Claim Rejections - 35 USC § 102
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)(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, 4-5, 7-8, 11-12, 14-16, and 19-20 are rejected under 35 U.S.C. 102(a)(2) as being unpatentable over RFC8210: The Resource Public Key Infrastructure (RPKI) to Router Protocol, version 1, hereinafter referred to as “RFC8210”.
Regarding claim 1, RFC8210 disclosed a communication method implemented by a network device, wherein the communication method comprises:
sending a data request message to a resource public key infrastructure (RPKI) server to request the RPKI server to send first data corresponding to a first data type of multiple data types (RFC8210 disclosed on page 21, section 8.1 the typical sequence of PDU transmission for a “start or restart” conversation between a router and a RPKI cache, where the router sends a “Reset Query” or “Serial Query” to the cache. Said “Reset Query” or “Serial Query” anticipates the data request message in the claim), wherein the data request message comprises an identifier of the first data type (RFC8210 disclosed on page 12, section 5.4 that the Reset Query contains a PDU type field. This PDU type field anticipates the “first data type” in the claim. See RFC8210, section 5.1 for more information on the PDU Type field); and
receiving the first data from the RPKI server in response to the data request message (RFC8210 disclosed on page 21, section 8.1 that the Router receives Cache Response and Payload PDU from the RPKI Cache server in response to its Query).
Claim 8 lists substantially the same elements as claim 1 in method form, but from the perspective of an RPKI server instead of a router. Therefore, the rejection rationale for claim 1 applies equally as well to claim 8.
Claim 16 lists substantially the same elements as claim 1 in apparatus form rather than method form. Therefore, the rejection rationale for claim 1 applies equally as well to claim 16.
Regarding claims 4, 11 and 19, RFC8210 disclosed the subject matter of claims 1, 8 and 16 respectively.
RFC8210 further disclosed wherein the data request message is a specific data reset query message, and wherein the specific data reset query message, further requests the RPKI server to send all data corresponding to the first data type, and wherein all the data includes the first data (RFC8210, pages 21-23, section 8.1-8.3, “Reset Query”).
Regarding claims 5, 12 and 20, RFC8210 disclosed the subject matter of claims 1, 8 and 16 respectively.
RFC8210 further disclosed wherein the data request message is a specific data serial number query message, and wherein the specific data serial number query message, requests the RPKI server to send updated data corresponding to the first data type (RFC8210, pages 21-23, section 8.1-8.3, “Serial Query”).
Regarding claims 7 and 15, RFC8210 disclosed the subject matter of claims 1 and 8 respectively.
RFC8210 further disclosed wherein the multiple data types comprise at least two of an Internet Protocol version 4 (IPv4) prefix, an Internet Protocol version 6 (IPv6) prefix, autonomous system provider authorization, or a router public key (RFC8210, pages 7-8, section 5.1, “PDU Type”, e.g. IPv4 Prefix or IPv6 Prefix; page 9, “Subject Public Key Info”).
Regarding claim 14, RFC8210 disclosed the method of claim 8.
RFC8210 further disclosed sending a specific data notification message to the network device for notifying the network device that the first data is updated, that the RPKI server acknowledges the data request message, or that the RPKI server is unable to respond to the data request message, wherein the specific data notification message comprises the first identifier (RFC8210, page 10 section 5.2 and page 22, section 8.2, “Serial Notify”).
