Old Digger Pty Ltd (formerly called SDS Digger Tools Pty Ltd) v Azuko Pty Ltd [2002] FCA 1158

The judgment dismissing the cross-claim for revocation of the patents constitutes a final judgment. The respondents had every opportunity to raise all grounds for invalidity, including under s 40 of the Patents Act, at trial; the validity of the patents as against the respondents is res judicata. The Court has no power to re-open the cross-claim nor to permit a new cross-claim on grounds arising from the same facts; issue estoppel and Anshun estoppel also apply to bar the respondents from advancing new grounds for revocation.
