Tikiz Franchising v. Kona Ice: Federal Circuit Appeal Voluntarily Dismissed
Tikiz Franchising, LLC appealed an infringement action against shaved-ice rival Kona Ice, Inc. over US9751447B2 — a patent covering a liquid toppings dispensing system used on mobile food vehicles. The parties agreed to dismiss the appeal after just 116 days, with each side bearing its own costs.
A competitor IP dispute resolved before Federal Circuit merits review
Tikiz Franchising, LLC — a mobile shaved-ice franchise operator and holder of US9751447B2 — brought an infringement action against Kona Ice, Inc., a rival mobile frozen-treat franchisor. The patent at issue, US9751447B2, claims a liquid toppings dispensing system, the kind of self-serve flavoring mechanism that distinguishes both companies’ customer experience. The appeal, docketed as Case No. 25-1279, was filed with the Court of Appeals for the Federal Circuit on 12 December 2024.
The proceeding ended on 7 April 2025 when the parties jointly agreed to dismiss under Federal Rule of Appellate Procedure 42(b). The court ordered the dismissal and specified that each side would bear its own costs. Because the dismissal was voluntary and the basis of termination does not specify whether it was with or without prejudice, the public record is silent on that distinction — leaving the door open to future proceedings in theory, though the agreed cost allocation suggests a negotiated resolution.
The 116-day lifespan is notably short for a Federal Circuit appeal, suggesting the parties reached an accommodation quickly — possibly a licensing arrangement, covenant not to sue, or commercial settlement — rather than litigating to judgment. What drove that accommodation, and whether any financial terms were exchanged, is not apparent from the public docket. The absence of a merits ruling means the validity and scope of US9751447B2 remain untested at the appellate level.

Voluntarily dismissed: what the agreed exit means for both parties
Fed. R. App. P. 42(b): agreed voluntary dismissal at the appellate level
Rule 42(b) allows parties to dismiss an appeal by filing a signed agreement. Critically, no merits ruling is issued — the Federal Circuit makes no finding on patent validity, claim scope, or infringement. The dismissal is procedural only. Because the record does not specify with or without prejudice, the precise preclusive effect on future litigation is unclear from public filings alone.
No merits adjudicationThe public record is silent on prejudice — what that means
A dismissal ‘with prejudice’ bars refiling the same claim; ‘without prejudice’ preserves that right. Under Rule 42(b), the parties may specify either, but here the court order simply states ‘DISMISSED’ without qualification. The public docket does not resolve this ambiguity. Practitioners should treat the enforceability of US9751447B2 as an open question until further proceedings or disclosures clarify the terms of any underlying agreement.
Prejudice terms undisclosedKona Ice exits without an adverse ruling — but patent risk persists
Kona Ice avoids an appellate finding of infringement and pays no court-ordered costs. However, the voluntary nature of the dismissal — rather than a win on the merits — means US9751447B2 has not been invalidated or held non-infringed. Kona Ice’s freedom to operate with its liquid toppings dispensing system is not formally confirmed by this outcome, and future assertion of the patent remains possible depending on the undisclosed terms.
No invalidity findingMobile food franchise IP: a live competitive battleground
The rapid settlement of this appeal — before any substantive Federal Circuit briefing — suggests both franchisors placed commercial value on resolving the dispute privately. For other operators in the mobile food and frozen-treat sector, US9751447B2 remains a live, unchallenged patent. Competitors using self-serve liquid toppings dispensing technology on mobile vehicles should treat this outcome as a signal to conduct FTO analysis rather than rely on this dismissal as clearance.

Official order — verbatim text
The court’s order tracks the precise language of Fed. R. App. P. 42(b), confirming this was a consent dismissal rather than a unilateral withdrawal. Two elements are notable: the dismissal is not qualified as ‘with’ or ‘without’ prejudice in the order itself, and the symmetric cost allocation — ‘each side shall bear their own costs’ — diverges from outcomes where one party’s stronger position results in cost-shifting. No appellate standard of review was applied; no panel assessed the district court record for reversible error. The patent’s validity and the infringement allegations therefore remain unresolved on the public record.
US9751447B2 — Liquid Toppings Dispensing System for Mobile Food Vehicles
US9751447B2, filed under application number US14/870439, protects a liquid toppings dispensing system — the mechanism by which customers apply flavored syrups or liquid toppings to shaved ice or frozen treats on mobile food vehicles. This type of self-serve dispensing apparatus is central to the differentiated customer experience offered by both Tikiz Franchising and Kona Ice. The patent places Tikiz in a potentially dominant enforcement position over any competitor using materially similar dispensing architecture in a mobile food context.
From a competitive intelligence standpoint, US9751447B2 represents a functional patent in a high-growth mobile food franchise sector. Kona Ice — with a large national franchise footprint — is precisely the kind of competitor that makes this patent commercially significant. The fact that this dispute reached the Federal Circuit before resolving privately suggests both parties assigned material value to the patent’s scope. For R&D teams designing dispensing systems for food trucks, carts, or mobile franchise units, this patent warrants close analysis before product architecture is finalised.
Should you run an FTO against US9751447B2?
Any company developing or deploying a liquid toppings or flavored syrup dispensing mechanism on a mobile food vehicle — whether as a franchisor, OEM equipment supplier, or independent operator — should conduct a freedom-to-operate analysis against US9751447B2. The voluntary dismissal of this appeal does not constitute judicial clearance and creates no estoppel. The patent remains granted, enforceable, and its claim scope has not been construed by any appellate court.

Cases involving infringement appeals at the Federal Circuit in food service dispensing system technology, particularly mobile and franchise contexts, resolved by voluntary dismissal.
What this case signals for the mobile food franchise IP landscape
A fast voluntary dismissal at the Federal Circuit rarely ends the story — it typically reflects a negotiated commercial outcome.
Speed of dismissal suggests a deal, not capitulation
At 116 days, this appeal closed before full appellate briefing would typically be complete. That pace is consistent with a licensing deal, covenant not to sue, or broader commercial settlement reached after the appeal was docketed. IP teams monitoring the mobile food vehicle sector should watch for any subsequent licensing disclosures or cross-use of the dispensing technology.
US9751447B2 survives unchallenged — FTO exposure remains real
Because no merits ruling was issued, US9751447B2 has not been invalidated or construed by the Federal Circuit. Any competitor deploying a liquid toppings dispensing system on mobile food vehicles — whether in franchising or direct retail — faces unresolved infringement risk under this patent. Relying on this dismissal as implicit clearance would be analytically unsound.
Tikiz v Kona — key questions answered
The voluntary dismissal under Fed. R. App. P. 42(b) means no merits ruling was issued by the Federal Circuit. US9751447B2 remains a valid, granted patent. Its claim scope and enforceability were not adjudicated, and the dismissal creates no estoppel or invalidity finding that competitors could rely upon.
The court order does not specify with or without prejudice. The public docket is silent on this point. Under Rule 42(b), parties may agree either way, but the order here simply states ‘DISMISSED.’ The precise preclusive effect on future litigation between these parties is therefore unclear from publicly available records alone.
The patent asserted was US9751447B2, filed under application number US14/870439. It covers a liquid toppings dispensing system, specifically the self-serve flavoring mechanism used on mobile food vehicles — a core feature of both the Tikiz and Kona Ice franchise models.
At 116 days, the appeal closed well before full appellate briefing would typically conclude at the Federal Circuit. This pace is consistent with the parties reaching a negotiated resolution — potentially a license, covenant not to sue, or commercial settlement — shortly after the appeal was docketed. No public disclosure of the underlying terms has been identified.
No. The dismissal is procedural and does not constitute a judicial finding of non-infringement or invalidity. US9751447B2 remains enforceable. Competitors using liquid toppings dispensing systems on mobile food vehicles should conduct independent FTO analysis and should not treat this dismissal as implicit clearance to operate freely under the patent.
