Since the Thai Trademark Act (No.3) came into force on July 28 2016, it has been possible for trade mark owners to file applications to renew their registrations within six months after the relevant expiration date subject to an official fee increase of 20 per cent. This six month renewal grace period has been of great benefit to many owners of trade mark registrations in Thailand. However, if the registered owner has merged into another entity before the renewal period, this merger needs to be recorded along with the late renewal.
