Thank you DangerousDave. Somebody at my research office put me in touch with the legal person who drew up our University IP policy. If that fails, I will do what you say, it sounds like a good idea. If I can't get anywhere with the Admin people, how can I contact you for those model contracts? Shall I open a new thread with your name on the title on the forum, or will you be keeping an eye on this thread? Thank you again.
