Apple Watch’s Blood Oxygen Feature Restored After Legal Victory
Apple has achieved a significant legal victory in its ongoing patent dispute with medical technology company Masimo, leading to the restoration of the blood oxygen monitoring feature in its Apple Watch models. This development marks the culmination of a series of legal battles that have spanned several years.
Background of the Dispute
The conflict began in 2020 when Masimo accused Apple of infringing on its patents related to blood oxygen sensing technology. Masimo alleged that Apple incorporated this technology into its Apple Watch Series 6 and subsequent models without proper authorization. The dispute intensified in December 2023 when the U.S. International Trade Commission (ITC) imposed an import ban on certain Apple Watch models, including the Series 9 and Ultra 2, citing patent infringement.

Legal Developments and Apple’s Response
In response to the import ban, Apple took measures to comply with the ruling while continuing to serve its customer base. The company began selling modified versions of the affected Apple Watch models in the U.S., which had the blood oxygen monitoring feature disabled. This approach allowed Apple to maintain its market presence while adhering to the legal constraints imposed by the ITC.

The legal landscape shifted in March 2026 when the ITC ruled in favor of Apple, determining that the company’s devices did not infringe on Masimo’s patents. Masimo’s subsequent appeal to reinstate the ban was rejected, effectively closing the case. This decision paved the way for Apple to restore the blood oxygen monitoring feature in its Apple Watch models sold in the U.S. ([techradar.com](https://www.techradar.com/health-fitness/smartwatches/apple-says-its-survived-a-relentless-legal-campaign-against-the-apple-watch-and-it-could-mean-a-key-health-feature-is-returning-to-your-wrist?utm_source=openai))
Implications for Apple Watch Users
With the legal barriers removed, Apple is now authorized to sell redesigned Apple Watch models with the blood oxygen monitoring feature fully enabled in the United States. This restoration is particularly significant for users who rely on this feature for health monitoring purposes. The blood oxygen sensor provides valuable insights into a user’s respiratory and cardiac health, making it a critical component of the Apple Watch’s health and wellness capabilities.

It remains to be seen whether Apple will re-enable the blood oxygen monitoring function on previously sold units through a software update or reserve the feature for future products. Regardless, the resolution of this legal dispute signifies a positive development for both Apple and its customers, ensuring that the Apple Watch continues to offer comprehensive health monitoring features without legal encumbrances.
Conclusion
Apple’s successful navigation through this complex legal challenge underscores the company’s commitment to innovation and its dedication to providing users with advanced health monitoring tools. The reinstatement of the blood oxygen monitoring feature not only enhances the functionality of the Apple Watch but also reinforces Apple’s position in the competitive wearable technology market.
