Their aim isn't money, however. They wish to have it stated in the courts that they are not violating any patents owned by Samsung, since that is how these shenanigans began. Samsung's original threats towards Wistron for supposed patent infringement, and if Wistron really believes themselves to be in the right it's no surprise that they would want it out in the open.
There has been no response from Samsung yet. It seems equally possible that they will fight back, or instead decide to let sleeping dogs lie.
