What to do if an international registration has expired
Transform it to a new Section 1 or 44 application
An international registration is dependent on the basic application and/or basic registration for five years after the date of the international registration. See TMEP §1904.09.
If the IR becomes cancelled after 5 years, an owner can transform the IR into a new US Trademark application under or §1 or §44 of the Trademark Act.
While the new application maintains priority filing date, the transformation request must be filed within three months after the date on which the Article 6(4) cancellation was processed by the IB.The USPTO form is accessible under Madrid Protocol forms, “Transformation request” No. 5.
Upon filing a new application under §1 or §44, the examining attorney must conduct a new search to determine whether any later-filed applications for conflicting marks were approved for publication or registration and place the search strategy in the record. So, while the mark went through once, it will be subject to examination and may be refused, and have to be argued, etc.
USPTO filing fees are $350 USD per class.
