New tool helps authors claim their copyrights back from publishers (even "perpetual assignments")

Under US copyright law, creators who have signed away their copyrights for the "full duration of copyright" can still get their rights back from publishers under something called the "Termination of Transfer," which is a hellishly complex and technical copyright provision that is almost never used, since it requires that creators wait decades and then successfully navigate all that complexity (even knowing how many years you have to wait is complicated!).
