(1)Disparagement. Some industry codes which prohibit practices such as "disparagement," "disparagement of competitors," "improper disparagement," "unfairly attaching," "discrediting," may operate as a restriction on comparative advertising. The Commission has previously held that disparaging advertising is permissible so long as it is truthful and not deceptive. In Carter Products, Inc., 60 F.T.C. 782, modified, 323 F.2d 523 (5th Cir. 1963), the Commission narrowed an order recommended by the hearing examiner which would have prohibited respondents from disparaging competing products through the use of false or misleading pictures, depictions, or demonstrations, "or otherwise" disparaging such products. In explaining why it eliminated "or otherwise" from the final order, the Commission observed that the phrase would have prevented:respondents from making truthful and non-deceptive statements that a product has certain desirable properties or qualities which a competing product or products do not possess. Such a comparison may have the effect of disparaging the competing product, but we know of no rule of law which prevents a seller from honestly informing the public of the advantages of its products as opposed to those of competing products. 60 F.T.C. at 796.
Industry codes which restrain comparative advertising in this manner are subject to challenge by the Federal Trade Commission.
