At Oura, innovation is at the heart of all we do. We have spent years investing in researching, designing, and testing the technology that helps people better understand and manage their health. As we do that, we must also protect the innovations that make our products unique. 

Today we filed a new complaint in the U.S. District Court for the Eastern District of Texas against Ultrahuman for patent infringement. This action follows a 2025 ruling by the United States International Trade Commission (ITC) finding that Ultrahuman’s ring infringed Oura’s patents, and barred its smart rings and components from being imported into the United States.

After it was found to be infringing Oura patents, Ultrahuman recently introduced a modified version of its ring, claiming its redesign no longer infringed our patents. That claim is false. Ultrahuman’s latest ring still incorporates many of Oura’s patented innovations and continues to infringe our intellectual property. Oura’s innovations are protected by far more than one patent and the suit we filed today asserts additional patents, including design and utility patents. 

Changing a product to sidestep one patent does not give Ultrahuman the right to use the rest of Oura’s innovations. Patents protect the substance of an innovation, not just its original form.  A redesign that keeps the core intact is still a variation on someone else’s work.

We welcome competition that builds something new and moves the category forward. Protecting our intellectual property is about protecting our ability to keep innovating, as our recent launch of Oura Ring 5, the world’s smallest smart ring and our most accurate yet, shows.

We will vigorously defend our work while staying focused on delivering meaningful new benefits to members. To our community, thank you for your continued trust and support.
