This is not what happened, they had the trademark for "Big Mac". They took Supermac's to court because their name was too similar, and ended up losing the trade

This is not what happened, they had the trademark for "Big Mac". They took Supermac's to court because their name was too similar, and ended up losing the trademark. For a while Burger King Sweden was selling burgers using the name, apparently the "Anything But a Big Mac", "Burger Big Mac Wished it Was", etc.
