Rights-holders can offer licences for use and distribution. This can be in the form of a creative commons licence or commercial licence.
The creative common licence is free of charge.
Commercial licences can be exclusive or non-exclusive.
In both cases, the licensor permits the licensee to use intellectual property in return for compensation. With regards to an exclusive licence, both parties agree that no other person can use intellectual property rights except the licensee. Regarding a non-exclusive licence, intellectual property can be used by multiple licensees.
