Will I receive a postal reminder when my trademark’s legal protection is due to expire?

No. Holders of registered trademarks are not informed when the period of legal protection comes to an end. You should therefore take care to renew it within ten years of the filing date, before the protection period expires. After the ten years have expired, you will have a further six-month grace period in which to renew, but you will have to pay an additional charge equal to half of the usual renewal fee.
