This constitutes the reverse trademark counterfeiting as 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 principles of good faith and fair competition, hinders the registrant's efforts to promote his trademark, expand trademark awareness and increase market share by selling goods, and damages the rights of trademark owners. Defining it as trademark infringement can better protect trademark owners.
