Issued patent != patent pending. Patent pending has no legal standing and is non-defensible. It just means something was submitted and may or may not be approved sometime in the future (possibly years from now). Talk to a lawyer, but I'm pretty sure they'll tell you to ignore him. If the troll in question hasn't actually submitted a patent you could sue for damages.

If you were hit with an actual patent claim, the first question you ask is what is the patent # and which specific claims are they referencing. Then go back to any referenced patents and see if the claims are unique to the new patent. Of the unique claims then you can make a case if your product infringes or not.

As I understand it, defending a patent suit is not cheap even if you're completely in the right.
