NEW YORK (Legal Newsline) – The U.S. Court of Appeals for the Second Circuit has ruled that the defendants in a class action lawsuit involving Adderall XR did not violate the Sherman Act when it supplied the plaintiffs’ competitors with an unbranded version of the drug.

The plaintiffs, who are wholesale dealers in pharmaceutical products including Adderall XR, brought the class action alleging that the defendants violated the anti‐monopolization provision of the Sherman Act by breaching defendantsʹ contracts to supply two of their competitors — who in turn supply the plaintiffs — with an unbranded version of the defendantsʹ patented drug for resale under the competitorsʹ own labels, according to the June 9 opinion.
