"This is a win for Xbox customers and confirms our view that Google had no grounds to block our products," David Howard, a Microsoft deputy general counsel, said in a statement.
Motorola was "disappointed with this decision" and is evaluating its options, Motorola said in a statement.
In April 2012, ITC Judge David Shaw said in a preliminary decision that Microsoft infringed four patents and did not infringe on a fifth. But in June 2012, the trade panel sent the case back to the judge for reconsideration.
Google in January asked a trade panel to drop two patents from the complaint because they were essential to a standard.
In March, an ITC judge said that Microsoft did not infringe that technology and recommended that the case be terminated. The full ITC followed that recommendation on Thursday.
A different ruling could have barred the Xbox from being imported into the United States.
