How are corrections to the International Register handled?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

Corrections to the International Register are handled as follows:

• The International Bureau (IB) may correct any error in the International Register.
• Corrections may be made ex officio or at the request of the holder.
• The IB notifies the holder and the offices of designated Contracting Parties of any correction.
• Offices have the right to declare that they refuse the effects of the correction.

According to MPEP 2930: “The International Bureau may, ex officio or at the request of the holder, correct any error concerning an international registration in the International Register.”
