SRI International, Inc. v. Cisco Systems, Inc.

While the interconnectivity of computer networks facilitates access for authorized users, it also increases a network’s susceptibility to attacks from hackers, malware, and other security threats. Some of these security threats can only be detected with information from multiple sources. SRI developed the inventions claimed in patents titled “Network Surveillance” and “Hierarchical Event Monitoring and Analysis.” SRI had performed considerable research and development on network intrusion detection before filing the patents-in-suit. In an infringement suit, the district court denied Cisco’s motion for summary judgment of patent ineligibility, construed the claim term “network traffic data,” granted summary judgment of no anticipation, and denied judgment as a matter of law of no willful infringement. The court awarded enhanced damages, attorneys’ fees, and ongoing royalties. The Federal Circuit affirmed the denial of summary judgment of ineligibility, adopted the claim construction, and affirmed summary judgment of no anticipation but vacated and remanded the denial of judgment as a matter of law of no willful infringement, and therefore vacated the enhancement of damages. The court also vacated the award of attorneys’ fees and remanded for recalculation and affirmed the award of ongoing royalties on post-verdict sales of products that were actually found to infringe or are not colorably different.
