Office Action

§102
DETAILED ACTION This action is in response to the application filed on 06/20/2025. Claims 1-14 are pending. Acknowledgment is made of a claim for foreign priority. of the certified copies of the priority documents have been received. 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 . Bitstream Claim interpretation Claim 14 is directed to a computer readable medium that stores generated bitstream. The bitstream is being treated as a product that is the result of the process (method). The steps are not required elements of claim 3, so they only limit the invention in terms of how they define the contents of the information in the bitstream. MPEP §2113 The contents of the bitstream, defined by how the bitstream was generated, only describes the content of the information in the bitstream and as result are descriptive language. See MPEP §2111.05. The bitstream has no functional relationship with the claimed non-transitory computer-readable recording medium. Claim Mapping Notation In this office action, following notations are being used to refer to the paragraph numbers or column number and lines of portions of the cited reference. In this office action, following notations are being used to refer to the paragraph numbers or column number and lines of portions of the cited reference. [0005] (Paragraph number [0005]) C5 (Column 5) Pa5 (Page 5) S5 (Section 5) Furthermore, unless necessary to distinguish from other references in this action, “et al.” will be omitted when referring to the reference. Claim Rejections - 35 USC § 102 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 following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim 14 is rejected under 35 U.S.C. 102(a1) and (a2) as being anticipated by Thirumalai et al. (US 20170280139 A1) 14. A method of transmitting a bitstream generated by an image encoding method, the image encoding method comprising: determining a current block by partitioning a picture; determining a tree type of the current block; resetting a residual sample based on color space conversion being applied; determining transform coefficient based on the reset residual sample; determining quantization parameter based on the color space conversion being applied; and encoding the transform coefficient based on the quantization parameter,wherein the determining of the quantization parameter is performed by performing clipping on the quantization parameter such that a value of the quantization parameter has a value less than or equal to a predetennined upper limit value and greater than or equal to a predetermined lower limit value,wherein the predetermined upper limit value is derived based on sum of quantization parameter range offset and a predetermined constant value,wherein the whether the color space conversion for the residual sample of the current block is applied is derived based on the tree type of the current block, andwherein the color space conversion is not applied based on the tree type of the current block not being a single tree.3 [0042] The destination device 14 may receive, via link 16, the encoded video data to be decoded. The link 16 may comprise any type of medium or device capable of moving the encoded video data from the source device 12 to the destination device 14. In the example of FIG. 1A, the link 16 may comprise a communication medium to enable the source device 12 to transmit encoded video data to the destination device 14 in real-time. The encoded video data may be modulated according to a communication standard, such as a wireless communication protocol, and transmitted to the destination device 14. The communication medium may comprise any wireless or wired communication medium, such as a radio frequency (RF) spectrum or one or more physical transmission lines. The communication medium may form part of a packet-based network, such as a local area network, a wide-area network, or a global network such as the Internet. The communication medium may include routers, switches, base stations, or any other equipment that may be useful to facilitate communication from the source device 12 to the destination device 14. Allowable Subject Matter Claims 1-13 are allowed. Conclusion A shortened statutory period for reply to this action is set to expire THREE MONTHS from the mailing date of this action. An extension of time may be obtained under 37 CFR 1.136(a). However, in no event, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this action.
