39. Revocation

This chapter examines revocation as a reason for removing a mark from the register and the grounds for revocation as set out in section 46 of the Trade Marks Act 1994 and Article 57 of the European Union Trade Marks Regulation. It begins by discussing the first ground on which a mark may be revoked: ‘non-use’ (the trade mark has not been used for five years following the date of completion of the registration). It considers the relevant period of non-use and proper reasons for non-use, along with the issue of rewriting the specification with respect to goods and services. The chapter then looks at the second ground for the revocation of trade marks: if the mark has become the ‘common name in the trade’ (that is, generic marks). The final reason for revocation is if the mark has been used in a way that misleads the public (that is, deception is involved).
