Trademark Act Article 60

Effect of sustained invalidationWhere invalidation against a registered trademark is sustained, such registration shall be cancelled. However, if the circumstance on which the trademark is not registrable no longer exists, a disposition to overrule such invalidation may be rendered upon considering the need for proportionality between the interests of the public and the interests of the concerned parties.
中文原文 商標法第60條
評定案件經評定成立者,應撤銷其註冊。
但不得註冊之情形已不存在者,經斟酌公益及當事人利益之衡平,得為不成立之評定。
