Linfo IP v. 4Patriots: Infringement Action Dismissed With Prejudice in 166 Days
Linfo IP, LLC asserted US9092428B1 — covering systems and methods for discovering and presenting information in text content — against 4Patriots, LLC in Georgia’s Northern District. The parties reached a joint stipulation of dismissal with prejudice in under six months, with each side bearing its own costs and attorneys’ fees.
Early joint stipulation ends text-discovery patent dispute before merits ruling
On 9 August 2024, Linfo IP, LLC filed a patent infringement action against 4Patriots, LLC in the United States District Court for the Northern District of Georgia, assigned to Judge Sarah E. Geraghty. The asserted patent, US9092428B1 (application no. US13/709827), covers systems, methods, and a user interface for discovering and presenting information embedded in text content — a technology class relevant to consumer-facing digital platforms and information retrieval products.
On 17 January 2025, the parties filed a joint stipulation of dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Plaintiff Linfo IP’s claims were dismissed with prejudice, meaning it cannot re-file the same infringement action against 4Patriots on these patent claims. Defendant 4Patriots’ counterclaims, by contrast, were dismissed without prejudice, preserving 4Patriots’ ability to revive those counterclaims in future proceedings. Each party agreed to bear its own legal costs and fees.
At 166 days, the case resolved substantially faster than the median patent case in the Northern District of Georgia, suggesting the parties likely negotiated a resolution — potentially a licence, covenant not to sue, or commercial agreement — before significant litigation costs accrued. The asymmetric prejudice terms (plaintiff with, defendant without) are a notable structural feature that may signal negotiating leverage held by 4Patriots. The financial terms, if any, remain undisclosed.

Asymmetric dismissal: what the with/without prejudice split means for both parties
Rule 41(a)(1)(A)(ii) joint stipulation — no court order required
A Rule 41(a)(1)(A)(ii) dismissal is filed by the parties jointly and takes effect without a court order. It is the procedural hallmark of a negotiated resolution: both sides have agreed on terms and chosen to exit cleanly. The fact that this was a joint — not unilateral — stipulation confirms mutual consent, distinguishing it from a plaintiff walking away unilaterally.
Negotiated exit — no merits rulingPlaintiff dismissed with prejudice; Defendant’s counterclaims survive
The asymmetric prejudice terms are legally significant. Linfo IP’s infringement claims are dismissed with prejudice — it cannot re-assert US9092428B1 against 4Patriots in a new action on the same accused conduct. 4Patriots’ counterclaims, dismissed without prejudice, remain available for future litigation. This structure typically reflects a concession by the patent holder in exchange for resolution, and may suggest 4Patriots held stronger leverage during negotiations.
Patent holder barred from refiling4Patriots exits with counterclaim rights intact and no fee award against it
4Patriots secured the dismissal of Linfo IP’s claims with prejudice while retaining the right to pursue its own counterclaims in future proceedings. The fee arrangement — each party bears its own costs — means 4Patriots bore its own defence costs but avoided any adverse cost order. The retention of counterclaim rights without prejudice is consistent with 4Patriots maintaining future optionality, potentially including validity challenges to the asserted patent.
Defendant retains counterclaim optionalitySwift closure before claim construction limits public record on patent scope
Because the case closed before any substantive briefing or claim construction order, there is no judicial interpretation of US9092428B1’s scope on the public record. For companies operating in text-based information discovery or similar content-processing technology, this means the patent’s enforceability and claim boundaries remain untested in court. Third parties cannot rely on this case as a limiting or expanding precedent — independent FTO analysis remains essential.

Official order — verbatim text
The joint stipulation’s explicit differentiation of prejudice terms — with prejudice for plaintiff’s claims, without prejudice for defendant’s counterclaims — is the operative legal distinction. Under Rule 41(a)(1)(A)(ii), this filing requires no judicial approval and carries immediate effect. The with-prejudice designation on Linfo IP’s claims functions as a final adjudication on the merits for preclusion purposes, foreclosing future infringement suits on the same claims against 4Patriots. No court has assessed the validity or scope of US9092428B1.
US9092428B1 — System and methods for discovering information in text content
US9092428B1, filed under application number US13/709827, claims systems, methods, and a user interface for discovering and presenting information found within text content. The patent sits at the intersection of natural language processing, information retrieval, and user interface design — a technical domain that underpins recommendation engines, in-content linking systems, and intelligent content annotation tools. The B1 designation indicates it issued without any post-grant reexamination amendment.
From a competitive intelligence perspective, the patent’s broad framing around ‘discovering and presenting information in text content’ creates potential claim coverage across a wide range of digital consumer products — from e-commerce platforms that surface product information from editorial content to subscription services that enrich text with contextual data. 4Patriots’ business in consumer-facing digital commerce makes it a plausible target for such an assertion, and Linfo IP’s retention of broader enforcement rights means the patent remains strategically active against other market participants.
Should your product team run an FTO check against US9092428B1?
Any company building products that extract, surface, or present structured information from unstructured text content should assess their exposure to US9092428B1. This includes teams developing content-enrichment tools, in-text contextual linking, semantic annotation layers, knowledge graph integrations, or AI-driven content recommendation features. The absence of any claim construction ruling in the 4Patriots case means the patent’s boundaries have not been judicially narrowed — its scope remains as broad as the claims on their face.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against the claim language of US9092428B1, surface relevant prior art that could support an invalidity argument, and identify whether any continuation applications in the same family extend the enforcement risk. Running this analysis proactively — before receiving a demand letter — is materially cheaper than doing so under litigation pressure with a Ramey LLP filing already on file.

What this case signals for the text-discovery and content-processing IP landscape
A fast, asymmetric dismissal with prejudice — before claim construction — is a pattern worth tracking in patent assertion activity.
Early resolution before claim construction is not cost-free for patent holders
Linfo IP accepted a with-prejudice dismissal in under six months, surrendering the right to re-assert these claims against 4Patriots. For companies targeted by similar assertions, this outcome suggests that robust early-stage defence posture — including validity challenges and strong claim construction preparation — can accelerate favourable resolution and shift negotiating dynamics before substantial fees accumulate.
Asymmetric prejudice terms reveal negotiating leverage — read them carefully
When a joint stipulation carries different prejudice terms for each side, the structure itself signals who held stronger leverage. 4Patriots’ counterclaims surviving without prejudice suggests its legal team — Fish & Richardson — built a credible threat posture early. Companies facing infringement assertions should consider the strategic value of filing substantive counterclaims to create this kind of exit-term asymmetry.
Linfo v 4Patriots — key questions answered
Linfo IP’s infringement claims under US9092428B1 against 4Patriots are permanently barred — they cannot be refiled. The with-prejudice designation operates as a final adjudication for res judicata purposes, meaning the same patent claims on the same accused conduct cannot be brought against 4Patriots again. 4Patriots’ counterclaims, however, were dismissed without prejudice and remain available for future proceedings.
Linfo IP asserted US9092428B1, filed under application number US13/709827. The patent covers systems, methods, and a user interface for discovering and presenting information in text content. It issued as a B1 patent, indicating it was published without post-issuance reexamination amendments.
The public record does not disclose settlement terms or the specific reason for early resolution. At 166 days, the case closed before claim construction, which typically suggests the parties negotiated an agreement — potentially a licence, covenant not to sue, or commercial terms — before significant litigation costs were incurred. The asymmetric prejudice terms suggest 4Patriots may have held stronger negotiating leverage.
No. The with-prejudice dismissal binds only 4Patriots and only for the accused conduct in this action. Linfo IP retains full rights to assert US9092428B1 against other defendants. No court has ruled on the patent’s validity or claim scope, so the patent remains as enforceable as before the filing of this case.
4Patriots was represented by Fish & Richardson PC, with attorneys Alexander H. Martin, Lawrence Rodell Jarvis, Neil J. McNabnay, and Ricardo J. Bonilla listed as counsel. Fish & Richardson is one of the leading patent litigation firms in the US, and their involvement is consistent with a defendant mounting a credible early-stage defence that may have contributed to the swift resolution.
