Apple Watch Series 9 and Ultra 2 Ban: The Latest and What You Need to Know
Apple is resuming sales of the Series 9 and Ultra 2 in the US. Here’s the latest on the patent dispute.

Apple will resume selling the Apple Watch Series 9 and Ultra 2 in the US, at least for now. The company had stopped selling the wearables because of an ongoing legal battle with health tech company Masimo over the blood oxygen detection feature in those watches.
The US International Trade Commission, the federal agency that handles trade-related mandates, previously issued an order that would prohibit Apple from importing the Series 9 and Ultra 2. The decision came after a US judge ruled in January that Apple had infringed on Masimo patents related to the technology used in Apple’s blood oxygen sensing system. The order was under presidential review until Dec. 25 and became final on Dec. 26 after US Trade Representative Katherine Tai decided not to reverse the ITC’s decision.
Apple received a temporary win Wednesday after an Appeals Court paused the ban, allowing Apple to resume selling the devices on Thursday. Apple says that the company expects the US Court of Appeals for the Federal Circuit to hear its motion as early as Jan. 15regarding a stay that would last for the entire duration of the appeal.
Apple is immediately restarting sales of both watches, and both the Series 9 and Ultra 2 watches became available to purchase on Apple’s website Thursday. According to a Wednesday statement, Apple is also working on changes to the Apple Watch Series 9 and Apple Watch Ultra 2 in order to keep the devices on sale.
«Apple strongly disagrees with the ITC’s decision. In addition to the appeal at the US Court of Appeals for the Federal Circuit, Apple is vigorously pursuing legal and technical options to ensure that we can continue to provide consumers with Apple Watch Series 9 and Apple Watch Ultra 2, including having submitted a proposed redesigned Apple Watch Series 9 and Apple Watch Ultra 2 for US Customs approval,» Apple’s statement said.
According to Bloomberg, Apple has been working on software changes to the Apple Watch’s blood oxygen detection feature, and the government is expected to decide on Jan. 12 whether those updates are sufficient.
The Apple Watch is one of Apple’s most important products and has helped make the company’s wearables, home and accessories business its second-largest product category, behind the iPhone. Apple has previously said the size of its wearables unit alone equals that of a Fortune 150 company. Smartwatches were also among the top products sold during the Black Friday period, according to holiday shopping data from Adobe.
Apple began pausing online sales of the affected watches on Dec. 21 and halted in-store sales on Dec. 24. The ITC order specifically applies to sales of the Apple Watch Series 9 and Ultra 2 through Apple in the US. The watches have remained on sale through Best Buy, Amazon, Walmart and Target. The Apple Watch SE, which does not include a blood oxygen detection feature, is not affected.
Apple issued the following statement in response to the initial ITC decision.
«At Apple, we work tirelessly to create products and services that meaningfully impact users’ lives. It’s what drives our teams — Clinical, Design and Engineering — to dedicate years to developing scientifically validated health, fitness and wellness features for Apple Watch, and we are inspired that millions of people around the world have benefited greatly from this product. We strongly disagree with the USITC decision and resulting exclusion order, and are taking all measures to return Apple Watch Series 9 and Apple Watch Ultra 2 to customers in the U.S. as soon as possible.»
Masimo CEO Joe Kiani had said the January decision «should help restore fairness in the market.»
Can I buy the Apple Watch Series 9 and Ultra 2 from other retailers?
The Apple Watch Series 9 and Apple Watch Ultra 2 are both on sale again at retailers in addition to Apple. The ITC order affected US sales of the Apple Watch Series 9 and Ultra 2 through Apple, but 9to5Mac points out that the order prohibited Apple from importing these watches and selling them to resellers, which could limit the watches’ availability should both watches become restricted from sale at a later date.
The order only applied to sales in the US, meaning the Series 9 and Ultra 2 were still available abroad.
Best Buy and Walmart both confirmed that they would continue selling the Apple Watch Series 9 and Ultra 2. Amazon and Target did not respond to CNET’s question about whether the affected watches will continue to be sold, but all four retailers continued offering both watches through their websites.
Which Apple Watch models are affected?
The Apple Watch Series 9 and Apple Watch Ultra 2 are the only models affected. Since the legal dispute involves the blood oxygen sensing tech used in the Apple Watch, the Apple Watch SE continues to be sold as usual. The Apple Watch SE is the lower-end model in Apple’s lineup, meaning it’s missing some health tracking features like blood oxygen sensing and the ability to take an ECG.
Current Apple Watches with blood oxygen monitoring, which includes any non-SE models starting with the Series 6, also remain unaffected. There is no impact for those who already own the Apple Watch Series 9 or Ultra 2.
What is Masimo and why did Apple halt sales?
Masimo is a medical technology company that creates professional and consumer health products, including a smartwatch called the Masimo W1. The ITC order is the latest development in an ongoing legal dispute between Apple and Masimo, in which the latter accused Apple of infringing on its pulse oximeter patents.
What happens next?
Apple said it’s pursuing a range of legal and technical options to permanently resume Apple Watch Series 9 and Ultra 2 sales.
Apple is awaiting the US Court of Appeals for the Federal Circuit to hear the company’s motion for a stay on the temporary lifting of the sales ban, which is expected to take place as early as Jan. 15. Apple is requesting that sales be allowed during the entire duration of the company’s appeal.
Apple is also working on a proposed redesign in an effort to no longer infringe on Masimo’s patents, about which the customs office will review and issue a ruling on Jan. 12, according to Reuters.
Apple didn’t provide details about what the proposed redesign entails. Ahead of the decision being finalized, Bloomberg reported that Apple was developing a software change that alters how the watches monitor and present blood oxygen levels as a workaround.
If I can’t buy an Apple Watch Series 9 or Ultra 2, what are my alternatives?
Those with an iPhone who just want a smartwatch for tracking activity, workouts and sleep should consider the $249 Apple Watch SE. While it lacks ECG and blood oxygen monitoring, it can still provide notifications for high and low heart rates and irregular heart rhythms.
The Apple Watch SE is the best choice for those who are most comfortable in Apple’s ecosystem, but other options work across iPhone and Android, like the Fitbit Versa 4 and Garmin Venu 3.
Those who are specifically looking to monitor blood oxygen levels from home should consider buying a standalone pulse oximeter, said Jennifer Schrack, a professor in the Department of Epidemiology at the Johns Hopkins Bloomberg School of Public Health.
«Consumer wearables are a great supplemental way for people to stay informed about their health, but they are subject to error,» Schrack said over email. «It is important to remember that they are measuring blood oxygen using PPG sensors, which can be affected by things like skin tone.»

Apple, I’m (Sky) Blue About Your iPhone 17 Air Color
Commentary: The rumored new hue of the iPhone 17 Air is more sky blah than sky blue.

I can’t help but feel blue about the latest rumor that Apple’s forthcoming iPhone 17 Air will take flight in a subtle, light-hued color called sky blue.
Sky blue isn’t a new color for Apple. It’s the featured shade of the current M4 MacBook Air, a shimmer of cerulean so subtle as to almost be missed. It’s silver left too close to an aquarium; silver that secretly likes to think it’s blue but doesn’t want everyone else to notice.
Do Apple employees get to go outside and see a real blue sky? It’s actually vivid, you can check for yourself. Perhaps the muted sky blue color reflects a Bay Area late winter/early spring frequent layer of clouds like we typically see here in Seattle.
«Who cares?» you might find yourself saying. «Everyone gets a case anyway.» I hear you and everyone else who’s told me that. But design-focused Apple is as obsessive about colors as they are about making their devices thinner. And I wonder if their heads are in the clouds about which hues adorn their pro products.
Making the case for a caseless color iPhone
I’m more invested in this conversation than most — I’m one of those freaks who doesn’t wrap my phone in a case. I find cases bulky and superfluous, and I like to be able to see Apple’s design work. Also, true story, I’ve broken my iPhone screen only twice: First when it was in a «bumper» that Apple sent free in response to the iPhone 4 you’re-holding-it-wrong Antennagate fiasco, and second when trying to take long exposure starry night photos using what I didn’t realize was a broken tripod mount. My one-week-old iPhone 13 Pro slipped sideways and landed screen-first on a pointy rock. A case wouldn’t have saved it.
My current model is an iPhone 16 Pro in black titanium — which I know seems like avoiding color entirely — but previously I’ve gone for colors like blue titanium and deep purple. I wanted to like deep purple the most but it came across as, in the words of Patrick Holland in his iPhone 14 Pro review, «a drab shade of gray or like Grimace purple,» depending on the light.
Pros can be bold, too
Maybe the issue is too many soft blues. Since the iPhone Pro age began with the iPhone 11 Pro, we’ve seen variations like blue titanium (iPhone 15 Pro), sierra blue (iPhone 13 Pro) and pacific blue (iPhone 12 Pro).
Pacific blue is the boldest of the bunch, if by bold you mean dark enough to discern from silver, but it’s also close enough to that year’s graphite color that seeing blue depends on the surrounding lighting. By comparison, the blue (just «blue») color of the iPhone 12 was unmistakably bright blue.
In fact, the non-Pro lines have embraced vibrant colors. It’s as if Apple is equating «pro» with «sophisticated,» as in «A real pro would never brandish something this garish.» I see this in the camera world all the time: If it’s not all-black, it’s not a «serious» camera.
And yet I know lots of pros who are not sophisticated — proudly so. People choose colors to express themselves, so forcing that idea of professionalism through color feels needlessly restrictive. A bright pink iPhone 16 might make you smile every time you pick it up but then frown because it doesn’t have a telephoto camera.
Color is also important because it can sway a purchase decision. «I would buy a sky blue iPhone yesterday,» my colleague Gael Cooper texted after the first rumor popped online. When each new generation of iPhones arrive, less technically different than the one before, a color you fall in love with can push you into trading in your perfectly-capable model for a new one.
And lest you think Apple should just stick with black and white for its professional phones: Do you mean black, jet black, space black, midnight black, black titanium, graphite or space gray? At least the lighter end of the spectrum has stuck to just white, white titanium and silver over the years.
Apple never got ahead by being beige
I’m sure Apple has reams of studies and customer feedback that support which colors make it to production each year. Like I said, Apple’s designers are obsessive (in a good way). And I must remind myself that a sky blue iPhone 17 Air is a rumored color on a rumored product so all the usual caveats apply.
But we’re talking about Apple here. The scrappy startup that spent more than any other company on business cards at the time because each one included the old six-color Apple logo. The company that not only shaped the first iMac like a tipped-over gumdrop, that not only made the case partially see-through but then made that cover brilliant Bondi blue.
Embrace the iPhone colors, Apple.
If that makes you nervous, don’t worry: Most people will put a case on it anyway.

Astronomers Say There’s an Increased Possibility of Life on This Distant Planet
Using the James Webb Space Telescope, astronomers are working to confirm potential evidence of life on a distant exoplanet dubbed K2-18b.

Astronomers are nearing a statistically significant finding that could confirm the potential signs of life detected on the distant exoplanet K2-18b are no accident.
The team of astronomers, led by the University of Cambridge, used data from the James Webb Space Telescope (which has only been in use since the end of 2021) to detect chemical traces of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), which they say can only be produced by life such as phytoplankton in the sea.
According to the university, «the results are the strongest evidence yet that life may exist on a planet outside our solar system.»
The findings were published this week in the Astrophysical Journal Letters and point to the possibility of an ocean on this planet’s surface, which scientists have been hoping to discover for years. In the abstract for the paper, the team says, «The possibility of hycean worlds, with planet-wide oceans and H2-rich atmospheres, significantly expands and accelerates the search for habitable environments elsewhere.»
Not everyone agrees, however, that what the team found proves there’s life on the exoplanet.
Science writer and OpenMind Magazine founder Corey S. Powell posted about the findings on Bluesky, writing, «The potential discovery of alien life is so enticing that it drags even reputable outlets into running naive or outright misleading stories.» He added, «Here we go again with planet K2-18b.Um….there’s strong evidence of non-biological sources of the molecule DMS.»
K2-18b is 124 light-years away and much larger than Earth (more than eight times our mass), but smaller than Neptune. The search for signs of even basic life on a planet like this increases the chances that there are more planets like Earth that may be inhabitable, with temperatures and atmospheres that could sustain human-like lifeforms. The team behind the paper hopes that more study with the James Webb Space Telescope will help confirm their initial findings.
More research to do on finding life on K2-18b
The exoplanet K2-18b is not the only place where scientists are exploring the possibility of life, and this research is still an early step in the process, said Christopher Glein, a geochemist, planetary researcher and lead scientist at San Antonio’s Southwest Research Institute. Excitement over the significance of the research, he said, should be tempered.
«We need to be careful here,» Glein said. «It appears that there is something in the data that can’t be explained, and DMS/DMDS can provide an explanation. But this detection is stretching the limits of JWST’s capabilities.»
Glein added, «Further work is needed to test whether these molecules are actually present. We also need complementary research assessing the abiotic background on K2-18b and similar planets. That is, the chemistry that can occur in the absence of life in this potentially exotic environment. We might be seeing evidence of some cool chemistry rather than life.»
The TRAPPIST-1 planets, he said, are being researched as potentially habitable, as is LHS 1140b, which he said «is another astrobiologically significant exoplanet, which might be a massive ocean world.»
As for K2-18b, Glein said many more tests need to be performed before there’s consensus on life existing on it.
«Finding evidence of life is like prosecuting a case in the courtroom,» Glein said. «Multiple independent lines of evidence are needed to convince the jury, in this case the worldwide scientific community.» He added, «If this finding holds up, then that’s Step 1.»
