If Microsoft tries to patent the Ribbon interface used in Office 2007, using tab views to allow the user to select certain tasks will be illegal. That's all the ribbon is - a nice-looking tab view with buttons and menus on it.
I'm not saying I think the Ribbon is a bad thing; I actually really like the Office 2007 Ribbon, even though it was not well-ported to Mac OS X in Office 2008. (I think that for Office 2008, they should have a menu for each tab in the Ribbon in Office 2007 and have the menu items be what's in the tab view (which is all the Ribbon is, a tab view, nothing more)). I just don't think Microsoft should patent it because then anything involving tab views could be taken as illegal patent copying or whatever term one would use for it.
This link probably has more info on the patent.

I have moved my blog to Wordpress at theunixgeek.wordpress.com. I will still be checking back periodically on this one as well, though. 19 April 2009
