1.The rights of the proprietor of the Community trade mark shall be declared to be revoked on application to the Office or on the basis of a counterclaim in infringement proceedings:
(a)if, within a continuous period of five years, the trade mark has not been put to genuine use in the Community in connection with the goods or services in respect of which it is registered, and there are no proper reasons for non-use; however, no person may claim that the proprietor's rights in a Community trade mark should be revoked where, during the interval between expiry of the five-year period and filing of the application or counterclaim, genuine use of the trade mark has been started or resumed; the commencement or resumption of use within a period of three months preceding the filing of the application or counterclaim which began at the earliest on expiry of the continuous period of five years of non-use shall, however, be disregarded where preparations for the commencement or resumption occur only after the proprietor becomes aware that the application or counterclaim may be filed;
(b)if, in consequence of acts or inactivity of the proprietor, the trade mark has become the common name in the trade for a product or service in respect of which it is registered;
(c)if, in consequence of the use made of it by the proprietor of the trade mark or with his consent in respect of the goods or services for which it is registered, the trade mark is liable to mislead the public, particularly as to the nature, quality or geographical origin of those goods or services.
2.Where the grounds for revocation of rights exist in respect of only some of the goods or services for which the Community trade mark is registered, the rights of the proprietor shall be declared to be revoked in respect of those goods or services only.
