In such cases, where at least two designated goods relating to registration of the conversion of the classification of goods exist, a trial may be requested for each of the designated goods:
1. Where non-designated goods bearing the relevant trademark are registered for the conversion of the classification of goods, or the scope of designated goods has been substantially extended;
2. Where registration of the conversion of the classification of goods is obtained through an application filed by a person who is not the holder of the relevant registered trademark;
3. Where registration of the conversion of the classification of goods violates Article 209 (3).
(2) Articles 117 (2) and (5) shall apply mutatis mutandis to a trial to invalidate registration of the conversion of the classification of goods.
(3) Where the trial decision to the effect that registration of the conversion of the classification of goods is invalidated becomes final and conclusive, the relevant registration of the conversion of the classification of goods shall be deemed never to have existed.
