The Federal Circuit has granted an en banc rehearing in SCA Hygiene Products v. First Quality Baby Products to revisit whether and to what extent a patent owner’s unreasonable delay in filing an infringement suit can bar recovery of money damages and/or injunctive relief. The en banc rehearing comes in the wake of the Supreme Court’s decision last term in Petrella v. Metro-Goldwyn Mayer, Inc., which held that the equitable doctrine of laches did not bar a copyright owner from recovering damages for acts of infringement that occurred within the statute of limitations for copyright actions. The Federal Circuit will now consider whether to extend the reasoning of Petrella to patent cases, potentially making it easier for plaintiffs who have delayed bringing suit to claim damages but possibly making it harder for such dilatory plaintiffs to obtain injunctive relief. The court has invited amici curiae to participate in the briefing process. Amicus briefs are due beginning in late February.
