I see absolutely no problem with this. If the patent is defensible, then no amount of law firm action or monetary incentive should make any difference in removing the patent. Most software patents are probably indefensible which does already say a lot about software patents.
Calling for changes to patent law is where I don't understand what you're hoping to accomplish. If there was going to be any change, it would already have happened.
If true, that's a pretty depressing statement, however, it sounds like fallacious reasoning to me. Just because the law hasn't changed yet doesn't mean that things are doomed to stay this way forever.
So no one wants to touch on meaningful reform, because that would blow up just as many of their own patents. Even companies that claim to amass patents purely for defensive purposes have this incentive.
There's also an agency problem. To fight patents you need patent lawyers, but patent lawyers have a strong incentive to expand the volume of patent litigation. It's like asking why the NYSE doesn't implement one of the simple solutions that would stop HFT: they're getting a cut on the volume of trades, so they don't care at all how decoupled from economic reality trading becomes.
If it's a legitimate patent, it's likely to hold up, and/or be seen as too tough of a target, and so be seen as a waste of resources to go after.
Amazon's One-Click patent is a perfect example. Amazon would have developed one-click whether or not it was patentable. By granting the patent, we granted Amazon a monopoly and didn't get anything in return.
I LOVE the shorter patent idea - particularly for software patents. It wouldn't work for pharma, but that's okay.
You basically want to put out bounties for law firms to take cases against patents? What patents would they target? What adversarial setting would they defend / attack patents in? Couldn't this result in a race to the bottom about what things people want in the public domain - ie. a bunch of people petitioning to have a law firm attack Amazon's One-Click patent? Basically if someone made something desirable enough, then an efficient market would funnel enough money into trumping their patent through your concept, destroying whatever incentive the company had to make something valuable.
I could be off on what your suggesting, so i apologize.
While there are lots of flaws & advantages in the patent system, one major opinion I have is that there should be some sort of use/active-pursue requirement. Ie. you can't claim property ownership over an idea unless you're actively putting it into product / trying to figure out how. Or maybe a shorter length of the patent (ie. 5/10 years), unless you're actively pursuing it.
This would be similar to adjustments in other types of property law. Ie. a lot of property law is based on incentives to define ownership / acquisition in a means that most benefits society. For example in the old property case Brazelton, they didn't award ownership to the person who found a sunk ship & squatted on it, but rather awarded ownership to the person who came later but actually had the technology to lift it.
