1Opinion of the Court
COFFIN, Chief Judge.
Defendant, Dual Manufacturing & Engineering, Inc., appeals from a declaratory judgment in a consolidated action by three manufacturers, holding invalid its U. S. Patent No. 3,163,464 (’464) issued December 29, 1964, and from dismissal of its counterclaims seeking damages for infringement.
