"[0012]The inventor and the assignee of this patent have no intention of applying the techniques described herein offensively but instead intend to use the patent defensively to discourage patent trolls and the like from extortionist practices."

X launches a patent-trolling suit to try to get in on Y's patent. These guys launch a countersuit at X for using their patented technique, stalling the original suit. The best part is, the evidence for the countersuit is already known to the court...
Whew, that could have been bad.
