  • EpiPen Marketing, Sales Practices, and Antitrust Litigation:  The Firm is on the Plaintiffs’ Steering Committee leading a class action alleging that Pfizer and Mylan—manufacturer and distributor of the epinephrene autoinjector EpiPen, respectively—have unlawfully created and abused a monopoly for the life-saving product.  Plaintiffs seek to recover damages and overpayments from at least 2009 through the present, as well as injunctive relief under the federal antitrust laws and various state consumer protection and antitrust laws;
  • Inductors Price-Fixing Cartel Litigation and Investigation:  The firm is litigating and investigating an alleged anticompetitive conspiracy involving manufacturers of inductors, a widely-used passive electronic component.  The investigation indicates, and the complaint alleges, that inductor manufacturers unlawfully agreed to fix the price of inductors shipped or invoiced to U.S. purchasers;
