Kirsch <SK @ MIT-MC> Subject: Apple gets patent on pull-down menus To: info-ibmpc @ USC-ISIB US Patent 4,464,652 granted to Apple Computer patents the use of a menu bar and sub-menus in conjunction with a mouse using "pull-down" style. I expect these patent claims will be challenged by Microsoft and IBM since Xerox Star had a pull-down menu in 1980 (the only difference here is that Star only had a single "icon" in its "menu bar"). ------- End of Forwarded Message ----------
