Err Content IP v. FuboTV: Voluntary Dismissal Without Prejudice in 23 Days
Err Content IP, LLC asserted US10721542B2 against FuboTV's streaming app and casting system in the Southern District of New York. Before FuboTV answered or moved, the plaintiff filed a Rule 41(a)(1)(A)(i) notice of voluntary dismissal without prejudice — closing the case in just 23 days.
Streaming patent case dropped before FuboTV filed any response
On 18 March 2026, Err Content IP, LLC filed an infringement action against FuboTV, Inc. in the U.S. District Court for the Southern District of New York, assigned to Judge Jennifer H. Rearden. The sole patent asserted was US10721542B2, directed at technology implicated by the FuboTV app system and its Chromecast casting functionality.
The case closed on 10 April 2026 — just 23 days after filing. The recorded basis of termination is Voluntary Dismissal. The docket order is a plaintiff-filed notice under Federal Rule of Civil Procedure 41(a)(1)(A)(i), stating that the dismissal is without prejudice and noting that FuboTV had not yet answered the complaint or filed a motion for summary judgment at the time of dismissal.
A dismissal at this stage — before any defendant response — is procedurally significant: under Rule 41(a)(1)(A)(i), a plaintiff may dismiss as of right, without court approval, precisely because no answer or dispositive motion has been filed. Whether the early exit reflects a settlement, a licensing discussion, a strategic reassessment, or another factor is not disclosed in the available public record.

US10721542B2 — streaming media app and device casting system
Any streaming platform, connected TV app developer, or live TV delivery service that enables users to cast content from a mobile or web app to a television — particularly via Chromecast or similar protocols — should assess their exposure to US10721542B2. The without-prejudice dismissal in this case means the patent remains fully enforceable and the claims have not been adjudicated.
Official order — verbatim text
The plaintiff's Rule 41(a)(1)(A)(i) notice confirms the dismissal is without prejudice and records that FuboTV had not answered or moved at the time of filing. No merits determination — on infringement, validity, or claim scope — was reached. The notice closes this particular docket but does not extinguish the underlying patent rights or Err Content IP's ability to pursue future enforcement.
Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i) dismissal: plaintiff's unilateral right to exit
Under FRCP Rule 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice of voluntary dismissal before the defendant serves an answer or a motion for summary judgment. That threshold had not been crossed here, so Err Content IP could exit as of right. No judicial approval was required.
Procedural — no merits rulingDismissal without prejudice leaves the door open to refile
A dismissal without prejudice does not adjudicate the underlying infringement claims on their merits. Err Content IP expressly agreed in the notice that the dismissal is without prejudice. This means the plaintiff retains the right to refile claims based on US10721542B2 — subject to applicable statutes of limitations and any other procedural bars. The specific terms, if any, that accompanied this exit are not disclosed in the available public record.
Plaintiff may refileFuboTV exits without an adverse judgment — but exposure persists
FuboTV, Inc. never filed an answer, making this the earliest possible exit point. The company faces no injunction, no damages award, and no adverse finding on validity or infringement. However, because the dismissal is without prejudice, FuboTV's Chromecast casting system and app infrastructure remain potentially exposed to a future refiled action asserting the same patent.
No adverse ruling — latent risk remainsStreaming app casting tech remains under patent assertion pressure
The assertion of US10721542B2 against FuboTV's Chromecast-based casting system signals continued patent assertion activity in the streaming media and app-based TV delivery sector. Competitors and partners operating similar app-to-TV casting architectures should note that a without-prejudice exit does not signal patent invalidity or non-infringement — those questions remain unresolved on the merits.

Err Content IP's patent holdings and assertion activity
Err Content IP, LLC is the recorded assignee of US10721542B2. Streaming platform operators and their IP counsel should monitor whether this entity holds additional patents in the streaming media or app-based device casting space, and whether further assertion actions are filed in this or other jurisdictions following the without-prejudice exit.
PAE portfolio monitoringPatent filing trends in app-to-TV casting and streaming delivery
App-based casting to connected TV devices — including Chromecast, AirPlay, and DLNA protocols — is an active area of patent filing by both established streaming platforms and patent assertion entities. Understanding the density and claim scope of competing filings around US10721542B2 helps operators identify freedom-to-operate gaps and design-around opportunities.

FuboTV, Inc. operates a sports-focused live TV streaming platform with app-based delivery across multiple device types. Assessing FuboTV's own patent filings in streaming architecture, content delivery, and casting-related technology provides context for how the company may respond to future patent assertions in this domain.

What this case signals for the streaming media IP landscape
A 23-day lifecycle and a without-prejudice exit raise more questions than answers for streaming platform operators and their IP counsel.
Early dismissal without prejudice is not a clean bill of health for FuboTV
A Rule 41(a)(1)(A)(i) dismissal before any defendant response carries no merits determination. FuboTV's casting and streaming app infrastructure has not been adjudicated as non-infringing. IP counsel monitoring this space should treat the patent as still active and the claims as unresolved.
Streaming platforms with Chromecast-style casting should audit US10721542B2 claims
The asserted product scope — FuboTV's app system and Chromecast casting functionality — covers architecture common across live TV streaming services. Any platform using comparable app-to-TV casting protocols should review claim scope against their implementation, particularly given the without-prejudice nature of this dismissal.
Err v FuboTV — key questions answered
Err Content IP, LLC filed a patent infringement action against FuboTV, Inc. in the Southern District of New York on 18 March 2026, asserting US10721542B2 against FuboTV's app and Chromecast casting system. The case was voluntarily dismissed without prejudice on 10 April 2026 — 23 days after filing — before FuboTV filed any answer or motion.
A dismissal without prejudice does not resolve the infringement claims on the merits. FuboTV faces no adverse judgment, injunction, or damages award from this case. However, Err Content IP retains the right to refile claims under US10721542B2 against FuboTV or other defendants, subject to applicable statutes of limitations. The specific terms of the exit are not disclosed in the available record.
The sole patent asserted was US10721542B2 (application number US14/396843). The accused product is identified as the FuboTV app system and related systems, specifically including the platform's Chromecast casting functionality. The specific claims asserted and their technical scope are not detailed beyond this product identification in the available public record.
Under FRCP Rule 41(a)(1)(A)(i), a plaintiff may file a notice of voluntary dismissal as of right — without court approval — provided the defendant has not yet served an answer or a motion for summary judgment. FuboTV had not taken either step at the time of dismissal, so Err Content IP was entitled to dismiss unilaterally by notice alone.
No IPR petition, post-grant review, or adversarial validity challenge is recorded in the available case record for US10721542B2. No claim construction or invalidity ruling was issued in this case. The patent's claims remain untested in adversarial proceedings based on the available public record.
