The use in the course of trade, for goods or services, not authorised by the proprietor of a well-known trade mark within the meaning of Article 6 bis of the Paris Convention for the Protection of Industrial Property, shall not constitute an infringement but shall give rise to civil liability on the part of its author:
1° Of a sign identical to the trade mark and used for goods or services identical to those for which the trade mark is well known;
2° Of a sign identical or similar to the trade mark and used for goods or services identical or similar to those for which the trade mark is well known, if there exists, in the mind of the public, a likelihood of confusion including the likelihood of association of the sign with the trade mark ;
3° Of a sign identical or similar to the mark and used for goods or services identical, similar or not similar to those for which the mark is well known, if such use of the sign, without just cause, takes unfair advantage of, or is detrimental to, the distinctive character or the repute of the mark.
