The United States Trade-Mark Act of July 5, 1946, is a statute designed to be of far-reaching effect. The appraisal of the statute must be made in the light of that fact rather than in the light of the confusion and disputation which have arisen as to the proper interpretation of many of its provisions.

One might have supposed that an act which had been subjected to intensive study and extensive revision over so many years before its final enactment would emerge in complete clarity. Such has not proved to be the case; and it should not have been expected. The very variety of trade-mark problems makes it obviously impossible to put into a single document a definite answer to every one of them.
