Office Action

§103
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 . DETAILED ACTION The amendment filed 01/08/2026 has been entered. Claims 1-7, 9-14 and 16-20 remain pending in the application. Response to Arguments Applicant' s arguments with respect to claim(s) 1, 10, 17 and all subsequent dependent claims have been considered but are moot in view of the references cited in the most current rejection. 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 (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 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. 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. 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. Claim(s) 1-7, 9-14 and 16-20 are rejected under 35 U.S.C. 103 as being unpatentable over Liu (US 20230074047 A1) in view of Di (US 20230109902 A1) and Zhang (CN 110163114 A, all citations provided from machine translation attached).

(Abstract, Paragraphs 4-6, Claims 1, 3) Zhang teaches inputting to the second neural network the features extracted by the first neural network (when training the second neural network model, using the previously trained the first neural network model). (Page.6, Last paragraph) It would have been obvious to one having ordinary skill in the art before the effective filling date to have modified Liu to incorporate using a second neural network to output a predicted function as taught by Di in order to generate seismic images and identify reflections in the seismic image and to attenuate the low frequency noise and further modify Liu to incorporate inputting to the second neural network the features extracted by the first neural network as taught by Zhang in order to improve image quality and improve the accuracy of subsequent analysis and prediction.

(Abstract, Paragraphs 4-6, Claims 1, 3) It would have been obvious to one having ordinary skill in the art before the effective filling date to have modified Liu to incorporate using a second neural network in order to generate seismic images and identify reflections in the seismic image and to attenuate the low frequency noise. Regarding claim 5, Liu teaches wherein the training data set comprises synthetically generated velocity models and corresponding Green's functions. (Paragraphs 60-61, 67) Regarding claim 6, Liu teaches wherein the synthetically generated velocity models are derived from a geological model, and the corresponding Green's functions are determined based on a simulation of seismic wave propagation from a source location to a receiver location. (Paragraphs 60-61, 67) Regarding claim 7, Liu teaches wherein the first neural network comprises a transformer network or a U-network. (Paragraphs 37, 50, 56-57, Fig.5) Regarding claim 9, Liu teaches wherein the first neural network comprises a U- network. (Paragraphs 37, 50, 56-57, Fig.5) Liu does not explicitly teach the second neural network comprises a transformer network. Di teaches the second neural network comprises a transformer network. (Abstract, Paragraphs 4-6, Claims 1, 3, 10, 17) It would have been obvious to one having ordinary skill in the art before the effective filling date to have modified Liu to incorporate the second neural network comprises a transformer network in order to generate seismic images and identify reflections in the seismic image and to attenuate the low frequency noise. Regarding claim 10, Liu teaches a system (64) for generating seismic images of a subsurface formation, the system comprising: at least one processor (64) and a memory (66) storing instructions that when executed by the at least one processor cause the at least one processor to perform operations comprising: obtaining seismic data (36) representing the subsurface formation. (Abstract, Paragraphs 31, 36, 39, Figs.2, 4) Liu also teaches generating velocity models for the subsurface formation based on the seismic data (receiving a velocity model corresponding to at least one attribute of seismic data, receiving source wavelet data corresponding to the seismic data).

(Paragraphs 11, 56-57, Fig.5) Liu also teaches generating seismic images of the subsurface formation based on the seismic data and the predicted Green's functions. (Paragraphs 11, 52, 54, 67) Liu does not explicitly teach using a second neural network to output a predicted function and inputting to the second neural network the features extracted by the first neural network. Di teaches using a second neural network to output a predicted function. (Abstract, Paragraphs 4-6, Claims 1, 3) Zhang teaches inputting to the second neural network the features extracted by the first neural network (when training the second neural network model, using the previously trained the first neural network model). (Page.6, Last paragraph) It would have been obvious to one having ordinary skill in the art before the effective filling date to have modified Liu to incorporate using a second neural network to output a predicted function as taught by Di in order to generate seismic images and identify reflections in the seismic image and to attenuate the low frequency noise and further modify Liu to incorporate inputting to the second neural network the features extracted by the first neural network as taught by Zhang in order to improve image quality and improve the accuracy of subsequent analysis and prediction. Regarding claims 11 and 18, the claims disclose substantially the same limitations, as claim 2. All limitations as recited have been analyzed and rejected with respect to claims 11 and 18, and do not introduce any additional narrowing of the scopes of the claims as analyzed. Therefore, claims 11 and 18 are rejected for the same rational over the prior art cited in claim 2. Regarding claim 12, the claim discloses substantially the same limitations, as claim 3.
