The validity period of a registered trademark is ten years, which is the same as the regulations in most countries in the world, and is also consistent with the Madrid system for international trademark registration.

Since the exclusive right to register a trademark in my country arises from trademark registration, the validity period of a registered trademark referred to in this article is also the validity period of the exclusive registered right. During this period of validity, the owner of the exclusive right to register a trademark can fully exercise the rights of possession, use, disposal, income and derived prohibition rights protected by law, including prohibiting others from applying for registration of the same similar trademark or service. If the right holder's trademark is identical or similar, others are prohibited from using the registered trademark without permission.
