The provisions of Article 6, paragraph (3) do not apply, for six months from the day on which this Act comes into effect (or, if these companies change their trade names within that period, for the period until they change their trade names), to a special limited liability company prescribed in Article 3, paragraph (2) of the Act on the Arrangement of Relevant Acts Incidental to the Enforcement of the Companies Act (Act No. 87 of 2005), a stock company that continues to exist pursuant to the provisions of the first sentence of Article 66, paragraph (1) of that Act, or a general partnership company or limited partnership company that continues to exist pursuant to the provisions of the first sentence of paragraph (3) of that Article, in the case where, at the time this Act comes into effect, it actually uses in its trade name any word that is likely to cause it to be mistaken for a limited liability company.
