Lumen View v. FindTheBest (2013-2016): when a defendant fought back, the troll paid
Same patent. Same plaintiff playbook. Different outcome — because the defendant had the resources and the will to fight. Most don't. That's the asymmetry this site is built to fix.
Bilski v. Kappos (2010)
Machine-or-transformation isn't the only § 101 test, business-method patents survived as a category, and the specific Bilski hedging method was unpatentable. The trio of Bilski, Mayo, and Alice gave defendants the modern § 101 motion.

AI prior art search tools: a 2026 buyer's guide for defendants
AI doesn't replace a patent attorney's judgment. It does replace the search step that used to cost $20,000 and take three weeks.
