Ravenwhite Licensing v. Walmart: Joint Dismissal Without Prejudice After 354 Days
Ravenwhite Licensing LLC filed suit against Walmart Inc. and Wal-Mart Stores Texas LLC in the Eastern District of Texas, asserting two patents against Walmart’s systems. After nearly a full year of litigation, the parties filed a joint stipulation resolving the matter — with the case dismissed without prejudice under Rule 41(a)(1)(A)(ii).
Licensing entity targets Walmart in E.D. Texas patent dispute
On September 15, 2023, Ravenwhite Licensing LLC filed a patent infringement action against Walmart Inc. and its Texas affiliate Wal-Mart Stores Texas LLC in the Eastern District of Texas (Case No. 2:23-cv-00418). Ravenwhite asserted two patents — US10594823B1 and US11562402B2 — against Walmart’s internal systems, alleging infringement in one of the most plaintiff-friendly federal venues for patent litigation.
The case closed on September 3, 2024, via a Joint Stipulation of Dismissal filed by both parties. Pursuant to Rule 41(a)(1)(A)(ii), the court accepted the stipulation and dismissed all pending claims without prejudice. Crucially, a dismissal without prejudice does not constitute a final adjudication on the merits — Ravenwhite retains the legal right to refile these same patent claims against Walmart, subject to applicable statutes of limitation and procedural constraints.
The 354-day timeline — just under one year — suggests the parties likely reached a resolution, licensing agreement, or strategic understanding prior to any substantive rulings on claim construction or invalidity. The public record does not disclose financial terms or any admission of liability. What drove the resolution, and whether any license was granted, remains confidential, which is consistent with a negotiated outcome between a licensing entity and a major retail defendant.

Dismissed without prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii) dismissal: no merits adjudication
A joint stipulation of dismissal under Rule 41(a)(1)(A)(ii) requires signatures from all parties and takes effect without a court order. The court here formally accepted and acknowledged the stipulation. Critically, ‘without prejudice’ means the court made no ruling on patent validity, infringement, or enforceability — the slate is wiped clean procedurally, but no legal precedent is set.
Procedural exit — no merits rulingRavenwhite retains the right to refile — patents remain unchallenged
Because the dismissal is without prejudice, Ravenwhite Licensing preserves the ability to reassert US10594823B1 and US11562402B2 against Walmart or other defendants in future litigation. Neither patent was invalidated or found unenforceable. This outcome is consistent with a licensing entity securing a confidential resolution while keeping its portfolio intact for further monetisation efforts.
Patents survive — refiling rights preservedWalmart avoids a merits ruling but gains no invalidity shield
Walmart exits this specific proceeding without an infringement finding, but equally without a judgment of invalidity or non-infringement that could be used defensively in future disputes. If Ravenwhite refiles — or if related patents are asserted by other licensing entities — Walmart cannot rely on this dismissal as a prior adjudication. The absence of a merits ruling may signal a negotiated resolution, but offers no long-term legal certainty.
No invalidity shield obtainedActive portfolio: both patents remain enforceable against the sector
US10594823B1 and US11562402B2 remain fully valid and enforceable following this dismissal. Other retailers, e-commerce operators, or technology vendors whose systems may overlap with these patents’ claims face continuing exposure. Ravenwhite’s willingness to litigate in E.D. Texas and resolve within a year is consistent with a systematic licensing strategy, suggesting additional defendants in the sector could follow.

Official order — verbatim text
The court’s order is purely procedural — it accepts the parties’ joint stipulation and applies Rule 41(a)(1)(A)(ii) without any independent assessment of the patent claims or infringement allegations. The phrase ‘has been resolved’ in the stipulation suggests the parties reached a private agreement, though its terms are not part of the public record. The without-prejudice designation is legally significant: it forecloses neither party from future litigation on the same patents, and Walmart receives no issue-preclusion benefit from this outcome.
US10594823B1 & US11562402B2 — technology patents asserted against Walmart systems
US10594823B1 (Application No. US15/706556) and US11562402B2 (Application No. US17/201306) are the two patents Ravenwhite asserted against Walmart’s systems. US11562402B2, with its later application number in the US17 series, is likely a continuation or related filing to the earlier US15 application, suggesting a coordinated patent family strategy. The public record does not disclose the full claim scope or the specific Walmart system functionality alleged to infringe.
For the retail and e-commerce technology sector, the assertion of these patents against one of the world’s largest retailers signals meaningful commercial scope. Licensing entities that target Walmart typically do so only when they believe their claims are sufficiently broad to survive early dispositive challenges. The survival of both patents through a 354-day litigation — without any invalidity finding — means the risk to other operators in this technology space remains active and unresolved.
Should your team run an FTO against US10594823B1 and US11562402B2?
Any company operating retail management systems, digital commerce platforms, or similar backend infrastructure that could resemble ‘Walmart system’ functionality should treat these two patents as active FTO priorities. The without-prejudice dismissal means neither patent has been adjudicated invalid or limited by claim construction — they are fully enforceable at their broadest filed scope. E-commerce operators, omnichannel retailers, and retail technology vendors are all potentially within Ravenwhite’s targeting profile.

What this case signals for the retail technology IP landscape
A licensing entity asserting two patents against Walmart in E.D. Texas, resolved quietly in under a year, carries clear signals for IP teams across retail and e-commerce.
E.D. Texas remains a preferred venue for licensing entity campaigns
Ravenwhite’s choice of the Eastern District of Texas is consistent with its plaintiff-friendly reputation and established patent litigation infrastructure. Retail and e-commerce technology IP teams should treat E.D. Texas filings involving their sector as high-priority monitoring targets — early resolution does not diminish the strategic threat posed by the underlying patents.
Without-prejudice dismissal signals negotiated resolution, not capitulation
The joint nature of this dismissal, combined with the without-prejudice posture, strongly suggests a negotiated outcome — likely a license or covenant not to sue. IP counsel for defendants in similar licensing campaigns should assess whether engaging early in settlement discussions reduces overall exposure compared to pursuing invalidity through IPR or litigation.
Ravenwhite v Walmart — key questions answered
Dismissed without prejudice means the court made no ruling on the merits of Ravenwhite’s patent infringement claims. All claims were terminated via joint stipulation under Rule 41(a)(1)(A)(ii), and Ravenwhite retains the right to refile the same patent claims against Walmart or other defendants in the future.
Ravenwhite asserted two patents: US10594823B1 (Application No. US15/706556) and US11562402B2 (Application No. US17/201306). Both were asserted against Walmart’s systems in the Eastern District of Texas. Neither patent was invalidated or found non-infringing as a result of this case.
The joint stipulation states the case ‘has been resolved,’ which is consistent with a negotiated outcome such as a license or covenant not to sue. However, no settlement terms are disclosed in the public record. The without-prejudice dismissal preserves both parties’ positions and offers no conclusive confirmation of financial terms.
Yes. Both patents remain fully enforceable. The without-prejudice dismissal does not affect their validity or claim scope. No invalidity finding, claim construction order, or non-infringement ruling was issued during the case, meaning Ravenwhite can assert these patents against other defendants without any adverse legal precedent from this proceeding.
The Eastern District of Texas is a historically plaintiff-friendly venue for patent litigation, with established procedural rules, experienced patent judges, and a reputation for permitting cases to proceed to trial. Licensing entities frequently select E.D. Texas to maximise settlement leverage, as defendants face higher litigation costs and uncertainty in this jurisdiction compared to some other federal districts.
