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 of this title, 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.
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 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 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 pre-AIA 35 U.S.C. 103(a) 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 non-obviousness.
This application currently names joint inventors. In considering patentability of the claims under pre-AIA 35 U.S.C. 103(a), the examiner presumes that the subject matter of the various claims was commonly owned at the time any inventions covered therein were made absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and invention dates of each claim that was not commonly owned at the time a later invention was made in order for the examiner to consider the applicability of pre-AIA 35 U.S.C. 103(c) and potential pre-AIA 35 U.S.C. 102(e), (f) or (g) prior art under pre-AIA 35 U.S.C. 103(a).
Claims 1-4, 6, 21-24, 26, 28-31, and 33 are rejected under 35 U.S.C. 103 as being unpatentable over Gao (US Patent 11,451,787 B2), (“Gao”), in view of Xie et al. (JVET-Z0117-v3), (“Xie”).

Gao does not explicitly disclose the following claim limitations (Emphasis added).

It would have been obvious to one with an ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Gao with Xie to implement the set of 32 interpolation filters of Xie.
Therefore, the combination of Gao with Xie will reduce the artifacts and improve visual quality [Xie: Abstract, Tables 2 & 3].
Claims 5, 7, 25, 27, and 32 are rejected under 35 U.S.C. 103 as being unpatentable over Gao (US Patent 11,451,787 B2), (“Gao”), in view of Xie et al. (JVET-Z0117-v3), (“Xie”), in view of Zhao et al. (US Patent 10,382,781 B2), (“Zhao”).
Regarding claims 5, 25, and 32, Gao meets the claim limitations as set forth in claims 4, 24, and 31. Gao further meets the claim limitations as follow.
determining a position among 32 positions corresponding to the 32 interpolation filters that is closest to a fractional portion of the upsampled locations (When the resolution of the reference frame is lower than the resolution of the current frame, upsampling is performed on the reference frame to obtain a target reference frame) [Gao: col. 15, line 27-30]; and selecting an interpolation filter from the set of 32 interpolation filters that corresponds to the determined position (The sampling proportion may be represented by a ratio of a resolution after sampling to a resolution before the sampling, or may be represented by a ratio of a resolution before sampling to a resolution after sampling) [Gao: col. 8, line 6-10].
Gao does not explicitly disclose the following claim limitations (Emphasis added).
determining a position among 32 positions corresponding to the 32 interpolation filters that is closest to a fractional portion of the upsampled locations; and selecting an interpolation filter from the set of 32 interpolation filters that corresponds to the determined position.
However, in the same field of endeavor Xie further discloses the deficient claim limitations as follows:
identifying the filter from the set of 32 interpolation filters (Discrete cosine transform interpolation filter(DCT-lF) has proven to be an effective interpolation filter for
motion compensation in H.265 and H.266. ln this proposal, the 6-tap filter coefficients is also derived by using DCT-lF for chroma components) [Xie: Page 1; Please also see the set of 32 6-tap interpolation filter for chroma components listed in Table 1].
It would have been obvious to one with an ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Gao with Xie to implement the set of 32 interpolation filters of Xie.
Therefore, the combination of Gao with Xie will reduce the artifacts and improve visual quality [Xie: Abstract, Tables 2 & 3].
In addition, in the same field of endeavor Zhao further discloses the deficient claim limitations and the claim limitations as follows:
determining a position (video encoder 20 and/or video decoder 30 may select a first interpolation filter from a plurality of interpolation filters for a block when a width-to-height ratio of the block is within a pre-defined range) [Zhao: col. 27, line 66-67] among 32 positions corresponding to the 32 interpolation filters ((Short g_ailntraGaussFilter[32][4]) [Zhao: col. 17, line 7]; (Short g_ailntraCubicFilter[32][4]) [Zhao: col. 16, line 43]; (Short g_ailntraSexticFilter[32][6]) [Zhao: col. 26, line 45]; (means for selecting an interpolation filter from a plurality of interpolation filters for a block of video data based on a size of the block of video data and based on an intra-prediction mode for the block of video data, wherein the plurality of interpolation filters comprises a Gaussian filter and a discrete cosine transform (DCT) based filter; means for determining, using one or more characteristics of the interpolation filter, a number of reference samples to be stored at a reference buffer; means for generating a plurality of values corresponding to the number of reference samples in the reference buffer, wherein the means for generating the plurality of values comprises means for increasing the number of reference samples in the reference buffer by a threshold along both a row and a colunm of the block of video data) [Zhao: col. 41, line 15 – col. 42, line 13]) that is closest to a fractional portion of the upsampled locations (video encoder 20 and/or video decoder 30 may perform a clipping operation on the reference sample location such that nearest available reference sample may be used for the N-tap interpolation.) [Zhao: col. 27, line 66-67]; and
selecting an interpolation filter (video encoder 20 and/or video decoder 30 may select a first interpolation filter) [Zhao: col. 27, line 66-67] from the set of 32 interpolation filters that corresponds to the determined position (Short g_ailntraSexticFilter[32][6]) [Zhao: col. 26, line 45].
It would have been obvious to one with an ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Gao, Xie, with Zhao to implement Zhao’s method.
Therefore, the combination of Gao, Xie, with Zhao will reduce the computational complexity by reducing or eliminating a number of clipping operations as well as reducing or eliminating intra reference sample mapping processes [Zhao: col. 4, line 31-41].
Regarding claims 7 and 27, Gao meets the claim limitations as set forth in claims 1 and 21. Gao and Xie do not explicitly disclose the following claim limitations (Emphasis added).
wherein the upsampled reference frame is stored in a buffer.
However, in the same field of endeavor Xie further discloses the deficient claim limitations as follows:
wherein the upsampled reference frame is stored in a buffer (a number of reference samples to be stored at a reference buffer) [Zhao: col. 39, line 25-26].
It would have been obvious to one with an ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Gao, Xie, with Zhao to implement Zhao’s method.
Therefore, the combination of Gao, Xie, with Zhao will reduce the computational complexity by reducing or eliminating a number of clipping operations as well as reducing or eliminating intra reference sample mapping processes [Zhao: col. 4, line 31-41].
