Apple Watch’s restored blood oxygen tracking attracts another lawsuit

Here is a 200-word summary of the news article: Medical tech company Masimo is suing the US Customs and Border Protection (CBP) over its decision to allow Apple to restore blood oxygen tracking on Apple Watches. In 2020, Apple was embroiled in a legal dispute with Masimo over the latter's blood oxygen sensor patent. This led to an International Trade Commission (ITC) import ban in December 2023, forcing Apple to disable the feature on supported US Apple Watch models. However, the CBP recently reversed the ITC restrictions, enabling Apple to reactivate the blood oxygen tracking. Masimo claims it was not notified of this decision, denying the company the opportunity to review or challenge the ruling. Masimo believes Apple's "substantial investments in the United States" after its previous appeals were denied may have influenced the CBP's decision. Masimo is now seeking a temporary restraining order and preliminary injunction to prevent the new ruling, aiming to reinstate the original ITC ban that prohibited Apple from importing Watches with the infringing patent technology. The company argues that the CBP's actions have "irreparably deprived" it of its right to be free from unfair trade practices and preserve its competitive position in the US market.
