Pseudonymous Work  
  Anonymous and pseudonymous works are works in connection with which the true name of the creator is publicly unknown. In order to allow the creators of anonymous and pseudonymous works to get the full benefits of the protection by a copyright, it is possible to have an anonymous or pseudonymous work and the actual authorship thereof registered in the register of authors run by the German Patent and Trademark Office. Thus, not only the personal claim of the creator to the copyright relating to his work can be proved, but also the protection period of the work in question is extended in accordance with the Copyright Act.
