Did Apple resolve the patent issue that disabled oxygen saturation in the Series 9? Although it's possible that Sleep Apnea detection uses the oxygen saturatio

  It wouldn't surprise me if they did the latter. The oxygen saturation sensor is fundamentally just another optical sensor with a different wavelength of light -- so if you feed all three wavelengths, plus the accelerometer, into a neural network, you may be able to pick up on oxygen-related physiological signals without explicitly processing an oxygen timeseries.

  No. I was very curious to see if it might be a last minute thing where it came back but the pages for the series 10 clearly don’t list it and if you use the comparison tool it’s highlighted as gone. I hope it’s just still disabled. It would suck for someone to buy a new watch, the fix the dispute in 2 months, and you never get the feature until you buy another new watch. They’re clearly not bending. I don’t know if they’ve given up or waiting on an appeal or maybe home a new administration will tell the ITC to go away or what.

    Non-US watch series 10 specification pages mention it still, so it's there and just disabled. I wonder though if they could legally enable it after the fact on watches imported while the ban was in effect

  They're still appealing, but the underlying patent expires in 2028, so maybe they'll wait it out.
