The U.S. Patent and Trademark Office has issued a preliminary decision that rejects all 44 claims Blackboard Inc. made regarding the controversial patent it was granted for an online-learning system. The case could have major ramifications for the ongoing lawsuit between Blackboard and Canadian-based Desire2Learn.
Last year, I wrote about a patent lawsuit launched by Blackboard against Waterloo-based Desire2Learn. On Friday, a jury in Texas ruled against the Canadian company, awarding $3.1 million in damages.
Last month I wrote about the patent battle between Blackboard and Canada's Desire2Learn. Desire2Learn has just filed its response in the Texas court.
So begins my weekly Law Bytes column (Toronto Star version, BBC International version, homepage version) which does not discuss the RIM-NTP patent suit but rather the recent patent lawsuit launched by Blackboard, a learning management system company, against Desire2Learn, a Canadian competitor. Both the patent and the lawsuit have generated enormous anger within the academic and open source software communities.
