The availability of a wide range of branded products makes the selection of the right type of goods a difficult process. This is particularly true in the case of goods whose characteristics consumers do not have complete information about, which they can only learn about after purchasing (experiencing goods). A trade mark quality guarantee facilitates consumers' choice by sending quality signals. It also enables a trader of branded goods to differentiate the quality of his goods from those of his competitors. Accordingly, trade mark protection is said to enhance economic efficiency, and thus the production of quality goods, and reduce consumer search costs.
