USPTO Invalidates all 44 of Blackboard's Patent Claims
While this is still a non-final action, e-Literate is reporting that the USPTO has invalidated all 44 of Blackboard's patent claims for their LMS patent granted back in 2006 Since the original patent grant, Blackboard has been swinging the hammer pretty hard for claims that I considered were certainly in the "Duh!" factor of obviousness not to mention prior art. Let's hope that any appeals by Blackboard fail.
