The specific department for trademark registration may vary from country to country, but generally speaking, trademark registration is usually managed and processed by an intellectual property office, trademark office, or similar government agency.

In China, trademark registration falls within the scope of the State Intellectual Property Office (now the Trademark Office of the State Intellectual Property Office).

In the United States, trademark registration is handled by the United States Patent and Trademark Office (USPTO).

In the European Union, trademark registration is managed by the European Patent Office (EPO) and the European Intellectual Property Office (European Intellectual Property Office, EUIPO).

Each country or region has established a specialized agency or department to manage trademark registration and is responsible for handling trademark application, review, registration and maintenance and other related matters.
