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) 72-78 and 89-92 are rejected under 35 U.S.C. 103 as being unpatentable over Lee (US 2023/0015638) in view of Chang (US 2021/0314623).
For claims 72, 90, and 91, Lee discloses a method of processing video data, comprising:
during a conversion between a current video block of a video and a bitstream of the video ([0056] Encoder: means an apparatus performing encoding. That is, means an encoding apparatus. [0057] Decoder: means an apparatus performing decoding. That is, means an decoding apparatus.),

Lee does not expressly disclose performing the conversion based on a motion-compensated prediction sample refinement process applied to the GPM block.
Chang teaches performing the conversion based on a motion-compensated prediction sample refinement process applied to the GPM block ([0130] e.g. sps_gpm_enabled_flag specifies whether geometric partition based motion compensation can be used for inter prediction.) It would be obvious to a person with ordinary skill in the art to combine the geometric partition based motion compensation teachings of Chang with the teaching of Lee for the predictable improvement providing an encoded representation of the video data conforming to a video coding standard.
For claim 73, Lee discloses wherein performing the conversion comprises: applying the motion-compensated prediction sample refinement process for at least one prediction sample of the GPM block by at least one technique comprising: an overlapped block-based motion compensation, a multi-hypothesis prediction, a local illumination compensation, a combined inter-intra prediction, or a bi-directional optical-flow based motion refinement ([0209] The derivation method of the motion information may be different depending on the prediction mode of the current block. For example, a prediction mode applied for inter prediction includes an AMVP mode, a merge mode, a skip mode, a merge mode with a motion vector difference, a subblock merge mode, a geometric partitioning mode, an combined inter intra prediction mode, affine mode, and the like. Herein, the merge mode may be referred to as a motion merge mode.).
For claim 74, Lee discloses the wherein applying the motion-compensated prediction sample refinement process for the at least one prediction sample of the GPM block by the overlapped block-based motion compensation comprises:
refining the at least one prediction sample by using neighboring block's motion information with a weighted prediction, or
wherein applying the motion-compensated prediction sample refinement process for the at least one prediction sample of the GPM block by the multi-hypothesis prediction comprises: weighting the at least one prediction sample from accumulating more than one prediction signals from multiple hypothetical motion data, or
wherein applying the motion-compensated prediction sample refinement process for the at least one prediction sample of the GPM block by the local illumination compensation comprises:

wherein applying the motion-compensated prediction sample refinement process for the at least one prediction sample of the GPM block by the bi-directional optical-flow based motion refinement comprises: in accordance with a determination that a bi-prediction is used, performing a pixel-wise motion refinement on top of a block-wise motion compensation, or
wherein applying the motion-compensated prediction sample refinement process for the at least one prediction sample of the GPM block by the bi-directional optical-flow based motion refinement comprises: in accordance with a determination that two motion vectors of two parts of the GPM block are from two different directions, performing the bi-directional optical-flow based motion, or
wherein applying the motion-compensated prediction sample refinement process for the at least one prediction sample of the GPM block by the overlapped block-based motion compensation comprises: performing the overlapped block-based motion compensation for all subblocks of the GPM block, or
wherein applying the motion-compensated prediction sample refinement process for the at least one prediction sample of the GPM block by the overlapped block-based motion compensation comprises: performing the overlapped block-based motion compensation for a portion of subblocks of the GPM block or the at least one sample of the GPM block, or
wherein applying the motion-compensated prediction sample refinement process for the at least one prediction sample of the GPM block by the overlapped block-based motion compensation comprises: performing the overlapped block-based motion compensation for at least one subblocks of the GPM block at block boundaries of the GPM block, or
wherein applying the motion-compensated prediction sample refinement process for the at least one prediction sample of the GPM block by the overlapped block-based motion compensation comprises: performing the overlapped block-based motion compensation for the at least one prediction sample at block boundaries of the GPM block, or
wherein applying the motion-compensated prediction sample refinement process for the at least one prediction sample of the GPM block by the overlapped block-based motion compensation comprises: applying the overlapped block-based motion compensation based on a reference subblock based motion data of the GPM block and a neighboring GPM block, or
wherein applying the motion-compensated prediction sample refinement process for the at least one prediction sample of the GPM block by the overlapped block-based motion compensation comprises: applying the overlapped block-based motion compensation based on motion data derived from GPM merge candidates ([0295] Whether the current block is a geometric partitioning mode may be determined depending on one or more inter prediction modes ([0296] For example, when at least one or all of a subblock merge mode, a regular merge mode or a combined intra inter mode is not performed with respect to the current block, the inter prediction mode of the current block may be determined as a geometric partitioning mode. That is, when all of a subblock merge flag, a regular merge flag and a combined intra inter prediction flag indicate not to perform (merge_subblock_flag=0 && regular_merge_flag=0 && ciip_flag=0), the inter prediction mode of the current block may be determined as a geometric partitioning mode, and at least one of a partitioning index, a merge list index or a weight may be signaled.).
For claim 75, Lee discloses the wherein applying the overlapped block-based motion compensation based on the reference subblock based motion data comprises: determining blending weights of the overlapped block-based motion compensation based on motion similarities between the reference subblock based motion of a GPM subblock of the GPM block and motion of neighbor subblocks of the neighboring GPM block ([0134] In general, mode selection unit 202 also controls the components thereof (e.g., motion estimation unit 222, motion compensation unit 224, and intra-prediction unit 226) to generate a prediction block for a current block (e.g., a current CU, or in HEVC, the overlapping portion of a PU and a TU).).
For claim 76, Lee discloses the method of claim 72, wherein the method further comprises: determining whether a feature or tool is to be applied on top of the GPM block based on a temporal layer identifier (ID) of a current picture among a structure of a group of pictures (GOP) ([0347] The above embodiments of the present invention may be applied depending on a temporal layer. In order to identify a temporal layer to which the above embodiments may be applied, a corresponding identifier may be signaled, and the above embodiments may be applied to a specified temporal layer identified by the corresponding identifier); and
in accordance with a determination that a current picture locates at pre-defined layer identifiers, applying the feature or tool to the GPM block without an additional signalling, or wherein the method further comprises:determining whether a feature or tool is to be applied on top of the GPM block based on a temporal layer identifier (ID) of a current picture among a structure of a group of pictures (GOP); and in accordance with a determination that a signalling indicating layer identifiers of pictures associated with the GPM block to be applied with the feature or tool is obtained, applying the feature or tool on the GPM block ([0347] Herein, the identifier may be defined as the lowest layer or the highest layer or both to which the above embodiment may be applied, or may be defined to indicate a specific layer to which the embodiment is applied. In addition, a fixed temporal layer to which the embodiment is applied may be defined.).

Here, the geometric partitioning mode may mean a mode in which prediction is performed by partitioning a current block into asymmetric subblocks.).
For claim 89, Lee discloses the method of claim 72, wherein the conversion comprises decoding the current video block from the bitstream of the video, or wherein the conversion comprises encoding the current video block into the bitstream of the video ([0307] FIG. 13 is a view illustrating an image decoding method according to an embodiment of the present invention.).

Allowable Subject Matter
Claims 79-88 objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Response to Arguments
Applicant's arguments filed 22 Oct 2025 have been fully considered but they are not persuasive.
Applicant argues Chang fails to disclose or suggest the claimed limitation of a “motion-compensated prediction sample refinement process" and “performing the conversion based on a motion-compensated prediction sample refinement process applied to the GPM block” because Chang is “. . . is completely silent about refining a result of the geometric partition based motion compensation.”
However, the broadly claimed “performing the conversion based on a motion-compensated prediction sample refinement process applied to the GPM block” does not exclude Chang teachings of performing the conversion based on a motion-compensated prediction sample refinement process ([0130]: e.g. “inter prediction” describes amotion-compensated prediction sample refinement process)
applied to the GPM block ([0130] e.g. sps_gpm_enabled_flag specifies whether geometric partition based blocks are used).
Accordingly, Chang teaches the claimed limitation.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
