Office Action

§103
5/DETAILED ACTION Status of the Claims In the communication dated February 17, 2026, claims 1-20 are pending. Claims 1, 3, 10, 12 and 19 are currently amended. Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on February 17, 2026 has been entered. Response to Arguments Applicant’s arguments with respect to claims 1, 10 and 19 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. As detailed further below, the reference of Cheikh et al. US20210242720A1 is newly cited. Claim Objections Claims 1-20 are objected to because of the following informalities: Claim 1, line 7 “non-propogating” should amended to “non-propagating” to correct a typographical error. Claims 10 and 19 include similar language and thus are objected to for the same reasoning. Claims 2-9, 11-18 and 20 are objected to due to their dependency from an objected to claim. Appropriate correction is required. 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. Claims 1-2, 7-11 and 16-19 are rejected under 35 U.S.C. 103 as being unpatentable over Cheikh et al. US20210242720A1 in view of Wiemeersch et al. US20140253025A1.

It would be obvious to one of ordinary skill in the art at the time of invention to provide the control of Wiemeersch to the system of Cheikh, which includes the non-propagating magnetic field, in order to provide a customized charging to the particular device taking into account individual charging needs (Wiemeersch; ¶2 and 28).

Manico discloses the processor is configured to execute instructions to illustrate a charging zone on the display (¶106-107 – display is partitioned into a wirelessly charging device portion depending upon the location of the device). It would be obvious to one of ordinary skill in the art to provide the additional display features of Manico to the display of Wiemeersch in order to enable consumers to better interact with small scale devices without requiring proximity to a personal computer (Manico; ¶10). Regarding claim 15, Cheikh does not explicitly disclose illustrating a charging zone on a display of the charging surface. Manico discloses illustrating a charging zone on the display of the charging surface (¶106-107 – display is partitioned into a wirelessly charging device portion depending upon the location of the device).
