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 .
This office action is in response to application filed 10/31/2024 in which the claims 1, 13-14 are pending.
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.

Claims 1, 13-14 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 13-14 of U.S. Patent No. US 12,137,240 B2 in view of Lim et al. (US 2012/0314771 A1).
Although the claims at issue are not identical, they are not patentably distinct from each other because the examined application claim is obvious over the conflicting patent claim. The difference between the instant claim 1, 13-14 and conflicting patent claim 1, 13-14 are that instant claim are apparatus claims & instant claims 13-14 also includes
additional limitations generate residual samples of the current block based on the prediction samples; generate residual information based on the residual samples in the instant claim. See the table below. However Lim discloses the apparatuses for encoding and decoding a video by blocks through examples shown in FIGS. 1 to 8, and Para [0099] teaches the subtracter 120 generates a residual block of the current block by subtracting the predicted block from the current block. Here, the outputted residual block includes a residual signal which has a value obtained by subtracting the predicted pixel value of the predicted block from the original pixel value of the current block.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to utilize limitation in the method of the conflicting patent claim, since Image encoding/decoding apparatus for a communication device and the apparatus improves the compression efficiency of the image.
