Power gives Brand: The Relationship between Competition law and Segment Particular Control

This work has the purposes of analyzing the different treatments trademarks are subject in the fields of merger control and antitrust infringement proceedings. The analysis of the social function of trademark showed that it is a property that becomes effective in and by means of competition. In this sense, there is no doubt that it is subject to the principles of Antitrust Law. However, the way these principles limits trademark rights in the context of merger control, on one side, and, antitrust infringement proceedings, on the other, varies. In the field of merger control, the antitrust authority is guided by a variant of the precautionary principle, which empowers it to make decisions and impose restrictions to trademark rights even in a context of uncertainty.
