The legal battle between Finnish wearable giant Oura and India's Ultrahuman has reignited in the United States. Following a previous patent infringement victory that forced the removal of the Ultrahuman Ring Air from US shelves, Oura has launched a fresh legal offensive against its competitor.

Oura sues Ultrahuman in the US once again, threating the new Ring Pro

Despite Ultrahuman's attempts to return to the American market with the redesigned Ring Pro, Oura has filed a new lawsuit. This latest action centers on two specific patents concerning internal hardware and overall design. Oura is not only pursuing financial compensation but is also requesting a court injunction to halt all US sales of the Ring Pro.

Because the Ring Pro is produced for the US market at a facility in Plano, Texas, the proceedings are taking place in a Texas federal court. Oura has also named SVTronics, the contract manufacturer responsible for the device's production, as a co-defendant in the litigation.

Ultrahuman has pushed back against the allegations, asserting that the Ring Pro was engineered specifically to resolve the patent conflicts associated with the Ring Air. The company maintains that the new hardware does not infringe upon Oura's intellectual property and notes that the product has already been cleared by US Customs and Border Protection.

Adding a layer of controversy to the timing, one of the patents Oura is leveraging in this suit was granted a mere 48 hours before the legal filing.

While the Ring Pro remains available in the US pending a judicial decision, Ultrahuman continues to sell its product lineup in other global markets without interruption.
