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 Arguments
Regarding First Argument:
Applicant argues in substance that amended independent claims overcome provisional double patenting rejection of claims 1-9, 12-17, and 20-30.
Examiner has reviewed amended claim language as well as claim language of co-pending application 18/506,563 ad respectfully disagrees with applicant’s assertion. Both sets of claims are receiving a grant for low latency communication from a second wireless device, both transmit using the grant and both contain a third physical layer PPDU that preempts a second physical layer PPDU within the transmission opportunity. The wording of both sets of claims is mildly different, however when distilled down to the actual steps taken one of ordinary skill in the art would see them as patentably indistinct. As far as applicant’s argument that the rejection is improper, both applications are pending and the rejection is provisional and will be withdrawn when there is either a terminal disclaimer filed or the scope of the claims no longer overlap. At this point in time, given the claim language as currently written, the rejection is proper and is thus maintained.
Regarding Second Argument:
Applicant argues in substance that amended independent claims overcome previous 35 U.S.C 101 rejection of claims 20, 23-27, 27 and 30.
Examiner has reviewed amended independent claim language and agrees that the amendment has overcome previous 101 rejection. Rejection is hereby withdrawn.
Regarding Third Argument:
Applicant argues in substance that amended claims overcome previous prior art rejection.
Examiner respectfully disagrees. Applicant argues that SIFS is not an interframe space, this is not true. One of ordinary skill knows that SIFS is a short interframe space, while the cited prior art did not explicitly define the acronym, the term is common enough one of ordinary skill in the art would know the meaning. Furthermore, applicant argues that the SIFS is not being used to transmit data during a grant. When viewing at least figures 3-10 and associated description, instead of using a full-length inter frame space between frames the prior art is using a short inter frame space (SIFS) and transmitting in the time saved when compared to a full length inter frame space. This is evidenced by the cited portions of Chu found below.
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 1-9, 12-17, 20-30 provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-4, 7, 14-17, 20-22, 26-30 of copending Application No. 18/506,563 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the aspects of the claims in the copending reference application overlap in scope to the point where one of ordinary skill in the art would be able to describe the reference invention with the claim language of the provisionally rejected claims. Both sets of claims are receiving a grant for low latency communication from a second wireless device, both transmit using the grant and both contain a third physical layer PPDU that preempts a second physical layer PPDU within the transmission opportunity (interframe space). The wording of both sets of claims is mildly different, however when distilled down to the actual steps taken one of ordinary skill in the art would see them as patentably indistinct. At this point in time, given the claim language as currently written, the rejection is proper and is thus maintained. In other words, the above referenced claims within the instant application anticipate the above referenced claims in the reference application.
This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
Claim Rejections - 35 USC § 102
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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(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.
Claim(s) 1-30 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Chu (US 20240284496 A1) hereafter Chu.

Within a DL TXOP, the AP as the TXOP holder can preempt the TXOP by transmitting the low latency traffic frames to a STA other than the TXOP responder. One option is that this means the non-AP MLD that the TXOP responder is affiliated with will switch to listening operation on multiple links. Another option is that the TXOP responder will wait for the frame exchanges with it after AP's low latency traffic frame exchanges. In order to help such operation, in some embodiments, the PHY header indicates the frame exchange of the low latency traffic.

In some embodiments, within the preemptible DL TXOP, the AP as the TXOP holder can preempt the TXOP by transmitting the low latency traffic frames to the responder using a shorter inter-frame space (e.g., SIFS). In some embodiments, within the preemptible DL TXOP, the AP as the TXOP holder can preempt the TXOP by transmitting the low latency traffic frames to a STA other than the TXOP responder using a shorter inter-frame space (e.g., SIFS).)
Regarding Claim 11:

In some embodiments, within the preemptible DL TXOP, the AP as the TXOP holder can preempt the TXOP by transmitting the low latency traffic frames to the responder using a shorter inter-frame space (e.g., SIFS). In some embodiments, within the preemptible DL TXOP, the AP as the TXOP holder can preempt the TXOP by transmitting the low latency traffic frames to a STA other than the TXOP responder using a shorter inter-frame space (e.g., SIFS).

In some embodiments, the TXOP responder in EMLSR mode use SIFS+2*aSLotTime as inter-frame space to decide whether it needs to switch to listening operation in multiple links because of no frame addressed to it being received after the previous frame exchange, i.e., with SIFS+2*aSLotTime+aRxPHYStartDelay timeout where aRxPHYStartDelay is used to decoding the frame header.)
Regarding Claim 14:
