No problem. My copy of Autocad is owned by XYZ-software installation inc. A wholly owned subsidiary whose only asset is a copy of Autocad, I can sell the company to anyone I want - the license is never transferred.
[EDIT: Autodesk's EULA is one such - see section 9.1 in http://images.autodesk.com/apac_sapac_main/files/autocad_200...]
