Voxson Pty Limited v Telstra Corporation Limited

Voxson Pty Limited filed a claim against Telstra Corporation Limited in relation to patent infringement. Voxson alleged that Telstra infringed its patent by using a system for location determination that was protected by a patent. Telstra sought to strike out Voxson's amended statement of claim on the basis that it was not sufficient in law and should be struck out. The central issue before the court was whether leave should be granted to Voxson to amend its statement of claim, and if so, whether the amendments were minor or substantial. The court considered whether the amendments were reasonable given the iterative process of amendments that had occurred up to that point and the respondents' conduct.

The court found that the amendments were substantial but necessary to accurately plead the case. The court noted that the iterative process of amendments had been driven by the respondents' need for clarity and particulars. While the respondents had argued that the amendments were minor, the court found that the proposed amended pleading had significantly changed the case being made. The court was satisfied that the amendments were not an abuse of process and that the respondents had not been prejudiced by the amendments. The court also found that the respondents' conduct had been unreasonable, as they had not raised certain issues until late in the proceedings. The court concluded that leave should be granted to Voxson to amend its statement of claim, and that appropriate costs orders could be made without a successful strike out application.

The court ordered that leave be granted to Voxson to file an amended statement of claim by a specified date. The court also ordered that the parties confer to discuss the further conduct of the proceeding and notify the court of the proposed orders. The court's decision highlights the importance of allowing parties to amend their pleadings where necessary to accurately plead their case, particularly where the respondents' conduct has driven the need for amendments. The court also emphasised that appropriate costs orders can be made without a successful strike out application.
