Oura Sues Ultrahuman Again: What It Means for Ring Pro Buyers

One of the two patents Oura is using against Ultrahuman’s Ring Pro was issued on October 20, two days before Oura filed suit. The new case in federal court in Texas seeks damages and a permanent injunction that could stop US sales of the ring Ultrahuman redesigned to get around Oura’s last win. For smart ring buyers, nothing changes today. The bigger question is whether the US market will have room for an Oura rival that doesn’t take a license.

What Happened

Gadgets & Wearables reports that Oura filed a new complaint in the US District Court for the Eastern District of Texas. Oura’s own statement says the suit follows the 2025 International Trade Commission ruling that Ultrahuman’s ring infringed Oura’s patents, which led to an import ban on the Ring Air.

Ultrahuman answered with the Ring Pro, launched in February with redesigned internals, longer battery life and a new charging case. US Customs and Border Protection cleared it in March, and it returned to the US market. Oura’s argument is that the Customs ruling only addressed the patent from the earlier dispute. The new case asserts two others:

• D804,471: a design patent covering the ornamental design of a wearable computing device.
• 12,769,363: a utility patent, issued October 20, describing a ring with a curved battery, circuit board, charging magnets and optical, temperature and movement sensors.

The complaint also names SVTronics, which it says makes the Ring Pro at a facility in Plano, Texas.

Why It Matters

Both sides are dug in. Oura calls Ultrahuman’s claim that the redesign no longer infringes “false,” and argues that “changing a product to sidestep one patent does not give Ultrahuman the right to use the rest of Oura’s innovations.” Ultrahuman CEO Mohit Kumar told TechCrunch that “there is no court order affecting Ring Pro, and it remains available to customers in the U.S.” Ultrahuman’s statement adds that the newly asserted claims haven’t been decided by a court.

Gadgets & Wearables makes a fair point about timing: a freshly issued patent doesn’t by itself prove infringement. TechCrunch notes that this is the latest in a string of patent disputes Oura has brought against rivals, including Samsung and RingConn. RingConn signed a multi-year licensing deal with Oura that let it keep selling, while Ultrahuman has chosen to fight.

What This Means for Smart Ring Buyers

Ring Pro owners and shoppers aren’t affected by the filing itself. The risk is longer term: if Oura wins a permanent injunction, Ultrahuman could be stopped from selling the Ring Pro in the US. No court has ruled on that yet.

The case also shows how Oura is using its position. Stack Archive covered its IPO filing at a $16 billion valuation. Patent enforcement and licensing are part of how a market leader protects that value, and they shape which rings US buyers can choose from.
