Evergreen Adhesives v. 3M Co.: Spray Adhesive Patent Suit Dismissed With Prejudice
Evergreen Adhesives, Inc. filed suit against 3M Co. and GTA-NHT, Inc. in the Massachusetts District Court alleging infringement of US7705056B1, a patent covering spray adhesive technology, across six of 3M’s commercial cylinder spray adhesive products. The parties jointly stipulated to dismiss the entire lawsuit with prejudice after 907 days, with each side bearing its own legal fees and costs.
Adhesive patent battle ends in mutual stipulated dismissal
Evergreen Adhesives, Inc. initiated this infringement action on 27 May 2022 in the U.S. District Court for the District of Massachusetts before Judge George A. O’Toole, Jr. The suit targeted 3M Co. and co-defendant GTA-NHT, Inc., asserting that six of 3M’s commercially marketed cylinder spray adhesive products — including the Foam Fast 74, General Purpose 60CA, Hi-Strength 94, HoldFast 70, and Hi-Strength 94 ET lines — infringed US7705056B1, a patent directed to spray adhesive formulations.
The case closed on 19 November 2024 when both parties filed a stipulation of dismissal with prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii). A dismissal with prejudice is a final adjudication on the merits as a matter of law, meaning Evergreen is permanently barred from reasserting the same infringement claims against 3M and GTA-NHT based on the same patent. Notably, the stipulation provides that each party bears its own attorneys’ fees and costs, suggesting a negotiated resolution with no monetary concession publicly recorded.
The 907-day duration — spanning pre-trial motions, discovery, and claim construction phases typical of a D. Mass. patent action — indicates the parties litigated substantively before reaching this resolution. The ‘each party bears its own fees’ structure, combined with the with-prejudice dismissal rather than a settlement with payment, is consistent with either a licensing agreement reached privately, a commercial arrangement outside the court record, or a strategic decision by Evergreen to withdraw following adverse litigation developments. The public record does not disclose the specific commercial terms, if any, that accompanied the dismissal.

Dismissed with prejudice: what the Rule 41 stipulation means for both parties
Rule 41(a)(1)(A)(ii) — stipulated dismissal, not a court judgment
Under FRCP 41(a)(1)(A)(ii), parties may jointly stipulate to dismiss an action without a court order once the defendant has answered or moved for summary judgment. A dismissal with prejudice operates as a final judgment on the merits. Critically, this mechanism is initiated by the parties themselves — the court need not issue a ruling — making it a favoured tool for litigation exits that may coincide with undisclosed private arrangements.
Stipulated — no merits ruling issuedEvergreen loses its right to re-litigate these infringement claims
A with-prejudice dismissal permanently extinguishes Evergreen’s ability to refile the same infringement claims against 3M and GTA-NHT under US7705056B1 for the accused products. Unless confidential terms accompany the stipulation — such as a licensing arrangement or cross-license — Evergreen receives no publicly recorded relief. The 907-day investment in litigation without a public damages award is notable and suggests either a private commercial resolution or a decision that continued litigation was no longer strategically warranted.
Claims barred — no public damages recorded3M secures permanent closure — accused products no longer at litigation risk
3M Co. and GTA-NHT, Inc. emerge from this dismissal without any public finding of infringement and with the lawsuit permanently closed. The accused product lines — including the Foam Fast 74, 60CA, HoldFast 70, and Hi-Strength 94 variants — face no further infringement exposure from Evergreen under US7705056B1 via this action. The ‘each party bears own costs’ provision means 3M avoids any fee-shifting, consistent with a negotiated exit rather than a clear litigation win.
No infringement finding — litigation closedSpray adhesive IP landscape: patent survives, future enforcement remains possible
US7705056B1 remains in force and is not invalidated by this dismissal. Evergreen retains the right to assert it against other parties in future actions. For competitors in the cylinder spray adhesive market beyond 3M and GTA-NHT, the patent continues to represent a potential enforcement risk. Companies formulating or commercialising contact spray adhesives — particularly in the construction, furniture, and industrial fabrication sectors — should consider evaluating their product designs against the claims of US7705056B1.

Official order — verbatim text
The stipulation invokes Rule 41(a)(1)(A)(ii), requiring agreement from all parties who have appeared — indicating 3M and GTA-NHT both consented to the terms. The ‘with prejudice’ designation is the operative legal consequence: it forecloses any future action by Evergreen on the same claims, functioning as a res judicata bar. The ‘each party bears its own fees and costs’ clause, absent any fee-shifting motion or exceptional-case finding under 35 U.S.C. § 285, is characteristic of negotiated exits rather than unilateral capitulation.
US7705056B1 — Cylinder Spray Adhesive Formulation Technology
US7705056B1 (application number US10/979575) is a granted U.S. patent held by Evergreen Adhesives, Inc. covering formulations and compositions used in cylinder spray adhesive products — the type deployed widely across construction, furniture manufacturing, foam bonding, and industrial lamination. The patent’s claims are directed to the adhesive chemistry and formulation architecture that enables pressurised spray delivery from cylinder format, a dominant commercial packaging standard for industrial contact adhesives.
The breadth of accused products — spanning 3M’s Foam Fast 74, General Purpose 60CA, Hi-Strength 94 (multiple variants), HoldFast 70, and Hi-Strength 94 ET — suggests Evergreen’s claims map broadly across a range of contact adhesive chemistries within 3M’s commercial portfolio. For competitors in the industrial adhesive sector, this patent represents meaningful enforcement risk: 3M’s cylinder spray adhesive line is among the most widely distributed in North America, and a patent covering formulation fundamentals could affect any comparable product. US7705056B1 was not invalidated in this proceeding and remains a live enforcement asset.
Should your adhesive product be cleared against US7705056B1?
Any company developing, manufacturing, or distributing cylinder spray adhesive products — particularly contact adhesives in pressurised or aerosol cylinder format — should treat US7705056B1 as a live FTO concern. The patent survived a 907-day infringement action against the world’s largest diversified adhesive manufacturer. Its claims are sufficiently broad to have implicated six distinct 3M product lines across multiple adhesive strength categories. R&D teams reformulating legacy products or launching new spray adhesive lines face non-trivial clearance exposure.

What this case signals for the industrial adhesives IP landscape
A 907-day patent dispute over spray adhesive technology ending in a fee-neutral, with-prejudice dismissal carries specific signals for enforcement strategy and FTO planning.
With-prejudice exits after prolonged litigation often signal private terms
When litigation runs nearly 2.5 years and closes with a mutual stipulation bearing its own costs and no public damages, the pattern is consistent with an undisclosed commercial resolution — licensing, cross-license, or market arrangement. IP teams monitoring competitors should not read ‘dismissed with prejudice’ as a clean defendant win in all cases.
US7705056B1 remains live — adhesive formulators face ongoing enforcement risk
The patent-in-suit was not invalidated, disclaimed, or transferred in the public record. Any company developing or selling cylinder spray adhesive products commercially — particularly those competing with 3M’s Foam Fast, HoldFast, or Hi-Strength product lines — should run a formal FTO assessment against the claims of US7705056B1 before scaling commercialisation.
Evergreen v 3M — key questions answered
In Case No. 1:22-cv-10821, the parties filed a stipulated dismissal with prejudice under FRCP 41(a)(1)(A)(ii) on 19 November 2024. A dismissal with prejudice operates as a final adjudication on the merits, permanently barring Evergreen Adhesives from re-filing the same infringement claims against 3M and GTA-NHT under US7705056B1 for the accused products.
Evergreen Adhesives accused six 3M cylinder spray adhesive products: 3M Foam Fast 74, General Purpose 60CA, Hi-Strength Post Forming 94 CA (Clear or Red), HiStrength Postforming 94 CA (Red, Fragrance-Free), HoldFast 70 (Clear), and Hi-Strength 94 ET Spray Adhesive. These span multiple adhesive strength and application categories within 3M’s commercial portfolio.
No. The public record shows no invalidity finding or inter partes review outcome that would extinguish US7705056B1. The case was dismissed by mutual stipulation without any merits ruling. The patent remains in force and represents a live enforcement asset that third-party adhesive manufacturers should evaluate in their FTO processes.
The public record does not specify GTA-NHT, Inc.’s precise commercial role. However, naming both 3M Co. and GTA-NHT, Inc. as co-defendants is consistent with a strategy of pursuing entities across the manufacturing or distribution chain — a common approach in patent enforcement intended to maximise litigation pressure on multiple links in the product supply and sales network.
The ‘each party bears its own fees and costs’ provision in the Rule 41 stipulation means neither side sought or obtained fee-shifting under 35 U.S.C. § 285 (exceptional case) or other cost-shifting mechanisms. This neutral cost allocation is typical of negotiated exits and suggests both parties reached a mutually acceptable resolution rather than one party capitulating entirely, though the specific commercial terms, if any, are not part of the public record.
