1905 Renewal of International Registrations
The term of an international registration is ten years, and it may be renewed for ten years upon payment of the renewal fee. Articles 6(1) and 7(1). Renewal of international registrations must be made at the IB, in accordance with Article 7 and Common Regs. 29 - 31. There is a renewal form, form MM11, on the IB website at http://www.wipo.int/madrid/en/.
The USPTO will not process a request to renew an international registration nor forward it to the IB. 37 C.F.R. §7.41.
The USPTO does not issue inquiries to the owner of a §66(a) application or registered extension of protection as to whether an international registration has been renewed. Under §70(b) of the Trademark Act, 15 U.S.C. §1141j(b), and Article 3 ter(2) of the Protocol, if the international registration is not renewed, the IB will notify the USPTO that the registration has expired. The USPTO will then cancel the registered extension of protection or abandon the §66(a) application as of the expiration date of the international registration.
