Oura Ring Lawsuit: ITC Import Ban, Samsung, and Arbitration

The Oura Ring lawsuit landscape is really several fights at once: a patent enforcement campaign by Oura Health Oy that has already banned Ultrahuman smart rings from the U.S. market, forced rivals like RingConn into licensing deals, and pulled Samsung, Reebok, Zepp Health, and others into active litigation, plus separate suits over advisor stock options and a mass arbitration over user health data.1Forbes. Oura Ring Patent Lawsuit

The Patent Driving Most of the Litigation

Almost every Oura suit points back to one document: U.S. Patent No. 11,868,178, titled “Wearable Computing Device,” issued January 9, 2024. It describes a ring-shaped device with a battery, printed circuit board, one or more sensors, and components sandwiched between an internal and external housing.2ipfray.com.

Oura did not invent it. The patent originated with Motiv, a San Francisco startup, passed to Proxy, Inc. in 2020, and came to Oura when it acquired Proxy in 2023.3htworld.co.uk. Oura Establishing Market Dominance Through IP

Competitors, Ultrahuman loudest among them, argue the patent claims a combination of off-the-shelf parts — curved batteries, flexible circuit boards, optical sensors — that the industry had used for years before its earliest priority date.4Ultrahuman Blog. So What’s the Patent That Oura Is Suing Everyone For The U.S. Patent Trial and Appeal Board took a partial swing at it in a post-grant review (PGR2024-00030).

The ITC Case Against Ultrahuman and RingConn

Oura filed its ITC complaint on March 13, 2024, opening Investigation No. 337-TA-1398 against Ultrahuman entities in India, the UAE, and the UK; Guangdong Jiu Zhi Technology in China; RingConn LLC in Delaware; and Circular SAS in France.9USITC. Certain Smart Wearable Devices, Systems, and Components Thereof

On April 30, 2025, Administrative Law Judge Doris Johnson Hines issued an initial determination siding entirely with Oura, finding every asserted claim of the ‘178 patent valid, enforceable, and infringed by Ultrahuman and RingConn products.10Ouraring. Oura ITC Case

The Falsified Evidence Finding

One finding stood out. To satisfy the ITC’s domestic-industry requirement, Ultrahuman tried to show it operated a manufacturing facility in Plano, Texas. The ALJ determined that Ultrahuman had altered images of a third party’s building to display Ultrahuman signage and had doctored images of manufactured parts to label them as Ultrahuman products. Ultrahuman’s CEO continued testifying about the facility on cross-examination even after Oura’s objections surfaced the tampering, and Ultrahuman’s counsel did not correct him. The ALJ formally declared the CEO a “non-credible witness.”11Fish & Richardson. ITC Round Up Q2 2025

The Import Ban Takes Effect

On August 21, 2025, the full Commission issued its final determination finding a violation of Section 337 of the Tariff Act of 1930, ordering a limited exclusion order and cease-and-desist orders against both Ultrahuman and RingConn.12BusinessWire.

How the Two Companies Responded

RingConn settled. On October 21, 2025, it announced a multi-year patent license agreement with Oura allowing continued U.S. sales of its rings and companion app in exchange for confidential royalty payments.13RingConn. Oura and RingConn Enter Multi-Year Patent Licensing Agreement

Ultrahuman appealed. On October 22, 2025, it filed with the U.S. Court of Appeals for the Federal Circuit (Case No. 26-1083), represented by former U.S. Solicitor General Neal Katyal, and sought an emergency stay of the import ban. Both the ITC and the Federal Circuit denied that stay in December 2025. Ultrahuman’s opening briefs are filed and Oura’s response is due in May 2026; the case is being treated as a companion to Case Nos. 26-1258 and 26-1410.14Justia Dockets. Ultrahuman Healthcare Pvt. Ltd. v. ITC, No. 26-1083

Samsung, Reebok, Zepp, and Nexxbase

Oura widened the campaign after winning at the ITC. On November 17, 2025, it filed patent infringement suits in the U.S. District Court for the Eastern District of Texas against Zepp Health (Amazfit Helio Ring), Reebok International and its licensees, and Nexxbase Marketing (Luna Ring, doing business as Noise). All three suits center on the ‘178 patent, and the Reebok complaint (Case No. 2:25-cv-1129) adds a second patent, U.S. Patent No. 12,353,244, and names Truconnect Ltd. as the actual manufacturer of the Reebok Smart Ring.15ALM. Oura Ring v. Reebok Complaint

Two days later, on November 19, 2025, Oura filed a fresh ITC complaint against Samsung, Reebok, Zepp Health, and Nexxbase. By January 8, 2026, Nexxbase had submitted a Consent Order to the ITC agreeing to stay out of the U.S. market for the life of the asserted patents.7Ouraring. ITC Action Patent Infringement

Samsung’s Counterattack

Samsung tried to get out ahead of this in 2024, preemptively suing Oura to invalidate its patents, but a judge dismissed that case in early 2025 for lack of evidence that Oura’s enforcement was directed at Samsung at the time.8Android Central. Oura Sues Samsung, Amazfit as It Demands Royalty Payments From Remaining Smart Ring Rivals Samsung then brought its own ITC complaint. On January 13, 2026, the ITC opened Investigation No. 337-TA-1478 to examine whether Oura’s rings infringe four Samsung patents covering biosignal measurement, biometric detection, and high-frequency transmission circuits.16Federal Register. Certain Wearable Devices Institution of Investigation

In parallel Eastern District of Texas litigation (Case No. 2:25-cv-01181), Oura filed motions on February 27, 2026, to dismiss Samsung’s patent counterclaims, arguing Samsung’s patents cover abstract ideas and generic computer processes lacking inventive concepts.17Bloomberg Tax.

Ultrahuman’s Counterclaim in India

Ultrahuman opened a second front while the U.S. ban was pending. In August 2025 it sued Oura in the Delhi High Court, asserting Indian Patent No. IN 549915, “Electronic Ring Including Sensors for Monitoring Health and Fitness Parameters,” granted September 10, 2024. The patent covers ring architecture featuring integrated PCB, PPG sensors, temperature and motion sensors, a battery, a wireless charging coil, and the microcontroller processing used to derive metrics like sleep stages and readiness scores.18Times of India. Ultrahuman Takes Oura to Delhi High Court Over Smart Ring Patents

Ultrahuman alleges the Oura Ring 4 copies its sensor integration and onboard processing, and also accuses Oura of imitating its women’s health features, circadian tools, and glucose monitoring platform. Oura called the suit meritless. As of November 2025, the Delhi High Court’s Division Bench reinstated the case after an initial procedural setback, and it remains active.19Ultrahuman Blog.

The Peter Attia and Drew Brees Stock-Option Suits

Two prominent former advisors are suing Oura over equity, separate from any patent question.

Longevity physician Peter Attia filed his complaint in July 2023 (Case No. 4:23-cv-03433, Northern District of California), claiming Oura reneged on a 2017 agreement to grant him 20,000 shares of equity, vesting over three years, in exchange for helping develop, test, and market the ring. Oura’s defense is that its board never authorized the grant and that such approval was required under Finnish law.20Reuters. Epstein Files Upend Lawsuit Over Stock Options by Longevity Expert Peter Attia

After the release of the so-called “Epstein files,” Oura filed counterclaims alleging fraudulent concealment, negligent misrepresentation, and unjust enrichment, arguing that Attia failed to disclose a relationship with Jeffrey Epstein spanning 2015 to 2019 and that Oura would never have engaged him as an advisor or brand ambassador had it known. Oura is seeking to rescind Attia’s stock option agreement, reportedly valued between $25 million and $31 million, along with compensatory and punitive damages.20Reuters. Epstein Files Upend Lawsuit Over Stock Options by Longevity Expert Peter Attia Attia defeated Oura’s motion to compel arbitration, and the Ninth Circuit upheld that ruling in 2025.

A related dispute involves the Brees Company, Inc., an entity associated with former NFL quarterback Drew Brees (Case No. 24-cv-08548). It concerns the “Oura Health OY / Oura Ring Inc. Adviser Equity Plan 2018 US Stock Option Agreement,” with the Brees Company alleging that Oura CEO Harpreet Singh Rai represented the company was receiving a valid options contract for Oura Health stock. In February 2025, a federal judge remanded the case to San Francisco Superior Court after finding the federal court lacked subject matter jurisdiction.22GovInfo. Brees Company, Inc. v. Oura Health Oy, No. 24-cv-08548

Data Privacy: Mass Arbitration, Not a Class Action

Attorneys have been investigating whether Oura illegally shares personal health information — including heart rate, sleep metrics, recovery data, and menstrual cycle tracking — with third-party advertisers without user consent. If you were expecting a class action lawsuit, there isn’t one on that fact pattern. These claims are being pursued through mass arbitration, handled privately, with proceedings potentially lasting 8 to 18 months.23Class Action U. Oura Ring Mass Arbitration

What to Watch in 2026

Three decisions will shape whether Oura’s current dominance holds. The Federal Circuit’s ruling in Ultrahuman’s appeal will decide whether the import ban stands. Samsung’s ITC investigation against Oura, Investigation No. 337-TA-1478, could put Oura on the defensive side of an exclusion order for the first time. And the PTAB appeal on the ‘178 patent’s core claims could weaken or strengthen the document Oura has used to reshape the market. Rulings in several of these cases are expected during 2026.
