Just that trademarks have different functions does not necessarily constitute infringement. It depends on whether the two trademarks are similar, which may easily lead to confusion among the relevant public. Infringement of the exclusive right to use a registered trademark mainly includes the following acts: 1. Using the same or similar trademark on the same or similar goods without the permission of the registered trademark owner. 2, without the consent of the trademark registrant, change its registered trademark and put the goods with the changed trademark on the market again. This kind of behavior is also called "reverse impersonation" in theory. 3. Selling goods that infringe the exclusive right to use a registered trademark. 4. Forgery or unauthorized manufacture of another person's registered trademark logo or sale of forged or unauthorized registered trademark logo. It should be noted that this kind of infringement is trademark infringement, including "manufacturing" and "selling". 5. Acts that cause other damage to the exclusive right to use a registered trademark of others.
