Intellectual Property

When some of the world's leading brands need speed and clarity, they turn to Simpson Grierson. Why? Because we deliver decisive, commercial advice from recognised experts.

The depth of our intellectual property team sets us apart. It is double the size of any other commercial law firm in New Zealand.

This strength is reflected in our trade mark and design prosecution practices. These include portfolios for some of the world's leading brands. We are also sought out for some of New Zealand's most significant IP disputes and appeals.

Simpson Grierson's other practice areas regularly seek our IP expertise, including our mergers & acquisition specialists who have advised on some of New Zealand's largest commercial transactions.

We are highly ranked as a leading IP practice in the major international directories, Asia Pacific Legal 500 and Chambers Global.
