Linfo IP v. Staples: Infringement Action Dismissed With Prejudice in 147 Days
Linfo IP, LLC asserted US9092428B1 — a patent covering systems and methods for discovering and presenting information in text content — against retail giant Staples, Inc. in the Eastern District of Texas. The plaintiff voluntarily dismissed the case with prejudice after just 147 days, closing all claims permanently.
Linfo IP’s Text-Discovery Patent Claim Against Staples Ends Permanently
On December 29, 2023, Linfo IP, LLC filed an infringement action against Staples, Inc. in the United States District Court for the Eastern District of Texas (Case No. 2:23-cv-00636). The asserted patent, US9092428B1, covers a system, methods, and user interface for discovering and presenting information embedded in text content — a technology area relevant to e-commerce search, product recommendation, and content navigation platforms of the kind Staples operates at scale.
The case concluded on May 24, 2024, when Linfo IP filed a Notice of Voluntary Dismissal with prejudice. The Court accepted and acknowledged the notice pursuant to Rule 41(a)(1)(A)(i), formally dismissing all pending claims and causes of action with prejudice and denying all remaining relief requests as moot. A dismissal with prejudice is a final adjudication on the merits as a matter of law — Linfo IP is permanently barred from reasserting the same patent claims against Staples arising from the same conduct.
The 147-day lifespan of the case is notably short and suggests the matter resolved — or was strategically abandoned — before substantive motion practice or claim construction. The public record does not disclose whether a settlement was reached, a license granted, or the claims were simply dropped. The with-prejudice designation is significant: it goes beyond a standard voluntary dismissal and forecloses any future enforcement attempt by Linfo IP against Staples on these specific claims.

Dismissed with prejudice: what the voluntary termination means for both parties
Rule 41 dismissal with prejudice bars all future claims
Under Rule 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss a case before the defendant serves an answer or motion for summary judgment. When the notice specifies ‘with prejudice,’ the dismissal operates as a final adjudication on the merits. Linfo IP’s notice explicitly designated with-prejudice terms, meaning the Court’s acceptance permanently extinguishes the asserted claims against Staples arising from the same conduct.
Rule 41(a)(1)(A)(i) — permanent barLinfo IP permanently forfeits enforcement against Staples
By filing a with-prejudice dismissal, Linfo IP surrendered its right to reassert US9092428B1 against Staples for the accused conduct. The patent itself remains in force and enforceable against other defendants, but this specific litigation avenue is closed. The decision to dismiss with prejudice — rather than without prejudice — may reflect a negotiated resolution, a licensing outcome, or a litigation-risk calculus that the public record does not disclose.
Patent survives — Staples enforcement closedStaples receives permanent protection from this claim
Staples, Inc. obtains the strongest possible resolution short of a court judgment in its favour. The with-prejudice dismissal functions as a permanent shield against Linfo IP reasserting the same patent claims based on the same accused products or conduct. Staples’ legal team, represented by Gillam & Smith LLP, secured this outcome without the cost and uncertainty of full merits litigation or trial.
Full claim bar — no re-litigation riskUS9092428B1 remains a live risk for other text-discovery platforms
Although Linfo IP cannot re-sue Staples, US9092428B1 continues to cover systems and methods for discovering and presenting information in text content. Other e-commerce platforms, SaaS content tools, and retail technology vendors offering similar text-navigation or information-surfacing functionality face potential exposure. The rapid resolution of this case provides no claim construction guidance, leaving the patent’s scope undefined and enforcement risk elevated for the broader sector.

Official order — verbatim text
The Court’s order accepted Linfo IP’s Rule 41(a)(1)(A)(i) notice and entered a with-prejudice dismissal — the strongest form of voluntary termination available. Because the notice was filed before Staples served an answer, no court consent was required. The operative effect is a final disposition on the merits as a matter of law: Linfo IP is permanently barred from reasserting these claims against Staples. The denial of all pending relief requests as moot confirms no substantive ruling was issued on infringement or validity.
US9092428B1 — System and methods for discovering and presenting information in text content
US9092428B1, filed under application number US13/709827, protects a system, methods, and user interface directed at discovering and presenting information embedded within text content. This technology domain encompasses automated identification, surfacing, and navigation of contextually relevant data within written material — capabilities foundational to e-commerce product pages, knowledge management platforms, and content-rich retail environments. The patent’s grant as a utility patent with a B1 designation indicates it issued without a pre-grant publication, suggesting a relatively streamlined prosecution history.
For the retail technology and e-commerce sector, US9092428B1 represents a potentially broad claim set over how digital platforms surface and present information derived from text. Staples, as a major e-commerce operator, plausibly operates search, recommendation, or content-navigation systems that could be characterised as falling within the patent’s claims. The absence of any claim construction ruling means the patent’s true scope — and thus the risk it poses to competing platforms — remains judicially undefined, making it a continued watch-list item for any company deploying text-analysis or content-discovery features.
Should your platform run an FTO against US9092428B1?
Any company operating systems that automatically discover, categorise, or present information derived from text content should assess exposure to US9092428B1. This includes e-commerce search and recommendation engines, SaaS content platforms, knowledge management tools, and retail technology vendors offering text-based product navigation. The patent has not been construed by any court, meaning its claims carry maximum interpretive breadth and represent an elevated litigation risk for product and engineering teams.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map the claims of US9092428B1 against product feature sets in minutes, identify related continuations or family members that may extend the risk perimeter, and surface prior art that could support an invalidity position. Running a structured FTO before deploying new text-discovery or content-surfacing features is the most cost-effective way to manage this exposure before litigation becomes the conversation.

What this case signals for the text-discovery and e-commerce IP landscape
A swift with-prejudice exit in E.D. Texas raises questions about patent scope, licensing dynamics, and NPE enforcement strategy in the content-discovery technology space.
Early voluntary dismissal with prejudice often signals a licensing resolution
When a plaintiff dismisses with prejudice within 147 days — before any substantive ruling — it typically suggests either a confidential license was executed or the plaintiff assessed litigation risk as unfavourable. Either way, the outcome closes the claim permanently and avoids any adverse claim-construction precedent that could weaken the patent for future assertions.
E.D. Texas remains a preferred NPE venue despite accelerated resolutions
Linfo IP’s choice of the Eastern District of Texas is consistent with NPE enforcement strategy: favourable procedural rules and an experienced patent docket. The rapid closure here — 147 days — suggests defendant counsel at Gillam & Smith LLP applied early pressure, potentially through invalidity or non-infringement positions that accelerated plaintiff’s decision to dismiss.
Linfo v Staples — key questions answered
A with-prejudice dismissal under Rule 41 operates as a final adjudication on the merits. Linfo IP is permanently barred from reasserting US9092428B1 claims against Staples arising from the same accused conduct. However, the patent remains enforceable against all other parties, and no claim construction ruling was issued, leaving its scope legally undefined.
US9092428B1 covers a system, methods, and user interface for discovering and presenting information in text content. This broadly encompasses automated identification and surfacing of relevant information within written material — applicable to e-commerce search, content navigation, and text-analysis platforms. The application number is US13/709827.
The public record does not disclose the reason for the 147-day voluntary dismissal. Rapid with-prejudice dismissals before any substantive ruling typically suggest a confidential licensing agreement, a settlement payment, or a plaintiff assessment that the litigation risk outweighed the enforcement potential. No court ruling on infringement or validity was issued.
No. A voluntary dismissal does not constitute a ruling on validity or enforceability. US9092428B1 remains a granted, enforceable patent. The dismissal solely resolves Linfo IP’s claims against Staples. Other companies operating text-discovery or content-surfacing systems should treat the patent as a continuing risk and consider an FTO analysis.
