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 (i.e., changing from AIA to pre-AIA ) 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, 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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.

identifying a packet data gateway (PGW) of a home public land mobile network
(HPLMN) associated with a user equipment connected to the core network of the VPLMN (see paragraphs [0014], [0322], [0323, [0325], [0327], and [0328], the identity information may be received in a Create Session Request message or a Proxy Binding Update message. The identity information may be received from the non-3GPP access gateway 705 via a GTP interface or a PMIP interface. The AAA node 710 indicated in the identify information may be a visited-AAA server when the PGW 108 is comprised in a VPLM 100v, and it may be a home-AAA server when the PGW 108 is comprised in a HPLMN 100h);
sending, to the PGW via a general packet radio service (GPRS) tunneling protocol
(GTP) proxy, a create session request message (CSRM) having a forward indication flag set to a first value (see paragraphs [0258], and [0281], PGW 108 receives the Create Session Request message, and initiates IP-CAN session establishment (if initial attach) or modification (if handover) with the PCRF 112 if a PCC procedure is configured. The ePDG 125 sends a Create Session Request message to the PGW 108 including the Identity of the home AAA server 110 received in the final authentication answer in step 1104);

The identity information may be received in a Create Session Request message or a Proxy Binding Update message. The identity information may be a Diameter identity of the AAA node 710);
sending, to an HPLMN home subscriber server (HSS) via a mobility management entity (MME), a notify request comprising the PGW identifier as an anchor point, the anchor point corresponding to a handover operation (see paragraphs [0008], [0013], [0024], [0025], [0157], and [0166], the H-PLMN 100h comprises a Home Subscriber Server (HSS) 106, a PGW 108, an Authentication, Authorization, Accounting (AAA) server 110, a Home-Policy and Charging Rules Function (H-PCRF) 112h and Operator's IP Services 115.

In roaming scenarios, the non-3GPP access (i.e. the ePDG 125) first sends the authentication and authorization request to a AAA proxy 128 in the V-PLMN 00v which further forwards the request to a AAA server 110 in the H-PLMN 100h. The AAA server 1 110_1 sends an Update PGW Id Request message to the HSS 106. The PGW transmits, to the selected AAA node, a request message for the UE. The request message is a request for authorization of the UE to access the EPC service via the non-3GPP access network).
