Cloudflare has successfully defended itself against a patent infringement lawsuit filed by Sable Networks, a company described as a 'patent troll'. The court ruled in favor of Cloudflare, and Sable agreed to pay $225,000, grant Cloudflare a royalty-free license to its entire patent portfolio, and dedicate its patents to the public. This means Sable can no longer assert its patents against other companies. The outcome is seen as a significant victory for Cloudflare and a blow to patent trolling.
