Linfo IP v. Summer Moon Franchising: Dismissed With Prejudice in 120 Days
Linfo IP, LLC asserted US9430131B1 against Summer Moon Franchising LLC — a specialty coffee, tea, and baked goods brand — in the Western District of Texas. The plaintiff voluntarily dismissed all claims with prejudice before the defendant had even answered, closing the case in just 120 days with each party bearing its own costs.
A pre-answer exit: Linfo IP drops patent claim with no path to refile
On 21 May 2025, Linfo IP, LLC filed a patent infringement action against Summer Moon Franchising LLC in the Western District of Texas, case no. 7:25-cv-00239. The asserted patent, US9430131B1, was alleged to cover technology relevant to Summer Moon’s specialty coffee, tea, baked goods, and related food and beverage products sold under the SUMMER MOON™ trade name. Plaintiff was represented by William P. Ramey III of Ramey LLP, a firm known for asserting patents in the Western District of Texas.
The case closed on 18 September 2025 — just 120 days after filing — when Linfo IP filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Critically, the plaintiff elected to dismiss with prejudice as to the asserted patent, meaning Linfo IP permanently surrendered its right to bring the same infringement claims against Summer Moon Franchising based on US9430131B1. No defendant answer or motion for summary judgment had been filed, which is the prerequisite for a unilateral Rule 41(a)(1)(A)(i) dismissal.
A voluntary dismissal with prejudice at this early stage — before any substantive litigation — is atypical and suggests either a negotiated resolution (the terms of which would be confidential) or a strategic reassessment by Linfo IP. The with-prejudice election is notable: a plaintiff filing under Rule 41(a)(1)(A)(i) could have dismissed without prejudice to preserve future options. The decision not to do so, combined with a mutual cost-bearing arrangement, is consistent with a quiet settlement or a concession that the patent position against this defendant was untenable.

Dismissed with prejudice: what the voluntary exit means for both parties
Rule 41(a)(1)(A)(i): unilateral dismissal before defendant responds
Federal Rule 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order if the defendant has not yet served an answer or a motion for summary judgment. Linfo IP invoked this rule to exit unilaterally. However, the plaintiff went further by electing dismissal with prejudice — a voluntary concession that permanently bars re-assertion of the same patent claims against this specific defendant. The court need not approve such a dismissal.
Pre-answer voluntary dismissalWith prejudice: Linfo IP permanently closes the door on Summer Moon
A Rule 41(a)(1)(A)(i) dismissal is without prejudice by default — the plaintiff could ordinarily refile and reassert the patent. Here, Linfo IP explicitly chose dismissal with prejudice as to the asserted patent, permanently forfeiting the right to sue Summer Moon Franchising again under US9430131B1. This is a meaningful concession. It signals either a settled dispute with confidential terms, or a plaintiff conclusion that the infringement position against this defendant could not survive scrutiny.
Permanent bar on re-assertionSummer Moon exits with full immunity — and no fee award needed
Summer Moon Franchising LLC achieved a complete resolution without filing a single substantive pleading. The with-prejudice dismissal provides the defendant with permanent protection against future assertion of US9430131B1 by this plaintiff. Although no attorneys’ fees were awarded — each party bears its own costs — the practical outcome is strong: the franchise operator faces no ongoing infringement liability under this patent and incurred minimal disclosed litigation cost.
Full defence without fees motionWhat early dismissal signals for food and beverage patent risk
Patent assertion entities targeting food and beverage or franchise brands in the Western District of Texas sometimes withdraw when defendants signal robust opposition or when licensing negotiations collapse. The speed of this dismissal — 120 days, pre-answer — and the with-prejudice election suggest the case resolved or the plaintiff reassessed viability before incurring major litigation costs. Other food-service and franchise operators holding similar technology should note that asserting US9430131B1 against them by Linfo IP remains legally possible, as the with-prejudice bar applies only to Summer Moon.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i), confirming Summer Moon had not answered or moved for summary judgment — preserving the plaintiff’s unilateral right to exit. The express with-prejudice election as to the asserted patent is the operative language: it converts what would be a default without-prejudice dismissal into a permanent bar. The mutual cost-bearing clause forecloses any subsequent fee motion, suggesting both parties accepted finality in exchange for a clean exit. No merits determination was reached.
US9430131B1 — digital interface or ordering technology for food and beverage
US9430131B1, filed under application number US14/225422, is asserted by Linfo IP, LLC — a patent assertion entity with no apparent commercial product operations. The patent’s grant number and application filing context suggest it covers digital interface, ordering, or information-management technology that Linfo IP contends is practised by operators of food and beverage retail and franchise systems. The ‘B1’ designation indicates this is a granted US utility patent issued without reexamination. Without access to the claim text, the precise technical scope cannot be confirmed from public litigation records alone.
The decision to assert this patent against a specialty coffee and food franchise operator in the Western District of Texas is consistent with broader PAE strategies targeting digital transformation in the food-service and quick-service restaurant sector. Franchise systems that deploy digital ordering, loyalty platforms, or point-of-sale integrations under branded trade names represent a class of defendants where technology patents are increasingly being asserted. The quick dismissal with prejudice in this case suggests the specific infringement theory against Summer Moon may not have been sufficiently robust to withstand early challenge.
Should you run an FTO analysis against US9430131B1?
Any food-service operator, franchise system, or digital ordering platform provider that deploys technology potentially covered by US9430131B1 should treat this case as a trigger for a freedom-to-operate review. Linfo IP’s willingness to file — even with a rapid exit — confirms the patent is being actively used for enforcement. The with-prejudice bar protects only Summer Moon; all other operators in the specialty coffee, quick-service, and food-franchise space remain potential targets.

What this case signals for food-tech and franchise IP enforcement
A pre-answer, with-prejudice exit in the Western District of Texas raises questions about patent viability and PAE enforcement strategy in the food-service sector.
With-prejudice dismissals before answer are a red flag for patent strength
When a plaintiff voluntarily dismisses with prejudice before the defendant has even answered, it typically signals either a settlement or a recognition that the patent position was unlikely to survive early scrutiny. IP teams facing similar assertion letters from Linfo IP should assess whether a firm but early response might accelerate resolution on favourable terms.
US9430131B1 remains live against other food and beverage operators
The with-prejudice bar applies only to Summer Moon Franchising LLC. Linfo IP retains the right to assert US9430131B1 against other defendants. Franchise operators, specialty coffee chains, and digital ordering platform providers in adjacent markets should monitor this patent and assess their exposure before receiving demand letters.
Linfo v Summer — key questions answered
The with-prejudice dismissal means Linfo IP, LLC permanently cannot assert US9430131B1 against Summer Moon Franchising LLC again. However, the bar is defendant-specific — Linfo IP retains the legal right to assert the same patent against other food-service or franchise operators. The dismissal was filed under Rule 41(a)(1)(A)(i) before Summer Moon answered, making it a unilateral plaintiff action requiring no court order.
The public record does not disclose the reason. A pre-answer, with-prejudice voluntary dismissal is consistent with either a confidential settlement (where the defendant may have paid or agreed to terms not reflected in public filings) or a plaintiff decision that the infringement theory was unlikely to survive early challenge. The mutual cost-bearing arrangement further suggests a negotiated exit rather than a unilateral concession.
US9430131B1 is a granted US utility patent held by Linfo IP, LLC, filed under application number US14/225422. It was asserted in the context of Summer Moon’s specialty coffee, tea, and baked goods business. Based on the litigation context, it is believed to cover digital interface, ordering, or information-management technology applicable to food-service retail operations. The precise claim scope requires review of the full patent specification and claims.
Federal Rule of Civil Procedure 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order by filing a notice of dismissal before the opposing party has served an answer or a motion for summary judgment. In this case, Summer Moon had not yet answered, so Linfo IP could dismiss unilaterally. The default under this rule is dismissal without prejudice, but Linfo IP expressly elected with prejudice, permanently surrendering its claims against this defendant.
The stipulated mutual cost-bearing clause — each party bears its own costs, expenses, and attorneys’ fees — contractually forecloses any subsequent motion for attorneys’ fees under 35 U.S.C. § 285 or other fee-shifting mechanisms between these parties. Summer Moon therefore cannot later seek exceptional-case fees from Linfo IP arising from this action. This arrangement is common in resolved PAE disputes where both sides prefer finality to continued litigation over fee entitlement.
