Trademark renewal has the advantages of short time, low overall cost and low risk. Therefore, everyone must understand the validity period and expiration date of their trademark, and renew it within one year before expiration. Of course, don’t be afraid if you accidentally failed to renew the trademark. There is still a 6-month extension period after the trademark expires, and you can also renew it. Trademark renewal is to extend the use period of a registered trademark. Its application procedure is relatively simple. It only examines the formal conditions of the subject qualifications and does not need to go through the substantive review stage, so it takes about 6 months to get the renewal certification certificate. If you re-register a trademark, the same trademark and the same category will have an additional one-year protection period. In total, it will take you at least 2 years to get your previous trademark back. This is 4 times as long as trademark renewal! Therefore, if you urgently need to use your trademark, trademark renewal is more suitable for you.
