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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 02/25/2026 has been entered.
Response to Arguments
Applicant’s arguments with respect to claim(s) 15-26 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
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) 15-19, 21, and 23, 25 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tsai et al., (U.S. Pub. No. 2022/0228832 A1) in view of Wang et al., (U.S. Pub. No. 2022/0014793 A1).
As per claim 15, Tsai teaches an encoder ([0021], [0028]), comprising: circuitry ([0084], [0089]), the circuitry, in operation: sets a parameter to a first value in response to a current boundary being a sub-block transform (SBT) boundary between partitions included in a single transform block on which the SBT is performed (fig. 13, abstract, [0030-0031] and fig. 11), the parameter being utilized to determine a strength of a deblocking filter (table 1, fig. 13 el. 1320 and [0030-0031] and [0084], [0086]), wherein, in the SBT, the single transform block is divided into partitions (fig. 11 and fig. 13), and an orthogonal transform is selectively performed on one or more of the partitions (fig. 7), wherein the current boundary is inside the single transform block and is different from a boundary between different transform blocks (fig. 11 and abstract, and [0030-0031], [0052], [0061], [0073], [0081]); and applies the deblocking filter to the current boundary according to the parameter (fig. 13). Although Tsai discloses the claimed encoder ([0021], [0028]), Tsai does not explicitly disclose the claimed memory coupled to the circuitry, as recited in claim 15.
However, Wang teaches the claimed memory coupled to the circuitry (fig. 1A-B).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to incorporate the teachings of Wang with Tsai in order to provide improved compression and decompression techniques that improve compression ratio with little to no sacrifice in picture quality are desirable.
As per claim 16, Tsai (modified by Wang) as a whole teaches everything as claimed above, see claim 15. In addition, Tsai teaches wherein the SBT, the single transform block is divided into two partitions (fig. 11), and the orthogonal transform is selectively performed on one the partitions (fig. 7).
As per claim 17, which is the corresponding decoder with the limitations of the encoder as recited in claim 15, thus the rejection and analysis made for claim 15 also applies.
As per claim 18, which is the corresponding decoder with the limitations of the encoder as recited in claim 16, thus the rejection and analysis made for claim 16 also applies.
As per claim 19, Tsai teaches an encoder, comprising: sets a first parameter to a first value in response to a current boundary between partitions being included in a single transform block on which a sub-block transform (SBT) is performed (fig. 13 el. 1310, [0086]), the first value indicating applying a deblocking filter to the current boundary (fig. 13 el. 1320, table 1, [0006] [0086]), wherein, in the SBT, the single transform block is divided into partitions (fig. 11), and an orthogonal transform is selectively performed on one or more of the partitions (fig. 7), wherein the current boundary is inside the single transform block and is different from a boundary between different transform blocks (fig. 11); determines a second parameter different from the first parameter (table 2); and applies the deblocking filter corresponding to the second parameter to the current boundary (fig. 13, table 1). Although Tsai discloses an encoder ([0021]), comprising circuitry ([0089]), Tsai does not explicitly disclose memory coupled to the circuitry, as recited in claim 19.
However, Wang teaches a memory coupled to the circuitry (fig. 1A-B).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to incorporate the teachings of Wang with Tsai in order to provide improved compression and decompression techniques that improve compression ratio with little to no sacrifice in picture quality are desirable.
As per claim 21, which is the corresponding decoder with the limitations of the encoder as recited in claim 19, thus the rejection and analysis made for claim 19 also applies here.
As per claim 23, Tsai (modified by Wang) as a whole teaches everything as claimed above, see claim 15. In addition, Tsai teaches wherein at least one of the partitions has a non-zero transform coefficient ([0030-0031], [0081]).
As per claim 25, which is the corresponding decoder with the limitations of the encoder as recited in claim 23, thus the rejection and analysis made for claim 23 also applies.
Claim(s) 20, 22, 24 and 26 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tsai et al., (U.S. Pub. No. ) in view of Wang et al., (U.S. Pub. No. 2022/0014793 A1) and further in view of Wedi et al., (U.S. Pub. No. 2014/0056350 A1).
As per claim 20, Tsai (modified by Wang) as a whole teaches everything as claimed above, see claim 19. Tsai does not explicitly disclose wherein the second parameter includes a first value corresponding to a first deblocking filter and a second value corresponding to a second deblocking filter stronger than the first deblocking filter.
However, Wedi teaches wherein the second parameter includes a first value corresponding to a first deblocking filter and a second value corresponding to a second deblocking filter stronger than the first deblocking filter ([0027-0028], “selecting a first or second deblocking filter for being applied to the block boundary using a threshold that is defined based on the second parameter, wherein the first and the second deblocking filters have different strengths”).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to incorporate the teachings of Wedi with Tsai (modified by Wang) for the benefit to improve scheme for deciding deblocking and selecting appropriate deblocking filters, abstract.
As per claim 22, which is the corresponding decoder with the limitations of the encoder as recited in claim 20, thus the rejection and analysis made for claim 20 also applies here.
As per claim 24, Tsai (modified by Wang) as a whole teaches everything as claimed above, see claim 15. Tsai does not explicitly disclose wherein the parameter includes: a first value corresponding to a first deblocking filter, a second value corresponding to a second deblocking filter stronger than the first deblocking filter, and a third value indicating that the deblocking filter is not applied.
However, Wedi teaches wherein the parameter includes: a first value corresponding to a first deblocking filter (fig. 7 and [0107]), a second value corresponding to a second deblocking filter stronger than the first deblocking filter (fig. 7 and [0107]), and a third value indicating that the deblocking filter is not applied (fig. 7 and [0107]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to incorporate the teachings of Wedi with Tsai (modified by Wang) for the benefit to improve scheme for deciding deblocking and selecting appropriate deblocking filters, abstract.
As per claim 26, which is the corresponding decoder with the limitations of the encoder as recited in claim 24, thus the rejection and analysis made for claim 24 also applies.
