What to do if you get a patent demand letter
A patent demand letter is a request for money, not a court order. The plaintiff's leverage is your fear; preparation removes it.
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.
Joint defense groups: economics, formation, and the privilege framework
An NPE sues twenty defendants on one patent. Solo, each faces $3-5M in defense costs. Pooled into a joint defense group, the per-defendant number drops to $200-500K. The economics only work if the privilege framework is set up correctly.
District court vs. PTAB: where to fight a patent challenge
Every defendant who actually fights a patent ends up choosing — sometimes implicitly — between district court invalidity, PTAB IPR, or both in parallel. The trade-offs are not symmetric; the choice often determines the case.
Octane Fitness v. ICON Health & Fitness (2014)
Octane Fitness rejected the rigid Brooks Furniture test and restored district-court discretion over fee awards. Together with its companion Highmark, it gave defendants the most realistic post-trial recovery path the modern patent system has produced.
