Ann: RFX AGM CEO's Address to Shareholders, page-6

Sorry QLD Uni. I thought it was you however it was NSW Uni it seems.

UNSW filed a patent in 1986 and a 200kW/800kWh system installed in Japan was the first large-scale implementation of the technology.

In the late 1990s, UNSW sold the patent to an Australian company, Pinnacle Renewable Energy, which failed to commercialise the product. That original patent passed through a series of corporate owners before expiring.
