Gavin Doherty

Gavin is regarded as one of Australia’s foremost patent attorneys, having developed and managed world-renowned intellectual property (IP) portfolios for some of Australia’s most innovative international companies and has almost twenty years’ experience in international patent applications from both a regulatory and commercial perspective.

At Cochlear, the world leader in medical hearing devices, Gavin was responsible for all matters pertaining to Cochlear’s trademark and patent portfolio, including strategic portfolio review, ensuring optimal brand protection, and managing the prosecution of patents. During his time at Cochlear, the company was ranked the no. 1 Australian company in the Intellectual Property Research Institute of Australia Innovation Index and no. 3 for patent applications. At Orbital Engine Company, which licenses internal combustion engine technology globally, Gavin oversaw Orbital’s patent portfolio, one of the largest and most diverse patent portfolios in Australia.
