Searching & reading may be all free at www.uspto.gov but no self-respecting patent searcher uses it for anything more than a cursory inquiry. The pto site is slow and clunky and can only display one page of a patent (or patent publication) at a time. Google patents is way better, but incomplete, so if the one reference that really makes a difference to you is one Google don't have in their archive, you're SOL.
The pto does offer an extraordinarily great searching tool called EAST. It's also free, and it's a purpose-built app for patent searching. One you learn how to use it you'll be able to bang through hundreds of relevant patents an hour (depending on the type of art you're searching for). You can also search international patents. It's the ne plus ultra of patent searching tools.
Oh, the catch. You have to travel to the patent office's public search room in Alexandria, VA to use it.
