IANAL either, but I don't think this is correct -- patents and copyrights (licenses are implemented using copyright law) are more-or-less orthogonal. Just because something is patented doesn't mean it cannot be released under an open source license. You can have and distribute the source code, but you might need to seek a patent license to actually use the code. One example of this I know about is the marching cubes algorithm in VTK (although that patent has now expired). GPLv3 may explicitly deal with this issue, but I think GPLv2, BSD and MIT licenses don't. -Andrew --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
