Article 1 - EU trade mark
‘1. A trade mark for goods or services which is registered in accordance with the conditions contained in this Regulation and in the manner herein provided is hereinafter referred to as a ‘European Union trade mark (“EU trade mark”)’.
2. An EU trade mark shall have a unitary character. It shall have equal effect throughout the Union: it shall not be registered, transferred or surrendered or be the subject of a decision revoking the rights of the proprietor or declaring it invalid, nor shall its use be prohibited, save in respect of the whole Union. This principle shall apply unless otherwise provided for in this Regulation.‘
Article 4 - Signs of which an EU trade mark may consist
‘An EU trade mark may consist of any signs, in particular words, including personal names, or designs, letters, numerals, colours, the shape of goods or of the packaging of goods, or sounds, provided that such signs are capable of:
(a) distinguishing the goods or services of one undertaking from those of other undertakings; and
(b) being represented on the Register of European Union trade marks (‘the Register’), in a manner which enables the competent authorities and the public to determine the clear and precise subject matter of the protection afforded to its proprietor.‘
