The court ruled that Samsung does not need to pay Apple $399m for copying some features on the iPhone, .
The case was around how much compensation should be paid under regulations from 1887 which say that anyone found to be infringing a patent must pay "total profits".
The BBC reported that the court said paying all profits was wrong as the parts that Samsung copied made up just a small element of its phones.
The case will move to a lower court to determine the level of compensation Samsung must pay.
