What are the four principles of Paris Convention patents?

The priority principle of Paris Convention patent means that citizens of Paris Convention member countries should have priority when they file the same patent application in their own countries. Among them, the priority of invention patent and utility model patent is 12 months, and the priority of appearance patent is 6 months. 2. The principle of patent independence in the Paris Convention means that the patents obtained by the same application in different countries are not related. In other words, the patent applicant has obtained the patent right in one of the member countries, but the other country may not be able to obtain it smoothly. Similarly, being rejected in one country does not mean that the application will fail in other countries! 3. Principle of compulsory licensing of patents in Paris Convention: According to Paris Convention, member countries can adopt legislative measures to stipulate that compulsory licensing can be approved under certain conditions, so as to prevent the patentee from abusing the patent right. If the patentee fails to implement or not fully implement the patent within four years from the date of application or three years from the date of patent approval (whichever is longer), the relevant member States have the right to take legislative measures to approve the compulsory license and allow a third party to implement the patent. 4. Temporary protection of exhibition products of Paris Convention patents. Each member state of Paris Convention shall provide temporary legal protection for products and patents exhibited in international exhibitions held in its territory according to its own legal provisions.
