On August 21, health technology giant Masimo filed a lawsuit against the United States Customs and Border Protection (CBP), alleging that the agency illegally permitted Apple to reactivate a blood oxygen monitoring feature on the Apple Watch, which Masimo claims infringes on its patents. Prior to this development, a patent dispute had led to a ban on Apple selling watches equipped with this feature in the United States. Nevertheless, Apple circumvented the ban by updating its software to transfer blood oxygen measurement calculations to the iPhone. Masimo contends that CBP reversed its previous decision without consulting Masimo, thereby causing harm to its interests.
