1Opinion of the Court
BRENNAN, Chief Judge.
This is a patent infringement action. The validity of the patent in question is put in issue by the answer. That the plaintiff is estopped from asserting its claim of infringement was alleged both as an affirmative defense and as a counterclaim. The answer also contains a second counterclaim, which in substance alleges that the plaintiff holds its patent as a trustee for the benefit of the defendant and, therefore, should be enjoined from enforcing any rights thereunder as against the defendant, and that the patent in question should be assigned to it.
