I'm not sure how much this lawsuit is based on a particular way of doing something - perhaps some code issues - or just a METHOD. 

Like Amazon's one-click patent - these type of patents are a travesty.  It's like patenting a walking path, getting from A to B.  As long as the code is not reused - (a lot of learning technology is based upon open specifications - look at IMS - so this type of patent is incredibly damaging to competition, in what is essentially a smaller enterprise market.

Now - how does this effect Integral?  Well, for one, there has been something launched at Integral Institute, called the Integral University.  While of course low on the totem pole - the broadness of the patents could conceivably put ANY online learning system in the crosshairs.
