There are a few companies out there that seem to offer insurance packages for small(er) players in a market that want to be able to defend patents that are likely to be infringed.
On the face of it, this makes good sense (given reasonable premiums and terms), but there seem to be very few providers of this kind of insurance product, and very few stories online that tell of successes/failures which would give a prospective buyer more insight.
Has anyone here had experience dealing with some of the providers in this market? Has anyone used this before, and if so was it money well spent?
