delivered the opinion of the court.
This is a bill to prevent the defendant Walter E. Mas-land from using or disclosing secret prоcesses the knowledge of which was acquired by the defendant while in the plаintiffs’ employ. The defendant admits that he intends to manufacture artificial leаther, to which some of the plaintiffs’ alleged secret processes relate, but denies that he intends to use any inventions, trade secrets, or secret processes of the plaintiffs that he may have learned in any confidеntial relation, prefacing his denial, however, with the averment that many of the things claimed by the plaintiffs are well known to the trade. A preliminary injunction was refused at first. 216 Fed. Rep. 271. But before the final hearing the defendant proposеd to employ *102 one or more experts and to make such disclosures to them as the preparation of the defence might require. Thereupon the District Court issued a preliminary injunction against disclosing any of the plaintiffs’ allеged processes to experts or witnesses during the taking of proofs, but excepting counsel, with leave to move to dissolve the injunction if occаsion to consult experts arose. Later a motion to dissolve was deniеd and the hearing was continued for a decision by the Appellate Court. 222 Fеd. Rep. 340. The Circuit Court of Appeals reversed the decree. 224 Fed. Rep. 689. Before any further order was entered the writ of certiorari was granted by this сourt.
The case has been considered as presenting a conflict between a right of property and a right to make a full defence, and it is said that if the disclosure is forbidden to one who denies that there is a trade secret, the merits of his defence are adjudged against him before he has a chаnce to be heard or to prove his case. We approach the question somewhat differently. The word property as applied to trаde-marks and trade secrets is an unanalyzed expression of certain secondary consequences of the primary fact that the law makes some rudimentary requirements of good faith. Whether the plaintiffs have any valuable secret or not the defendant knows the facts, whatever they are, through а special confidence that he accepted. The proрerty may be denied but the confidence cannot be. Therefore the stаrting point for the present matter is not property or due process of law, but that the defendant stood in confidential relations with the plaintiffs, or one of them. These have given place to hostility, and the first thing to be made sure of is that the defendant shall not fraudulently abuse tne trust reposed in him. It is the usual incident оf confidential relations. If there is any disadvantage in the fact that he knew the plaintiffs’ secrets he must take the burden with the good.
*103 The injunction asked by the plaintiffs forbade only the disclosure of processes claimed by them, including the disсlosure to experts or witnesses "produced during the taking of proofs — but excepting the defendant’s counsel. Some broader and ambiguous words that crеpt into the decree, seemingly by mistake, may be taken as stricken out and left on one side. This injunction would not prevent the defendant from directing questions thаt should bring out whatever public facts were nearest to the alleged secrets. Indeed it is hard to see why it does not leave the plaintiffs’ rights somewhat illusory. No very clear ground as yet has been shown for going further. But the judge who tries the cаse will know the secrets, and if in his opinion and discretion it should be advisable and nеcessary to take in others, nothing will prevent his doing so. It will be understood that if, in the оpinion of the trial judge, it is or should become necessary to reveal thе secrets to. others it will rest in the judge’s discretion to determine whether, to whom, and under what precautions, the revelation should be made.
Decree reversed and case remanded for further proceedings in conformity with this opinion.
