Usually a "vexatious litigant" is not one of these patent trolls, but some nut job who spends his days at the courthouse.

If more companies let patent trolls go to court their repeated losses would fall under the first part of California's definition, but since they settle, trolls are technically not even litigants.

Most patent trolls file in the Western District of Texas; it's a troll friendly district with a troll friendly judge. They sometimes win with garbage patents.
