In October, a Federal Circuit panel vacated a permanent injunction against Sanofi and Regeneron’s Praluent® and remanded the proceeding to the district court for a new trial on the defendants’ written description and enablement defenses.[i] The panel had held that the district court erred by (i) excluding the defendants’ evidence of written description and
