The registration of a trade mark may not in all cases provide a complete defence to an action for infringement of trade mark or passing off. The basis of the concept and principle of passing off action is that a man is not to sell his own goods under the pretense that they are the goods of another man. There is no reason why a registered owner of a trade mark should be allowed to deceive purchasers into the belief that they are getting the goods of another while they would be buying the goods of the former which they never intended to do.
