Summary

Joseph McKenna United States v. United Shoe Machinery Company of New Jersey…

And the government has taken pains to tell us how far 'the mysteries of the shoemaker's art and the variations between different methods of making shoes' are outside of the understanding of the purchaser of them. To him, it is said, 'shoes are shoes, except as they differ in appearance, comfort, wearing qualities, and price.' But to the manufacturer distinctions multiply and to the production of a shoe a complete line of machinery is necessary. Indeed, the government makes the mystery of the art and the necessity of the instrumentalities, in part, the basis of its argument.

Joseph McKenna United States v. United Shoe Machinery Company of New Jersey…

To the attacks of the government the defendants reply that the leases are the exercise of their right as patentees and if there is monopoly in them it is the monopoly of the right. It must, indeed, be said that it is the experience of the world that the utility of an invention entices to its infringement, but it would be a perversion of things to facilitate the wrong by a sacrifice of the right in revulsion from the restraint which the right authorizes.

Joseph McKenna United States v. United Shoe Machinery Company of New Jersey…

Some of them were merely of accessorial machines; some in composition of patent troubles; some not connected with the special charge of monopoly to which the government has limited itself; some the transfer to defendants of kinds of machines not possessed by them; some of patented improvements and inventions, aiding or completing the defendants' machines, tributary therefore to their efficiency. They give a false impression by their number. They added nothing of obnoxious power to the United Company nor in any practical or large sense removed competition.
