However, the Judge also said that Samsung did not infringe portions of a second Apple patent that allows a device to detect if a microphone or other device is plugged into its microphone jack.
The commission will decide if they will uphold it or overturn the judge's decision. A final decision is expected in August.
If it is upheld, the ITC can order any infringing device to be barred from importation into the United States.
Apple had filed a complaint in mid-2011, targetting Samsung's Galaxy, Transform and Nexus devices, among others.
The case at the International Trade Commission is No. 337-796.
