Office Action

§102
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Interpretation Nonfunctional Descriptive Material Claim 20 recites “A non-transitory, computer-readable storage medium storing a compressed bitstream”. There are no recitations of a processor or other element-merely a compressed bitstream content (a compressed bitstream comprising instructions). Under MPEP 2111.05(III), this claim is merely machine-readable media. The Examiner finds that there is no disclosed or claimed functional relationship between the stored bitstream and the medium. Instead, the medium is merely a support or carrier for the bitstream being stored. Therefore, the bitstream stored should not be given patentable weight. See MPEP 2111.05 applying In re Lowry, 32 F.3d 1579, 1583-84, 32 USPQ2d 1031, 1035 (Fed. Cir. 1994); and In re Ngai, 367 F.3d 1336, 70 USPQ2d 1862 (Fed. Cir. 2004). As such, claim 20 is subject to a prior art rejection based on any non-transitory computer readable storage medium known before the earliest effective filing date of the present application. 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 (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 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. Claim(s) 20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by art STEPIN et al., (US 2019/0394464). Claim 20 has been interpreted above as nonfunctional descriptive material under MPEP 2111.05(III) and the case law cited therein because claim 20 recites “A non-transitory computer-readable medium storing a bitstream generated by a method”. As such, claim 20 is subject to a prior art rejection based on any non-transitory computer readable storage medium known before the earliest effective filing date of the present application. In other words, the proper interpretation of claim 20 is merely a machine-readable media in which the media is merely a support or carrier for the bitstream being stored wherein the bitstream stored and the way such bitstream is generated should not be given patentable weight. STEPIN, which is analogous art, discloses non-transitory computer readable storage medium having stored therein a bitstream comprising video information [¶0002 teaches a computer-readable storage medium storing program code]. As such, STEPIN clearly anticipates the non-transitory, computer readable medium storing a bitstream generated by a method. .Allowable Subject Matter Claims 1-19 are allowed. The following is an examiner’s statement of reasons for allowance: the closest prior art STEPIN et al., (US 2019/0394464) which teaches encoding or decoding a frame of a video by reconstructing the frame, and determining one or more filter parameters and filtering in a frequency domain and a pixel domain a block of the reconstructed frame based on the determined filter parameters to obtain a filtered block of the frame; and BOULES, (Adaptive filtering using the fast Walsh-Hadamard transformation, in IEEE Transactions on Electromagnetic Compatibility, vol. 31, no. 2, pp. 125-128, May 1989) which teaches a fast implementation of the least-mean-square error (LMS) adaptive transversal filter implemented using a fast Walsh-Hadamard filter. These references, either singularly or in combination fail to anticipate or render obvious especially the underlined limitations of claim 1 (and the similar apparatus limitations of claim 18) including [a] method for processing video data, comprising: determining, during a conversion between a video comprising a picture and a bitstream of the video, to apply an adaptive Hadamard Domain Filter (HDF) process in addition to an HDF process to samples of the picture, wherein parameters of the HDF process are predefined and parameters of the adaptive HDF process are trained online, and wherein a final output of the adaptive HDF process in addition to the HDF process is generated by a combination of multiple elements; and performing the conversion based on the final output. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to Marnie Matt whose telephone number is (303)297-4255.
