Wimmera Industrial Minerals Pty Ltd v RGC Mineral Sands Ltd & Ors [1996] FCA 115

Wimmera Industrial Minerals Pty Ltd v RGC Mineral Sands Ltd & Ors [1996] FCA 115

The Court held that RGC's particulars of grounds of invalidity for lack of novelty and fraud/false suggestion were sufficient and aligned with the level of detail in the patent specification and established law; further particulars were not required except possibly for inutility, for which leave was granted to renew the application after evidence was filed. The interlocutory injunction restraining the Commissioner from extending the Petty Patent was refused on the balance of convenience.
