The trademark owner shall register the trademark with the National Industrial Property Association. Before registration, it is necessary to carry out a prior investigation of the trademark in order to understand whether there is a registered trademark in the same business scope. But the procedure is not mandatory. The appropriate application documents may be used in applying for a registered trademark, on which the trademark and the relevant information of the applicant shall be recorded. The applicant may go to the headquarters, branch offices or representative offices of the State Industrial Property Office to carry out prior investigation of the trademark registration.
