Court of Appeals for the Fourth Circuit July 23, 1963, 8932 (United States Pipe and Foundry Company v. Woodward Iron Company)

ALBERT V. BRYAN, Circuit Judge.

This patent litigation is between the owner of a pipe joint patent, appellee United States Pipe and Foundry Company, and the licensee of an allegedly infringing patent, appellant Woodward Iron Co. Thus the integrity of the latter patent is at stake. It is owned by James B. Clow & Sons, Inc., not a party to this suit.
