A New Jersey district court recently denied a motion to dismiss Talone, et. al. v. The American Osteopathic Association, an antitrust class action. The suit alleges that the physician association violated the Sherman Act by illegally tying osteopaths’ board certification to association membership. The defendant association moved to dismiss, arguing that plaintiffs, a group of affected doctors, had failed to allege sufficient facts to demonstrate foreclosure of competition or antitrust injury. This alert reviews plaintiffs’ claims, the association’s arguments against them, and the court’s denial of the association’s motion to dismiss.
