Office Action

§102 §103 §112
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 . Claim Rejections - 35 USC § 112 Claim 9 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being incomplete for omitting essential elements, such omission amounting to a gap between the elements. See MPEP § 2172.01. The omitted elements are: determining, by the one or more processors, based on the relative difference metric, whether to synthesize the current frame by a generative neural network without entropy coding. For purposes of examining, the examiner will treat claims 9 as similar to claim 1. 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(s) 1,8,9, and 16 is/are rejected under 35 U.S.C. 102(a)(1)(2) as being anticipated by CN113099161. Regarding claim 1, CN meets the claim limitations, as follows: A method comprising: computing, by one or more processors of a computing system, a relative difference metric describing differences in features between a current frame and a reference frame (i.e. key point displacement coding information would be a difference metric between the current frame and reconstructed frame) [abs]; and determining, by the one or more processors, based on the relative difference metric, whether to synthesize the current frame by a generative neural network without entropy coding (i.e. neural network used to encode the motion information of the region of interest (ROI). Entropy coding is used for lossless compression and the neural network based coding can be used for coding which does not require lossless coding) [abs; step 2]. Claim 8 is rejected using similar rationale as claim 1. This is the decoder of claim 1. Decoders perform the inverse operation as the encoder. Claim 9 is rejected using similar rationale as claim 1. Claim 16 is rejected using similar rationale as claim 8. 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 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. 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. 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 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) 2, 10 and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over CN in view of Zhang US 20220385907. Regarding claim 2, CN do/does not explicitly disclose(s) the following claim limitations: wherein computing the relative difference metric further comprises: inputting, by the one or more processors, the current frame and the reference frame into a learning model; and outputting, by the one or more processors, current keypoints of the current frame and reference keypoints of the reference frame. However, in the same field of endeavor Zhang discloses the deficient claim limitations, as follows: wherein computing the relative difference metric further comprises: inputting, by the one or more processors, the current frame and the reference frame into a learning model (i.e. input frames into NN (learning model)) [5,44,96]; and outputting, by the one or more processors, current keypoints of the current frame and reference keypoints of the reference frame (i.e. encoded in terms of key frames) [96]. It would have been obvious to one with ordinary skill in the art at the time of filing to modify the teachings of CN with Zhang to compute the relative difference metric further comprises: inputting, by the one or more processors, the current frame and the reference frame into a learning model; and outputting, by the one or more processors, current keypoints of the current frame and reference keypoints of the reference frame. It would be advantageous because "“the machine learning system can increase the compression and/or decompression performance, bitrate, quality, and/or efficiency for a particular set of data.” [45]. Therefore, it would have been obvious to one with ordinary skill, in the art at the time of filing, to modify the teachings of CN with Zhang to obtain the invention as specified in claim 2. Claim 10 is rejected using similar rationale as claim 2. Claim 17 is rejected using similar rationale as claim 1 and further below. Zhang meets the claim limitations, as follows: A method comprising: training, by one or more processors of a computing system, a generative neural network without a discriminator; and training, by the one or more processors of a computing system, the generative neural network with a discriminator (i.e. many types of neural networks exists without a discriminator. Discriminators are used in generative adversarial networks (GAN) and are not used in entropy coding) [48]. Claim(s) 3 and 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over CN and Zhang in view of Valin US 20140286399. Regarding claim 3, CN and Zhang do/does not explicitly disclose(s) the following claim limitations: wherein computing the relative difference metric further comprises: calculating, by the one or more processors, an absolute difference of the current keypoints and the reference keypoints However, in the same field of endeavor Valin discloses the deficient claim limitations, as follows: wherein computing the relative difference metric further comprises: calculating, by the one or more processors, an absolute difference of the current keypoints and the reference keypoints [63]. It would have been obvious to one with ordinary skill in the art at the time of filing to modify the teachings of CN and Zhang with Valin to have wherein computing the relative difference metric further comprises: calculating, by the one or more processors, an absolute difference of the current keypoints and the reference keypoints. It would be advantageous because “Unfortunately, such systems and methods have drawbacks such as blurriness due to loss of energy detail, activity masking overhead, and inefficient representation of coefficients. Embodiments of the present disclosure address these and other issues.” [2-3]. Therefore, it would have been obvious to one with ordinary skill, in the art at the time of filing, to modify the teachings of CN and Zhang with Valin to obtain the invention as specified in claim 3. Claim 11 is rejected using similar rationale as claim 3. Allowable Subject Matter Claims 4-7 and 12-15 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Regarding claim 4, Zhang meets the claim limitations, as follows: The method of claim 3, wherein computing the relative difference metric further comprises: dividing, by the one or more processors, (i.e. frames divided in groups of N frames for video processing) [181]. The prior arts do not disclose: the absolute difference by a mean of a moving window, wherein the moving window comprises a previous absolute difference Regarding claim 7, the prior arts do not disclose: comparing, by the one or more processors, the relative difference metric to a relative difference threshold.
