Article 54

Where the proprietor of a Community trade mark has acquiesced, for a period of five successive years, in the use of a later Community trade mark in the Community while being aware of such use, he shall no longer be entitled on the basis of the earlier trade mark either to apply for a declaration that the later trade mark is invalid or to oppose the use of the later trade mark in respect of the goods or services for which the later trade mark has been used, unless registration of the later Community trade mark was applied for in bad faith. Where the proprietor of an earlier national trade mark as referred to in Article 8(2) or of another earlier sign referred to in Article 8(4) has acquiesced, for a period of five successive years, in the use of a later Community trade mark in the Member State in which the earlier trade mark or the other earlier sign is protected while being aware of such use, he shall no longer be entitled on the basis of the earlier trade mark or of the other earlier sign either to apply for a declaration that the later trade mark is invalid or to oppose the use of the later trade mark in respect of the goods or services for which the later trade mark has been used, unless registration of the later Community trade mark was applied for in bad faith. In the cases referred to in paragraphs 1 and 2, the proprietor of a later Community trade mark shall not be entitled to oppose the use of the earlier right, even though that right may no longer be invoked against the later Community trade mark.
