This morning, the full Federal Circuit declined to rehear en banc Amgen v. Sandoz, the first appellate decision interpreting the Biologics Price Competition and Innovation Act of 2009 (BPCIA). The decision to deny en banc review comes as something of a surprise, as the panel decision was fractured, and neither party disputed that it raised important issues of first impression. Indeed, both parties sought en banc review, albeit on different issues. In a per curiam order issued this morning, the court denied both petitions. Unless the Supreme Court (or a later en banc court) intervenes, the panel’s decision will stand as the Federal Circuit’s authoritative statement on the issues presented.
