McDonald's Corporation filed an opposition proceeding (TTAB91306242) against Jindilli International Holdings Pty Ltd's MACNUTTA trademark application before the USPTO Trademark Trial and Appeal Board. The opposition was filed on March 30, 2026, and marks the beginning of formal inter partes proceedings to determine whether the MACNUTTA mark should proceed to registration.

McDonald's Corporation, as the opposer, will need to establish its grounds for opposition (likely likelihood of confusion with its existing marks) and meet all TTAB procedural deadlines for discovery and testimony. Jindilli International Holdings Pty Ltd, as the applicant, must file a response to the Notice of Opposition within the timeframe specified in the Board's institution order. Failure to respond could result in default judgment. Both parties should engage trademark counsel experienced in TTAB proceedings to manage the case.
