06 Jun 2024 --- In a significant ruling, McDonald’s has lost a European trademark dispute to an Irish fast food chain over the name “Big Mac.” The European Court of Justice sided with Supermac’s in the long-winded legal battle and ruled that McDonald’s holds no exclusive right to use the label to refer to its chicken burgers sold in the EU. This ruling can have significant implications for both companies, potentially reshaping their branding and marketing strategies in the EU market.
