Vance v. Eco Fiber Inc.: Federal Circuit Appeal Voluntarily Dismissed
David Kevin Vance appealed to the U.S. Court of Appeals for the Federal Circuit against Eco Fiber Inc., asserting infringement of two patents covering insulated containers. The parties jointly agreed to dismiss the appeal under Fed. R. App. P. 42(b), with each side bearing its own costs, ending the proceeding after 245 days without a merits ruling.
Mutual dismissal ends Federal Circuit insulated container appeal
David Kevin Vance filed an infringement appeal at the U.S. Court of Appeals for the Federal Circuit on 8 August 2024, asserting two patents — utility patent US11772872B2 and design patent USD0964172S — against Eco Fiber Inc., targeting the company’s insulated container products. The case was docketed as Case No. 24-2180 and represented an appellate-level continuation of an underlying infringement action.
The appeal concluded on 10 April 2025 when the parties jointly agreed to dismiss the proceeding under Federal Rule of Appellate Procedure 42(b). The court ordered dismissal on consent, with each side bearing its own costs. Because the dismissal was mutual and cost-neutral, neither party secured a formal legal victory on the merits at the appellate level.
The 245-day duration suggests the parties may have reached a private resolution — whether a licensing arrangement, settlement, or commercial agreement — before the Federal Circuit issued any substantive ruling. The public record is silent on the specific terms that drove the agreement. The absence of a merits decision leaves the validity and enforceability of both patents formally untested at the appellate level, which may have implications for any future enforcement or challenge proceedings.

Voluntarily dismissed: what the Fed. R. App. P. 42(b) order means for both parties
Fed. R. App. P. 42(b) dismissal: no merits ruling
Federal Rule of Appellate Procedure 42(b) permits parties to jointly dismiss an appeal by stipulation. The court’s order reflects mutual consent rather than any judicial assessment of the underlying infringement claims. No appellate panel reviewed the patents’ validity, claim scope, or the alleged infringement — meaning the legal landscape for both patents remains formally unchanged at the appellate level.
Procedural dismissalWith or without prejudice? The public record is silent
The court’s order records a voluntary dismissal under Rule 42(b) but does not specify whether the dismissal was with or without prejudice. This distinction is commercially significant: a with-prejudice dismissal would bar Vance from re-filing the same appellate claims, while a without-prejudice dismissal could preserve that option. Practitioners should not assume either characterisation from the public docket alone.
Prejudice status unconfirmedVance retains patents but gains no appellate vindication
David Kevin Vance exits the Federal Circuit appeal without an infringement finding in his favour, but also without any adverse ruling on the validity or scope of US11772872B2 or USD0964172S. The patents remain enforceable on their face. Whether any private settlement or licensing deal was reached — which would represent a commercial win — cannot be confirmed from the public record.
No merits adjudicationEco Fiber escapes appellate ruling but faces residual risk
Eco Fiber Inc. avoids an adverse Federal Circuit ruling, and the cost-neutral order imposes no financial penalty. However, because neither patent was invalidated or found non-infringed at the appellate level, the underlying IP exposure is not formally extinguished. Eco Fiber’s insulated container products could potentially face renewed assertion if the dismissal was without prejudice and circumstances change.

Official order — verbatim text
The order’s language — ‘The parties having so agreed’ — confirms this was a fully consensual dismissal with no judicial input on the merits. The invocation of Fed. R. App. P. 42(b) is a purely procedural mechanism. Critically, the order is silent on prejudice, meaning practitioners cannot infer from the court’s text alone whether Vance could re-assert these claims in a future appellate proceeding. The cost-neutrality clause suggests neither party conceded a stronger position.
US11772872B2 & USD0964172S — insulated container utility and design patents
US11772872B2 is a utility patent protecting the functional aspects of insulated container technology, filed under application number US17/552408. USD0964172S is a design patent — filed as US35/511537 — protecting the ornamental appearance of an insulated container product. Together, they represent a dual-layer IP strategy covering both how the product works and how it looks, which is a common approach in the consumer goods and thermal packaging sector.
The strategic pairing of a utility and design patent over the same product category heightens the enforcement barrier for competitors: a challenger must design around both the functional claims of the utility patent and the ornamental scope of the design patent. For companies developing insulated containers, lunch boxes, coolers, or similar thermal packaging products, both patents warrant close monitoring. The absence of any appellate merits ruling means neither patent has been tested for validity or claim scope at the Federal Circuit level, preserving their full enforcement potential.
Should you run an FTO against US11772872B2 and USD0964172S?
Any company designing, manufacturing, or importing insulated containers — including coolers, thermal totes, food delivery packaging, or similar products — should assess freedom to operate against both US11772872B2 and USD0964172S. The utility patent’s functional claims and the design patent’s ornamental scope together create a broad enforcement perimeter. Because neither patent has been narrowed or invalidated by an appellate court, they carry maximum face value as of the date of this case’s dismissal.
PatSnap Eureka’s FTO Search Agent can map the independent and dependent claims of US11772872B2 against your product specifications and identify prior art that could inform a validity challenge to USD0964172S’s ornamental scope. Eureka’s portfolio monitoring tools also flag new continuations or related filings by the same inventor, helping your team stay ahead of evolving enforcement risk in the insulated container space.

What this case signals for the insulated container IP landscape
A consent dismissal at the Federal Circuit, cost-neutral and silent on merits, typically signals a private resolution — and unresolved patent risk.
Consent dismissals at the Federal Circuit often mask private deal terms
When both parties agree to dismiss a Federal Circuit appeal under Rule 42(b) with each side bearing its own costs, it frequently suggests a licensing agreement, settlement payment, or commercial arrangement was reached privately. IP teams monitoring competitors should treat such dismissals as potential signals of resolved — but undisclosed — licensing activity rather than clean victories for either side.
Both patents remain legally untested at the appellate level
Neither US11772872B2 nor USD0964172S received any appellate scrutiny of validity or claim scope. For competitors in the insulated container market, this means these patents carry no appellate narrowing or invalidation history, sustaining their full face value as enforcement tools. Any product team operating in this space should treat both patents as live enforcement risk.
VANCE v ECO — key questions answered
The Federal Circuit dismissed the appeal under Fed. R. App. P. 42(b) on consent of both parties, with each side bearing its own costs. No merits ruling was issued on the infringement claims or the validity of US11772872B2 or USD0964172S. The public record does not specify whether the dismissal was with or without prejudice.
Two patents were asserted: US11772872B2, a utility patent covering insulated container technology filed under application US17/552408, and USD0964172S, a design patent protecting the ornamental appearance of an insulated container filed under application US35/511537. Both remain formally unreviewed at the appellate level following the consent dismissal.
Neither party received a merits ruling. The appeal was dismissed by mutual agreement under Fed. R. App. P. 42(b). Eco Fiber avoided an adverse ruling, but neither patent was found invalid or non-infringed by the Federal Circuit. The outcome is best characterised as a procedural termination rather than a defendant victory.
Yes. The consent dismissal did not affect the enforceability of either patent. No validity challenge was adjudicated. Both patents retain their granted scope and remain potential enforcement tools in the insulated container market. Competitors should assess FTO risk accordingly.
Rule 42(b) of the Federal Rules of Appellate Procedure allows parties to dismiss an appeal by stipulation without requiring court approval on the merits. It is a purely procedural mechanism that ends the appellate proceeding without any judicial assessment of the underlying legal or factual issues. Such dismissals are often associated with private settlements or licensing resolutions reached between the parties.
