Battle of the Smart Rings: Oura Sues Ultrahuman for Patent Infringement — Again
The smart ring maker wants to ban the Ultrahuman Ring Pro.
Oura, the maker of the Oura Ring, has filed a new lawsuit against Ultrahuman, the producer of the Ultrahuman Ring Pro, alleging patent infringement in the US District Court for the Eastern District of Texas. The legal dispute between the two companies is ongoing. The complaint from Oura seeks financial damages and halts Ultrahuman's sales of its ring.
A key defendant in this lawsuit is the manufacturer of the Ring Pro, SVTronics, based in Texas. This isn't the first legal confrontation between Oura and Ultrahuman; Oura had previously sued Ultrahuman in Texas in 2023 for infringing on its patents, following an ITC complaint against Ultrahuman, RingConn, and Circular. Ten months later, Oura filed another ITC complaint, this time against Samsung's Galaxy Ring, Reebok Smart Ring, Zepp Health's Amazfit Helio Ring, and Nexxbase's Luna Ring.
These legal battles were prompted by Samsung's preemptive lawsuit against Oura in May 2024 to prevent Oura from suing Samsung for patent infringement. As of July 2025, the conflict remains unresolved. In August 2025, the ITC ruled against Ultrahuman and RingConn for patent infringement. In response, Oura, along with RingConn and Circular, reached settlements and entered into patent license agreements.
However, Ultrahuman's Ring Air was banned in the US. Despite this, Ultrahuman continued to develop its Ring Pro, unveiling the device and launching global sales in February while awaiting clearance from US Customs and Border Protection. This clearance was granted the following month. Yet, Oura argued that the initial US Customs clearance didn't cover the two patents in question in its latest lawsuit.
One of these design patents was issued just two days before Oura's filing. Ultrahuman maintains confidence in the Ring Pro and its innovative features. An Ultrahuman spokesperson stated that the company will respond to Oura's new claims through the proper legal channels and will defend their position vigorously. Ultrahuman remains committed to competition and intellectual property disputes within the smart ring technology sector, emphasizing that they do not affect their ambition or pace.
Ultrahuman's stance is supported by an Oura spokesperson, who accused Ultrahuman of copying Oura's innovations and trying to profit from Oura's market leadership. Ultrahuman also plans to vigorously defend its intellectual property rights and investments.
