> I've always thought that the inventors (or patent holders) should be entitled to all proceeds that their invention generates until they've been adequately compensated for the opportunity cost

that is worse than what we have now (damages were, until very recently, calculated on 25% of profit from the part of a product that violated a patent)

also, there are already stringent 'use it or lose it' provisions in most jurisdictions - they are easily avoided, and you only need a single state to become 'patent friendly' to screw it all up anyway
