Legal analysis: the trademark is infringed, and the goods infringed by others should be fixed by taking photos, videos, buying physical objects, etc. When necessary, the evidence should be notarized and preserved first. If the other party's infringement is not serious and is willing to settle it through consultation, both parties may settle the infringement facts and compensation through consultation. If the infringement is serious, you can complain to the administrative department for industry and commerce about the infringement. It should be noted that the law stipulates that if a trademark registrant complains to the administrative department for industry and commerce to protect his exclusive right to use a trademark, he shall submit a written complaint application, and at the same time attach his valid certification materials, including the complaint, trademark registration certificate and pictures of the actual use of the trademark by both parties. If they are unwilling to negotiate or fail to do so, they may bring a lawsuit directly to the people's court according to law. By bringing a civil lawsuit, you can ask the other party to stop the infringement and compensate for the losses.
