DETAILED ACTION
Claims 1-21 have been examined and are rejected.
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 .
Information Disclosure Statement
The information disclosure statement filed 01/31/2025 fails to comply with the provisions of 37 CFR 1.97, 1.98 and MPEP § 609 because Cite No 9 in the “NON-PATENT LITERATURE DOCUMENTS” section is listed as “HENRY J., et al., "Auto and Group Epochs", IEEE 802.11-24/0681r0-1, April 9, 2024, 25 Pages.”. However, it appears that there is no reference filed that has the titled “Auto and Group Epochs”. The only 25 page document filed appears to have the title “TGbi – Epoch Structure Proposal”, which is not the title listed (Cite No 9) on the IDS. Thus, Cite No 9 is not a proper identification of the reference and therefore, Cite No 9 is not being considered. It has been placed in the application file, but the information referred to therein has not been considered as to the merits. Applicant is advised that the date of any re-submission of any item of information contained in this information disclosure statement or the submission of any missing element(s) will be the date of submission for purposes of determining compliance with the requirements based on the time of filing the statement, including all certification requirements for statements under 37 CFR 1.97(e). See MPEP § 609.05(a).
Priority
The later-filed application must be an application for a patent for an invention which is also disclosed in the prior application (the parent or original nonprovisional application or provisional application). The disclosure of the invention in the parent application and in the later-filed application must be sufficient to comply with the requirements of 35 U.S.C. 112(a) or the first paragraph of pre-AIA 35 U.S.C. 112, except for the best mode requirement. See Transco Products, Inc. v. Performance Contracting, Inc., 38 F.3d 551, 32 USPQ2d 1077 (Fed. Cir. 1994).
The disclosure of the prior-filed application, Application No. 63/584,867, fails to provide adequate support or enablement in the manner provided by 35 U.S.C. 112(a) or pre-AIA 35 U.S.C. 112, first paragraph for one or more claims of this application. Claims 1, 8 and 15 recite “transmitting, by an access point, one or more wireless frames advertising support for Enhanced Data Privacy (EDP)”, “the wireless action frame requests a second epoch including a second epoch time interval different from the first epoch time interval”, and “transmitting, by the access point, a responsive wireless action frame accepting the second epoch”. These features are missing from Application No. 63/584,867. Therefore, there is no support for the above features in Application No. 63/584,867 filed on 09/23/2023.
Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission.

Claims 1, 8 and 15 provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 6 and 11 of copending Application No. 19/043,388 in view of Henry et al. (U.S. PGPub 2022/0377042). See the table below.
This is a provisional nonstatutory double patenting rejection.
Application No. 19/012,511
Copending Application No. 19/043,388
Claims 1, 8 and 15. A method comprising transmitting, by an access point, one or more wireless frames advertising support for Enhanced Data Privacy (EDP), wherein the one or more wireless frames indicate support for group-based EDP;
transmitting, by the access point, one or more epoch parameters associated with a first group epoch, wherein a first epoch parameter of the one or more epoch parameters comprises a first epoch time interval; receiving, by the access point, a wireless action frame transmitted by the wireless station, wherein the wireless action frame requests a second epoch including a second epoch time interval different from the first epoch time interval;
transmitting, by the access point, a responsive wireless action frame accepting the second epoch; and
maintaining a wireless connection with the wireless station using a plurality of Over-The-Air (OTA) Media Access Control (MAC) addresses for the wireless station that are rotated at the second epoch interval.
Claims 1, 6 and 11. A method comprising: transmitting, by an access point, one or more wireless frames advertising support for enhanced data privacy (EDP), wherein the one or more wireless frames indicate support for group-based EDP;

transmitting, by the access point, one or more epoch parameters associated with a plurality of epoch groups, wherein a first epoch parameter of the one or more epoch parameters comprises epoch timing information and a second epoch parameter indicates a number of wireless stations participating in the corresponding epoch group; receiving, by the access point, a wireless action frame transmitted by the wireless station, wherein the wireless action frame indicates a first epoch group of the plurality of epoch groups that the wireless station proposes to join; and
maintaining a wireless connection with the wireless station using a plurality of over-the-air (OTA) medium access control (MAC) addresses for the wireless station that are rotated at an epoch interval associated with the first epoch group.
However, Copending Application No. 19/043,388 does not explicitly teach transmitting, by the access point, a responsive wireless action frame accepting the second epoch; and
Henry teaches transmitting, by the access point, a responsive wireless action frame accepting the second epoch; and (Henry, see figs. 3-5; see paragraph 0059 where the AP 104 can accept the authentication/association/reassociation of the STA 112-1, as shown at 414a and communication link for the STA 112-1 may be maintained…; see paragraph 0061 AP 104 determines at 416 that the MAC address rotation of the STA 112-1 should be performed... AP 104 transmits an unsolicited Robust Action frame to STA 112-1 that is an RCM management request frame, which, in the context the example of FIG. 4 is considered an unsolicited RCM management request frame that includes a rotation status indicator indicating “rotation recommended” and timing information including a delay timer set to “0” to indicate that STA 112-1 may immediately perform a MAC address rotation...)
It would have been obvious to one of ordinary skill in the art, at the time the invention was filed, to combine Copending Application No. 19/043,388 and Henry to provide the technique of transmitting, by the access point, a responsive wireless action frame accepting the second epoch of Henry in the system of Copending Application No. 19/043,388 in order to improve privacy of a wireless device user (Henry, see paragraph 0003).

2. The method of claim 1, further comprising transmitting, by the access point, a responsive wireless action frame to the wireless station, the responsive wireless action frame indicating acceptance of the wireless station into the first epoch group.
maintaining a wireless connection with the wireless station using a plurality of over-the-air (OTA) medium access control (MAC) addresses for the wireless station that are rotated at an epoch interval associated with the first epoch group.
Regarding claims 3, 5, 10, 12, 17 and 19, claims 3, 5, 10, 12, 17 and 19 of Application No. 19/012,511 correspond respectively to claims 8, 10, 8, 10, 18 and 20 of Copending Application No. 18/999,608.
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 1-21 are rejected under 35 U.S.C. 103 as being unpatentable over Ansley et al. (U.S. PGPub 2024/0291797) in view of Henry et al. (U.S. PGPub 2022/0377042).
Regarding claims 1, 8 and 15, Ansley teaches A method comprising transmitting, by an access point, one or more wireless frames advertising support for Enhanced Data Privacy (EDP), wherein the one or more wireless frames indicate support for group-based EDP; (Ansley, see figs. 2 and 3; see abstract where access point receives an indication from the station that the station supports media access control address during association…; see paragraph 0026 include a STA indicating to other STAs that it can support a MAC address change while associated by setting a field that could be named the Enhanced Data Privacy (EDP) Active to 1. This field may be added to the Extended Capabilities field and communicated in one of the beacon frames, the Probe request/response frames, and other frames...; see paragraph 0024 update groups of STAs. When an AP notifies a group of STAs of the upcoming changes, the AP may use a Block Acknowledgement (BA) to receive acknowledgements from the STAs in the group to ensure that all of them are ready.)

An AP may provide a seed for each STA to use separately to reset PHY parameters...the AP may set the transition timer for the MAC changes to happen after the STA has had time to wake up and receive the information about the upcoming MAC changes. Alternatively, the AP may coordinate a selected group of STAs to change, then wait to notify another set of STAs to change.; see paragraph 0047 indicate to the AP (that is, first AP 120) that it supports the MAC address change or rotation while being associated. The STA may also indicate other parameters associated with the MAC address change, such as a preference for an interval between changes, a preferred MAC address space, or other related parameters.)
receiving, by the access point, a wireless action frame transmitted by the wireless station, (Ansley, see figs. 2 and 3; see paragraph 0048 the station (that is, first client device 135) may also initiate the MAC change. Alternatively, the AP may send an Action frame to the STA or STA targeted for MAC address change. In still other instantiations, the STA may send an Action frame to the AP requesting a MAC address change...)
However, Ansley does not explicitly teach wherein the wireless action frame requests a second epoch including a second epoch time interval different from the first epoch time interval;
