You’ve probably seen the headlines about the Apple Watch almost getting banned every other month. It's a mess. Most people think it’s just one big legal fight, but it’s actually a bunch of different companies trying to take a bite out of Apple’s wrist-worn empire. While Masimo is the one that actually got the blood-oxygen sensor disabled for a while, the apple watch alivecor itc lawsuit patents saga is a whole different beast. It’s a story about a small innovator, a tech giant, and a legal battle that basically just ended with a whimper in early 2026.
Honestly, it's kinda wild how long this dragged on. AliveCor, a relatively small med-tech company, was actually the first to bring FDA-cleared ECG tech to the Apple Watch through an accessory called the KardiaBand. Then Apple launched the Series 4 with its own ECG, and suddenly, AliveCor was in a fight for its life.
The Patent War That Almost Grounded the Apple Watch
The core of the issue was three specific patents held by AliveCor. These weren't just random ideas; they covered the way a wearable device uses sensors to identify heart arrhythmias like Atrial Fibrillation (Afib). AliveCor felt like Apple invited them in for a "partnership" meeting in 2015, saw the secret sauce, and then just built it themselves.
In 2021, AliveCor went to the International Trade Commission (ITC) to get the Apple Watch banned from being imported into the U.S.
The ITC actually agreed with them! In late 2022, they issued a Limited Exclusion Order. This was a huge deal. It meant that if things went AliveCor's way, Apple wouldn't be able to sell any Apple Watch with ECG tech in the United States. Even President Biden got involved, or rather, his administration chose not to veto the ITC’s decision in early 2023. At that point, it looked like AliveCor was about to win the lottery.
But Apple has better lawyers than almost anyone on the planet.
While the ITC was looking at whether Apple infringed the patents, another group called the Patent Trial and Appeal Board (PTAB) was looking at whether those patents should have even existed in the first place. Apple basically argued, "Hey, these ideas aren't actually new or special."
The PTAB agreed with Apple and invalidated the patents. This created a legal paradox: The ITC said the patents were infringed, but the PTAB said the patents were garbage. Everything stayed on hold for years while the courts tried to untie the knot.

The 2025 and 2026 Rulings: The Final Nail
Fast forward to March 7, 2025. The U.S. Court of Appeals for the Federal Circuit officially upheld the decision to kill AliveCor’s patents. Once the patents were declared invalid, the ITC’s ban became "moot." Basically, you can't be guilty of stealing something that the court says nobody owns.
That was the end of the patent threat. But AliveCor wasn't done yet. They still had an antitrust lawsuit claiming Apple was being a bully by changing its software (watchOS) to break AliveCor’s apps.
Just a few days ago, on January 8, 2026, the Ninth Circuit Court of Appeals handed Apple another win. The court ruled that Apple’s changes to its heart rate algorithm were "lawful product improvements." They basically said Apple doesn't have a legal duty to keep its old, less-efficient tech around just so a competitor's app keeps working.
Why This Actually Matters for You
You might think this is just corporate drama, but it's really about how much control a company has over the "ecosystem" you live in. If you're a developer, this is scary. It means Apple can update its software in a way that makes your product useless, and as long as they can claim it "improves" the user experience, they're legally in the clear.
For us regular users? It means your Apple Watch isn't going anywhere. The threat of an import ban based on the apple watch alivecor itc lawsuit patents is officially dead.
Here is a quick breakdown of where things stand now:

- The Patents: Invalidated. They no longer protect AliveCor, and Apple doesn't owe them anything for the ECG tech.
- The Import Ban: Cancelled. It’s a non-issue now.
- The Antitrust Claim: Dismissed as of January 2026. The courts decided Apple isn't a "monopolist" just for updating its own software.
- The Hardware: Apple is still fighting Masimo over blood oxygen sensors (that's a different mess), but the ECG features are safe.
What You Should Do Now
If you were holding off on buying a watch because of the legal drama, don't worry about the AliveCor side of things anymore. However, keep an eye on the Masimo case if you care about the blood oxygen (SpO2) feature, as that one is still a bit of a moving target with redesigns and ongoing appeals.
If you’re a developer building for the Apple Watch, the "takeaway" is pretty clear: never rely on a specific Apple algorithm staying the same. They can—and will—change the underlying tech, and the courts have just confirmed they have every right to do so.
Check your current Apple Watch model. If you have a Series 4 or newer (excluding the SE), your ECG app is powered by technology that the courts have now definitively ruled as "fair game" for Apple to use. If you use third-party heart apps, make sure they are updated for the latest version of watchOS, as many older "hacks" to get heart data have been blocked by the very software changes that started this whole fight.
