The validity period of a Chinese trademark certificate is 10 years. If you wish to check the expiration date of a specific Chinese trademark and have its trademark registration number on hand, you may use one of the following methods:
Log in to the official inquiry system of CNIPA (China National Intellectual Property Administration) Trademark Office via: https://sbj.cnipa.gov.cn/sbj/sbcx/
Pros: Results are authoritative and official.
Cons: Registration is required to access the system. You can only perform the inquiry after successful registration, making the process somewhat cumbersome for first-time users.
Use the trademark inquiry function on AiQicha, a professional enterprise information platform under Baidu. Visit: https://aiqicha.baidu.com/mark
Advantage: No registration is required currently. Simply enter the trademark number to get results.
