INTERNATIONAL NEWS SERVICE
Supreme Court of the United States
248 U.S. 215
Argued May 2 and 3, 1918
Decided Dec. 23, 1918
Mr. Justice BRANDEIS, dissenting.
 No question of statutory copyright is involved. The sole question for our consideration is this: Was the International News Service properly enjoined from using, or causing to be used gainfully, news of which it acquired knowledge by lawful means (namely, by reading publicly posted bulletins or papers purchased by it in the open market) merely because the news had been originally gathered by the Associated Press and continued to be of value to some of its members, or because it did not reveal the source from which it was acquired? . . .
 News is a report of recent occurrences. The business of the news agency is to gather systematically knowledge of such occurrences of interest and to distribute reports thereof. The Associated Press contended that knowledge so acquired is property, because it costs money and labor to produce and because it has value for which those who have it not are ready to pay; that it remains property and is entitled to protection as long as it has commercial value as news; and that to protect it effectively, the defendant must be enjoined from making, or causing to be made, any gainful use of it while it retains such value. An essential element of individual property is the legal right to exclude others from enjoying it. If the property is private, the right of exclusion may be absolute; if the property is affected with a public interest, the right of exclusion is qualified. But the fact that a product of the mind has cost its producer money and labor, and has a value for which others are willing to pay, is not sufficient to ensure to it this legal attribute of property. The general rule of law is, that the noblest of human productions—knowledge, truths ascertained, conceptions, and ideas—become, after voluntary communication to others, free as the air to common use. Upon these incorporeal productions the attribute of property is continued after such communication only in certain classes of cases where public policy has seemed to demand it. These exceptions are confined to productions which, in some degree, involve creation, invention, or discovery. But by no means all such are endowed with this attribute of property. The creations which are recognized as property by the common law are literary, dramatic, musical, and other artistic creations; and these have also protection under the copyright statutes. The inventions and discoveries upon which this attribute of property is conferred only by statute, are the few comprised within the patent law. There are also many other cases in which courts interfere to prevent curtailment of plaintiff’s enjoyment of incorporeal productions; and in which the right to relief is often called a property right, but is such only in a special sense. In those cases, the plaintiff has no absolute right to the protection of his production; he has merely the qualified right to be protected as against the defendant’s acts, because of the special relation in which the latter stands or the wrongful method or means employed in acquiring the knowledge or the manner in which it is used. Protection of this character is afforded where the suit is based upon breach of contract or of trust or upon unfair competition.
 The knowledge for which protection is sought in the case at bar is not of a kind upon which the law has heretofore conferred the attributes of property; nor is the manner of its acquisition or use nor the purpose to which it is applied, such as has heretofore been recognized as entitling a plaintiff to relief.
 Plaintiff further contended that defendant’s practice constitutes unfair competition, because there is ‘appropriation without cost to itself of values created by’ the plaintiff; and it is upon this ground that the decision of this court appears to be based. To appropriate and use for profit, knowledge and ideas produced by other men, without making compensation or even acknowledgment, may be inconsistent with a finer sense of propriety; but, with the exceptions indicated above, the law has heretofore sanctioned the practice. Thus it was held that one may ordinarily make and sell anything in any form, may copy with exactness that which another has produced, or may otherwise use his ideas without his consent and without the payment of compensation, and yet not inflict a legal injury; and that ordinarily one is at perfect liberty to find out, if he can by lawful means, trade secrets of another, however valuable, and then use the knowledge so acquired gainfully, although it cost the original owner much in effort and in money to collect or produce.
 Such taking and gainful use of a product of another which, for reasons of public policy, the law has refused to endow with the attributes of property, does not become unlawful because the product happens to have been taken from a rival and is used in competition with him. The unfairness in competition which hitherto has been recognized by the law as a basis for relief, lay in the manner or means of conducting the business; and the manner or means held legally unfair, involves either fraud or force or the doing of acts otherwise prohibited by law. In the ‘passing off’ cases (the typical and most common case of unfair competition), the wrong consists in fraudulently representing by word or act that defendant’s goods are those of plaintiff. In the other cases, the diversion of trade was effected through physical or moral coercion, or by inducing breaches of contract or of trust or by enticing away employees. In some others, called cases of simulated competition, relief was granted because defendant’s purpose was unlawful; namely, not competition but deliberate and wanton destruction of plaintiff’s business.
 That competition is not unfair in a legal sense, merely because the profits gained are unearned, even if made at the expense of a rival, is shown by many cases besides those referred to above. He who follows the pioneer into a new market, or who engages in the manufacture of an article newly introduced by another, seeks profits due largely to the labor and expense of the first adventurer; but the law sanctions, indeed encourages, the pursuit. He who makes a city known through his product, must submit to sharing the resultant trade with others who, perhaps for that reason, locate there later. He who has made his name a guaranty of quality, protests in vain when another with the same name engages, perhaps for that reason, in the same lines of business; provided, precaution is taken to prevent the public from being deceived into the belief that what he is selling, was made by his competitor. One bearing a name made famous by another is permitted to enjoy the unearned benefit which necessarily flows from such use, even though the use proves harmful to him who gave the name value.
 The means by which the International News Service obtains news gathered by the Associated Press is also clearly unobjectionable. It is taken from papers bought in the open market or from bulletins publicly posted. No breach of contract such as the court considered to exist in Hitchman Coal & Coke Co. v. Mitchell, 245 U. S. 229, 254, or of trust such as was present in Morison v. Moat, 9 Hare, 241; and neither fraud nor force is involved. The manner of use is likewise unobjectionable. No reference is made by word or by act to the Associated Press, either in transmitting the news to subscribers or by them in publishing it in their papers. Neither the International News Service nor its subscribers is gaining or seeking to gain in its business a benefit from the reputation of the Associated Press. They are merely using its product without making compensation. That they have a legal right to do, because the product is not property, and they do not stand in any relation to the Associated Press, either of contract or of trust, which otherwise precludes such use. The argument is not advanced by characterizing such taking and use a misappropriation.
 It is also suggested that the fact that defendant does not refer to the Associated Press as the source of the news may furnish a basis for the relief. But the defendant and its subscribers, unlike members of the Associated Press, were under no contractual obligation to disclose the source of the news; and there is no rule of law requiring acknowledgment to be made where uncopyrighted matter is reproduced. The International News Service is said to mislead its subscribers into believing that the news transmitted was originally gathered by it and that they in turn mislead their readers. There is, in fact, no representation by either of any kind. Sources of information are sometimes given because required by contract; sometimes because naming the source gives authority to an otherwise incredible statement; and sometimes the source is named because the agency does not wish to take the responsibility itself of giving currency to the news. But no representation can properly be implied from omission to mention the source of information except that the International News Service is transmitting news which it believes to be credible.
 Nor is the use made by the International News Service of the information taken from papers or bulletins of Associated Press members legally objectionable by reason of the purpose for which it was employed. The acts here complained of were not done for the purpose of injuring the business of the Associated Press. Their purpose was not even to divert its trade, or to put it at a disadvantage by lessening defendant’s necessary expenses. The purpose was merely to supply subscribers of the International News Service promptly with all available news.
 The great development of agencies now furnishing country-wide distribution of news, the vastness of our territory, and improvements in the means of transmitting intelligence, have made it possible for a news agency or newspapers to obtain, without paying compensation, the fruit of another’s efforts and to use news so obtained gainfully in competition with the original collector. The injustice of such action is obvious. But to give relief against it would involve more than the application of existing rules of law to new facts. It would require the making of a new rule in analogy to existing ones. The unwritten law possesses capacity for growth; and has often satisfied new demands for justice by invoking analogies or by expanding a rule or principle. This process has been in the main wisely applied and should not be discontinued. Where the problem is relatively simple, as it is apt to be when private interests only are involved, it generally proves adequate. But with the increasing complexity of society, the public interest tends to become omnipresent; and the problems presented by new demands for justice cease to be simple. Then the creation or recognition by courts of a new private right may work serious injury to the general public, unless the boundaries of the right are definitely established and wisely guarded. In order to reconcile the new private right with the public interest, it may be necessary to prescribe limitations and rules for its enjoyment; and also to provide administrative machinery for enforcing the rules. It is largely for this reason that, in the effort to meet the many new demands for justice incident to a rapidly changing civilization, resort to legislation has latterly been had with increasing frequency.
 The rule for which the plaintiff contends would effect an important extension of property rights and a corresponding curtailment of the free use of knowledge and of ideas; and the facts of this case admonish us of the danger involved in recognizing such a property right in news, without imposing upon news-gatherers corresponding obligations. A large majority of the newspapers and perhaps half the newspaper readers of the United States are dependent for their news of general interest upon agencies other than the Associated Press. The channel through which about 400 of these papers received, as the plaintiff alleges, ‘a large amount of news relating to the European war of the greatest importance and of intense interest to the newspaper reading public’ was suddenly closed. The closing to the International News Service of these channels for foreign news (if they were closed) was due not to unwillingness on its part to pay the cost of collecting the news, but to the prohibitions imposed by foreign governments upon its securing news from their respective countries and from using cable or telegraph lines running therefrom. For aught that appears, this prohibition may have been wholly undeserved; and at all events the 400 papers and their readers may be assumed to have been innocent. For aught that appears, the International News Service may have sought then to secure temporarily by arrangement with the Associated Press the latter’s foreign news service. For aught that appears, all of the 400 subscribers of the International News Service would gladly have then become members of the Associated Press, if they could have secured election thereto. It is possible, also, that a large part of the readers of these papers were so situated that they could not secure prompt access to papers served by the Associated Press. The prohibition of the foreign governments might as well have been extended to the channels through which news was supplied to the more than a thousand other daily papers in the United States not served by the Associated Press; and a large part of their readers may also be so located that they cannot procure prompt access to papers served by the Associated Press.
 A Legislature, urged to enact a law by which one news agency or newspaper may prevent appropriation of the fruits of its labors by another, would consider such facts and possibilities and others which appropriate inquiry might disclose. Legislators might conclude that it was impossible to put an end to the obvious injustice involved in such appropriation of news, without opening the door to other evils, greater than that sought to be remedied.
 Or legislators dealing with the subject might conclude, that the right to news values should be protected to the extent of permitting recovery of damages for any unauthorized use, but that protection by injunction should be denied, just as courts of equity ordinarily refuse (perhaps in the interest of free speech) to restrain actionable libels, and for other reasons decline to protect by injunction mere political rights; and as Congress has prohibited courts from enjoining the illegal assessment or collection of federal taxes. If a Legislature concluded to recognize property in published news to the extent of permitting recovery at law, it might, with a view to making the remedy more certain and adequate, provide a fixed measure of damages, as in the case of copyright infringement.
 Or again, a Legislature might conclude that it was unwise to recognize even so limited a property right in published news as that above indicated; but that a news agency should, on some conditions, be given full protection of its business; and to that end a remedy by injunction as well as one for damages should be granted, where news collected by it is gainfully used without permission. If a Legislature concluded that under certain circumstances news-gathering is a business affected with a public interest; it might declare that, in such cases, news should be protected against appropriation, only if the gatherer assumed the obligation of supplying it at reasonable rates and without discrimination, to all papers which applied therefor. If legislators reached that conclusion, they would probably go further, and prescribe the conditions under which and the extent to which the protection should be afforded; and they might also provide the administrative machinery necessary for insuring to the public, the press, and the news agencies, full enjoyment of the rights so conferred.
 Courts are ill-equipped to make the investigations which should precede a determination of the limitations which should be set upon any property right in news or of the circumstances under which news gathered by a private agency should be deemed affected with a public interest. Courts would be powerless to prescribe the detailed regulations essential to full enjoyment of the rights conferred or to introduce the machinery required for enforcement of such regulations. Considerations such as these should lead us to decline to establish a new rule of law in the effort to redress a newly disclosed wrong, although the propriety of some remedy appears to be clear.
