Arguendo (931986) writes "A federal appeals court today ruled that Blackboard Inc.'s patent on a learning management system is invalid in light of the inventors' own prior software product. We have previously discussed the patent and Blackboard's trial court victory against Desire2Learn. It's not completely over, but this is almost certainly the death knell for Blackboard's patent. If so inclined, you may read the appellate court's decision here (pdf) or on scribd here."
