Halbert, J.

This action has been brought by Charles F. Hansen, (hereinafter referred to as plaintiff) as owner of United States Letters Patent Number 2,552,673, issued May 15, 1951, against Colliver and Fuller (hereinafter referred to as defendants), jurisdiction being founded upon Title 28 U.S.C.A. § 1338 (a). It is alleged in the complaint that a device, constructed and used commercially by defendants, infringes the Hansen patent, and plaintiff, having waived an accounting for damages, prays solely for injunctive relief. Defendants, by their answer, deny any infringement and contend that, in any event, the Hansen patent has been anticipated, and so is void. In addition, the defendants counterclaimed for damages alleged to have resulted from notices sent by plaintiff to defendants’ customers alleging infringement of the Hansen patent by the customers, which resulted in defendants being unable to find purchasers for the product of their device.
