Ivax Pharmaceuticals (UK) Ltd v Astrazeneca AB [2004] EWHC 1264 (Ch) (28 May 2004)

Ivax Pharmaceuticals (UK) Ltd v Astrazeneca AB [2004] EWHC 1264 (Ch) (28 May 2004)

The presumption in favour of a stay was not rebutted by Ivax, as it failed to demonstrate sufficient commercial urgency or public interest to justify proceeding in parallel with the EPO. The potential prejudice to AstraZeneca regarding amendments and inconsistent decisions outweighed Ivax's arguments. The justice of the case did not require the English proceedings to continue.

Procedural Posture

Patent Revocation Action / Interlocutory Application for Stay of Proceedings

Legal Issues

  1. 1 Whether English patent revocation proceedings should be stayed pending EPO opposition outcomes
  2. 2 Whether justice requires refusal of a stay due to commercial prejudice or public interest

Ratio Decidendi

The presumption in favour of a stay was not rebutted by Ivax, as it failed to demonstrate sufficient commercial urgency or public interest to justify proceeding in parallel with the EPO. The potential prejudice to AstraZeneca regarding amendments and inconsistent decisions outweighed Ivax's arguments. The justice of the case did not require the English proceedings to continue.

Court Disposition

Stay granted

Orders

  • Proceedings stayed pending determination of the parallel EPO opposition proceedings
  • Liberty to apply to remove the stay if circumstances change, particularly if the EPO proceedings are not prosecuted with due diligence
