(Telecompaper) The US International Trade Commission (ITC) has ruled that Apple infringed on a Samsung patent involving the ability of devices to transmit multiple services through 3G technology, resulting in a ban on the importation or sale in the US of the iPhone 3GS, iPhone 4, iPad 3G and iPad 2 3G by AT&T, Reuters reports. President Obama has 60 days to decide whether to veto the ruling. The ruling overturned a September 2012 decision by ITC judge James Gildea, who had found that Apple did not infringe on patents at issue. The ITC found that Apple did not violate three other Samsung patents. Apple said it would appeal the decision.
