We've taken the same approach. Suing first. The problem is that all you've done is declare venue. You'll still need to settle because not settling will cost you at least $1mm to fight this in court. And if you win, and find yourself not to be infringing, they can just find another patent and start the process all over again. You'll never get your legal fees back. That's not how patent suits work. That's why it's such a scam. I'd just settle and view it as a tax on innovation while working on changing the larger patent system.
