Apple Loses Lawsuit, Ordered to Pay $634 Million Over Apple Watch SpO2 Feature

Major Patent Infringement Verdict

• 💸 Apple has been ordered to pay $634 million to Masimo for patent infringement related to the SpO2 and health monitoring features on the Apple Watch.
• ⚖️ The jury concluded that Apple utilized techniques covered by Masimo's patents, though the awarded compensation was less than Masimo's initial request of $749 million.
• 🍎 Apple plans to appeal the verdict, asserting that the ruling "runs counter to the facts."

Core of the Legal Dispute

• 🔍 A central question in the lawsuit was whether the Apple Watch qualifies as a patient monitoring device, which would imply direct exploitation of Masimo's patented technologies.
• 🎯 Masimo presented evidence, including the Apple Watch's 95% accuracy in detecting resting heart rate and Apple's own internal description of the device as the "world's most widely used heart rate monitor."
• 🚫 Apple argued that its heart rate alert feature, which activates only after approximately ten minutes of user inactivity, was not equivalent to a medical device.

History of the Conflict

• 🗓️ The conflict between Apple and Masimo escalated in 2020 with the introduction of the Apple Watch Series 6, which included SpO2 sensors.
• 💡 Masimo's CEO, Joe Kiani, developed a signal processing solution for oxygen measurement in 1987, founding Masimo in 1989 and securing key patents for SpO2 accuracy even with patient movement.
• 🤝 After unsuccessful negotiations in 2013, Apple subsequently recruited Masimo executives and engineers, leading to suspicions that Apple intentionally acquired core technologies.

Previous ITC Rulings and Apple's Response

• 🏛️ Between 2020 and 2021, Masimo filed multiple lawsuits against Apple at the International Trade Commission (ITC), resulting in a finding that Apple infringed two patents and a subsequent ban on certain Apple Watch models in the U.S.
• ⌚ In January 2024, Apple was compelled to disable the SpO2 feature on its Watch Series 9, Series 10, and Ultra 2 in the U.S. due to import bans.
• 🛠️ To circumvent legal barriers, Apple developed a new technical solution: the watch now only collects raw data, with the iPhone performing analysis and displaying results in the Health app, a mechanism also integrated into the later Series 11 Watch.

Ongoing Implications

• 🔄 The ITC is scheduled to hold hearings to assess whether Apple's modified oxygen measurement method continues to infringe Masimo's patents.
• 💰 This lawsuit is considered one of the largest penalties in California involving consumer tech products and represents a significant intellectual property dispute.
• 🌱 The outcome directly impacts Apple's strategic focus on health devices, a sector that has been a priority for the company over the past decade.
