Apple lost in Japan and Korea (Korean judge said that both companies used others patents). It was clear that Apple, which is based in the US, would win in US court over Korean based company - Samsung. Anyway, Apple hasn't won yet, they need to go through courts of appeals, which can take years.
It doesn't take a genius to read at the bottom of that ad... Says Samsung mobile USA. It's an ad based on USA and yes, they have been declared a shameless copycat in the USA.
