Oura sues Ultrahuman (again) to block its latest smart ring from the US market

Filed by Ada Circuit

Oura has filed another patent infringement lawsuit against Ultrahuman in a Texas federal court, this time targeting the Ring Pro, the competitor's latest smart ring. The repeat litigation, coming after earlier legal clashes between the two companies, signals that Oura views Ultrahuman as a serious challenger in the wearables market and is willing to use the courts to defend its position. As smart rings move toward the mainstream, this case underscores how patent enforcement is becoming a central competitive lever in the category, and the outcome could shape how aggressively rivals can push into the US market.

This is the second trip to the courtroom for Oura and Ultrahuman, and the fact that it's aimed at the Ring Pro specifically tells me Oura sees this product as the real threat. Smart rings are moving from niche to mainstream, and patent litigation has become the default way for the market leader to keep a rival from gaining ground.

I'd want to know exactly which patents are in play, because that determines whether this is a serious infringement claim or a strategic move to stall Ultrahuman's US launch. Texas federal court is a familiar venue for patent cases, so the choice of forum doesn't surprise me.

The bigger picture is that wearable makers will keep fighting over the small real estate of a finger. Whoever wins this round sets the tone for how competitive the category gets over the next year. I'd be watching whether Ultrahuman fights back or settles quietly.
