This constitutes a reverse trademark counterfeiting act stipulated in the Trademark Law, which is illegal. Reverse counterfeiting refers to the behavior that the actor changes his registered trademark without the consent of the trademark registrant and puts the goods with the changed trademark back on the market. Reverse counterfeiting violates the principle of good faith and fair competition, which hinders the registrant's efforts to publicize his trademark, expand his trademark popularity and increase market share by selling goods, thus damaging the rights of trademark owners. It can better protect trademark owners by defining it as trademark infringement.
