The US smartphone giant, Apple, has won a key case in a long running patent war against rival Samsung.
The US International Trade Commission upheld a 2011 decision that South Korea’s Samsung infringed Apple patents when producing mobile phones, media players and tablets.
The Commission has ordered a ban on imports of Samsung devices affected by the ruling.
Samsung said it was disappointed at the decision.
The ban is now on hold while US President Barack Obama reviews the decision within the next six months.
