Addisons has a multi-disciplinary IP and media team, with a particular expertise in the gaming sector both domestically and abroad. The team manages thousands of trade marks, and also directly manages and prosecutes trade marks in New Zealand and Papua New Guinea. The team has five partners including IP star Karen Hayne, Donna Short, Jamie Nettleton, Justine Munsie and Martin O'Connor. During the research period in a notable opposition proceeding, the firm acted for Challenger Group Holdings to oppose the registration of a trade mark for the word "CHALLENGER". In another contentious matter, the team is representing gaming company TSG against The Star Entertainment group over the registration of the mark "STARSWALLET". Partner Donna Short and special counsel Hazel McDwyer joined the firm from Henry Davis York during the research period. Short had led HDY's IP group.
