What is the necessity of international protection of intellectual property rights?

Legal analysis: As long as a product is granted a patent right, it is equivalent to having an exclusive right in the market. Without the permission of the patentee, no one may produce, sell, promise to sell, use or import the patented product. Therefore, patents play a very important role in occupying and protecting the market. After GATT formulated the Agreement on the Protection of Trade-related Intellectual Property Rights, this role became more prominent.

Legal basis: Article 2 of the Paris Convention for the Protection of Industrial Property (1). With regard to the protection of industrial property rights, the nationals of any country in the Union shall enjoy all kinds of benefits that the nationals of that country now enjoy or may enjoy in all other countries in the Union, and nothing shall damage the rights specially stipulated in this Convention. Therefore, they should enjoy the same protection as nationals of the country and enjoy the same legal remedies when their rights are violated. (2) However, for nationals of countries of the Union, they should not be required to have a residence or business office in the country that requires protection in order to enjoy industrial rights. (3) Provisions on judicial and administrative procedures, jurisdiction, designation of service address or designation of agents in the laws of the countries of the Union that may be required by the Industrial Property Law shall be clearly retained.
