CTNF 18/841,236 CTNF 83277 Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Information Disclosure Statement The information disclosure statements (IDS) submitted on 1 st October 2025 and 4 th February 2026 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. ========== ========== ========== Claim Rejections - 35 USC § 102 07-12-aia AIA (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. 07-15-03-aia AIA Claim s 1 – 5 and 9 – 13 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Haider et al (US 2023/0180127 A1) . Claim 13 (similarly Claim 1 ). Haider shows a station (STA) device in a wireless local area network (WLAN) system (figs. 1 and 7: computing device 110 / client device 750 ), the STA device comprising: at least one transceiver (fig. 1: link 102B ; [0072]: an antenna may be attached to transceiver housing and electrically coupled to the transceiver ); and at least one processor connected to the at least one transceiver (fig. 1: processor 118 ), wherein the at least one processor is configured to: establish an agreement related to a restricted target wake time (R-TWT) ([0034]: if the station device supports the RSTP capability (station device’s RSTP Support field is set to 1), then the access point may allow communication with the station device, but may cause or instruct (or be in agreement with ) the station device to end its communication before the start of the service period allocated or reserved for the another device, according to access rules for R-TWT operation ); and transmit, through the at least one transceiver, a frame including a TWT information field to at least one another STA ([0090]: the broadcast TWT parameter set field may include the fields of target wake time, nominal minimum TWT wake duration, broadcast TWT information wherein the field of broadcast TWT information may include the two bits as a subfield of restricted TWT schedule information ), wherein based on a value of an all TWT subfield of the TWT information field being set as 1 ([0093]: the value “1” of the restricted TWT schedule information subfield ), and a TWT flow identifier subfield of the TWT information field being set as a specific value ([0095]: the first device may identify/detect/monitor an identifier of the OBSS, e.g. a BSSID, associated with the advertised TWT schedule ), a next TWT subfield of the TWT information field indicates rescheduling-related information for a R-TWT service period (SP) corresponding to the specific value (figs. 5 and 6: parameter set 520 ; [0110] – [0111]: scheduling information subfield with “0,” “1” and “2” specific values ). Claim 2. Haider shows the method of claim 1, wherein: the rescheduling-related information includes at least one of a suspension ([0117]: the R-TWT schedule may not be active if membership of the R-TWT schedule is suspended ), a resume timing reference ([0061]: the communication interfaces to resume communication based on stored information indicating communication between the computing device and the HWD ), or an extended end timing ([0061]: bypassing the scan procedure allows extension of a duration of the communication interfaces operating in the sleep mode, such that the computing device and the HWD can reduce power consumption ). Claim 3. Haider shows the method of claim 1, wherein: the specific value of the TWT flow identifier subfield is associated with an existing R-TWT SP ([0119]: the R-TWT schedule set up by the AP 710 may be indicated as “full” if the AP (or the duration manager) is unlikely to (or cannot) accept a request from an existing member of the R-TWT schedule to increase a schedule duration ) or a rescheduled R-TWT SP (figs. 5 and 6: parameter set 520 ; [0110] – [0111]: scheduling information subfield with “0,” “1” and “2” specific values ). Claim 4. Haider shows the method of claim 1, wherein: the specific value of the TWT flow identifier subfield is associated with a first type or a second type of an R-TWT SP ([0073]: the processor unit can be configured to determine a type of frame and to process the frame and/or fields of the frame accordingly ), a type of the R-TWT SP includes the first type for a transmission or reception in an uplink or downlink between a non-access point (non-AP) STA and an AP STA ([0085]: a device (e.g. AP or non-AP device (STA)) may advertise R-TWT schedules by indicating whether the device can accept new membership for STA(s) to join a particular R-TWT schedule ), and the second type for a peer-to-peer (P2P) transmission or reception between the non-AP STA and the non-AP STA ([0067]: the communication link between the computing devices and the HWDs may be a P2P link (e.g. a link used for transmission between two non-AP devices ) ; [0068]: the scheduler of the computing device(s) may also indicate if the SP(s) are requested only for P2P communication ). Claim 5. Haider shows the method of claim 1, wherein: the specific value of the TWT flow identifier subfield is associated with a suspension ([0117]: the R-TWT schedule may not be active if membership of the R- TWT schedule is suspended ) or an extension of an existing R-TWT SP ([0061]: bypassing the scan procedure allows extension of a duration of the communication interfaces operating in the sleep mode, such that the computing device ). Claim 9. Haider shows the method of claim 1, wherein: the STA is an R-TWT scheduled non-AP STA, the at least one another STA is an AP STA ([0085]: a device (e.g. AP or non-AP device (STA)) may advertise R-TWT schedules by indicating whether the device can accept new membership for STA(s) to join a particular R-TWT schedule ). Claim 10. Haider shows the method of claim 9, wherein the method further includes: before transmitting the frame including the TWT information field, receiving, from the AP STA, a management frame including first R-TWT SP allocation information based on the agreement related to the R-TWT ([0067]: the HWD may be considered the TWT requesting STA (e.g. the TWT STA that requests the TWT agreement ), and the computing device may be considered TWT responding STA (e.g. the TWT STA that respond to the TWT request) ; [0113]: the advertisement frame may be a beacon frame or other management frame such as probe request/response, association/disassociation, etc.) ); and after transmitting the frame including the TWT information field, receiving, from the AP STA, a management frame including rescheduled second R-TWT SP allocation information ([0113]: the duration manager may be configured to receive a request from a STA (e.g. client device) to increase a schedule duration (e.g. an SP duration or a nominal minimum TWT wake duration) of a particular R-TWT schedule, determine whether the request is accepted or rejected/denied, and if accepted, increase the schedule duration of the particular R-TWT schedule ). Claim 11. Haider shows the method of claim 1, wherein: the STA is a R-TWT scheduling AP STA, the at least one another STA is at least one non-AP STA ([0085]: a device (e.g. AP or non-AP device (STA)) may advertise R-TWT schedules by indicating whether the device can accept new membership for STA(s) to join a particular R-TWT schedule ). Claim 12. Haider shows the method of claim 11, wherein the method further includes: before transmitting the frame including the TWT information field, transmitting, to the at least one non-STA, a management frame including first R-TWT SP allocation information based on the agreement related to the R-TWT ([0067]: the HWD may be considered the TWT requesting STA (e.g. the TWT STA that requests the TWT agreement ), and the computing device may be considered TWT responding STA (e.g. the TWT STA that respond to the TWT request) ; [0113]: the advertisement frame may be a beacon frame or other management frame such as probe request/response, association/disassociation, etc.) ); and after transmitting the frame including the TWT information field, transmitting, to the at least one non-STA, a management frame including rescheduled second R-TWT SP allocation information ([0113]: the duration manager may be configured to receive a request from a STA (e.g. client device) to increase a schedule duration (e.g. an SP duration or a nominal minimum TWT wake duration) of a particular R-TWT schedule, determine whether the request is accepted or rejected/denied, and if accepted, increase the schedule duration of the particular R-TWT schedule ). ========== ========== ========== Allowable Subject Matter 12-151-08 AIA 07-43 12-51-08 Claim s 6, 7 and 8 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. ---------- ---------- ---------- Conclusion The prior art made of record is considered pertinent to applicant’s disclosure. 1. Xin et al, US 2023/0058871 A1: new data structures and processes are performed in which a station (STA) can request scheduling reserving target wait time (R-TWT) for the traffic transmission of a stream classification service (SCS) during the setup procedure of that SCS wherein, a STA can exchange a target wait time (TWT) setup frame on one link to schedule R-TWT on multiple links.
