"Use" is a concept which is fundamental to modern trade mark law, within the European Union, the US and elsewhere. The use concept is ubiquitous, since it must be understood before even basic issues of registrability, infringement and validity can be resolved. This book analyses the concept of "use" in trade mark law by tracing it at every stage of a trade mark's lifecycle. Topics covered include The Concept of Use, Registration, Exploitation, Infringement, and Death of a Trademark. It focuses primarily on European trade mark law, but also examines key aspects of US and international law. It is an invaluable information source if you or your client: (i) want to register a trade mark; (ii) are accused of infringing it; (iii) want to prove that, through use, the mark is entitled to remain on the register; (iv) want to make money from using the mark and (v) want to argue that another person's mark should not remain registered.
