All of these suggestions are a right step. The fundamental issue is that the current system is designed to issue when in doubt; without considering the cost to society from inhibiting progress by pointlessly throwing everything through the legal grinder with extra sand (in the form of a patent minefield). Ideally we'd start looking for an entirely different way to encourage innovation, and just cease issuing patents entirely. For example, patent-like systems with a more restrictive scope (not exlusive access to pretty much "any idea", but exclusive access to e.g. "medical approval"), so we don't accidentally hit every future sector with this junk. And perhaps we'd look for some system that's more self-regulating; i.e. where abuse exists rather in the form of ripping of the taxpayer, and less in the form of court cases. The justice system is so terribly inefficient and everything it touches, yet is just keeps on growing until everything is some kind of zero-sum game.
