Wimmera Industrial Minerals Pty Ltd v RGC Mineral Sands Ltd [1999] FCA 421

Wimmera Industrial Minerals Pty Ltd v RGC Mineral Sands Ltd [1999] FCA 421

Although RGC had not shown that the additional matters could not with reasonable diligence have been discovered earlier, the proposed amendments did not raise a new point in the relevant sense. RGC's prior process had been pleaded since November 1994, the amendments only broadened its alleged use geographically and temporally, and WIM had long been aware from its own patents and RGC's particulars that prior art included thermal oxidation followed by reduction. The proceedings were not close to trial, evidence had not been filed, and WIM would not be taken by surprise. Leave to amend was therefore granted, but a See v Scott-Paine order was refused.

Procedural Posture

Patent Infringement Proceedings With Cross Claim for Revocation / Interlocutory Application for Leave to Amend Particulars of Grounds of Invalidity and for a See V Scott Paine Order

Legal Issues

  1. 1 ['Whether RGC should have leave to amend paragraphs 2A(1) and 10A(1) of its Further Amended Grounds of Invalidity.' 'Whether a See v Scott-Paine order should be made if the amendment were allowed.' 'Whether the proposed amendments raised a new point that could justify allowing WIM to discontinue on costs terms.' 'Whether WIM would be taken by surprise by the amended reliance on prior use and prior art.']

Ratio Decidendi

Although RGC had not shown that the additional matters could not with reasonable diligence have been discovered earlier, the proposed amendments did not raise a new point in the relevant sense. RGC's prior process had been pleaded since November 1994, the amendments only broadened its alleged use geographically and temporally, and WIM had long been aware from its own patents and RGC's particulars that prior art included thermal oxidation followed by reduction. The proceedings were not close to trial, evidence had not been filed, and WIM would not be taken by surprise. Leave to amend was therefore granted, but a See v Scott-Paine order was refused.

Court Disposition

Leave to amend granted; See v Scott-Paine order refused; costs reserved for further argument.

Orders

  • ['The respondent have leave to amend paragraphs 2A(1) and 10A(1) of the Further Amended Grounds of Invalidity in accordance with exhibit PEZ 2 to the affidavit of Paul Edward Zawa sworn 2 October 1998.' 'Costs.']
