This article is intended to examine the public order and social morals provisions stipulated in Korea's Intellectual Property Act and briefly presents the author's opinion. Like other property rights laws, the law governing intellectual property rights as property rights also stipulates public order and social morals provisions. International norms and the intellectual property laws of Japan and Germany also have provisions for public order and social morals. There is no public order and social morals clause in the copyright act, which is a representative system that protects creative works. It is my thought that this is because a copyrighted work is a creation that results from mental labor and is closely related to freedom of expression, freedom of art, freedom of study, and freedom of thought, so it has a somewhat different nature from patent rights and trademark rights. In this article, the author examines the public order and social morals provisions stipulated in international norms and the patent laws of Germany and Japan, as well as the public order and social morals provisions stipulated in Korea's patent law, trademark law, copyright law, and design protection law, and that the intellectual property rights system is also consistent with the overall legal order. I would like to point out that public order and social morals must be maintained in the intellectual property rights system. Restricting the creation or exercise of property rights with an uncertain and fluid concept of public order and social morals can cause legal instability. In particular, the concept of “public health” stipulated in the Patent Act appears to need to be revised. Personally, the author believes that the establishment of patent rights at the Korean Intellectual Property Office is a quasi-legal administrative act that occurs in accordance with scientific administration or technological administration and is conducted by patent office examiners, but from the perspective of rule of law administration, there are some concerns. The public order and morals clause is an expression of the state's intention not to tolerate intellectual property rights if they are created in violation of the social order that our country must maintain, and that it will not accept content that violates public order and social morals even in the area of intellectual property rights. It can be said to be the legislator's decision. Within the intellectual property law system, the public order and social morals clause can be said to be an institutional mechanism that prevents intellectual property rights from being abused or flowing in socially harmful directions. In addition, the public order and social morals clause has a positive function in that it can be said to provide a certain degree of control from the perspective of law against science omnipotence, technology primacy, etc. However, although the goals of the Patent Act, Trademark Act, and Design Protection Act are somewhat different, the public order and social morals provisions are aimed at a common legal order, so it is believed that they need to be regulated as unified content.
