Office Action

§103
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 . Continued Examination Under 37 CFR 1.114 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 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 04/12/2026 has been entered. Response to Arguments Applicant’s arguments have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. 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 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 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. Claims 1-3, 6-10, 12-17 & 19-20 are rejected under 35 U.S.C 103 as being unpatentable over Lee et al. (US 2016/0021635), hereon referred to as Lee, in view of Tian et al. (US 2021/0014052), hereon referred to as Tian, in view of Peng et al. (US 2020/0022209), hereon referred to as Peng. In regards to claims 1, 7 & 15, Lee discloses receiving, by a second terminal, first information, sent by a third-party function or a first network function wherein the first information is used to determine a first association relationship between a first terminal and the second terminal (Prior to initiating the operations depicted by call flow, UE may establish a local communication link with the device to obtain identification information for device...UE may then obtain identification information for a device...The UE may register the device to access the wireless network for service over the connection; the registration may include associating the identification information for the device with the network credential of the UE; may establish a local communication link with the device 115-e to obtain identification information for device 115-e...UE 115-f may then obtain identification information 305 for device 115-e...If the association 320 is successful, HSS 210-a (or, in some cases, MME 205-a or another network entity) may send a confirmation message 325 to UE 115-f. The confirmation message 325 may include credentials for device 115-e to use for accessing the wireless network ...UE 115-f may then send credentials for accessing the wireless network 330 for the network to the device 115-e over the local communication link. The credentials for accessing the wireless network 330 may, as discussed, be different from the network credential of the UE; Paragraphs 0050-0065); and sending, by the second terminal, a key material of the first terminal to the third-party function or the first network function based on the first association relationship, wherein the key material of the first terminal comprises security information required for communication performed by the first terminal (If the association is successful, HSS (or another network entity) may send a confirmation message to UE. The confirmation message may include credentials for device to use for accessing the wireless network ...UE may then send credentials for accessing the wireless network for the network to the device over the local communication link. The credentials for accessing the wireless network 330 may, as discussed, be different from the network credential of the UE; may then obtain identification information 305 for device 115-e...If the association 320 is successful, HSS 210-a (or, in some cases, MME 205-a or another network entity) may send a confirmation message 325 to UE 115-f. The confirmation message 325 may include credentials for device 115-e to use for accessing the wireless network ...UE 115-f may then send credentials for accessing the wireless network 330 for the network to the device 115-e over the local communication link.

However, Lee does not disclose the key material of the first terminal is then sent to the first terminal by the third-party function or the first network function. In an analogous art Tian discloses the key material of the first terminal is then sent to the first terminal by the third-party function or the first network function (An intermediate service organization receives a key sent by a third-party; Paragraphs 0175-0180; 0209; 0223-0227). 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 Lee, with the teachings disclosed by Tian regarding the key material of the first terminal is then sent to the first terminal by the third-party function or the first network function. The suggestion/motivation of the combination would have been to provide additional security in payment security and secure infrastructure (Tian; Paragraph 0002). However, the combination of Lee and Tian does not disclose …without being forwarded by the second terminal. In an analogous art Peng discloses …without being forwarded by the second terminal (the SN may send a request message to the MN, and then the MN sends an updated key to the SN and the terminal, where the request message is used to request the updated key from the MN. This process causes a specific latency; When the SN sequentially selects the key, the MN may not send the count value group to the SN, and send the count value group to the terminal; Paragraphs 0175-0185). 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 the combination of Lee and Tian, with the teachings disclosed by Peng regarding …without being forwarded by the second terminal.
