For the new suit.
For those of you defending this troll, I challenge you to read one of them. They are essentially just extensions of his original idea, which -- brace yourself, this will blow your mind -- is that someone could stick payment info, DRM info, and media storage on a device like a card and then it could all be portable together. He didn't actually describe novel ways to build such a card, just the idea of making a card with these things together on it.
Then he extended his brilliant idea with subsequent patent filings. To optical drives. And hard drives. And set-top boxes. And anything else he could think of. Now, because he was so brilliant, the world needs to pay him billions of dollars so that they can use his idea that was totally, totally non-obvious, amirite?
Hardcore patent troll. And shame on those of you defending him.
