Comma.ai, a company founded by George Hotz, is being sued by Axel Nix, a patent troll, over a 15-year-old patent for an auto emergency call system. Hotz plans to fight the lawsuit and invalidate the patent, rather than settling. The patent troll has previously sued other companies in the autonomous vehicle industry, with some settling out of court. Hotz is inspired by Cloudflare's approach to dealing with patent trolls and plans to work with others to combat the issue.
