Overview

• Masimo filed suit in Washington, D.C., seeking a temporary restraining order and preliminary injunction to stop CBP’s new enforcement position.
• The complaint alleges CBP reversed a prior interpretation through an ex parte process without notice, exceeding its authority and violating due process.
• Apple announced on Aug. 14 a redesigned Blood Oxygen feature that shifts the final calculation to a paired iPhone and has issued iOS and watchOS updates to re‑enable it on Series 9, Series 10 and Ultra 2.
• An ITC ruling in 2023 found Apple’s pulse‑oximetry technology infringed Masimo patents and led to an import ban, after which Apple sold U.S. watches with the feature disabled.
• Apple’s appeal of the ITC exclusion order remains pending at the Federal Circuit, leaving the ultimate availability of the feature uncertain.
