DETAILED ACTION
1. This office action is in response to U.S. Patent Application No.: 18/945,493 filed on 10/28/2025 with effective filing date 10/11/2016. Claims 1-3 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.

3. Claims 1-3 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1-15 of U.S. Patent No. 11,838,546 B2 and claim 1-14 of U.S. Patent No. 10,924,762 B2. Although the claims at issue are not identical, they are not patentably distinct from each other.

Allowable Subject Matter
4. After analyzing the current application examiner concluded that the novelty of the current application involves drawing an intra prediction mode about a current block. Left side environmental samples and upper side environmental samples of multi-lines and multiple columns about the current block are drawn. A row of upper side reference samples is drawn based on the upper side environmental samples. A prediction sample about the current block is produced according to the intra prediction mode by using left side reference samples and the upper side reference samples. Weighted values about the upper side environmental samples are drawn.
The prior art of record in particular, Jin et al. US 2018/034469 A1 in view of Wang et al. US 2012/0314767 A1 does not disclose, with respect to claim 16, wherein the left neighboring samples include left neighboring samples of an n-th column located in a left direction away from a leftmost column of the current block, wherein n is more than 1, wherein a number of the left neighboring samples of the n-th column is more than 2N based on a size of the current block being N×N, wherein N is a positive integer, wherein sample values of additional left neighboring samples located to downward of a 2N-th left neighboring sample among the left neighboring samples of the n-th column are derived to be equal to a sample value of the 2N-th left neighboring sample without determining whether the additional left neighboring samples are positioned at unavailable sample positions, and wherein coordinates of the 2N-th left neighboring sample is (−n,2N−1) based on coordinates of a top-left sample in the current block being (0, 0) as claimed.
Rather, Jin et al. discloses the predictive sample value of the current block is obtained by using the sample among samples included in the neighboring reference area of multiple lines located in the intra-prediction direction indicated by the intra-prediction mode from the current block, thus enabling to predict the predictive sample value of the current block by using the samples, and hence enabling to improve the decoding efficiency.
Similarly, Wang et al. teaches the method involves performing a padding operation that processes a set of border pixels according to an order that starts at a bottom-left border pixel and proceeds through the border pixels sequentially to a top-right border pixel, where the padding operation assigns a value to unavailable border pixel based on a value of a border pixel previously processed by the padding operation when the padding operation processes an unavailable border pixel. An intra-predicted video block is generated based on the border pixels.
The same reasoning applies to claims 2 & 3.
