Procedural Posture

Patent Revocation and Stay Application / Interlocutory Application for Stay Pending EPO Opposition

  1. 1 Whether to stay UK revocation proceedings pending EPO opposition outcome
  2. 2 Balance of justice between avoiding duplication and commercial certainty

Ratio Decidendi

The stay was refused because the EPO opposition proceedings were at an early stage and likely to be protracted, both parties were substantial commercial entities, the subject matter was of significant commercial value, and allowing the UK action to proceed would remove uncertainty and serve justice better than a stay, despite undertakings offered by Sanofi.

Court Disposition

Application for stay dismissed; costs to be assessed; trial to be fixed not before 16 April 2007; costs of CMC to be costs in the case.

Orders

  • Sanofi's application for a stay is dismissed.
  • Sanofi to pay GSK's costs of the application, to be assessed.
