Darton Archery v. Martin Outdoors: Compound Bow Patent Suit Dismissed After 375 Days
Darton Archery, LLC asserted two compound bow patents — US9121658B1 and US6990970B1 — against Martin Outdoors and Jeffersonville Georgia, LLC in Michigan federal court, targeting products including the Martin Legend 730 and Obsession Nitro Ghost bows. After 375 days, Darton voluntarily dismissed the complaint without prejudice, leaving the merits unresolved.
Compound Bow IP Clash Ends Without Merits Ruling in Michigan
On October 19, 2023, Darton Archery, LLC — a Michigan-based compound bow manufacturer — filed a patent infringement action in the U.S. District Court for the Eastern District of Michigan against Martin Outdoors, LLC and Jeffersonville Georgia, LLC. The complaint alleged infringement of two patents: US9121658B1 and US6990970B1, both covering compound bow technology. The accused products included the Martin Legend 730, Obsession Nitro Ghost, ANAXX 38, ANAXX 3D, MAXX 33, MTX 29, NTX 40, and NTX 8 compound bows.
The case closed on October 28, 2024, when Darton filed a voluntary dismissal notice under Federal Rule of Civil Procedure 41(a)(1)(A)(i), dismissing the complaint against Jeffersonville Georgia, LLC — identified as the last pending defendant — without prejudice and without costs or attorney fees. Because the dismissal was filed without specifying a settlement, the precise reason for withdrawal remains undisclosed in the public record.
The 375-day duration suggests the parties engaged in at least some preliminary litigation activity before resolution, though no trial or dispositive ruling was reached. The without-prejudice designation technically preserves Darton’s right to refile on the same patents, which may be strategically significant depending on whether a licensing arrangement was quietly reached. What drove the dismissal — and whether the accused products remain a commercial concern for Darton — cannot be determined from publicly available filings.
Filing to Voluntary dismissal in 375 days
375 days from filing to voluntary dismissal — consistent with pre-trial resolution before substantive rulings
Voluntarily dismissed: what this resolution means for both parties
Rule 41(a)(1)(A)(i) allows unilateral early dismissal
A plaintiff may voluntarily dismiss a case under Rule 41(a)(1)(A)(i) without a court order, provided it files before the defendant serves an answer or motion for summary judgment. This is a procedural exit — the court makes no ruling on the merits of the patents, infringement, or validity. The dismissal notice itself resolves the action and closes the docket.
No merits adjudicationWithout prejudice — but the public record is silent on cause
A dismissal ‘without prejudice’ means the plaintiff retains the legal right to refile the same claims in the future, subject to applicable statutes of limitations. A dismissal ‘with prejudice’ would permanently bar refiling. The dismissal notice in this case specifies ‘without prejudice,’ but the public docket does not disclose whether a confidential settlement, licensing agreement, or other arrangement underlies the withdrawal. Both interpretations remain legally plausible.
Refiling right preservedDarton retains its patents — enforceability unchanged
Because the case was voluntarily dismissed rather than decided on the merits, neither US9121658B1 nor US6990970B1 was subjected to a validity ruling. Darton’s patent rights are legally intact. The without-prejudice status means Darton could theoretically pursue enforcement against these or other defendants in the future, though strategic considerations and litigation costs typically inform that decision.
Patents remain enforceableMartin Outdoors exits without an infringement finding
No court ruled that the accused compound bows — including the Martin Legend 730, Obsession Nitro Ghost, or the ANAXX/NTX/MAXX product lines — infringe Darton’s patents. The defendants receive no formal legal protection from future suits on the same patents, however, as the dismissal without prejudice carries no claim-preclusive effect. Continued sale of the accused products could re-expose defendants to enforcement risk if Darton or a successor chooses to refile.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly resolves ‘the last pending claim,’ closing the docket entirely. The without-prejudice designation means no res judicata bar attaches — Darton could refile against these defendants or new parties on the same patents. The absence of any costs award to either side is notable and may be consistent with a negotiated resolution, though the public record does not confirm this. No claim construction, validity ruling, or infringement finding was issued, leaving the legal scope of both asserted patents formally undetermined.
US9121658B1 & US6990970B1 — Compound Bow Mechanism Patents
US9121658B1 (application no. US14/231872) and US6990970B1 (application no. US10/927764) are U.S. patents assigned to Darton Archery, LLC covering compound bow technology. US6990970B1, with its earlier application number, represents a foundational asset in Darton’s portfolio and likely covers core bow mechanics such as cam systems, draw weight, or limb geometry. US9121658B1 reflects a more recent generation of innovation in the same technical domain. Both patents were asserted against a broad range of accused products spanning multiple bow model lines.
For compound bow manufacturers and distributors, these patents represent a meaningful enforcement risk in a specialist but commercially active outdoor sporting goods sector. Darton is a longstanding U.S. bow maker and the assertion of both an earlier foundational patent and a later continuation-era patent against competitors’ flagship models — including the Obsession Nitro Ghost and Martin Legend 730 — suggests a deliberate strategy to protect core mechanical innovations across product generations. The absence of any invalidity ruling means both patents retain full presumptive validity.
Should you run an FTO against US9121658B1 and US6990970B1?
Any company designing, manufacturing, importing, or distributing compound bows — particularly those featuring cam systems, dual-cam draw mechanisms, or similar bow power delivery architectures — should conduct a freedom-to-operate analysis against both Darton patents before commercialising new products. The accused products in this case span a wide range of price points and configurations, suggesting Darton’s claim scope may be interpreted broadly. Distributors, not just manufacturers, were named as defendants in this action.

What this case signals for the compound bow IP landscape
A without-prejudice dismissal in a multi-product bow patent dispute leaves competitive and licensing questions unresolved for the archery sector.
Voluntary dismissal without prejudice signals unresolved competitive tension
When a patent holder withdraws without prejudice rather than settling with prejudice, it typically signals that the underlying IP dispute has not been permanently resolved. Competitors in the compound bow market should treat Darton’s two asserted patents as still-live enforcement assets, particularly if their products share design elements with the accused Martin Outdoors lineup.
No costs order preserves goodwill — consistent with a negotiated exit
The explicit ‘no costs or attorney fees’ provision in the dismissal notice is unusual for a purely unilateral withdrawal and may suggest the parties reached an informal understanding. However, absent a public settlement record, this interpretation is speculative. IP teams monitoring this space should watch for subsequent licensing disclosures or new filings involving the same patent numbers.
Darton v Martin — key questions answered
Darton Archery asserted two patents: US9121658B1 (application US14/231872) and US6990970B1 (application US10/927764), both covering compound bow technology. The accused products included the Martin Legend 730, Obsession Nitro Ghost, ANAXX 38, ANAXX 3D, MAXX 33, MTX 29, NTX 40, and NTX 8 compound bows.
Darton Archery voluntarily dismissed the case under Rule 41(a)(1)(A)(i) without prejudice. Without prejudice means no permanent bar to refiling — Darton retains the right to bring the same patent claims again in future. The public record does not disclose whether a settlement, license, or other arrangement was reached between the parties.
The defendants were Martin Outdoors, LLC and Jeffersonville Georgia, LLC. The inclusion of both parties suggests Darton targeted both the brand/manufacturer and a distributor entity, which is a notable dual-defendant enforcement strategy in this dispute.
No. Because the case was voluntarily dismissed before any substantive court ruling, neither US9121658B1 nor US6990970B1 was subjected to a validity determination, claim construction order, or infringement finding. Both patents retain their full presumptive validity under 35 U.S.C. § 282.
The accused products identified in the complaint included the Martin Legend 730, Obsession Nitro Ghost, ANAXX 38, ANAXX 3D, MAXX 33, MTX 29, NTX 40, and NTX 8 compound bows — a broad lineup spanning multiple product families associated with the defendants.
