Article summary

Dispute Resolution analysis: Gordon Harris, head of the intellectual property team at Gowling WLG, examines the decision in Anan Kasei Co Ltd and another v Molycorp Chemicals & Oxides (Europe) Ltd to allow an application by the claimant proprietors of a European patent to join the infringing defendant’s parent company as a second defendant for the trial of quantum. The court also permitted the claimant to amend their claim form to allege the parent company’s joint liability and to service out of the jurisdiction on the parent company.
