A company is suing Palo Alto Networks patent infringement, alleging that their proprietary technologies were used in a number of major security products and systems sold by the cybersecurity giant.

The lawsuit, filed March 12 in the Eastern District Court of Virginia by Centripetal Networks, accuses Palo Alto of violating 12 separate patents for systems or policies designed to enhance network security.

Worth noting that Centripetal has pursued – and won – patent cases against other industry titans in the past for incorporating its security innovations. Last October a judge ordered Cisco Systems to pay $1.9 billion in damages, ruling the company copied at least four of Centripetal’s patented software and network security designs in their switches, routers and firewalls. The court denied Cisco a new trial earlier this week. Centripetal also filed successful patent cases against Keysight Technologies and Ixia.

In this latest complaint, the company’s lawyers say intellectual property from the 12 patents was taken and used in numerous Palo Alto Networks security products, including its next-generation firewall, its network security management tool Panorama, its artificial intelligence security operations platform Cortex, its analysis software MineMeld and its DNS security service. Many of the innovations deal with specific methods for filtering network traffic data and rule-based network threat detection.

Most of the established details of the case thus far come from documents filed by the accuser, Centripetal Networks. Palo Alto Network’s lawyers have yet to file a response to the complaint in court, and a company spokesperson said they do not comment on pending litigation.

Centripetal’s lawyers claim that in 2016, its CEO and founder held several meetings and telephone calls with Palo Alto executives to discuss a threat intelligence partnership. Those meetings included technical overviews of Centripetal’s patented technologies, along with a non-disclosure agreement between the two parties.

“Upon executing the [agreement], Centripetal disclosed details about its proprietary patented technology and confidential details about…how Centripetal’s technical solution works, why it works, why it is effective and its strategic business strategies in the marketplace for its technical solution.”

They claim that after those details were disclosed, executives at Palo Alto Networks relayed that they were not interested in following up on the partnership opportunity. A year later, the two companies were in talks about a potential investment from Palo Alto Networks. That led to a technical meeting between Centripetal and the creator and lead developer of Minemeld to discuss potential ways to integrate their products. This also included a non-disclosure agreement between the two parties, and the Minemeld team requested and received additional technical documentation on the company’s network security technologies following the meetings.

Lawyers for Centripetal allege that Palo Alto Networks “engaged in willful infringement and egregious behavior warranting enhanced damages” by “purposefully and voluntarily plac[ing] one or more of their infringing products and/or services…into the stream of commerce,” causing irreparable harm and financial loss.

Centripetal argues that despite these and other interactions, Palo Alto made no effort to design their products in a way that would avoid infringing of their patents and exhibited “knowledge and/or willful blindness” of the company’s patented innovations. They’re asking the court for enhanced damages and an injunction preventing Palo Alto Networks from further infringing on their intellectual property.

Palo Alto Networks reported strong earnings over the past year, with CEO Nikesh Arora specifically praising the company’s AI, SASE, firewall and next generation security service business lines in recent quarterly financial reports.
