eBay Inc. v. MercExchange (2006)
Pre-eBay, an injunction was a kill switch a patent holder could threaten. Post-eBay, the worst is monetary damages — and for an NPE that wants license fees anyway, the four-factor test usually fails on the irreparable-harm prong.
District court vs. PTAB: where to fight a patent challenge
Every defendant who actually fights a patent ends up choosing — sometimes implicitly — between district court invalidity, PTAB IPR, or both in parallel. The trade-offs are not symmetric; the choice often determines the case.
What it costs to get a patent (AIPLA Economic Survey)
A US utility patent costs a median of $8,000-$12,000 in attorney fees to draft and file, depending on the technology — before USPTO fees, before drawings, and before the first office action. Here's the full bill, and why it's a rounding error next to enforcing the thing.
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.
