Switching from "first to invent" to "first to file" makes no sense to me. If you're working on something for several years and some asshat hacks your computer, copies all the data, then files the patent, why should they get credit for it? Beyond that, I don't understand how some filers seem to be able to get patents in a few months while others take YEARS to even get reviewed. Something doesn't smell right here. And then there's the patent troll problem. Why has nobody put forth legislation that requires the patent holder to also be the applier of the technology? Nobody likes campers in a MMO game. IMHO, if you own a patent, you should be required to create a real product with it and sell it in order to benefit from the patent protection.
