Patent reviews: IPR, PGR, and reexamination
Suing in district court to invalidate a patent costs $3-5M and takes years. The USPTO's post-grant review system does it for $200-500k and 12-18 months. For a defendant facing a weak patent, the choice is usually obvious.
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.
Obviousness under § 103
Most patented inventions are combinations of existing ideas. The modern KSR standard makes those combinations easier to attack than they used to be.
Mayo Collaborative Services v. Prometheus Laboratories (2012)
The two-step framework defendants now recite from memory comes from Mayo, not Alice. Mayo is the often-overlooked but doctrinally essential ancestor of every modern § 101 motion.
How to obtain a patent
The USPTO process takes 2-3 years and costs $10,000-$15,000. The patent that comes out the other end is only as valuable as your willingness to spend much more enforcing it.
