`
`The present application, filed on or after March 16, 2013, is being examined under the
`
`first inventor to file provisions of the AIA.
`
`Priority
`
`This application discloses and claims only subject matter disclosed in prior application
`
`and namesthe inventor or at least one joint inventor namedin the prior application. Accordingly,
`
`this application may constitute a continuation or division.
`
`Information Disclosure Statement
`
`The information disclosure statements (IDS)s submitted on 01/31/2022 and 01/08/2024

`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 effectivefiling 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 text of those sections of Title 35, U.S. Code not included in this action can be found
`
`in a prior Office action.
`
`The factual inquiries for establishing a background for determining obviousness under
`
`35 U.S.C. 103 are summarized asfollows:
`
`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 pertinentart.

`
`optimal coefficients].

`chroma channels and generating new coefficient values].
`
`Misra disclosesthe limitations of the claim. However, Misra does not explicitly disclose
`
`right shift by 7 bits on the first coefficient value.
`
`Li more explicitly discloses right shift by 7 bits on the first coefficient value [TBLS 2-5,
`
`Figs. 3-7, 0151-0165; calculating dynamic shift parameters].
`
`It would have been obvious to one of ordinary skill in the art before the effectivefiling
`
`date to incorporate the teachings of Misra with the teachings of Li as stated above. By
`
`incorporating the teachings as such improvedpicture quality is achieved (see Li 0010).
