As for the patent itself, it basically describes the rather obvious process of associating a piece of data with multiple categories. It's almost surprising that the company is suing Facebook instead of Google. While I'm not a heavy Facebook user, I'm not sure where Facebook uses such a system. Google, however, has made widespread use of a similar idea with its Gmail "labels." The idea is that rather than sorting data into a specific folder or category, it can be associated with multiple categories. If that seems rather obvious and ridiculously broad, well, that's the patent system for you these days.
