§101 §103
CTNF 18/368,341 CTNF 99377 DETAILED ACTION This action is responsive to the Application/amendment filed on 09/14/2023 . Claims 1-20 are pending in the case. Claims 1, 10, and 19 are independent claims. Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. 07-06 AIA 15-10-15 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. Claim Rejections - 35 USC § 101 07-04-01 AIA 07-04 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1-20 are rejected under 35 U.S.C. 101 because claims are directed towards abstract ideas/mental processes without significantly more. Regarding Claim 1: Subject Matter Eligibility Analysis Step 2A Prong 1: The claim recites generating…based on the first information…a set of network weights which, under the broadest reasonable interpretation, covers performance of the limitation in the mind. The limitations encompass choosing values based on data. See 2106.04.(a)(2).III.C. The claim recites modulating…based on the first information…a set of sine activation amplitudes of the functional representation of the first time series which, under the broadest reasonable interpretation, covers performance of the limitation in the mind. The limitations encompass choosing different values for a variable. See 2106.04.(a)(2).III.C The claim recites imputing…based on the set of network weights and a result of the modulating…the at least one missing value of the first time series which, under the broadest reasonable interpretation, covers performance of the limitation in the mind. The limitations encompass evaluating a pattern and using judgement to determine a value. See 2106.04.(a)(2).III.C. The claim recites that is usable by a sinusoidal representation network model for obtaining a functional representation of the first time series which is an abstract idea (Mathematical Calculations (see MPEP 2106.04(a)(2)(I)(C))).

The claim is not patent eligible. Regarding Claim 5: The rejection of claim 1 is incorporated and further claim recites further additional elements/limitations: Subject Matter Eligibility Analysis Step 2A Prong 1: The claim recites with respect to a predetermined loss function which is an abstract idea (Mathematical Calculations (see MPEP 2106.04(a)(2)(I)(C))).

Claim Rejections - 35 USC § 103 07-20-aia AIA 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. 07-103 AIA The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. 07-23-aia AIA 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. 07-21-aia AIA Claim (s) 1-6 , 8 , 10-15 , 17 and 19-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sitzmann et al(“Implicit Neural Representations with Periodic Activation Functions” henceforth known as Sitzmann) in view of Mehta et al(“Modulated Periodic Activations for Generalizable Local Functional Representations” henceforth known as Mehta) and further in view of Naouret al(“Time Series Continuous Modeling for Imputation and Forecasting with Implicit Neural Representations” henceforth known as Naour) . Regarding claim 1: Sitzmann discloses receiving, by the at least one processor, first information that relates to a latent vector representation (Sitzmann, Page 8, Paragraph 2, “we condition these latent code vectors on partial observations of the signal O ϵ R m through an encoder”) of a first time series (Sitzmann, Supplementary Material, Page 16, Figure 8, “Example frames from fitting a video with SIREN and ReLU MLPs” where a video corresponds to a time series as a video is pixels over time (See also Sitzmann, Supplementary Material, Page 16, Paragraph 5, “Due to the highly periodic nature of audio signals with structure at various time scales, we expect that SIRENs could accurately represent such signals efficiently and provide an alternative representation for audio signals” where the model handling audio at time scales corresponds to handling a time series )) for which at least one value is missing( Sitzmann, Supplementary Material, Page 17, Figure 7, “ We sample 10% of pixels from the ground truth image for training, learning a representation which can inpaint the missing values” where the inpainting of missing pixels corresponds to receiving data with values missing ) Sitzmann discloses generating, by the at least one processor based on the first information, a set of network weights that is usable by a sinusoidal representation network model for obtaining a functional representation of the first time series (Sitzmann, Supplementary Material, Page 19, Paragraph 4, “We use a hypernetwork…which maps the latent code to the weights of a 5-layer SIREN”) Sitzmann does not explicitly disclose modulating, by the at least one processor based on the first information, a set of sine activation amplitudes of the functional representation of the first time series. Mehta discloses modulating, by the at least one processor based on the first information, a set of sine activation amplitudes of the functional representation of the first time series( Mehta, Page 4, Col. 1, Paragraph 2, “the latent codes z can modulate the amplitude of the sine activations of each hidden layer”) References Sitzmann and Mehta are analogous art because they are from the same field of endeavor if using machine learning with implicit neural representations using SIREN’s. Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Sitzmann and Mehta before him or her, to modify the SIREN of Sitzmann to include the modulation of Mehta to adapt to different signals latent code. The suggestion/motivation for doing so would have been Mehta , Page 2, Col. 1, Paragraph 1, “functional mapping that uses two MLPs: a modulator and a synthesis network…The modulator is the key to generalization.” The Sitzmann-Mehta does not explicitly disclose imputing, by the at least one processor based on the set of network weights and a result of the modulating, the at least one missing value of the first time series. Naour discloses imputing, by the at least one processor based on the set of network weights and a result of the modulating, the at least one missing value of the first time series (Naour , Page 8, Paragraph 5, “We compared TimeFlow with the following two-step processing baseline: linear interpolation handling the missing values within the partially observed look-back window,” where imputing the missing values of the time series correspond imputing…the at least one missing value of the first time (See Also Naour , Page 20, Table 13)) References Sitzmann-Mehta and Naour are analogous art because they are from the same field of endeavor if using machine learning with implicit neural representations.
