To plaintiffs' suit for patent infringement defendants counterclaimed upon an unrelated patent asking for an injunction and an accounting. Plaintiffs' motion to dismiss on the ground of improper venue was sustained by the district court. Defendants appealed and plaintiffs moved to dismiss on the ground that dismissal of a counterclaim was not a refusal of an injunction and therefore not appealable under Sec. 129, Judicial Code. The circuit court of appeals allowed the appeal and this decision was affirmed by the Supreme Court. General Electric Co. et al. v. Marvel Rare Metals Co. et al., 287 U.S. 430, 53 Sup. Ct. 202 (1932).
