Just a thought: I think patents do tend to favor the little guys. Coco cola has never had to patent their recipe, as it's a trade secret. I believe ASML and TSMC don't patent some of their technology, since it's a trade secret. They don't want to patent it, as that would reveal details. Also, iirc, if you can patent something that is shown to significantly improve on a previous patent, you can get a patent for that.

That's not to say that patents can't be abused—they certainly can—but it can give a smaller person leverage.
