The High Court has refused Sanofi and Wyeth special leave to appeal the Commonwealth’s claims on the clopidogrel undertaking as to damages.

You may recall that, when Sanofi and Wyeth got interlocutory injunctions to stop Apotex entering the market with a clopidogrel product, Sanofi had to give the “usual undertaking as to damages“. The patents, however, were held invalid.

Sanofi and Apotex settled the latter’s claim for damages. However, the Commonwealth also brought a claim against Sanofi and Wyeth under the undertakings as to damages, in broad terms claiming as damages the difference between the (higher) price it paid under the Pharmaceutical Benefits Scheme while the injunctions were in force and the lower price that would have applied if the interlocutory injunctions had not kept Apotex out of the market.

Last year, the Full Federal Court rejected Sanofi’s and Wyeth’s arguments that the Commonwealth could not bring a claim under the undertakings. Lauren John, an associate at Allens, reports that the High Court refused Sanofi’s application for special leave last week.
