A licence agreement means that the licensor grants the licensee the right of use for something protected by his property right. Subject of the licence agreement may be copyrights, patents, trademarks and similar. The right of use is usually provided against payment of a licence fee. One should distinguish between simple and exclusive licences. While under a non-exclusive licence the licensee may only partially use its object alongside the property right holder, under an exclusive licence the licensee is the only one to use the object in its total. Licences are usually included in contracts under General Terms and Conditions. To avoid disputes, the precise scope of the licence should be clarified at the stage of preparation of the contract.
