Comment: Nice idea... Won't happen. (Score 4, Insightful) 205
FWIW, this is my personal opinion:
It would never happen. Today's purpose of patents is different from when the concept was created. The use today is to prevent a small or single owner nimble upstart from usurping the business of an incumbent elephant and potentially gutting the cash cow of it's shareholders.
The aforementioned incumbents would fight tooth and nail, with large campaign contributions and gifts, to prevent such a law from ever passing.
