What is DAU? Do we have to submit DAU for a Philippine trademark?

DAU is short for “Declaration of Actual Use”. To maintain the registration of a Philippine trademark, the applicant must submit in time the required DAU together with use evidence. In absence of the DAU, the registered mark will be removed of registration and the trademark application will be refused of registration.
