Office Action

§102 §103 §112
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 Election/Restrictions Claims 3-5, 8-10, 13-15, and 18-20 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected Species II-IV, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 11/10/2025. Applicant's election with traverse of Species I in the reply filed on 11/10/2025 is acknowledged. The traversal is on the ground(s) that the search and examination of the entire application could be made without serious burden. This is not found persuasive because 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). The Species I-IV are different in structure and there is a search and/or examination burden for the patentably distinct species where it is necessary to search for one of the species in a manner that is not likely to result in finding art pertinent to the other species. The requirement is still deemed proper and is therefore made FINAL. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 2 and 6-7 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 2 recites the terms “the second portion” and “the first portion” is indefinite and unclear which pad conductor it is corresponding to since claim 1 recited that each of the plurality of pad conductors includes a first portion and a second portion. As best understood, the examiner will interpret as one of the plurality of pad conductors for the second portion and the corresponding first portion. Claim 6 recites the terms “the third portion”, “the second portion” and “the first portion” is indefinite and unclear which pad conductor it is corresponding to since claim 1 recited that each of the plurality of pad conductors includes a first portion and a second portion and claim 6 recited that each of the plurality of pad conductors includes a third portion. As best understood, the examiner will interpret as one of the plurality of pad conductors for the third portion corresponding to the second portion and the corresponding first portion. Claim 7 recites “the third portion is formed to extend from the first portion in a direction in which a distance between the second portion and the coil does not decrease” is indefinite and unclear regarding the term “the second portion”. As best understood, the term “the second portion” should be --the third portion--. Claim 7 recites the terms “the third portion” and “the first portion” is indefinite and unclear which pad conductor it is corresponding to since claims 1 and 6 recited that each of the plurality of pad conductors includes a first portion and a third portion. As best understood, the examiner will interpret as one of the plurality of pad conductors for the third portion and the corresponding first portion. 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.

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) 1-2 and 6-7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Nishino et al. [U.S. Pub. No. 2016/0027578] in view of Takahashi [U.S. Pub. No. 2020/0281078]. Regarding Claim 1, Nishino et al. shows a multilayer coil component (Figs. 1-2A and Drawings 1-3 below) comprising: an element body (see Fig. 2A) including a main surface (top surface of element 10) arranged to constitute a mounting surface (top surface of element 10 can be used as a mounting surface, see Fig. 2A); a first external electrode (40B) and a second external electrode (40A) disposed on the main surface and separated from each other (see Fig. 1); a coil (elements 21-24 combined form a coil) disposed in the element body to have a coil axis along a direction intersecting the main surface (see Fig. 1), the coil including a first end (21B) and a second end (24B) separated from the main surface more than the first end (see Fig. 1, element 24B separated from top surface more than element 21B); a first connection conductor (40B) connecting the first external electrode and the first end (see Fig. 1); and a second connection conductor (53, 43, 52, 42, 51, 41) connecting the second external electrode and the second end (see Fig. 1), wherein the second connection conductor (53, 43, 52, 42, 51, 41) includes a plurality of pad conductors (53, 52, 51) and a plurality of through-hole conductors (43, 42, 41) that are alternately disposed in a direction crossing the main surface and separated from the coil (see Fig. 1), each of the plurality of through-hole conductors includes a connection end connected to an adjacent pad conductor among the plurality of pad conductors (see Fig. 1, each of elements 43, 42, 41 includes a connection end connected to an adjacent element 53, 52, 51), each of the plurality of pad conductors includes (see Drawings 1-3 below): a first portion (first portion P1, see Drawings 1-3 below) overlapping an entire connection end included in an adjacent through-hole conductor among the plurality of through-hole conductors (see Drawings 1-3 below, first portion P1 overlapping an entire connection end included in an adjacent element 43, 42, 41); and a second portion (second portion P2) that is continuous with the first portion and is separated from the coil more than the first portion (see Drawings 1-3 below, second portion P2 is continuous with first portion P1 and is separated from elements 21-24 more than first portion P1 shown as distance D1 and distance D2). In addition, Takahashi shows an element body (see Figs. 1A-2B) including a main surface (2) arranged to constitute a mounting surface (Paragraph [0078]). 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 an element body including a main surface arranged to constitute a mounting surface as taught by Takahashi for the coil component as disclosed by Nishino et al. to facilitate mounting to an external device such as a circuit board to achieve desirable operating characteristics (Paragraph [0020]). Regarding Claim 2 (see 112 rejection above), Nishino et al. shows the second portion is formed to extend from the first portion in a direction in which a distance between the second portion and the coil does not decrease (see Drawings 1, 2, and/or 3 below, second portion P2 is formed to extend from first portion P1 in a direction in which a distance such as distance D2 between second portion P2 and elements 21-24 does not decrease). Regarding Claim 6 (see 112 rejection above), Nishino et al. shows each of the plurality of pad conductors further includes a third portion (third portion P3, see Drawings 1, 2, and/or 3 below) that is separated from the second portion (see Drawings 1, 2, and/or 3 below), and the third portion is continuous with the first portion and is separated from the coil more than the first portion (see Drawings 1, 2, and/or 3 below, third portion P3 is continuous with first portion P1 and is separated from elements 21-24 more than first portion P1 shown as distance D1 and distance D3). Regarding Claim 7 (see 112 rejection above), Nishino et al. shows the third portion is formed to extend from the first portion in a direction in which a distance between the second/third portion and the coil does not decrease (see 112 rejection above, see Drawings 1, 2, and/or 3 below, third portion P3 is formed to extend from first portion P1 in a direction in which a distance such as distance D2 or distance D3 between second portion P2 or third portion D3 and elements 21-24 does not decrease).
