This Office Action is in response to communication filed on 03/26/2026. Claims 1-5, 8-16 and 18-20, are pending and rejected. Claims 6, 7 and 17 are objected. Allowable Subject Matter Claims 6, 7 and 17 are 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. 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. Claims 1-4, 11, 13-15 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al (US 20200029276 A1) (hereinafter “Kim”) in view of Cariou et al (US 20230292245 A1) (hereinafter “Cariou”).

The motivation to combine both references would come from improvement of data rate and lower overhead. Xia fails to disclose but Cariou teaches reject request and transmit packets with the power management (PM) bit indicating that the low power Wi-Fi device is in the active mode if the low power Wi- Fi device has occasional data associated with the TIDs (see para. [0100]-[0101] discloses the device may set up a traffic identifier (TID) associated with data traffic to be exchanged with the non-AP MLD, wherein the setting up of the TID comprises mapping a plurality of TIDs to one or more enabled links of the plurality links. The TID comprises a TID mapping update comprising an indication a change of an initial power state of the first STA); block 406, the device may determine, based on the request frame, a power save mode associated with each of the STAs of the non-AP MLD. The power save mode may comprise an active state or a doze state based on a power management bit set 1 in the request frame). Xia and Cariou are considered analogous to the claimed invention because are in the same field of wireless communication systems. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filling date of the claimed invention to have a motivation to modify Xia to include the aggregation and TID as described by Cariou. The motivation to combine both references would come to maintain quality and reliability on the wireless link. Response to Arguments Applicant’s arguments, see pages 9-12, filed on 03/26/2026, with respect to the rejection of claims 1 and 13 under 35 U.S.C. 102 and the amended to recite “modifying the operation of the low power Wi-Fi device comprises transmitting packets from the low power Wi-Fi device with the power management (PM) bit set to a value indicating that the low power Wi-Fi device is in an active mode” have been fully considered. However, a rejection under 35 U.S.C. 103 under Cariou is provided for the amended claim. Under the broadest reasonable interpretation, claims 1 and 13 are still broad and do not disclose all elements in the specification regarding the behavior of the access point. The rejection is maintained. Applicant’s arguments, see pages 12-13, filed on 03/26/2026, with respect to the rejection of claim 20 under 35 U.S.C. 102 regarding “the selection of which mode is used is bases on the observed behavior of the access point” have been fully considered. However, examiner respectfully disagrees. Under the broadest reasonable interpretation, claims 20 still broad and do not disclose all elements in the specification regarding the behavior of the access point. The behavior for transmitting PS-Poll may be associated with the existence of not of buffered data (change on behavior on the AP). The rejection is maintained. 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.
