Class 30, what are the precautions for trademark registration? If a natural person, legal person or other organization needs to obtain the exclusive right to use a trademark for its goods or services in production and business activities, it shall apply to the Trademark Office for trademark registration. In a narrow sense, the application for trademark registration only refers to the application for trademark registration of goods and services, the application for international trademark registration, the application for certification trademark registration, the application for collective trademark registration and the application for special symbol registration. The application for trademark registration in a broad sense includes not only the contents of the application for trademark registration in a narrow sense, but also the application for alteration, renewal, transfer registration, objection application, cancellation application, trademark license filing and other trademark registration matters.
