Watchy Technology v. Dejero: Bandwidth Patent Suit Dismissed With Prejudice
Watchy Technology Private Limited filed suit against Dejero, Inc. and Dejero Labs, Inc. in Delaware’s District Court, asserting US10454726B2 — a patent covering systems for increasing available data communication bandwidth. The action lasted 553 days before Watchy voluntarily dismissed with prejudice, ending enforcement of this patent against Dejero permanently.
A 553-Day Bandwidth Patent Campaign Ends at Plaintiff’s Own Hand
On April 26, 2023, Watchy Technology Private Limited, an India-incorporated technology company, filed a patent infringement complaint in the District of Delaware against two related entities — Dejero, Inc. and Dejero Labs, Inc. The asserted patent, US10454726B2, protects a system for increasing the bandwidth available for data communication, a technology domain directly relevant to Dejero’s live video transport and connectivity solutions. The case was assigned to Judge J. Nicholas Ranjan.
On October 30, 2024 — 553 days after filing — Watchy invoked Federal Rule of Civil Procedure 41(a)(1)(A)(i) to voluntarily dismiss the action with prejudice. Critically, the notice confirms that neither Dejero, Inc. nor Dejero Labs, Inc. had served an answer or a motion for summary judgment at the time of dismissal. A with-prejudice dismissal under this rule is final: Watchy cannot re-file the same infringement claims against these defendants in any federal court.
The extended pre-answer phase — over 18 months without a responsive pleading — is commercially unusual and suggests the parties may have engaged in settlement or licensing discussions during this window, though the public record is silent on any agreement. The with-prejudice designation forecloses future litigation on these claims against Dejero, making the resolution effectively final for both parties regardless of whether consideration changed hands.

Voluntarily dismissed with prejudice: what this means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral right to exit
Federal Rule 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order at any time before the defendant serves an answer or a motion for summary judgment. Watchy exercised this right, adding a with-prejudice designation. That election transforms a procedural tool into a final adjudication on the merits — the claims are extinguished as if fully litigated and decided against the plaintiff.
Plaintiff-initiated exitPermanent bar: these claims cannot be re-filed against Dejero
A voluntary dismissal with prejudice operates as a final judgment on the merits under res judicata principles. Watchy is permanently barred from asserting the same US10454726B2 infringement claims against Dejero, Inc. and Dejero Labs, Inc. in any federal forum. Had the dismissal been without prejudice, Watchy could have refiled. The public record does not disclose why Watchy chose the more restrictive with-prejudice designation — this distinction is material and its rationale is not apparent from the docket alone.
Claims permanently extinguishedDejero secures permanent freedom from this infringement claim
Dejero, Inc. and Dejero Labs, Inc. exited litigation without filing a single responsive pleading, incurring no merits litigation costs on the docket. The with-prejudice dismissal affords them lasting protection against re-assertion of US10454726B2 claims by Watchy. However, the patent itself remains in force and could theoretically be asserted against other parties or assigned to a new owner who might pursue separate enforcement actions.
No merits exposure for DejeroPatent survives — exposure shifts to the broader sector
US10454726B2 has not been invalidated, and Watchy retains ownership. Companies operating in the bandwidth aggregation and live video transport sector — particularly those with products competitive to Dejero’s — should note that the patent remains an active enforcement risk. The dismissal resolves only the Dejero dispute. Other players in wireless bonding, multi-path data transport, and broadcast connectivity could face assertion if Watchy pursues a broader licensing or enforcement strategy.

Official order — verbatim text
The dismissal notice explicitly confirms that Dejero had not served an answer or motion for summary judgment — making Watchy’s unilateral Rule 41(a)(1)(A)(i) right available without court approval. The with-prejudice election is the legally significant detail: it was Watchy’s choice alone, and it permanently extinguishes these specific claims against these defendants. The phrasing provides no indication of any agreed terms, payment, or licensing arrangement, though the circumstances are consistent with a negotiated resolution reached outside the formal docket.
US10454726B2 — System for Increasing Bandwidth Available for Data Communication
US10454726B2, filed under application number US15/744062, protects a system architecture for increasing the bandwidth available for data communications — a core technology in multi-path and bandwidth bonding applications. The patent is held by Watchy Technology Private Limited and covers methods and systems relevant to environments where a single network path is insufficient, requiring aggregation across multiple channels. This places it squarely in the live video transport, broadcast, and enterprise connectivity domains.
For the bandwidth aggregation and live video transport sector, US10454726B2 represents a meaningful enforcement asset. Dejero’s commercial products — which aggregate cellular and other network connections for broadcast-quality live video transmission — sit precisely in the technological space this patent addresses. The patent has not been challenged via IPR or subjected to any validity ruling in this case, meaning it carries full presumptive validity. Any competitor offering similar multi-path bandwidth systems should treat this patent as an active risk until its claims are formally narrowed or invalidated.
Should your team run an FTO against US10454726B2?
If your product aggregates multiple data channels to increase effective bandwidth — whether for live video transport, cellular bonding, broadcast contribution, or enterprise WAN failover — US10454726B2 is directly relevant to your freedom-to-operate position. The Dejero dismissal removes only those defendants from Watchy’s reach; the patent remains fully enforceable against all other parties. Product teams shipping multi-path connectivity hardware or software in markets where Watchy may assert should commission an FTO analysis before product launch or market expansion.

What this case signals for the bandwidth aggregation IP landscape
A with-prejudice exit after 18 months of silence raises questions about licensing, portfolio strategy, and risk for adjacent technology companies.
Pre-answer silence for 18 months is a structural anomaly worth noting
Most Delaware patent defendants answer within 21–60 days or seek extension. Dejero’s prolonged non-response — and Watchy’s tolerance of it — suggests the parties conducted out-of-court engagement. Companies monitoring similar suits should track docket inactivity as a potential signal of parallel licensing talks, not just procedural delay.
With-prejudice designation limits Watchy’s future Delaware enforcement against Dejero
By electing dismissal with prejudice, Watchy permanently closed this avenue of enforcement against Dejero. This is an unusually restrictive choice when no litigation cost pressure existed (no answer had been filed). It may reflect a concluded commercial arrangement, a strategic portfolio decision, or counsel-driven risk calculus — none of which are visible on the public record.
Limited v Dejero — key questions answered
A voluntary dismissal with prejudice under Rule 41(a)(1)(A)(i) permanently bars Watchy Technology from re-asserting the same US10454726B2 infringement claims against Dejero, Inc. and Dejero Labs, Inc. in any federal court. It operates as a final adjudication on the merits under res judicata, even though no court ever ruled on the substance of the infringement allegations.
The public record is silent on the reason. The dismissal notice confirms Dejero had not served an answer or summary judgment motion at the time, making Watchy’s unilateral exit available as of right. The 553-day duration before dismissal is consistent with parties conducting parallel licensing or settlement discussions, though no agreement is disclosed on the docket.
Yes. The dismissal resolves only the claims against Dejero, Inc. and Dejero Labs, Inc. US10454726B2 was never ruled invalid or unenforceable, and Watchy retains ownership. The patent carries full presumptive validity and can be asserted against other parties operating in the bandwidth aggregation and data communication space.
US10454726B2 (application no. US15/744062), held by Watchy Technology Private Limited, covers a system for increasing the bandwidth available for data communication. It is relevant to multi-path networking, bandwidth bonding, and data channel aggregation — technologies used in live video transport, broadcast contribution, and enterprise connectivity products.
Rule 41(a)(1)(A)(i) allows a plaintiff to dismiss as of right — without court approval — before the defendant serves an answer or summary judgment motion. This gives the plaintiff full control over the exit terms, including the choice of with- or without-prejudice designation. Choosing with-prejudice under these circumstances is significant: it is more restrictive than required and typically suggests the plaintiff has obtained something of value, reached a resolution, or made a strategic portfolio decision.
