Ultrahuman Faces Oura Patent Suit in Texas Over Ring Pro Design Infringement Claims

Oura has initiated legal proceedings against rival Ultrahuman to prevent the sale of the Ring Pro smart ring in the United States. The Finnish company alleges that the redesigned device violates two of its intellectual property rights, marking the latest escalation in a series of patent disputes within the wearable technology sector.

According to TechCrunch, Oura filed the complaint in a federal court in Texas, seeking monetary damages and a permanent injunction. The suit names both Ultrahuman and SVTronics, a Texas-based electronics manufacturer accused of producing the device under Ultrahuman’s direction. Oura claims these entities infringe its patents through the manufacture, importation, and sale of the ring.

What we know

The lawsuit focuses on two specific patents: D804,471 and 12,769,363. Oura argues that these cover the ring’s design and internal components, including the battery and sensors. Notably, patent 12,769,363 was issued on October 20, just two days before the lawsuit was filed. It covers a smart-ring design incorporating a curved battery, circuit board, magnets, and sensors.

Ultrahuman’s Ring Pro, launched in February, recently regained access to the US market after a favorable ruling from US Customs and Border Protection in March. This decision followed an earlier import ban on the Ring Air, which resulted from an International Trade Commission ruling against Ultrahuman last August. Oura contends that the Customs decision only addressed the previous patent dispute, not the new claims.

An Oura spokesperson stated that Ultrahuman has a history of copying innovations, citing the 2025 ITC ruling as evidence. The company alleged that Ultrahuman failed to address continued infringement despite releasing a redesigned ring. Oura claims the rival is seeking to capitalize on its market leadership and proprietary technology.

Defender's checklist

• Monitor official legal filings for updates on injunctions that may halt product availability.
• Review supply chain contracts to understand liability if a manufacturer is named in litigation.
• Track patent expiration dates and issuance timelines to assess the strength of infringement claims.
• Verify whether previous customs rulings cover all relevant patents or only specific prior disputes.

The background in plain language

Patent disputes in hardware often involve complex technical comparisons. Companies must prove that a competitor’s product uses protected designs or internal mechanisms without permission. Legal teams analyse component placement, such as battery curvature or sensor integration, to determine infringement. Import bans can block specific models, but redesigned products may bypass these restrictions unless new patents are cited. Organisations should understand that a customs clearance for one version does not guarantee immunity from future lawsuits regarding different intellectual property rights.

What to do and how to stay safe: Oura

• Check vendor communications for notices regarding product availability or legal restrictions in your region.
• Review your organisation’s procurement policies to ensure suppliers have clear intellectual property rights.
• Monitor industry news for updates on injunctions that could impact device supply chains.
• Once the vendor provides an update, verify if alternative models are available to maintain operations.
