Oura Files New Patent Complaint Against Ultrahuman Over Ring Pro

Oura said Oct. 23 that it had filed a new patent complaint against Ultrahuman, opening a separate legal dispute over the rival’s Ring Pro. Oura alleges the redesigned smart ring continues to infringe its intellectual property.

Oura said the complaint was filed in the U.S. District Court for the Eastern District of Texas and asserts additional design and utility patents. The announcement did not identify the patents in the new case. The allegations are separate from an earlier trade dispute involving Oura and smart-ring makers Ultrahuman and RingConn.

On Aug. 21, 2025, the U.S. International Trade Commission (ITC) found a Section 337 violation involving claims 1, 2 and 12–14 of Oura patent 11,868,178. The ITC issued a limited exclusion order and cease-and-desist orders against Ultrahuman and RingConn.

U.S. Customs and Border Protection (CBP) ruled on March 6, 2026, that Ring Pro, as described in Ultrahuman’s request, was not subject to entry exclusion under that limited exclusion order. Entry remained subject to requirements that included an approved certification. The ruling addressed the earlier order’s application to the product described in the request; it did not resolve Oura’s new patent allegations.

Ultrahuman announced Ring Pro in February 2026, initially leaving the United States out of its launch. The company opened U.S. preorders on March 24, after the CBP ruling. That sequence concerns entry under the earlier trade order and does not determine the outcome of Oura’s new complaint.

Oura’s announcement confirms that it is asserting additional design and utility patents against Ultrahuman. The new case therefore raises allegations beyond the specific claims in patent 11,868,178 addressed in the ITC trade dispute. The complaint details identified in Oura’s announcement do not specify which additional patents are at issue.
