CTFR 18/520,074 CTFR 78716 DETAILED ACTION 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. Response to Arguments Applicant's arguments have been fully considered but they are not persuasive. The applicant argues that neither Bush (US 2024/0333398, hereon referred to as Bush nor Giuseppe et al. (WO 2023/155977) , hereon referred to as Giu, alone or in combination teach/suggest all of the elements of the independent claim(s). The applicant argues that the prior art is silent regarding “selecting one of the quantum capabilities based on the user application characteristic.” The applicant mentions that a network slice is different thana quantum capability like quantum key distribution, quantum cryptography, and quantum computing. Therefore, selecting a network slice is different than selecting a quantum capability from a set of available quantum capabilities. However, the Examiner respectfully disagrees. As currently presented, the claim language recites “one of the quantum capabilities”, plural, only requiring that more than one exists. The claim language does not explicitly require they be different kinds. The “set of different quantum capabilities” is read in from the specification, and limitations from the spec are not imported into the claims. The applicant also argues that the prior art is silent regarding “providing the selected one of the quantum capabilities to the user communication device over one of the network slices”. The applicant mentions that Celozzi discloses a quantum channel compromises a physical fiber optic channel between a wireless communication network and a user equipment. The applicant argues that providing a quantum capability to a user device like remote quantum computing is different than the physical capable link between the user device and the network. However, the Examiner respectfully disagrees. As currently presented, the claim language recites “providing the selected one of the quantum capabilities to the user communication device over one of the network slices”. The applicant mentions “remote quantum computing” being different from “physical fiber optic channel”, but the claim does not explicitly mention “remote quantum computing.” This is a feature in the specification that is not currently in the claim. Claim Rejections - 35 USC § 103 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 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. 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 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. 07-21-aia AIA Claim s 1-8, 10-13, 21-27 are rejected under 35 U.S.C 103 as being unpatentable over Bush (US 2024/0333398, hereon referred to as Bush, in view of Giuseppe et al.

NSSF may have optional quantum key distribution parameters for enhanced security; a connection establishment message is received via a wireless communication from UE 120 to connect the UE 120 to the wireless communication network 110. The connection establishment message requests quantum secure communications; multiplexing the quantum channel to generate keys for different users on separate time slots or frequencies. In other words, quantum key distribution may be sliced by running several logical quantum channels in the same fiber, by either time multiplexing or frequency multiplexing the quantum channels. such slices may be referred to as quantum key distribution network slices; Paragraphs 0030-0035; 0040-0050; 0070-0075; Fig.3). However, Bush does not disclose connecting the user communication device to the selected one of the quantum capabilities over one of the network slices. In an analogous art Giu discloses connecting the user communication device to the selected one of the quantum capabilities over one of the network slices (A quantum channel is established between the wireless communication network and the UE, as described herein, the quantum channel is a physical fiber optic channel between the wireless communication network and the user equipment. In some embodiments, establishing a quantum channel between the wireless communication network and the UE includes providing a service function to establish the quantum channel; 10-15) . At the time before the effective filing date of the invention, it would have been obvious to the one with ordinary skill in the art to combine the teachings disclosed by Bush, with the teachings disclosed by Giu regarding connecting the user communication device to the selected one of the quantum capabilities over one of the network slices.
