Claim Rejections - 35 USC § 103
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.
Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over Sonoda in view of Manolakos et al (US 2021/0050888) (hereinafter Manolakos).
Regarding claim 6, Sonoda does not expressly disclose the information transmission method of claim 1, wherein in a case that the communications device is a terminal and a communications peer is a terminal, the obtaining channel quality of a plurality of antenna channels comprises: transmitting a sidelink reference signal through the plurality of antenna channels; and receiving channel quality fed back by the communications peer, wherein the channel quality is obtained by the communications peer through measurement based on the sidelink reference signal.
Manolakos discloses the above recited limitations. In particular, Manolakos discloses the information transmission method of claim 1, wherein in a case that the communications device is a terminal and a communications peer is a terminal (see Manolakos, Fig. 4, e.g., UE 120a and 120b), the obtaining channel quality of a plurality of antenna channels comprises:

[0065], e.g., At 412, the UE 120b may transmit, to the UE 120a, the feedback report based at least in part on the CSI report configuration).
It would have been obvious to a person of ordinary skilled in the art before the effective filing date of the claimed invention to incorporate Manolakos’ teachings into Sonoda. The suggestion/motivation would have been to provide channel state information associated with sidelink air interfaces as suggested by Manolakos.
Double Patenting
Claims 1-20 of this application is patentably indistinct from claims 1-7, 10-11 and 14-20 of Application No. 18/315,920. Pursuant to 37 CFR 1.78(f), when two or more applications filed by the same applicant or assignee contain patentably indistinct claims, elimination of such claims from all but one application may be required in the absence of good and sufficient reason for their retention during pendency in more than one application. Applicant is required to either cancel the patentably indistinct claims from all but one application or maintain a clear line of demarcation between the applications. See MPEP § 822.
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.

Claims 1-20 provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-7, 10-11 and 14-20 of copending Application No. 18/315,920 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because both the application and copending application are direct to the subject matter of an information transmission method involving a plurality of antenna channels where claims are not patentably distinct from each other.
