News Intel scores key jury ruling in $3 billion patent duel with VLSI — ruling threatens prior patent verdicts

Go Intel!! I don't care who it is, I'll always support them in fights against patent trolls.

I'm not up to date on current US patent law, but it seems to me that the way to defeat most patent trolls would be to require an annual fee for each patent you want to maintain. That should make it too expensive to amass and maintain a large number of patents that aren't critical to your business. It's not a perfect scheme, since it would still mean that a patent troll could still secure and try to enforce a handful of key patents, but it'd help put a stop to the "shotgun approach" that they currently employ.
