- Ultrahuman has sued Oura in India, accusing the Oura Ring 4 of ripping off its patented smart ring tech.
- The dispute centers on sleep tracking, circadian tools, and women’s health features that Ultrahuman says it pioneered.
- Unlike Oura’s subscription-heavy model, Ultrahuman pushes “no paywall” health data and modular add-ons called PowerPlugs.
Update
As word about Ultrahuman’s lawsuit with Oura spreads, the latter has delivered a statement to Android Central about the matter. Oura’s statement is as follows:
“Ultrahuman’s lawsuit in India has no merit and is a blatant attempt to distract from their decisive U.S. defeat. The International Trade Commission ruled unequivocally that Ultrahuman infringed on ŌURA’s intellectual property, blocking all of their smart rings—and components—from the U.S. market through exclusion and cease-and-desist orders. This ruling validates not only the strength of ŌURA’s patents, but also our long-term IP strategy. We’ve now established, at the most rigorous levels of review, that ŌURA’s patents are valid and enforceable—precedent that will shape the future of this category. The facts are clear: ŌURA innovates, Ultrahuman imitates.”

Ultrahuman has filed a patent infringement case against Finnish rival Oura, claiming that the latest Oura Ring copies key features from its own Ultrahuman Ring Air.
The core of the dispute centers on the technology inside Oura’s smart rings. The lawsuit, which was lodged in the Delhi High Court, says the Oura Ring 4 incorporates patented elements of its design, including how sensors, construction, and onboard processing come together to deliver insights on sleep, recovery, and circadian health.
The company argues that Oura has been riding on its innovations, especially in women’s health tracking, glucose monitoring, and non-paywalled data features without permission.
An Ultrahuman spokesperson pointed to Oura’s broader business conduct as part of the reason for taking legal action. The company referenced past media reports that have criticized Oura’s “backroom deals” and described a “pattern of indiscriminate assertion of patent infringement against any and all competitors.”
The spokesperson said the company had “no choice but to defend its innovation,” pointing to previous reports criticizing Oura’s business practices and lawsuits.
Paywall vs. progress: The ideology behind a legal fight
The lawsuit highlights a philosophical split in the wearable market. Ultrahuman has built its brand on offering features without a mandatory subscription, a direct contrast to Oura’s subscription model. The company argues that replicating innovations only to lock them behind a paywall is “anti-innovation and anti-consumer.”
Ultrahuman has been pushing several industry-first features to differentiate itself. This includes the acquisition of viO Healthtech, which led to a smart ring feature for tracking ovulation with over 90% accuracy.
It also offers modular add-ons called PowerPlugs, which let users customize their ring with capabilities like AFib detection or specialized modes for shift workers.
The fight for truly ownable health insights
With this lawsuit, Ultrahuman says it isn’t just defending a specific patent; it’s positioning itself as a defender of open health data and Indian innovation on the global stage.
The case will be one to watch for anyone interested in the increasingly competitive and valuable wearable health market.
