MedImmune, Inc. v. Genentech, Inc., 127 S. Ct. 764 (2007)
A patent licensee's payment of royalties under protest did not preclude a justiciable case or controversy under U.S. Const. art. III, since licensors' threatened legal action was coercive and preserved the licensee's right under the Declaratory Judgment Act to seek a declaration that the patent was invalid, unenforceable, or not infringed.
