My comment was pointing out that insurance if they have it wont be much good. In my (admittedly limited) experience if the legal costs are $500k you spend at least that much on internal time preparing, briefing and negotiating. It is a major distraction for management with the potential that things slip with their eyes on other things.

But the biggest potential loss is the lost opportunity to sell those products affected by the patents. This may come about in a settlement and not through a court order. These lost costs could represent hundreds of millions in the future.

Any insurance over will only cover the direct external expenses which will be much smaller than the total losses if the dispute is protracted.
