If Apple's technology is so bad, according to Masimo, then why does Masimo consider Apple a threat?
If Apple stole Masimo's technology, and Apple's technology is unreliable, then by inference Masimo's technology must be unreliable.
If I want a continuous blood O2 monitor I would get Masimo. Except, uh, I can't buy the Masimo watch. Not on their website, not on Amazon. No one knows if Masimo's technology works as no one can buy the watch. Maybe their technology is so bad, in a wearable device, that Masimo is unable to sell the product.
The continuous monitoring must be a significant drain on the battery in a wearable device. Keeping those LEDs lit, and monitoring the response takes power. The battery life on the Masimo product must be measured watching the minute hand rather than the hour hand.
So here is a plan from Masimo. The technology is so unreliable, we won't sell the technology in a wearable device. But we must also stop Apple from selling a wearable device that we have stated is unreliable because we don't want people to know our technology is unreliable.
