N99 LLC v. Sonifi Solutions: Hospitality Tech Patent Suit Dismissed Without Prejudice
N99 LLC filed suit in the Delaware District Court asserting two US patents — US11265364B2 and US11665224B2 — against Sonifi’s SORA, STAYCAST, stayconnect, and Health product lines. After 252 days and before Sonifi filed an answer, N99 voluntarily dismissed the action without prejudice, leaving the door open for future enforcement.
Early voluntary exit in a two-patent hospitality connectivity dispute
On October 6, 2023, plaintiff N99 LLC filed a patent infringement action in the District of Delaware against Sonifi Solutions, Inc., a provider of in-room hospitality technology. N99 asserted two issued US patents — US11265364B2 and US11665224B2 — against Sonifi’s Health products, SORA platform, STAYCAST casting solution, and stayconnect offering. The case was assigned to Judge Jon P. McCalla.
On June 7, 2024 — 252 days after filing — N99 filed a Notice of Dismissal under Fed. R. Civ. P. 41(a)(1)(A)(i), dismissing the action without prejudice. The court confirmed that Sonifi had not filed an answer or a motion for summary judgment; a pending Rule 12(b)(6) motion to dismiss did not bar the voluntary dismissal. The court formally closed the case and denied Sonifi’s motion to dismiss as moot.
The timeline suggests N99 chose to exit before the litigation entered its most costly phase. Because the dismissal is without prejudice, N99 retains the right to refile on the same patents against Sonifi or others. The public record is silent on whether any commercial resolution, licensing negotiation, or strategic reconsideration prompted the withdrawal, leaving the underlying IP dispute formally unresolved.

252 days — resolved before answer or summary judgment motion was filed
Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): dismissal as of right before answer
Under Fed. R. Civ. P. 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order simply by filing a notice — provided the defendant has not yet served an answer or a motion for summary judgment. Sonifi had filed only a Rule 12(b)(6) motion, which does not trigger that bar unless the court converts it. The court confirmed conversion had not occurred, making N99’s exit automatic and procedurally uncontested.
No court order requiredWithout prejudice — but the record is silent on why
A Rule 41(a)(1)(B) dismissal is without prejudice unless the notice states otherwise. N99’s notice did not specify prejudice terms. This distinction matters: without prejudice means N99 may refile the same claims against Sonifi or assert the same patents elsewhere. The public record does not reveal whether a licensing agreement, commercial settlement, or purely strategic recalibration drove the withdrawal. The door to future enforcement remains open.
Refiling remains possibleSonifi avoids merits ruling — but infringement cloud persists
Sonifi obtains a clean exit from this particular proceeding without any finding of infringement, validity, or damages. Its Rule 12(b)(6) motion was denied as moot rather than decided on the merits, so Sonifi gains no preclusive finding it can rely on in future proceedings. The patents-in-suit remain live and enforceable, meaning Sonifi’s SORA, STAYCAST, stayconnect, and Health products continue to carry infringement risk unless a license or design-around is secured.
No preclusive merit findingLive patents in a consolidating hospitality tech market
Both asserted patents — US11265364B2 and US11665224B2 — remain in force after this dismissal. Hospitality connectivity platforms competing with Sonifi’s product stack face the same patent risk N99 raised here. The without-prejudice exit signals that N99 may be positioning for licensing discussions or preparing a stronger infringement record before refiling. Competitors deploying in-room casting, streaming, or connectivity solutions should treat these patents as active enforcement vectors.

Official order — verbatim text
The court’s order confirms N99’s dismissal was self-executing under Rule 41(a)(1)(A)(i) — no judicial discretion was exercised on the merits. The finding that Sonifi’s Rule 12(b)(6) motion did not constitute an ‘answer or motion for summary judgment’ is consistent with Third Circuit authority. Critically, neither patent’s validity nor Sonifi’s alleged infringement was adjudicated, meaning the order carries no preclusive weight for either party in future proceedings involving US11265364B2 or US11665224B2.
US11265364B2 & US11665224B2 — Hospitality Connectivity & Content Delivery
US11265364B2 (App. No. 17/007107) and US11665224B2 (App. No. 17/569401) are both issued US patents asserted against Sonifi’s suite of in-room hospitality technology products. The patents sit within the hospitality connectivity domain — a sector that has seen rapid technology evolution as hotels shift from legacy coaxial systems to cloud-managed, guest-device-integrated platforms. Both patents issued post-2021, suggesting relatively recent claim vintages that may track current product architectures closely.
For competitors deploying in-room casting, streaming, or network management platforms in the hospitality vertical, both patents represent active enforcement risk. N99’s willingness to assert them against Sonifi’s flagship products — SORA, STAYCAST, stayconnect, and Health — signals that the claim scope is broad enough to read on commercially significant hospitality connectivity solutions. The without-prejudice dismissal leaves both patents in a posture where enforcement activity could resume against Sonifi or be directed at other market participants.
Should you run an FTO against US11265364B2 and US11665224B2?
Any company developing or commercialising in-room hotel connectivity, casting, guest device management, or cloud-managed content delivery should treat these two patents as priority FTO targets. N99’s assertion against Sonifi’s full product stack — covering SORA, STAYCAST, stayconnect, and Health — indicates the patentee reads the claims broadly across hospitality platform architectures. The without-prejudice dismissal means no invalidity finding limits enforcement risk.
PatSnap Eureka’s FTO Search Agent allows R&D and product teams to map their specific hospitality platform features against the claim language of US11265364B2 and US11665224B2, identify prosecution history estoppel, and surface prior art that could support an IPR petition or design-around strategy. Early-stage FTO analysis is significantly lower cost than defending a second filing after N99’s litigation posture has strengthened.

What this case signals for the hospitality technology IP landscape
An early voluntary exit on two live connectivity patents suggests ongoing enforcement risk across the hotel tech sector.
Without-prejudice dismissals preserve maximum leverage for patent holders
N99’s exit before Sonifi filed an answer is textbook Rule 41 strategy: no merits exposure, no adverse finding, and full freedom to refile. Companies in the hospitality tech space should monitor N99’s portfolio for refiling activity, particularly if Sonifi or peers launch updated versions of SORA, STAYCAST, or stayconnect.
Sonifi’s 12(b)(6) motion yielded no preclusive protection
Defendants who rely solely on a motion to dismiss risk seeing it mooted by a voluntary dismissal. Sonifi’s inability to convert the motion into a merits ruling means it holds no invalidity or non-infringement finding it can deploy against a refile. In-house teams facing similar early-stage suits should assess whether seeking a declaratory judgment or accelerating to summary judgment better protects long-term product freedom.
N99 v Sonifi — key questions answered
N99 LLC filed a patent infringement suit against Sonifi Solutions in the Delaware District Court on October 6, 2023, asserting US11265364B2 and US11665224B2 against Sonifi’s SORA, STAYCAST, stayconnect, and Health products. On June 7, 2024, N99 voluntarily dismissed the action without prejudice under Fed. R. Civ. P. 41(a)(1)(A)(i). The court closed the case on June 14, 2024, and denied Sonifi’s pending Rule 12(b)(6) motion as moot.
A dismissal without prejudice means N99 retains the right to refile the same infringement claims against Sonifi or assert the same patents against other defendants. Neither patent’s validity was adjudicated, and no finding of non-infringement was made. Both patents remain in force and enforceable. The dismissal carries no preclusive effect for either party in future proceedings.
Under Fed. R. Civ. P. 41(a)(1)(A)(i), a plaintiff’s right to voluntary dismissal is only extinguished once the defendant has served an answer or a motion for summary judgment. A Rule 12(b)(6) motion to dismiss does not constitute either. Per Third Circuit authority in In re Bath & Kitchen Fixtures Antitrust Litig., the motion only triggers the bar if the court converts it to a summary judgment motion by accepting outside materials — which the court had not done here.
N99’s complaint identified four Sonifi product lines as accused products: Sonifi’s Health products, the SORA platform, the STAYCAST casting solution, and stayconnect. These products collectively represent Sonifi’s in-room hospitality technology stack, covering health-related in-room services, streaming, content casting, and guest connectivity.
No. Because the case was dismissed before any merits ruling, neither the validity nor the enforceability of US11265364B2 or US11665224B2 was adjudicated. Sonifi’s Rule 12(b)(6) motion was denied as moot, not on the merits. Companies seeking to challenge these patents would need to pursue IPR proceedings at the USPTO or raise invalidity defenses in any future litigation brought by N99.
