Samsung launches new legal attack against Oura over smart rings

Oura was a well established player in the smart ring market by the time Samsung decided to enter the market in 2024 with the Galaxy Ring. Given Oura's history of filing lawsuits to keep competition in check, Samsung preemptively sued Oura in the US to ensure that the Galaxy Ring's launch wouldn't be jeopardized by potential lawsuits over patent infringement filed by Oura.

This allowed the Galaxy Ring's launch to proceed without any issues, but a judge ultimately dismissed Samsung's lawsuit in March 2025, saying that it acted prematurely as there was no evidence that Oura intended to sue Samsung. No satisfied with the result, Samsung has now launched a new legal attack against its biggest competitor in the smart ring segment.

Samsung filed a lawsuit in June 2024 seeking a declaratory judgement that the Galaxy Ring, which hadn't been released at that time, didn't infringe on five Oura patents. The company also pointed to Oura's history of filing patent infringement lawsuits against competitors over “features common to virtually all smart rings,” including basic health tracking features and even batteries.

It also pointed to statements from Oura CEO who had said that the company would monitor the Galaxy Ring and “take action that's appropriate.” Dismissing the case, Judge Araceli Martínez-Olguín, noted that Samsung's lawsuit failed to allege any legal action by Oura against Samsung, and that public statements from the company weren't enough to prove that Oura would sue Samsung.

Samsung isn't happy with the decision. As @ipfray notes on X, the company is now appealing the judgment to the Federal Circuit. It's hasn't amended the original lawsuit but it's appealing the dismissal.

The company evidently feels that a legal threat from Oura exists that could be detrimental to the Galaxy Ring's presence in the market. An appeal would offer it another chance to secure the relief that it had sought in the original case.
