Now Oura Ring faces patent lawsuit from Zepp Health
Zepp Health has filed a patent infringement lawsuit against Oura in Texas, claiming the Oura Ring Gen 3, Gen 4 and the Oura app use technology covered by six of its patents. The case focuses on the software and sensor systems behind activity tracking, sleep analysis and health scoring.
What Zepp Health is accusing Oura of
The lawsuit was filed on April 21st in Texas, in the US District Court for the Eastern District of Texas. It centres on six patents.
These include patent US 8,781,610 for ball game motion recognition, US 8,989,441 for motion recognition data acquisition, US 9,729,693 for determining confidence in wearable sensor measurements, US 10,959,649 for stride length calibration, US 11,806,120 for health risk indicator determination using heart rate and motion data, and US 10,624,575 for sleep monitoring through microactivity states.
Some of these go back to Zepp Health’s earlier sports sensor days, particularly the motion recognition patents. Others are much more relevant to today’s smart rings, especially the ones covering sleep monitoring, signal confidence and health scoring.
That last group is where things get particularly relevant for Oura. Much of the company’s value comes from how it turns raw sensor readings into scores like Readiness, Sleep and recovery insights. If Zepp Health can successfully argue that key parts of that process overlap with its patents, the case becomes much more serious than a background legal dispute.
The counterpunch
There is important context behind this case because Oura has been aggressively defending its smart ring patents. It’s all part of a much bigger legal battle around who controls key technology in the smart ring space.
Last year, the US International Trade Commission opened an investigation after Oura filed a complaint against Zepp Healthh and other companies over alleged patent infringement. Oura argued that rival smart wearable devices were using technology covered by its patents.
This new Texas lawsuit looks very much like Zepp Health pushing back. It is now putting pressure on Oura by arguing that Oura’s own flagship products rely on Zepp-owned technology.
Samsung followed a similar path. Before the Galaxy Ring had even launched, Samsung filed a preemptive lawsuit in the US asking the court to declare that its device did not infringe Oura’s patents. After Oura later responded with an ITC complaint and a separate patent case, Samsung hit back with its own lawsuit in Texas, accusing Oura of infringing Samsung patents related to health tracking features. What started as a defensive move quickly turned into a full two way patent battle.h.
Our takeaway
The smart ring market is clearly no longer a niche category. Once companies like Oura, Samsung and Zepp Health start taking each other to court over patents, it shows these devices have become serious business, not just an interesting side category in wearables.
What stands out here is that both Samsung and Zepp Health appear to be reacting to Oura’s legal strategy rather than starting these fights themselves. Oura has been aggressive in protecting its patent portfolio, and both companies moved after finding themselves in its legal crosshairs.
Some smaller companies have chosen to back down and agree to royalty payments rather than fight through a long legal battle. Samsung and Zepp Health are in a different position. Both have the financial resources to push back.
It will be interesting to see how this plays out, because the outcome could shape not just these companies, but how the entire category evolves over the next few years.
