If you’ve been wondering why Apple Watches banned in Masimo, you’re not alone. The news has sparked interest among tech lovers and health-conscious users alike. The ban is the result of a high-profile legal battle between Apple and Masimo, a medical technology leader known for its advanced health monitoring systems.
In this article, we’ll explain why Apple Watches banned in Masimo, which models are affected, how it impacts users, and what the future holds for Apple’s wearable tech.
The Backstory: Apple vs. Masimo

Masimo is a global medical technology company specializing in pulse oximetry, a non-invasive way of measuring blood oxygen levels. The company claims that Apple incorporated Masimo’s patented blood oxygen monitoring technology into certain Apple Watch models without authorization.
In January 2023, Masimo took legal action, arguing that Apple’s Blood Oxygen Sensor directly infringed on their patents. According to the Apple Newsroom, Apple denied wrongdoing but prepared for potential changes in its product lineup.
Why Apple Watches Banned in Masimo
The U.S. International Trade Commission (ITC) investigated the dispute and sided with Masimo. As a result, the ITC issued a ban that stopped the import and sale of specific Apple Watch models in the United States and influenced availability in some other regions.
Apple Watch models affected by the Masimo ban:
- Apple Watch Series 9
- Apple Watch Ultra 2
- Any models containing the disputed blood oxygen technology
