I'm bootstrapped so I don't have deep pockets.
Is there any form of insurance that can help protect my startup from getting swallowed up by trolls?
I want to emphasize again: I'm not, as far as I know, infringing any patents. I'm not looking to protect against intentional infringement (as I would never intentionally infringe).
Edit: Looks like Intellectual Property Insurance is exactly what you are looking for.
