It's all integral

The Blackboard learning management system is looking decidedly uncomfortable after the pounding it has taken from large parts of the on-line learning sector over the past few days.
Trouble started when Blackboard sought, and was awarded, a US patent apparently covering most of what is widely known as an LMS (Learning Management System). Lots of institutions, companies and open source applications have developed various LMS solutions over the last several years, so you can understand them feeling a bit put-out.
Blackboard immediately filed a suit against a Canadian LMS company called Desire 2 Learn.
