Independent Wireless Telegraph Co. v. Radio Corp. of America

Background

A large technology company that held an exclusive license to use and sell certain radio inventions sued a competitor it said was using the same equipment to carry on commercial ship‑to‑shore radio service for pay. The license originally came from the inventor’s company, which later reserved ownership of the patents. The licensee put the patent owner’s name on the complaint as a co‑plaintiff even though the owner refused to join and was beyond the court’s reach. A lower court dismissed the suit but an appeals court allowed the case to proceed; the appeal reached this Court.

Reasoning

The Court addressed whether an exclusive licensee can make the patent owner a co‑plaintiff without consent when the owner is outside the court’s jurisdiction. The justices reviewed earlier laws and cases saying that, ordinarily, suits to stop infringement in equity must include the patent owner. The Court concluded equity can, in order to prevent a failure of justice, let an exclusive licensee join the owner as a plaintiff after requesting the owner to join. The Court emphasized the owner’s implied duty to permit use of the owner’s name to protect the licensee’s monopoly and likened the remedy to historical practice at law where an assignee could sue in the assignor’s name.

Real world impact

The decision lets exclusive license holders pursue injunctions, profit accounting, and damages even when the patent owner is hostile or out of reach, provided the owner was asked to join. It protects licensees’ practical ability to enforce their exclusive rights and prevents infringers from escaping a single, comprehensive suit.
