The manifestations of trademark infringement are: (1) Using a trademark that is the same as or similar to its registered trademark on the same or similar goods without the permission of the registered trademark owner. Specifically, it includes four situations: 1. Using the same trademark as the registered trademark of others on the same commodity; 2. Use a trademark similar to the registered trademark of others on the same commodity; 3. Use the same trademark as the registered trademark of others on similar goods; 4. Use a trademark similar to the registered trademark of others on similar goods. Carrying out such acts without permission, whether intentional or negligent, constitutes an infringement of the exclusive right to use registered trademarks of others. (2) selling goods that are knowingly counterfeit registered trademarks. The seller subjectively knows or should know that he is selling goods with counterfeit registered trademarks, which constitutes such infringement. (3) Forging or manufacturing a registered trademark of another person without authorization or selling a forged or manufactured registered trademark. There are four main forms of this kind of infringement: 1. Forging the registered trademark of others; 2. Manufacturing its registered trademark logo without the authorization or authorization of the trademark owner; 3, beyond the authority granted by the trademark owner to arbitrarily manufacture its registered trademark logo; 4. Selling registered trademark marks that are forged or manufactured without authorization. (4) Acts that cause other damages to others' exclusive right to use a registered trademark. 1. Selling goods that you know or should know are infringing on the exclusive right to use registered trademarks of others. Take the principle of fault liability for such behavior. 2, on the same kind of goods, the same or similar words and graphics with other people's registered trademarks are used as the name of the goods or the decoration of the goods, which is enough to cause misunderstanding. 3. Deliberately providing convenient conditions such as warehousing, transportation, mailing, concealment, etc. for infringement of the exclusive right to use a registered trademark of others. This kind of infringement is based on intentional execution.
