Office Action

§102 §103
DETAILED ACTION This Office Action is responsive to the Applicant’s communication filed 17 June 2024. In view of this communication, claims 1-10 are pending in the application. 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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. 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) 1-6 and 8-9 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Olson (US 20110050381 A1), hereinafter referred to as Olson.

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) 7 and 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Olson in view of Morita et al. (US 20180374630 A1), hereinafter referred to as Morita et al. Regarding claim 7, Olson teaches the coil device according to claim 4, wherein the second main surface located in the first portion partially faces the second main surface in the second portion, in the state where the base film is folded (see Fig. 2), the second portion is spaced apart from the first portion in the state where the base film (110) is folded (see Fig. 2 and paragraph 37: spacer 280), but does not teach that the coil device further comprises an electronic component disposed between the first portion and the second portion in the state where the base film is folded, and connected to the second wire. Morita et al. does teach that the coil device further comprises an electronic component disposed between the first portion and the second portion in the state where the base film is folded, and connected to the second wire (Morita et al. Fig. 1 and paragraph 15: IC chip 24 disposed on the first surface of the board such that it would be between the first and second portion when folded). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide the coil device of Olson with an electronic component as taught by Morita et al. because providing control circuitry as taught by Morita et al. would increase the functionality of the coil device taught by Olson. Regarding claim 10, Olson teaches the coil device according to claim 8, but does not teach an electronic component disposed between the second portion and the third portion in the state where the base film is folded. Morita et al. does teach an electronic component disposed between the second portion and the third portion in the state where the base film is folded (Morita et al. Fig. 1 and paragraph 15: IC chip 24 disposed on the first surface of the board). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide the coil device of Olson with an electronic component as taught by Morita et al. because providing control circuitry as taught by Morita et al. would increase the functionality of the coil device taught by Olson.
