Apple Ordered to Pay $184M Interest on $634M Masimo Patent Award
A federal judge rejected Apple's argument that the added interest on the Apple Watch blood oxygen sensor case would be a windfall for Masimo.
A federal judge ordered Apple to pay an additional $184 million in interest on top of the $634 million patent award already owed to Masimo over the Apple Watch blood oxygen sensor, according to AppleInsider.
In an October 5 ruling, Federal Judge James Selina rejected Apple's argument that adding interest would amount to a windfall for Masimo.
The payment is tied to the blood oxygen sensor patent trial involving the Apple Watch.
