Blackboard awarded another new patent

I learned that Blackboard was granted a new patent (#7,493,396) on February 17, 2009. According to the patent, this is a continuation of their controversial "Internet-based education support system and methods" patent (#6,988,138) upon which their much-publicized lawsuit against Desire2Learn was based.

Can anyone explain the differences in these two patents?
