Edelta v. Great Innovations: iFLO A/C Drain Patent Case Dismissed Without Prejudice
Edelta, Inc. and inventor John S. Gutierrez sued Great Innovations, LLC over US9943778B1, a patent covering the iFLO Smart Automated A/C Drain Line & Drain Pan Cleaning System. Filed in the Florida Southern District Court, the infringement action lasted just 19 days before plaintiffs voluntarily dismissed without prejudice, leaving the door open for re-filing.
A swift voluntary exit: Edelta’s 19-day A/C drain patent action
On 25 August 2024, Edelta, Inc. and individual plaintiff John S. Gutierrez filed a patent infringement action in the U.S. District Court for the Southern District of Florida (Case No. 0:24-cv-61564) against Great Innovations, LLC and Joseph McDonnell. The asserted patent, US9943778B1, covers the iFLO Smart Automated A/C Drain Line & Drain Pan Cleaning System — a product in the HVAC maintenance technology space. The case was assigned to Judge Raag Singhal and represented on the plaintiff side by attorney Louis R. Gigliotti.
Just 19 days after filing, on 13 September 2024, the plaintiffs filed a Notice of Voluntary Dismissal without Prejudice (DE [8]). Judge Singhal reviewed the notice and entered an order dismissing the matter without prejudice, directing the Clerk to close the case and denying all pending motions as moot. A dismissal without prejudice means no final judgment was entered on the merits, and the plaintiffs retain the legal right to re-file the same infringement claims against the same defendants in the future.
The 19-day lifespan of this action — ending before any defendant appearance or substantive briefing on the record — suggests the dismissal was likely driven by a pre-litigation settlement, licensing negotiation, or a strategic reassessment of the case. The public record is silent on the specific motivation. Because the dismissal is without prejudice, any resolution between the parties cannot be confirmed from court documents alone, and the underlying patent remains enforceable.

Voluntarily dismissed without prejudice: what the order means for both parties
Voluntary dismissal without prejudice under Rule 41
A voluntary dismissal without prejudice, governed by Federal Rule of Civil Procedure 41(a), is a plaintiff-initiated exit before the defendant has served an answer or summary judgment motion. It carries no merit-based adjudication — the court makes no finding on infringement, validity, or damages. Critically, it is ‘without prejudice’, meaning the same claims can be re-filed in the future, subject to the statute of limitations.
No merits ruling enteredWithout prejudice vs. with prejudice — the public record is silent on why
A dismissal with prejudice would permanently bar the plaintiff from re-filing on the same patent claims. A dismissal without prejudice preserves that right. This order is explicitly without prejudice. However, the public record does not disclose whether an out-of-court agreement — such as a license or settlement — was reached. Practitioners should not assume a resolution was achieved; the case may simply have been withdrawn for strategic or procedural reasons.
Re-filing right preservedEdelta retains enforcement rights — case can be re-filed
Because no prejudice attaches, Edelta and Gutierrez are not barred from reasserting US9943778B1 against Great Innovations or other parties. If the dismissal reflects an unresolved dispute rather than a settlement, defendants remain exposed to future litigation. Patent holders in HVAC technology segments have increasingly used sequential filings as a monitoring and enforcement tactic.
Future enforcement possibleGreat Innovations avoids judgment — but uncertainty persists
Great Innovations and McDonnell achieved dismissal without any court finding against them, and incurred no cost order. However, a without-prejudice dismissal provides no immunity. If no license was granted, the defendants face continued exposure under US9943778B1. Companies in the A/C drain maintenance and HVAC accessories space should monitor the patent’s status and any re-filing activity by Edelta.

Official order — verbatim text
The court’s order tracks the plaintiff’s Notice of Voluntary Dismissal directly, entering dismissal without prejudice and mooting all pending motions. The phrasing ‘DISMISSED WITHOUT PREJUDICE’ confirms no merits determination was made — neither infringement nor invalidity was adjudicated. For practitioners, this means US9943778B1 exits the litigation record unscathed, and Great Innovations carries no res judicata protection against future assertions of the same patent.
US9943778B1 — iFLO Smart Automated A/C Drain Line & Drain Pan Cleaning System
US9943778B1 (application number US14/560469) covers the iFLO Smart Automated A/C Drain Line & Drain Pan Cleaning System — a technology in the HVAC preventive maintenance space designed to automate the clearing of condensate drain lines and pans in air conditioning units. Such systems address a common failure point in residential and commercial HVAC installations where blockages cause water damage and system inefficiency. The patent’s B1 designation indicates it issued without post-issuance amendment, suggesting its claims emerged from prosecution in their original form.
In the HVAC accessories and smart home maintenance market, automated drain cleaning systems represent a niche but commercially relevant segment. A granted patent in this space can create meaningful barriers for competitors offering similar automated or IoT-connected drain maintenance products. The assertion of this patent against Great Innovations — a company whose name suggests a product innovation focus — is consistent with enforcement against a direct competitive offering. Companies developing connected HVAC maintenance devices should assess claim scope carefully before product launch.
Should you run an FTO analysis against US9943778B1?
Any company designing, manufacturing, importing, or selling automated A/C drain line cleaning systems, drain pan maintenance devices, or connected HVAC preventive maintenance products in the U.S. market should consider a freedom-to-operate review against US9943778B1. The patent has been actively asserted, and the without-prejudice dismissal confirms it remains enforceable. The risk is particularly relevant for products targeting residential or commercial HVAC installation aftermarkets.

What this case signals for the HVAC accessories IP landscape
A 19-day patent action in the A/C drain cleaning space raises questions about enforcement strategy, licensing intent, and sector-wide patent risk.
Short-duration dismissals often precede licensing deals or re-filings
When plaintiffs voluntarily dismiss within weeks of filing — before any defendant answer — it typically signals either a rapid out-of-court resolution or a strategic pause. Neither outcome is confirmed here. Companies in the HVAC maintenance product space should track Edelta’s subsequent filings to assess whether a broader enforcement campaign is underway.
US9943778B1 remains active and enforceable post-dismissal
The without-prejudice dismissal has no effect on the validity or enforceability of US9943778B1. Any competitor manufacturing, selling, or distributing automated A/C drain line or drain pan cleaning systems should conduct a freedom-to-operate review against this patent before market entry or product launch.
