A sign in Hungary may not be granted trademark protection: with respect to identical goods or services, if the sign with the later date of priority is identical with an earlier trademark; if because of its identity with or similarity to the earlier trademark and the identity or similarity of the goods or services there exists a likelihood of confusion on the part of the consumers; with respect to dissimilar goods or services if the sign with the later date of priority is identical with or similar to an earlier trademark having a reputation in the country where the use without due cause of the later sign would take unfair advantage of or be detrimental to the distinctive character or the repute of the earlier trademark.

A sign may not be refused trademark protection though even if it conflicts with an earlier trademark, which has not been used for the purposes of trademark Act, the likelihood of confusion includes the likelihood of association with earlier trademark.
