Fast-food giant McDonald’s has filed a trademark infringement notice in the Federal Court against Hungry Jack’s Australia burger ‘Big Jack’.
Hungry Jack’s double-layer hamburger was unveiled in July, but its US archrival alleges it has a similar appearance to the Big Mac. McDonald’s filed the case on August 28, according to a report in The Sydney Morning Herald.
Hungry Jack’s “deliberately adopted or imitated” the “distinctive appearance or build” of the Big Mac, McDonald’s claims, pointing out it also has two all-beef patties, a special sauce with lettuce, cheese, pickles, onions and is made with a sesame-seed bun.

The Australian chain’s burger has two flame-grilled 100-per-cent Aussie beef patties that has melted cheese on top with special sauce, fresh lettuce, pickles and onions sandwiched in a toasted sesame-seed bun.
“Hungry Jack’s has not been served any formal documents from the court and, thus, is unable to provide any comment at this stage,” the company said in a statement.
McDonald’s is seeking damages and ordered Hungry Jack’s to destroy all promotional materials.
