IANAL, but I do work in patent/copyright/trademark law.
Antitrust counterclaims are so common, it's ridiculous. This counterclaim doesn't mean anything. Basically, antirturst counterclaims are just reflixive defensive maneuvers. What happens is that I sue you for infringement, and then you countersue me, claiming that my initial suit is knowingly baseless and that by asserting it against you, I am in violation of antiturst laws. That is, my suit against you is an unfair practice against competition; by filing it against you, I am using a baseless charge (which I know to be baseless) to stiffle competition.
Almost all of these go nowhere. That's not to say that none of them do, but really, almost all of them have no bite except to add a few more filings with the court and a little more discovery and arguments on each side.
