Anticompetitive business practices in which a dominant firm may engage in order to maintain or increase its position in the market. These business practices by the firm, not without controversy, may be considered as “abusive or improper exploitation” of monopolistic control of a market aimed at restricting competition. The term abuse of dominant position has been explicitly incorporated in competition legislation of various countries such as Canada, the EU and Germany. In the United States, the counterpart provisions would be those dealing with monopoly and attempts to monopolize or monopolization of a market.
