WebSock Global Strategies v. Critical Start: Dismissed With Prejudice in 113 Days
WebSock Global Strategies, LLC asserted US7756983B2 — a patent covering symmetrical bi-directional communication — against cybersecurity firm Critical Start, Inc. in the Eastern District of Texas. The case ended in a voluntary dismissal with prejudice after just 113 days, before the defendant filed an answer, with each party bearing its own costs.
An Early-Stage Infringement Claim Ends Before Defendant Responds
On November 12, 2024, WebSock Global Strategies, LLC filed a patent infringement action against Critical Start, Inc. in the U.S. District Court for the Eastern District of Texas (Case No. 2:24-cv-00922), before Judge Rodney Gilstrap. The sole patent asserted was US7756983B2, directed to symmetrical bi-directional communication technology — a foundational connectivity concept with broad applicability in networked cybersecurity platforms of the kind Critical Start operates.
The case closed on March 5, 2025 — just 113 days after filing — when WebSock filed a Notice of Voluntary Dismissal With Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). The court accepted and acknowledged the dismissal, formally extinguishing all of WebSock’s claims against Critical Start with prejudice. Critically, dismissal occurred before Critical Start had filed an answer or moved for summary judgment, meaning no merits ruling was issued. Each party was ordered to bear its own costs, attorneys’ fees, and expenses.
The speed of resolution — and the with-prejudice designation — is commercially significant. A dismissal with prejudice at this early stage typically suggests the parties reached some form of private resolution, or that the plaintiff concluded the case could not proceed on viable grounds. The public record is silent on whether any licensing agreement or settlement payment accompanied the dismissal. What is clear is that WebSock has permanently relinquished its right to bring this specific claim against Critical Start under US7756983B2.

Dismissed with prejudice: what the Rule 41 filing means for both parties
Rule 41(a)(1)(A)(i) dismissal with prejudice explained
Under Rule 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss an action without a court order if filed before the defendant serves an answer or a summary judgment motion. By electing dismissal with prejudice, WebSock permanently forfeited its right to reassert these specific infringement claims against Critical Start. The court’s role was limited to accepting and acknowledging the notice — no merits adjudication occurred.
Permanent bar on re-filingWebSock permanently relinquishes its claim against Critical Start
A with-prejudice dismissal is a final disposition on the merits for res judicata purposes — WebSock cannot bring the same infringement claims under US7756983B2 against Critical Start in any future action. This is a significant concession. Whether it reflects a private settlement, a licensing agreement, or a strategic withdrawal is not disclosed in the public record. WebSock retains the patent and may assert it against other defendants.
Claims extinguished as to this defendantCritical Start exits with full claim bar and no cost exposure
Critical Start achieved a with-prejudice dismissal without filing an answer, incurring no public merits risk. The each-party-bears-own-costs order means Critical Start absorbs its own defence costs but faces no fee-shifting liability. Practically, Critical Start is fully shielded from this specific patent claim going forward. The absence of a merits ruling means no claim construction or invalidity findings are on the public record.
Full protection, no fee awardUS7756983B2 remains active — risk persists for other bi-directional communication players
WebSock’s retention of US7756983B2 post-dismissal means the patent can still be asserted against other companies in the networked communication and cybersecurity space. No invalidity ruling or claim construction was issued in this case, leaving the patent’s scope untested in litigation. Companies deploying symmetrical bi-directional communication protocols — particularly in security operations platforms — should monitor this patent’s enforcement history closely.

Official order — verbatim text
The court’s order is procedural in character: it accepts and acknowledges WebSock’s Rule 41(a)(1)(A)(i) notice and formally records the with-prejudice dismissal. No claim construction, validity finding, or infringement analysis was conducted. The denial of all pending relief as moot confirms no substantive rulings survived the dismissal. For both parties, the operative effect is a permanent bar on re-litigation of these specific claims — but the absence of a merits ruling means neither side secured any precedential advantage or judicial validation of their legal position.
US7756983B2 — Symmetrical Bi-Directional Communication Technology
US7756983B2 (application number US12/109198) claims technology directed to symmetrical bi-directional communication — a paradigm in which data flows in both directions simultaneously and equivalently between connected endpoints. This architecture underpins a wide range of modern networked applications, from real-time security telemetry to WebSocket-based communication layers. The patent’s technical scope, while not adjudicated in this proceeding, appears relevant to platforms that maintain persistent, two-way data channels between agents and centralised processing infrastructure.
In the cybersecurity sector, symmetrical bi-directional communication is foundational to managed detection and response (MDR) platforms, security information and event management (SIEM) systems, and endpoint detection tools — all of which depend on continuous, low-latency two-way data exchange. Assertion of this patent against Critical Start, a prominent MDR provider, suggests the patent holder views these architectures as within scope. With no invalidity or non-infringement finding on record, the patent presents residual risk for any company operating similar real-time communication infrastructure.
Should your team run an FTO analysis against US7756983B2?
Any organisation developing or commercialising platforms that use persistent, symmetrical bi-directional communication channels — including MDR services, SIEM platforms, endpoint detection tools, and real-time security analytics infrastructure — should assess exposure to US7756983B2. The patent was asserted against a major cybersecurity vendor, signalling that the holder views commercial security platforms as within its scope. With no court-issued claim construction available, the patent’s boundaries remain undefined from a litigation standpoint.

What this case signals for the cybersecurity communication IP landscape
An early with-prejudice exit in EDTX raises key questions about assertion strategy and portfolio risk for bi-directional communication patents.
With-prejudice dismissals before answer often signal private resolution
When a plaintiff voluntarily dismisses with prejudice before the defendant has responded, it typically suggests a private agreement — licensing, settlement, or covenant not to sue — was reached off the record. Companies receiving similar demand letters from WebSock or related entities should assess whether a licensing posture is driving the litigation programme.
No merits ruling leaves US7756983B2 scope legally untested
Because the case ended before claim construction or summary judgment, there is no public judicial guidance on the scope or validity of US7756983B2. For competitors and adjacent product teams, this means the patent’s enforceability remains an open question — and a future defendant would need to build invalidity arguments from scratch.
WebSock v Critical — key questions answered
The case was dismissed with prejudice. WebSock Global Strategies filed a Notice of Voluntary Dismissal With Prejudice under Rule 41(a)(1)(A)(i) on or before March 5, 2025. The Eastern District of Texas accepted the notice, permanently barring WebSock from reasserting the same claims under US7756983B2 against Critical Start, Inc.
The sole patent asserted was US7756983B2, filed under application number US12/109198. The patent covers symmetrical bi-directional communication technology. The case was filed in the Eastern District of Texas before Judge Rodney Gilstrap.
No. The court’s order specified that each party is to bear its own costs, expenses, and attorneys’ fees. No damages award, fee-shifting order, or sanctions were issued. Critical Start exited the litigation without any financial liability on the public record.
Under Rule 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order before the defendant answers or moves for summary judgment. When filed with prejudice, the dismissal operates as a final adjudication on the merits, permanently barring the plaintiff from refiling the same claims against the same defendant. Critical Start is fully protected from future WebSock claims under US7756983B2.
The public record does not disclose the reason for the with-prejudice dismissal. Common explanations in comparable cases include a private settlement or licensing agreement reached between the parties, a covenant not to sue, or a strategic reassessment by the plaintiff. The early timing — before Critical Start filed an answer — is consistent with a negotiated exit, though this cannot be confirmed from available court documents.
