Microtech Knives v. Gunner Gear: OTF Knife Patent Dispute Settled in 140 Days
Microtech Knives, Inc. filed a patent infringement action against Gunner Gear, LLC in the Middle District of Florida, asserting US11607818B1 covering the Silverback out-the-front knife. The case was resolved by settlement and administratively closed just 140 days after filing — well before any merits ruling.
A swift settlement ends Microtech’s OTF knife IP dispute with Gunner Gear
On 29 May 2024, Microtech Knives, Inc. — a premium tactical knife manufacturer — filed suit against Gunner Gear, LLC in the U.S. District Court for the Middle District of Florida, alleging infringement of US11607818B1, a patent protecting the Silverback out-the-front (OTF) knife. The accused product was identified as the Silverback and Silverback OTF Knife sold or distributed by Gunner Gear.
The parties advised the Court on 16 October 2024 that the matter had been settled. Pursuant to Local Rule 3.09(b) of the Middle District of Florida, the case was administratively closed and dismissed without prejudice, with a 60-day window for the parties to file a stipulated final order or judgment. No such order appears on the public docket, suggesting the settlement resolved the matter within that window or the parties allowed the administrative closure to stand.
A resolution in approximately 140 days — before any Markman hearing or substantive motion practice — is consistent with a commercial settlement reached shortly after service, likely driven by licensing considerations or a negotiated cease-and-desist arrangement. The without-prejudice dismissal means Microtech retains the ability to re-file if any agreed terms are breached, though the specific conditions of the settlement remain confidential and outside the public record.
Filing to Dismissed without Prejudice in 140 days
140 days from filing to closure — faster than the typical 2–3 year district court patent lifecycle
Settled and dismissed without prejudice: what this means for both parties
Administrative closure under Local Rule 3.09(b) explained
When parties in the Middle District of Florida notify the Court of a settlement, Local Rule 3.09(b) allows the case to be administratively closed pending a stipulated final order. If none is filed within 60 days, the case is dismissed without prejudice by default. This is a procedural housekeeping measure — it does not constitute a merits ruling and does not bar future litigation on the same claims.
Procedural closure, no merits rulingWithout prejudice: the right to re-file preserved
A dismissal without prejudice means Microtech Knives retains the right to refile the infringement claim if circumstances warrant — for example, if Gunner Gear breaches any agreed licensing or cease-and-desist terms. It does not extinguish the patent or the cause of action. The public record does not disclose whether the parties reached a licence, a design-around agreement, or simply a mutual walk-away.
Re-filing right preservedMicrotech preserves patent rights and enforcement leverage
By settling without a prejudicial dismissal, Microtech Knives maintains the enforceability of US11607818B1 and avoids any adverse claim-construction precedent. The swift resolution — 140 days — suggests Microtech achieved its commercial objective, whether monetary or injunctive, without the cost and uncertainty of a full trial. The patent remains an active enforcement asset against other potential infringers.
Patent remains enforceableGunner Gear exits without a public liability finding
Gunner Gear avoided a public infringement judgment, preserving its commercial reputation. The without-prejudice nature of the dismissal means any settlement terms — product modifications, licence fees, or sales restrictions — were negotiated privately. However, the existence of the litigation and the patent itself are now publicly indexed, raising the IP risk profile for any party operating in the OTF knife market.

Official order — verbatim text
The Court’s order confirms settlement via party notification rather than a merits determination — no claim construction, infringement finding, or damages assessment was made. The 60-day window language in the order is standard Middle District of Florida administrative closure procedure. The without-prejudice qualifier means the patent holder retains full enforcement rights, and the case does not create any estoppel or res judicata bar against future actions involving US11607818B1.
US11607818B1 — Silverback out-the-front knife mechanism
US11607818B1, filed under application number US17/819763, protects the Silverback OTF (out-the-front) knife — a class of automatic knives where the blade deploys and retracts linearly through the front of the handle. Utility patents in this space typically protect actuation mechanisms, blade-locking geometry, and handle-integrated trigger systems. As a B1 grant (no prior publication), the patent issued directly from examination without a published application, limiting early public visibility of its claim scope.
For the premium tactical knife market, a utility patent on an OTF mechanism is a high-value defensive and offensive asset. Microtech Knives commands a premium brand position in the OTF segment, and patents of this type are designed to prevent lower-cost competitors from replicating the mechanical architecture of flagship products. Any competitor — whether a manufacturer, importer, or distributor — whose OTF knife employs a similar deployment mechanism faces non-trivial infringement exposure until a thorough claim analysis has been completed.
Should you run an FTO analysis against US11607818B1?
If your organisation designs, imports, distributes, or retails out-the-front automatic knives — particularly products marketed with Silverback-style actuation mechanisms — US11607818B1 represents a live enforcement risk. This case confirms that Microtech Knives will pursue distributors, not just manufacturers. R&D teams developing OTF knife products and procurement teams sourcing from third-party OTF suppliers should both treat this patent as a priority FTO target.
PatSnap Eureka’s FTO Search Agent can map the claim language of US11607818B1 against your product specifications, identify prior art that may constrain claim scope, and flag related continuation or divisional applications in the Microtech portfolio that could represent additional exposure. Early-stage FTO analysis is significantly cheaper than defending a Middle District of Florida infringement action.

What this case signals for the tactical knife and OTF knife IP landscape
Microtech’s swift enforcement action signals active patent policing in the premium OTF knife segment.
Premium knife brands are actively enforcing utility patents on mechanism design
US11607818B1 covers the Silverback OTF mechanism — a utility patent, not merely a design registration. This signals that Microtech is investing in broad IP protection over functional knife deployment mechanisms, raising the bar for competitors seeking to enter the OTF segment with similar slide or trigger actuation designs.
Early settlement before claim construction limits public IP intelligence
Cases resolved before a Markman hearing leave claim scope undefined in the public record. Competitors and FTO analysts cannot rely on judicial claim construction to understand the patent’s boundaries. An independent claim-by-claim analysis of US11607818B1 is essential for any OTF knife product team before market entry.
Microtech v Gunner — key questions answered
Microtech Knives asserted US11607818B1, a utility patent protecting the Silverback OTF (out-the-front) knife mechanism. The accused products were identified as the Silverback and Silverback OTF Knife distributed by Gunner Gear, LLC.
The case was administratively closed under M.D. Florida Local Rule 3.09(b) after the parties reported a settlement, then dismissed without prejudice. Without prejudice means Microtech retains the right to refile the infringement claim. No merits ruling was made and no adverse judgment was entered against either party.
The case lasted 140 days, from filing on 29 May 2024 to administrative closure on 16 October 2024. This is significantly shorter than the average U.S. patent litigation timeline, consistent with an early commercial settlement reached before any substantive motion practice.
No. A settlement and without-prejudice dismissal do not affect the validity or enforceability of US11607818B1. The patent remains active and Microtech retains full rights to enforce it against other parties. No claim construction or invalidity ruling was issued in this case.
The Silverback is a premium out-the-front automatic knife in Microtech’s lineup. US11607818B1 protects its mechanical deployment architecture. Because the patent covers functional mechanism elements rather than purely aesthetic design, it potentially reaches any OTF knife with a sufficiently similar actuation system — making it relevant to manufacturers, importers, and distributors across the tactical knife segment.
