Apple was in a patent dispute over this feature with Massimo. Their workaround is to calculate blood oxygen on the iPhone, using the sensors from Apple Watch.

The Apple Watch hardware is otherwise the same. The back of the watch shines light of a specific wavelength into your skin and measures the reflected light. Heart rate sensing uses green (525 nm) and infrared (850–940 nm) light; blood oxygen sensing added a red light at 660 nm in 2020.

The iPhone will now calculate the ratio of absorbed red to infrared light, then apply calibration constants from experimental data to estimate blood oxygen saturation.

              That suggests HN is a monoculture of some sort of united front. It is not. Diversity of opinion is best for this community (and all communities).

              And, sorry, what competition was killed off here? I, as the consumer, was never considering Massimo for my blood oxygen measurement needs. I bought an Apple Watch and just want it to be as feature-full as possible. So does Apple.

                    Yea, so if Apple didn’t copy the other company’s work, they’d have been forced to buy devices from or license the other company’s work. So instead of your money for the blood oxygen sensor going to that company, it went to Apple.

                    I bought a cheap pulse oximeter during the pandemic and what I learned is that when I’m feeling light-headed, blood oxygen is low. So I decided that my body’s built-in blood oximeter is probably good enough most of the time.

                    It’s sort of like having your watch tell you whether you slept well or not. Didn’t you already know? If you think you slept well and your watch disagrees, are you going to trust its opinion over your own?

                  • yifanl 4 hours ago

                        And I know this isn't your argument, but that's a VERY narrow market for the purposes of a US inquiry into monopolies. Like, the normal market definition fights are about whether you should be considering "premium smartphones" or "smartphones" as a whole. Or all of the grocery stores in a given region, and whether that should include convenience stores that also sell groceries.

                        I'd be hard pressed to imagine a court really contemplating an argument that a company has a monopoly in a very small slice of a market. It would be like saying that Rolex has a monopoly in luxury sport watches with headquarters in Geneva.

              Yes "very good", until Apple decides to mass-layoff them, because now, owning the valuable core IP and having killed their primary competitor in the field, Apple can do whatever they want and get away with it because those employees have nowhere else to go in the area. 200+ IQ move </slow_clap>.

              How people on HN can support monopolization of markets and killing of competition is beyond me, since in the end it always bites them in the ass (see recent mass layoffs in the industry), yet this lesson seems to be quickly forgotten.

                > How people on HN can support monopolization of markets

                There was one niche (note: still massive) provider of this technology. Now there are two, one of which is mass. Even if that collapses to one mass, that’s objectively better. More competitors and more consumer surplus is not a monopoly condition.

                There is a difference between being reflexively anti-Apple regardless of the circumstances and being pro-monopoly.

                Lamego only stayed at Apple six months. He was very productive. He filed 12 new patents for Apple. But he apparently had disputes with managers. The details aren't entirely clear. But Lamego ended up resigning. After leaving Apple, he founded his own company, True Wearables, which was also successfully sued by Masimo for trade secret theft.

                  • jart 4 hours ago

                    Maybe if Masimo had made Lamego a significant shareholder, he wouldn't have left his "CTO" role to become a mere Apple employee. Masimo is an $8b company. They created a spinoff called Cercacor which Lamego got to be CTO of. My best guess is it wasn't a real startup like we're used to in the Silicon Valley sense. There wasn't any real opportunity for him to gain generational wealth there if he was successful. Apple not only hired him, but thirty other of their employees too, because Apple recognized that their talent was worth more than a licensing deal. That's the issue with these non-valley enterprises. They're very feudal in the sense that the owners treat their engineers and scientists like ordinary workers, expect total loyalty, and pull out their legal guns when they don't get their way. Big tech companies like Apple are more meritocratic and generally offer smart people much better deals. A court later found Lamego hadn't made his moves entirely fairly, but I believe if you look at the big picture, Apple's behavior wasn't predatory, but rather liberatory.

                      It’s mindblowing how big of a gap this is for these non-tech companies. I work for a company that sold to PE. The owners walked away with the vast majority of a 1.5 billion deal.

                      I asked if employees were given anything. “Sure. Some got as much as 50k!” I was told.

                      Using some standard equity math for early engineers, I back of napkined that the 25 year tenure engineers, if they were at big tech, should have gotten low 7 figures. Nope. They got 50k out of 1.5 billion.

                      (No, PE had no say on how that 1.5 billion was divided up for those of you quick to blame PE.)

                • FuriouslyAdrift 5 hours ago

                  Apple is infamous for driving other companies into bankruptcy to acquire their assets. For a single example, see https://en.wikipedia.org/wiki/Exponential_Technology

                  • ggreer 4 hours ago

                    How is that an example of Apple driving a company into bankruptcy to acquire their assets? Judging from the Wikipedia article, it looks like Exponential Technologies made a good PowerPC CPU, but Motorola promised they'd be able to catch up, and it's safer to bet on a big company that you've been doing business with than to rely on a startup for a critical component.

                    Licensed Mac clones were only available for two years (1995-1997), and discontinuing the program drove many other companies out of business, so it's hard to see how the change was a ploy to acquire a single company's assets. It seems more likely that Jobs discontinued licensing because it caused Apple to lose money.

                    And it looks like much of the Exponential Technologies team continued under a different name, then was bought by Apple in 2010 for $121 million.[1]

                    If there are other examples, can you provide one that is more recent and/or more blatant?

                    1. https://www.nytimes.com/2010/04/28/technology/28apple.html

                    • FuriouslyAdrift 3 hours ago

                      When they started, they were producing for multiple small customers. Apple was frustrated with Motorola and approached them but demanded they massively increase their production capacity (Apple's model for dominating a supplier... put them in debt and beholden to them for orders) and effectively dominated them as a customer...

                      Then used them to negotiate a better price with Motorola, dumped their purchase contract for 'reasons' and bankrupted the company.

                      Exponential sued.. and won $500 million... for breach contract but were destroyed by that point. Apple gobbled up their IP for around $20 mil later on.

                      • ggreer 3 hours ago

                        I can't find any articles about Exponential winning the lawsuit, only that they filed one and sought $500 million in damages. Had they won, I think it would have been in the press. The only thing I could find was Apple's 10K from 1999[1], which says they settled the lawsuit for an undisclosed amount:

                        > This matter was settled during the fourth quarter of 1999 for an amount not material to the Company's financial position or results of operations.

                        If Apple did pay $500 million, I think that would have been material to the company's financial position, as their profit that year was $601M.

                        Again, are there any examples that are less debatable and/or more recent? I don't have a dog in this fight. But if Apple is infamous for this behavior, it seems like there would be stronger examples.

                        Oh... and I forgot this case also exposed that Apple had embedded proprietary IP into the CPU design which made it impossible to seel the already produced CPUs to anyone else (PowerPC chips were in very high demand at the time and these were the fastest on the market).

                  They've also destroyed financial independence. They've engaged in anti-competitive and anti-poaching practices before. There's several famous examples.

                  Anyways, are you saying it's Apple's goal to lift employees in this way, or does it just happen to be incidental to whatever their CEO wants at the moment?

                  Also all the people actually _making_ those devices, surely the largest labor pool supporting their business, have zero financial independence. That's the typical western blind spot.

                  > from employers than any other business in history

                  I think that'd be the US Government and it's GI Bill. Okay, technically not a business, but if the virtue is independence, then it shouldn't matter who provided it.

                  So if Apple came to your company, promising licensing, collaboration and other things, when all along their intention was to "take" "your" employees, you'd be cool with that deception?

                  The employees made out better - good for them. That's a lot easier to do when you have a market cap 400 times higher than that of the company you made all these promises to, and then left holding the bag.

It was clear in the trial that Apple had zero intention of collaboration, licensing, or patent sharing and just used that as a pretense to "get in the room" and see who showed up on Masimo's side so they knew who to target with competing offers.

              Profit distribution only makes sense to owners of the company.

              A better way to give employees a share of the profits is to give them shares of the company. But then that also comes at the expense of compensation in dollars. You cannot pay for groceries with company shares.

              People really like the idea of "When you win, I get money, when you lose, you lose money". Explained like that they agree it's bad, but explained like "Companies should be distributing profits to workers" they fall over themselves about how good of an idea it is.

              Running a business is a gamble and like gambling, you need to put skin in the game to get a share of winnings (and lose your skin in the losses). People are just hyper-focused on the winners.

                Yes, this is capitalism. Apple get 1st rate engineers, Massimo gets 3rd. If they want 2nd, they pay more

              I mean, this doesn't tell us whether they can pay them twice as much or $5 more per year. Some companies make no profit, or very little, or very little per employee.

          • runako 6 hours ago

            Masimo was worth ~$16B when this was going down. They are worth $8B today. This is roughly the size of American Airlines. Masimo is not the biggest company, but they are a large publicly-traded company.

            The company does $2B in revenue and spends close to $800 million annually in sales, general and admin. This is over 3x their R&D budget. (For reference, Apple's R&D spend is higher than its SG&A spend.)

            Per levels.fyi, Masimo is paying senior SDEs in HCOL $150k. They could 10x the comp to these critical employees without it being more than a rounding error in their numbers. (I don't think they would have had to go to 10x. Most people would practically tattoo a brand on themselves for a one-time bonus of $1m.)

            Long story short: Masimo does indeed have the money to compete on salary with Apple for this set of employees. They chose to spend the money on attorneys instead.

            Some companies don't value engineers. That often works, until they end up in an engineering competition against companies that do value engineers.

            • eitally 5 hours ago

              I disagree with your assertion that Masimo has the money to compete. Apple's upside to employing these folks to build the tech into the Apple Watch is FAR, FAR greater than Masimo's potential sales growth for existing pulse ox devices (or patent licenses). With Apple Watches being licensed as medical devices for ECG & pulse ox, this gives clinicians even more reason to leverage them with patients for convenient 24/7 home monitoring. It's not the same market Masimo is serving, at all.

              • runako 4 hours ago

                I specifically did not address any of the corporate competitive dynamics, although it is worth noting that this is more of an existential issue for Masimo than Apple.

                My core point is is that Masimo has far more than enough money to pay strategic employees enough money to keep them. Again, I doubt they would have to go as high as $5m/year for each of the relevant engineers. Masimo could spend that without making a major dent in their finances.

                Could Apple up the ante and make offers of $5B/yr to each engineer? Sure, but we are likely talking about the difference between Masimo offering $150k and Apple offering $500k. These are numbers any public company can afford.

                  This product WAS generally marketed to the healthcare field, not to people directly.

                  I say "was" because it was possible to buy it as a consumer, but there's still no direct competition, as:

                  "Please note that all Masimo consumer products have been discontinued. These include:

              Im not saying they pay them well or not. Theres just not a comparison on comp they could do. That you don't understand the power dynamics between that is something you will hopefully learn about the world as you become more experienced. Apple would just offer more at the end of the day.

              • runako 4 hours ago

                I understand, and this is timely in the context of Meta making $100m offers. I have no data on this, but I would be highly surprised if Apple offered anybody more than $5m/year. Masimo has that much money.

                Could Apple go higher? Sure, but again most people who like their jobs are not going to leave once their needs are met.

                From a competitive standpoint: Masimo has lost $8B in market cap during this kerfuffle. It's entirely possible it would have been rational for Masimo to pay these employees higher than Apple possibly would go in order to not lose those billions in value.

        • alistairSH 4 hours ago

          Two things can be bad at once.

          Apple has a massive war chest they can leverage to crush competition in several ways. As a nation and as consumers, we should at least be wary of what they're doing and whether it stifles competition or innovation. Even if the actions are legal.

          There's a difference between Apple paying more for engineers in general vs Apple specifically targeting a competitor, acquiring all the talent from that competitor, then using the IP that talent brought to roll out substantially the same product.

          • scarface_74 3 hours ago

            There was no IP to poach. The IP was in a publicly available patent.

            Every company that proactively reaches out to an employed individual is doing so because that employee has demonstrated elsewhere and probably at their current job skills and experience that they find valuable and I assume is willing to make a better offer for them.

            Other posters said that Masimo was paying developers $140K - $180k. That’s a nothingburger for good developers. The BigTech company I was working for two years ago was offering returning interns about that much in cash + liquid RSUs

            I once worked for a startup where everyone loved the CTO, the startup got acquired after I left by a PE company.

            When he left to be the CTO of another company in the same vertical, 10 of the employees followed him within the next six months basically taking all of the developers and sales that he wanted and all of the worthwhile staff from the startup. I assume it was for more money.

            If I had still been at the startup when he left, he would have easily “poached” me too?

            Should that also have been illegal? Was that unethical?

        • Teever 6 hours ago

          Apple is able to do what they do now because of the shit they got away with in the Jobs era.

          Because they hobbled competitors and innovation then they're able to do it now.

          It's really hard to determine how detrimental their actions have been to the job market for software engineers.

          It is entirely possible that every software engineer is worse off because Apple severely distorted the market and prevented many competitors from growing to be competitors to Apple and what ever offer Apple made to these people pales to what they could be making if Jobs hadn't done what he did.

          • JustExAWS 6 hours ago

            You mean they hobbled poor little competitors like Google, Adobe, and the other tech companies that agreed to it? Apple was actually one of the smaller companies at the time.

            How is all Apple’s fault? And are you really saying that the iPhone wouldn’t have happened if Apple hadn’t gotten into these agreements?

            In your alternate universe would Nokia or Rim (who wasn’t involved in the agreement) still been relevant?

            • Teever 2 hours ago

              No, they hobbled the competitors that their staff could have formed if they had made more money to do so.

              That collusion between these big companies to deny their employees a wage driven by free markets allowed those companies to accrue wealth and prevent competition from forming.

              That's terrible for their employees, that's terrible for the consumer.

              • scarface_74 2 hours ago

                How did their collusion stop a new company from offering more money than the depressed wages that the collusion was causing?

                Alternatively, if hypothetically without the collusion do you think the upper wage pressure would I have materially affected those companies bottom lines to not create the products that made them profitable?

                • Teever 2 hours ago

                  The hypothetical new companies that I'm talking about would have been formed by their former employees who could afford to do so with the increased money that they would have made if it hadn't been for the criminal collusion to deny them that capital and us as a society a freer market.

                  And you're right, there's a distinct possibility the savings that they made in breaking the law could have affected their bottom line at the time in a way that prevented them from making certain products, but it could have also fostered creativity and innovation in the companies that colluded, and increased competition between them and the new companies that would have formed in a way that would have benefited innovation.

                  What's important is that companies don't break the law and that people are paid as much as they're worth so that they can in turn stimulate the economy in ways that they see fit.

                  • scarface_74 2 hours ago

                    So let me get this straight, if there wages would have been 30% more hypothetically they could have invested their own money (which few startup founders do) built phones or search engines that competed with Apple and Google? Something well funded companies like Microsoft and Facebook couldn’t do?

                    But now are you also saying that Apple did the right thing when they paid Masimo’s employees more so now they can stimulate the economy and in the future start companies?

                    • Teever an hour ago

                      A charitable interpretation of what I have wrote is that if Apple had followed the law then they would have more competition and the market would be a healthier place that benefits software developers and consumers alike.

                      Apple broke the law because they felt that it was in their best interest to the detriment of others and they will likely continue to do so if they feel it is in their best interest.

                        But since when have people making BigTech money been afraid to venture out on their own to found a startup and would 30% more (completely made up number) and that was probably tied up in RSUs and not cash really made a difference?

                        Shouldn’t the idea that these people were making less than market wages spur them to go to other companies besides those seven or venture off on their own?

      IMHO, the problem is that if you are wealthy enough then you don't need to worry about patents. I also think these patents are, on the whole, not great. But here the one company legally got the patent and the another, richer company hired away their talent and paid them to find a workaround to avoid licensing. Smaller companies will continue to license the patent.

      Few tears will be shed for Massimo (or Qualcomm) but the next victim could be a much smaller company, maybe one that would be more of a competitor. I don't like the current patent regime but I do believe enforcement should apply to everyone, not just players who lack the money to rig the game.

In my experience, the Apple Watch blood oxygen monitoring was horribly inaccurate. It would report wildly variable results, often telling me that I had a blood oxygen level of 80% (which, if true, would indicate that I should be getting myself to an emergency room ASAP).

Regular pulse oxygen meters are cheap and reliable.

    On their best days, they're accurate to within 2-4%. But so many things can trip up the reading, like melanin:

      The problem with consumer health sensors is they have both high random error and inconsistent systematic error.

    That caused me nightmares when I was first diagnosed with sleep apnea. I would check my oxygen levels during the sleep to see if my treatment is effective. Even though the CPAP machine would show a few short events Apple Watch would show levels as low as 75%.

    For anyone remotely healthy, 100% of the time your real value will be between 95% and 99%, and there is almost no diagnostic value to it. Heart rate is actually interesting and is something you can learn from and work towards. SpO2 is just "eh...neat".

Like the other comment noted something about family having pneumonia, and I cannot understand how the watch would have made their situation better. If someone in that state wasn't already seeking medical advice, it's hugely unlikely a watch saying "yo it's bad bro" is going to help.

        It's like heralding a G-sensor in your watch telling you that you're falling. It's likely pretty obvious already.

Cause they don't usually think to, but sometimes it lingers and by the time they decide to go into an office, the numbers are pretty low.

It's very uncomfortable and you'll get visual snow but I'm not dead, super or otherwise. Use your hand to clamp over your mouth and shut your nostrils if you want to try.

      That's definitely a danger zone for healthy people but interestingly enough people with things like COPD may have a blood oxygen level in the 80s and while that is indicative of the disease, they may be totally stable and may not even need oxygen [1].

        Bodies are generally pretty amazing in that sense. As long as things go out of spec _slowly_, we will often adapt quite well. In the short term, we will tend to balance even fairly extreme changes out through various chemical processes and in the long term people can even develop heritable genetic changes. (E.g., how people acclimatize and have in some cases adapted to living at higher altitudes[0])

        My grandmother's heart was completely fucked, so they'd have to adjust the alarms on the hospital monitors after checking their files when she went in. It's like "OK, well that's the problem... consults notes... Nope, apparently that is normal for her, now lets figure out what's actually wrong". It wasn't keeping regular time and it would sometimes skip, but apparently it was pumping well enough to keep her alive for several years.

        Normal in humans is definitely relative and medicine has tended to assume that if we average 1000 humans (in too many cases, 1000 white college age men) that's what human normal is, which is crazy even beyond obvious problems like " people normally have 1.999 legs apparently".

I never really understood why protecting Massimo in this situation was more important than allowing customers to access a feature in their watch. I get patent law is important, but they seemed more interested in rent-seeking from Apple than actually providing a desirable product that people could benefit from.

  • crazygringo 3 hours ago

    Patents are literally for rent-seeking.

    They are explicitly not to maximize the number of people who can benefit from a product in the short term, but precisely to limit it so the inventor can make more money.

    The idea being that in the long run the inventions it incentivizes outweigh the people who are limited from benefiting in the short term.

    Judges aren't in the position to weigh societal benefits in each individual patent case. Your framing implies that cost-benefit tradeoff. But that's not how it works. The only question is whether a product infringes or not.

  • ahmeneeroe-v2 4 hours ago

    "Rent seeking" is original intent of patents, correct? The theory being that this incentivizes invention.

    Wasn't patent law since decision wasn't decide in court. ITC banned it from imports. I don't understand how a government entity can wield so much power to block sales of product without using the court system. This should have been litigated.

  • bigyabai 4 hours ago

    Because Apple consciously violated the patent? When you think about it, Apple is lucky the judge didn't demand a hardware recall. They got off pretty easy, and if Apple wanted to be petty, then they could enable the hardware as an API only, and let users do the rest.

    Here in America this is part of our culture: your health gimmeck features are precisely meaningless to the court if the prosecution can prove wreckless harm on Apple's behalf.

Just offloading the analysis to the phone is extremely funny. It also seems like a pretty obvious solution, so I wonder if it was delayed by legal analysis and they only just decided it was likely to hold up in court.

I have it on my garmin and it seems pretty useless. My oxygen level while I sleep has more to do with how tightly I'm wearing it that night than anything else. It also drain the battery fast so I just disabled it.

        To be clear, the research has been going on for a while.

        But extracting an accurate enough signal from noise through the skin is an incredibly complex signal analysis problem. And there are multiple approaches.

        Nothing has FDA approval yet because it's a major question whether any technology developed thus far is accurate enough. I understand there's at least one clinical trial going on right now. Fingers crossed...

          > They're all on a subscription model, you're spending who-knows-how-much per year on a new sensor every few days/weeks.

          Which - to be clear - is because the sensor chemically degrades over time. It's not just rent-seeking; they genuinely don't know how to make one that'll last longer.

Did the Watch Series 9+ incorporate a new sensor or different algorithm? I have an older model that has always had blood oxygen (and it was never disabled, as it was for the 9+).

    Apple only disabled the pulse ox sensor on watches they sold, distributed, or replaced after the ruling. I don't think Apple disabled a working pulse ox sensor on anyone's watch other than repairs.

  • anonu 6 hours ago

    https://rulings.cbp.gov/ruling/H335304 maybe this - from January 2025

    It appears the patent is for "User-Worn Device for Noninvasively Measuring a Physiological Parameter of a User". So Apple is simply moving the logic to a non user-worn device - like a phone - to get around the problem. (this is my quick read / conjecture)

    Here is the original patent https://patents.google.com/patent/US10912502B2/en

    • freehorse 5 hours ago

      Yeah, prob because one cannot patent an algorithm itself, but only a specific implementation. The patent was about a wearable device so i guess the workaround was to do the computations in a non-wearable device.

Massimo invented this technology (yay Massimo!) in the 90s yet their Japanese patents [1] weren't considered prior art (WTF?) because of technical legal reasons.

[1] https://patents.google.com/patent/JP2002542493A5/en%EF%BF%BC

So I suppose if Massimo is going to use a technical legality to extend then Apple can use a technical legality to avoid.

  • parsimo2010 6 hours ago

    Masimo only refined pulse oximetry in the 90s, as pulse oximetry was invented in the 1970s (prior oximeters did not resemble the devices seen today). Everything after that has been tweaks/improvements to the base method, but I wouldn't call them the inventors of the technology.

    The only IP that companies can own now are specific methods/improvements, not the base idea of measuring SpO2 with light. All Apple has to do is avoid the specific improvements that Masimo owns and they are fine.

    https://en.wikipedia.org/wiki/Pulse_oximetry#History

    • bookofjoe 3 hours ago

      Yes. I recall the brand new pulse oximeters (I don't recall the manufacturer) that appeared in the ORs at UCLA Medical Center right around when I started my anesthesiology residency in 1977. They were SUPER expensive when they first came out, so much so that our department bought 3 of them, which were used only for the most critical cases. I remember the chief resident sometimes had to decide who got one when 2 residents/attendings each said their patient was more unstable/critical and thus needed it more.

      These were NOT small devices like the inexpensive fingertip versions you can buy now over the counter; rather, they were big boxlike machines, perhaps 2 feet x 1.5 feet x 8 inches high. They were SO heavy (I'd estimate 25 pounds) they were attached to a stainless steel rolling cart.

  • 7thpower 6 hours ago

andrewmcwatters 6 hours ago

You can buy a fingertip pulse oximeter for like $10. I understand the benefits of having all of these biometric readers directly on your personal device, but the perceived stress over getting this back into the watch seems... I don't know, not wise? In poor taste? Something, but I can't articulate it well.

I mean, we don't have IR blasters on any of our personal devices anymore, and arguably it would be nice to be able to control my TV with my phone like I could with my Palm Pilot forever ago, but that's not in vogue anymore.

I live in a rural area. My old fashioned doctor said to test oxygen levels, all you need to do is pinch your index finger nail down until it goes white. Then when you let go, if it goes back to pink right away, you're good. If it takes more than a few seconds, you're not good.
