FORTUNE — Six months after a jury awarded Apple (AAPL) $1.05 billion in its landmark patent infringement suit against Samsung, the judge in the case finally sorted through the paperwork and issued what amounts to a split decision.
In a 27-page order released Friday, Judge Lucy Koh vacated $450 million of the original award and ordered a new trial to sort out how much Samsung should pay for 13 devices where the jury’s math is in dispute.
“When a Court detects an error in the jury’s damages verdict,” she wrote, “the Court has two choices: the Court may order a new trial on damages, or the Court may reduce the award to a supportable amount.”
On Friday she did both, reducing Apple’s award to cover 14 of the devices at issue and ordering a new trial on the other half.
Apple can now demand that Samsung pay the nearly $600 million of the award that the judge let stand, plus whatever the court decides to add in terms of interest and supplemental damages from Samsung’s sales.
But since the case is headed for an appeals court, both the new damages trial and the $600 million check may have to wait.
