Some information is being passed to me from various community members who have spoken with lawyers and am beginning to get a clearer picture of how the prior art must be framed. Note that this is all generic patent advice so far; I have no information yet about a lawyer’s analysis of Blackboard’s specific patent.

Since we’ve already reached the limits of the prior art documentation we can feasibly do within the bounds of Wikipedia’s mission, there is now room to add at the NoEduPatents.org wiki. Please note the drill-down to the Blackboard-specific area. Go to town, folks.
