In Stilz v. United States, 1925, 269 U.S. 144, 46 S.Ct. 37, 70 L.Ed. 202 the Supreme Court affirmed a judgment of the Court of Claims, 59 Ct.Cl. 21, in which it was found that the United States had not infringed the petitioner's patents. Following this litigation the petitioner sued other persons for alleged infringement in the District Court for the Southern District of New York and a decision adverse to his claims was affirmed by the Circuit Court of Appeals for the Second Circuit in Stilz v. Babcock Wilcox Co., 1924, 5 F.2d 630. The next litigation was in the District Court for the Eastern District of Pennsylvania. Again the claim was infringement and again the decision was adverse to the petitioner. The District Court was affirmed by this court in Stilz v. Bethlehem Shipbuilding Corp., 3 Cir., 1928, 29 F.2d 156, certiorari denied 1929, 279 U.S. 834, 49 S.Ct. 254, 73 L.Ed. 983.
