Eco Fiber Inc. v. Yukon Packaging: Industrial Fiber Insulation Patent Case Remanded in 32 Days
Eco Fiber Inc. filed a patent infringement action against Yukon Packaging, LLC and four co-defendants in the North Carolina Western District Court, asserting US11772872B2 covering insulating pads made from industrial waste fibers. The case was remanded just 32 days after filing, with the court denying both the motion to remand and the motion for preliminary injunction as moot.
Industrial Fiber Insulation IP Dispute Ends in Procedural Remand
On May 17, 2024, Eco Fiber Inc. filed a patent infringement action in the North Carolina Western District Court against Yukon Packaging, LLC, David Kevin Vance, Christopher James Poore, Rabindranauth Heeralall, and Zone 1 Consulting, LLC. The asserted patent, US11772872B2, covers EFI products comprising three separate insulating pads manufactured from industrial waste fibers — a sustainable packaging technology with applications in temperature-sensitive logistics and insulated shipping materials.
The case closed on June 18, 2024 — just 32 days after filing — when the court issued an order remanding the matter. The court simultaneously denied Eco Fiber’s Motion to Remand (Doc. No. 40) and Motion for Preliminary Injunction (Doc. No. 11) as moot. A remand at this stage typically signals that the court determined it lacked proper jurisdiction, most likely because the case was originally a state court matter that defendants removed to federal court and the removal was found procedurally defective — though the precise grounds are not fully specified in the public record.
The 32-day resolution timeline is unusually swift and consistent with a purely procedural disposition rather than any merits adjudication. The denial of the preliminary injunction as moot — rather than on substantive grounds — means there is no public record of the court’s assessment of Eco Fiber’s likelihood of success or the strength of US11772872B2. The underlying infringement claims remain unresolved, and Eco Fiber may pursue the action in the appropriate forum. What drove the jurisdictional outcome and whether the parties subsequently settled or re-filed remains unknown from publicly available records.

32 days — resolved before first substantive merits hearing, well below district court average
Case remanded: what the court’s order means for both parties
Remand returns the case to its originating court
A remand order means the federal district court determined it should not retain jurisdiction over the matter — most commonly because the case originated in state court and was removed to federal court, but the removal was found defective or jurisdictional prerequisites were unmet. The federal court did not rule on the merits of the infringement claims. Both the preliminary injunction and the motion to remand were denied as moot, meaning neither received substantive adjudication.
Procedural — no merits rulingEco Fiber’s infringement claims remain live but unresolved
For Eco Fiber Inc., the remand is neither a win nor a loss on the merits. The patent — US11772872B2 — has not been challenged, invalidated, or found infringed at this stage. However, the denial of the preliminary injunction as moot means Eco Fiber did not obtain immediate injunctive relief against Yukon Packaging. The company retains the right to pursue its claims in the appropriate court, and the patent’s enforceability is unaffected by this procedural outcome.
Claims alive — no injunction grantedYukon Packaging avoids federal forum — for now
The remand effectively removes Yukon Packaging and co-defendants from federal district court proceedings, at least under this filing. No infringement finding was made, and the defendants face no damages or injunction from this action. However, if Eco Fiber re-files in the appropriate forum — whether state court or a different federal venue — the substantive infringement dispute over the industrial waste fiber insulating pad technology will need to be addressed on the merits.
No liability — forum shiftedSustainable packaging IP enforcement remains unsettled
The remand leaves the IP landscape around industrial waste fiber insulating pads unresolved. Competitors and supply chain participants in sustainable packaging cannot draw conclusions about the scope or enforceability of US11772872B2 from this outcome. Companies developing or sourcing EFI-type insulating solutions should monitor whether Eco Fiber pursues re-filing, as a merits adjudication — including any claim construction ruling — could have significant implications for the sector.

Official order — verbatim text
The court’s order is purely procedural: the remand terminates federal jurisdiction without any assessment of patent validity, infringement, or claim scope. Denying both pending motions as moot confirms that no substantive legal standards — including the four-factor preliminary injunction test — were applied. For practitioners, the order leaves every merits question open. The public record does not specify the precise jurisdictional defect that prompted remand, which limits analysis of whether re-filing in federal court remains viable for Eco Fiber.
US11772872B2 — Industrial Waste Fiber Insulating Pad Technology
US11772872B2, filed under application number US17/552408, protects EFI products comprising three distinct insulating pads manufactured from industrial waste fibers. The patent sits at the intersection of sustainable materials engineering and protective packaging — covering a construction method that repurposes industrial fiber byproducts into high-performance thermal insulation layers. The three-pad architecture suggests a layered barrier system designed to meet temperature-control requirements for cold-chain or perishable goods shipping applications.
The patent’s commercial relevance is amplified by the growing regulatory and consumer pressure on single-use plastic packaging. Industrial waste fiber insulation represents a credible, scalable alternative — making US11772872B2 a strategically valuable asset in a sector where sustainable packaging IP is still relatively sparse. Any company developing fiber-based insulated mailers, shipping liners, or cold-chain packaging solutions that incorporate multi-layer waste fiber constructions should assess whether their product falls within the claim scope of this patent, particularly given Eco Fiber’s demonstrated willingness to litigate.
Should your team run an FTO against US11772872B2?
If your organisation designs, sources, or manufactures insulating packaging products that incorporate industrial or recycled fiber materials — especially multi-layer or multi-pad configurations — US11772872B2 warrants direct FTO scrutiny. Eco Fiber’s decision to pursue litigation against a packaging company and a consulting firm signals active enforcement intent. The unresolved nature of the underlying claims means the patent remains a live infringement risk for the sustainable packaging supply chain.

What this case signals for the sustainable packaging IP landscape
A 32-day procedural exit leaves the patent uncontested and enforcement risk unresolved for the industrial fiber insulation sector.
US11772872B2 remains fully enforceable after remand
The remand produced no validity ruling, no claim construction, and no infringement finding. Eco Fiber’s patent on industrial waste fiber insulating pads is intact and available for future enforcement. Competitors in sustainable packaging should not treat this outcome as a clearance signal.
Preliminary injunction risk not yet assessed by any court
Because the court denied the preliminary injunction motion as moot rather than on its merits, there is no judicial record on Eco Fiber’s likelihood of success, irreparable harm, or balance of equities. Any re-filed action could bring a new injunction motion with full merits review — a material risk for Yukon Packaging and similarly positioned defendants.
Eco v Yukon — key questions answered
The remand means the North Carolina Western District Court returned the case to its originating court without ruling on the merits of the patent infringement claims. US11772872B2 was not found valid or invalid, and no infringement determination was made. Eco Fiber retains the right to pursue its claims in the appropriate forum.
The preliminary injunction motion was denied as moot because the court remanded the entire case before it could conduct a substantive hearing. Once jurisdiction was terminated, all pending motions — including the injunction request — became procedurally moot. This means no court has yet assessed the four-factor injunction test on the merits of this dispute.
US11772872B2 covers EFI products comprising three separate insulating pads made from industrial waste fibers. The patent relates to sustainable packaging insulation, likely targeting cold-chain or temperature-sensitive shipping applications where recycled fiber materials replace conventional foam or plastic insulation.
The defendants are Yukon Packaging, LLC (primary defendant), David Kevin Vance, Christopher James Poore, Rabindranauth Heeralall, and Zone 1 Consulting, LLC. The inclusion of individual defendants and a consulting firm alongside the packaging company suggests Eco Fiber targeted the broader commercial network allegedly involved in infringing activity.
A remand is a procedural disposition, not a merits ruling, so it does not bar Eco Fiber from re-filing. The company may pursue its infringement claims under US11772872B2 in the court to which the case was remanded, or potentially in another appropriate forum. The patent’s validity and enforceability are unaffected by the remand order.
