Ireland acceded the London Agreement

Ireland acceded the London agreement and dispensed the translation requirement of European patents granted in German or French. Thus, Applicants of European patents do no longer have to file an English translation with the Irish Patents Office in order to validate European patents for Ireland, which were granted on or after September 3, 2012 (also, European patents, for which the mentions of grant were published in the 6 months prior to September 3, 2012, are no longer treated as void) .
