Who would have thought that trademark owners are a diverse bunch with divergent opinions? That is one of the more fascinating trends emerging from the study into the European trademark system. So it was pleasing to hear the researchers from the Max Planck Institute who are conducting the study acknowledge this when I met two of them earlier today. Roland Knaak, head of the research team, told me: "It is interesting for us to see the divergent opinions and positions of some of the user associations. Many have quite different opinions, for example, on the question of how further harmonization should be achieved."
