It won't just weaken the system, it'll shift the balance of power in favour of large corporations. If I get a patent on some new invention and a huge corporation decides to ignore my patent, what recourse do I have? Risk losing tens of millions of dollars and bankrupting my company and potentially myself personally? No, I guess my best chance is to sell my patent to their huge competitor and hope they destroy each other.

Or would the threat of selling the patent give me enough leverage for a settlement? I hate the idea of having to rely on another large corporation to be my champion, as it were.
