WebSock Global Strategies v. Dynatrace — Voluntary Dismissal in 29 Days
WebSock Global Strategies, LLC filed a patent infringement action against Dynatrace, Inc. in Massachusetts District Court, asserting US7756983B2 covering symmetrical bi-directional communication technology. The case closed just 29 days after filing when the plaintiff voluntarily dismissed without prejudice before Dynatrace had answered or moved for summary judgment.
A 29-day infringement filing that dissolved before Dynatrace could respond
On 17 February 2025, WebSock Global Strategies, LLC filed case 1:25-cv-10396 in the Massachusetts District Court before Judge George A. O’Toole, Jr., asserting infringement of US7756983B2, a patent covering symmetrical bi-directional communication technology. The defendant, Dynatrace, Inc. — an enterprise software and observability platform company — was represented by WilmerHale. Plaintiff counsel was Dickinson Wright PLLC.
On 18 March 2025, just 29 days after filing, WebSock Global invoked Federal Rule of Civil Procedure 41(a)(1)(A)(i) to dismiss the action. That rule permits a plaintiff to dismiss as of right, without court order, provided the defendant has not yet served an answer or moved for summary judgment. The record confirms Dynatrace had done neither, meaning the dismissal required no judicial approval and imposed no merits determination on either party.
A 29-day lifecycle is exceptionally short even by early-dismissal standards, suggesting the decision to withdraw may have been driven by tactical reassessment, licensing dialogue, or identification of a procedural concern — none of which are discernible from the public docket. Because the case ended before substantive engagement, the validity and scope of US7756983B2 remain entirely untested in this proceeding.
Filing to Voluntary dismissal in 29 days
29 days — resolved before defendant could respond, a notably short lifecycle
Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): a unilateral exit before any responsive pleading
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action as of right — with no court order required — as long as the defendant has not yet answered or moved for summary judgment. WebSock Global exercised this right on Day 29. The dismissal is self-executing and carries no merits adjudication. The court plays no gatekeeping role at this stage.
No merits rulingThe public record is silent on refiling rights
The plaintiff’s notice states dismissal ‘without prejudice,’ meaning WebSock Global expressly reserved the right to refile the same claims. A dismissal with prejudice would have permanently barred re-assertion of US7756983B2 against Dynatrace. The distinction is consequential: without prejudice preserves all future enforcement options, subject to applicable statutes of limitations and any subsequent Rule 41 restrictions.
Refiling right preservedDynatrace exits without conceding or winning on the merits
Dynatrace, Inc. faced no adverse ruling and made no substantive concession. Because the case ended before any responsive pleading, Dynatrace incurred minimal litigation exposure in this proceeding. However, the without-prejudice nature of the dismissal means Dynatrace remains exposed to a refiled action on the same patent — and cannot treat this outcome as a final resolution of the infringement allegations.
Re-exposure risk remainsUS7756983B2 remains live and untested — sector exposure persists
No claim construction, no invalidity ruling, and no licence terms were placed on the public record. For companies operating in the symmetrical bi-directional communication and real-time data streaming space — including observability and APM vendors — the patent’s enforceability is unchanged. This dismissal provides no prior art findings or claim-narrowing precedent that competitors could rely on for design-around guidance.

Official order — verbatim text
The plaintiff’s notice invokes Rule 41(a)(1)(A)(i) and expressly confirms that Dynatrace had not answered or moved for summary judgment — the twin preconditions for a unilateral, court-free dismissal. The ‘without prejudice’ designation is legally operative: it means no res judicata effect attaches, and WebSock Global retains the right to reassert US7756983B2 against Dynatrace in a future action. No claim, defence, or invalidity argument was adjudicated.
US7756983B2 — Symmetrical Bi-Directional Communication Technology
US7756983B2, filed under application number US12/109198, protects technology relating to symmetrical bi-directional communication — a foundational architecture enabling simultaneous two-way data transmission between endpoints without the asymmetry typical of traditional client-server request-response models. This class of technology underpins WebSocket protocols, persistent connection frameworks, and real-time data pipelines widely deployed in enterprise software.
The patent’s relevance to the observability and APM sector is direct: platforms like Dynatrace rely on continuous, low-latency data streams between agents and backend systems — precisely the architecture this patent addresses. Because the patent survived this litigation unchallenged, it retains full presumptive validity. Vendors building on bidirectional socket infrastructure should assess whether their implementations fall within the patent’s claim scope, particularly given the without-prejudice dismissal’s refiling optionality.
Should your product team run an FTO against US7756983B2?
Any company deploying symmetrical bi-directional communication architectures — including WebSocket-based real-time telemetry, persistent agent-to-server data channels, or bidirectional HTTP/2 streaming — should assess freedom to operate against US7756983B2. The patent remains valid and enforceable, and this case’s without-prejudice exit means the assertion risk has not been extinguished. APM vendors, cloud observability platforms, and real-time analytics providers are most directly in scope.

What this case signals for the bi-directional communication IP landscape
A 29-day without-prejudice exit rarely signals case resolution — it typically signals a pause, not a conclusion.
Without-prejudice dismissals are a tactical reset, not a surrender
When a plaintiff voluntarily dismisses under Rule 41(a)(1)(A)(i) before the defendant responds, it preserves full optionality. WebSock Global can refile in Massachusetts, another district, or pursue an ITC action. Defendants and industry observers should treat this as a pause in enforcement, not a withdrawal from the field.
Dynatrace faces residual risk — monitoring US7756983B2 is prudent
The patent covering symmetrical bi-directional communication remains in force and unchallenged. APM, observability, and real-time streaming vendors whose products rely on persistent bidirectional socket architectures should track the patent’s status and any continuation filings that may broaden its claim scope.
WebSock v Dynatrace — key questions answered
WebSock Global Strategies filed a patent infringement action against Dynatrace in the Massachusetts District Court on 17 February 2025, asserting US7756983B2 covering symmetrical bi-directional communication. The plaintiff voluntarily dismissed the case without prejudice on 18 March 2025 — 29 days after filing — before Dynatrace had answered or moved for summary judgment.
A dismissal without prejudice means no merits ruling was issued and WebSock Global retains the right to refile the same infringement claims against Dynatrace in the future. Dynatrace received no judicial finding in its favour and cannot rely on this outcome as a final resolution. The patent US7756983B2 remains valid and enforceable.
WebSock Global asserted US7756983B2, filed under application number US12/109198. The patent covers symmetrical bi-directional communication technology — a class of inventions relevant to persistent two-way data channels between software agents and servers, applicable to observability and APM platforms.
The public record does not disclose the reason. A 29-day voluntary dismissal before any responsive pleading typically suggests tactical reassessment, concurrent licensing negotiations, identification of a procedural or jurisdictional issue, or a deliberate pressure-and-pause enforcement strategy. None of these can be confirmed from the docket alone.
No. Because the case was dismissed under Rule 41(a)(1)(A)(i) before any substantive proceedings, no claim construction, validity finding, or merits ruling was issued. The patent’s validity, enforceability, and claim scope remain entirely unaddressed by this litigation, leaving the legal landscape unchanged for third parties.
