Patent troll insurance skirts the line of being just as bad as patent trolls themselves: "Pay us some money and maybe you won't get hit by patent trolls." It's a great idea, but when I look at it closer, it looks pretty similar to trolling: "Pay us a little bit of money and we'll go away." It's not quite that bad, because it adds on "...and we'll make other people go away," but it's still interestingly close.

One additional thought: anyone who buys patent troll insurance instantly becomes a highly-cooperative target. Why fight it? Why ignore it? Just send the contact info for your insurance company, and let them pay it.
