Ouraring v. RingConn: Smart Ring Patent Suit Dismissed With Prejudice
Ouraring, Inc. filed suit against RingConn LLC in Delaware District Court, asserting two patents covering smart ring wearable technology against the RingConn Gen. 1 and Gen. 2 smart rings. After 399 days, Ouraring voluntarily dismissed all claims with prejudice before RingConn filed any answer, closing the door on re-litigation of the same claims.
Smart ring IP clash ends before RingConn files a single pleading
On September 10, 2024, Ouraring, Inc. filed a patent infringement complaint against RingConn LLC in the U.S. District Court for the District of Delaware before Judge Maryellen Noreika. The suit asserted two patents — US11188124B2 and US11868178B2 — against RingConn’s Gen. 1 and Gen. 2 smart rings, targeting technology central to the rapidly expanding wearable health-monitoring market.
On October 14, 2025, Ouraring filed a notice of voluntary dismissal under Fed. R. Civ. P. 41(a)(1)(A)(i), dismissing all claims with prejudice. Because RingConn had not yet served an answer or a motion for summary judgment, Ouraring was entitled to dismiss unilaterally as of right. The with-prejudice designation, however, was a deliberate choice — it permanently bars Ouraring from reasserting the same claims against RingConn on these patents.
A 399-day case lifecycle ending before any substantive defence pleading is filed is notable. The timeline suggests the parties may have engaged in licensing negotiations, settlement discussions, or that Ouraring reassessed the strength of its infringement position after closer analysis. The public record does not disclose any settlement agreement, licensing arrangement, or payment, leaving the commercial resolution — if any — undisclosed.

Dismissed with prejudice: what Ouraring’s Rule 41 filing means for both parties
Rule 41(a)(1)(A)(i) dismissal with prejudice — a one-way door
Fed. R. Civ. P. 41(a)(1)(A)(i) permits a plaintiff to dismiss without court approval before the defendant serves an answer or a summary judgment motion. Ouraring invoked this right but added a with-prejudice designation — meaning the dismissal carries the same claim-preclusive effect as a final judgment on the merits. Ouraring cannot refile the same patent claims against RingConn in any U.S. court.
Claim-preclusive dismissalOuraring permanently relinquishes these specific claims against RingConn
By electing a with-prejudice dismissal, Ouraring forfeits the right to reassert US11188124B2 and US11868178B2 against RingConn on the accused Gen. 1 and Gen. 2 products. This is an unusually strong concession at such an early stage. It may reflect a strategic pivot — potentially a negotiated resolution, a licensing outcome, or a reassessment of claim scope — though none of these possibilities is confirmed by the public record.
No re-litigation possibleRingConn exits litigation without filing a defence — a significant shield
RingConn LLC secured a permanent end to this litigation without serving an answer, incurring the cost of substantive defence pleadings, or facing any adverse merits ruling. The with-prejudice dismissal functions as a permanent shield against Ouraring reasserting these specific patents. However, Ouraring could theoretically assert different patents or different claim theories, and other patent holders remain free to bring independent actions.
Protected from re-suit on these patentsSmart ring IP landscape remains contested despite early exit
The voluntary dismissal resolves this dispute but does not resolve the broader competitive tension in the smart ring wearable sector. RingConn’s Gen. 1 and Gen. 2 products remain on the market. The patents-in-suit — directed at smart ring wearable technology — remain active and enforceable against other parties. Competitors in the wearable ring health-monitoring space should treat this outcome as a signal to conduct FTO analysis, not as a clearance event.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) — the mechanism available to a plaintiff before any responsive pleading is served — but critically appends a with-prejudice designation. This is not the default outcome of a Rule 41(a)(1) filing and represents a deliberate, binding choice by Ouraring. The practical effect is permanent claim preclusion: the same patent claims against RingConn’s accused products cannot be reasserted. No merits adjudication occurred, and no finding of infringement, validity, or invalidity was made.
US11188124B2 & US11868178B2 — Smart Ring Wearable Health Technology
US11188124B2 (App. No. US17/013348) and US11868178B2 (App. No. US18/323385) cover technology in the smart ring wearable domain — a class of miniaturised ring-form-factor devices designed to continuously monitor biometric and health data. These patents are directed at a segment of wearable technology where extreme hardware miniaturisation, sensor integration, and continuous health tracking must coexist in a finger-worn device, presenting significant engineering constraints that distinguish ring-form IP from conventional wrist-worn wearable patents.
The smart ring wearable market has attracted major commercial players and generated intense IP activity, with Ouraring, Inc. positioning itself as an originating innovator in ring-form biometric sensing. Asserting two patents against a direct competitor’s Gen. 1 and Gen. 2 product lines signals a portfolio enforcement strategy. For competing wearable companies — particularly those developing ring-form health monitors — these patents represent active risk assets that survived litigation without any adverse validity ruling, making them credible enforcement vehicles going forward.
Should your team run an FTO against US11188124B2 and US11868178B2?
Any company designing, manufacturing, or commercialising ring-form wearable devices with health monitoring, biometric sensing, or activity tracking functionality should treat these two patents as priority FTO targets. The dismissal of the RingConn action with prejudice does not affect the patents’ enforceability against third parties. No court has assessed claim scope, validity, or prior art — meaning the patents carry full presumptive validity and untested claim breadth.
PatSnap Eureka’s FTO Search Agent can map your product’s technical architecture against the independent and dependent claims of US11188124B2 and US11868178B2, identify relevant prior art that was not considered during prosecution, and surface related family members or continuation applications that may present additional exposure. R&D teams building ring-form health sensors should run this analysis before finalising hardware specifications.

What this case signals for the smart ring wearable IP landscape
An early with-prejudice exit in a wearable patent suit often signals more than it reveals. Here is what IP teams should take away.
With-prejudice dismissal before answer is a rare and deliberate concession
Plaintiffs rarely choose with-prejudice at the Rule 41(a)(1)(A)(i) stage — the default is without prejudice. Ouraring’s deliberate election suggests either a negotiated resolution that required finality, or a strategic decision to exit cleanly. Either way, the legal effect is identical to losing on the merits for purposes of claim preclusion against RingConn.
US11188124B2 and US11868178B2 remain live threats for other smart ring makers
The dismissal only protects RingConn. Any other company operating in the smart ring or wearable health sensor space — particularly those competing on form factor, continuous health monitoring, or ring-based biometric sensing — should independently assess exposure to both asserted patents before commercialising overlapping products.
Ouraring v RingConn — key questions answered
The with-prejudice dismissal means Ouraring permanently relinquished its right to sue RingConn on US11188124B2 and US11868178B2 for the accused Gen. 1 and Gen. 2 products. RingConn faces no further liability risk from Ouraring on these specific claims. The patents remain enforceable against other parties.
Ouraring asserted two patents: US11188124B2 (application number US17/013348) and US11868178B2 (application number US18/323385). Both patents relate to smart ring wearable technology and were asserted against RingConn’s Gen. 1 and Gen. 2 smart ring products.
The public record does not disclose the reason. Under Rule 41(a)(1)(A)(i), Ouraring was entitled to dismiss as of right because RingConn had not yet served an answer. The with-prejudice election was voluntary and unusual at this stage, suggesting a negotiated resolution, licensing arrangement, or strategic reassessment — though none is confirmed by filed documents.
No. A voluntary dismissal with prejudice carries no finding on the merits. No court adjudicated the validity, invalidity, or infringement scope of either patent. Both patents retain their full presumption of validity under 35 U.S.C. § 282 and remain enforceable against any party other than RingConn in this specific context.
The case was filed in the U.S. District Court for the District of Delaware and assigned to Judge Maryellen Noreika. Plaintiff Ouraring was represented by Young Conaway Stargatt & Taylor, LLP (Karen L. Pascale and Robert M. Vrana). Defendant RingConn was represented by Ashby & Geddes PC (Andrew Colin Mayo and Robert M. Breetz).
