IPR estoppel: the trade-off behind the cheapest invalidity tool
File your strongest art, file it well — or don't file at all if your strongest grounds aren't patents and publications. Estoppel is what makes IPR powerful for the system and dangerous for the defendant who underprepares.
The America Invents Act (2011)
The AIA was the structural reform that gave defendants modern tools — IPR, broader prior art, joinder limits. The unfinished work is cost: AIA didn't make defense free, it made defense possible.
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.
How patent trolls operate (and why the business model works)
A junk patent generates settlement income exactly the same way as a strong one, because nobody pays $1M to test a $200k demand. The mechanics matter because the failure modes — what makes assertion campaigns expensive or risky for the troll — are exactly where defendants find leverage.
Non-Practicing Entity (NPE) lawsuit defense: a defendant's playbook
Defending an NPE suit is different from defending a competitor's suit. The asymmetries cut both ways — and the right plays exploit the ones that favor the defendant.
