What is a patent?
A patent is a deal between an inventor and the government — a 20-year monopoly in exchange for public disclosure. Most patents that get litigated would not survive serious scrutiny.
The first 30 days after a patent infringement complaint
Most defendants spend the first 30 days reacting. The defendants who do well spend it sequencing — because every move you make in month one shapes the budget, leverage, and exit options for the next two years.
Patent term and expiration
Patents don't last forever. They don't even reliably last 20 years. The expiration date that actually matters depends on the earliest filing date, the maintenance schedule, and any USPTO or FDA delays the patent owner can claim back.
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.
The Patent Scam (2017): a documentary on the patent troll industry
Most people learn about patent trolls only when they get sued by one. The Patent Scam does the work of making the problem concrete before that happens.
