Group 1: Legal Dispute - Masimo has filed a lawsuit against CBP in federal court, claiming that the agency reversed its previous decision regarding the importation of Apple Watches with blood oxygen reading capabilities without notifying Masimo [3]. - The conflict between Masimo and Apple has been ongoing, with Masimo accusing Apple of poaching its employees and stealing technology for the pulse oximeter used in Apple Watches [3]. - In 2023, Masimo successfully convinced the U.S. International Trade Commission (ITC) to block the import of Apple Series 9 and Ultra 2 smartwatches due to patent infringement related to blood oxygen level reading technology [3]. Group 2: Recent Developments - On August 14, Apple announced it would reintroduce the blood oxygen reading feature in its smartwatches, contingent upon CBP's approval, which Masimo argues was granted without proper consultation [3]. - Masimo contends that CBP's actions undermine its rights and responsibilities, emphasizing that the agency should enforce the ITC's exclusion order rather than create loopholes [3]. - Masimo is seeking a court order to halt CBP's decision and prevent Apple from selling watches with blood oxygen functionality [3].
