U.S. trade officials have ruled that South Korea's Samsung infringed on patents owned by Apple for specific smartphone features, ratcheting up a tit-for-tat legal battle between the two electronics giants that is matched only by the ferocity of their marketplace competition.
A U.S. trade agency says Apple infringed on its Asian rival Samsung's patent in its manufacture of some older models of the iPhone and iPad.
Bloomberg reports on the order from the U.S. International Trade Commission: "It's the first patent ruling against Apple in the U.S. that affects product sales, covering models of the iPhone 4, iPhone 3GS, iPhone 3, iPad 3G and iPad 2 3G made for AT&T Inc."
