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 . A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.1 14, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.1 14. Applicant's submission filed on 5/26/2026 has been entered. Claims 1-34 are presented for further examination. DETAILED ACTION Response to Arguments Applicant's arguments filed 5/26/2026 have been fully considered but they are not persuasive. Applicant states that the references fail to disclose the amended limitations. Examiner respectfully disagrees. Campbell (US 10,778,755) in view of Samadi (US 2021/0344582) specifically Cambell discloses the following: In Claim 1: Campbell discloses ….simulating network feedback representing expected feedback from a second system (“the gather data under performance test with respect to the target nodes, to what performance may be expected/predicted accuracy for the UE devices/particular node/second system remotely from the first system at the geolocation”, refer to Col 17, Lines 1-3, Col 2, Lines 43-61, Col 14, Lines 1-15, Col 16, Lines 5-15, Lines 65- Col 17, Lines 10, Lines 42-50, Col 17, Lines 60- Col 18, Lines 5 and Col 21, Lines 4) for at least one communication channel (refer to Fig 4, and Col 8, Lines 30-65 and Col 14, Lines 30- Col 15, Lines 10, Col 16, Lines 40-65 and Col 17, Lines 1-16), wherein the simulated network feedback includes at least one simulated network parameter (gathered data/performance , refer to Col 17, Lines 1-5), … wherein the second system communicates with a first system via at least one network, wherein the at least one value is synthetically generated (refer to Col 17, Lines 42- Col 18, Lines 20, Col 15, Lines 32-35 particular node is determined to be supporting a particular amount of network traffic); wherein each decision-making process is configured to determine decisions for the first system based on network feedback data (refer to Col 21, Lines 45- Col 22, Lines 5, Col 25, Lines 1-20). In Claim 4: Campbell discloses ….wherein the first set of network feedback is generated locally to the first system, wherein the second set of network feedback is generated by the second system remotely from the first system (the feedback is generated by the UE device and another from the outside system/node, refer to Col 18, Lines 1-60: round way trip, and one way trip for measuring delays for either sending or receiving timestamps at the communication systems/devices and Col 19 ,Lines 1-18, Col 22, Lines 15-31). In Claim 34: Campbell discloses applying at least one generative artificial intelligence model in order to generate a set of simulation results, wherein the simulation network feedback is based on the generated set of simulation results (performance be process with machine learning/other technologies, refer to col 21, Lines 10-20, and process within each node/device, refer to Col 19, 60-67 and Col 21, Lines 65-67, Col 25, Lines 1-20). Therefore, arguments are not persuasive and the rejection is therefore maintained. 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. Claim(s) 1-34 is/are rejected under 35 U.S.C. 103 as being unpatentable over Campbell et al hereinafter Campbell (US 10,778,755) in view of Samadi (US 2021/0344582). Referring to Claim 1.
