WebSock Global Strategies v. NAVER Corp: Dismissed With Prejudice in 133 Days
WebSock Global Strategies, LLC asserted US7756983B2 — a patent covering symmetrical bi-directional communication — against South Korean internet giant NAVER Corporation in the Eastern District of Texas. The plaintiff voluntarily dismissed the case with prejudice after just 133 days, foreclosing any future re-filing on the same claims.
A WebSocket patent assertion against NAVER ends abruptly — and permanently
On August 4, 2025, WebSock Global Strategies, LLC filed suit against NAVER Corporation in the Eastern District of Texas (Case No. 2:25-cv-00760) before Judge Rodney Gilstrap, one of the nation’s most experienced patent trial judges. The single asserted patent, US7756983B2, relates to symmetrical bi-directional communication — technology closely associated with the WebSocket protocol that underpins real-time web applications. NAVER, a major South Korean technology conglomerate operating search, messaging, and cloud services, was the sole defendant.
The case ended on December 15, 2025 — just 133 days after filing — when WebSock filed a Notice of Voluntary Dismissal With Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Judge Gilstrap accepted and acknowledged the dismissal, denied all remaining claims as moot, and ordered each party to bear its own litigation costs. A dismissal with prejudice is a final adjudication on the merits in the plaintiff’s favour of the defendant: WebSock cannot re-assert the same patent claims against NAVER for the same accused products in any future action.
The 133-day lifespan — resolved before any substantive court rulings — is consistent with a pre-litigation settlement or licensing resolution, though the public record is silent on any financial terms. The absence of defendant counsel on record and the speed of resolution suggests NAVER may have engaged directly or through counsel not formally entered in the docket. The with-prejudice designation, rather than a simple voluntary dismissal, typically signals a negotiated conclusion rather than a strategic retreat, though this cannot be confirmed from publicly available filings.

Dismissed with prejudice: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): the plaintiff’s unilateral exit — but permanently
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order before the defendant serves an answer or a motion for summary judgment. By filing with prejudice, WebSock voluntarily surrendered its right to re-litigate these claims. The court’s role was ministerial — to accept, acknowledge, and close the docket. No merits ruling was issued; the dismissal itself is the operative legal event.
Rule 41(a)(1)(A)(i) — with prejudiceWith prejudice: WebSock’s claims against NAVER are permanently extinguished
A with-prejudice dismissal operates as a final judgment on the merits against the plaintiff. WebSock Global Strategies cannot re-file suit against NAVER on US7756983B2 for the same accused products or conduct. This is a materially different outcome from a without-prejudice dismissal, which would preserve the option to re-file. The public record does not disclose whether the with-prejudice filing was made in exchange for consideration — the distinction matters commercially but cannot be confirmed from available filings.
Claims permanently barred vs. NAVERNAVER walks away — no liability finding, no injunction, no fee award
NAVER obtained complete resolution without any adverse ruling. No infringement finding, no damages, and no injunction were entered. The court’s order that each party bear its own costs means NAVER cannot recover its legal spend, though the absence of recorded defendant counsel suggests costs may have been minimal or handled separately. The with-prejudice dismissal provides NAVER with a strong res judicata shield against any future action by WebSock on these claims.
No liability — res judicata protection securedEarly exit before answer suggests a negotiated resolution — not a concession
Cases that terminate with prejudice before any defendant filing typically reflect an agreed outcome rather than plaintiff abandonment. For NAVER, this closes a potential real-time communications IP exposure with no public admission of liability. For the broader WebSocket and bi-directional communication technology sector, US7756983B2 remains a live, unchallenged patent — any operating companies in this space should note that the patent’s enforceability was never adjudicated and a further assertion against other defendants remains possible.

Official order — verbatim text
The court’s order is purely ministerial — it accepts the plaintiff’s unilateral Rule 41(a)(1)(A)(i) filing and closes the case. The operative legal consequence is the with-prejudice designation, which extinguishes WebSock’s claims against NAVER as a matter of res judicata. No claim construction, no infringement analysis, and no validity determination was made. The costs order — each party to bear its own — is standard for voluntary dismissals and does not indicate relative litigation strength.
US7756983B2 — Symmetrical Bi-Directional Communication Technology
US7756983B2 (application no. US12/109198) covers symmetrical bi-directional communication — a foundational capability in modern real-time web infrastructure. The patent addresses the technical challenge of enabling full-duplex, persistent connections between clients and servers, a problem that became commercially critical with the growth of real-time messaging, live data feeds, and interactive web applications. The WebSocket protocol, standardised by the IETF in 2011, is the dominant implementation of this capability, making patents in this space strategically significant.
For the technology sector, US7756983B2 represents a potentially broad claim position over infrastructure that is now ubiquitous — from chat applications to financial trading platforms, multiplayer gaming, and collaborative SaaS tools. NAVER’s core products, including LINE messaging and its cloud services, are plausible targets for bi-directional communication claims. The patent’s validity was never tested in this proceeding, which means it carries full statutory presumption of validity and remains a credible enforcement instrument against any company operating WebSocket-dependent services at scale.
Should your team run an FTO against US7756983B2?
Any product team building or scaling real-time communication features — WebSocket connections, server-sent events, persistent duplex streams — should treat US7756983B2 as a priority FTO candidate. This patent was actively asserted against a large technology company in a plaintiff-friendly venue. The case’s rapid with-prejudice conclusion, without any validity challenge on the record, means the patent has not been stress-tested publicly. Companies in messaging, live data, gaming, and collaborative software are particularly exposed.
PatSnap Eureka’s FTO Search Agent can map US7756983B2’s claim scope against your product architecture, identify prior art that could support an IPR petition, and surface related continuations or family members that may present parallel risks. Running an FTO before a demand letter arrives is materially cheaper than litigation in E.D. Tex. — and the Gilstrap docket moves quickly once filed.

What this case signals for the WebSocket and real-time communications IP landscape
A fast, with-prejudice exit in E.D. Tex. rarely signals weakness — it more often signals a deal. Here is what that means for the sector.
US7756983B2 remains enforceable — further assertions are plausible
Because the case ended without any invalidity ruling, IPR petition, or claim construction order, US7756983B2 retains its full presumption of validity. Any company deploying WebSocket or real-time bi-directional communication technology at scale should treat this patent as an active enforcement risk. The absence of a merits decision means there is no public precedent to rely on as a defence.
E.D. Tex. + Judge Gilstrap: venue choice signals serious enforcement intent
Filing before Judge Gilstrap in the Eastern District of Texas is a deliberate strategic choice. Gilstrap’s docket carries high credibility with patent plaintiffs and is well-known for efficient case management. Even cases that settle quickly reflect a credible threat — defendants in this venue rarely ignore the docket. Any future targets of WebSock assertions in this court should expect a well-resourced plaintiff strategy.
WebSock v NAVER — key questions answered
A dismissal with prejudice under Rule 41(a)(1)(A)(i) operates as a final judgment on the merits against the plaintiff. WebSock Global Strategies cannot re-file the same patent infringement claims against NAVER Corporation based on US7756983B2 for the same accused conduct. NAVER is protected by res judicata. No infringement finding, damages award, or invalidity ruling was made — the dismissal itself is the final legal event.
No. The case terminated before any substantive ruling. US7756983B2 was never subjected to claim construction, an invalidity determination, or an IPR petition in this proceeding. The patent retains its full statutory presumption of validity under 35 U.S.C. § 282 and remains enforceable against other parties.
The public record does not explain the choice. However, a with-prejudice voluntary dismissal filed before any defendant filing is strongly consistent with a negotiated resolution — such as a licence, covenant not to sue, or settlement payment — in exchange for the permanent relinquishment of claims. A without-prejudice dismissal would have preserved the right to re-file, which is a more common outcome in pure strategic retreats.
Judge Gilstrap in the Eastern District of Texas is one of the most experienced patent trial judges in the United States by caseload. The venue is well-regarded by patent plaintiffs for efficient scheduling and jury-friendly outcomes. Choosing this venue, even for a case that resolves quickly, signals that the plaintiff was prepared for substantive litigation and had assessed the claims as commercially viable. Defendants in this venue face structured timelines that incentivise early resolution.
The with-prejudice dismissal protects NAVER only from future actions by WebSock Global Strategies asserting US7756983B2 for the same accused conduct. It does not protect NAVER from assertions by other patent holders covering related WebSocket or bi-directional communication technology. Given that the underlying patent was never adjudicated, NAVER — and other companies in the real-time communications space — should monitor the US7756983B2 ownership and assignment record for potential future enforcement activity.
