Any person disputing a registered trademark may, within five years from the date of approval of the trademark registration, apply to the Trademark Review and Adjudication Board (TRAB) for adjudication. Where a trademark, before its being approved for registration, has been the object of opposition and decision, no application for adjudication may be filed based on the same facts and grounds.

Any interested party who is dissatisfied with the adjudication made by the Trademark Review and Adjudication Board may, within thirty days from the date of receipt of the notice, institute legal proceedings in the People's Court. The People's Court shall notify the other party of the trademark adjudication proceeding to be a third party to the legal proceedings.
