DETAILED ACTION
1. This office action is in response to U.S. Patent Application No.: 19/180,597 filed on 4/16/2025
with effective filing date 1/25/2018. Claims 1-4 are pending.
Double Patenting
2. 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.

Allowable Subject Matter
After analyzing the current application examiner concluded that the novelty of the current application involves the method involves generating a first predicted sample of a current sample included in a current block based on an intra prediction mode of a current block, where the intra prediction mode of the current block includes intra prediction mode index. A reference sample (AA) corresponding to the current sample is determined among reference samples of the current block based on the intra prediction mode of the current block. Reference value corresponding to the current sample is obtained based on unfiltered sample value of the reference sample. A current sample is restored based on a residual signal of the current sample and a predicted sample, where parameter sets corresponding to specific index set are different from each other according to shape of the current block.
The prior art of record in particular, Heo et al. US 2020/0396483 A1 in view of Seregin et al. US 2017/0272759 A1 and Jang et al. US 2019/0174128 A1 does not disclose, with respect to claim 1, determining a parameter set based on at least one of a width of the current block, a height of the current block, whether the intra prediction mode index is smaller than a first index, and whether the intra prediction mode index is greater than a second index, the parameter set includes at least one of a first parameter for a reference sample on a left side of the current block and a second parameter for a reference sample on an upper side of the current block; generating a second prediction sample by linearly combining the first prediction sample and the at least one reference sample based on the determined parameter set, wherein the determined parameter set is used for determining a weight which is used for linearly combining the first prediction sample and the at least one reference sample; and restoring the current sample based on a residual sample of the current sample and the second prediction sample, wherein any one of the plurality of intra prediction mode indexes included in the specific index set indicates any one of a plurality of angular modes as claimed.
Rather, Heo et al. discloses the method involves acquiring specific value for showing similarity between reference samples for performing intra-prediction of a current block. Intra prediction mode of the current block is determined based on specific threshold value and the obtained value. The current block is restored based on the determined intra prediction mode. A candidate mode list is produced based on the intra prediction mode of a neighbor block of the current block without obtaining flag information for indicating whether the intra-prediction mode of the current block is induced from the neighbor block of the current block. Index information is obtained from bit-stream when the specific for showing the similarity is less than the specific threshold value. Candidate mode is determined based on the index information for indicating the candidate mode list and the intra-prediction mode of the current block.
Similarly, Seregin et al. discloses the method involves receiving (240) a block of video data encoded using a prediction mode. The one or more parameters are determined (242) for the prediction mode based on one or more of the width or the height of the block of video data. The block of video data using the PDPC mode and the determined PDPC parameters is decoded (244). The wireless communication device is a mobile station and the block of video data is received by the receiver and modulated according to a cellular communication standard.
Moreover Jang et al. discloses the method involves determining a current block a square-off block. A reference sample utilized in prediction of the current block is configured (S502) based on breadth and height information of the current block. An intra prediction mode of the current block is drawn. A prediction sample of the current block is produced based on the intra prediction mode of the current block by using the reference sample. A sub block is coincided with a transformation unit in which a residual signal of the current block is transformed.
