Finding prior art with free tools: Google Patents, Lens, Espacenet, and more
A serious paid prior-art search costs $5,000 to $20,000. The first 80% of what you'd find is sitting behind free tools — if you know how to drive them.
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.

Lumen View v. FindTheBest (2013-2016): when a defendant fought back, the troll paid
