A. The Paris Convention is a treaty on an industrial property that was enacted on March 20, 1883, and entered into force on July 7, 1884.
Japan joined in 1899, and the Member States have the freedom to take legislative measures on industrial property rights (industrial property rights). For example, you can specify what the patent requirements and how the rights will be enforced, as long as they do not violate the provisions of the Paris Convention. The three principles are the principle of national treatment, the priority system, and the principle of patent independence in each country.
Priority, which is considered particularly relevant when acquiring intellectual property rights overseas, arises based on patent applications, applications for utility models, designs, and trademarks.
