The basic principles of intellectual property law are as follows:

1. The principle of national treatment, that is, in protecting industrial property rights, each member state must give the nationals of other member States equal access to the protection and treatment that their nationals can get.

2. the principle of priority, that is, the state party has the obligation to give priority treatment to the nationals of other States parties. The so-called priority means that nationals of each contracting state may request the first filing date as the next filing date if they file the same application for the same content with other member States within a certain period of time on the basis of filing a formal application for an industrial property right with one member state for the first time.

3. Principle of independence, that is, the exclusive right to use a patent or a trademark granted for the same invention or trademark among member countries is independent of each other, examined and approved according to their own laws, and does not affect each other.

4. The principle of compulsory license, that is, the patentee of a member country must exploit its patented invention within a certain period of time, otherwise, the patent authority of the member country has the right to issue a compulsory license to exploit the patent upon request, or revoke the patent right according to law.

the so-called basic principles of intellectual property law refer to the guiding ideology and basic principles that embody and run through the whole intellectual property legislation, law enforcement, judicature and law popularization.
