We are ET.

ET Intellectual Property (formerly Ellis Terry) is a boutique intellectual property law firm, founded in 2009 by former partners of one of New Zealand’s oldest and largest intellectual property firms. Established to serve a local and international client base, but with a strong New Zealand client focus, we provide advice and expertise in all aspects of intellectual property.

We offer legal and strategic advice to innovative entrepreneurs, corporations, inventors, designers, and artists. Our patent attorneys are experts in mechanical, electrical, computer and software engineering.


While we judge our success by the clients we serve, we are proud to be recognised through industry awards.
