Apple Reinstates Blood Oxygen Monitoring in U.S. with iOS 18.6.1, Ending Masimo Patent Dispute

We are delighted to announce a significant update for Apple iPhone and Apple Watch users across the United States. With the recent release of iOS 18.6.1 and watchOS 11.6.1, Apple has not only introduced a suite of enhancements but, more importantly, has reinstated the Blood Oxygen Monitoring feature that was previously unavailable to U.S. customers. This momentous return is a direct result of Apple successfully navigating and resolving a protracted patent dispute with medical technology company, Masimo. This development brings back a vital health tracking capability, underscoring Apple’s commitment to providing comprehensive wellness insights to its user base.

The Return of Blood Oxygen Monitoring: A User-Centric Triumph

The absence of Blood Oxygen Monitoring on U.S. models of the Apple Watch Series 9 and Apple Watch Ultra 2 had been a point of concern for many users. This feature, integrated into the advanced health sensors of these devices, allows individuals to track a crucial metric of their respiratory and cardiovascular health directly from their wrist. Its removal, stemming from a legal battle over patent infringement claims brought forth by Masimo, had left a noticeable gap in the otherwise robust health tracking suite offered by Apple. The release of iOS 18.6.1 and watchOS 11.6.1 signifies a pivotal moment, rectifying this situation and restoring full functionality to affected devices within the United States. We believe this move is a testament to Apple’s dedication to its users and its proactive approach to resolving complex legal challenges to ensure continued access to valuable health features.

Understanding the Masimo Patent Dispute and Its Impact

The legal wrangling between Apple and Masimo began with Masimo alleging that Apple infringed on its patents related to blood oxygen sensing technology. Masimo, a pioneer in noninvasive monitoring, claimed that Apple’s Apple Watch models, specifically those incorporating the Blood Oxygen app, utilized technology derived from Masimo’s patented innovations. This dispute led to an import ban being placed on the latest Apple Watch models in the United States, an executive order that significantly impacted sales and availability.

The ITC Ruling and Initial Consequences

The International Trade Commission (ITC) initially ruled in favor of Masimo, finding that certain Apple Watch models indeed infringed on Masimo’s patents. This ruling had far-reaching implications, including the potential for a U.S. import ban on the affected devices. While Apple continued to sell the Apple Watch Series 9 and Apple Watch Ultra 2 in the U.S. for a period, the looming threat of the ban created an atmosphere of uncertainty. The company diligently sought exemptions and legal remedies to mitigate the impact of the ITC decision, exploring various avenues to continue offering its popular smartwatches with full functionality.

Apple’s Strategic Workaround and Regulatory Engagement

In response to the ITC ruling and the import ban, Apple implemented a software-based workaround. This innovative solution involved modifying the Blood Oxygen Monitoring feature to avoid infringing on Masimo’s specific patented technology. The company engaged extensively with regulatory bodies, including the U.S. Customs and Border Protection, to ensure that its modified devices would not be subject to the import ban. The success of this strategy is now evident with the rollout of iOS 18.6.1 and watchOS 11.6.1, which incorporate these crucial software adjustments. This marks a significant victory for Apple in its ability to adapt and overcome complex legal hurdles while maintaining product functionality for its vast user base.

Key Features and Improvements in iOS 18.6.1 and watchOS 11.6.1

While the reinstatement of Blood Oxygen Monitoring is undoubtedly the headline feature of these updates, iOS 18.6.1 and watchOS 11.6.1 also bring a host of other under-the-hood improvements and potential minor enhancements. Apple consistently refines its operating systems to improve performance, security, and user experience. We anticipate these updates may include:
