McDonald's loses its case against Hungry Jack's after a court finds the Big Jack burger is not "deceptively similar" to the Big Mac, following a trial in which experts were called in to examine the products.

  • A court has ruled a Hungry Jack’s burger did not infringe on McDonald’s trademark.

  • McDonald’s argued its rival’s product could confuse consumers and eat into its profits.

  • A scientist was brought in to weigh the two-patty burgers over the three-year trial.

McDonald’s has lost its legal dispute with fast-food rival Hungry Jack’s over its Big Mac lookalike burger the “Big Jack”.

The American giant had claimed that consumers would confuse the Big Jack with the Big Mac and this would eat into McDonald’s profits.

But Justice Stephen Burley ruled against the claim in the Federal Court today.

“Big Jack is not deceptively similar to Big Mac,” Justice Burley said.
