Markman v. Westview Instruments, Inc. (1996)
Claim construction is exclusively the court's job. The Markman hearing is the most consequential single ruling in nearly every patent case — and a defendant's best chance to end the litigation before trial.
KSR International v. Teleflex (2007)
Pre-KSR, an obviousness rejection required explicit teaching, suggestion, or motivation in the prior art. Post-KSR, common sense, design needs, and predictable variations all do the work — and most patents don't survive.
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.
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.
Prior-art research, old way vs new way — a side-by-side comparison
Defense is expensive because reading thousands of pages of patents takes time. AI doesn't change that for the lawyer's strategic work — but the time-on-pages part collapses by orders of magnitude.
