Response to Arguments
Applicant’s arguments have been considered but are moot in view of new grounds of rejections.
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, 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.
Claim(s) 1-8, 13, 18, 20 are rejected under 35 U.S.C. 103 as being unpatentable over US 20210195245 A1-Li et al (Hereinafter referred to as “Li”), in view of US 20170374369 A1-Chuang et al (Hereinafter referred toa s “Chu”).

receiving a video bitstream comprising a current block encoded using a first prediction mode ([0149], receives a bitstream);
identifying a first prediction mode for the current block ([0166]);
mapping the first prediction mode to a corresponding intra prediction mode ([0304], wherein IMTS may be used only for intra prediction blocks, or may be used for both intra prediction blocks and inter prediction block);
selecting a first transform set from a plurality of transform sets based on the corresponding intra prediction mode ([0305], wherein selection process for selectively switching transform types); and

Therefore, it would have been obvious to one of ordinary skilled in the art before the effective filing date of the claimed invention to modify the method disclosed by Li to disclose mapping the first prediction mode to a corresponding intra prediction mode using a decoder side intra mode derivation (DIMD) process as taught by Chu, to improve coding efficiency by improving the quality of the intra predictor ([0006], Chu).
Regarding claim 2, Li discloses the method of claim 1, wherein the first prediction mode is an inter prediction mode ([0376], inter prediction).
Regarding claim 3, Li discloses the method of claim 1, wherein the first prediction mode is an intra block copy (IBC) mode ([0650], intra block copy).
Regarding claim 4, Li discloses the method of claim 1, wherein the first prediction mode comprises a template-matching prediction mode ([0661], template matching).
Regarding claim 5, Li discloses the method of claim 1, wherein the first prediction mode comprises a combined inter-intra prediction mode ([0304], both intra and inter are being used; [0415], combined inter merge/intra prediction (CIIP) mode), and wherein the corresponding intra prediction mode is based on intra portion of the combined inter-intra prediction mode ([0438]).
Regarding claim 6, Li discloses the method of claim 1, wherein the first prediction mode comprises a geometric partitioning mode (GPM) ([0743]).
Regarding claim 7, Li discloses the method of claim 6, wherein the corresponding intra prediction mode is based on a split direction of the GPM ([0610], wherein intra prediction is based on splitting pattern).
Regarding claim 8, Li discloses the method of claim 6, wherein the corresponding intra prediction mode is based on an intra prediction portion of the GPM ([0295]).
Regarding claim 13, Li discloses he method of claim 1, further comprising deriving a transform set index for the current block based on the corresponding intra prediction mode, wherein the first transform set is selected using the transform set index ([0304]).
Regarding claim 18, analyses are analogous to those presented for claim 1 and are applicable for claim 18, encode ([0006])
Regarding claim 20, analyses are analogous to those presented for claim 1 and are applicable for claim 20.
Claim(s) 9 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over US 20210195245 A1-Li et al (Hereinafter referred to as “Li”), in view of US 20170374369 A1-Chuang et al (Hereinafter referred toa s “Chu”), in view of US 20130089145 A1-Guo et al (Hereinafter referred to as “Guo”).
Regarding claim 9, Li discloses the method of claim 1,
Li fails to disclose parsing a syntax element from the video bitstream to determine whether to adjust the corresponding intra prediction, wherein the first transform set is selected based on the corresponding intra prediction mode and the syntax element.
However, in the same field of endeavor, Guo discloses parsing a syntax element from the video bitstream to determine whether to adjust the corresponding intra prediction ([0028]), wherein the first transform set is selected based on the corresponding intra prediction mode and the syntax element ([0023]).
Therefore, it would have been obvious to one of ordinary skilled in the art before the effective filing date of the claimed invention to modify the method disclosed by Li to disclose parsing a syntax element from the video bitstream to determine whether to adjust the corresponding intra prediction, wherein the first transform set is selected based on the corresponding intra prediction mode and the syntax element as taught by Guo, to improve coding efficiency ([0058], Guo).
Regarding claim 19, analyses are analogous to those presented for claim 9 and are applicable for claim 19.
Claim(s) 14 rejected under 35 U.S.C. 103 as being unpatentable over US 20210195245 A1-Li et al (Hereinafter referred to as “Li”), in view of US 20170374369 A1-Chuang et al (Hereinafter referred toa s “Chu”), in view of US 20240171752 A1-Kidani.
Regarding claim 14, Li discloses the method of claim 1,
Li fails to disclose wherein the first prediction mode maps to a set of two or more corresponding intra prediction modes, and wherein the corresponding intra prediction mode is selected according to a syntax element in the video bitstream.
