Advertising and the Public Interest: Legal Protection of Trade Symbols
Brown, Ralph S., Jr., The Yale Law Journal
"The protection of trade-marks is the law's recognition of the psychological function of symbols. If it is true that we live by symbols, it is no less true that we purchase goods by them. A trademark is a merchandising short-cut which induces a purchaser to select what he wants, or what he had been led to believe he wants. The owner of a mark exploits this human propensity by making every effort to impregnate the atmosphere of the market with the drawing power of a congenial symbol. Whatever the means employed, the end is the same--to convey through the mark, in the minds of potential customers, the desirability of the commodity upon which it appears. Once this is attained, the trademark owner has something of value. If another poaches upon the commercial magnetism of the symbol he has created, the owner can obtain legal redress." Frankfurter, J., in Mishawaka Rubber & Woolen Mfg. Co. v. S.S. Kresge Co.(1)
The law of trade symbols is of modern development, largely judge-made and only partly codified.(2) Its impetus comes from the demands of modern advertising, a black art(3) whose practitioners are part of  the larger
army which employs threats, cajolery, emotions, personality, persistence and facts in what is termed aggressive selling. Much aggressive selling involves direct personal relationships; advertising depends on the remote manipulation of symbols, most importantly of symbols directed at a mass audience through mass media, or imprinted on mass-produced goods. The essence of these symbols is distilled in the devices variously called trade-marks, trade names, brand names, or trade symbols. To the courts come frequent claims for protection, made by those who say they have fashioned a valuable symbol, and that no one else should use it. Very recently, for example, the vendors of Sun-Kist oranges lost a court battle to prevent an Illinois baker from selling Sun-Kist bread.(4) The highest court, in its most recent encounter with a like case, upheld the power of a manufacturer of robber footwear to prevent the use of a red circle mark by a seller of rubber heels, which the plaintiff did not manufacture.(5)
In these cases, a choice of premises and techniques is still open. One set of premises, which seems to subsume Justice Frankfurter's felicitous dictum, recognizes a primary public interest in protecting the seller who asks the court to enjoin "another [who] poaches upon the commercial magnetism of a symbol he has created." This expansive conception merits critical attention. Are all forms of poaching forbidden? Should they be, consistent with another premise? This one asserts, in the words of Judge Frank, "the basic common law policy of encouraging competition, and the fact that the protection of monopolies in names is but a secondary and limiting policy."(6) The legal ties which bind together some apparently inconsistent decisions may be found, but not simply in an indiscriminate prohibition of poaching, nor yet in a presumption in favor of competition, no matter how compelling. Rather, courts move from these and other premises to refinements of doctrine.
It is proposed here to seek, in the milieu in which trade symbols are created and used, for data underlying both premises and dogma. This will require an independent evaluation of the institution of advertising. What do we get for the three billions of current annual outlay?(7) Do  we want it? Unfortunately, there is little consensus as to what values advertising serves. Its votaries have poured their most skillful symbols back in the soil from which they sprang.(8) Its detractors, maddened by the success of this propaganda, would purge Radio City with fire and sword.(9) One thing the examination will reveal is that what appear to be private disputes among hucksters almost invariably touch the public welfare. We shall therefore be concerned to ask, when courts protect trade symbols, whether their decisions further public as well as private goals. …
