Linfo IP v. Sally Beauty Holdings: Patent Infringement Action Dismissed With Prejudice
Linfo IP, LLC filed suit against Sally Beauty Holdings in the Western District of Texas asserting US9092428B1, a patent covering systems and methods for discovering and presenting information in text content. After 672 days of litigation, the parties jointly stipulated to dismiss all of Linfo’s claims with prejudice, with each side bearing its own costs and fees.
A text-discovery patent assertion ends in a final, bilateral dismissal
On 19 December 2022, Linfo IP, LLC — a patent-holding entity represented by Ramey LLP — filed an infringement action against Sally Beauty Holdings, Inc. in the Western District of Texas before Judge Alan D. Albright. The sole patent asserted was US9092428B1, directed at systems, methods and user interfaces for discovering and presenting information embedded in text content. Sally Beauty, a major specialty retailer of professional beauty supplies, was defended by Fish & Richardson PC and Latham & Watkins LLP.
The case concluded on 21 October 2024 when the parties filed a joint stipulation of dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Critically, the stipulation is asymmetric: all of Linfo IP’s affirmative claims are dismissed with prejudice — permanently extinguishing any future infringement suit on US9092428B1 against Sally Beauty on the same claims — while Sally Beauty’s counterclaims are dismissed without prejudice, leaving the defendant free to reassert them if circumstances change.
The 672-day duration and the with-prejudice/without-prejudice asymmetry together suggest the resolution may reflect negotiated terms rather than a straightforward capitulation by either side; the public record does not disclose whether any monetary exchange accompanied the stipulation. The equal-costs provision indicates neither party secured fee-shifting, consistent with a privately negotiated resolution. What drove Linfo IP to accept a with-prejudice dismissal — whether claim-construction risk, IPR exposure, or a confidential settlement — remains unknown from the public record.

With-prejudice dismissal: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii): consent dismissal, no court order required
A dismissal under Fed. R. Civ. P. 41(a)(1)(A)(ii) is filed by joint stipulation of all appearing parties — no judicial approval is needed. The with-prejudice designation on Linfo’s claims converts what would otherwise be a procedural exit into a final adjudication on the merits, permanently barring re-litigation of those claims against Sally Beauty on this patent.
Voluntary — binding by agreementLinfo IP permanently surrenders its infringement claims on US9092428B1
By agreeing to a with-prejudice dismissal, Linfo IP cannot reassert the same infringement claims under US9092428B1 against Sally Beauty in any U.S. court. This is the functional equivalent of a final judgment against the plaintiff on those claims, even though no merits ruling was issued. The patent itself remains in force against third parties; only this defendant is shielded.
Claims extinguished vs. Sally BeautySally Beauty’s counterclaims survive — dismissed without prejudice
Sally Beauty’s counterclaims — which in patent cases typically include invalidity and non-infringement declarations — were dismissed without prejudice. This preserves Sally Beauty’s right to revive those counterclaims if Linfo IP were to sue again on related patents or in a different context. The asymmetry is negotiated leverage: Sally Beauty retains optionality while securing full protection from these specific claims.
Counterclaims preservedUS9092428B1 remains a live threat for other text-discovery platform operators
The with-prejudice dismissal shields only Sally Beauty. Any other company operating systems that discover and present information in text content — including e-commerce search, content recommendation, or in-app text analytics — remains potentially exposed to this patent. The lack of a published merits ruling means no claim construction or invalidity determination entered the public record that a third party could invoke as persuasive precedent.

Official order — verbatim text
The joint stipulation is carefully asymmetric: Linfo IP’s affirmative infringement claims are extinguished with prejudice — carrying the legal force of a final judgment — while Sally Beauty’s counterclaims exit without prejudice, preserving defendant optionality. The Rule 41(a)(1)(A)(ii) mechanism requires no judicial merits determination, meaning no claim construction, invalidity finding, or non-infringement ruling entered the record. This limits the precedential value of the dismissal for third parties facing the same patent.
US9092428B1 — System and Methods for Discovering Information in Text Content
US9092428B1, filed under application number US13/709827, protects systems and methods — including a user interface layer — for discovering and presenting information found within text content. The patent sits at the intersection of information retrieval, natural language processing, and UI design. Its claims are directed at the functional pipeline from text ingestion through to surfaced, user-facing information presentation, a scope that potentially covers a broad range of digital commerce and content platforms.
Strategically, a patent of this breadth in the text-discovery domain carries meaningful risk for any company operating search, recommendation, or content-enrichment features within a retail or e-commerce context. Sally Beauty’s use of digital commerce platforms — including product search and description presentation — placed it squarely in scope for this assertion. The absence of any published claim construction ruling means the patent’s boundaries remain untested by a court, sustaining uncertainty for third parties in the sector.
Should your product team run an FTO analysis against US9092428B1?
Any company operating a digital platform that ingests text content and surfaces structured information to end users should treat US9092428B1 as a live FTO concern. This includes e-commerce search engines, in-app product discovery tools, content recommendation systems, and conversational commerce interfaces that parse and present text-derived data. The with-prejudice dismissal here protects only Sally Beauty — it creates no invalidity shield for other potential defendants.
PatSnap Eureka’s FTO Search Agent can map US9092428B1’s independent claims against your product architecture, identify prior art that could support an IPR petition, and flag related patents in the same family or from the same assignee. Running this analysis before a demand letter arrives is materially cheaper than responding to litigation in W.D. Tex., where Judge Albright’s docket has historically moved at above-average pace.

What this case signals for the text-discovery and e-commerce IP landscape
Asymmetric dismissal terms and no fee-shifting together suggest a negotiated resolution with undisclosed commercial terms.
With-prejudice exits by NPEs signal either settlement value or litigation risk management
When a patent assertion entity agrees to dismiss with prejudice, it typically signals one of two things: a confidential monetary settlement, or an assessment that continued litigation posed unacceptable downside risk — such as an adverse claim construction or a pending IPR petition. Neither scenario is confirmed here, but practitioners should note the pattern.
No fee-shifting means no exceptional-case finding — a clean exit for both sides
The equal-costs provision forecloses any § 285 exceptional-case analysis. For Sally Beauty, this avoids the reputational and precedential risk of an exceptional-case ruling. For Linfo IP, it avoids a fee award that could have dwarfed any litigation recovery. This type of clean exit is increasingly common in NPE settlements in the Western District of Texas.
Linfo v Sally — key questions answered
The with-prejudice dismissal extinguishes Linfo IP’s specific infringement claims against Sally Beauty under US9092428B1. The patent itself remains valid and enforceable against all other parties — only Sally Beauty gains permanent protection from these particular claims. No merits ruling was issued, so the patent’s validity and claim scope remain judicially untested.
This asymmetry is a common negotiated outcome in patent settlements. The defendant retains the right to reassert invalidity or non-infringement counterclaims if the patent is asserted again in a related context, while the plaintiff permanently surrenders its offensive claims. It reflects a balance of interests: the plaintiff achieves closure, and the defendant preserves legal optionality at no cost.
The mutual cost-bearing agreement forecloses any claim for attorneys’ fees under 35 U.S.C. § 285, which requires a finding that the case is ‘exceptional.’ By contractually agreeing each party bears its own costs, the parties effectively waive any fee-shifting claim. This is a clean exit that avoids the reputational and financial risk of an exceptional-case motion for both sides.
US9092428B1 covers systems, methods, and user interfaces for discovering and presenting information contained in text content. Products potentially in scope include e-commerce product search engines, in-app text analytics tools, content recommendation engines, and any platform that parses user-facing text to surface structured information. The patent’s claim scope has not been construed by any court, sustaining FTO uncertainty for third parties.
The public record — specifically the joint stipulation filed under Rule 41(a)(1)(A)(ii) — does not disclose any monetary terms. The equal-costs provision confirms no fee award was made, but whether a confidential license fee or lump-sum payment accompanied the dismissal is unknown. The with-prejudice nature of Linfo’s dismissal is consistent with either a paid settlement or a strategic decision to exit based on litigation risk.
