Oura vs. RingConn: Voluntary Dismissal Ends Smart Ring Patent Battle

Updated on Dec. 1, 2025 | Written by Patsnap Team

Introduction

In a notable development for wearable technology patent litigation, Ouraring, Inc. voluntarily dismissed its patent infringement claims against RingConn LLC with prejudice on October 14, 2025. The dismissal came before RingConn filed any responsive pleading, ending a 399-day legal dispute in Delaware District Court over smart ring health monitoring technology.

This Oura RingConn patent case analysis examines what happened when two competitors in the smart ring market faced off over patents US11188124B2 and US11868178B2. The voluntary dismissal with prejudice—meaning Ouraring cannot refile these claims—raises strategic questions about settlement dynamics, patent strength assessments, and competitive positioning in consumer health wearables.

💡 Key Insight: A voluntary dismissal with prejudice before any defensive filing suggests a strategic resolution, potentially involving confidential settlement terms or a reassessment of litigation viability.
