The firm possessing good will owns a precarious yet valuable claim upon its patrons, namely, the chance of their continued patronage. The persons of these subscribers, and their other wealth, are what under- lie the property right, because they are the means to the desired services to which those rights apply.

In the same way, the “custom” of a tailor or the “prac- tice” of a physician is simply the right to the chance of future patronage. A franchise in the sense of a monopoly privilege granted by a government is quite different from a street railway franchise. The object of the monopoly is to prevent cer- tain acts of certain persons. The means to that end are, in the last analysis, the persons who are constrained to refrain, and the wealth withdrawn from competition. We may similarly regard a copyright. Recalling the case of the paper trust, part of whose property was the prom- ise of a paper manufacturer not to compete, we may regard a copyright as the right to a similar refraining from or re- straining of competition.

Prevention can now be accomplished through the instrumentality of international copyright. The wealth underlying this property right is the wealth which, if employed in the specified line, would enter into
