In December 2016, the U.S. Supreme Court rejected the near $400 million judgement that Apple had won over allegations that Samsung copied iPhone-designed features used in its own phones. The sum, based on Samsung's profits from the sale of such phones, had already been whittled down through the courts from $1.05 billion that a jury awarded Apple in 2012. .

The fact that Apple is due financial damages from its South Korean rival—which has already paid $548 million to Apple—isn't in dispute at this retrial. What the justices effectively did was kick the case back down to the lower courts to have a jury decide how those damages will be calculated.
