>> It's one of McDonald's best known burgers. But now a rival has won a case to prevent the fast food giant from trademarking the term Big Mac. The EU judgement in favor of the island based Super Macs revoked McDonald's registration of the trademark. It's said the world's largest fast food chain had not proven genuine use of it in the five years to 2017.
The ruling allows other companies to use the Big Mac name in the EU. Supermac's, which sells a burger called the Mighty Mac, say they can now expand in the UK and Europe. They say they've never had a product called Big Mac, but that McDonald's use the similarity of the names to block their growth.
McDonald's has a history of more successful litigation in trademark law. In 1993 they blocked a dentist in New York from selling services under the name McDental. And in 2016 they defeated an effort by a Singapore company to register the name McCoffee.
