Masimo Sues US Customs to Block Apple's Restored Blood Oxygen Feature on Apple Watch

Following a patent infringement lawsuit by Masimo, Apple's blood oxygen feature on the Apple Watch was initially banned. While Apple disabled the feature via software, it recently re-enabled it, calling it a "redesigned" feature. Masimo now alleges that US Customs and Border Protection (CBP) overstepped its authority and violated due process by allowing Apple to restore the functionality. The lawsuit seeks to prevent CBP's decision and reinstate the original ban. The central issue is whether CBP violated due process and whether Apple's 'redesigned' feature still constitutes patent infringement.
