Oura Sues Ultrahuman a 2nd Time Over Smart Ring Patents

Oura has filed a second patent lawsuit against Ultrahuman, seeking to block U.S. sales of the Indian startup's redesigned Ring Pro just months after the device returned to American shelves, according to TechCrunch.

The complaint, filed Thursday in federal court in Texas, accuses Ultrahuman of infringing two Oura patents covering the ring's design and internal components, including its battery and sensors, TechCrunch reported. Oura is asking the court for monetary damages and a permanent injunction that would stop further U.S. sales of the device.

What patents does Oura say Ultrahuman infringed?

Oura's filing names two patents: design patent D804,471 and utility patent 12,769,363, per TechCrunch. The second patent is newly issued — the U.S. Patent and Trademark Office granted it to Oura on October 20, two days before the lawsuit was filed. That patent covers a smart ring design built around internal components such as a curved battery, circuit board, magnets and sensors, according to the report.

Oura argues these two patents were not part of the earlier dispute that led to an import ban on Ultrahuman's original Ring Air. "To protect its patent rights, Oura is now forced to file this complaint of patent infringement," the company said in its court filing, as quoted by TechCrunch.

Why was Ultrahuman already banned from the US market once?

Ultrahuman's Ring Air was barred from import after Oura won a patent infringement ruling from the U.S. International Trade Commission in August 2025, TechCrunch reported. Ultrahuman responded by redesigning the product into the Ring Pro, which launched in February 2026. U.S. Customs and Border Protection issued a favorable ruling on the redesign in March, clearing the way for Ultrahuman to resume selling the device in the United States, according to the outlet.

Oura contends that ruling applied only to the single patent at issue in the original ITC case — not the two patents cited in the new Texas lawsuit. "Ultrahuman has a history of copying Oura's innovations, as demonstrated by the 2025 ITC ruling against the company," an Oura spokesperson told TechCrunch. "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."

How is Ultrahuman responding?

Ultrahuman co-founder and CEO Mohit Kumar told TechCrunch the company is confident in the Ring Pro and intends to fight the claims. "Oura has now chosen to assert different patents, including one that issued just two days before this lawsuit was filed," Kumar said. "We will address these claims through the appropriate legal process and will defend our position vigorously. There is no court order affecting" sales, he added, according to the report.

Who else is named in the lawsuit?

Oura also named SVTronics, a Texas-based electronics manufacturer, as a defendant. The complaint alleges SVTronics builds the Ring Pro at a facility in Plano, Texas, under Ultrahuman's direction, and that both companies infringe Oura's patents through the manufacture, importation and sale of the ring in the U.S., TechCrunch reported.

By the numbers

• 2 patents cited in the new lawsuit: design patent D804,471 and utility patent 12,769,363.
• 2 days: the gap between when patent 12,769,363 issued (October 20, 2026) and when Oura filed suit (October 22, 2026).

What to watch

• Whether the Texas federal court grants or denies Oura's request for a preliminary injunction against Ring Pro sales.
• Whether Ultrahuman pursues another redesign, as it did after the 2025 ITC ruling on the Ring Air.
• How U.S. Customs and Border Protection treats any future Ultrahuman ring models given the new infringement claims.
• Whether SVTronics, the Plano, Texas manufacturer named in the suit, faces separate liability or production disruptions.

The dispute is the latest in a series of patent fights Oura has waged against rival ring makers, including Samsung and RingConn, as the Finland-founded company works to defend its position in the fast-growing wearable ring market, TechCrunch reported.
