Eco Fiber Inc. v. Vance & Yukon Packaging: Cold-Chain Patent Settled With Prejudice
Eco Fiber Inc. filed a patent infringement suit in the Western District of North Carolina against David Kevin Vance and Yukon Packaging, LLC over a 3-piece cold-chain packaging product. After securing a preliminary injunction and $10,000 bond within six weeks of filing, the parties reached a settlement and jointly dismissed the action with prejudice after 358 days.
Cold-Chain Packaging Dispute Ends in Settlement After Injunction Win
Eco Fiber Inc. filed its complaint on May 9, 2024 in the Western District of North Carolina, asserting infringement of US11772872B2 and USD0964172S against David Kevin Vance and Yukon Packaging, LLC in connection with a 3-piece cold-chain product. Within 24 hours, Eco Fiber moved for a preliminary injunction. Following a June 18 hearing, the court granted the injunction on June 21, 2024 and required Eco Fiber to post a $10,000 cash bond — a notable early win for the plaintiff.
Defendant Vance filed a Notice of Interlocutory Appeal to the Federal Circuit on July 1, 2024, seeking to challenge the preliminary injunction order. That appellate proceeding was ultimately dismissed on April 10, 2025 by agreement of the parties. The following day, the parties jointly moved to dissolve the injunction, release the bond, and dismiss the entire action with prejudice under Fed. R. Civ. P. 41(a)(1)(A)(ii). The court granted the motion on May 2, 2025, returning the bond to Eco Fiber and permanently dissolving the injunction.
The 358-day resolution, while not unusually swift, is notable for its trajectory: an early injunction grant, an interlocutory appeal to the Federal Circuit, and then a comprehensive settlement that closed both proceedings simultaneously. The decision to settle with prejudice — rather than without — suggests the parties reached a durable resolution, potentially including a licensing or non-compete arrangement, though the financial terms remain confidential and are not reflected in the public record.
Filing to Dismissed with Prejudice in 358 days
358 days — faster than the median W.D.N.C. patent case, resolved pre-trial via settlement
Dismissed with prejudice: what the settlement means for both parties
Rule 41 stipulated dismissal with prejudice — claims permanently closed
The dismissal was effectuated under Fed. R. Civ. P. 41(a)(1)(A)(ii), which permits dismissal without a court order when all appearing parties sign a stipulation. A dismissal with prejudice operates as a final adjudication on the merits — Eco Fiber cannot re-file these same patent infringement claims against these defendants. The court simultaneously dissolved the preliminary injunction and directed return of the $10,000 bond to Eco Fiber.
Rule 41(a)(1)(A)(ii) stipulationEco Fiber recovers bond and exits with leverage intact
Eco Fiber secured a preliminary injunction within six weeks of filing — a significant early-stage win that likely shaped settlement leverage. The bond is returned, costs are not awarded against it, and the dismissal with prejudice reflects a negotiated resolution rather than a concession. The confidential settlement terms may include licensing rights, design restrictions, or a covenant not to sue, though none of this is confirmed in the public record.
Bond returned; settled from position of strengthInjunction dissolved but dismissal with prejudice limits future exposure
Vance and Yukon Packaging faced an active preliminary injunction for approximately ten months and pursued an interlocutory appeal to the Federal Circuit — a costly and time-consuming strategy that was ultimately abandoned by agreement. The injunction is now dissolved, but the with-prejudice dismissal means defendants also cannot re-litigate the underlying dispute. Each side bearing its own costs suggests neither party claimed a clear-cut win at the settlement table.
Injunction dissolved; Federal Circuit appeal droppedCold-chain packaging IP signals active enforcement posture
Eco Fiber’s willingness to seek — and obtain — a preliminary injunction within weeks of filing signals an aggressive enforcement strategy for its cold-chain packaging IP. Competitors and packaging converters working with 3-piece cold-chain designs should treat US11772872B2 and USD0964172S as actively enforced assets. The interlocutory Federal Circuit involvement, even in a case that settled, adds litigation cost pressure that may deter future infringers from contesting similar claims.

Official order — verbatim text
The court’s order reflects a fully consensual resolution: all parties signed both the joint motion and its supporting memorandum, satisfying the Rule 41(a)(1)(A)(ii) stipulation requirement without judicial merits adjudication. The dismissal with prejudice — expressly confirmed in the order — permanently extinguishes Eco Fiber’s ability to re-assert these claims against these defendants. The simultaneous dissolution of the injunction and return of the $10,000 bond closes the procedural loop cleanly, leaving no lingering equitable obligations on either side.
US11772872B2 & USD0964172S — 3-Piece Cold-Chain Packaging Technology
US11772872B2 covers a 3-piece cold-chain product — a packaging system designed to maintain temperature-controlled integrity during shipping and distribution. Cold-chain packaging patents typically protect structural innovations in insulation configuration, assembly mechanics, and thermal performance. USD0964172S is a design patent protecting the ornamental appearance of the same product, providing a separate, visually distinct IP layer. Together, these two patents create overlapping protection across both functional and aesthetic dimensions of the product.
Eco Fiber’s decision to assert both a utility and a design patent over the same cold-chain product reflects a sophisticated IP stacking strategy common among packaging innovators seeking to maximise enforcement leverage. For competitors in temperature-controlled logistics, food shipping, and pharmaceutical cold-chain packaging, these patents represent a meaningful exclusionary zone. Any company developing or sourcing a 3-piece insulated cold-chain packaging solution should conduct clearance analysis against both assets before commercialisation.
Should you run an FTO against US11772872B2 and USD0964172S?
Any manufacturer, converter, or distributor working with 3-piece cold-chain packaging formats should treat these patents as active risk assets. Eco Fiber has demonstrated a willingness to seek immediate preliminary injunctive relief — a court-granted injunction arrived within 43 days of filing. Product teams launching insulated shipping solutions, particularly multi-component cold-chain designs, face meaningful infringement exposure if their designs are not cleared against both the utility and design patent claims.

Portfolio viewWhat this case signals for the cold-chain packaging IP landscape
An early injunction, a Federal Circuit detour, and a with-prejudice settlement — this case has strategic lessons beyond its outcome.
Preliminary injunctions in packaging cases can force early settlement
Eco Fiber obtained a preliminary injunction just 43 days after filing. In product-based patent disputes, injunctive relief at this stage dramatically alters settlement leverage. Companies in cold-chain and insulated packaging should evaluate their design freedom before product launch — not after receiving a cease-and-desist.
With-prejudice dismissals signal durable deals — not plaintiff retreats
A Rule 41 dismissal with prejudice is a mutual, permanent closure. When a plaintiff who has already won an injunction agrees to this outcome, it typically suggests the commercial objectives were met through confidential settlement terms — such as licensing or product design changes — rather than litigation failure.
Design patents and utility patents: why dual assertion strengthens leverage
Eco Fiber asserted both a utility patent (US11772872B2) and a design patent (USD0964172S) over the same product. This dual-assertion strategy creates overlapping enforcement vectors — functional and ornamental — making design-arounds significantly harder and increasing the cost of defence for the accused infringer.
Interlocutory Federal Circuit appeals: a costly gamble on injunction orders
Vance’s interlocutory appeal to the Federal Circuit added a parallel proceeding that had to be dismissed separately as part of the settlement. This tactic raises total litigation costs substantially and rarely succeeds in reversing preliminary injunctions. Patent defendants should weigh the cost-benefit of this strategy against early licensing discussions.
Eco v David — key questions answered
Eco Fiber filed a patent infringement suit in May 2024 in the Western District of North Carolina over a 3-piece cold-chain product, asserting US11772872B2 and USD0964172S. The court granted a preliminary injunction in June 2024. After Vance filed an interlocutory appeal to the Federal Circuit, the parties settled and jointly dismissed the case with prejudice on May 2, 2025.
A dismissal with prejudice is a final, permanent termination of the lawsuit. Eco Fiber cannot re-file these same patent infringement claims against Vance or Yukon Packaging in the future. It typically reflects a negotiated settlement in which the plaintiff’s commercial objectives were addressed through confidential terms, rather than a concession of invalidity or non-infringement.
Eco Fiber asserted two patents: US11772872B2, a utility patent covering a 3-piece cold-chain packaging product, and USD0964172S, a design patent protecting the ornamental appearance of the same product. The dual assertion strategy provided overlapping functional and aesthetic IP protection over the accused cold-chain packaging.
Defendant David Kevin Vance filed a Notice of Interlocutory Appeal to the U.S. Court of Appeals for the Federal Circuit on July 1, 2024, challenging the district court’s preliminary injunction order. The Federal Circuit has exclusive jurisdiction over patent appeals. The appeal was ultimately dismissed on April 10, 2025 by agreement of the parties as part of the broader settlement.
The court required Eco Fiber to post a $10,000 cash bond as a condition of the preliminary injunction under Fed. R. Civ. P. 65(c). As part of the joint settlement motion, the parties agreed to release the bond back to Eco Fiber. The court’s May 2, 2025 order directed the Clerk of Court to remit those security payments to the plaintiff.
