DETAILED ACTION 1. Claims 1-20 are pending in this examination. Notice of Pre-AIA or AIA Status 2.1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 2.2. 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. Response to Arguments 3. Applicant's arguments have been considered but are moot in view of the new ground(s) of rejection. Claim Rejections - 35 USC § 103 4.1. The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. 4.2. Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over US Patent Application No. 20210368341 to Liao et al (“Liao”) in view of US Patent Application No. 20200323030 to Mehta et al (“Mehta”), and in view of US Patent No. 11496474 issue to Xia et al (“Xia”). As per claim 1, Liao discloses a personal internet of things network (PIN) creation method ([0089] ... High Level Service flows includes the following: Step 1, Users configuration and corresponding User Profiles; Step 2, Registration of PIN device and Update of User Profiles for services; Step 3, Accessing services provided by PIN devices; Step 4, UE policies in the home settings), comprising: sending, by a user equipment, networking request information to a PIN server , wherein the user equipment is a personal internet of things network element with management capability (PEMC) ([0163] ... A PIN Element can have both PIN management capability and Gateway Capability"), Liao does not explicitly disclose however in the same field of endeavor, Mehta discloses wherein the networking request information is used to request to create a PIN [0113] In one embodiment, the owner of the gateway node 106-N may send a request for joining the new mesh network 102 via the client application 323 communicatively coupled or paired with the gateway node 106-N. The owner of the gateway node 106-N logs in into the client application 323 and requests for addition of gateway node 106-N to the new mesh network 102. The request may comprise for example, name of the new mesh network 102 and the user access token 241 associated with the client application 323. In one embodiment, the client application 323 requests the gateway node 106-N for network creation at step 331. The gateway management module 246 of the gateway node 106-N receives the network creation request and generates a second request for network creation that includes the gateway access token 236 in addition to network name and the user access token 241. The gateway management module 246 forwards the second request to the management server 114 at step 332); and receiving, by the user equipment, networking response information from the PIN server, wherein the networking response information comprises creation success information or creation failure information, the creation success information indicates that the PIN is successfully created ([0115]…the gateway management module 246 also transmits a SUCCESS message at step 338-2 to the management server 114 for creation of the mesh network 102 and addition of the gateway node 106-N to the mesh network 102. The network management module 293 creates the mesh network 102 and adds gateway node 106-N to the mesh network 102 at step 338-3. On successful addition of the gateway node 106-N to the mesh network 102, the network management module 293 of the management server 114 transmits a SUCCESS message to the gateway node 106-N at step 338-4. The gateway management module 246 of the gateway node 106-N further transmits a SUCCESS message to the client application 323 at step 338-5 confirming addition of the gateway node 106-N to the mesh network 102). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teaching of Liao with the teaching of Mehta by including the feature of creation information, in order for Liao’s system to receiving confirmation of ownership rights of the at least one gateway node and adding to one of a new and existing mesh overlay network to create the mesh overlay network based on successful verification of the ownership rights of the at least one gateway node. [0010] In yet another embodiment, the present disclosure relates to a method of creating and managing a decentralized IP-based mesh overlay network of one or more nodes. The method comprising transmitting a provisioning request to a mesh network management server and receiving a gateway access token and firmware provisioned in response to authentication of the mesh network management server and the at least one gateway node. The method further comprising transmitting a request for ownership from a client application of the user of the at least one gateway node to the mesh network management server, wherein the request for ownership includes a gateway access token received from the mesh network management server, and a user access token associated with the client application. Upon verification of the gateway access token and the user access token, the method comprising receiving confirmation of ownership rights of the at least one gateway node and adding to one of a new and existing mesh overlay network to create the mesh overlay network based on successful verification of the ownership rights of the at least one gateway node (Mehta, [0010]). Liao and Mehta do not explicitly disclose however in the same field of endeavor, Xia discloses the creation failure information indicates that the PIN fails to be created (col.7, lines 20-50… the mesh configuration is pushed to the mesh point 200, the cloud system 204 may send a reload command to the mesh point 200 to cause the mesh point 200 to reload and the newly pushed mesh configuration to take effect. In contrast, if the mesh point 200 is not successfully authenticated at the cloud system 204, the authentication response 220 may indicate that the mesh point 200 has been rejected from the mesh deployment. The mesh portal 202 may convey this rejection to the mesh point 200 and the process may halt) It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teaching of Liao with the teaching of Mehta/Xia by including the feature of failure information, in order for Liao’s system to authenticate the mesh point, and upon authentication, the correct mesh configuration may be delivered to the mesh point. In some embodiments, the mesh point receives the mesh configuration from the cloud system via the mesh portal. In particular, the mesh portal may have an uplink to the cloud system and downlinks to mesh points in the mesh network such that the cloud system can communicate the mesh configuration to the mesh point via the mesh portal.
