CAFC in Amgen v. Sanofi





Appellants Sanofi, Aventisub LLC, Regeneron Pharmaceuticals
Inc., and Sanofi-Aventis U.S., LLC (collectively,
“Appellants”) appeal from a final judgment of the
district court holding U.S. Patent Nos. 8,829,165 (“’165
patent”) and 8,859,741 (“’741 patent”) not invalid and
granting a permanent injunction enjoining sales of Appellants’
Praluent® alirocumab (“Praluent”).1 In particular,
Appellants argue that the district court improperly excluded
evidence regarding written description and enablement,
improperly instructed the jury on written
description, improperly denied Appellants’ motion seeking
JMOL of no written description and no enablement,
improperly granted Appellees’ motion seeking JMOL of
non-obviousness, and improperly issued the permanent
injunction. Appellants’ Br. 1. Because we conclude that
the district court (i) erred by excluding Appellants’ evidence
regarding written description and enablement, and
(ii) improperly instructed the jury on written description,
we reverse-in-part and remand for a new trial on written
description and enablement. We also conclude that
Appellants are not entitled to JMOL of no written description
and no enablement. We affirm the district
court’s grant of Appellees’ JMOL of non-obviousness.
Finally, we vacate the district court’s permanent injunction.
