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.
Patent law glossary
Sixty-plus patent-law terms, defined in one or two sentences each, with a link to the deeper article. The universal landing pad when an article uses a term you don't know.
What patent litigation actually costs (AIPLA Economic Survey)
It costs a few hundred dollars to file a patent complaint and a median of $1.5M-$3.2M to defend one through trial. That gap isn't a side effect of patent litigation — for a troll, it is the entire business model.
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.
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.
