Trademark holders that want to opt in for the Sunrise service are required to provide a Proof of Use (POU) of their submitted trademarks. As per the ICANN requirements, an update on the POU documentation is required once every five years. For this reason, the TMCH requires the holder (or the agent acting on its behalf) to reconfirm the validity of the submitted POU documentation.
This POU revalidation process is facilitated via the TMCH web interface and is detailled in this manual.
Note that the POU revalidation is a mandatory process for each sunrise eligible trademark record in the Trademark Clearinghouse.
