In the course of business operation, many people have a weak awareness of trademark law, incomplete understanding of trademark law, and can't correctly understand the legal effect of trademark registration certificate. Many people are deceived just because of a trademark registration certificate. In the course of business operation, when one party takes a registered trademark as some kind of proof, or shares intangible assets, the other party shall not consider the trademark right to be true and effective only by the other party's trademark registration certificate. The Trademark Office shall, in accordance with the Trademark Law, set up a trademark register to record registered trademarks and related registered matters. Enterprises should first consult the trademark registration book of the Trademark Office to understand its real legal status before making a decision. Similarly, in the process of law enforcement, the trademark administrative law enforcement department should first find out the true legal status of the trademark involved, and should not make a hasty decision just on a trademark registration certificate. Although the Trademark Registration Certificate itself cannot show the true legal status of the trademark, as a certificate issued by the state administrative organ, anyone who forges or alters the Trademark Registration Certificate will still be investigated for criminal responsibility in accordance with the provisions of the Criminal Law on the crime of forging or altering the certificates of state organs or other crimes. This point, enterprises should pay attention to in the process of operation. In particular, some small and medium-sized enterprises should pay attention not to blindly believe what is recorded in the trademark registration certificate, nor to treat it as a trivial matter. "Trademark Registration Certificate" is the legal certificate of registered trademark. When a trademark registrant prints its registered trademark logo, requests the administrative department for industry and commerce to handle the trademark infringement of others and brings a trademark infringement lawsuit to the people's court, it must issue a trademark registration certificate.
