A copyright work exists upon its creation and is not subject to any formal requirements such as registration or fixation. Therefore any literary and artistic creations of the mind enjoy copyright protection if they embody an intellectual creation with a sufficiently individual character. An official deposition or registration of the copyright work is not provided under Swiss Law. However, it is highly recommendable for reasons of evidence, that the author builds a record of documentation of his ideas, drafts and realizations. Such a documentation should made, if possible, during the whole creative process, as continuous as possible, because not only completed works, but also drafts and parts of a work are legally protected by copyright.
