Oura has sued Indian startup Ultrahuman again, accusing its Ring Pro smart ring of infringing two patents, threatening Ultrahuman's recent U.S. market return after a previous import ban.

Oura, a leading smart ring manufacturer, has initiated another patent infringement lawsuit targeting Indian competitor Ultrahuman and its Ring Pro device. The case, filed in federal court in Texas, alleges that Ultrahuman’s Ring Pro infringes on two of Oura's patents related to the ring’s design and internal components, such as its battery and sensors. Oura seeks monetary damages and a permanent injunction to halt sales of the Ring Pro in the U.S.

Earlier this year, Ultrahuman’s redesigned Ring Pro received clearance from U.S. Customs and Border Protection, enabling the company to return to the American market following a prior import ban on its earlier Ring Air model. That ban resulted from an International Trade Commission ruling in favor of Oura for patent infringement in 2025.

Oura's spokesperson emphasized the company's position that Ultrahuman has a consistent record of copying Oura's innovations, noting that the Customs ruling only applied to a previous patent dispute and did not cover the two patents in the current lawsuit, identified as D804,471 and 12,769,363. Notably, patent 12,769,363 was granted two days before Oura filed this latest lawsuit and covers design elements including a curved battery, circuit board, magnets, and sensors.

The lawsuit also names Texas-based manufacturer SVTronics, which Oura claims produces the Ring Pro under Ultrahuman's direction. Both companies are accused of infringing Oura's patents through manufacturing, importing, and selling the device in the U.S.

In response, Ultrahuman's co-founder and CEO Mohit Kumar expressed confidence in defending against the allegations and stated that the Ring Pro remains available to U.S. customers. He noted the timing of the patents involved, including one issued just before the lawsuit was filed, signaling intention to vigorously contest the claims.

This legal dispute continues an ongoing battle between Oura and Ultrahuman that began in 2023, alongside separate patent enforcement actions Oura has taken against other smart ring makers like Samsung and RingConn. While some competitors have settled with licensing agreements, Oura's aggressive patent enforcement underscores its effort to protect its market position.

Meanwhile, the smart ring market is expanding, with research forecasting shipment growth to 4.9 million units in 2026 and reaching 6.3 million by 2030. Ultrahuman, having recently secured $70 million in funding and explored new applications for its devices with Qualcomm, competes actively in this growing sector. Oura, for its part, has advanced its product features and recently abandoned a planned $2.2 billion IPO, citing market uncertainties.

This latest lawsuit may impact Ultrahuman's trajectory in the U.S. as the two companies continue to contest dominant smart ring technologies across patents and markets.
