Licences are generally granted under a contractual agreement (licence agreement) between the licensor (author or an owner of rights) and the user (licensee). The contract determines the rights of use and their scope granted to the licensee by the licensor. Basically, the licensor grants the licensee a manufacturing or distribution licence and/or a licence for use. The usage options can also be restricted; for example, by number (e.g. only a limited number of performances), by time (e.g. a film may only be shown in a cinema for a limited period) or by area (cf. Hilty, Urheberrecht, 2011, 267 et seq.).
