Linfo IP v. JRSK: Infringement Claims Dismissed With Prejudice in 183 Days
Linfo IP, LLC asserted US9092428B1 — a patent covering systems and methods for discovering and presenting information in text content — against JRSK, Inc. in the Western District of Texas. The case closed in 183 days via joint stipulation: plaintiff’s claims dismissed with prejudice, defendant’s counterclaims dismissed without prejudice.
A swift stipulated exit: Linfo IP’s text-discovery patent claim ends at 183 days
On April 22, 2024, Linfo IP, LLC filed suit against JRSK, Inc. in the Western District of Texas (Case No. 7:24-cv-00107), asserting infringement of US9092428B1. That patent, issued under application number US13/709827, covers a system, methods, and user interface for discovering and presenting information within text content — a technology with broad applicability across content platforms and information-retrieval products.
The case closed on October 22, 2024 — exactly 183 days after filing — following a Joint Stipulation of Dismissal filed by both parties on October 21, 2024. Under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), the court confirmed the stipulation was self-executing and required no judicial approval. Plaintiff’s infringement claims were dismissed with prejudice, permanently barring re-assertion of those specific claims against JRSK. Defendant’s counterclaims were dismissed without prejudice, leaving JRSK the option to revive them in future proceedings.
A 183-day resolution is notably fast for patent litigation in the Western District of Texas, suggesting settlement or licensing terms may have been negotiated outside the public record. The asymmetric dismissal structure — plaintiff’s claims with prejudice, defendant’s counterclaims without — is a common hallmark of a negotiated resolution, though the specific commercial terms, if any, are not reflected in the public docket. What drove JRSK’s counterclaims and whether any license was exchanged remain unknown.
Filing to Case Dismissed in 183 days
183 days — resolved well under the median district court patent case duration of ~2.5 years, suggesting early negotiation pressure.
Joint stipulation dissected: what the with-prejudice dismissal means for both sides
Rule 41(a)(1)(A)(ii): self-executing dismissal, no court approval needed
A stipulated dismissal under FRCP 41(a)(1)(A)(ii) takes effect automatically upon filing when signed by all appearing parties. The court’s order here was confirmatory, not substantive — the dismissal was legally effective the moment the joint stipulation was filed on October 21, 2024. This mechanism is frequently used when parties have reached a private resolution and wish to exit litigation cleanly without a public merits ruling.
FRCP 41(a)(1)(A)(ii)With-prejudice dismissal: Linfo IP cannot re-sue JRSK on this patent
Dismissal with prejudice operates as a final adjudication on the merits. Linfo IP is permanently barred from re-asserting US9092428B1 against JRSK, Inc. in any subsequent action. This is the most legally consequential concession a plaintiff can make short of a trial loss. It strongly suggests Linfo IP received some form of consideration — whether a license payment, cross-license, or other commercial arrangement — though the public record is silent on specific terms.
Claims extinguished as to JRSKJRSK’s counterclaims survive: dismissed without prejudice
JRSK’s counterclaims were dismissed without prejudice, meaning they were not resolved on the merits and could theoretically be re-filed. In practice, this is standard in negotiated exits — the defendant preserves optionality (e.g., invalidity claims) while agreeing not to pursue them immediately. The without-prejudice carve-out likely served as a negotiating lever that gave JRSK some protection against future enforcement by Linfo IP or successor entities.
Counterclaims preservedNo fee-shifting: each party absorbs its own litigation costs
The court ordered each party to bear its own attorney fees and costs. In patent cases, fee-shifting under 35 U.S.C. § 285 requires a finding that the case is ‘exceptional’ — that threshold was not reached or not pursued here. Mutual cost absorption is consistent with a negotiated resolution where neither side wanted to escalate to a fees motion. For JRSK, represented by Fish & Richardson, litigation costs were likely significant even over 183 days.

Official order — verbatim text
The court’s order confirms the joint stipulation was self-executing under FRCP 41(a)(1)(A)(ii), requiring no substantive judicial determination. The asymmetric prejudice structure — plaintiff’s claims with prejudice, defendant’s counterclaims without — reflects a negotiated asymmetry rather than a merits adjudication. No claim construction, infringement finding, or validity ruling was issued, meaning US9092428B1 exits this litigation with its claims legally intact and presumptively valid against third parties.
US9092428B1 — System and methods for discovering and presenting information in text
US9092428B1, filed under application number US13/709827, covers a system, methods, and user interface for discovering and presenting information embedded within text content. This class of invention sits at the intersection of natural language processing, content annotation, and information retrieval — technologies central to modern content platforms, knowledge management tools, browser extensions, and AI-assisted reading applications. The patent’s B1 designation indicates it issued without reexamination amendments, and its claims have not been adjudicated in this proceeding.
The strategic significance of US9092428B1 extends to any product that identifies, surfaces, or contextualises entities, concepts, or links within text — from news aggregators and enterprise search tools to AI-powered document analysis platforms. As large-language-model-based interfaces increasingly parse and annotate text at scale, patents covering the underlying discovery-and-presentation layer are gaining renewed enforcement attention. The absence of a merits ruling in this case means the patent’s full claim scope remains untested and represents a live risk for companies in the content-technology sector.
Should you run an FTO analysis against US9092428B1?
Any product or service that identifies, extracts, highlights, or presents contextual information from text content — including browser-based tools, document readers, content management systems, enterprise search platforms, and AI text-analysis applications — should treat US9092428B1 as a live FTO concern. The patent was never invalidated or narrowed in this litigation, and the with-prejudice dismissal applies only to JRSK. Linfo IP retains full enforcement rights against every other party in the market.
PatSnap Eureka’s FTO Search Agent allows R&D and product teams to map the claims of US9092428B1 against your specific product architecture, identify prior art that could support an IPR petition, and monitor assignment or licensing activity around the patent. Given that Ramey LLP typically files in multiple districts sequentially, early claim-mapping can materially reduce your exposure window and inform a pre-suit response strategy before a demand letter arrives.

What this case signals for the text-discovery and content-technology IP landscape
A fast, asymmetric dismissal in the Western District of Texas carries predictable signals for patent assertion strategy in the information-retrieval sector.
With-prejudice exits in PAE cases typically signal a negotiated license
When a patent assertion entity dismisses with prejudice — as Linfo IP did here — it almost never does so without receiving value. The 183-day timeline and absence of any substantive motion practice on the docket suggests the parties reached terms before significant litigation costs accumulated. Companies facing similar assertions from Linfo IP should treat this precedent as evidence that early engagement can produce favorable exit terms.
JRSK’s counterclaims without prejudice preserve a validity challenge option
By keeping its counterclaims alive in form, JRSK retains the ability to challenge US9092428B1’s validity in a future proceeding — including inter partes review — if Linfo IP or an assignee attempts to re-assert the patent against other defendants. Any company currently facing an assertion of US9092428B1 should monitor whether JRSK’s counterclaim strategy provides a roadmap for an IPR petition.
Linfo v JRSK — key questions answered
The with-prejudice dismissal bars Linfo IP from re-suing JRSK on US9092428B1. However, it has no effect on Linfo IP’s ability to enforce the patent against other defendants. The patent’s claims were never adjudicated, so no invalidity or non-infringement ruling arose that could benefit third parties through collateral estoppel.
This asymmetric structure is characteristic of negotiated resolutions. Dismissing defendant’s counterclaims without prejudice preserves JRSK’s ability to revive validity or other challenges if litigation re-ignites. It functions as a protective mechanism for the defendant and is a common term in patent settlement structures where the plaintiff receives value in exchange for the with-prejudice concession.
The dismissal was entered under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), which permits voluntary dismissal by filing a stipulation signed by all parties who have appeared. As confirmed by the Fifth Circuit in Yesh Music v. Lakewood Church, such stipulations are self-executing and take effect automatically upon filing without requiring court approval.
The public record does not confirm a financial settlement. However, a 183-day resolution via joint stipulation with a with-prejudice dismissal of plaintiff’s claims strongly suggests the parties reached a private arrangement — potentially a license, covenant not to sue, or other commercial agreement. The absence of substantive motion practice on the docket is consistent with early negotiated resolution.
US9092428B1 covers a system, methods, and user interface for discovering and presenting information in text content. Products potentially within scope include browser extensions, content annotation tools, enterprise search platforms, AI-assisted document readers, news aggregation services, and any application that surfaces contextual information from text. The patent’s claims remain valid and enforceable against parties other than JRSK.
