The conclusion of international contracts concerning licensing of intellectual property rights gradually increases and thus, it is necessary to study anti-trust laws, principles and policies in foreign countries and Korea, so as not to include unfair provisions or the contents conspiracy for trust in such contracts. An object of this study is to provide a licensor or licensee with a fair opportunity to grant or use various licenses under the circumstances which Intellectual Property Law match with the fair Trade Law.
The antitrust institution is in the complementary relation with the patent institution in the regards that through encouraging innovation and economic development, both are alimed at increasing consumer welfare in the ultimate dimension. in Korea, The Monopoly Regulation and Fair Trade Law Prescribes Article 59, This Article does not indicate that The monopoly Regulation and fair Trade Law shall not apply to any exercise of the intellectual property with no exception patents do not necessarily confer monopolistic power on their owners. Sometimes owners or acquirers of intellectual property can monopolize the relevant market, using the intellectual property as a leverage. In such situation, the Antitrust Law shall apply to any unfair or unjust exercise of the intellectual property rights. Therefore, it is most important to designate the boundary of the unfairness or unjustness with regards to the exercise of the rights under intellectual property laws, until recently, there has been no case where court or the Fair Trade Commission decided intellectual property owners conduct as illegal under Antitrust Law. In this paper, we observed the U.S. antitrust cases involving intellectual property issues. In so doing, we can learn some useful lessons in solving similar case that we can encounter sooner or later in the future.
