Electrical Fittings Corp. v. Thomas & Betts Co.
United States Supreme Court
307 U.S. 241 (1939)
The plaintiff brought suit on two claims of patent infringement against the defendants. The district court found that claim 1 was valid, but not infringed upon and found that claim 2 was invalid. The district court entered a decree stating that claim 1 was valid, but dismissed the suit for lack of infringement. The defendants, despite getting the case dismissed, appealed the judgment in so much as it adjudged claim 1 to be valid. The United States Court of Appeals for the Second Circuit dismissed the appeal because the defendants “had been awarded all the relief to which they were entitled.” The United States Supreme Court granted certiorari.
