You're probably talking about
Barnes & Noble. But while they're fighting it, the case isn't over yet. Microsoft is also suing Motorola and got a
preliminary ruling from the ITC that Motorola was in violation.
I haven't read the 43-page filing Barnes & Noble made, nor the patents in question, so I can't weigh in on the value of the patents. (The summary quoted is never a useful tool to dismiss patents, you have to read all the details.)
It is a good point that LG has licensed the patents SINCE the response from B&N, so they must think there's value to it.
