Linfo IP v. G2.com: Infringement Suit Over Text-Based Information Discovery Patent
Linfo IP, LLC asserted US9092428B1 — a patent covering systems and methods for discovering and presenting information in text content — against software review platform G2.com, Inc. in the Western District of Texas. The case closed after just 112 days when Linfo voluntarily dismissed its claims without prejudice before G2.com filed any responsive pleading.
Early voluntary exit before G2.com entered a formal defence
On February 16, 2024, Linfo IP, LLC — a patent assertion entity represented by Ramey LLP — filed an infringement action against G2.com, Inc. in the Western District of Texas (Case No. 7:24-cv-00049). The sole patent asserted was US9092428B1, which covers systems, methods, and user interfaces for discovering and presenting information in text content, an area directly relevant to G2.com’s software review and data platform business.
On June 7, 2024 — just 112 days after filing — Linfo IP filed a Notice of Voluntary Dismissal Without Prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because G2.com had not yet served an answer or a motion for summary judgment, the dismissal was self-effectuating: it required no court order and terminated the case immediately. The court subsequently directed the clerk to close the action and ordered each party to bear its own costs and fees.
The timing of the dismissal — before any substantive litigation activity by the defendant — is consistent with patterns seen in patent assertion campaigns where early resolution or strategic withdrawal occurs following initial demand-phase discussions. The public record does not disclose whether a settlement or licensing agreement was reached; the without-prejudice posture means Linfo IP retains the right to refile the same claims against G2.com in future, a factor that may carry strategic significance for G2.com’s IP planning.
Filing to Voluntary dismissal in 112 days
112 days — resolved before any answer or summary judgment motion was filed
Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): a self-effectuating dismissal right
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order simply by filing a notice of dismissal — but only before the opposing party serves an answer or a motion for summary judgment. Because G2.com had not yet done either, Linfo IP’s notice was immediately effective. No judicial approval was required, and the court’s order merely confirmed closure and allocated costs.
No merits adjudicationWithout prejudice — but what does the public record actually say?
The verdict text explicitly states ‘without prejudice,’ meaning Linfo IP is not barred from refiling the same patent claims against G2.com in the future. A without-prejudice dismissal is substantively different from one with prejudice, which would function as a final judgment on the merits. Here, the door remains open for Linfo IP to reassert US9092428B1, whether following a licensing negotiation breakdown or a revised litigation strategy.
Refiling remains possibleG2.com avoids a ruling — but faces lingering exposure
G2.com escapes this particular action without incurring litigation costs beyond early-stage legal fees, and each party bears its own expenses per the court order. However, the without-prejudice dismissal provides no formal patent invalidity ruling and no res judicata shield. G2.com should treat US9092428B1 as an active enforcement risk and consider whether to pursue declaratory judgment, IPR, or design-around strategies proactively.
No invalidity shield obtainedUS9092428B1 remains enforceable — sector risk persists
The absence of any merits ruling leaves US9092428B1 fully intact and enforceable. For companies operating text-based content discovery, software review, or B2B data intelligence platforms, this patent may warrant monitoring. Linfo IP’s use of Ramey LLP — a firm with a well-documented history of patent assertion in Texas — suggests this campaign may extend to other targets in the same technology space.

Official order — verbatim text
The court’s order confirms that Linfo IP’s dismissal was self-effectuating under Rule 41(a)(1)(A)(i), requiring no judicial merits review. The explicit ‘without prejudice’ designation is significant: it preserves Linfo IP’s right to refile identical claims, meaning US9092428B1 has not been adjudicated invalid or non-infringed. For G2.com, the absence of an answer or summary judgment motion means no claim construction, no invalidity arguments, and no estoppel defences were placed on the record.
US9092428B1 — System and methods for discovering and presenting information in text
US9092428B1 covers systems, methods, and user interfaces for discovering and presenting information embedded within text content. The application number US13/709827 suggests a filing origin in the early 2010s, a period of significant innovation in natural language processing, structured data extraction, and contextual information surfaces. The patent’s claims are relevant to any platform that programmatically identifies, structures, and presents information derived from user-generated or curated textual data.
For B2B software intelligence platforms like G2.com — which aggregate, analyse, and present structured information from text-based user reviews — the claims of US9092428B1 could plausibly map onto core product functionality. The patent’s survival without any invalidity challenge in this case means it retains full presumption of validity under 35 U.S.C. § 282. Competitors in the software review, content intelligence, and knowledge management sectors should conduct claim mapping to assess whether their text-processing pipelines fall within the patent’s scope.
Should your product team run an FTO against US9092428B1?
Any company whose product discovers, structures, or presents information extracted from text content — including software review platforms, knowledge bases, content recommendation engines, or NLP-powered data products — should assess freedom to operate against US9092428B1. The patent remains fully enforced and unchallenged. The plaintiff’s without-prejudice exit signals ongoing enforcement intent, and Ramey LLP’s track record suggests additional defendants may follow.
PatSnap Eureka’s FTO Search Agent can map US9092428B1’s claims against your product architecture in hours rather than weeks.

What this case signals for the software information discovery IP landscape
An early Rule 41 exit with no answer filed typically signals one of two things: a licensing deal was struck, or the plaintiff reassessed the litigation path.
Pre-answer dismissals rarely mean the threat is gone
When a plaintiff in a patent assertion campaign dismisses without prejudice before the defendant files an answer, it often indicates behind-the-scenes resolution or a tactical reassessment. US9092428B1 remains valid and enforceable. Competitors of G2.com operating in the text-based discovery and software intelligence space should treat this as a canary, not a clearance.
Each-party-bears-own-costs: no deterrence signal here
The court’s cost allocation order — each party bears its own fees — is standard for a self-effectuating Rule 41 dismissal and carries no exceptional-case or fee-shifting significance under 35 U.S.C. § 285. It does not indicate that either party’s position was found unreasonable. This cost structure is consistent with a negotiated early exit rather than a litigated outcome.
Linfo v G2.com — key questions answered
Linfo IP, LLC sued G2.com, Inc. in the Western District of Texas asserting US9092428B1. After 112 days, Linfo IP filed a voluntary dismissal without prejudice under Rule 41(a)(1)(A)(i) before G2.com served any answer. The court closed the case and ordered each party to bear its own costs.
A without-prejudice dismissal means the case ended without any merits ruling. G2.com obtained no invalidity finding and no non-infringement determination. Linfo IP retains the legal right to refile the same claims based on US9092428B1 against G2.com at a later date, meaning the patent risk has not been extinguished.
US9092428B1 covers systems, methods, and user interfaces for discovering and presenting information in text content. The patent is relevant to platforms that extract, structure, and display information derived from textual data — which could include software review aggregators, content intelligence tools, and NLP-powered data platforms.
The public record does not disclose the reason. Possible explanations include a private licensing agreement, a decision to refocus enforcement efforts, or a reassessment of claim mapping against G2.com’s specific product. The without-prejudice designation preserves all of Linfo IP’s future enforcement options against this defendant.
Yes. Because the case was dismissed without any merits adjudication, US9092428B1 retains its full presumption of validity under 35 U.S.C. § 282. No invalidity arguments were litigated and no IPR petition appears to have been filed in connection with this action. The patent poses an ongoing enforcement risk to companies in the text discovery and software intelligence sector.
