The next Apple Watch ban? New lawsuit targets the ‘fall detection’ tech in your favorite smartwatches

• Tech firm UnaliWear is suing Apple, Google, Garmin and Samsung
• At issue is the use of fall detection tech on some of the best smartwatches
• If UnaliWear wins, there could be huge ramifications for the industry

Fall detection is a key feature of many of the best smartwatches, including the Apple Watch and models from Garmin, Samsung and Google’s Fitbit. Yet its future on your device might be in jeopardy, as one company claims that all these devices have illegally copied its technology relating to trips and falls. If it prevails, the smartwatch industry could look very different.

At issue is the aforementioned fall detection tech, which wearables company UnaliWear says infringes on its patents. UnaliWear makes wearables for older adults, with these products featuring a fall detection system called RealFall that it says can distinguish between actual falls and everyday movement.

It’s that ability to differentiate real falls from false alerts that is at the core of the dispute. UnaliWear says that the wearables it has taken issue with – those from Apple, Google, Garmin and Samsung – have infringed upon its patents in order to solve a specific problem.

Right now, the case is being investigated by the US International Trade Commission, with responses expected from the affected companies by roughly the end of January. The case is expected to take over a year to complete, but it could have massive ramifications once it concludes.

For one thing, if UnaliWear is successful, it might request a limited exclusion order. This would block the import of affected smartwatches into the US, leaving the likes of Apple and Garmin unable to ship some of the most popular smartwatches to US customers. As well as that, UnaliWear has filed cases in several US district courts – if it prevails there, it could lead to massive financial penalties being handed out.

How likely is a ban?

Ultimately, it's unlikely that we'll see the likes of the Apple Watch or the Samsung Galaxy Watch banned from import into the US.

One more likely option is that the big-name players might have to license their fall detection technology from UnaliWear. Or they could create a workaround or alternative solution that does not infringe on UnaliWear’s patents, as Apple did when its blood oxygen sensor was ruled to have overstepped on patents held by medical tech firm Masimo.

Speaking of which, the Masimo case demonstrates that this is not the first time that Apple has been sued by a smaller company over the tech it uses in its Apple Watch. In the Masimo case, certain models of the Apple Watch were restricted from import into the US, which meant Apple had to disable the feature for US customers – a significant headache for the Cupertino company.

No doubt Apple – and Samsung, Google and Garmin – will want to avoid anything as drastic this time around. If you’re interested in any of these smartwatches and want to know whether you’ll still be able to buy one in the future, keep an eye on this case.
