What is Invalidation? How to file the application for invalidation of trademark?
Where the registration of a trademark violates provisions of paragraph 1 of Article 23 or paragraph 4 of Article 59, a concerned party or a trademark examiner may request or inquire the Registrar Office to invalidate the said registration.
Whether a trademark to be invalidated to be invalidated violates the law shall be determined by the provisions of the law in effect at the time of publication for trademark registration.
A trademark invalidation shall be examined by three or more invalidation committee examiners appointed by the head of the Registrar Office.
Registration of a trademark of which invalidation was affirmed shall be invalid. No one shall request for an invalidation based on the same fact(s), the same evidence(s), and the same ground(s) against a trademark of which an invalidation decision was affirmed.
