The Court of Appeal allowed Amgen's appeals in the revocation action and counterclaim for revocation concerning the PCSK9 antibody patent (Amgen v Sanofi and Regeneron). It set aside the Munich Central Division's decision revoking the patent, rejected the requests to revoke the patent in the UPC territories, and ordered Sanofi and Regeneron to bear the costs of both instances (EUR 1,375,000 each for first instance). The patent is maintained; the Court of Appeal found the claimed invention involved an inventive step.
