WebSock Global Strategies v. Pusher Ltd — Dismissed Without Prejudice in 76 Days
WebSock Global Strategies, LLC asserted US7756983B2 — a patent covering symmetrical bi-directional communication — against real-time messaging infrastructure provider Pusher, Ltd. in Texas federal court. The plaintiff voluntarily dismissed the action without prejudice just 76 days after filing, before the defendant had answered or moved for summary judgment.
Pre-answer voluntary dismissal in the real-time communication patent space
On 2 November 2023, WebSock Global Strategies, LLC filed a patent infringement action against Pusher, Ltd. in the Western District of Texas (Case No. 6:23-cv-00748). The suit centred on US7756983B2, a patent directed at symmetrical bi-directional communication technology — the architectural category that underpins WebSocket-style real-time data channels. Pusher, Ltd. is a well-known provider of real-time messaging APIs and infrastructure used by software developers worldwide.
The case closed on 17 January 2024 when plaintiff WebSock Global Strategies filed a notice of voluntary dismissal without prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). This procedural mechanism is available as of right when the defendant has not yet served an answer or a motion for summary judgment — both of which were absent here, confirming the action ended at its earliest possible stage. Dismissal without prejudice means the claims are not extinguished; WebSock is legally free to refile the same infringement allegations.
A resolution in 76 days, before any substantive litigation milestones, is consistent with several common early-exit scenarios: confidential settlement, licensing negotiation, strategic reassessment by the plaintiff, or a decision to refile in a more favourable venue or against a different defendant. The public record is silent on which factor drove the dismissal. No defendant counsel of record was entered, which suggests Pusher may not have formally engaged litigation counsel before the case ended — or that any engagement occurred outside filed documents.

76 days — resolved before defendant’s first formal response was due
What a Rule 41(a)(1)(A)(i) voluntary dismissal without prejudice means
Rule 41(a)(1)(A)(i): a unilateral exit before the defendant responds
Federal Rule of Civil Procedure 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order — and without the defendant’s consent — provided the defendant has not yet answered or moved for summary judgment. Because Pusher had done neither, WebSock exercised this right unilaterally. No judicial approval was required, and no findings were made on the merits of the infringement claims.
Plaintiff’s unilateral rightWithout prejudice: the claims survive for potential refiling
A dismissal ‘without prejudice’ means the underlying patent claims are not extinguished by res judicata or claim preclusion. WebSock retains the right to assert US7756983B2 against Pusher again in future proceedings. By contrast, a dismissal ‘with prejudice’ would bar refiling. The public record for this case states only ‘without prejudice’ — no settlement, licensing, or other resolution terms are disclosed in the available filings.
Claims may be refiled76-day close with no defendant response on record
The absence of any filed defendant counsel or response within 76 days is notable. It may indicate that engagement between the parties — whether licensing discussion or strategic negotiation — occurred entirely outside the formal docket. Alternatively, Pusher may have been preparing a response when the dismissal was filed. Neither inference can be confirmed from public filings alone, but the pre-answer timing is consistent with early-stage resolution patterns seen in patent assertion campaigns.
Pre-answer resolutionWestern District of Texas: a historically plaintiff-friendly patent forum
The Western District of Texas, particularly the Waco Division, has been one of the most frequently chosen venues for patent assertion cases in recent years. Filing here signals a deliberate forum choice by WebSock’s counsel at Rabicoff Law LLC. The early voluntary dismissal leaves open whether the plaintiff may refile in the same district, a different US venue, or choose not to pursue the matter further — all possibilities that remain consistent with the public record.

Stipulation of dismissal — official text
The dismissal notice invokes Rule 41(a)(1)(A)(i) explicitly and confirms Pusher had neither answered nor moved for summary judgment — the precise conditions that entitle a plaintiff to dismiss as of right. This language is procedurally precise and forecloses any argument that the dismissal required court approval or defendant consent. Critically, no merits finding was made. Neither the validity of US7756983B2 nor Pusher’s alleged infringement was adjudicated, leaving both questions legally open.
US7756983B2 — Symmetrical Bi-Directional Web Communication
US7756983B2 (application number US12/109198) is a granted US patent directed at symmetrical bi-directional communication — a technology class that covers persistent, full-duplex data channels between clients and servers. This architecture is foundational to modern real-time web applications, including chat platforms, live dashboards, collaborative tools, and event-driven APIs. The patent’s symmetrical framing suggests claims directed at communication protocols where both endpoints share equivalent send-and-receive capabilities, distinguishing it from earlier asymmetric request-response HTTP models.
In a sector where WebSocket and WebSocket-adjacent technologies are embedded in virtually every real-time developer platform, a granted patent in this space carries meaningful strategic weight. Pusher’s core product — hosted WebSocket channels for developers — sits squarely within the product category identified in this litigation. Other companies building real-time SDKs, push notification infrastructure, or event streaming services should assess whether their implementations overlap with the claim scope of US7756983B2, particularly given the patent holder’s demonstrated willingness to assert it in federal court.
Should your product team run an FTO against US7756983B2?
Any product team building or shipping real-time communication features — WebSocket servers, persistent HTTP channels, bidirectional API layers, or real-time event streams — should consider a freedom-to-operate review against US7756983B2. The fact that this patent has already been asserted in federal court confirms it is being actively monitored and enforced. Companies in adjacent markets, including collaborative software, gaming backends, IoT telemetry, and financial data feeds, face non-trivial exposure if their bi-directional channel implementations fall within the patent’s independent claims.

What this case signals for the real-time communication IP landscape
A fast, pre-answer dismissal without prejudice keeps all strategic options open for the patent holder — and raises uncertainty for companies in the WebSocket and messaging API space.
Pusher is not cleared — the patent threat remains live
Dismissal without prejudice provides Pusher with no legal shield against future assertion of US7756983B2. Any company in the real-time messaging or WebSocket infrastructure space whose products involve symmetrical bi-directional communication should treat this patent as an active risk. A freedom-to-operate analysis against US7756983B2 remains relevant for Pusher and similarly positioned competitors.
Pre-answer exits are a recognised tactic in patent assertion campaigns
Cases filed by dedicated patent assertion entities and dismissed this quickly — before the defendant formally appears — are often consistent with licensing-first strategies: file, initiate dialogue, and exit if a deal is reached or if the target proves difficult to monetise. The Rabicoff Law LLC firm has filed patent infringement cases across multiple defendants and technology domains, suggesting a systematic enforcement approach worth monitoring.
WebSock v Pusher — key questions answered
WebSock Global Strategies, LLC filed a patent infringement suit against Pusher, Ltd. in the Western District of Texas on 2 November 2023, asserting US7756983B2 covering symmetrical bi-directional communication. The plaintiff voluntarily dismissed the action without prejudice on 17 January 2024 under Rule 41(a)(1)(A)(i), 76 days after filing, before Pusher had answered the complaint.
Dismissal without prejudice means Pusher has not been cleared of infringement. No court ruling was made on the merits, and WebSock Global Strategies retains the legal right to refile the same claims based on US7756983B2 against Pusher in the future. Pusher receives no res judicata protection from this dismissal.
US7756983B2 is a granted US patent covering symmetrical bi-directional communication technology — the architectural category underpinning WebSocket-style real-time data channels. Pusher provides hosted WebSocket API infrastructure widely used by developers for real-time messaging, making it a plausible target for assertion of a patent in this technical domain.
Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure allows a plaintiff to dismiss an action as of right — without court approval or the defendant’s consent — as long as the defendant has not yet served an answer or a motion for summary judgment. WebSock invoked this rule after Pusher had taken neither step, making the dismissal automatic and unilateral.
WebSock Global Strategies was represented by Rabicoff Law LLC, with attorney Isaac Rabicoff listed as plaintiff’s agent. No defendant law firm or counsel of record appears in the available case filings, consistent with the action closing before Pusher formally appeared in the litigation.
