Bardy Diagnostics v. Vital Connect: ECG Patch Patents Dismissed With Prejudice After 959 Days
Bardy Diagnostics filed suit in the Delaware District Court alleging that Vital Connect’s VitalPatch biosensor line infringed two wearable ECG monitoring patents. After nearly three years of litigation, both parties stipulated to dismiss all claims and counterclaims with prejudice, each bearing its own costs.
A near-three-year ECG patch dispute ends at the Delaware courthouse door
On 18 March 2022, Bardy Diagnostics, Inc. — developer of the CAM™ patch cardiac ambulatory monitor — filed a patent infringement action in the District of Delaware against Vital Connect, Inc., asserting two patents: US11051743B2 and US11445967B2, both directed at wearable electrocardiography monitoring technology. The accused products included the VitalPatch 1.0, 1.5, 2.0, VitalPatch RTM, and the broader VitalConnect Sensor biosensor platform.
The case closed on 1 November 2024 via a stipulated dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Both Bardy Diagnostics and Vital Connect agreed to dismiss all claims and counterclaims, with each side absorbing its own legal costs. A dismissal with prejudice is a final adjudication on the merits — Bardy cannot re-assert these patents against Vital Connect on the same accused products in any future action.
At 959 days, the timeline suggests the parties engaged in substantial pre-trial proceedings — likely including claim construction and potentially inter partes review activity — before reaching resolution. The absence of any fee-shifting award is consistent with a negotiated settlement rather than a one-sided capitulation, though the precise commercial terms, if any, remain undisclosed on the public docket. What drove the parties to dismiss rather than proceed to trial is unknown from the public record.

Dismissed with prejudice: what the stipulated exit means for both parties
Rule 41(a)(1)(A)(ii) dismissal with prejudice explained
A stipulated dismissal under Rule 41(a)(1)(A)(ii) requires the consent of all parties and operates as a final judgment on the merits when entered with prejudice. Unlike a court-ordered dismissal, this route gives both sides full control over timing and terms. The ‘with prejudice’ designation is legally significant: it bars Bardy Diagnostics from re-filing the same patent claims against Vital Connect on the same accused products in any U.S. federal court.
Bilateral consent, final on meritsBardy forecloses re-assertion — what that signals
By agreeing to dismiss with prejudice, Bardy Diagnostics permanently relinquishes its infringement claims under US11051743B2 and US11445967B2 against Vital Connect’s VitalPatch line. This outcome is more restrictive than a without-prejudice dismissal, which would preserve the option to re-litigate. Whether Bardy extracted a licence, royalty, or design-around commitment from Vital Connect in exchange is not disclosed on the public record, but the mutual cost-bearing clause suggests a commercially balanced resolution.
Claims barred from re-filingVital Connect closes the litigation risk on VitalPatch
For Vital Connect, the with-prejudice dismissal effectively extinguishes Bardy’s threat to its VitalPatch 1.0, 1.5, 2.0, RTM, and broader VitalConnect Sensor products under these two patents. The company avoids a jury verdict, an injunction, or a damages award. However, the patents themselves remain valid and enforceable against other parties — Vital Connect’s protection is specific to this stipulation, not a broader invalidation of Bardy’s IP.
Litigation risk cleared for VitalPatchBardy’s ECG patch patents remain active competitive weapons
US11051743B2 and US11445967B2 survive this litigation fully intact and enforceable. The dismissal is party-specific — it does not invalidate any claims, create prosecution history estoppel against third parties, or signal weakness in the patent portfolio. Other wearable ECG monitor manufacturers operating in adjacent product spaces should note that Bardy’s enforcement posture remains active. The 959-day duration suggests these patents withstood scrutiny long enough to warrant a negotiated exit.

Official order — verbatim text
The stipulation invokes Rule 41(a)(1)(A)(ii), the bilateral dismissal mechanism requiring written consent from all parties. The phrase ‘with prejudice’ is the operative legal term: it converts the voluntary exit into a final judgment on the merits, permanently barring Bardy from reasserting these claims against Vital Connect on these products. The mutual cost-bearing clause — ‘each party shall bear its own costs and fees’ — is standard in negotiated resolutions and forecloses any subsequent fee motion under 35 U.S.C. § 285. The stipulation’s symmetry suggests a commercially negotiated conclusion rather than a unilateral capitulation by either party.
US11051743B2 & US11445967B2 — Wearable ECG Biosensor Patch Technology
US11051743B2 (application US17/119945) and US11445967B2 (application US17/367476) are utility patents assigned to Bardy Diagnostics covering wearable electrocardiography monitoring technology. The patents protect structural and functional aspects of patch-form cardiac monitors — including features consistent with the CAM™ patch architecture, such as an elongated backing strip configured for sustained body-worn ECG acquisition. Both patents sit within the rapidly expanding wearable cardiac diagnostics space, where miniaturisation and continuous ambulatory monitoring have become central clinical and commercial differentiators.
These patents represent Bardy’s offensive IP position against direct competitors in the wearable biosensor patch market. The asserted product set — VitalPatch 1.0 through RTM — indicates that Bardy viewed Vital Connect’s entire commercial ECG wearable line as potentially infringing. For sector participants, this patent family signals that Bardy actively monitors the competitive landscape and is willing to litigate in a major patent venue. The 959-day case duration, ending without invalidation, suggests the patents demonstrated sufficient claim resilience to sustain extended litigation.
Should you run an FTO against US11051743B2 and US11445967B2?
Any company developing, manufacturing, or commercialising wearable ECG monitoring patches — particularly those featuring elongated flexible backing strips, body-worn electrode configurations, or continuous ambulatory cardiac monitoring methods — should treat these two Bardy patents as priority FTO targets. The patents survived nearly three years of adversarial litigation without invalidation, and the dismissal is party-specific: it provides no protection to any third-party biosensor or cardiac patch manufacturer.

Portfolio viewWhat this case signals for the wearable cardiac monitoring IP landscape
A long-running ECG patch dispute resolved bilaterally — with lasting implications for biosensor patent enforcement strategy.
With-prejudice exits protect defendants but leave patents intact
Vital Connect secured permanent protection against these specific claims, but Bardy’s patents remain in force. Any competitor in the wearable ECG or biosensor patch market should treat US11051743B2 and US11445967B2 as live enforcement risks and audit product overlap before commercialising.
Mutual cost-bearing suggests neither side had a clear upper hand
The absence of fee-shifting in a 959-day case is a notable signal. Courts award fees under 35 U.S.C. § 285 in ‘exceptional’ cases. The parties’ decision to each bear their own costs is consistent with a negotiated resolution where neither side had achieved decisive litigation leverage.
CAM patch claim scope warrants independent FTO analysis before product launch
The asserted patents cover structural and functional features of wearable ECG patches — including elongated backing strips and cardiac ambulatory monitoring methods. Any product in this category that shares form-factor or sensing methodology with the CAM patch should be stress-tested against both patents’ independent claims before market entry.
Delaware venue and Burke’s docket: timing dynamics for biosensor defendants
Judge Burke’s District of Delaware docket has consistent case management patterns. A 959-day lifecycle in this court suggests the case likely passed through Markman proceedings before settlement pressure peaked. Defendants in similar ECG patent suits should model claim construction outcomes as a key settlement inflection point.
Bardy v Vital — key questions answered
The case was dismissed with prejudice on 1 November 2024 via a stipulated dismissal under Rule 41(a)(1)(A)(ii). Both parties agreed to dismiss all claims and counterclaims, with each side bearing its own costs and fees. The with-prejudice designation bars Bardy from re-asserting the same claims against Vital Connect.
Bardy asserted US11051743B2 (application US17/119945) and US11445967B2 (application US17/367476), both covering wearable electrocardiography monitoring patch technology. The patents relate to structural and functional features of body-worn cardiac ambulatory monitors, including elongated backing strip electrode configurations.
The accused products included the VitalConnect Sensor, VitalPatch 1.0, VitalPatch 1.5, VitalPatch 2.0, VitalPatch Biosensor, and VitalPatch RTM — Vital Connect’s full commercial wearable ECG biosensor patch line. The CAM™ patch was identified as Bardy’s leading reference product.
No. A Rule 41(a)(1)(A)(ii) stipulated dismissal with prejudice is party-specific. It bars Bardy from re-suing Vital Connect on these patents for the same products, but it does not invalidate any patent claims, establish any claim construction ruling, or limit enforcement against other third parties. US11051743B2 and US11445967B2 remain fully enforceable.
The mutual cost-bearing clause means neither party was awarded attorneys’ fees or litigation costs by the court. This forecloses any subsequent fee motion under 35 U.S.C. § 285. It is commonly seen in negotiated resolutions and suggests a commercially balanced exit, though it does not confirm or deny whether any private financial terms were exchanged between the parties.
