I haven't found out yet what happened with it.
Here's a 2010 update, in which the corporate restructuring interacted with the pre-existing lawsuit:

And perhaps most interesting of all, finally a class-action against the publishers and Apple:

Recently, Liberty Media offered to buy B&N, and then wound up putting a bunch of money in and getting a couple directors on the board. Who is Liberty Media? Well, you can read the wikipedia entry as well as I can. More importantly, here's the CEO:
http://en.wikipedia.org/wiki/John_C._Malone
"Malone is now the chairman of Liberty Media [2] and CEO of Discovery Holding Company."
And Discovery Holding Company bears some close but non-identical relationship to Discovery something-or-other of the patent lawsuit.

Let the wild and unfounded, rampant speculation begin.

Malone owns more land than Ted Turner -- and he's more on the forestry end of things. Not really surprising.
