The Federal Circuit heard the case of Sanofi v. Watson Labs.. Sanofi is the owner of two patents claiming compositions and uses of the cardiovascular drug dronedarone. The ‘167 patent claims methods of reducing cardiovascular hospitalization by administering dronedarone to patients meeting specific conditions that mirror those of a clinical study conducted by Sanofi between 2005 and 2008 (“ATHENA”). The court held that the asserted claims do not exclude compositions containing polysorbate surfactants. Watson and Sandoz appealed; the Federal Circuit affirmed the judgment in full.
