cervesaebraciator (2352888) writes "Slashdot has reported before about the copyright nightmare of the 'I Have a Dream Speech'. Now questions of intellectual property and the legacy of Dr. King have caused his children to go to court. The estate, run by King's sons, claims the rights to the intellectual property and memorabilia of Dr. King as assets. Accordingly, it has filed suit against the non-profit Martin Luther King Jr. Center for Nonviolent Change, run by King's daughter, for plans to continue using King memorabilia once a royalty-free licensing agreement expires, (which the estate says will be in September). As is the case with increasing frequency, one is left to wonder about the implications intellectual property claims have for free speech when they can be applied to so public a figure as Dr. King."
