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 . Claims Status Claims 1-5, 7-9, 12-13 and 15-23 are currently pending, claims 1-5, 7-9, 12-13, 15-22 are currently amended and claim 23 is new. Response to Arguments/Amendments Applicant’s arguments, see remarks and amended claims, filed on 05/26/2026, with respect to the rejection(s) of amended claim(s) 1, 20, 21 and 22 under 35 U.S.C. 103 have been fully considered and are persuasive. Applicant’s amendments overcome the previous prior art rejection. However, the claims are now rejected in view of newly found prior art reference KARANIKOS et al. (US 2022/0094202 A1). Please see new grounds of rejection below which address the newly added limitations of ferrite backings positioned within recesses pockets. 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) 21 is/are rejected under 35 U.S.C. 103 as being unpatentable over NAHUM (US 2021/0218277 A1, hereinafter NAHUM) in view of MATSUMOTO (US 2019/0292093 A1, hereinafter MATSUMOTO) and in further view of KARANIKOS et al.

The examiner explains that by limiting loss and maximizing efficiency, the receiver is configured to receive a maximum amount of power from the primary transmitter coil). NAHUM, MORA, MATSUMOTO, KARANIKOS and GUANGPING are analogous art since they all deal with wireless charging.
