DETAILED ACTION
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 (IDS) submitted on 11/19/2024, 10/30/2025, and 07/23/2026; the submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner.
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.

An apparatus for wireless communication at a wireless communication device, comprising: means for modulating a physical layer convergence protocol (PLCP) protocol data unit (PPDU) on a number (M) of tones representing a logical resource unit (RU) that is associated with a number (K) of pilot tones each having a respective location relative to the M tones; means for mapping the M tones to M noncontiguous subcarrier indices of a plurality of subcarrier indices spanning a wireless channel, the M noncontiguous subcarrier indices representing a distributed resource unit (dRU); and means for transmitting, over the wireless channel, the PPDU including a number (N) of pilot tones each having a respective location relative to the M tones as mapped to the M noncontiguous subcarrier indices and different than the relative locations of the K pilot tones, the relative locations of the N pilot tones being associated with N subcarrier indices of the plurality of subcarrier indices and based at least in part on a hierarchical structure of the dRU.
2. (Previously Presented) A wireless communication device comprising: at least one processor; and at least one memory communicatively coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor, is configured to: modulate a physical layer convergence protocol (PLCP) protocol data unit (PPDU) on a number (M) of tones representing a logical resource unit (RU) that is associated with a number (K) of pilot tones each having a respective location relative to the M tones; map the M tones to M noncontiguous subcarrier indices of a plurality of subcarrier indices spanning a wireless channel, the M tones mapped to the M noncontiguous subcarrier indices representing a distributed resource unit (dRU), wherein the dRU is associated with a 26-tone dRU-based hierarchical structure; and transmit, over the wireless channel, the PPDU including a number (N) of pilot tones each having a respective location relative to the M tones as mapped to the M noncontiguous subcarrier indices and different than the relative locations of the K pilot tones, the relative locations of the N pilot tones being associated with N subcarrier indices of the plurality of subcarrier indices and based at least in part on the 26-tone dRU-based hierarchical structure in view of US-20210400670-A1 to HU.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. See PTO form PTO-892: US-20220279562-A1 to Park discloses mapping of tones both data and pilot also demapping process; US-20170288838-A1 to Cariou discloses PPDU resource allocation; US-20210273757-A1 to Shellhammer PLCP protocol data unit PPDU.
