In Singapore, a registered trademark lasts for an initial period of 10 years from the date of application, and can be renewed for successive periods of 10 years each. The renewal application can be made within 6 months before the expiry date of the current registration or within 6 months after the expiry date, subject to the payment of additional fees.
It’s important to note that the trademark owner must use the trademark in Singapore in connection with the goods or services for which it is registered, and failure to do so for a continuous period of 5 years may result in the trademark being vulnerable to cancellation on the grounds of non-use.
Also, a trademark registration can be cancelled if it becomes vulnerable to revocation or invalidation. For example, if the trademark owner has not used the trademark for a continuous period of 5 years, if the trademark has become generic, if it is misleading or if it is in violation of public policy or morality.
Therefore, it’s important for trademark owners to monitor and maintain their trademark registrations to ensure that they are being used properly and are in compliance with the trademark laws and regulations in Singapore.
