In August the ITC gave its ruling on a matter that was put forward by Samsung. The Korean manufacturer claimed that Apple infringed on some of its patents, the ITC's ruling would have resulted in a formal ban on sales of some older iPhone and iPad models. The U.S. President has the power to review ITC's decision within 60 days and if he sees fit, he can veto the decision. That's exactly what the administration did in Apple's case, it vetoed the ban, but the same courtesy hasn't been extended to Samsung.
