COMPARATIVE EXAMINATION AND INVESTIGATION OF DILUTION DOCTRINE IN INTELLECTUAL PROPERTY LAW

The main purpose of trademark legal system is protection of trademark against any unauthorized use، so today many of existing legal systems have provide different enforcements for breach of trademark. Well known trademarks have always been considered as a valuable property by legislatures and protected as a particular category of trademarks. On contrary to infringement، Dilution doctrine، which is also named as breach of second type، is to protect well known trademarks against any unauthorized use and its exact purpose is to establish particular protection from owners of trademarks so as to provide required status for protecting both consumers and owners of trademarks. Although this doctrine has not ever had a show in our precedent، our legislature painstakingly provided it at paragraph V of article 32 of inventions، industrial designs and trademarks act.
