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.
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.
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.
How to read a patent claim
A patent has a 50-page specification, a fancy abstract, and a row of figures. Lawyers and courts look at none of that. They look at the claims.
Cost of Inter Partes Review (IPR): a 2026 breakdown
An IPR ends most cases when the prior art is real. The all-in cost is roughly a tenth of full litigation — but only if you stage it right.
