Article 53bis of the Japanese Trademark Law corresponds to Article 6septies(1) and (2) of the Paris Convention, and Article 53ter of the Law corresponds to Article 6septies(3) of the Convention.
Where a trademark, subject to cancellation under Article 53bis of the Law, is well known, an application for registration of such a trademark should have been refused based on Article 4(1)(x) of the Law.
Accordingly, if the well-known trademark has been registered in bad faith, the five-year time limit provided for in Article 53bis is not applied and its registration may be invalidated at any time through appeal under Article 46 of the Law on the grounds that it is in violation of Article 4(1)(x) and obtained in bad faith, which is consistent with Article 6bis(3) of the Convention.
