14. Trade marks 2: definition of a registrable trade mark, absolute grounds for refusal and invalidation, and revocation

This chapter examines the definition of a registrable trade mark, absolute grounds for refusal or invalidation of a registered trade mark, the extent to which objections can be overcome through proof of distinctiveness acquired through use and the rules on revocation of a registered trade mark, both at national and EU levels. It examines these issues looking at many different kinds of trade mark, from traditional work marks and logos to so-called ‘non-conventional’ trade marks such as three-dimensional product shapes, sounds, smells, colours, and ‘position’ marks. The chapter reflects evolving legislation at an EU level (particularly the EU’s 2015 trade mark reform package), a rich base of case law, and links to the the theroetical debates seen in Chapter 13.
