I found a few insurance companies which seem to offer some cover for claims of patent infringement. Here is how they are briefly advertised:
"Patent infringement liability insurance is professional liability insurance for manufacturers, users and sellers who are accused of infringing a patent holder’s rights."
I have read somewhere else that annual premiums for this kind of insurance are in the 1000$-25000$ range.
Has any of you ever bought an insurance of such kind? what is your experience?
