One was rescheduled from earlier this month for medical reasons. But the other, GlaxoSmithKline LLC v. Teva Pharmaceuticals USA, Inc., No. 18-1976, caught our eye because of how it came about procedurally. (It’s also super interesting substantively, but because we’re procedure nerds, we’re focusing on procedure today.) The case appears to represent the rare situation (first we’ve seen) where a Federal Circuit panel withdraws its own precedential opinion and asks for re-argument without public action by the en banc Court. And it provides a nice case study of how the rehearing process works at the Federal Circuit, so we thought we’d walk through it.
