Vanda v. West-Ward: This Time, Dosage Adjustment Claims are Patent Eligible Subject Matter

The Federal Circuit’s decision in Vanda Pharmaceuticals Inc. v. West-Ward Pharmaceuticals, No. 2016-2707, addresses the complicated topic of patent eligibility in the pharmaceutical space. Much of the decision compares Vanda’s claims to those found ineligible for patent protection in the U.S. Supreme Court’s decision in Mayo Collaborative Services v. Prometheus Laboratories, 132 S. Ct. 1289 (2012). While the ultimate patentability conclusions are opposite, the claims in Vanda and Mayo are very similar, highlighting the thin—and often unpredictable—line that divides eligible and ineligible subject matter. Generic drug manufacturers must account for this unpredictability in gauging their litigation risks.
