Valmont Industries v. Better Metal: Tower Attachment Patent Dispute Dismissed With Prejudice
Valmont Industries, a major infrastructure manufacturer, sued Better Metal, LLC in the Middle District of Tennessee asserting four patents covering tower leg attachment and V-Mount lattice tower systems. The case ended in a stipulated dismissal with prejudice after 533 days — a resolution consistent with an out-of-court settlement between the parties.
Four-Patent Tower Attachment Dispute Ends in Stipulated Final Exit
Valmont Industries, Inc. — a global leader in infrastructure products including utility poles and communication towers — filed this infringement action against Better Metal, LLC on November 16, 2023, in the U.S. District Court for the Middle District of Tennessee. The complaint asserted four patents: US11274435B2, US10316511B1, US10590641B2, and US10968623B2, all directed at structural tower attachment technologies including the Tower Leg Attachment and V-Mount for Lattice Tower Attachment product lines.
The action terminated on May 2, 2025, via a Stipulation of Dismissal with Prejudice filed by both parties under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The court entered the dismissal accordingly and closed the file. A dismissal with prejudice bars Valmont from re-asserting these specific claims against Better Metal on the same patents, suggesting the parties reached a definitive resolution — most likely a private licensing agreement or settlement — rather than a default or contested judgment.
At 533 days, the case ran longer than many single-patent disputes, which may reflect the complexity of litigating four patents across related but distinct product configurations. The stipulated nature of the dismissal — filed jointly — is consistent with a negotiated exit rather than capitulation by either side. The financial terms, licensing scope, and any product design changes by Better Metal remain confidential and cannot be determined from the public docket.

Dismissed with prejudice: what the stipulated exit means for both parties
Rule 41(a)(1)(A)(ii) Stipulated Dismissal With Prejudice
Under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), both parties signed a stipulation to dismiss the action with prejudice. The court had no discretion to refuse — it entered the order ministerially. ‘With prejudice’ means Valmont cannot re-file these same claims against Better Metal on the asserted patents. This mechanism is the standard vehicle for implementing a privately negotiated settlement.
Voluntary, bilateral, finalValmont Secures a Final Exit — Likely on Negotiated Terms
Valmont agreed to dismiss with prejudice, forfeiting any right to re-litigate these claims. This suggests it received sufficient consideration — likely a licensing payment, royalty arrangement, or confirmed design-around — to justify closing the case permanently. The four-patent assertion gave Valmont significant leverage during negotiation, as Better Metal faced exposure across multiple patent claims covering related attachment configurations.
Settled — terms privateBetter Metal Avoids Judgment — but Faces Future Enforcement Risk
Better Metal escaped a court-imposed finding of infringement and any public damages award. However, the dismissal with prejudice protects it only from re-litigation of the specific claims in this action. Valmont’s four patents remain in force, and Better Metal’s future products could still face assertion if not covered by any license negotiated here. The scope of any immunity depends entirely on the private settlement agreement.
No judgment; patents remain activeTower Attachment IP Remains a Live Enforcement Risk for the Sector
Valmont’s willingness to pursue four patents across 533 days signals active enforcement of its tower attachment portfolio. Competitors and component manufacturers operating in the lattice tower and utility pole attachment market should treat US11274435B2, US10316511B1, US10590641B2, and US10968623B2 as live enforcement risks. The undisclosed settlement terms do nothing to limit Valmont’s ability to assert the same patents against other parties.

Official order — verbatim text
The dismissal order tracks the exact language of the parties’ joint stipulation, with the court acting in a ministerial capacity under Rule 41(a)(1)(A)(ii). The ‘with prejudice’ designation is legally significant: it operates as a final adjudication on the merits for res judicata purposes, permanently extinguishing Valmont’s right to re-assert these specific claims against Better Metal. The absence of any fee award or cost allocation in the public record suggests the parties addressed those matters — if at all — within the private settlement agreement.
US11274435B2 — Tower leg and lattice tower structural attachment systems
The four asserted patents — US11274435B2, US10316511B1, US10590641B2, and US10968623B2 — cover structural attachment systems used to mount equipment and components to utility and communication tower frameworks. The patents span Tower Leg Attachment and V-Mount for Lattice Tower Attachment configurations, reflecting an incremental innovation strategy where Valmont has built layered claim coverage across related attachment geometries and mounting methods filed between 2018 and 2020.
For the infrastructure and telecommunications tower hardware sector, these patents represent meaningful exclusionary coverage over how third-party equipment is secured to lattice and monopole tower structures — a critical interface in the deployment of 5G antennas, utility grid equipment, and communication hardware. Valmont’s willingness to assert all four patents simultaneously signals that it treats this portfolio as a commercially strategic asset, not merely a defensive filing, creating real clearance risk for competing hardware manufacturers.
Should your team run an FTO against Valmont’s tower attachment patents?
Any company manufacturing, importing, or selling tower leg attachment hardware, V-Mount systems, or functionally similar lattice tower mounting products should treat Valmont’s four-patent portfolio as an active clearance requirement. The fact that Valmont pursued litigation for 533 days — and extracted a with-prejudice dismissal — confirms this is an enforced portfolio. Product teams developing new attachment configurations should engage FTO analysis before commercial launch, not after receiving a demand letter.

What this case signals for the tower infrastructure IP landscape
Valmont’s four-patent assertion and multi-year pursuit suggest a structured enforcement strategy, not a one-off dispute.
Multi-patent stacking amplifies settlement leverage in structural IP disputes
Valmont asserted four overlapping patents covering closely related tower attachment configurations. This stacking strategy forces defendants to challenge validity and non-infringement across multiple claims simultaneously — substantially increasing litigation cost and risk. Companies in the structural hardware space should map their products against entire patent families, not individual claims.
Dismissal with prejudice after 533 days typically signals a paid-up resolution
Cases that run beyond one year before a stipulated dismissal with prejudice are rarely abandoned for no consideration. The timeline here — through discovery and pre-trial phases — suggests the parties had sufficient information to value the dispute and negotiate terms. This pattern is commonly seen in licensing-driven settlements where the patent holder extracts royalties or a lump-sum payment.
Valmont v Better — key questions answered
Valmont asserted four patents: US11274435B2, US10316511B1, US10590641B2, and US10968623B2. All four cover structural tower attachment technologies, specifically Tower Leg Attachment and V-Mount for Lattice Tower Attachment systems, as identified in the case filing in the Middle District of Tennessee.
The case was dismissed with prejudice pursuant to a joint Stipulation of Dismissal filed by both parties under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). This mechanism typically reflects a privately negotiated settlement. The with-prejudice designation permanently bars Valmont from re-asserting the same claims against Better Metal in a future action.
Not necessarily. A stipulated dismissal with prejudice under Rule 41(a)(1)(A)(ii) is not a merits judgment in favor of either party. It reflects a mutual agreement to end the litigation — most commonly following a settlement. Better Metal avoided a public infringement finding, but the underlying patents remain valid and enforceable against other parties.
Yes. The dismissal with prejudice only forecloses Valmont’s claims against Better Metal specifically. Patents US11274435B2, US10316511B1, US10590641B2, and US10968623B2 remain in force and can be asserted against any other party whose products fall within the claim scope. Competitors should not treat this settlement as reducing Valmont’s enforcement posture.
The V-Mount for Lattice Tower Attachment is a structural hardware product designed to secure equipment — such as antennas or utility components — to lattice tower frameworks using a V-shaped mounting bracket. Valmont holds patents covering specific configurations and methods for such attachments. Competing products using similar geometries or fastening approaches risk infringing one or more of Valmont’s four asserted patents.
