Office Action

§DP
DETAILED ACTION Notice of Pre-AIA or AIA Status 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Objections 2. Claims 3, 11-13, 15 and 16 are objected to because of the following informalities: Claims 3, depending on claim 2, recites ‘the computer-readable recording medium…..’ instead of ‘the non-transitory machine-readable recording medium……’. Appropriate correction is required. Claims 11-13, 15 and 16 recite this underlined acronym ‘AP’ that needs to be written in full. Double Patenting 3. 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. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. 4. Claims 1-17 are rejected on the ground of nonstatutory double patenting as being unpatentable over Claims 1-17 of Patent No.: US 12,160,378 B2 to Guo, Yuchen. Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claims limitation are transparently found in the claims of the above mentioned patented claims. Applicant’s incorporate underlined limitations to the independent claims of this instant application below so as broaden the patented application. Thus, both set of claims are obvious variant of each other. See table and claim mapping below: Applicant’s merely broadens the independent claims of this instant application by adding some limitations to arrive at the limitations of the instant claims. Thus, both set of claims are obvious variant of each other. See table and claim mapping below: Patent No.: US 12,160,378 B2 Instant Application 18/926,942 Claim 1: A spatial reuse method, comprising: receiving, by a second access point (AP), a radio frame sent by a first AP, wherein the radio frame comprises identification information and a spatial reuse parameter (SRP) used by the second AP to determine a transmit power of a downlink frame; determining, by the second AP based on the identification information and the SRP, that the first AP configures a spatial reuse opportunity for the second AP to perform data transmission; and sending, by the second AP, a downlink frame to at least one second station (STA) associated with the second AP during an uplink data transmission performed by at least one first STA associated with the first AP.

Claim 8: A spatial reuse method, comprising: generating, by a first access point (AP), a radio frame that comprises identification information and a spatial reuse parameter (SRP) used by a second AP to determine a transmit power of a downlink frame, wherein the identification information configures a spatial reuse transmission opportunity for the second AP to perform data transmission, and enables the second AP to send a downlink frame to at least one second station (STA) associated with the second AP during an uplink data transmission performed by at least one first station associated with the first AP; and sending, by the first AP, the radio frame to the second AP. Claim 8: A non-transitory machine-readable recording medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising: generating a radio frame that comprises identification information and a spatial reuse parameter (SRP) used by the second access point (AP) to determine a transmit power of a downlink frame, wherein the identification information configures a spatial reuse transmission opportunity for a second AP to perform data transmission, and enables the second AP to send a downlink frame to at least one second station (STA) associated with the second AP during an uplink data transmission performed by at least one first station associated with the first AP; and sending the radio frame to the second AP.
