PTO Has Rejected All 44 Of Blackboard's Patent Claims

From the Desire2Learn Patent-Information Blog:

On March 25, the U.S. Patent & Trademark Office issued its Non-Final Action on the re-examination of the Blackboard Patent. We are studying the document, found here, but in short, the PTO has rejected all 44 of Blackboard's claims. We caution that this is a NON-final action; both Blackboard and Desire2Learn will have an opportunity to comment before a final action will issue, and after that, the decision will be subject to appeals.

However, we're still pleased.
