eBay Inc. v. MercExchange (2006)
Pre-eBay, an injunction was a kill switch a patent holder could threaten. Post-eBay, the worst is monetary damages — and for an NPE that wants license fees anyway, the four-factor test usually fails on the irreparable-harm prong.
Mayo Collaborative Services v. Prometheus Laboratories (2012)
The two-step framework defendants now recite from memory comes from Mayo, not Alice. Mayo is the often-overlooked but doctrinally essential ancestor of every modern § 101 motion.
District court vs. PTAB: where to fight a patent challenge

Non-Practicing Entity (NPE) lawsuit defense: a defendant's playbook
Defending an NPE suit is different from defending a competitor's suit. The asymmetries cut both ways — and the right plays exploit the ones that favor the defendant.
