Description

This was a complaint in which plaintiff Independent Pneumatic Tool Company prayed that the court enter a declaratory judgment that defendants Amtsberg patent 2219883, issued October 29, 1940, on an application filed June 5, 1937, and Fitch patent 2219865, issued October 29, 1940, on an application filed October 14, 1938, were invalid, and that plaintiffs "Thor Wrench" was not an infringement of either of these patents. The defendant Chicago Pneumatic Tool Company filed a counterclaim in which it asserted that its patents were valid and that plaintiffs wrenches infringed claims 6, 8, 18 and 30 of the Amtsberg patent and claim 7 of the Fitch patent. The trial judge found that neither of defendants patents disclosed any novel feature; that both Amtsberg and Fitch used old elements in the construction of their wrenches and for patentability depended upon a new combination of old elements, and that while both plaintiffs and defendants wrenches had many features in common, yet there were important differences. He held that the two patents were valid but not infringed, 96 F.Supp. 70, and both parties have appealed.
