Actavis: Core member of the FTC team that undertook the underlying investigation and initial challenge of an alleged reverse payment patent litigation settlement agreement between the manufacturer of a testosterone replacement drug and two manufacturers of competing generic versions of the drug. On certiorari, the U.S. Supreme Court reversed the federal circuit court’s dismissal, allowing so-called reverse payment patent litigation settlement agreements to come under antitrust scrutiny.
