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 claims at issue 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); and 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 a nonstatutory double patenting ground provided the reference application or patent either is shown to be commonly owned with this 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 §§ 706.02(l)(1) - 706.02(l)(3) 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 USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/forms/.

Claims 1-3 of the instant application are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3 of the U.S. Patent 12,200,202 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claims are broader than the claims in the US Patent 12,200,202 B2.
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 of this title, 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.
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under pre-AIA 35 U.S.C. 103(a) are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims under pre-AIA 35 U.S.C. 103(a), the examiner presumes that the subject matter of the various claims was commonly owned at the time any inventions covered therein were made absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and invention dates of each claim that was not commonly owned at the time a later invention was made in order for the examiner to consider the applicability of pre-AIA 35 U.S.C. 103(c) and potential pre-AIA 35 U.S.C. 102(e), (f) or (g) prior art under pre-AIA 35 U.S.C. 103(a).
Claims 1-3 are rejected under 35 U.S.C. 103 as being unpatentable over Lee (US Patent 11,184,639 B2), (“Lee”), in view of Lim et al. (US Patent 11,218,704 B2), (“Lim”).

For example, at least one of a reference sample adjacent to the left corner of a current block, a reference sample adjacent to the top right comer of a current block, or a reference sample adjacent to the bottom left corner of a current block may be used for intra weighted prediction.) [Lee: col. 33, line 54-60], wherein, based on the intra luma reference index information having a value of 0, the image information includes a flag for the ISP ((partition unit information) [Lee: col. 8, line 10]; (the number of intra prediction mode candidates (e.g., the number of MPMs) used for determining an intra prediction mode of a current block) [Lee: col. 19, line 58-60]), and wherein the flag for the ISP (partition unit information) [Lee: col. 8, line 10] specifies whether the current block is partitioned (i.e. A prediction unit may be one of partitions partitioned into a square or a rectangular shape having the same size in a single coding unit, or a prediction unit may be one of partitions partitioned so that one prediction unit of prediction units partitioned in a single coding unit have a different shape and/or size from other prediction unit) [Lee: col. 5, line 39-44, col. 11, line 45 – col. 17, line 25; Figs. 3-7, 15].
Lee does not explicitly disclose the following claim limitations (Emphasis added).

wherein, based on the intra luma reference index information having a value of 0, the image information includes a flag for the ISP
However, in the same field of endeavor, Lim also discloses the claim limitations as follows:
wherein, based on the intra luma reference index information (When the indicator indicates that multiple reference sample lines are used, reference sample line indexes are also signaled. For example, mrl_index is signaled. Therefore, it
is possible to determine which reference sample lines are used) [Lim: col. 2, line 21-24] having a value of 1, the second reference line is a reference line which is one sample away from the upper boundary or the left boundary of the current block (When the indicator mrl_index has a value of 1, a second reference sample line which is second closest to the current block is utilized) [Lim: col. 2, line 21-24; Figs. 9, 20-21] – Note: Figures 9, 20, and 21 show the second reference sample line, which is second closest to the current block, is one sample away from the upper boundary or the left boundary of the current block. Please see more details in Figures 9, 20, and 21).
wherein, based on the intra luma reference index information having a value of 0 (When the indicator mrl_index has a value of 0, a first reference sample line which is closest to the current block is utilized) [Lim: col. 2, line 21-24], the image information includes a flag for the ISP ((a prediction block partition flag) [Lim: col. 13, line 58]; (i.e. In embodiments, each of specific information, data, flag, index, element and attribute, etc. may have a value. A value of information, data, flag, index, element and attribute equal to "0" may represent a logical false or the first predefined value. In other words, a value "0", a false, a logical false and the first predefined value may be replaced with each other. A value of information, data, flag, index, element and attribute equal to "1" may represent a logical true or the second predefined value. In other words, a value "1", a true, a logical true and the second predefined value may be replaced with each other) [Lim: col. 6, line 52-62]).
It would have been obvious to one with an ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Lee with Lim to program the system to implement of Lim’s method.
Therefore, the combination of Lee with Lim will enable the system to improve the accuracy of the intra-picture prediction [Lim: col. 55, line 60-61].

In addition, it is also possible to use a larger number of intra prediction modes than shown in FIG. 8) [Lee: col. 19, line 58-64]); wherein the intra-prediction mode includes an intra planar mode, an intra DC mode or at least one intra angular mode (i.e. The candidate list may further include a default mode.

is possible to determine which reference sample lines are used) [Lim: col. 2, line 21-24] having a value of 1, the second reference line is a reference line which is one sample away from the upper boundary or the left boundary of the current block (When the indicator mrl_index has a value of 1, a second reference sample line which is second closest to the current block is utilized) [Lim: col. 2, line 21-24; Figs. 9, 20-21] – Note: Figures 9, 20, and 21 show the second reference sample line, which is second closest to the current block, is one sample away from the upper boundary or the left boundary of the current block. Please see more details in Figures 9, 20, and 21).
wherein, based on the intra luma reference index information having a value of 0 (When the indicator mrl_index has a value of 0, a first reference sample line which is closest to the current block is utilized) [Lim: col. 2, line 21-24], the image information includes a flag for the ISP ((a prediction block partition flag) [Lim: col. 13, line 58]; (i.e. In embodiments, each of specific information, data, flag, index, element and attribute, etc. may have a value. A value of information, data, flag, index, element and attribute equal to "0" may represent a logical false or the first predefined value. In other words, a value "0", a false, a logical false and the first predefined value may be replaced with each other. A value of information, data, flag, index, element and attribute equal to "1" may represent a logical true or the second predefined value. In other words, a value "1", a true, a logical true and the second predefined value may be replaced with each other) [Lim: col. 6, line 52-62]).
It would have been obvious to one with an ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Lee with Lim to program the system to implement of Lim’s method.
Therefore, the combination of Lee with Lim will enable the system to improve the accuracy of the intra-picture prediction [Lim: col. 55, line 60-61].
