US Patent Office rules against Blackboard
In the latest twist in the Blackboard patent case, the United States Patent and Trademark Office (USPTO) ruled all 44 of Blackboard's course management system patents were "rejected," according to Desire2Learn. All 44 are now subject to reexamination.
In response, Blackboard emphasized that this ruling is one step in a continuing process.
This Office Action was expected and is the first step in a reexamination process that often takes years to complete. It has no effect on the validity of the patent, the lawsuit between Blackboard and Desire2Learn or the pending injunction against Desire2Learn.
