What is the meaning of regionality of intellectual property rights?

The regional characteristics of intellectual property rights mean that a right protected by a country's intellectual property laws will only take legal effect within the country if an international convention on intellectual property rights or a bilateral reciprocal agreement on intellectual property rights is signed. For example, if you apply for a patent in the United States, it will only have legal effect in the United States. Trademark right, registered in Japan, has legal effect only in Japan. If you want to be protected in China, you must apply or register with the World Intellectual Property Organization, or apply or register directly in China. Copyright (copyright) is generally obtained automatically, and its regionality is not as strong as that of patent right and trademark right. For example, as long as the member countries join the Berne Convention, the works of copyright owners among the member countries should be protected according to their respective copyright laws, but if they do not join the relevant international conventions or sign bilateral copyright protection agreements, they will not be protected, so the copyright is also regional.
