A Trade Mark protection period is 10 years starting from the date of registration.
This period can be extended with a condition of being renewed for 10 month periods.
During the 10th year from the date of registration the application for renewal can be made 6 month before. If the term is missed, then an additional period of 6 months is granted to the owner of the registration. In case the additional period is also missed the Trade Mark becomes invalid.
