Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 1-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by BROSS et al., "Versatile Video Coding (Draft 3)", 124. MPEG Meeting, Macao, Motion Picture Expert Group or ISO/ IECJTC1/SC29/WG11), no. m45225, XP030215989, Decembers, 2018, 185 pages. referred to as BROSS hereinafter.
Regarding Claim 1, BROSS shows a method for video decoding (Clause 8.3 describes the decoding process for coding units.), the method performed by at least one processor and comprising:
obtaining video data and one or more most probable mode (MPM) lists indicating angular intra prediction modes (8.3.2 expressly derives MPM candidates for intra prediction modes, including angular modes.);
and decoding the video data based on the one or more MPM lists (8.3.2 & 8.3.4 wherein the decoder uses the derived MPM candidate list to determine IntraPredModeY.), wherein at least one of the MPM lists comprises a sequence of candModeList values of a candModeList value, another candModeList value immediately subsequent to the candModeList value, and a second other candModeList value immediately subsequent to the other candModeList value (8.3.2, step 3 explicitly defines six-entry candModeList sequences with ordered candidate positions.), wherein the candModeList value is represented in the at least one of the MPM lists as:
2+((first mode indication+an offset) by a modular operation) (8.3.2, step 3 expressly uses expressions such as 2+((candIntraPredModeA+61)%64).), wherein other candModeList value is represented in the at least one of the MPM lists as:
2+((a second mode indication−an offset) by the modular operation) (8.3.2, step 3 discloses adjacent MPM entries using subtraction/offset-based wrapping.), and wherein the second other candModeList value is represented in the at least one of the MPM lists as:
2+((the first mode indication−(one less than the offset)) by the modular operation) (8.3.2, step 3 corresponds to the +60 term when offset is 61.).
Regarding claim 2, BROSS shows the limitations as per Claim 1 above, wherein the first mode indication and the second mode indication both represent a candIntraPredModeA value (8.3.2 step 3, expressly has an embodiment where both expressions derive from candIntraPredModeA.).
Regarding claim 3, BROSS shows the limitations as per Claim 1 above, wherein the first mode indication represents a minimum of a (candIntraPredModeA, candIntraPredModeB) value, and wherein the second mode indication represents a maximum of the (candIntraPredModeA, candIntraPredModeB) value (8.3.2 step 3, explicitly defines minAB = Min(candIntraPredModeA, candIntraPredModeB) and maxAB = Max(...).).
Regarding claim 4, BROSS shows the limitations as per Claim 1 above, wherein the offset is represented in the at least one of the MPM lists as “61” (8.3.2, step 3 wherein document repeatedly uses +61 and +60 candidate formulas.).
Regarding claim 5, BROSS shows the limitations as per Claim 1 above, wherein the modular operation is represented in the at least one of the MPM lists as “% 64” (8.3.2, step 3 wherein repeatedly uses % 64 in the candidate formulas.).
Regarding claim 6, BROSS shows the limitations as per Claim 1 above, wherein the at least one of the MPM lists comprises a third other candModeList value (8.3.2, step 3 wherein the six-entry MPM list clearly includes at least a third additional candidate.).
Regarding claim 7, BROSS shows the limitations as per Claim 6 above, wherein the at least one of the MPM lists comprises a fourth other candModeList value (8.3.2, step wherein the same six-entry list includes a fourth additional candidate.).
Regarding Claim 8, BROSS shows a method for video encoding, the method performed by at least one processor and comprising:
receiving video data (Clause 6.2 discloses source pictures and their relationship to the processes outlined in the paper.);
and encoding the video data to signal one or more most probable mode (MPM) lists indicating angular intra prediction modes (The encoder signals the MPM list by selecting an index (intra_luma_mpm_idx) that corresponds to an entry in the MPM list derived at the decoder (Clause 8.3.2). The syntax table in 7.3.4.2 defines the bitstream structure for this signaling, and the semantics in 7.4.5 define the mapping of these bits to the MPM candidates.),
wherein at least one of the MPM lists comprises a sequence of candModeList values of a candModeList value, another candModeList value immediately subsequent to the candModeList value, and a second other candModeList value immediately subsequent to the other candModeList value (8.3.2, step 3 explicitly defines six-entry candModeList sequences with ordered candidate positions.), wherein the candModeList value is represented in the at least one of the MPM lists as:
2+((first mode indication+an offset) by a modular operation) (8.3.2, step 3 expressly uses expressions such as 2+((candIntraPredModeA+61)%64).), wherein other candModeList value is represented in the at least one of the MPM lists as:
2+((a second mode indication−an offset) by the modular operation) (8.3.2, step 3 discloses adjacent MPM entries using subtraction/offset-based wrapping.), and wherein the second other candModeList value is represented in the at least one of the MPM lists as:
2+((the first mode indication−(one less than the offset)) by the modular operation) (8.3.2, step 3 corresponds to the +60 term when offset is 61.).
Regarding claim 9, BROSS shows the limitations as per Claim 8 above, wherein the first mode indication and the second mode indication both represent a candIntraPredModeA value (8.3.2 step 3, expressly has an embodiment where both expressions derive from candIntraPredModeA.).
Regarding claim 10, BROSS shows the limitations as per Claim 8 above, wherein the first mode indication represents a minimum of a (candIntraPredModeA, candIntraPredModeB) value, and wherein the second mode indication represents a maximum of the (candIntraPredModeA, candIntraPredModeB) value (8.3.2 step 3, explicitly defines minAB = Min(candIntraPredModeA, candIntraPredModeB) and maxAB = Max(...).).
Regarding claim 11, BROSS shows the limitations as per Claim 8 above, wherein the offset is represented in the at least one of the MPM lists as “61” (8.3.2, step 3 wherein document repeatedly uses +61 and +60 candidate formulas.).

performing a conversion between a visual media file and a bitstream of a visual media data according to a format rule (Clause 6.1), wherein the bitstream signals one or more most probable mode (MPM) lists indicating angular intra prediction modes (8.3.2 wherein the syntax format necessarily signals the MPM by nature of its creation.),
wherein at least one of the MPM lists comprises a sequence of candModeList values of a candModeList value, another candModeList value immediately subsequent to the candModeList value, and a second other candModeList value immediately subsequent to the other candModeList value (8.3.2, step 3 explicitly defines six-entry candModeList sequences with ordered candidate positions.), wherein the candModeList value is represented in the at least one of the MPM lists as:
