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 (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.
Claim(s) 1, 2-4, 7-8, 9, 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over RAVISHANKAR et al. ( US 20230075345, hereinafter, RAVISHANKAR’s 345 ) in view of RAVISHANKAR et al. ( US 20230269780, hereinafter, RAVISHANKAR’s 780 ) .
Regarding to the claim 1, US 20230075345 teaches a method of an electronic apparatus transmitting a signal, the method comprising:
a routing table information including information associated with a plurality of Internet Protocol (IP) addresses ( Once the entries of the routing table are determined, the RMF 1436 uploads updated routing table information to the relevant satellites, where each satellite may receive unique routing tables similar to the examples shown in FIGS. 18A and 18B. The RMF 1436 may upload only those entries that have changed from the previous upload to minimize management plane overhead. Each satellite may have a pre-defined IP address and the RMF 1436 may then populate an IP header carrying Flow Label or DiffSery Code Point (DSCP) to the individual satellites with appropriate priority levels to upload the routing tables. Updates that are a result of a link failure may be uploaded with Flow Label and DSCP which receives the highest priority communication treatment from the RMF 1436 to the satellite of interest.) ;
generating, based on the routing table information, identification information for a predetermined IP address associated with another electronic apparatus to which a data packet is to be transmitted; and transmitting a signal including the identification information and the data packet ) [see Paragraphs 0093 & 0094];
generating (update and maintain Satellite ID for a pre-defined IP address ) , based on the routing table information, identification information (satellite IDs ) for a predetermined IP address (pre-defined IP address) associated with another electronic apparatus to which a data packet is to be transmitted [see Paragraphs 0093 & 0094]
( [0094] FIG. 20 illustrates a method for a satellite system with software defined network orchestration as described herein. The system first receives inputs from the satellites and gateways in the system (step 2010). The inputs may include satellite and gateway link status from the satellites and gateways, satellite mapping status for direct UT-UT communication and request for gateway ID for special UT as described above. The system may then determine routing tables for the satellite (step 2012). The routing tables may be determined by the RAF described above which may be located in a ground based server. The satellite tables may include next hop information for delay sensitive and delay insensitive flow types. The determined routing tables are then uploaded to the satellites (step 2014). Only updated routing tables, those containing new information, may be uploaded. Each satellite then monitors data traffic flow to determine satellite IDs where the data is to be sent (step 2016). The UTs may then load satellite IDs in a data header to send data to a desired satellite as described above (2018). Then, send data to a next hop towards the desired destination satellite based on the satellite ID in the data header using the routing tables (step 2020). Data can be sent to a different next hop depending on the flow type of data as described above and shown in FIG. 19. ) [see Paragraphs 0093 & 0094 ]
