Defender Screens v. Fenetex: MagForce Screen Track Patent Suit Dismissed Without Prejudice
Defender Screens International, LLC filed a patent infringement action against Fenetex Corporation in the Florida Middle District Court, asserting two patents covering the MagForce Screen Track System. The case closed without prejudice just 133 days after filing — leaving the door open for future enforcement action.
Screen track patent clash ends before defendant even answered
Defender Screens International, LLC filed suit against Fenetex Corporation on June 14, 2024, in the U.S. District Court for the Middle District of Florida, asserting infringement of US9719292B1 and US10036198B2 — two patents covering retractable screen track technology commercialised as the MagForce Screen Track System. The action placed two direct competitors in the retractable screen and shading market on a litigation footing with potential implications for product design freedom across the sector.
On October 25, 2024 — just 133 days after filing — Defender Screens filed a Notice of Dismissal Without Prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because no answer or motion for summary judgment had been filed by Fenetex, dismissal was available as of right. The Court directed the Clerk to terminate all pending motions and close the case. Critically, a dismissal without prejudice does not adjudicate the merits and does not bar Defender Screens from refiling the same claims.
The sub-133-day resolution is consistent with an early pre-answer exit, typically driven by settlement discussions, a licensing agreement, or a strategic reassessment of claim strength. The public record is silent on whether any commercial arrangement was reached between the parties. Because no answer was filed, no invalidity counterclaims were placed on record, and the patents remain unimpaired in terms of their enforceability against Fenetex or any other market participant.

Dismissed without prejudice: what Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s right to dismiss before answer
Federal Rule of Civil Procedure 41(a)(1)(A)(i) permits a plaintiff to voluntarily dismiss an action without a court order if the defendant has not yet served an answer or a motion for summary judgment. Here, Fenetex had not answered, so Defender Screens exercised that right unilaterally. The dismissal takes effect on filing and does not require judicial approval — the Court’s order simply directed the Clerk to close the docket.
Voluntary — no merits adjudicationWithout prejudice: the case can return
A dismissal without prejudice leaves the plaintiff’s claims legally intact. Defender Screens may refile the same infringement allegations against Fenetex — subject to the applicable statute of limitations — in any competent court. This contrasts with a dismissal with prejudice, which would operate as a final judgment on the merits. The public record does not disclose whether any settlement or licensing agreement was reached, meaning the litigation risk for Fenetex has not been formally extinguished.
Claims survive — refiling possiblePatents US9719292B1 and US10036198B2 remain fully enforceable
Because the case was dismissed before any substantive proceedings, no invalidity rulings, claim construction orders, or adverse findings were issued. Both asserted patents retain their presumption of validity under 35 U.S.C. § 282. Defender Screens preserves its ability to assert these patents against Fenetex or other competitors without any estoppel risk arising from this litigation.
Patents unimpairedSector uncertainty persists around MagForce Screen Track IP
For competitors and channel partners in the retractable screen and exterior shading market, the without-prejudice dismissal resolves nothing substantively. The scope and validity of the MagForce Screen Track patents has not been tested judicially. Any manufacturer or distributor whose products incorporate similar screen track mechanics should treat both patents as live enforcement risk and consider formal FTO analysis before proceeding with product development or commercial expansion.

Official order — verbatim text
The Court’s order is purely administrative, directed by the plaintiff’s Rule 41(a)(1)(A)(i) notice rather than any judicial merits determination. The phrase ‘without prejudice’ is legally significant: it confirms that no res judicata bar attaches and the asserted patents were not adjudicated. For Defender Screens, both US9719292B1 and US10036198B2 emerge from this docket unscathed. For Fenetex, the order closes the immediate proceeding but does not extinguish the litigation risk.
US9719292B1 & US10036198B2 — MagForce retractable screen track system
US9719292B1 (Application No. US15/227345) and US10036198B2 (Application No. US15/646223) both protect innovations in retractable screen track systems, commercialised by Defender Screens as the MagForce Screen Track System. These patents cover the structural and mechanical architecture enabling retractable screens — such as insect, solar, and storm screens — to align, retain, and deploy reliably within a track system. The sequential application numbers suggest a continuation or improvement relationship, with the second patent building on the technical foundation of the first.
In the retractable screen and exterior shading market, screen track design is a key differentiator affecting installation speed, product durability, and end-user performance. Patents covering track alignment and retention mechanisms can create meaningful barriers to competing product designs. Fenetex, as a direct competitor in the motorised and retractable screen space, would face significant design-around challenges if these patents were litigated to a claim construction ruling — which makes the unresolved status of this dispute a continuing commercial concern for the broader sector.
Should you run an FTO against US9719292B1 and US10036198B2?
Any manufacturer, OEM, or distributor involved in designing or selling retractable screen systems — particularly those incorporating magnetic track alignment, retention clips, or similar mechanical engagement features — should assess exposure to these two patents before product launch or expansion into the U.S. market. The without-prejudice dismissal means Defender Screens retains full enforcement rights, and neither patent has been narrowed or invalidated by judicial proceedings.
PatSnap Eureka’s FTO Search Agent can map the claim scope of US9719292B1 and US10036198B2 against your product architecture, flag design-around opportunities, and surface prior art relevant to validity. Given that both patents share a common commercial embodiment in the MagForce system, a combined claim analysis is advisable to identify overlap and assess the cumulative risk profile before committing to a product roadmap in this space.

What this case signals for the retractable screen IP landscape
A pre-answer dismissal without prejudice rarely signals the end of a dispute — it often marks a strategic pause.
Pre-answer exit preserves maximum optionality for Defender Screens
By dismissing under Rule 41(a)(1)(A)(i) before Fenetex answered, Defender Screens avoided the risk of invalidity counterclaims entering the public record. Both patents remain pristine from an enforceability standpoint. This move is consistent with a plaintiff who has achieved a commercial objective — or who is repositioning before a stronger refile.
Fenetex faces unresolved exposure on two screen track patents
Without a covenant not to sue or a confirmed licence, Fenetex remains exposed to re-litigation. The absence of any defendant agent or law firm on record suggests Fenetex may not have fully engaged litigation counsel, which could indicate the matter was resolved through business-level dialogue rather than formal legal proceedings.
Defender v Fenetex — key questions answered
The case was dismissed without prejudice under Rule 41(a)(1)(A)(i), meaning no merits ruling was issued. Defender Screens may refile the same claims against Fenetex. Both asserted patents — US9719292B1 and US10036198B2 — remain valid and enforceable, and no invalidity findings were made.
Defender Screens asserted US9719292B1 (App. No. US15/227345) and US10036198B2 (App. No. US15/646223), both covering retractable screen track system technology commercialised as the MagForce Screen Track System.
Yes. A dismissal without prejudice does not bar refiling. Defender Screens may assert the same patents in a new action subject to the applicable six-year damages limitations period under 35 U.S.C. § 286. No covenant not to sue or licence has been publicly disclosed.
The case closed in 133 days, before Fenetex filed an answer. Such rapid pre-answer dismissals are typically consistent with a negotiated resolution — such as a licensing agreement or settlement — or a strategic decision to refile in a different forum. The public record does not disclose the underlying commercial reason.
The MagForce Screen Track System is Defender Screens’ commercial retractable screen product, protected by US9719292B1 and US10036198B2. The patents cover track alignment and retention mechanisms central to the system’s design. Fenetex, a competitor in the motorised retractable screen market, was alleged to infringe these mechanisms — though the case was dismissed before any infringement finding.
