In April 2017, Irish fast-food chain Supermac's submitted a request to the European Union Property Office to cancel McDonald's owned trademarks within the European Union, claiming that McDonald's engaged in "trademark bullying; registering brand names... which are simply stored away in a war chest to use against future competitors", after the trademarks had prevented Supermac's from expanding out of Ireland. The EUIPO ruled in Supermac's favour, finding that McDonald's "has not proven genuine use" of many trademarks, cancelling McDonald's owned trademarks such as "Big Mac" and certain "Mc"-related trademarks within the European Union.
