DETAILED ACTION
This Office Action is in response to the amendment filed on 07/03/2026, wherein claims 1-20 have been examined and are pending.
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 .
Response to Amendment/ Argument
Applicant's amendment and arguments with respect to claims 1, 10 and 18, filed on 07/03/2026, have been considered but are not persuasive. Chen discloses all limitations of independent claims 1, 10 and 18. See rejection below.
Regarding claims 1, 10 and 18, Applicant argues that Chen does not disclose the limitation wherein the current CU is partitioned into a first predicted part and a second predicted part, and at least one of the first predicted part and the second predicted part is an IBC-predicted part; wherein the prediction for the current CU is obtained by weighted-averaging a first prediction for the first predicted part and a second prediction for the second predicted part, wherein none of the first prediction for the first predicted part and the second prediction for the second predicted part is IBC-Template Matching (TM) prediction; or the prediction for the current CU is obtained based on the first prediction for the first predicted part and the second prediction for the second predicted part, wherein at least one of the first prediction for the first predicted part and the second prediction for the second predicted part is IBC-TM prediction as cited in the claims. However, Chen [0145] discloses two merge indexes one for each partition. After the two partitions are predicted, a blending process using adaptive weights can be used for each predicted partition. Hence, weighted averaging first and second IBC merge prediction can be used. Wherein GPM can be combined with different prediction types. Each of two geometric partitions can be predicted with three different prediction types including IBC mode in different configurations including intra-IBC, IBC-IBC which is both partitions are predicted with IBC as in [0154]-[0159]. Hence, none of the partitions is IBC-Template Matching in this case Chen [0157] discloses that if both partitions are predicted with a same prediction type, no blending may be used along a boundary of the two partitions, hence, first partition and second partitions cannot have the same prediction type at the same time which includes IBC-TM for both partitions even if IBC-TM can be used. Therefore, Chen discloses the prediction for the current CU is obtained by weighted-averaging a first prediction for the first predicted part and a second prediction for the second predicted part, wherein none of the first prediction for the first predicted part and the second prediction for the second predicted part is IBC-Template Matching (TM) prediction as cited in claims 1, 10 and 18.

Patentability shall not be negated by the manner in which the invention was made.
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 AIA 35 U.S.C. 103 are summarized as follows:

One having ordinary skill in the art would be motivated to include that configuration since it has been held that choosing from a finite number of identified, predictable solutions, with a reasonable expectation of success (i.e. to set the duration of sensing cycle when mass of particles deposited on the sensor element reaches a pre-set/predetermined mass) is obvious. KSR International Co. v Teleflex Inc., 550 U.S. 418, 82 USPQ2d 1385, 1395-97 (2007).
Chen does not explicitly disclose wherein the predefined direction is 45 degrees, the first IBC prediction is located in a bottom-right part and the second intra prediction is located in a upper-left part of the current CU.
However, Lim discloses wherein the predefined direction is 45 degrees, the first prediction is located in a bottom-right part, and the second prediction is located in a upper-left part of the current CU (Lim Fig. 21, [0881]-[0903]: geometric partitioning can be used to generate to partitions including a bottom-right part and an upper-left part as in Fig. 21; [1606]-[1614]: direction value of the GPM can include 45 degrees).
It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to use the system and method having first IBC prediction and second intra prediction, as disclosed by Chen, and further incorporate having wherein the predefined direction is 45 degrees, the first IBC prediction is located in a bottom-right part, and the second intra prediction is located in a upper-left part of the current CU, as taught by Lim, for effective image compression (Lim [0004]).
Claims 19-20 are rejected under AIA 35 U.S.C. 103 as being unpatentable over Chen et al. (U.S. 2023/0034458) hereinafter Chen, in view of Kadono et al. (U.S. 2006/0268989) hereinafter Kadono.
Regarding claim 19, Chen discloses a non-transitory computer-readable storage medium for storing computer-executable instructions, when the computer-executable instructions are executed by one or more computer processors, the computer-executable instructions cause the one or more computer processors to perform the method for video encoding of claim 10 to generate the bitstream as cited in claim 10 above.
Kadono discloses storage medium storing a bitstream (Kadono [0060]: generating bitstream and store in a storage medium).
It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to use the system and method, as disclosed by Chen, and further incorporate having the storage medium storing a bitstream, as taught by Kadono, for accessing and using of bitstream when desired (Kadono [0060]).
Regarding claim 20, Chen discloses a method of storing a bitstream, comprising: performing the method for video encoding of claim 10 to generate a bitstream as discussed in claim 10.
Chen does not explicitly disclose storing the bitstream.
However, Kadono discloses storage medium storing a bitstream (Kadono [0060]: generating bitstream and store in a storage medium).
It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to use the system and method, as disclosed by Chen, and further incorporate storing the bitstream, as taught by Kadono, for accessing and using of bitstream when desired (Kadono [0060]).
