Smart ring maker Oura has filed a lawsuit against Indian rival Ultrahuman, aiming to block U.S. sales of its Ring Pro. This legal action comes just months after Ultrahuman's redesign allowed it to re-enter the American market following an import ban.
Background of the Dispute
The lawsuit, filed on Thursday in a federal court in Texas, is part of a series of patent disputes Oura has initiated against various smart-ring manufacturers, including Samsung and RingConn. Oura claims that Ultrahuman's Ring Pro infringes on two of its patents related to the ring's design and internal components, such as the battery and sensors.
Oura is seeking both monetary damages and a permanent injunction to prevent Ultrahuman from selling the Ring Pro in the U.S.
Recent Developments
Ultrahuman's redesigned Ring Pro was launched in February and received a favorable ruling from U.S. Customs and Border Protection in March, allowing the startup to return to the U.S. market. This ruling followed an import ban on Ultrahuman's earlier Ring Air, which was imposed after Oura secured a patent infringement ruling from the International Trade Commission in August of the previous year.
An Oura spokesperson stated:
“"Ultrahuman has a history of copying Oura’s innovations, as demonstrated by the 2025 ITC ruling against the company. Ultrahuman introduced a redesigned ring but failed to address continued infringement of Oura’s patents, seeking instead to capitalize on our innovation and the market leadership we have built."
Oura contends that the Customs ruling only addressed the patent involved in the earlier dispute, not the two patents cited in the current lawsuit: D804,471 and 12,769,363. The latter patent was issued to Oura on October 20, just two days before the lawsuit was filed, and covers a smart-ring design that includes internal components like a curved battery, circuit board, magnets, and sensors.
