On Thursday, April 20th, the Court of Appeals for the Federal Circuit issued a decision in Medinol Ltd. v. Cordis Corporation et. al. which vacated and remanded a lower court’s ruling that claims of patent infringement alleged by Israeli pharmaceutical firm Medinol were barred by the equitable defense of laches. The Federal Circuit’s decision comes after the U.S. Supreme Court overturned the Federal Circuit’s previous precedence on laches as an equitable defense in SCA Hygiene Products v. First Quality Baby Products, decided last year. The case was decided by a panel consisting of Circuit Judges Timothy Dyk, Jimmie Reyna and Kara Stoll.

Equitable estoppel may be appropriate for the defendant in SCA v. First Quality since the plaintiff was silent for years after the defendant asserted invalidity (possibly fulfilling the misleading conduct through inaction and reliance on that conduct). But can equitable estoppel be relied upon as a defense against a dormant plaintiff in the example illustrated above? Below, we consider the two elements of equitable estoppel that replace the unreasonable delay element of laches: misleading conduct and reliance.
