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 .
Claim Rejections - 35 USC § 103
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 (i.e., changing from AIA to pre-AIA ) 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 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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 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.
Claim(s) 1 - 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Han et al (US 2019/0394491, hereafter Han) in view of Lim et al (US 2019/0273922, hereafter Lim).
As per claim 1, a method of video decoding performed at a computing system having memory and one or more processors, the method comprising:
receiving a video bitstream comprising a plurality of blocks and a first indicator associated with one or more partitioning types (¶ 52);
parsing, from the video bitstream, the first indicator; when the first indicator has a first value, partitioning a first block of the plurality of blocks according to a first partitioning mode, including partitioning the first block into N equal-sized subblocks (¶ 72).
However, Han does not explicitly teach wherein N = 2M and wherein M is a positive integer that is greater than 2; and decoding the first block in accordance with the partitioning.
In the same field of endeavor, Lim teaches wherein N = 2M and wherein M is a positive integer that is greater than 2; and decoding the first block in accordance with the partitioning (¶ 632).
Therefore, it would have been obvious for one of ordinary skill in the art at the time the invention was effectively filed to modify the invention of Han in view of Lim. The advantage is an improvement in video coding.
As per claim 2, Han discloses the method of claim 1.
However, Han does not explicitly teach wherein N is a fixed number.
In the same field of endeavor, Lim teaches wherein N is a fixed number (¶632).
Therefore, it would have been obvious for one of ordinary skill in the art at the time the invention was effectively filed to modify the invention of Han in view of Lim. The advantage is an improvement in video coding.
As per claim 3, Han discloses the method of claim 1.
However, Han does not explicitly teach further comprising parsing a value for N from the video bitstream.
In the same field of endeavor, Lim teaches further comprising parsing a value for N from the video bitstream (¶ 632).
Therefore, it would have been obvious for one of ordinary skill in the art at the time the invention was effectively filed to modify the invention of Han in view of Lim. The advantage is an improvement in video coding.
As per claim 4, Han discloses the method of claim 1, wherein each subblock of the N equal-sized subblocks is square (¶ 72).
As per claim 5, Han discloses the method of claim 1, wherein the first block is a superblock (¶ 25).
As per claim 6, Han discloses the method of claim 1, wherein the first block is partitioned into the N equal-sized subblocks when the first block has a size that meets one or more criteria (¶ 81).
As per claim 7, Han discloses the method of claim 1, wherein the first partitioning mode is restricted to a predetermined number of uses with the first block (¶ 33).
As per claim 8, Han discloses the method of claim 1, wherein the first partitioning mode is applied to the first block in a recursive manner (¶ 26).
As per claim 9, Han discloses the method of claim 1, further comprising parsing, from the video bitstream, a second indicator that indicates whether the first partitioning mode is enabled at a first partitioning point of the first block (¶ 52).
As per claim 10, Han discloses the method of claim 9, wherein the second indicator is signaled in conjunction with a third indicator, the third indicator indicating that the first block is split into more than one subblock (¶ 52 and 72).
As per claim 11, Han discloses the method of claim 9, wherein the second indicator is encoded using a first context, the first context being based on a comparison between a block size of the first block and one or more neighboring block sizes (¶ 129).
As per claim 12, Han discloses the method of claim 11, wherein the first context is the same as a context for partitioning a block into 4 equal-sized subblocks (¶ 72).
As per claim 13, Han discloses the method of claim 11, wherein the first block corresponds to a first picture, and wherein the first context is based on a partitioning flag of a second block of the plurality of blocks, the second block corresponding to another picture, different than the first picture (¶ 52 and 72).
As per claim 14, Han discloses the method of claim 11, wherein the first block corresponds to a first color component, and wherein the first context is based on a partitioning flag of a second block of the plurality of blocks, the second block corresponding to a second color component, different than the first color component (¶ 66).
As per claim 15, Han discloses the method of claim 1, wherein block partitioning context is based on whether the first partitioning mode has been applied to a parent partitioning node for the first block (¶ 75).
As per claim 16, Han discloses the method of claim 1, wherein the first indicator is signaled via a high-level syntax of the video bitstream (¶ 52).
Regarding claim 17, arguments analogous to those presented for claim 1 are applicable for claim 17.
Regarding claim 18, arguments analogous to those presented for claim 5 are applicable for claim 18.
Regarding claim 19, arguments analogous to those presented for claim 4 are applicable for claim 19.
Regarding claim 20, arguments analogous to those presented for claim 1 are applicable for claim 20.
