After the application for trademark registration is submitted, our bureau will issue an acceptance notice about 1 month; The notice period of preliminary examination is 3 months; It takes about 1 year to complete trademark registration. Because trademarks are artificially examined, the law does not clearly stipulate the examination time. Except for the statutory time limit of 3 months for the announcement period of preliminary examination, all other times are estimated time, because the law does not clearly stipulate the completion time of trademark examination, and ultimately the completion time of trademark office shall prevail.
