Smart-ring maker Oura filed a federal lawsuit in Texas against Indian rival Ultrahuman, seeking to block U.S. sales of the startup's Ring Pro device. Oura claims the redesigned ring infringes two of its patents covering internal components and design. The complaint alleges that Ultrahuman’s Ring Pro violates patents for internal parts like batteries, circuit boards, and sensors.
One of those patents was issued to Oura just two days before the lawsuit was filed. Oura is seeking monetary damages and a permanent injunction to stop U.S. sales. Texas-based electronics manufacturer SVTronics was also named as a defendant for allegedly making the rings. Ultrahuman recently returned to the U.S. market after a previous import ban halted sales of its Ring Air device following an International Trade Commission ruling.
An Oura spokesperson stated that Ultrahuman failed to address ongoing patent infringement with its redesigned product. Oura has targeted several other smart-ring competitors with patent claims, including Samsung and RingConn. Meanwhile, the growing smart-ring market is projected to reach 4.9 million shipments this year.
