의약용도발명의 독자적 위상 정립에 관한 소고

초록

The subject of protection under Republic of KOREA patent law is an invention. According to Article 2, Paragraph 1 of the Patent Act, "An invention is the creation of a technical idea utilizing the laws of nature, which is highly advanced." However, due to rapid changes in the era and high-speed technological innovation, new technologies that do not fit the traditional definition of an invention, such as computer programs, business methods, and pharmaceutical use inventions, are continuously emerging. Furthermore, the patent examination guidelines in South Korea have been granting patent rights to discoveries, which fall outside the scope of inventions, and are treated differently under patent law. As a result, in practice, discoveries are already recognized as inventions, and the current legal definition of an invention is limited in its ability to comprehensively protect technologies that are rapidly evolving in today's world. This paper discusses the limitations of the current legal definition of an invention, the classification system, the description method in patent specifications, and the need for restricting the effects of patent rights, particularly in relation to pharmaceutical use inventions. Pharmaceutical use inventions are difficult to fit into the existing definition of an invention, as defined by current patent law. Moreover, the fact that pharmaceutical use inventions are primarily protected as inventions related to products, rather than as inventions directly related to medical treatments, reflects a policy decision made due to the need for recognizing the importance of the medical industry’s development and the protection of medical technologies, even though such inventions do not qualify as inventions for human treatment methods under patent law. The development of new and innovative therapeutic uses for existing pharmaceutical products is accelerating. However, under the current examination guidelines, pharmaceutical use inventions can only be described in terms of product claims, leading to discrepancies between the actual nature of the invention and the way it is expressed in the claims. This results in confusion regarding the relationship between pharmaceutical substance inventions and pharmaceutical use inventions, which could lead to issues such as errors in the scope of patent rights. Therefore, there is a need to establish a separate classification system that takes into account the specific characteristics of pharmaceutical use inventions, which are difficult to clearly categorize under the current patent law. Additionally, in order to ensure clarity in the interpretation of patent rights and relationships, and to protect both medical professionals and patients from ethical concerns, revisions to patent law and practical guidelines should be considered. In conclusion, it is necessary to establish a clear classification system for pharmaceutical use inventions, which primarily involve the discovery of new uses for pharmaceutical substances, as they are difficult to clearly categorize within the current framework of patent law. This would help establish the independent status of pharmaceutical use inventions and address the need for proper protection under patent law.
