6.2 Cancellation of the registration 

A registration of licences or other rights is cancelled upon request, supported by documents providing evidence that the right has lapsed or by the written consent of the proprietor of the right to the cancellation of that right. Rule 22(2) applies mutatis mutandis, i.e. the cancellation is subject to the payment of an administrative fee. Cancellation is only possible until publication of the mention of the grant.
