Background
SRI International, a nonprofit research institute, owned patents covering network intrusion detection and monitoring technology — specifically, systems for detecting and analyzing malicious network traffic. SRI sued Cisco Systems, alleging that Cisco’s network security products infringed these cybersecurity patents. After a full trial, a jury found infringement and awarded SRI approximately $23.7 million in compensatory damages based on a 3.5% reasonable royalty.
The district court subsequently doubled the damages award to about $47 million under 35 U.S.C. § 284, which allows enhanced damages up to three times the compensatory award in cases of willful or egregious infringement. The court cited Cisco’s aggressive litigation conduct, its status as the world’s largest networking company, and its evident disdain for SRI and its patent licensing business model. Cisco appealed, arguing that the jury’s willfulness finding and the enhanced damages award were both improper.
The Court’s Holding
The Federal Circuit affirmed in part and reinstated the enhanced damages award. On the willfulness question, the court clarified that, following the Supreme Court’s 2016 decision in Halo Electronics v. Pulse Electronics, willful infringement requires “no more than deliberate or intentional infringement.” Courts may not apply a heightened standard for willfulness — the jury need only find that the defendant knew of the patent and intentionally committed the infringing acts. In this case, the evidence supported the jury’s finding that Cisco acted willfully.
On enhanced damages, the court drew a distinction: while willful infringement is the threshold inquiry, enhanced damages are reserved for more egregious conduct — “wanton, malicious, and bad-faith behavior.” But the district court’s findings about Cisco’s aggressive litigation behavior, its failure to take the patents seriously, and its institutional indifference to SRI’s rights provided adequate support for the doubling of the damages award. The court also affirmed the award of attorney’s fees.
Key Takeaways
- Willful patent infringement under Halo requires only deliberate or intentional infringement — there is no heightened intent standard, and courts cannot require proof of egregious conduct just to get to the willfulness finding.
- Enhanced damages (up to 3x) are a separate analysis from willfulness and are reserved for truly egregious behavior — but litigation misconduct, corporate disdain for IP rights, and aggressive defense strategies are all valid factors supporting enhancement.
- Induced infringement can support a willfulness finding: if a party actively induces customers to use products in an infringing manner, that conduct can underpin both the infringement verdict and a finding of willfulness.
- The Federal Circuit will scrutinize enhanced damages rulings carefully but will defer to district courts’ factual findings on litigation conduct.
Why It Matters
This decision has significant practical implications for patent defendants, particularly large technology companies. In the post-Halo world, there is no safe harbor requiring a defendant to have had a formed opinion from counsel that it wasn’t infringing before being found willful. The SRI v. Cisco decision reinforces that any company aware of a competitor’s patents faces real exposure: if it proceeds to infringe without a reasonable defense, a jury can find willfulness, and a court can enhance damages based on litigation behavior alone.
For patent holders, the case signals that enhanced damages are not merely theoretical. Courts will look at the totality of the defendant’s conduct — including how aggressively it fought the case, whether it showed good-faith engagement with the plaintiff’s IP, and whether it treated the dispute as a nuisance rather than a serious legal matter. Cisco’s litigation posture in this case — fighting every issue hard, losing on summary judgment, and continuing to trial — cost it an extra $23 million in enhanced damages.
