1. Where can I apply for renewal of an expired trademark? You can entrust an agency or go to the Trademark Office yourself. 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 application documents to be submitted are: 1, trademark renewal registration application; 2, the applicant's identity certificate (copy); 3. Submit the power of attorney of the entrusted agent, and directly submit a copy of the agent's ID card in the acceptance hall; 4. A copy of the registration certificate; 5. If the application documents are in a foreign language, a Chinese translation signed and confirmed by the translation agency shall also be provided. 2. What are the precautions for trademark renewal? 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. 3. What is the importance of trademark renewal? Where it is necessary to continue to use a registered trademark after its expiration, it shall apply for renewal of registration within 12 months before its expiration; Failing to apply within this time limit, a grace period of 6 months may be granted. If no application is made at the expiration of the exhibition period, its registered trademark shall be cancelled. Each renewal of registration is valid for ten years. Many trademark owners think that the cost of trademark renewal is much more expensive than reapplication. As we all know, renewal is only a formal requirement to examine the subject qualification. After applying for renewal of the registration certificate, the exclusive right to use a trademark may be extended for 10 years without substantive examination. The reapplication of a trademark is the same as the new application. In addition to the formal requirements review, it is necessary to conduct a substantive review. The so-called substantive examination is to compare the applied trademark with the trademark in the trademark library. If they are identical or similar in advance, they will be rejected, thus losing the trademark right. Some applicants did not submit an application for extending the exclusive right time during the trademark renewal period. After that, I thought it was ok to reapply. In fact, I made a serious mistake, because I didn't know how many people wanted to use a good trademark. Maybe because of this step, I gave up my trademark right. It caused irreparable losses and then was repurchased at a high price. In addition, it takes longer to re-register a trademark than to renew it. To sum up, after successful trademark registration, there will be a valid period. Before the expiration of the validity period, the trademark holder shall bring the materials to the Trademark Office for renewal. After approval, the use period can be extended for ten years. To apply for trademark renewal, you need to prepare ID card, application for renewal, trademark registration certificate and other materials. If entrusted, a power of attorney should also be provided.
