Recent documents made public have shed light on the intricate details of the import ban on Apple Watch Series 9 and Apple Watch Ultra 2, specifically focusing on the contested pulse oximeter feature. Initiated in January, the ban prompted much speculation regarding its breadth and Apple's countermeasures. Apple's temporary solution—disabling the pulse oximeter functionality via software updates—raised questions about the fix's permanence and the conditions under which the feature might be reinstated.
The U.S. Customs and Border Protection's update provided clarity, revealing that Apple's software-based disablement of the pulse oximeter allows for the possibility of reactivation in future updates. This insight came amid debates, particularly highlighted by Masimo's contention that Apple's workaround was insufficient. Masimo demonstrated the feature's reactivation on a jailbroken iPhone, challenging the permanence of Apple's solution. However, Customs found the argument of jailbreaking—an action that significantly alters the device's original system—insufficient to invalidate Apple's temporary fix.
The disclosed documents elaborate that the pulse oximeter is deactivated through specific software "designations" that Apple can technically reverse, restoring the device's original functionality. Nevertheless, the possibility of reversing this software limitation is contingent upon Apple successfully appealing against the ban or awaiting the expiration of the contested patents in August 2028. With appeals already underway, the timeline for resolution remains uncertain, reflecting the often-protracted nature of legal proceedings within the U.S. judicial system.
This development was first reported by ip fray, marking a significant update in the ongoing saga surrounding the Apple Watch's features and the legal challenges confronting them.
