Omnitek Partners v. Rafael U.S.A.: Spike Missile Guidance Patent Dismissed Without Prejudice
Omnitek Partners, LLC asserted US8686325B2 — a patent covering guidance of gun-fired or mortared rounds toward an intended target — against Rafael U.S.A.’s Spike NLOS missile system. Filed in the District of Maryland in August 2024, the case closed just 142 days later via voluntary dismissal without prejudice, leaving Omnitek’s enforcement rights intact.
Early voluntary exit preserves Omnitek’s patent enforcement options against Rafael
On 13 August 2024, Omnitek Partners, LLC filed a patent infringement action against Rafael U.S.A., Inc. in the U.S. District Court for the District of Maryland, assigned to Judge Richard D. Bennett. The complaint centred on US8686325B2, a patent directed to guidance technology for gun-fired or mortared rounds, which Omnitek alleged was practised by Rafael’s Spike NLOS missile system — a precision-guided munition designed to engage targets beyond line of sight.
The case terminated on 2 January 2025 when Omnitek filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i), expressly stating the dismissal was without prejudice as to the asserted patent. Because Rafael had not yet answered the complaint or filed a motion for summary judgment, Omnitek was entitled to dismiss unilaterally as of right, requiring no court order and imposing no merits ruling on either party.
The 142-day duration and pre-answer exit suggest the parties may have reached an understanding — whether commercial, licensing, or strategic — outside the formal record, though the public docket does not disclose any settlement terms. Alternatively, Omnitek may be repositioning for refiling in a different venue or reformulating its infringement contentions. The without-prejudice designation means the patent remains fully enforceable and the door to future litigation against Rafael U.S.A. remains open.
Filing to Voluntary dismissal in 142 days
142 days — resolved before defendant answered or moved for summary judgment
Voluntary dismissal without prejudice: what the exit terms mean for both parties
Rule 41(a)(1)(A)(i): a dismissal as of right, no court approval needed
Federal Rule 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order at any time before the defendant serves an answer or a motion for summary judgment. Omnitek filed precisely at this window. The result is a clean procedural exit: no merits adjudication, no judgment on the record, and no obligation to explain the strategic rationale to the court or the public.
Pre-answer voluntary dismissalWithout prejudice: the patent claim survives this dismissal entirely
Omnitek explicitly designated the dismissal as without prejudice as to the asserted patent. This means no claim preclusion attaches: Omnitek may refile an infringement action based on US8686325B2 against Rafael U.S.A. — or other defendants — in the same or a different court. A with-prejudice dismissal would have extinguished those rights; this dismissal does not. The public record does not disclose whether any side agreement accompanied this filing.
Enforcement rights preservedRafael exits without a merits win — but faces ongoing exposure
Rafael U.S.A. obtains no judgment in its favour and cannot invoke res judicata or collateral estoppel against Omnitek on the basis of this dismissal. The Spike NLOS product remains potentially exposed to a refiled infringement claim under US8686325B2. Rafael has not obtained any ruling on invalidity, non-infringement, or claim construction that could be used defensively in future proceedings.
No defensive judgment securedDefence-sector IP enforcement: guided munitions patents carry long tail risk
Precision-guided munitions technology sits at the intersection of defence procurement and commercial IP enforcement. A without-prejudice exit in this sector typically signals ongoing licensing discussions or a tactical repositioning rather than a concession. Competitors and primes supplying guided round or missile guidance systems should note that US8686325B2 remains active and that Omnitek has demonstrated willingness to litigate in federal court.

Official order — verbatim text
The dismissal notice expressly invokes Rule 41(a)(1)(A)(i) and designates the exit as without prejudice ‘as to the asserted patent.’ This phrasing is deliberate: by tying the without-prejudice designation directly to US8686325B2, Omnitek signals that the patent remains the operative enforcement instrument. No claim construction, no invalidity finding, and no non-infringement determination issued — meaning neither party carries any issue-preclusive finding into future proceedings. The absence of any defendant filing also means no fee-shifting analysis under 35 U.S.C. § 285 was triggered.
US8686325B2 — Guided gun-fired and mortared round homing technology
US8686325B2, filed under application number US13/069313, covers technology for guiding a gun-fired or mortared round toward an intended target — the core technical capability underlying precision-guided munitions that bridge conventional artillery and smart-weapon performance. The patent sits within the electro-optical and terminal guidance domain, a rapidly growing area as defence procurement shifts toward cost-effective precision solutions at the squad and battery level.
Strategically, this patent is significant because it potentially covers a broad class of guided munitions platforms, not a single product. As defence contractors, Tier 1 primes, and allied-nation licensees expand their guided round portfolios, the claims of US8686325B2 could intersect with multiple programmes simultaneously. Omnitek’s decision to assert against the Spike NLOS — a high-profile, internationally deployed precision missile — suggests the patent holder views the claim scope as commercially material and enforcement-ready.
Should you run an FTO analysis against US8686325B2?
Any organisation developing, manufacturing, integrating, or procuring gun-launched or mortar-launched guided munitions — including course-correcting fuzes, loitering munitions adapted from artillery platforms, and hybrid guided round systems — should assess clearance against US8686325B2. The fact that Omnitek pursued a major defence firm like Rafael U.S.A. in federal court demonstrates active enforcement intent, and the without-prejudice dismissal means that intent has not been abandoned.
PatSnap Eureka’s FTO Search Agent can map the independent and dependent claims of US8686325B2 against your specific product architecture, identify prior art that may affect claim validity, and surface related family members or continuation applications that could extend the patent’s reach. For defence-sector product and legal teams operating under procurement timelines, early FTO clearance is substantially less costly than reactive litigation response.

What this case signals for the guided munitions and defence IP landscape
A pre-answer voluntary dismissal without prejudice in a defence technology case rarely signals the end of enforcement — it often signals a reset.
Without-prejudice exits preserve full optionality for patent holders
Omnitek’s use of Rule 41(a)(1)(A)(i) before Rafael answered means no claim preclusion, no adverse judgment, and no fee-shifting risk. For IP licensing entities, this is a low-cost tactical retreat that keeps every enforcement avenue open. Companies that receive such a dismissal notice should not treat it as a win — the clock may simply be restarting.
Defence primes and missile system suppliers should audit US8686325B2 exposure now
The Spike NLOS is one of several precision-guided munitions platforms that could plausibly intersect with guided-round homing technology claimed in US8686325B2. Any OEM, integrator, or licensee working on gun-launched or mortar-launched guided munitions should assess whether their products fall within the patent’s claim scope before a refiled action arrives.
Omnitek v Rafael — key questions answered
It means Omnitek filed a notice under Rule 41(a)(1)(A)(i) ending the case before Rafael answered, with an express without-prejudice designation. No merits ruling issued. Omnitek retains full rights to refile an infringement action based on US8686325B2 against Rafael U.S.A. or other defendants in the future.
US8686325B2, filed as application US13/069313, directed to guidance technology for gun-fired or mortared rounds homing toward an intended target. Omnitek alleged this patent was practised by Rafael’s Spike NLOS missile system.
Yes. Because the dismissal was without prejudice and entered before Rafael filed any responsive pleading, no claim preclusion attaches. Omnitek may refile the same infringement claims based on US8686325B2 in the District of Maryland or another federal court, subject to any applicable statute of limitations.
No. Rafael obtained no judgment on the merits. The case was dismissed by Omnitek’s own notice before Rafael answered. Rafael cannot rely on any finding of non-infringement or invalidity from this proceeding in future litigation involving US8686325B2.
The Spike NLOS (Non-Line-Of-Sight) is a precision-guided missile system developed by Rafael Advanced Defense Systems, capable of engaging targets beyond visual range. Omnitek alleged that its guidance mechanisms — specifically those directing a projectile toward an intended target — fell within the claims of US8686325B2, which covers guidance technology for gun-fired or mortared rounds.
