Patent troll Sable pays up, dedicates all its patents to the public!

This post details Cloudflare's successful legal defense and subsequent victory against patent troll Sable IP and Sable Networks. It highlights the technical arguments presented during the trial, specifically focusing on why Cloudflare's Magic Transit and Argo for Packets products do not infringe on Sable's patent claims. Key technical points include: 1. Cloudflare's products handle packets individually, not 'flows' or 'micro-flows' as required by the patent claim. 2. Cloudflare's servers do not have 'line cards,' a specific hardware component central to the patent's claims related to old router technology. The post also discusses the invalidity of Sable's patent claim, citing prior art references (Kodialam and Cheeseman patents) that rendered the claim obvious. Furthermore, it details Cloudflare's Project Jengo initiative, which incentivizes the public to find prior art to invalidate patent troll patents, and announces the conclusion of the Sable iteration of this project.
