On Monday, the US International Trade Commission (ITC) dismissed a complaint by Google-owned Motorola Mobility accusing Apple of infringing on patented technology that makes touchscreens ignore fingers when people are holding smartphones to their ears for calls.
The filing by acting ITC secretary Lisa Barton indicated that the investigation into the Motorola complaint filed in late 2010 has been terminated.
The ITC reasoned that the technology at issue in the patents wasn't original enough to support the accusation.
Competition between technology titans such as Apple, Google, and Samsung long ago spread to the courts in the battle for supremacy in the booming markets for smartphones and tablet computers.
A judge last month cut $450 million from a $1 billion award to be paid by Samsung in a landmark patent lawsuit from Apple, saying a jury had wrongly calculated the damages.
