When it comes to defeating patent trolls with crowd-sourced prior art, Cloudflare is now two-for-two after winning its latest case against Sable Networks. The Register: Sable Networks, which owns patents originally given to defunct "flow-based router" company Caspian Networks, sued Cloudflare and five other companies in 2021 alleging a whole host of violations of four patents now owned by Sable. A lot has changed since the case was filed in the US District Court for the Western District of Texas, leading to a jury verdict last week that found Cloudflare not only didn't infringe on the single patent that made it to trial, but that the final patent claim at issue was invalid as well.
