You mixed patents with copyrights. RTLinux code is pure GPL, the
specific patents are dually licensed. FSMLabs (RTLinux creators)
gave an automatic non-revocable patent license to GPL'ed code
(so it won't infringe on the GPL). Other companies that try
to use the patented techniques in non-GPL code (e.g: in non-Linux
kernels) need to negotiate a *patent* license.
