To avoid a cancellation of a registered mark on the basis of non-use, the trademark owner must file an Affidavit of Use or Non-Use within one year following the fifth (5th) anniversary of the registration date/renewal date of the mark.
For filing a request for Affidavit of Use/Non-Use endorsement, the following documents are required :
(i) A Power of Attorney, which is signed by the Applicant and duly notarized;
(ii) An Affidavit of Use/Non-Use, which is simply signed by the Applicant. No notarization and/or legalization is required;
(iii) An original certificate of Trademark Registration, for endorsement purpose.
