Omnitek Partners v. Lockheed Martin: Patent Suit Over THAAD Dismissed With Prejudice
Omnitek Partners, LLC filed suit in the Eastern District of Texas asserting US6860448B2 against Lockheed Martin’s THAAD missile defense system, PAC-3 CRI, PAC-3 MSE, and THAAD ER Interceptor. The case ended 223 days later when Omnitek voluntarily dismissed all claims with prejudice — before Lockheed Martin even filed an appearance.
A pre-answer dismissal with prejudice: Omnitek exits cleanly — but permanently
On March 1, 2024, Omnitek Partners, LLC filed a patent infringement action against Lockheed Martin Corporation in the Eastern District of Texas (Case No. 5:24-cv-00031), asserting US6860448B2 against a portfolio of advanced missile defense products: the THAAD Missile Defense System, PAC-3 CRI, PAC-3 MSE, and THAAD ER Interceptor. Omnitek was represented by William P. Ramey III of Ramey LLP — a firm with an active patent assertion practice in the Eastern District.
On October 10, 2024, Judge Robert W. Schroeder III accepted Omnitek’s Notice of Voluntary Dismissal filed pursuant to Rule 41(a)(1)(A)(i), dismissing all claims against Lockheed Martin with prejudice. Critically, Lockheed Martin had not appeared, answered, or served any responsive pleading at the time of dismissal. The court confirmed that all relief not previously granted was denied and directed the clerk to close the action.
The 223-day timeline — ending before the defendant even formally appeared — is consistent with a pre-litigation settlement or strategic withdrawal. Dismissal with prejudice, however, is the more consequential element: Omnitek is permanently barred from re-filing the same patent claims against Lockheed Martin. The public record does not disclose whether any commercial agreement accompanied the dismissal, leaving the true resolution terms unknown.

Dismissed with prejudice: what the voluntary exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s right to exit before answer
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss without a court order if the defendant has not yet served an answer or motion for summary judgment. Here, Omnitek exercised that right — but chose to dismiss with prejudice, a stricter outcome than the rule requires by default. The court accepted the notice and entered a formal order closing the case.
Rule 41(a)(1)(A)(i) dismissalWith prejudice: Omnitek cannot refile these claims against Lockheed
A dismissal with prejudice carries full res judicata effect — Omnitek Partners is permanently barred from asserting the same patent claims in US6860448B2 against Lockheed Martin on these products. This is materially different from a dismissal without prejudice, which would preserve the right to refile. The choice of ‘with prejudice’ here suggests either a negotiated resolution or a deliberate decision to permanently close out this specific avenue of enforcement.
Permanent bar on refilingLockheed Martin exits without ever responding — and gains permanent protection
Lockheed Martin achieved a highly favourable result: the case was closed before it was required to file any response, incurring minimal litigation cost. More significantly, the with-prejudice designation means Lockheed faces no future exposure from Omnitek under US6860448B2 for THAAD, PAC-3 CRI, PAC-3 MSE, or THAAD ER. No invalidity finding was required — Lockheed’s protection derives entirely from the preclusive effect of the dismissal.
Lockheed fully protectedPre-answer resolution signals probable out-of-court agreement
Cases involving large defense contractors rarely resolve through unilateral plaintiff withdrawal without any benefit to the plaintiff. The with-prejudice nature of the dismissal, combined with the absence of any court-ordered costs or sanctions, is consistent with a private licensing or settlement agreement. Competitors and IP practitioners monitoring Omnitek’s assertion strategy should note that US6860448B2 may still be enforceable against other missile defense or guidance technology manufacturers.

Official order — verbatim text
The court’s order tracks the precise language of Rule 41(a)(1)(A)(i), confirming that Lockheed Martin had not appeared or filed any responsive pleading at the time of dismissal. The critical phrase is ‘dismissed with prejudice’ — this is not the Rule 41 default, which is without prejudice when the defendant has not answered. Omnitek’s explicit election of prejudicial dismissal extinguishes its right to re-litigate US6860448B2 against Lockheed Martin, and the court’s denial of all ungranted relief closes the record completely.
US6860448B2 — missile guidance and defense system technology
US6860448B2 (application number US10/236004) is the sole patent asserted in this action. Filed under a US10/236 application series, it covers technology in the missile defense and guidance domain. Omnitek asserted it against four distinct Lockheed Martin products: the THAAD Missile Defense System, PAC-3 CRI, PAC-3 MSE, and THAAD ER Interceptor — suggesting the claims are broad enough to reach multiple interceptor platforms across different product generations.
The breadth of products accused — spanning THAAD’s terminal-phase interceptors and multiple PAC-3 variants — suggests the patent may relate to guidance, propulsion control, or interceptor system architecture rather than a narrow component feature. For competitors and suppliers in the missile defense supply chain, US6860448B2 remains an active enforcement risk: the dismissal with prejudice only bars Omnitek from suing Lockheed Martin, not other manufacturers or integrators working on comparable interceptor technology.
Should you run an FTO against US6860448B2?
Any company involved in missile defense systems, terminal-phase interceptors, or aerospace guidance technology should treat US6860448B2 as an active risk. The patent was asserted against THAAD and PAC-3 products — two of the most widely deployed interceptor platforms in US and allied defense systems. If your organisation designs, manufactures, or integrates components for comparable systems, the absence of a Lockheed Martin judgment does not reduce your exposure.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map US6860448B2’s claim scope against current product architectures in minutes. Eureka identifies overlapping claim language, surfaces relevant prior art that could support invalidity arguments, and flags related patents in Omnitek’s portfolio — giving your team a defensible FTO position before any demand letter arrives.

What this case signals for the defense and aerospace IP landscape
A pre-answer dismissal with prejudice against a major defense contractor raises questions about assertion strategy and licensing leverage in the missile defense sector.
With-prejudice dismissals protect defendants — but only from that specific plaintiff
Lockheed Martin is permanently shielded from Omnitek’s claims under US6860448B2, but other parties holding similar patents face no such bar. Defense contractors operating THAAD-related technology should assess residual exposure from third-party patent holders in missile guidance and interception systems.
Ramey LLP’s Eastern District playbook: file, negotiate, exit on terms
Ramey LLP is a repeat filer in the Eastern District of Texas. Cases that close before the defendant appears — particularly with prejudice — frequently suggest a pre-litigation resolution. IP teams facing Ramey LLP filings should assess early settlement economics against the cost of full district court litigation.
Omnitek v Lockheed — key questions answered
Dismissed with prejudice means Omnitek Partners, LLC is permanently barred from asserting the same patent claims under US6860448B2 against Lockheed Martin for the accused THAAD and PAC-3 products. Unlike a without-prejudice dismissal, Omnitek cannot refile the same action in any court.
The public record does not disclose the reason. However, dismissal with prejudice before the defendant has even appeared is consistent with a private resolution — such as a licensing agreement or settlement — where the plaintiff elects to formally close the case. No court-ordered payments or sanctions are recorded.
Omnitek Partners accused four Lockheed Martin products: the THAAD Missile Defense System, PAC-3 CRI, PAC-3 MSE, and THAAD ER Interceptor. All are advanced missile interceptor platforms used in US and allied ballistic missile defense systems.
No. A voluntary dismissal with prejudice resolves nothing about the patent’s validity or claim scope. US6860448B2 remains a granted US patent and can still be asserted against other parties. No claim construction, invalidity ruling, or infringement finding was issued in this case.
Omnitek Partners was represented by William P. Ramey III of Ramey LLP, a law firm with an active patent assertion practice in the Eastern District of Texas. No defendant counsel is recorded in the public case data, consistent with Lockheed Martin not having appeared before dismissal.
