Masimo Wins $634 Million Patent Battle Against Apple Over Apple Watch Blood Oxygen Feature
What Happened?
A federal jury in California has ruled in favor of Masimo in a patent infringement lawsuit against Apple. The jury awarded Masimo $634 million in damages, concluding that apple infringed on a Masimo patent (no. 10,433,776) covering low-power pulse oximeter features used in the Apple Watch’s blood oxygen sensor. While the patent expired in 2022, the verdict covers damages related to 43 million Apple Watch units.
The core of the dispute revolved around the definition of a “patient monitor” as defined within Masimo’s patent.Masimo argued the Apple Watch qualified, while Apple contended it did not.
The central Argument: Defining a “Patient Monitor”
apple maintained that a “patient monitor” necessitates continuous monitoring and the ability to detect critical medical events without fail.They argued the Apple Watch doesn’t meet this standard,as its features aren’t designed for constant,uninterrupted observation.
Masimo countered by highlighting the Apple Watch’s high heart rate notification feature. They presented evidence suggesting this feature possesses 95% sensitivity in detecting elevated heart rates, thereby qualifying the device as a “patient monitor” under the patent’s definition.
Apple attempted to diminish the meaning of the high heart rate feature, pointing out its activation only occurs when the user remains motionless for at least 10 minutes. This, they argued, excludes the Apple Watch from the category of continuous monitoring devices.
Crucially, the case wasn’t directly about the heart rate monitoring feature itself, but rather Masimo strategically used it to establish that the Apple Watch *is* a “patient monitor” – a prerequisite for proving infringement of the blood oxygen sensor patent.
Jury’s Decision and Implications
The jury ultimately sided with Masimo, determining that, for the purposes of the patent in question, the apple Watch *is* considered a patient monitor. This finding directly led to the conclusion that Apple infringed on masimo’s patent related to the blood oxygen sensor technology.
The $634 million in damages represents compensation for the alleged infringement, despite the patent’s expiration. The verdict sets a precedent regarding the interpretation of “patient monitor” in the context of wearable health technology.
