Once again, Cloudflare has proven that its unusual defense against meritless claims of patent infringement effectively works to end so-called "patent trolling."

In a blog post, Cloudflare announced that its most recent victory—defeating a lawsuit filed by Sable IP and Sable Networks in 2021—was largely thanks to participants of Project Jengo. Launched in 2017, Cloudflare's program offers tens of thousands of dollars in awards to activate an army of bounty seekers and crowdsource submissions of evidence—known as "prior art"—that can be used to overcome frivolous patent claims or even invalidate patents that never should have been issued.
