Kuuku I'yu Northern Kaanju homelands are centred on the Wenlock and Pascoe Rivers in Cape York. Their laws and creation stories are connected with their country. Through his father's bloodline, David Claudie knows the medicinal uses of plants that grow there.

The Chuulangun Aboriginal Corporation and the University of South Australia worked together to collect medicinal plants and test them in a laboratory. Together, they filed a patent application for a medicine developed from the plants.

The application acknowledges Mr Claudie as one of the inventors. The Aboriginal Corporation and University have an agreement for protecting the Indigenous Intellectual Property and sharing the commercial benefits.

Importantly, the traditional owners are driving the research and are partners in deciding how it is commercialised.
