Office Action

§101 §112
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 . Response to Amendment The following is a final office action in response to applicant’s reply, filed on 06/04/2026, to the Non-Final Office Action mailed on 12/04/2025. Claims 1, 12 and 14 are amended. Claims 16-19 are added. Claim 15 is canceled. Claims 1-14, 16-19 are pending and addressed below. Applicant’s amendment has overcome objection to the drawing and rejection under 101 and 112(b), previously set forth in the non-final office action. Claim Rejections - 35 USC § 112 Claims 1-14, 16-19 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. Independent Claims 1 and 12 amendment “based on weighing factors of the current context” lacks clarity. It is not clear about the characteristics of the weighing factors of a context, and what it represents or is based on. It is also unclear about plurality of “weighing factors” for a single context. Specification e.g., para [146] of the published application where expression “weighting” is solely disclosed, does not provide any clarity of the above-mentioned issues on the weighing factor. The claim is therefore indefinite. Claims 2-11, 13-14, 16-19 are subject to the same rejection, because of their dependency on the rejected claims 1 and 12 above. Response to Arguments Applicant’s arguments with respect to claim 1 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. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. NAM; US 20250203516 A1 - AIR-INTERFACE-BASED ENVIRONMENT SENSING ASSISTED BY DEVICE-EQUIPPED TARGET OBJECT; para [127], Fig. 4B. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the date of this final action.
