Any person may file an opposition to the registration during a two months period after the publication of the application in the Official Bulletin of Macao SAR.
A duplicate of the opposition is sent to the applicant. The applicant may respond to the complaint in writing, and it is to be filed within one month of the respective notification. Both parties are then given the opportunity, within certain time limits, to file evidence in support of the application and opposition. Once the period for the presentation of oppositions has expired, the IPD will proceed to the examination and study the proceedings, and decide upon the granting, or not, of the application.
