Appellee, Micro-Magnetic Industries, Inc., sued appellants, Ardac, Inc. and its subsidiaries, for infringement of United States Patent No. 2,964,641, referred to as the ‘Selgin II patent.

The suit upon the Selgin II invention was tried before the court which found that the Ardac machine infringed Claims 1, 4 and 5 of United States Patent No. 2,964,641. The court enjoined the defendants from infringing Claims 1, 4 and 5 without a license from Micro-Magnetic, and awarded damages for infringement based upon four percent of the price of Ardae’s machine. Ardac appeals from that judgment.

Having reviewed the record, we have concluded that the trial court’s findings of fact are clearly supported by the evidence. We agree with the trial judge’s opinion and affirm the case on the authority thereof. That opinion is reported at 372 F.Supp. 477 (D.C. 1972).

Affirmed.
