The use of a trademark does not require registration. Even if you do not have a registered trademark, you can still use it. Generally speaking, it takes about one year from registration to authorization of a trademark. After passing the preliminary trademark review announcement, it takes about 2 months to obtain the trademark certificate. A special reminder is that before registering a trademark, you must first conduct a trademark search. Article 39 of the "Trademark Law of the People's Republic of China" The validity period of a registered trademark is ten years, calculated from the date of approval of registration. Article 40 of the "Trademark Law of the People's Republic of China" If a registered trademark expires and needs to be continued to be used, the trademark registrant shall go through the renewal procedures in accordance with the regulations within twelve months before the expiration; if the trademark fails to be renewed during this period, If the application is processed, a six-month extension period can be granted. Each renewal of registration is valid for ten years, starting from the day after the expiration of the previous term of validity of the trademark. If renewal procedures are not completed upon expiration, the registered trademark will be cancelled. The Trademark Office shall announce the renewal of registered trademarks.
