Trademark registration can be carried out in the following ways:

1. Self-service registration: Trademark offices in some countries or regions provide an online self-service registration system through which applicants can fill in the form themselves and submit a trademark registration application. Self-service registration usually requires providing trademark drawings, trademark descriptions, applicant information and other relevant information.

2. Trademark agency: A trademark agency is an agency that specializes in providing trademark registration agency services. Applicants can entrust a trademark agency to act as an agent for trademark registration applications. Trademark agencies will help applicants prepare and submit application documents, and assist with subsequent reviews and procedures.

3. Lawyer or legal adviser: Applicants can also seek help from lawyers or legal advisers and entrust them to act as agents for trademark registration applications. A lawyer or legal consultant will provide legal advice and representation services to ensure that the applicant's trademark registration application meets legal requirements.

It should be noted that the specific trademark registration methods may vary depending on the trademark regulations of the country or region. When choosing a trademark registration method, applicants can choose the most suitable method to apply for trademark registration based on their own circumstances and needs.
