On January 5, 2017, the District of Delaware issued its long-awaited decision in the patent dispute pending between Amgen and Regeneron wherein the Court granted Amgen’s request for a permanent injunction against Regeneron’s new PCSK9-inhibitor cholesterol drug. Both Amgen and Regeneron each independently spent billions of dollars over the past decade-plus developing a new class of cholesterol drug. The drug itself comprises an antibody that binds to PCSK9 proteins… Whereas Regeneron managed to be the first to market, Amgen succeeded in getting to the Patent Office first. Amgen originally sued Regeneron, along with Sanofi, its European partner, in October 2014. Amgen asserted three patents directed to antibodies that bind to PCSK9. Over the next month, Amgen commenced additional lawsuits as new patents issued from the Patent Office. The cases were eventually consolidated, but Amgen eventually went to trial against Regeneron on only two of the originally asserted patents.
