der an account to him respecting the same, the question arises upon this complaint whether the subject of the appropriation and use constituted property or property rights of the plaintiff.
The plaiiitiff does not allege that he was the exclusive possessor of the system. His letter to the defendant instances several companies which have used it to advantage, and states that “ underlying the whole system is a common sense plan of advertising.” Its use seems to be its disclosure. He does not. complain of the use that the defendant has made of it, but seeks to recover for it as if defendant had used his property. His case is unlike those in which the injunctive process of the court is sought to restrain the disclosure of a secret, or the publication of a letter, which may prove injurious to business or character.
Nor is his case like that of one who writes a tale or treatise, or play, or composes a piece of music, or paints a picture, or makes an inventionin such cases there is a production which can, by multiplying copies, be put to marketable use and its exclusive ownership be easily preserved and protected. Whoever infringes takes benefits or profits which otherwise would naturally come to the producer. Here the defendant has taken from the plaintiff no profits nor diverted them from him.
Without denying that there may be property in an idea, 01-trade secret or system, it is obvious that its originator or proprietor must himself protect it from escape or disclosure. If it cannot be sold or negotiated or used without a disclosure, it. would seem proper that some contract should guard or regulate the disclosure, otherwise it must follow the law of ideas- and become the acquisition of whoever receives it. (Peabody v. Norfolk, 98 Mass. 452.)
The allegation of the complaint that the defendant disclosed the system in confidence to the defendant is vague. It does not necessarily mean that the defendant agreed not to use it; it may mean something else. Defendant is at liberty to conduct its business in its own way; it obtained a valuable hint
