [0020], [0025], [0030]); and the proximal end portion has a flared shape of which a width gradually widens toward the distal end portion (see Fig. 5, element 26 has a flared shape of which a width gradually widens toward element 27). Regarding Claim 3, Tanaka et al. shows the distal end portion (27) protrudes more than the coil (22) in an extending direction (up-down direction or y-direction, see Fig. 2) of a central axis of the coil (see Fig. 2, element 27 protrudes more than element 22 in up-down direction or y-direction of a central axis of element 22). 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) 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tanaka et al. in view of Kakizaki et al. [U.S. Pub. No. 2021/0193374]. Regarding Claim 2, Tanaka et al. shows the terminal part has a flat shape with a thickness smaller than a diameter of the winding (see Figs. 1-5, element 27 has a flat shape with a thickness smaller than a diameter of element 22, Paragraphs [0016], [0020], [0025], [0030]); and the proximal end portion has a flared shape of which a width gradually widens toward the distal end portion (see Fig. 5, element 26 has a flared shape of which a width gradually widens toward element 27). In addition, Kakizaki et al. shows (Fig. 3B) the proximal end portion (12a) has a flared shape of which a width gradually widens toward the distal end portion (see Fig. 3B, Paragraph [0047]). 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 proximal end portion has a flared shape of which a width gradually widens toward the distal end portion as taught by Kakizaki et al. for the coil component as disclosed by Tanaka et al. to have mounting area, improves mounting strength, and improves reliability of electrical connection (Paragraph [0070]).
