Hooray for him.

Patent trolls have a business model, which he's disrupted:

1) buy a patent, the broader and better-tested the better

2) start threatening the easy marks; the ones who roll over and write you a check right away.

  Their trick is to ask for a settlement small enough to say "hey, it'll cost you more than that for attorney's fees!"

3) use that money to threaten the harder targets: the ones who will fight back. Those people get asked for much larger sums.

4) maybe actually go to trial with a very big target, one that'll get dinged for a 9-figure judgment if the troll wins. In the Eastern District of Texas, juries tend to do that.

Researching the validity of a patent does not require $400/hour attorneys. Anyone with a basic knowledge of patent law and computer science can do it. (And no, I'm not advertising for myself. I'm retired.) Do you think those expensive attorneys do it themselves? It is to laugh -- they assign it to a junior who knows technology.
