The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-6, 8-11, and 16-24 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Whitmore et al. (U.S. 2002/0122394 A1).

Re claim 16, Whitmore disclose in Figures 1-18 network management software to update the routing table to change a network setting of the communication device (e.g. paragraphs [0076-0078 and 0110]); an operating system to detect a change in the network setting performed by the network management software and provide a notification of the change (e.g. paragraphs [0068 and 0112]); and setting correction software being application software to update the routing table to correct the network setting (e.g. paragraphs [0076-0078 and 0110] with updating the routing records in response to correct routing information), the setting correction software being the table management means, wherein when the setting correction software receives a notification of a change in the network setting from the operating system and the routing table indicates the first path and the second path each as the default route, the setting correction software registers the first record with the routing table and updates the routing table to indicate the second path as the default route (e.g. Figures 5 and 13). Re claim 17, Whitmore disclose in Figures 1-18 the setting correction software registers, with a recovery file stored in the memory storage means, information indicating the first record and information indicating the second path as the default route (e.g. paragraphs [0075-0077]), and when the network management software deletes the first record from the routing table and updates the routing table to indicate the first path and the second path each as the default route, the setting correction software registers the first record with the routing table and updates the routing table to indicate the second path as the default route based on the recovery file (e.g. paragraphs [0016, 0024, 0076-0078] wherein it updates the routing records).

Re claim 22, it is a network system claim having similar limitations cited in claim 1. Thus, claim 22 is also rejected under the same rationale as cited in the rejection of claim 1. Re claim 23, it is a method claim having similar limitations cited in claim 1. Thus, claim 23 is also rejected under the same rationale as cited in the rejection of claim 1. In addition, Whitmore disclose in Figures 1-18 updating the routing table to indicate a second path as a default route selectively from a first path through the first communication network and the second path through the second communication network (e.g. paragraphs [0016, 0024, 0076-0078] wherein it updates the routing records); communicating with the first communication device through the first communication network based on the first record registered with the routing table (e.g. Figures 1 and 5 and 13 with latest/updated routing table); and communicating with a second communication device through the second communication network based on the default route indicated by the routing table, the second communication device being connected to the communication device through the second communication network (e.g. abstract and paragraphs [0034-0035, 0087-0088, and 0112]). Re claim 24, it is a medium claim having similar limitations cited in claim 1. Thus, claim 24 is also rejected under the same rationale as cited in the rejection of claim 1. 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, 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 7 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over Whitmore et al. (U.S. 2002/0122394 A1) in view of Morris (U.S. 2019/0149449 A1). Re claim 7, Whitmore to disclose in Figures 1-18 the processing circuitry table management means registers a fourth record with the routing table, and the fourth record includes, as the destination network ID, an IP address associating the IP address of the first communication device of the first communication device, includes the full-bit subnet mask as the subnet mask, and includes the IP address of the first gateway as the gateway IP address (e.g. tables in Figures 5 and 13), the communication target information includes the identification information of the first communication adapter, the processing circuitry accesses communication device further comprises second address identification means for accessing the first server and identifying identifies the IP address of the first communication device using the hostname of the first communication device included in the communication target information (e.g. as part of DNS server as seen in Morris’ teaching below), and the processing circuitry table management means registers the first record with the routing table, and the first record includes, as the destination network ID, the identified IP address of the first communication device identified by the second address identification means, and includes, as the gateway IP address, the IP address of the first gateway identified using the identification information of the first communication adapter included in the communication target information (e.g. Figures 1 and 5 and paragraphs [0076-0077 and 0102-0104]). Whitmore fails to disclose the DNS server associated with DNS IP address and DNS hostname wherein the DNS is domain name system. However, these limitations are typical in network communication with DNS architecture as seen in Morris. Morris discloses in Figures 1-139 the DNS server associated with DNS IP address and DNS hostname wherein the DNS is domain name system (e.g. abstract and paragraphs [0305-0306] for dissolving hostname such as URL). Therefore, it would have been obvious to a person having ordinary skill in the art before the effective filing date of claimed invention to add the DNS server associated with DNS IP address and DNS hostname wherein the DNS is domain name system as seen in Morris’ invention into Whitemore’s invention because it would enable to enhance communication in network utilizing the hostnames instead. Re claim 12, it is a device claim having similar limitations cited in claim 7. Thus, claim 12 is also rejected under the same rationale as cited in the rejection of claim 7. Allowable Subject Matter Claims 13-15 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US-9041956-B2 US-11252183-B US-20200175195-A1 US-20190149449-A1 US-20150188808-A1 US-20130343387-A1 US-20130110995-A1 US-20090168787-A1 US-20020122394-A1 Any inquiry concerning this communication or earlier communications from the examiner should be directed to PHUOC H NGUYEN whose telephone number is (571)272-3919.
