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).

Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Seok et al. (US 2016/0044533 A1), Figs 6-7, paragraph 0082 disclose a reception apparatus for receiving a PPDU frame from a transmission apparatus in a WLAN may be provided. The reception apparatus may include a baseband processor, an RF transceiver, a memory. The baseband processor may be configured to receive a first region including a legacy preamble and a first field in a PPDU frame using the RF transceiver, and to receive a second region including a HE-preamble in the PPDU frame based on information included in the first region using the RF transceiver.
Yang et al. (US 2020/0228380 A1) Paragraphs 0043-0044, Fig. 2B disclose the PPDU includes a legacy-short training field (L-STF), a legacy-long training field (L-LTF), a legacy-signal (L-SIG), a repeated legacy-signal (RL-SIG), a universal-signal (U-SIG), an extremely high throughput-signal (EHT-SIG), an EHT-STF, an EHT-LTF and a data field.
Park et al. (US 2020/0136884 A1), Paragraph 0115 discloses a PPDU 2100 with a universal signal field (U-SIG), in accordance with some embodiments. Illustrated in FIG. 21 is PPDU 2100, which includes one or more of L-STF 2102, L-LTF 2104, L-SIG 2106, RL-SIG 2108, U-SIG 2110, version dependent (VD) SIG 2112, VD-STF 2114, VD-LTF 2116, data field carrying one or more PSDUs (data 2118), and PE 2120. The legacy preamble 2130 includes an indication of U-SIG 2122.
Chen et al. (US 2019/0289612 A1) discloses paragraphs 0057-0058 disclose the STF may be formed from a concatenated sequence of sub-STFs that are defined for smaller bandwidth channels, such as 20 MHz, 40 MHz, 80 MHz or 160 MHz channels. In some implementations, a phase rotation may be applied to at least one of the sub-STFs of the concatenated sequence. The puncturing may be based on a subchannel or a portion (such as a 20 MHz portion) of the wireless channel. In some implementations, the STF may be punctured with minimal impact to the PAPR due to the type of training sequence used and the application of phase rotations.
