The global market for wearable technology has seen rapid growth over the last decade, and with it has come a surge in patent battles. The latest development involves India’s Ultrahuman and Finland’s Oura Health, two companies known for their innovation in health-tracking smart rings. In August 2025, Ultrahuman filed a patent infringement lawsuit against Oura in the Delhi High Court, adding a new layer to an already heated rivalry. Below, our Ann Arbor, MI patent search lawyer at Patent Baron PLLC provides insight into this issue.
The Background
Oura has long been considered the pioneer in the smart ring space, with its Oura Ring widely recognized for sleep, recovery, and wellness tracking. Ultrahuman, founded in India, has emerged as a competitor with its Ring AIR, designed to combine high-end health monitoring with accessible insights for users. According to reporting by Android Central and the Times of India, Ultrahuman alleges that Oura’s fourth-generation ring borrows from its patented technologies, particularly in areas related to sensor integration, device construction, and the processing of physiological data.
The lawsuit comes only months after Oura secured a significant victory in the United States. In early 2025, the U.S. International Trade Commission ruled that Ultrahuman and another competitor, RingConn, had infringed Oura’s intellectual property. The ruling granted Oura exclusion orders preventing imports of Ultrahuman products into the American market. Coverage from Wearable and Oura’s own statements confirm that the decision was based on claims of U.S. Patent No. 11,868,178, which covers aspects of wearable computing design.
Ultrahuman’s Stand
While the U.S. case dealt a blow to Ultrahuman, the company has responded with its own legal offensive in India. Ultrahuman argues that Oura has encroached on patents granted by the Indian Patent Office, which relate to the integration of multiple sensors within a ring, structural design for durability and comfort, and algorithms that generate insights on sleep and women’s health. Though the specific patent number has not yet been made public, similar filings in Europe and the United States reveal Ultrahuman’s focus on novel methods of combining sensors on a compact circuit board and processing the data in ways optimized for wearable form factors.
Ultrahuman has also framed its case as part of a larger commitment to innovation and accessibility. Unlike Oura, whose business model increasingly emphasizes subscriptions to unlock advanced features, Ultrahuman positions its platform as providing essential health insights without paywalls. This philosophical difference adds a commercial and strategic dimension to the legal dispute, as noted by Android Central.
What It Means For The Industry
The ongoing legal battles highlight both the opportunity and the tension in the wearable market. On one hand, patent enforcement ensures that innovators are rewarded for their research and development. On the other hand, overlapping claims and broad patent filings can lead to years of litigation, creating uncertainty for companies and consumers alike.
For Oura, the Indian lawsuit represents a direct challenge in a major emerging market. For Ultrahuman, it is a chance to assert itself as a global player, capable of defending its intellectual property while advocating for a different model of user accessibility.
As the case unfolds in India, its outcome will help shape not only the future of these two companies but also the competitive landscape of smart rings worldwide. Both sides have already proven their willingness to fight hard, and it is likely that further legal battles will follow in other jurisdictions.
