Fecon v. Tennessee Valley Equipment: Mulcher Teeth Patent Infringement Dismissed
Fecon, LLC brought a five-patent infringement action against Tennessee Valley Equipment LLC over replacement teeth for mulching equipment, including V-Back design teeth. The plaintiff voluntarily dismissed the case without prejudice after just 90 days — before the defendant filed any answer — leaving the door open for future enforcement.
Five-patent mulcher tooth dispute exits court in 90 days flat
Fecon, LLC — a manufacturer of forestry and land-clearing equipment — filed suit against Tennessee Valley Equipment LLC in the Middle District of Tennessee on June 13, 2025, asserting infringement of five patents: utility patents US9943037B2, US10201130B2, and US10806094B2, plus design patents USD0791195S and USD0757124S. The asserted products were replacement teeth for mulching machines, specifically including V-Back design teeth intended to substitute for genuine Fecon V-Back teeth.
On September 11, 2025, Fecon filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i), and the court entered an order dismissing the action without prejudice the same day. Because Tennessee Valley Equipment had not yet filed an answer or a motion for summary judgment, the dismissal was effective as a matter of right — no court approval or opposing consent was required. No costs or attorneys’ fees were awarded to either side.
A 90-day lifecycle is atypically short for a multi-patent district court infringement action and suggests the parties may have reached a private resolution — licensing, a cease-and-desist compliance, or a business agreement — though the public record is entirely silent on any such terms. Alternatively, Fecon may have strategically preserved its claims for refiling in a different venue or at a later date. The without-prejudice posture means all five patents remain enforceable and the same claims could be reasserted against Tennessee Valley Equipment or other aftermarket tooth suppliers.

90-day lifespan — well below the median district court patent case duration of 2+ years
Voluntarily dismissed: what the without-prejudice exit means for both parties
Rule 41(a)(1)(A)(i): a dismissal as of right
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the opposing party serves an answer or a motion for summary judgment. Because Tennessee Valley Equipment had filed neither, Fecon’s notice was self-executing. The court’s order was confirmatory, not dispositive — the dismissal took effect upon filing of the notice itself.
No court approval requiredWithout prejudice — but what does that mean here?
A without-prejudice dismissal extinguishes this particular action but preserves the plaintiff’s right to refile the same claims against the same defendant in the future. The public record does not disclose whether any settlement, licensing agreement, or other commercial arrangement underlies the dismissal. Practitioners should not assume settlement occurred — voluntary dismissal without prejudice is equally consistent with a strategic withdrawal, a venue change, or an ongoing negotiation.
Refiling rights preservedTennessee Valley Equipment faces no judgment — but exposure persists
The dismissal delivers no merits ruling in the defendant’s favour. Tennessee Valley Equipment faces no injunction, no damages award, and no fee order. However, because the dismissal is without prejudice, Fecon retains the right to refile on any or all five patents. The defendant’s aftermarket V-Back tooth products remain subject to potential future infringement claims unless a private resolution or design-around has been implemented.
No judgment; future risk remainsAftermarket mulcher tooth suppliers should monitor Fecon’s patent portfolio
This case signals that Fecon actively monitors and enforces its mulcher tooth IP — spanning both utility and ornamental design registrations — against aftermarket suppliers. The swift exit before any answer suggests a private resolution may have been reached, but the five asserted patents remain valid and enforceable. Other suppliers of replacement mulcher teeth, particularly those marketing V-Back or geometrically similar designs, should treat this filing as a credible enforcement signal.

Official order — verbatim text
The court’s order confirms a textbook Rule 41(a)(1)(A)(i) voluntary dismissal: because the defendant had not yet answered or moved for summary judgment, the plaintiff held an absolute right to dismiss. The court made no merits findings on any of the five asserted patents. The without-prejudice designation means the dismissal carries no res judicata effect — Fecon’s infringement claims remain live. The absence of any cost or fee award is consistent with this procedural posture; no exceptional-case finding under 35 U.S.C. § 285 was triggered.
US9943037B2 — Mulcher tooth retention and cutting geometry
The five asserted patents cover both the functional and ornamental aspects of replacement teeth used in forestry mulching machines — equipment that grinds trees, brush, and stumps into mulch. US9943037B2, US10201130B2, and US10806094B2 are utility patents protecting cutting geometry, tooth retention systems, and related structural configurations. USD0791195S and USD0757124S are design patents protecting the ornamental appearance of specific tooth profiles, including the V-Back shape that is commercially central to Fecon’s product line.
Fecon’s multi-patent strategy — layering utility protection over functional innovations with design patent coverage of the visual form — is characteristic of OEM manufacturers defending against aftermarket commoditisation. Replacement teeth are a high-frequency consumable in forestry and land-clearing operations, making the aftermarket commercially significant. For any supplier manufacturing or distributing geometrically similar replacement teeth, all five patents represent active infringement risk, particularly given that Fecon has now demonstrated willingness to litigate in its regional home court.
Should you run an FTO against Fecon’s mulcher tooth patent portfolio?
Any company manufacturing, importing, or distributing replacement cutting teeth for forestry mulchers — especially V-Back or geometrically similar profiles — should treat this case as a trigger for formal freedom-to-operate analysis. The combination of utility and design patent claims means a product can clear functional claim limitations and still infringe the registered design. Regional equipment dealers and OEM tooth suppliers are the most exposed; distributors sourcing from overseas manufacturers should also verify the upstream patent clearance status of their supply chain.
PatSnap Eureka’s FTO Search Agent can map each of the five asserted patents against your product specifications, identify relevant prior art that may support invalidity arguments, and flag any continuation or divisional applications in Fecon’s prosecution history that could extend coverage. Eureka’s claim-chart automation accelerates the analysis across both utility and design patent families, giving your legal and product teams a structured risk register before you commit to inventory or distribution agreements.

What this case signals for the forestry equipment IP landscape
Fecon’s willingness to file — and quickly exit — a five-patent action reveals an enforcement strategy worth watching across the aftermarket mulching equipment sector.
Fecon’s portfolio spans both utility and design — a dual-threat enforcement position
Asserting three utility patents alongside two design patents in a single action is strategically significant. Design patents (USD0791195S, USD0757124S) offer comparatively fast, low-cost enforcement routes with strong damages potential under 35 U.S.C. § 289. Competitors offering visually similar replacement teeth face infringement risk even if they engineer around the utility claims.
A 90-day voluntary dismissal typically signals private resolution or strategic repositioning
Cases filed and dismissed before an answer is served frequently reflect cease-and-desist compliance, confidential licensing, or a calculated venue/timing strategy. IP teams at aftermarket equipment suppliers should assess whether Fecon is systematically targeting distributors, and whether similar notices of suit have been filed against other regional dealers.
Fecon v Tennessee — key questions answered
Fecon asserted five patents: utility patents US9943037B2, US10201130B2, and US10806094B2, plus design patents USD0791195S and USD0757124S. All relate to replacement cutting teeth for forestry mulching machines, including the V-Back tooth profile.
Fecon filed a notice of voluntary dismissal under Rule 41(a)(1)(A)(i) before Tennessee Valley Equipment had answered or moved for summary judgment. This gave Fecon an absolute right to dismiss. The court confirmed the dismissal without prejudice on September 11, 2025. The public record does not disclose whether any settlement or licensing agreement underlies the dismissal.
No. A without-prejudice dismissal explicitly preserves Fecon’s right to refile the same claims. All five asserted patents remain valid and enforceable, and Fecon may bring a new action in any appropriate venue. The dismissal carries no res judicata effect.
Design patents protect the ornamental appearance of a product. Under the Egyptian Goddess standard, infringement is assessed from the perspective of an ordinary observer — a plaintiff-friendly test. Damages under 35 U.S.C. § 289 can reach the infringer’s total profit on the infringing article. For aftermarket mulcher tooth suppliers, design patent exposure can be significant even where utility claims are designed around.
The case lasted 90 days from filing (June 13, 2025) to dismissal (September 11, 2025). This is well below the median patent case lifecycle. Such a short duration before any responsive pleading typically suggests the parties reached a private resolution — such as a licensing agreement or a commitment to cease infringing activity — though the public record does not confirm this.
