An insurance company dedicated to patent trolls might have a policy of fighting every case in court. If you have the resources to back up this threat, it means patent trolls are much less likely to actually go to court.

Hence, specific insurance against patent trolls could work by effectively taking away the easy targets for patent trolls. It's a bit like home-insurance companies that offer discounts on good locks to keep out thieves. Everyone except for the criminals are better off afterwards.
