If the registrant complains to the industrial and commercial administration department and requests protection of his trademark exclusive rights, he should submit a written complaint application and attach his valid supporting materials, including: First, the complaint letter (including the object of the complaint, Complaint matters and requirements, rights holder or complainant contact information). The second is the rights status of the trademark owner (trademark registration certificate). Third, pictures of the actual use of the trademark (including pictures of the right holder’s actual use of his own trademark and pictures of the actual use of the respondent’s product trademark). Fourth, for foreign-related trademarks, corresponding notarization and certification materials must be issued in accordance with regulations. Fifth, for the seized items involved in the case, the industrial and commercial administration department may require the right holder (including an authorized agent) to provide identification opinions on whether the goods involved are products produced or licensed by the right holder. After the industrial and commercial administrative department files a complaint against a trademark registrant and handles it, it shall notify the complainant of the handling results. This enables complaints about trademark registration and infringement.
