In re: Enhanced Sec. Research LLC, No. 13-1114 (Fed. Cir. 2014)Annotate this Case
ESR’s 236 patent, as amended, claims a computer security device and method for preventing unauthorized individuals from obtaining access to a local computer network. Its specification describes an “intelligent network security device” (INSD), capable of balancing the desire for network security against the need for network accessibility. The INSD protects a local network by: monitoring the data packets flowing into and out of the network in order to detect suspicious patterns of communications; assigning weighted values to any threatening activity it detects; and blocking communications based on their assigned weight using a firewall. A third party requested reexamination of the original patent and the PTO considered prior art. The examiner rejected certain claims as obvious. The Patent Trial and Appeal Board and the Federal Circuit affirmed.
