Lawsuit ready to determine Anne Frank's Diary copyright

The copyright on Anne Frank's Diary may or may not expire tomorrow, January 1st, 2016. The Anne Frank Fund in Basel, Switzerland is threatening a lawsuit to keep the diary out of public domain a while longer, broadcaster NOS reports. The Swiss Anne Frank Fund holds the exclusive rights on the Diary and closely monitors its use. Copyright on texts expire on January 1st 70 years after the author's death. Anne Frank passed away early in 1945 in the Bergen-Belsen concentration camp. This means that her diary enters public domain on January 1st, 2016. The Anne Frank Fund, however, argues that Anne's father Otto Frank is co-author of the work, because he edited the diary after World War II. He passed away in 1980, which would mean that the copyright must remain in effect until 2050.
