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. It costs 2000 yuan to apply for renewal of registration. If an application for renewal of registration is filed within the grace period of six months after the expiration of the period, a late payment fee from 500 yuan shall 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. The period of validity of a trademark is 10 year, and the period of registration and use of the trademark is ten years from the date of expiration, counting from the date of approval of registration. If the expiration date is: 2012 1 110/1,the validity period after approval of renewal is 65438 in 2022. Trademark owners must pay attention to this. Trademark renewal is to ensure that all trademarks are in use, rather than wasting trademark resources and leaving trademarks blank. Trademark renewal is very important for trademarks. The reason why it was renewed 12 months before the expiration is to make the trademark ownership seamlessly connected. If it is renewed during the extension period, then the extension period actually has no right to use the trademark.
