Blackboard patents invalidated

From Michael Feldstein, a follow-up to the Blackboard patent case I wrote about a few weeks ago: all of Blackboard's patents have been rejected in a ruling. Though there is still room for appeal, apparently the bar will be set very high and it's likely that this ruling will stand. It's good to see that patent system working correctly in this instance, but it would be nice it a company wouldn't need to go through such expensive and uncertain litigation to do something they should clearly have the right to do.
