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.
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.
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.
The patent litigation lifecycle
Most patent cases never reach trial. A defendant who understands the lifecycle makes better decisions about when to fight, when to settle, and when to invest in IPR — instead of overspending on whatever phase they happen to be in.
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.
