Mr. Clark, per my last post, did you try again?
Try what? Still no blood ox data since I got the new watch
This is not true. I have an Apple Watch Ultra 2 which was purchased during this ādisputeā, back in June, and itās had the Blood Oxygen app on it from the beginning. No software updates Iāve done have removed it, either.
Yep, on an Apple Watch Ultra 2, since June.
Was the watch purchased directly from Apple? The Apple support document states that the restriction applies to āunits sold BY Apple on or after January 18, 2024 [emphasis added].ā
If you bought it through a third-party such as Amazon or Best Buy, it might have escaped the restriction.
ji, do you have sleep set up? For starters, in the phoneās watch app turn on āTrack Sleep with Apple Watchā. If you get a plot of stages of sleep, then your sensor is working. Sometimes wristband tightness is an issue. If you see the plot and still donāt get ox, let us know.
I canāt see how it would have escaped restrictions, but it WAS purchased refurbished from a third party. And as I mentioned, doing software updates since purchasing have not removed it.
If it was originally sold before Jan 2024, it would have been before the restriction was imposed.
Apple doesnāt remove the functionality after the fact, only at the factory prior to sale.
Presumably Apple could reenable the sensor via a software update if the injunction was canceled, as the hardware still includes the sensor, but the injunction only applies to new devices, not previously sold ones.
Yes, Iāve been tracking sleep for years, and wear the watch all day every day, other than charging for short stints. Still no blood ox measurements.
Ok, step 2. In the phoneās watch app, I have focus set to āMirror my iPhoneā. In my phone I have Focus>Sleep>Apps>Allow Notifications From>Blood Oxygen.
I just saw this Apple press release:

Interesting. I had assumed that theyād settled with Massimo (sp?) but this looks like an end around.
A redesign which is viewed by patent lawyers as independent would do the trick. Many thanks fo David C.
It also occurs to me that Masimo may not agree that itās not infringing.
iOS 18.6.1 has just dropped.
Maybe. According to Appleās press release, it was āenabledā by a ruling of the US customs court, which made the original ruling that Apple could not import watches based on the patent. [edit: that was a ruling by the International Trade Commission, or ITC.]
I havenāt closely read the patent, but it may be that āprocessingā and āshowing the resultā on the companion iPhone rather than on the watch itself was the loophole / end-around that Apple was able to use.

Thinks it was able to use. Appleās been pretty fast and loose with a fair number of patents, so Iām not willing to take their word that this is a legitimate work around.

It was approved by a US Customs ruling (I said court before - I donāt think it was in court reading this again.) So far Masimo has not responded in the press, and Iām sure if they had in the courts we would have heard about that as well. Perhaps they are growing weary of court costs in this case?
iOS 18.6.1 and watchOS 11.6.1 are already out. Youād think that Masimo would have tried to get an injunction to stop these releases if they were planning to appeal this.
11.6.1 is being offered even on watches that already have blood oxygen readings, like my Ultra.
(Perhaps that gold and glass trophy 
helped things along.)
Masimo has responded.
It would be worth understanding that Appleās not a reliable source on these kind of things. Itās a trillion dollar corporation that likes to punch down, as developers have been noting for a while.
Weāll see what the legal system decides.
