Oura Re-Ignites US Patent Battle with Ultrahuman Over Smart Ring Design

The ongoing legal dispute between wearable tech giants Oura and Ultrahuman has intensified, with Oura launching a fresh lawsuit against Ultrahuman in the United States. This renewed legal action specifically targets Ultrahuman's latest smart ring offering, the Ring Pro, signaling a determined effort by Oura to protect its intellectual property in the lucrative US market.

Last year, Oura, a company renowned for its advanced smart rings, successfully pursued a patent infringement case against Ultrahuman in the US. This resulted in the previous Ultrahuman Ring Air being withdrawn from the market after a court ruled in Oura's favor.

Undeterred, Ultrahuman has since redesigned its product and introduced the Ring Pro to the US market. However, Oura has responded swiftly, filing a new lawsuit that alleges infringement of two additional patents. These patents reportedly cover critical aspects of the smart ring's design and its internal components. Oura is seeking substantial monetary damages and is once again requesting a court injunction to halt all sales of the Ring Pro within the United States.

The legal proceedings are currently underway in the federal Texas court. This location is significant as Ultrahuman manufactures its Ring Pro for the US market in Plano, Texas. The contractor involved in this manufacturing process, SVTronics, has also been named as a defendant in Oura's lawsuit.

Interestingly, Ultrahuman maintains that the redesigned Ring Pro specifically addresses the concerns Oura raised regarding the previous Ring Air. The company asserts that the new Ring Pro has already secured approval from the US Customs and Border Protection and confidently states that it does not infringe upon Oura's existing patents.

However, a notable detail in the lawsuit is that one of the patents Oura is citing was reportedly issued a mere two days prior to the filing of the current legal complaint.

For the time being, Ultrahuman's products remain available for purchase in markets outside the US. The Ring Pro will continue to be sold in the US until a definitive court ruling dictates otherwise.
