Fractal Networks v. Movandi: Voluntary Dismissal After 61 Days
Fractal Networks LLC filed a patent infringement action against Movandi Corporation in the Delaware District Court, asserting US11189921B1 directed at cellular systems. The case closed just 61 days after filing when Fractal Networks voluntarily dismissed the action before Movandi had answered or moved for summary judgment.
Early voluntary exit before Movandi filed any response
On 1 April 2026, Fractal Networks LLC filed a patent infringement complaint against Movandi Corporation in the United States District Court for the District of Delaware (Case No. 1:26-cv-00359) before Judge John F. Murphy. The sole patent asserted was US11189921B1, relating to a cellular system, filed under application number US16/867368. Fractal Networks was represented by Brian E. Lutness of Silverman, McDonald & Friedman; Movandi by Anne Shea Gaza and Daniel G. Mackrides of Young Conaway Stargatt & Taylor, LLP.
The recorded Basis of Termination is 'Voluntary dismissal.' The docket order states that Fractal Networks filed a Notice of Voluntary Dismissal pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i), dismissing the action without prejudice, and explicitly noted that Movandi had not yet answered the complaint or moved for summary judgment. The case closed on 1 June 2026, 61 days after filing.
The dismissal occurred at the earliest procedural stage possible — before any substantive response from Movandi — which is notable given that Rule 41(a)(1)(A)(i) permits a plaintiff to dismiss as of right at exactly this pre-answer juncture. What drove the decision to withdraw at this stage is not disclosed in the available public record.

US11189921B1 — Cellular system patent asserted against Movandi
Any company developing, manufacturing, or commercialising cellular system products — particularly in 5G beamforming, antenna arrays, or wireless access infrastructure — should consider a freedom-to-operate analysis against US11189921B1. The patent was never challenged in this proceeding, its claim scope is judicially untested, and the without-prejudice dismissal leaves it available for reassertion. OEMs, chipset developers, and network equipment vendors are all potentially within scope.
Official order — verbatim text
The notice of voluntary dismissal invokes Rule 41(a)(1)(A)(i) and expressly records that Movandi had not answered or moved for summary judgment, confirming the dismissal was filed as of right. The docket states the dismissal is without prejudice. No merits determination — on infringement, validity, or claim scope — was reached, leaving US11189921B1 fully in force.
Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff's right to dismiss without leave
Federal Rule of Civil Procedure 41(a)(1)(A)(i) allows a plaintiff to dismiss an action as of right — without a court order — before the defendant has served an answer or a motion for summary judgment. Fractal Networks exercised this right exactly, as the notice expressly confirms Movandi had not yet answered. The dismissal is self-executing upon filing and requires no judicial approval.
Pre-answer dismissal as of rightWithout prejudice: the public record is silent on any restriction
The verdict text states the dismissal is 'without prejudice', meaning the action was not dismissed on the merits and Fractal Networks retains the theoretical ability to refile. However, the Basis of Termination is recorded simply as 'Voluntary dismissal' without specifying with or without prejudice. The specific terms — including any agreement between the parties — are not disclosed in the available record.
Refiling theoretically possibleMovandi exits without any merits ruling or admitted liability
Because the dismissal was filed before Movandi answered, the defendant incurred no formal adjudication of the infringement claim. No finding of liability, invalidity, or non-infringement was entered. Movandi is not bound by any judgment on the merits. The ongoing risk from US11189921B1 depends on whether Fractal Networks or a successor pursues the claim again.
No merits adjudicationPatent remains live; cellular system players should monitor US11189921B1
A without-prejudice dismissal leaves US11189921B1 fully enforceable. Companies operating in the 5G and cellular infrastructure space — particularly those developing beamforming or antenna array systems — face continued exposure from this patent. The swift exit before any claim construction or invalidity briefing means the patent's scope was never publicly tested in this proceeding.

R&D signals in the 5G cellular system and beamforming IP space
Forward-looking patent intelligence derived from Fractal Networks v. Movandi — covering portfolio activity, filing trends, and white-space opportunities in cellular system and 5G beamforming technology.
Fractal Networks' cellular patent portfolio and filing activity
Fractal Networks' assertion of US11189921B1 suggests a targeted IP portfolio in cellular system architecture. Monitoring the full patent family of US16/867368 — including any continuations, continuations-in-part, or divisional applications — reveals the breadth of claims available for future assertion against 5G infrastructure and device makers.
Portfolio filing activity5G beamforming patent filing trends around cellular system architecture
The cellular system space — encompassing massive MIMO, beamforming, and mmWave antenna arrays — is one of the most active filing domains in wireless technology. Understanding the density and ownership distribution of patents in this cluster helps identify which companies face the highest assertion risk and where technical white space exists for design-around strategies.
Filing density — 5G systemsMovandi Corporation's patent position in 5G beamforming solutions
Movandi's 5G beamforming chip and module technology places it at the centre of a competitive IP landscape. Assessing Movandi's own patent portfolio — including any defensive filings around beamforming IC architecture and mmWave front-end modules — provides a view of its capacity to cross-license or counter-assert in future disputes in this space.
Defensive IP — beamformingDesign-around space adjacent to US11189921B1's cellular system claims
Because US11189921B1's claim scope was never adjudicated in this proceeding, R&D teams should map the patent's claims against adjacent claim territory. Identifying under-patented approaches to cellular system architecture — particularly in distributed antenna systems, RAN virtualisation, and next-generation access nodes — may reveal design-around or innovation white-space opportunities.

What this case signals for the cellular/5G patent IP landscape
A pre-answer voluntary dismissal in a cellular patent case typically signals shifting strategy — and leaves the underlying patent fully available for redeployment.
US11189921B1 was never claim-constructed — scope remains untested
The case closed before any claim construction briefing, Markman hearing, or invalidity challenge was filed. This means the legal boundaries of US11189921B1 remain judicially undecided. Any company in the cellular system space should treat this patent as an active risk and conduct independent claim scope analysis.
Pre-answer dismissal limits defendant's ability to seek fee recovery
Because the case ended before Movandi answered, there is no adjudicated prevailing party. This procedural posture generally forecloses a standard 35 U.S.C. § 285 exceptional-case fee motion, meaning Movandi has limited avenues to recover defence costs from this proceeding. The specific terms of any side agreement are not disclosed in the record.
Fractal v Movandi — key questions answered
The case was voluntarily dismissed by Fractal Networks LLC. On 1 June 2026, Fractal Networks filed a Notice of Voluntary Dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i), dismissing the action without prejudice. The dismissal occurred 61 days after filing, before Movandi had answered the complaint or moved for summary judgment.
The sole patent asserted was US11189921B1, filed under application number US16/867368. The patent covers a cellular system. The precise claim scope was not adjudicated in this case, as the action was dismissed before any substantive proceedings took place.
Rule 41(a)(1)(A)(i) allows a plaintiff to dismiss an action as of right before the defendant has served an answer or a motion for summary judgment, with no court order required. The notice in this case states the dismissal is without prejudice. The specific terms of any arrangement between the parties are not disclosed in the available public record.
No. The case was dismissed before Movandi answered or any substantive briefing occurred. No finding of non-infringement, invalidity, or any other merits determination was entered. Movandi exits with no admission of liability and no judicial ruling on the patent's scope or validity.
