refuse to transfer shares of its stock to a purchaser who was a party to a conspiracy to boycott the business of the corporation and who desired to become a stockholder for the express purpose of discovering its source of supply.1

ENGLISH DECISIONS.

The English courts have for many years restrained the use or communication of trade secrets or confidential information, imparted to employees or associates in confidence or necessarily acquired by them in the course of employment, where to permit such use or disclosure would be a violation of an express or implied contract or would amount to a breach of trust.2 Persons acquiring a knowledge of such secrets, with notice of their confidential nature, have, also, been enjoined from using or disclosing them.

It was early held by the English courts that the use or betrayal of secret formulas or processes by faithless employees could be restrained by a court of equity. In 1820 Lord Chancellor Eldon granted an injunction restraining a former employee of a manufacturer of proprietary remedies from using in a rival business, or from disclosing to others, recipes surreptitiously copied from the books of his employer. In a leading English case on this subject, decided in 1851, one of the partners in a company, engaged in the manufacture of a medicinal preparation according to a secret formula, disclosed the formula to his son in violation of the terms of his partnership con

"In the case of the United States Pipe Line Co. the Standard obtained a minority of the stock and has been able to secure representation upon the directorate, so as to be familiar with the business secrets of its competitor."

And see brief for the United States in United States v. American Tobacco Co. et al. where it was urged that "one use of supply companies was to obtain through them information about the business of competitors. The Mengel Box Co., for example, was required to report monthly the number of boxes which it sold to independents, (R. II, 663.)" (On appeal from the Circuit Court of the United States for the Southern District of New York, p. 217.) See also Monarch Tobacco Works v. American Tobacco Co. et al., 165 Fed.. 774 (C. C., 1908).

2 Lord Justice Turner in Morison Moat, 9 Hare, 241, 255 (1851), said: "That the court has exercised jurisdiction in cases of this nature does not, I think, admit of any question. Different grounds have indeed been assigned for the exercise of that jurisdiction. In some cases it has been referred to property, in others to contract, and in others, again, it has been treated as founded upon trust or confidence, meaning, as I conceive, that the court fastens the obligation on the conscience of the party and enforces it against him in the same manner as it enforces against a party to whom a benefit is given the obligation of performing a promise on the faith of which the benefit has been conferred; but upon whatever grounds the jurisdiction is founded, the authorities leave no bt as to the exercise of it."

tract, with which the latter was familiar. The court held that the formula had been revealed in breach of trust and of contract, and granted an injunction restraining the party to whom it had been disclosed from selling or compounding any medicine according to the secret recipe, and from in any manner using the secret or any part thereof. Similarly where a manufacturer of disinfectants sold his business and covenanted not to disclose the secret process, nor engage in the same business for 14 years, the contract was held enforcible.2 So, also, a contract whereby an employee agreed not to use or disclose any of his employer's secret formulas, processes, or machinery for making typewriter ribbons and carbon paper, was held valid and the employee enjoined from violating it.3 In like manner, where an employee of a company was informed that its process of manufacture was secret, but on acquiring an imperfect knowledge of it entered the service of a competitor and was attempting to use the process and to secure the parts of it with which he was not familiar from the original inventor, it was held that an injunction should issue to prevent him from using the process.*

The same legal principles under which secret formulas or processes are protected have been invoked by the English courts to prevent the unfair use by competitors of other trade secrets or confidential information. Thus a company engaged in the manufacture of fire engines has been granted an injunction restraining a former employee and his new master from using a table of dimensions of its engines which the employee had made and carried away with him." But where a telegraph company in London made arrangements with individuals in Australia, described as agents of the company, for the transmission of its messages, using certain code words to indicate the names of firms or persons in Australia to whom messages were frequently sent, it was held that the Australian agents, on starting a similar business, could make use of this code, the property in it, if there was any, being in the telegraph company's patrons, not in the company. On the other hand, it has been held that the publisher of a trade directory, consisting principally of classified advertisements, could restrain former employees from using for the benefit of a rival company blocks, or cuts, and other materials made up while in

his employ and for his use. And where the Queen and Prince Albert made a number of etchings which they had not published, and others surreptitously secured them and had impressions made for their own private use, it was held that they should be enjoined from making engravings or copies of the etchings or from publishing or selling a descriptive catalogue of them.2 Likewise, where an engraver was employed to make copies of a drawing and secretly made copies for himself, which he sold in competition with the owners, it was held that the latter were entitled to an injunction to prevent the sale of the copies thus secretly made, and to damages.3

The English courts, also, hold that lists of customers or of agents are confidential, and that originals of such lists or copies thereof taken away by employees can not be used either by them or by subsequent employers. For example, where the owner of a game farm employed a manager under a contract that he would treat everything in connection with the business as confidential, it was held that the manager must return a list of his employer's customers which he took with him on setting up in business for himself, and must pay the damages resulting from his use of the list. And where an employee of a dealer in mineral waters contracted not to disclose any of the trusts, secrets, or dealings of his employer, but on leaving took with him a memorandum book containing the names and addresses of his employer's customers, the court commanded the return of the memorandum book and enjoined both the employee and his new master, who had notice of the contract, from using the same." Similarly a process server was granted an injunction restraining a former employee from making use of any copies or extracts from his register of agents, or index, or any memoranda made by the employee while in his service relating to any persons named on his register or index. And in a Canadian case it was held that lists of customers, and prospective customers, prepared by an agent for the territory assigned him, as well as a similar list for other territory, which he had purchased from another agent, were the property of the employer; but that a list of probable purchasers in all of Canada,

compiled by the agent, was his own property in which his employer had no rights.1

A Canadian court has, also, held that an employers rate of profit and his cost of production are confidential information for the disclosure of which he may recover damages. In this case former employees of a manufacturer of what was known as the "Loose-leaf Business System of Book and Account Keeping," who were promoting a competing company disclosed to others the company's rate of profit and cost of production, and the court directed an inquiry into the amount of damage resulting from the disclosure as well as from the use of patterns of sheets and records or dimensions of blank sheets, taken from the employer's place of business.2

Section 6. Appropriation of values created by competitors' expenditures.

A peculiarly subtle form of competition is disclosed in the appropriation in diverse ways of values created by a competitor's expenditures. Such a method of obtaining a rival's patronage and at the same time profiting by his pioneering in a particular business has been attempted, among other ways, by surreptitiously or openly taking information which another has collected for sale at large expense, and disposing of it in competition with the owner; by duplicating and selling another's articles, where, without the use of the original, a competing article could not be had at all, or could be produced only at great expense; by filling and selling a competitor's receptacles without entirely obliterating his name and that of his product and without any express notice to the purchaser that the receptacle did not contain the same article with which it was originally filled. The cases of this description are apparently limited in number and, while they show a tendency on the part of the courts to prevent one from dishonestly acquiring the benefit of another's investments and labor, the limits of the doctrine do not appear to be as yet well defined.

AMERICAN DECISIONS.

An illustration of the principle is found in a decision of the Supreme Court of the United States in 1905 where it was held that the Chicago Board of Trade, which permitted certain telegraph companies to have its quotations for transmission to parties approved by it, could enjoin a company, which secured the quotations in some unknown manner, from distributing them to others. In this case it was held that the exchange did not lose its property right in the

quotations by communicating them to the telegraph companies.1 In a subsequent case the same court held that quotations on the New York Cotton Exchange were the property of the exchange, and that it could control their distribution in such a way as it saw fit. Similarly where a telegraph company, at considerable expense, collected news relating to current prices of securities, race track, baseball, and other events, it was held that the company's property in the news, which consisted largely in making it available in the shortest possible time after the happening of the events reported, was entitled to protection, and that this company could enjoin another from taking the news from its tape in the office of its patrons and delivering it with only a few moments loss of time to its own customers. And a company which collected advance information respecting the proposed construction of buildings, sewers, waterworks, and other public works, which it sold to subscribers under contract that it should be held in strict confidence, was granted an injunction restraining another from procuring the information from its subscribers and selling it in competition with it. The same principle appears to have been applied to entirely different facts in Fonotipia Co. (Ltd.) et al. . Bradley. There the Fonotipia Co. manufactured records for use on graphophones. The Continental Record Co. manufactured records from a matrix produced by them from the commercial records of the Fonotipia Co., and sold them in competition with it, advertising them at greatly reduced rates and as reproductions of the voices of artists under contract with the Fonotipia Co., asserting also that the records were identical with the originals. The Fonotipia Co. was granted an injunction restraining the rival company from selling copies of its records, the court holding it to be a wrongful appropriation of the property of the Fonotipia Co. Similarly, where a company manufactured illuminating gas called Prest-O-Lite for use on automobiles, and sold it in containers of peculiar construction, and had established depots in all the larger towns of the United States, where an empty container could be immediately exchanged for a filled one, it was held that the company could restrain a dealer from having said containers filled with a competing gas and disposing of them in competition with it without first obliterating there from the company's name, the word
