re: #59 Belafon

I think they should be at 25 years after creation, 35 at the most. That’s long enough that a work like Harry Potter would lose most of it’s monetary impact if a movie studio tried to wait out the copyright before making a movie.

Maybe it’s because I’m a(n aspiring) writer with too much of a legal education, but my only concern is opening up works to derivative works during the life of the author. Under your formulation, at 25 years, A Song of Fire and Ice (Game of Thrones) would fall into the public domain in 5 years time. But it seems GRRM still has plenty more work in that realm.
