Main-Line Corporate Holdings Ltd v United Overseas Bank Ltd: Patent Infringement & Interim Payment

Main-Line Corporate Holdings Ltd, an Irish company, sued United Overseas Bank Ltd (UOB) for patent infringement related to its Dynamic Currency Conversion system. The Court of Appeal allowed Main-Line's appeal, restoring the assistant registrar's order for UOB to make an interim payment of $1,962,424.30 directly to Main-Line, based on UOB's admitted profits from the infringing system. The court found that the judge had erred in not ordering interim payment, as there was reasonable certainty of a minimum sum recoverable.
