Thе complainant in this suit seeks to recover of the defendants certain license fees for the use of a machine known as the “McKay Sewing-Machine.” The machine is for uniting the solеs of boots and shoes to. their vamps or uppers, and embodies in its construction several patents. The lease bears date January 23,1878, and it terminated September 6, 1887, or at the еxpiration of the youngest patent used in the machine. McKay v. Mace, 23 Fed. Rep. 76. The plaintiff association issued many licenses of the same kind as that taken by the defendants. Upon the taking out of a license a certain sum of money was paid, either by way of expenses for putting up the machine, or on account of its cost. By the terms of the license the licensee was to pay the sum of 10 cents for each and every pair of shoes made by aid of the machine, or, instead thereof, he might purchase and affix a certain stamp to each pair of shoes. The present machine was originally licensed by the plaintiff to Prichard, Smith & Co. In January, 1878, a new firm was formed, comprising the present defendants, and subsequently the original lease was surrendered to the plaintiff, and a new one issued to the new firm. For this license, and some other machinery, the defendants paid $425 to the old firm.
Several defenses were set up in the answer, but at the present hearing the main ground relied upon is the eviction of the defendants by the acts of the plaintiff. The principal act complained of as constituting an eviction is as follows: In the spring of 1881, for certain reasons which it is unnecessary to enter into, the McKay association, represented by the plaintiff, determined after August 14th of that year, tо exact no more royalties for their machines, but to sell them to their licensees, or to strangers, for a gross sum of $350 for a new and $250 for an old machine, Which were about the same amounts the original lessees paid for the expenses incidental to setting up their machines. This was called a commutation of royalties. This course of action was determined upon after consultation between the plaintiff association and many of the leading manufacturers who had licenses, and the proposition has been accepted by mоst of the licensees. It is contended by the defendants that
I do not understand that the doctrine of eviction, as between licensor and licensee, has ever been pressed so far as this, and I find no ease which supports thе position of the defendants. It has been held that where a patent has been repealed, or where a licensee is enjoined from acting under a license at the suit of the owner of a senior patent, there is an eviction. Walk.
