In May 2015, the FTC settled a “pay-for-delay” suit against Cephalon for injunctive relief and $1.2 billion, which was paid into an escrow account. The FTC settlement allowed for those escrow funds to be distributed for settlement of certain related cases and government investigations. In August 2016, forty-eight states filed suit in the Eastern District of Pennsylvania against Cephalon alleging anticompetitive conduct by Cephalon to protect the profits it earned from having a patent-protected monopoly on the sale of its landmark drug, Provigil. According to the complaint, Cephalon’s conduct delayed generic versions of Provigil from entering the market for several years. The complaint alleged that as patent and regulatory barriers that prevented generic competition to Provigil neared expiration, Cephalon intentionally defrauded the Patent and Trademark Office to secure an additional patent, which a court subsequently deemed invalid and unenforceable. Before it was declared invalid, Cephalon was able to use the patent to delay generic competition for nearly six additional years by filing patent infringement lawsuits. Cephalon settled those lawsuits by paying competitors to delay sale of their generic versions of Provigil until at least April 2012. Consumers, states, and others paid millions more for Provigil than they would have had generic versions of the drug launched by early 2006, as expected. A settlement was filed with the complaint, which includes $35 million for distribution to consumers who bought Provigil.
