Agreements are needed when these rights are used. Copyright arises upon creation of the work. First, ownership rests with the author or co-authors unless an exception concerning employment applies. An author is defined as a natural person. Related rights arise for performers and for producers of sound or film recordings. Performers are also defined as natural persons.
Producers, however, can be legal entities. Copyright consists of economic rights and moral rights. Reproduction right and the right of communication to the public are economic rights. The right of paternity and the right of integrity are moral rights. The author has to be named on all copies of the work and when a work is made available to the public, the right of integrity is the right of an author to prevent others from distorting mutilating or misrepresenting.
His work agreement is needed in order to use an author’s work. The right to further transfer copyright to third parties and the right to alter a work must be agreed explicitly. Otherwise, these rights are not transferred. There are exceptions to economic rights in the copyright legislation which allow illustration for scientific presentation and citation without permission or payment right of paternity and integrity also apply when economic rights do not so credit authors and sources and do not alter works.
