The long-running patent dispute between Amgen ($AMGN) and Regeneron($REGN) and Sanofi over their competing PCSK9-inhibitors (Repatha® and Praluent®) has reached another milestone. The case also represents another milestone in the changing landscape for patents covering biologic drugs. The Amgen decision is at least the second district court decision this year that has invalidated biologic antibody patents under the doctrine of enablement.

What are the strengths and weaknesses of each party’s case?
