In the validation phase, the European patent must be translated into the official languages of the states in which the patent proprietor is seeking protection.

For example, buried in the 2007 Annual Report issued by RWS Holdings is a statement concerning the impact of the London Agreement on RWS. The company estimated a reduction in profit before tax would be of the order of £1 million in the financial year ending 30 September 2008 and £2 million in a full year. Profits before tax for 2007 were over £10m - a hefty reduction - ouch!
