incompatible avec la GPL !

quand à la GPL: http://www.gnu.org/licenses/gpl.txt 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. Donc si un brevet, comme autorisé par le W3C, empeche de modifier le programme de la façon dont on veux, ce qui contredit la GPL, alors je n'ai pas le droit de distribuer un tel programme contenant du code protégé par la GPL et dont je n'ai pas le copyright.
