    Essential Insights

    1. Trade Ban Appeal: Apple is appealing a trade ban that forced it to remove the blood oxygen sensor from its smartwatches due to a ruling by the International Trade Commission (ITC) favoring health tech startup Masimo in 2023.

    2. Legal Arguments: The U.S. Court of Appeals is reviewing arguments from both Apple and Masimo regarding the original ban, with Apple contending that Masimo’s concurrent smartwatch development shouldn’t justify the trade restriction.

    3. Sales Impact: The ban led Apple to remove the blood oxygen feature in 2024, allowing for the resumption of sales of the Apple Watch Series 9 and Apple Watch Ultra 2 in the U.S. market.

    4. Health Feature Ambitions: While Apple’s blood oxygen sensor was less accurate than clinical devices, its removal highlights the company’s ongoing ambition to enhance health features in future watch models.

    Apple is making another attempt to overturn the trade ban that forced it to remove the blood oxygen sensor from its smartwatches. This move follows a 2023 decision by the International Trade Commission (ITC) that prohibited sales of the Apple Watch due to patent violations by health tech startup Masimo.

    Recently, the U.S. Court of Appeals for the Federal Circuit reviewed arguments from both Apple and Masimo. Apple contends that Masimo’s development of its own smartwatch when Apple launched the Series 6 in 2020 is not a valid reason for the ban. Masimo disagrees, standing firmly by its claim.

    Earlier this year, the appeals court briefly paused the ban, allowing more time for deliberation. However, the ITC ultimately sided with Masimo, prompting Apple to remove the blood oxygen feature in early 2024. This decision enabled the company to resume sales of the Apple Watch Series 9 and Apple Watch Ultra 2.

    The dispute extends beyond the blood oxygen sensor. Interestingly, Masimo’s smartwatches also infringed on Apple’s patents. Yet, Apple’s focus remains on the health-monitoring capabilities provided by the blood oxygen sensor. While not as precise as medical-grade pulse oximeters, it forms part of a broader suite of heart health features.

    Apple aims to reinstate this feature in future devices, possibly enhancing its offerings with more advanced health functionalities. As urban innovation continues, the integration of health technology into wearables like smartwatches represents a significant step forward in personal health management. These advancements could play a key role in the development of smart cities, where technology enhances public health and well-being.
