Most decisions have been made about the internet resorting to intellectual property law, copyright first, but also, and increasingly, trade mark law. These represent a twofold challenge: internet techniques involve two types of trade mark infringement. The infringement may first be restored by the unauthorised reproduction of a trade mark in information content, websites or discussion forums. This form of infringement is not new and the traditional rules of infringement are intended to penalise it. The second type of infringement gives rise to more debates, namely conflicts between domain names and protected trade marks. The rule which preside has the assignment of a domain name and that of ‘first arrive, first served’.
