Aperçu du dossier
A patent infringement dispute over USB charging technology ended swiftly when VoltStar Technologies, Inc. and Roku, Inc. reached an in-principle settlement, prompting the Southern District of New York to dismiss the case without prejudice on March 13, 2024 — just 131 days after filing. The case, docketed as 1:23-cv-09709, centered on two patents covering power charging technology and specifically accused Roku’s Micro USB Charger of infringement.
While no judgment on the merits was issued, the case’s rapid resolution carries meaningful signals for patent holders asserting charging technology patents, consumer electronics companies managing IP exposure, and R&D teams navigating freedom-to-operate risks in the competitive USB and power delivery space.
For patent attorneys and IP professionals tracking USB charging patent infringement litigation, this matter illustrates both the persistence of patent assertion in consumer electronics accessories and the continued prevalence of pre-trial settlement as a strategic endgame in district court infringement actions.
Les parties
⚖️ Demandeur
A patent-holding entity asserting intellectual property rights in power charging technology.
🛡️ Défendeur
A publicly traded streaming media company recognized for its streaming devices, smart TV platforms, and consumer accessories.
Les brevets en cause
This litigation centered on two patents covering power charging technology:
- • U.S. Patent No. 9,024,581 B2 — Directed to charging circuit technology in the USB power delivery space, covering innovations in voltage regulation and charging efficiency.
- • U.S. Reissue Patent No. RE48,794 E — A reissue of an earlier patent, broadening or correcting claims related to the same charging technology domain.
Le produit incriminé
The sole accused product was the **Roku Micro USB Charger** — a power accessory sold in connection with Roku’s streaming hardware ecosystem. The commercial significance is notable: USB charger accessories represent recurring consumer revenue and broad market distribution, making them attractive targets for patent assertion.
Représentation juridique
Plaintiff VoltStar was represented by Joseph Anthony Dunne of Sriplaw PLLC, while Defendant Roku was represented by Rebekah Raye Conroy of Walder Hayden, PA.

Le verdict et l'analyse juridique
Chronologie du litige et historique de la procédure
VoltStar filed suit in the U.S. District Court for the Southern District of New York. The case was assigned to Chief Judge P. Kevin Castel. The 131-day lifecycle from filing to dismissal indicates that the parties reached settlement well before any substantive motions practice, claim construction proceedings, or trial preparation phases were completed. No Markman hearing, summary judgment ruling, or damages determination appears in the record.
| Plainte déposée | 3 novembre 2023 |
| Affaire classée | March 13, 2024 |
| Durée totale | 131 days |
Résultat
The Southern District of New York dismissed the action without prejudice following notice to Judge Castel that all asserted claims had been settled in principle. No damages were awarded, no injunctive relief was issued, and no findings of infringement or validity were made on the merits. The specific financial terms of the settlement were not disclosed in the public record.
Critically, Judge Castel’s order clarified that the court would not retain jurisdiction to enforce any settlement agreement unless the agreement was submitted and “so ordered” by the court within the 30-day window — a procedural nuance with practical enforceability implications for the parties.
Signification juridique
Although this case produced no precedential ruling, several elements carry analytical weight:
- Reissue Patent Assertion: The use of RE48,794 E alongside US9,024,581 B2 reflects a portfolio layering strategy — coupling an original patent with a reissued counterpart to maximize claim coverage against an accused product.
- Venue Selection: S.D.N.Y. filing against a nationally distributed consumer product demonstrates continued plaintiff flexibility in venue selection post-*TC Heartland*, where a defendant’s principal place of business or regular business activities may support venue.
- Settlement Without Prejudice: Dismissal without prejudice preserves VoltStar’s ability to re-assert these patents in future litigation, including against other defendants in the USB charger market.
