after stating the facts, delivered the opinion of the court. The contract, upon which suit was brought, obligated the Brake Beam Company to pay an indivisible sum, ten thous- and dollars. The consideration was the conveyance to the Brake Beam Company of certain inventions patented and to be patented; as also an agreement, that during the period to be covered by certain of the letters patent, Pungs would not engage in the brake beam business in any place within the United States, or be connected with any company engaged in such business. The contract does not disclose how much of the consideration was for the patents, or how much for the agreement to remain out of business. On the face of the contract, either consideration, assuming that they were both lawful, would sustain the contract, and entitle Pungs to a recovery.
It is not argued that the consideration, so far as it is embodied in •the inventions transferred, is not lawful. Parties may lawfully assign inventions not yet patented, and even future inventions, so far as such future inventions are tributary to the inventions assigned.'
But is was insisted that the agreement embodied in the contract to remain out of the brake beam business within the United States for the time named, was an attempt to illegally restrain trade, to illegally restrict competition, and to create a monopoly; and was, therefore, an unlawful consideration; and evidence was offered tending to show that though the assignment of the inventions wás stated to be a part of the consideration, the sole real consideration, as understood between the parties at the time, was this agreement to remain out of the brake beam business. This evidence was excluded. Evidence, also, was offered tending to show that the inventions were without commercial or practical value. But independently of its probative weight on the issue whether the agreement to remain out of business was, or was not, the sole real consideration, such evidence clearly would have been immaterial.
*926The first question thus presented, is this: Is the agreement to remain out a consideration that invalidates the contract? If the contract is not thus invalidated, the entire case made by plaintiff in error fails.
It will be noted that Pungs actually transferred the patents, so that the contract in this respect was already executed; also, that the period he was to remain out of the brake beam business was just the period the transferee was to have the benefit of the patent transferred; and, further, that Pungs was at liberty, at any time during the period named, to return to the brake beam business upon refunding the ten thousand dollars paid him.
We do not look on this as a contract in restraint of trade. It binds no one to stay out of the trade. At most, it is an agreement, merely, that if Pungs renews his connection with the trade, he shall return the consideration received by him for the patents transferred. Pungs, personally, was not a manufacturer of brake beams. He was in no true sense a dealer or competitor, commercially, in that business. His .connection with the business was that of inventor chiefly; and the agreement under consideration may be considered as an incident, only, to the commercialization of his invention. Even in this he has put no mortgage on his inventive faculties. He has merely put himself where, without putting any binding restraint on his inventive faculties, or for that matter, upon his liberty as a manufacturer, he will realize, for the time being, on what he has already invented, the largest commercial return.
This is not, in our judgment, restraint of trade. The question whether a given contract is restraint of trade depends as much upon the nature of the business said to be restrained, as upon the more commonly mentioned elements of time and place. Harrison v. Glucose Refining Company, 116 Fed. 304, 53 C. C. A. 484, 58 L. R. A. 915. The nature of the contract under consideration comes plainly within the principles of that case, and of Morse, etc., Company v. Morse, 103 Mass. 73, 4 Am. Rep. 513, and other cases.
In the view thus taken of this question, the other questions raised and discussed become immaterial. The judgment of the Circuit Court is affirmed.
