Garmin, Apple, Samsung Face Patent Lawsuit Over Fall Detection

The US International Trade Commission has opened a formal investigation into Garmin, Apple, and Samsung over fall detection patent claims filed by UnaliWear. The disputed technology is called RealFall, and it sits at the core of Garmin's Incident Detection feature, which is built into watches like the Forerunner 965, Fenix 7, and Epix series.

Incident Detection on Garmin watches uses accelerometer and gyroscope data to identify sudden impacts or falls during outdoor activities, then sends an automatic alert with GPS coordinates to emergency contacts. It's a feature many trail runners and cyclists rely on for solo training in remote areas. UnaliWear claims this implementation infringes on patents it holds for real-time fall detection algorithms.

Apple's Fall Detection on the Watch Series 9 and Ultra 2 works on a similar principle, using motion sensors to detect hard falls and prompt an emergency SOS call. Samsung's Galaxy Watch line carries comparable functionality. All three companies are now named in the same ITC investigation, which means the commission sees enough merit in UnaliWear's claims to dig deeper.

For athletes, the practical concern is straightforward: an ITC ruling against Garmin could force a software update that weakens or removes Incident Detection entirely, or block imports of affected watch models into the US market. That would hit trail runners and gravel cyclists hardest, since those are the athletes most likely to activate the feature in real conditions.

Verdict: Nothing changes today, and ITC investigations move slowly. But if you're buying a Garmin specifically for safety features on solo long runs or rides, keep watching this case. It could matter.
