Enter the WIPO notification date and select designated countries. TEAL shows the 12 vs. 18-month refusal window for each — the date by which the national office must issue a provisional refusal or protection is granted automatically.
Provisional Refusal Deadlines
The refusal window runs from the date WIPO notifies the designated Contracting Party (the IB notification date), not from the international registration date or filing date. If no provisional refusal is issued within the window, protection is granted automatically in that jurisdiction. Always confirm with WIPO Madrid Monitor for official dates.
