This came out at the beginning of August but I've just seen it now. In a nutshell: Oracle is backing Sakai, the open source LMS. Now, if we think about that for a second, we have here a pretty clear and unambiguous response from Oracle to the Blackboard patent, which was unveiled just four days before this announcement. And that response - which is actually unprintable in this newsletter - is, I think, more eloquent than anything else I could say here. More from a much more recent Sakai press release.
