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 EU 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 to apply for a declaration that the later trade mark is invalid in respect of the goods or services for which the later trade mark has been used, unless registration of the later EU trade mark was applied for in bad faith.
I gcás inar thoiligh dílseánach trádmhairc is túisce amhail dá dtagraítear in Airteagal 8(2) nó dílseánach comhartha eile is túisce dá dtagraítear in Airteagal 8(4), ar feadh tréimhse cúig bliana as a chéile, le trádmhairc is déanaí de chuid AE a bheith in úsáid sa Bhallstát ina bhfuil an trádmharc níos luaithe nó an comhartha níos luaithe faoi chosaint, agus é ar an eolas faoin úsáid sin, ní bheidh an dílseánach sin i dteideal a thuilleadh iarratas a dhéanamh, ar bhonn an trádmhairc níos luaithe nó an comhartha eile níos luaithe, ar dhearbhú go bhfuil an trádmharc níos déanaí neamhbhailí i leith na n-earraí nó na seirbhísí dá raibh an trádmharc níos déanaí in úsáid, murar rinneadh an t-iarratas ar an trádmharc de chuid AE a chlárú de mheon mímhacánta.
