There are firms that offer patent infringement insurance services. The cost is astronomical (7 figures per year).

I have a fair amount of experience with patent trolls.

I've seen companies sued for using facebook, where the damages are X dollars times the number of facebook followers/posts/comments they have. (So the level of risk is very hard to estimate for an insurer, because interaction numbers on the internet can spike easily)

Also, the the troll will practically _always_ offers a settlement that is roughly equivalent (or a few percent cheaper) than the legal fees to defend and win the case. -So a company has two options: Spend Y dollars to make it go away; or Spend Y*0.99 dollars and a year of wasted time to _maybe_ win. The system is setup such that Patent Trolls can't lose and companies can't really win.
