Legal analysis: Normally it is 3 years, and a trademark that is not used for three years will be revoked. Generally, the trademark office will not deliberately inquire. However, if a registered trademark has not been used for three consecutive years, anyone can apply to the Trademark Office of the State Administration for Industry and Commerce to cancel the registered trademark. After the State Trademark Office accepts the cancellation application, it will send a letter to notify the registrant to provide evidence of use within the legal period. If it is not provided in time, the trademark will be revoked. After the company is deregistered, the trademark can be transferred. Trademark transfer must be carried out within the validity period of the trademark. Once the trademark expires, the trademark will be invalid. Trademark transfer is very important in corporate trademark management. If you are running a company and preparing to cancel it, it is best to submit a trademark transfer application before the company cancels the company. However, the trademark transfer cycle is long. Some companies have submitted a trademark transfer application and then canceled the company. However, the company has canceled the trademark and the trademark transfer failed. The trademark is still under the name of the original company.
