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.

[0062]; [0066] discloses AP can use a CF-End frame to terminate the Quiet interval if the restricted TWT SP terminates earlier that the SP end time; AP transmits individual addressed frame to STA with EOSP (End of Service Period) field set to 1),

Allowable Subject Matter
Claim 11 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Response to Arguments
Applicant’s argument, see page 10, filed on 03/03/2026 with respect of drawings have been considered by the examiner. The drawings were received on 11/01/2023. These drawings are accepted.
Applicant’s arguments, see pages 11-12, filed on 03/032026 with respect to the rejection of claim 2 under 35 U.S.C. 103 have been fully considered by examiner. Applicant argues that Kim fails to disclose or suggest “receiving, by the first STA from the AP, information related to a modified end time of the r-TWT SP” and “information related to the modified end time of the r-TWT is provided from the AP”. Examiner disagrees. Kim discloses as applicant indicates that AP trigger frame does not provide any information related to the extended SP because is already determined by the STA, however the trigger frame is implicitly providing the information to the STA. In order to clarify this point, new ground of rejection is made in view of Shafi et al (US 20220361194 A1).
Conclusion
THIS ACTION IS MADE FINAL. 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.
