The Anne Frank Fonds in Switzerland is the owner of the copyrights on Anne Frank's world-famous diary.
However, a characteristic of copyrights is that they expire after 70 years of the death of the writer (in many countries) - in the case of the diary this will happen on January 1, 2016. Anne Frank's diary will then become public domain, and anyone can publish the text and do with it whatever they like.

To prevent this, the Anne Frank Fonds has tried to deposit 'Anne Frank' and 'Het Achterhuis' as a brand name with the Benelux brand name office. This was refused, upon which the Fonds appealed with a court of justice in Brussels. This court also denied the application for the brand names, in October 2013.
