Double Patenting
The non-statutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper time wise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A non-statutory double patenting rejection is appropriate where the claims at issue are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the reference application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).

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 1-6, 8-12 and 14-19 are rejected under 35 U.S.C. 103 as being unpatentable over Kakadia et al. [hereinafter as Kakadia], US 2009/0196183 A1 in view of Shukla et al. [hereinafter as Shukla], US 2018/0167420 A1 further in view of Hua et al. [hereinafter as Hua], US 2014/0359340 A1.
Regarding claim 1, Kakadia discloses wherein a method in a node of a plurality of nodes (Fig.1 [0037], a radio access network/base station node), the method comprising:
establishing communication with one or more user equipment devices (Fig.1 [0037], serving/establishing communication with one or more client devices/user equipment devices);
managing, one or more network sessions for the one or more user equipment devices (Fig.1 [0014], managing one or more multimedia network sessions with the one or more client devices/user equipment devices);
communicating, with the one or more user equipment devices via the one or more
network sessions (Fig.1 [0037], the one or more mobile devices 13 are communicating to the base station node via the one or more multimedia network sessions);
transmitting, a health check message to one or more other nodes of the plurality of nodes (Fig.1 [0041]-[0042], transmitting SIP signaling/health check message to the one or more SIP servers 43, a number of Session Border Controllers 45 and 47/ one or more other nodes and Fig.7-8 [0082]-[0083], health heart beat information indicating one or more health check messages);
determining that the node has regained functionality after a failure in the node, which
caused a lost connection with the one or more user equipment devices and the one or more network sessions of the one or more user equipment devices being transferred to the one or more other nodes (Fig.1-2 [0044]-[0045][0055], detecting/determining that the node has recovered/ regained functionality after a rapid failure in the node and, which caused a fault i.e., lost connection with the one or more mobile devices 13 and the one or more multimedia network sessions of the one or more mobile devices 13 being forwarded/transferred to the one or more other nodes and Fig.13 [0099], B2BUA1 fails and the one or more mobile stations 13 has lost their connection to the RAN base station node after a failure in the node); and
based on a determination that the node has regained functionailty after the failure in the
node (Fig.1 [0044]-[0045], recovery from failure in the node):
transmitting, at least one additional health check message to the one or more other
nodes (Fig.1-2 [0044]-[0046], transmitting SIP traffic signaling/additional health check message to the one or more SIP servers 43 or 53 via various SIP servers),
the at least one additional health check message indicating that the node has regained functionality following the failure in the node (Fig.11 [0095]-[0096], the SIP traffic signaling/additional health check message indicating that the B2BUA1 has recovered/regained e.g., reroute decision functionality following the detected failure in the B2BUA1 node and Fig.13 [0099], resuming SIP peering session with remote SIP Proxy); and
causing the one or more network sessions with the one or more user equipment
devices to be transferred back to the node (Fig.1 [0009][0043]-[0044], causing the one or more multimedia network sessions of the one or more mobile devices 13 to be forwarded/transferred back to the B2BUA1 node).
Even though Kakadia discloses wherein transmitting, at least one additional health check message to the one or more other nodes, the at least one additional health check message indicating that the node has regained functionality following the failure in the node, in the same field of endeavor, Shukla teaches wherein transmitting, at least one additional health check message to the one or more other nodes (Fig.1-2&4 [0045], at block 430 communicating the active SIP session/ health check messages to the SIP server/the respective foreign node based on a session ID),
the at least one additional health check message indicating that the node has regained functionality following the failure in the node (Fig.1-2&4-5 [0046]-[0047], the active session information message indicating that the SIP server is, at block 440 re-establishing/resuming the failover management of the one or more multimedia network sessions with the one or more user agents/user equipment devices).
Therefore, it would have been obvious to one with ordinary skill in the art before the effective filing date of the claimed invention was made to provide to have modified Kakadia to incorporate the teaching of Shukla in order to achieve media identification and negotiation.
It would have been beneficial to use the failover management system which provides the active session ID and the peer SIP server may access the active session information from the active session data store. The failover management system
may continue to re-establish sessions on one or more peer SIP servers from the unavailable SIP server as taught by Shukla to have incorporated in the system of Kakadia to provide services for multimedia communication sessions over a network connection. (Shukla, Fig.1 [0010], Fig.1-2&4 [0044]-[0046] and Fig.5 [0047])
Even though Kakadia and Shukla discloses wherein transmitting, at least one additional health check message to the one or more other nodes, the at least one additional health check message indicating that the node has regained functionality following the failure in the node, in the same field of endeavor, Hua teaches wherein
based on a determination that the node has regained functionailty after the failure in the
node (Fig.1-2 [0040], at step 208 based on the determination that the primary application server is available/ recovery from failure in the node and Fig.4 [0047], the primary application server 330 recovers):
transmitting, at least one additional health check message to the one or more other
nodes (Fig.1-2 [0042]-[0043], at step 210 transmitting a notification of heartbeat signaling to presence server/the respective other node, communication with the serving network element that the primary application server has become available and Fig.4 [0048], presence server 350 is identifying the application server 330 responds of recovering based on its SIP address in the SIP PUBLISH request/additional health check messages are received from the application server 330 with a SIP 200 OK); and causing the one or more network sessions with the one or more user equipment
devices to be transferred back to the node (Fig.1-2 [0043], at step 212, switch back to the primary application server/ resuming management of the one or more network sessions with the one or more user equipment devices to provide the service and Fig.4 [0048], switches back to the application server 330 by sending SIP requests for the service again available at the application server 330 instead of application server 340 with the SIP 200 OK/reestablish communication).
Therefore, it would have been obvious to one with ordinary skill in the art before the effective filing date of the claimed invention was made to provide to have modified Kakadia and Shukla to incorporate the teaching of Hua in order to provide various voice and data services.
It would have been beneficial to use serving network element 130 which receives the notification in step 210, and switches back to primary application server 140 as taught by Hua to have incorporated in the system of Kakadia and Shukla to provide a service for a session. (Hua, Fig.1-2 [0037], Fig.1-2 [0040], Fig.1-2 [0042]-[0043], Fig.4 [0047] and Fig.4 [0048])
