Trademark renewal can be applied online. However, according to the provisions of China's Trademark Law, if a trademark is renewed before its expiration, an application can be filed through the Internet, but the relevant application materials need to be sent to the Trademark Office. Where a registered trademark needs to be used continuously after the expiration of its term of validity, the trademark registrant shall go through the renewal procedures in accordance with the provisions within 12 months before the expiration; If it has not been handled during this period, it can be extended for six months. The validity period of each renewal registration is ten years, counting from the day after the last expiration of the trademark. If the renewal formalities are not completed at the expiration of the period, the registered trademark shall be cancelled. The Trademark Office shall announce the renewed registered trademark. There are two ways to apply for the renewal of a registered trademark: (1) entrusting a trademark agency to file with the Trademark Office. (2) The applicant goes directly to the trademark registration hall of the Trademark Office. (3) The applicant applies online through online registration of Chinese trademarks. There is only one file format for renewal, that is, the application for trademark renewal registration. (1) The application documents to be submitted when preparing the application documents are: (1) trademark renewal registration application; (2) the applicant's identity certificate (copy); (3) the power of attorney of the entrusted agent; (4) A copy of the agent's ID card submitted directly in the acceptance hall; (5) If the application document is in a foreign language, the signature of the translation agency shall also be provided. 2. Each trademark shall submit 1 application for registration renewal. 3, directly to the trademark registration hall, should submit a copy of the agent's ID card; Where a trademark agency is entrusted, a power of attorney for trademark agency shall be submitted. 4. The trademark applied for renewal is * * *, and the application shall be filed in the name of the representative. (2) Submit the application form 1. If the applicant goes directly to the trademark registration hall, after the application form is ready, submit it at the acceptance window of the trademark registration hall, and the staff at the window will confirm whether the application form is qualified. 2. Where a trademark agency is entrusted, the trademark agency shall serve the application to the Trademark Office. (III) Payment of renewal fee The application for renewal registration needs to pay a fee of 1 000 yuan. If the application for renewal of registration is submitted within the grace period of six months after the expiration of the time limit, a late fee from 250 yuan will be paid. Where a trademark agency is entrusted, the applicant shall pay the renewal fee and agency fee to the trademark agency, and the renewal fee charged by the trademark office shall be deducted from the advance payment of the trademark agency. Note 1. After the renewal application is approved, the Trademark Office will mail the renewal certificate to the applicant according to the address filled in the application. 2. If the application for renewal does not meet the requirements, the Trademark Office will notify the applicant in writing by post to make corrections within a time limit according to the address filled in the application. 3. If the renewal application cannot be approved for other reasons, the Trademark Office will notify the applicant in writing by post according to the address filled in the application. If the applicant entrusts a trademark agency to apply for renewal, the Trademark Office will not have any direct contact with the applicant, and all documents will be sent to the trademark agency. 5. The category of application shall be filled in according to the international classification approved by the Trademark Registration Certificate. To sum up, the trademark renewal is mainly because the trademark originally applied for protection is about to expire and will be cancelled. Therefore, what the parties need to do is to prepare all the information and make a request to the Trademark Office to retain the trademark. Although online channels have been opened to provide applications, they still can't work online.
