Japanese Patent FAQs
Methods for Treatment of the Human Body
Q.Is there any general prohibition as to the patenting of methods for treatment of the human body by surgery or therapy in Japan?
An invention concerning a method for diagnosis, operation, treatment, and/or disease prevention is not patentable subject matter in Japan and will thus be rejected by the Japanese Patent Office. Claims that have not been searched by the International Searching Authority are not preferably treated in Japan.
