Linfo IP v. AEMBR: Candle Patent Suit Dismissed Without Prejudice in 20 Days
Linfo IP, LLC filed an infringement action against AEMBR Company in the Texas Southern District Court asserting US9092428B1, a patent covering candle technology. The case closed just 20 days after filing via stipulated dismissal without prejudice — one of the shortest lifecycle patent cases on record in this district.
A 20-day candle patent dispute ends before litigation begins
On October 11, 2024, Linfo IP, LLC filed suit against AEMBR Company in the U.S. District Court for the Southern District of Texas, asserting infringement of US9092428B1, a patent relating to candle technology. The case was assigned to Judge Andrew S. Hanen. Linfo IP was represented by William P. Ramey III of Ramey LLP, a firm with a well-documented history of asserting patents in the Texas Southern District. No defendant counsel of record was identified in the public filing.
The case terminated on October 31, 2024 — just 20 days after filing — via a stipulated dismissal without prejudice. A dismissal without prejudice means the claims were not adjudicated on the merits and Linfo IP retains the legal right to refile the same infringement allegations against AEMBR or, potentially, other defendants. No judgment was entered in favor of either party, and no fee or cost award is recorded in the public docket.
The 20-day resolution is notably brief even for early settlement cases, suggesting the parties likely reached a private agreement — possibly a licensing arrangement or covenant not to sue — before substantive litigation commenced. The absence of defendant counsel on record may indicate AEMBR engaged directly or retained counsel outside the docket. The without-prejudice designation leaves enforcement options open for Linfo IP, making this a case worth monitoring for re-assertion activity.

Dismissed without prejudice: what the stipulation means for both parties
Stipulated dismissal without prejudice explained
A stipulated dismissal without prejudice means both parties agreed to terminate the case without a court ruling on the merits. Critically, ‘without prejudice’ preserves Linfo IP’s right to refile the same claims against AEMBR in the future. No judgment, injunction, or finding of infringement or invalidity was issued. This is a procedurally clean exit that avoids any preclusive effect on either side.
No merits adjudicationLinfo IP keeps its enforcement options fully open
Dismissal without prejudice is strategically advantageous for a patent assertion entity. Linfo IP retains US9092428B1 in full force, faces no invalidity finding, and can pursue AEMBR again or target other actors in the candle market. The rapid resolution may reflect a licensing fee collected outside the court record — a common outcome in PAE-driven litigation of this pattern.
Re-assertion risk remainsAEMBR faces no judgment but no permanent protection
AEMBR secured dismissal of the immediate case without any adverse judgment — a near-term win. However, the without-prejudice designation means AEMBR cannot invoke res judicata to block a future refiling. Unless AEMBR obtained a covenant not to sue or a license as part of the settlement, ongoing exposure under US9092428B1 remains. The absence of defendant counsel on the docket suggests the matter may have been resolved through direct negotiation.
No permanent bar to refilingCandle sector patent risk: PAE activity targeting consumer products
This case is consistent with a broader pattern of patent assertion entities filing targeted, fast-moving infringement actions against consumer product companies to extract licensing fees before costly litigation begins. Companies operating in the candle and consumer goods space should assess their exposure to US9092428B1 and monitor Linfo IP’s broader assertion activity. A 20-day lifecycle with no adverse ruling suggests the strategy is commercially effective.

Official order — verbatim text
The stipulation of dismissal without prejudice is the entire dispositive record in this case — no judge made findings of fact or conclusions of law regarding infringement, validity, or claim scope. The phrase ‘without prejudice’ carries significant strategic weight: it explicitly prevents AEMBR from relying on this termination as a bar to future litigation. For practitioners, this outcome offers no precedential guidance on the merits of US9092428B1 and leaves the patent’s enforceability entirely intact.
US9092428B1 — candle technology consumer product patent
US9092428B1 (application number US13/709827) is a U.S. patent held by Linfo IP, LLC covering technology in the candle product space. The patent’s grant-level number and application history suggest it proceeded through standard prosecution before issuance. While the precise claim scope is not detailed in the litigation record, the product identified — candles — places this squarely in the consumer goods sector. The patent’s enforceability has not been adjudicated in this proceeding.
From a competitive intelligence perspective, US9092428B1 represents an assertion risk for any company manufacturing, importing, or retailing candle products in the U.S. market. Patent assertion entities holding consumer product patents frequently assert them against multiple defendants in succession, and a rapid without-prejudice dismissal typically signals a licensing payment rather than a surrender of enforcement rights. Companies in the candle, home fragrance, and wax goods segments should evaluate their product lines against this patent’s claims.
Should you run an FTO analysis against US9092428B1?
Any company designing, manufacturing, or distributing candles or candle-adjacent consumer products in the U.S. should assess its exposure to US9092428B1. The PAE assertion pattern visible in this case — rapid filing, fast resolution, no defense on the merits — is a strong indicator that the patent holder views its claims as broadly applicable. Absence of an invalidity ruling means the patent remains presumptively valid and enforceable.

What this case signals for the consumer products IP landscape
A 20-day lifecycle with no defense counsel on record is a textbook PAE pattern — and a warning signal for consumer goods brands.
Without-prejudice dismissals preserve PAE re-assertion leverage
Linfo IP’s choice to dismiss without prejudice — rather than with prejudice — is deliberate. It preserves the threat of renewed litigation as ongoing leverage. Consumer product companies that settle without securing a covenant not to sue or license may face repeat demands. IP teams should ensure any resolution explicitly forecloses future claims under the asserted patent.
Ramey LLP filing patterns warrant proactive monitoring
William P. Ramey III and Ramey LLP are associated with a high volume of patent assertion filings in the Texas Southern District. Companies in adjacent consumer product categories — home goods, fragrance, lifestyle brands — should monitor this firm’s docket activity as an early-warning indicator of potential assertion campaigns targeting their sector.
Linfo v AEMBR — key questions answered
In Linfo IP v. AEMBR (4:24-cv-03890), dismissal without prejudice means the court made no ruling on infringement or patent validity. Linfo IP voluntarily agreed to drop the case via stipulation but retains the right to refile the same claims under US9092428B1 against AEMBR or other defendants at any future date.
Linfo IP asserted US9092428B1 (application no. US13/709827), a patent covering candle technology. The case identified candles as the accused product category. The patent remains in force following the dismissal without prejudice, as no invalidity or non-infringement finding was issued.
The 20-day resolution — from filing on October 11 to dismissal on October 31, 2024 — suggests the parties reached a private agreement before substantive litigation commenced. No defendant counsel appeared on the docket, which is consistent with a direct licensing payment or negotiated covenant not to sue. The public record does not disclose financial terms.
The public record characterises Linfo IP, LLC as a patent holder with no listed commercial product or address. Its representation by Ramey LLP — a firm with a high volume of patent assertion filings — and the rapid, without-prejudice resolution are consistent with PAE litigation strategy, though the public record does not formally classify Linfo IP as a PAE.
Yes. Because the dismissal was without prejudice, AEMBR received no preclusive protection against future litigation under US9092428B1. Unless AEMBR secured a written covenant not to sue or a paid-up license as part of any private agreement, Linfo IP retains the legal right to refile infringement claims against AEMBR at any time while the patent remains in force.
