Linfo IP v. Lorex: Infringement Suit Dismissed With Prejudice After 497 Days
Linfo IP, LLC asserted US9092428B1 — covering systems and methods for discovering and presenting information in text content — against Lorex Corporation in the Western District of Texas. The parties jointly stipulated dismissal under Rule 41(a)(1)(A)(ii): plaintiff’s claims dismissed with prejudice, defendant’s counterclaims dismissed without prejudice, each side bearing its own costs.
Joint Stipulation Ends Text-Discovery Patent Suit on Split Terms
On June 12, 2023, Linfo IP, LLC filed suit against Lorex Corporation in the Western District of Texas (Waco Division) before Judge Alan D. Albright, asserting infringement of US9092428B1. The patent, filed under application number US13/709827, protects a system, methods, and user interface for discovering and presenting information embedded in text content — a technology area relevant to data extraction, smart-device interfaces, and connected-camera ecosystems of the type Lorex operates in.
The case closed on October 21, 2024, via a joint stipulation of dismissal executed under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The stipulation carried asymmetric terms: all of Linfo IP’s claims against Lorex were dismissed with prejudice as to the asserted patent, permanently extinguishing Linfo’s right to refile those specific claims. Lorex’s counterclaims, however, were dismissed without prejudice — leaving Lorex the option to revive those claims in a future proceeding if circumstances warranted.
The 497-day duration before resolution suggests the parties conducted meaningful discovery or claim-construction activity before reaching terms — a timeline consistent with a negotiated resolution rather than an early capitulation. The mutual cost-bearing arrangement, which is standard in negotiated patent exits, leaves the financial terms of any underlying settlement — if one exists — undisclosed on the public record. What drove Linfo IP to accept a with-prejudice bar, while Lorex preserved its counterclaims, is not apparent from the docket alone and may reflect licensing terms, validity concerns, or a broader commercial arrangement.

Rule 41 joint stipulation: what the split dismissal means for each party
Rule 41(a)(1)(A)(ii) joint stipulation explained
A Rule 41(a)(1)(A)(ii) dismissal requires a signed stipulation from all parties who have appeared. Unlike a unilateral voluntary dismissal, both sides must agree. Here, the parties negotiated asymmetric terms: plaintiff’s claims exit with prejudice (final, no refiling on this patent), while defendant’s counterclaims exit without prejudice (revivable). This structure is commonly associated with a negotiated resolution, though the financial terms remain private.
Fed. R. Civ. P. 41(a)(1)(A)(ii)Linfo IP accepts a permanent bar on this patent claim
Dismissal with prejudice as to the asserted patent is a significant concession by Linfo IP. The company cannot refile infringement claims against Lorex under US9092428B1. This outcome suggests either a licensing arrangement was reached, validity risks made continued litigation unattractive, or commercial pressure outweighed the expected recovery. The public record does not confirm which factor was determinative.
Claims permanently barredLorex preserves counterclaims — a notable asymmetry
Lorex’s counterclaims — which may have included invalidity or unenforceability arguments — were dismissed without prejudice, meaning Lorex retains the theoretical option to revive them. Preserving counterclaims while securing a with-prejudice dismissal of plaintiff’s claims is a strong defensive posture. It suggests Lorex negotiated from a position of relative strength, or that the parties agreed this structure as part of a broader commercial settlement.
Counterclaims preservedEach party bears its own costs — standard but significant
The agreement that each party bears its own costs, expenses, and attorneys’ fees removes the risk of a fee-shifting motion under 35 U.S.C. § 285. For Lorex, this avoids the burden of proving the case ‘exceptional’; for Linfo IP, it avoids a potentially adverse fee award. The mutual cost-bearing structure is consistent with a negotiated exit and does not signal judicial findings on the merits of either side’s position.

Official order — verbatim text
The stipulation’s asymmetric structure is the operative detail: Linfo IP’s claims exit with prejudice — a final adjudication on the right to assert this patent against Lorex — while Lorex’s counterclaims are dismissed without prejudice, preserving optionality. No merits determination was made by the court; Judge Albright’s role was ministerial. The cost-neutrality clause forecloses any § 285 exceptional-case motion. The phrasing ‘as to the asserted patent’ in the with-prejudice clause may be significant — it arguably limits the bar to US9092428B1 specifically, potentially leaving related family patents available for future assertion.
US9092428B1 — System and Methods for Discovering Information in Text Content
US9092428B1, filed under application number US13/709827, protects a system, methods, and user interface for discovering and presenting information embedded within text content. The patent sits at the intersection of natural language processing, user interface design, and information retrieval — a domain with broad applicability across consumer electronics, smart-device operating systems, and connected-camera platforms that display text-based alerts, metadata, or event descriptions to end users.
The assertion against Lorex — a security camera and surveillance hardware company — suggests the patent holder viewed Lorex’s device software or companion application as embodying the claimed text-discovery functionality. For companies operating in smart-home, IoT, or connected-security ecosystems, this patent represents a risk vector in any product that surfaces textual information through a structured UI. Related continuation or divisional applications in the same family may extend the assertion risk beyond this single grant.
Should your product team run an FTO against US9092428B1?
If your product — whether a connected camera, IoT device, smart-home hub, or any application that discovers and presents text-embedded information — includes a UI layer for surfacing contextual data from text, US9092428B1 is a relevant clearance target. The with-prejudice dismissal only bars Linfo IP from suing Lorex under this patent; other defendants remain fully exposed. Any company in the surveillance tech, natural language processing, or connected-device UI space should treat this patent as an active FTO concern.

What this case signals for the text-intelligence and smart-device IP landscape
Linfo IP’s acceptance of a with-prejudice bar — while Lorex walks away with counterclaims intact — carries meaningful signals for patent holders and product companies in the connected-device space.
W.D. Tex. NPE suits don’t always end at the plaintiff’s terms
Despite the Western District of Texas being a plaintiff-friendly venue, Linfo IP accepted a with-prejudice dismissal. Companies defending NPE suits in Waco should note that aggressive counterclaim strategies — including invalidity challenges — can shift negotiating leverage even before trial.
Text-processing patents remain active assertion tools for PAEs
US9092428B1 covers systems for discovering and presenting information in text content — a broad functional claim space that touches connected cameras, smart-home UIs, and data-extraction tools. Product companies in these adjacencies should monitor continuation and family patents that Linfo IP or related entities may hold.
Linfo v Lorex — key questions answered
The case was dismissed with prejudice as to Linfo IP’s claims under a joint stipulation filed pursuant to Fed. R. Civ. P. 41(a)(1)(A)(ii). Lorex’s counterclaims were dismissed without prejudice. Each party agreed to bear its own costs, expenses, and attorneys’ fees. No merits ruling was issued by the court.
Dismissal with prejudice as to the asserted patent means Linfo IP is permanently barred from reasserting infringement claims against Lorex under US9092428B1. However, the bar is specific to Lorex — Linfo IP retains the ability to assert the patent against other defendants, and may hold related family patents that are not subject to the same bar.
The joint stipulation expressly preserved Lorex’s counterclaims by dismissing them without prejudice — meaning Lorex retains the theoretical right to revive those claims in a future proceeding. This asymmetric structure suggests Lorex negotiated from a position of strength, potentially using invalidity or unenforceability counterclaims as leverage to secure the with-prejudice dismissal of Linfo IP’s claims.
US9092428B1 is a US patent filed under application number US13/709827. It covers a system, methods, and user interface for discovering and presenting information in text content.
