Among other complaints, Samsung's original counter-suit alleged that nVidia infringed upon technical patents detailing cache control.
The US International Trade Commission just recently announced that it will move forward with an investigation into nVidia's operations. A similar result is expected from the ITC regarding Samsung (stemming from nVidia's own lawsuit against the company).
Nothing will come of this for years yet, but we'd anticipate a settlement of sorts long before any public resolution.
