In the exclusive license contracts, licensor may not grant license to another person and unless the right has been apparently reserved, may not use the trademark himself.
(3) Unless otherwise agreed in the contract, licensors may not transfer their rights arising from the license to third parties or grant sub-licenses.

The licensee is obliged to comply with the terms of the license contract. Otherwise, the trademark proprietor may claim his rights arising from registered trademark against the licensee.
