High Court rejects leave to appeal in patent case

On Friday 16 May 2008, the High Court rejected DuPont’s application for special leave seeking to appeal a finding of the Full Federal Court that ICI was not estopped from defending patent opposition proceedings brought by DuPont.

The opposed patent was a divisional application, the parent of which had previously been held invalid by Branson J of the Federal Court.
