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 .
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, 13, and 20 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1, and 15 of copending Application No. 19037924 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because See Table 1 for details.

Allowable Subject Matter
Claims 2-12, and 14- 19 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Closest prior art listed below either singularly or in combination, fail to anticipate or render the above limitations obvious.
Xiang Zhang (US20230014820A1) is directed to methods and apparatus for mesh coding, including compression and decompression of 3D mesh data. A processing system decodes a point cloud from a bitstream using a point cloud compression decoder, where the points correspond to mesh vertices or sampled polygon points. Based on the decoded point cloud, the system estimates connectivity information among vertices and reconstructs mesh frame. Additional data such as texture maps decoded by a video decoder and texture coordinates decoded by an attribute decoder may be used to enhance the reconstructed mesh. The system also incorporate connectivity differences from the bitstream to refine connectivity information. For dynamic meshes containing sequences of frames, the system supports interframe connectivity prediction by estimating the connectivity of a current frame using reference connectivity from previously reconstructed frames.
Lauri Ilola (US20230050860A1) is directed to a method and system for encoding a 3D representation of an object by projecting it onto one or more 2D patches and generating corresponding geometry and texture images. A mesh is then constructed from the geometry image, producing vertices that are mapped to 2D coordinates in the texture image. These texture coordinates are signaled in a bitstream so they can be applied to the mesh vertices during decoding, enabling proper texture mapping of the reconstructed 3D object. The signaling may be carried through metadata structures, syntax elements, or attribute maps within volumetric video coding frameworks, and may include configurable parameters such as mapping types, flags, or atlas metadata.
