All 44 Blackboard Patent Claims Invalidated

Posted by ScuttleMonkey on from the small-victories-still-victories dept.

I Don't Believe in Imaginary Property writes "The US Patent & Trademark Office has invalidated all 44 claims in Blackboard's patent. While this is a non-final action [PDF], which means that Blackboard will be able to appeal, it does represent a win for the Software Freedom Law Center which had requested the reexamination of Blackboard's patent. It is not yet known how this will affect the $3.1M judgment Blackboard won from Desire2Learn."
