Office Action

§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 . Examiner’s Remarks Claims 1-6, 24-38, 74-83 and 87-91 are withdrawn as of December 15, 2025, with traverse. Claims 10-12, and 14-20, are examined. Claims 1-6, 24-38, 74-83 and 87-91 have been withdrawn for examination. Claims 7-9, 13, 21-23, 39-73, 84-86 and 92-94 are formally canceled. This application contains 1-6, 24-38, 74-83 and 87-91 are drawn to an invention nonelected with traverse. Applicant is reminded that upon the cancellation of claims, 1-6, 24-38, 74-83 and 87-91, to a non-elected invention, the inventorship must be amended in compliance with 37 CFR 1.48(b) if one or more of the currently named inventors is no longer an inventor of at least one claim remaining in the application. Any amendment of inventorship must be accompanied by a request under 37 CFR 1.48(b) and by the fee required under 37 CFR 1.17(i). Applicant is reminded that upon the cancellation of claims to a non-elected invention with Applicant’s amendment and response to this Non-final office action. The requirement is still deemed proper and is therefore made FINAL. This final office action is in response to the amendment and arguments filed on April 23, 2026. Examiner formally withdraws the Claim objections and the rejection under 35 USC 112, and 102. Applicant arguments have been considered. This office action is made final at this time. Allowable Subject Matter Claims 10-12 and 14-20 are allowed over the prior art made of record. The following is a statement of reasons for the indication of allowable subject matter: In regards to Independent Claim 10, BRI (broadest reasonable interpretation) in light of the specification, Examiner finds the claimed invention is patentably distinct from the prior art of record, which sets forth in the following: Wu et al., (US Patent Publication No. 20190380033 A1), the closes prior made of record relates to providing identity privacy over a trusted or untrusted non-3GPP access network in a wireless communication system are disclosed. In some embodiments, a method of operation of a wireless device comprises sending a message to a gateway (ePDG, N3IWF or TWAG) where the message comprises an anonymous user identity; receiving a request for obfuscating the user identity wherein the request comprises a server certificate; and validating the server certificate and sending a response message back to the gateway, comprising the user identity obfuscated by a public key associated with the server certificate. Similar methods are provided on the gateway side and AAA server side. In this manner, the user identity is protected when establishing the connection to the core network and protects against a man in the middle attack. However, Wu fails to show “receiving, from the Non-3GPP access element, a list of networks, by Non-3GPP access element at least has the support for the UE identity privacy; determining, based on the list of networks, whether UE identity privacy should be used for communication with a Non-3rd Generation Partnership Project 'Non-3GPP' access network for the UE; and depending on a result of the determination, transmitting, to a Non-3GPP access element in the Non-3GPP access network, a request message for access authentication that includes an identity of the UE.” … as claimed and supports throughout the specification. Pertinent Prior Art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Wu et al., (US Patent Publication No. 20190380033 A1), “User Identity Privacy Protection In Public Wireless Local Access Network, WLAN, Access” (December 12, 2019) discloses providing identity privacy over a trusted or untrusted non-3GPP access network in a wireless communication system are disclosed. In some embodiments, a method of operation of a wireless device comprises sending a message to a gateway (ePDG, N3IWF or TWAG) where the message comprises an anonymous user identity; receiving a request for obfuscating the user identity wherein the request comprises a server certificate; and validating the server certificate and sending a response message back to the gateway, comprising the user identity obfuscated by a public key associated with the server certificate. Similar methods are provided on the gateway side and AAA server side. In this manner, the user identity is protected when establishing the connection to the core network and protects against a man in the middle attack. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
