2. Prior right is a trademark law term, which refers to the right that others have obtained or enjoyed and protected by law before the applicant for a registered trademark filed an application for a registered trademark.

3. The prior right protected by the Trademark Law refers to the right that existed before the trademark application for registration and was legal and effective. At the same time, when different subjects apply for the same similar trademark on the same similar commodity on the same day, or apply for the registration of the trademark that was first used by others and has certain influence by improper means, the trademark law also protects the trademark that was first used.

Extended data:

The proof of prior rights is ultimately based on the strong evidence that the enterprise can provide. Therefore, in order to protect their rights, when applying for a trademark or patent, an enterprise should conduct copyright registration in advance, or use papers and witnesses to show its prior rights with more evidence.
