Zepp Health Sues Oura 2026: What the Smart Ring Patent War Means for Buyers
The smart ring patent war has entered its messiest chapter yet. Zepp Health — parent company of Amazfit — has filed a patent infringement lawsuit against Ourain the US District Court for the Eastern District of Texas, claiming the Oura Ring Gen 3, Gen 4, and the Oura app use technology covered by six of its patents. This is a direct counter-attack after Oura spent the past year aggressively suing nearly every smart ring competitor on the market. Here's what it means for your wallet and your next purchase.
What Happened
Zepp Health sued Oura on April 21 over six patents covering sleep monitoring, activity tracking, and health scoring algorithms.
Buyer Impact
No immediate effect on current Oura products. Long-term, Oura may face licensing costs that could raise prices or alter software features.
Safest Buy
RingConn Gen 2 at $299 has resolved its patent issues and requires no subscription.
What Six Patents Does Zepp Health Claim Oura Infringes?
The lawsuit targets the core technology behind Oura's health tracking features. The six patents cover:
- Sleep monitoring through microactivity states (US 10,624,575) — the method Oura uses to detect sleep stages by analyzing tiny movements during rest
- Health risk indicators using heart rate and motion data (US 11,806,120) — similar to Oura's Readiness Score, which combines heart rate, HRV, and movement patterns
- Stride length calibration (US 10,959,649) — how the ring estimates walking and running distance from sensor data
- Confidence scoring for wearable sensor measurements (US 9,729,693) — the system that determines how reliable a particular health reading is
- Motion recognition data acquisition (US 8,989,441) — fundamental to activity detection and workout tracking
- Ball game motion recognition (US 8,781,610) — a broader motion-sensing patent that applies to various movement types
If even a few of these patents are upheld, Oura could be forced to license the technology, pay damages, or modify its algorithms. The sleep monitoring and health risk indicator patents are the most impactful — they target features that are central to why people buy Oura rings.
Why Is Zepp Health Suing Now?
Context matters. Oura has been the aggressor in the smart ring patent war since 2024:
- 2024–2025: Oura won a US import ban against Ultrahuman and RingConn through the International Trade Commission (ITC)
- November 2025: Oura filed ITC complaints against Samsung, Reebok (smart ring), Zepp Health (Amazfit), and Nexxbase
- April 2026: A federal judge dismissed Samsung's preemptive lawsuit against Oura, strengthening Oura's legal position
Zepp Health's Texas lawsuit is a classic counter-punch. By claiming Oura's own products infringe Zepp's patents, Zepp creates leverage for a cross-licensing deal— essentially saying "drop your ITC case against us, and we'll drop ours." It puts Oura on the defensive for the first time and complicates their position as the patent enforcer of the smart ring industry.
How Does This Affect Each Smart Ring Brand?
Here's where every major smart ring stands in the patent war as of April 2026:
- Oura Ring Gen 4 — now facing a counter-suit, but still fully available and functioning. The lawsuit targets royalties, not an import ban. Currently $349
- Samsung Galaxy Ring — faces an active Oura ITC investigation that could lead to a US import ban. Currently $399. The riskiest buy right now
- RingConn Gen 2 — resolved its Oura dispute by agreeing to pay royalties. Fully available and patent-safe. Currently $299
- Ultrahuman Ring Air — still fighting Oura in the US; availability is limited due to the import ban
What Should Smart Ring Buyers Do Right Now?
Here's our recommendation based on your risk tolerance:
- Lowest risk: Buy the RingConn Gen 2 at $299 — patent disputes resolved, no subscription, strong health tracking
- Best features despite risk: Buy the Oura Ring Gen 4 at $349 — still the best sleep tracker and app experience, and the Zepp lawsuit is extremely unlikely to affect your ring
- Wait if you can: The Oura Ring 5 is coming this summer with upgraded sensors. If you can wait 4–5 months, you'll get better hardware
- Avoid for now: The Samsung Galaxy Ring carries the most patent risk due to the active ITC investigation. Only buy it at deep discount if you're comfortable with the uncertainty
Patent lawsuits rarely result in products disappearing from shelves overnight. The most likely outcome is a cross-licensing deal between Oura and Zepp Health. But if you're the cautious type, RingConn Gen 2 is the smart money pick right now. Compare all smart rings in our smart ring comparison.

Common questions about the Zepp Health vs Oura lawsuit
Quick answers about the lawsuit, which smart rings are affected, and what buyers should do.
Why is Zepp Health suing Oura?
Zepp Health filed a patent infringement lawsuit claiming that the Oura Ring Gen 3, Gen 4, and the Oura app use technology covered by six of its patents. The patents cover sleep monitoring, health risk indicators, stride length calibration, confidence scoring for sensor data, and motion recognition. This appears to be a counter-attack after Oura filed ITC complaints against Zepp Health's Amazfit products.
Will the Zepp Health lawsuit affect my Oura Ring?
Not immediately. Patent lawsuits take months or years to resolve. Your current Oura Ring will continue working normally. In the worst case, Oura could be forced to license Zepp's patents (adding cost) or modify its software algorithms. An import ban on Oura products is theoretically possible but very unlikely given Oura's strong US market presence.
Which smart ring is safest to buy during the patent war?
The RingConn Gen 2 is currently the safest pick — it resolved its Oura dispute by agreeing to pay royalties and is fully available in the US at $299 with no subscription. The Oura Ring Gen 4 at $349 is also safe for now, as the Zepp lawsuit targets future royalties, not product bans. The Samsung Galaxy Ring carries the most risk due to the active ITC investigation.
Could Oura Ring prices go up because of this lawsuit?
It's possible but unlikely in the short term. If Oura is forced to license Zepp Health's patents, those costs could eventually be passed to consumers. However, Oura is more likely to settle or challenge the patents than to raise prices. The upcoming Oura Ring 5 pricing should not be affected by this particular lawsuit.
