XMARK Corp. v. Inzwa Technologies: Vibration Sensor Patent Dismissed With Prejudice
XMARK Corp. asserted US10794929B2 — covering the Veva III environmental monitoring and vibration sensor system — against Inzwa Technologies LLC in the Western District of Pennsylvania. The parties reached a stipulated dismissal with prejudice after 299 days, with each side bearing its own costs.
Stipulated exit: XMARK and Inzwa settle vibration sensor dispute quietly
On 4 January 2024, XMARK Corp. filed an infringement action against Inzwa Technologies LLC in the U.S. District Court for the Western District of Pennsylvania (Case No. 2:24-cv-00048), asserting US10794929B2. The patent relates to a vibration sensor system, commercially embodied in the Veva III environmental monitoring sensor. XMARK was represented by Leason Ellis LLP and Salmanson Goldshaw PC, while Inzwa retained Andrew Koopman as counsel.
On 29 October 2024 — 299 days after filing — the parties filed a stipulated dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The dismissal is bilateral and court-approved by stipulation, meaning XMARK permanently relinquishes its right to reassert the same claims against Inzwa on the same patent. Each party agreed to bear its own costs and fees, suggesting no monetary judgment or explicit royalty arrangement was publicly disclosed.
A with-prejudice dismissal at this stage — before any reported claim construction hearing or trial — is consistent with the parties having reached a private resolution, whether licensing, design-around, or commercial agreement. The symmetric cost-bearing provision suggests neither party extracted a concession significant enough to warrant fee-shifting. The terms of any underlying agreement remain confidential and are not reflected in the public docket.

Dismissed with prejudice: what the stipulated exit means for both parties
Rule 41(a)(1)(A)(ii): stipulated dismissal, permanent bar on refiling
A dismissal with prejudice under Rule 41(a)(1)(A)(ii) requires a signed stipulation from all parties. Unlike a voluntary dismissal without prejudice, this closes the door permanently — XMARK cannot refile this infringement action against Inzwa on US10794929B2 based on the same conduct. The court need not enter a separate order; the stipulation itself operates as a final disposition.
Permanent claim barXMARK surrenders its right to pursue Inzwa on this patent
By agreeing to dismissal with prejudice, XMARK Corp. permanently waives its infringement claims against Inzwa on US10794929B2. The patent itself remains valid and enforceable against other parties, but XMARK cannot use this litigation vehicle again against Inzwa for the same accused conduct. This outcome is consistent with a negotiated resolution — licensing grant, design-around acceptance, or commercial settlement — the terms of which are not publicly available.
Patent survives; claims extinguished vs. InzwaInzwa achieves certainty — but terms remain confidential
For Inzwa Technologies LLC, the with-prejudice dismissal provides legal certainty: XMARK cannot revive these specific claims. The equal cost-bearing arrangement suggests Inzwa did not extract an admission of non-infringement or invalidity on the record. Any underlying agreement — such as a cross-license or product modification — would govern ongoing commercial exposure but is not reflected in public filings.
Claims resolved; no public admissionVibration sensor IP remains live risk for other market players
US10794929B2 survives this litigation intact. Competitors and new entrants in the environmental monitoring and vibration sensor space should treat XMARK’s enforcement action as a signal of active portfolio assertion. The swift resolution — under 300 days, before claim construction — suggests XMARK may prefer licensing over prolonged litigation, a posture that has implications for how third parties approach FTO analysis in this technology domain.

Official order — verbatim text
The stipulation invokes Rule 41(a)(1)(A)(ii), the joint-dismissal mechanism that operates without court order once filed by all parties. The ‘with prejudice’ designation is the critical operative term: it converts what might have been a temporary pause into a permanent bar on XMARK refiling these claims against Inzwa. The mutual cost-bearing clause is a standard negotiating symmetry that avoids either party triggering an ‘exceptional case’ fee motion under 35 U.S.C. § 285. No merits determination was recorded.
US10794929B2 — Vibration sensor system and environmental monitoring technology
US10794929B2, filed under application number US16/067333, protects a vibration sensor system in the environmental monitoring technology domain. The patent is commercially associated with XMARK’s Veva III sensor platform, which is designed to detect and characterise vibration events in industrial or infrastructure environments. The granted patent designation (B2) indicates it has undergone examination with amended claims, suggesting the claim scope has been refined through prosecution history.
For competitors in the IoT sensor, structural health monitoring, and industrial environmental sensing markets, US10794929B2 represents an active enforcement risk. XMARK’s willingness to file in federal court and pursue litigation to a with-prejudice resolution — consistent with a licensing outcome — signals a commercially assertive IP posture. Any product that captures, processes, or transmits vibration or environmental sensor data should be evaluated against the claim scope of this patent before market entry or product refresh.
Should you run an FTO analysis against US10794929B2?
If your organisation develops, manufactures, or deploys vibration sensing systems, environmental monitoring hardware, or IoT sensor platforms — particularly products in the Veva III competitive space — US10794929B2 warrants a dedicated freedom-to-operate review. XMARK’s demonstrated willingness to assert this patent in federal litigation makes reactive FTO analysis a commercial necessity, not a precaution.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map product features against the claim language of US10794929B2, surface relevant prior art, and identify potential design-around opportunities. Given that this case closed before claim construction, the full scope of enforceable claims has not been publicly adjudicated — making proactive claim mapping especially important for any team entering this technology space.

What this case signals for the vibration sensor and IoT monitoring IP landscape
A fast, quiet dismissal with prejudice in W.D. Pa. tells a nuanced story about patent assertion strategy in environmental sensing.
Pre-claim construction settlement signals licensing-forward enforcement posture
The case closed before any substantive claim construction activity on the public docket. Resolving within 299 days at this stage is consistent with a plaintiff willing to convert litigation into a licensing relationship rather than pursue an invalidation risk at Markman. Companies operating in the vibration sensor space should assess whether a licensing approach is more cost-effective than protracted litigation defense.
US10794929B2 remains a live enforcement asset despite this dismissal
A with-prejudice dismissal extinguishes claims only against Inzwa Technologies for the conduct at issue. XMARK Corp. retains full rights to assert US10794929B2 against other parties. Any company deploying vibration sensor or environmental monitoring technology in overlapping claim space should treat this case as a marker of XMARK’s active enforcement intent — not a signal that the patent is exhausted or weakened.
XMARK v Inzwa — key questions answered
The dismissal with prejudice extinguishes XMARK’s infringement claims against Inzwa Technologies only. US10794929B2 remains valid and fully enforceable against all other parties. XMARK retains the right to assert this patent in future actions against different defendants.
US10794929B2 is a U.S. patent covering a vibration sensor system associated with XMARK Corp.’s Veva III environmental monitoring sensor platform. The patent protects sensor technology used to detect and characterise vibration in industrial or environmental monitoring applications.
The public record does not disclose the reasons. However, a stipulated with-prejudice dismissal before claim construction — with symmetric cost-bearing — is consistent with a private resolution such as a licensing agreement, product redesign, or commercial settlement. No merits determination was made.
Symmetric cost-bearing means neither party sought or obtained fee-shifting under 35 U.S.C. § 285, which requires a finding of an ‘exceptional case’. This arrangement typically signals a negotiated, balanced resolution and avoids any implication that one party’s litigation position was objectively unreasonable.
No. A dismissal with prejudice under Rule 41(a)(1)(A)(ii) permanently bars XMARK from refiling the same infringement claims against Inzwa Technologies based on the same accused conduct and patent. The dismissal operates as a final adjudication on those specific claims.
