High Court, on appeal from a decision of the Controller of Patents, determines that an Italian company was entitled to register the trademark 'Diesel' in respect of clothing, despite the fact that an Irish company had used the same name since 1979, the year after the Italian company started to use the name, on the grounds that: (a) the evidence established that an Irish company started to use the name in 1979, and not in 1978 as alleged; (b) the respondent was able to establish that it had purchased the name from the Irish company; (c) the key issues in the litigation were not res judicata, despite earlier litigation; (d) the copying of the name by the Irish company in 1979 had been dishonest and wrongful; and (e) there would be confusion and deception if both marks were to continue to be used in Ireland.
