Praluent will continue to be available in European countries where it is approved for use and for sale.This affirms that Amgen’s asserted claims against Sanofi in Europe are invalid. The EPO decision follows a ruling in Sanofi and Regeneron’s favor in August 2019 by the U.S. District Court for the District of Delaware which found as a matter of law that certain of Amgen’s asserted patent claims for antibodies targeting PCSK9 are invalid based on lack of enablement.
