ALLENS ARTHUR ROBINSON and Melbourne firm Davies Collison Cave have been recognised as the top firms in trademark and copyright work in an international poll conducted by Managing Intellectual Property. The ranking was established by feedback and nominations from more than 4,000 IP practitioners worldwide. Head of Allens’ IP practice group, Jim Dwyer, said the poll considered both law firms and specialist trademark attorney practices. The fact that such a large number of practitioners from around the world were surveyed was a significant commendation of the group, he said.
