MURRAH, Circuit Judge.

Insul-Wool Insulation Corporation, as assignee of patentee, William J. Kroop, brought these actions against Home Insulation, Inc., and Federal Insulation Company seeking an injunction and damages for an alleged infringement of its Letters Patent No. 2,166,926, for “packing and insulating material”. Upon a trial of the consolidated cases the trial court sustained the pleaded defense of invalidity on the grounds of prior knowledge and use of the patented product more than two years prior to the patentee’s application for letters patent on March 1, 1935.
