Fka Distributing v. Blulabs Brands: Ultrasonic Diffuser Patent Dispute Settled in 147 Days
Fka Distributing Co., LLC filed suit against Blulabs Brands LLC in Florida’s Southern District, asserting two patents covering ultrasonic diffuser technology across ten named products including The Alpine and The Flute Ultrasonic Diffuser. The parties reached a settlement within 147 days — well below the median time-to-resolution for patent infringement actions at the district court level.
Ultrasonic Diffuser Patent Row Ends in Fast Settlement
On 12 February 2025, Fka Distributing Co., LLC filed an infringement action against Blulabs Brands LLC in the United States District Court for the Southern District of Florida, before Judge Beth Bloom. The complaint asserted two patents — US7303300B2 and US7652436B2 — against ten Blulabs products, including The Alpine, The Belle Wood-Look Ultrasonic Diffuser, The Constellation, The Flute Ultrasonic Diffuser, The Glass Temple, The Luxe Alpine, The Mehdi, The Orb, The Rudolf, and The Ultrasonic Mini Alpine Diffuser.
The case resolved on 9 July 2025 following a Notice of Settlement filed as ECF No. 20. Judge Bloom administratively closed the action without prejudice, cancelling all pending hearings and denying outstanding motions as moot, while preserving the parties’ ability to file formal dismissal documentation. The administrative closure without prejudice is a procedural step standard in settlements, not a merits determination — the substantive resolution is captured in the private settlement agreement.
The 147-day resolution is notably swift for a two-patent infringement action with ten accused products, suggesting that one or both parties assessed early settlement as commercially preferable to prolonged litigation — whether driven by licensing economics, product substitution, or litigation cost exposure. The precise financial terms, licensing scope, and any product modifications required remain confidential and are not apparent from the public docket.

Case settled: what the administrative closure means for both parties
Administrative closure without prejudice explained
When parties settle, courts often administratively close the case without prejudice pending formal dismissal paperwork. This is not a dismissal on the merits — it is a housekeeping step. The case remains re-openable if the settlement agreement is breached or if the parties fail to file agreed dismissal documents. Expect a formal stipulated dismissal to follow.
Procedural step, not merits rulingFka Distributing achieves resolution without full trial risk
As the patent holder, Fka Distributing secured a settlement across a ten-product accused range within five months of filing. Settlement typically allows the plaintiff to obtain compensation, licensing terms, or a cease-and-desist commitment without the uncertainty and expense of claim construction, summary judgment, and trial. The specific value exchanged is not public.
Private terms — public record silentBlulabs avoids prolonged litigation, terms undisclosed
Blulabs Brands LLC resolved the dispute before any substantive court ruling on infringement or validity. This may reflect a commercial licence, product design modification, or financial payment — or a combination. The absence of a court judgment means no public admission of infringement. Early settlement is consistent with a defendant seeking to preserve business continuity and avoid discovery costs.
No infringement finding on recordTwo asserted patents remain enforceable post-settlement
Neither US7303300B2 nor US7652436B2 was challenged through IPR or invalidated during this proceeding. Settlement without a validity determination leaves both patents fully enforceable against other market participants. Competitors offering ultrasonic diffuser products in overlapping product categories should treat both patents as live enforcement risks.

Official order — verbatim text
The court’s order reflects a standard administrative settlement closure: no merits adjudication occurred and no infringement or invalidity finding was made. The phrase ‘without prejudice’ preserves the parties’ ability to re-open proceedings if settlement terms are breached. The denial of pending motions as moot confirms that no substantive rulings — including any claim construction positions — entered the public record. The private settlement agreement governs the parties’ rights going forward.
US7303300B2 & US7652436B2 — Ultrasonic Diffuser Technology
US7303300B2 and US7652436B2 both sit within the ultrasonic diffuser technology domain — covering devices that use high-frequency vibration to atomise liquids, typically essential oils or water, into fine mist for consumer home environments. The application numbers (US10/656807 and US11/949497) suggest original filings in the early-to-mid 2000s, a period of rapid commercialisation in consumer aromatherapy and home fragrance hardware. These patents likely address device configuration, transducer arrangements, or operational and aesthetic features that differentiate ultrasonic diffusers from prior misting technologies.
For the consumer home fragrance and wellness sector, these patents represent meaningful IP infrastructure. The ten accused products — spanning wood-look, glass, orb, and mini form factors — suggest that the asserted claims are not narrowly confined to a single design, but may cover broader functional or structural elements applicable across a product family. Any brand developing, importing, or distributing ultrasonic diffuser hardware in the US should assess whether their product architecture falls within the claim language of either patent before entering or expanding in the market.
Should you run an FTO against US7303300B2 and US7652436B2?
Any company designing, manufacturing, or distributing ultrasonic diffuser products for the US consumer market should treat these two patents as primary FTO checkpoints. This case demonstrates active enforcement across a wide product range — from entry-level mini diffusers to premium wood-look and glass designs. If your product uses ultrasonic transducer technology to generate mist or aroma dispersal, a claim-level FTO analysis against both patents is warranted before US product launch or distribution scaling.

What this case signals for the ultrasonic diffuser IP landscape
A rapid settlement across ten accused products reinforces that ultrasonic diffuser IP is actively enforced and commercially potent in the US market.
Two patents, ten products: Fka Distributing signals broad enforcement intent
By naming ten SKUs across a single defendant, Fka Distributing demonstrates a willingness to assert comprehensive product-level coverage under its patents. Competitors offering similar ultrasonic diffuser product lines should assess exposure under US7303300B2 and US7652436B2 before scaling distribution in the US market.
Fast settlement timeline suggests strong patent position or acute commercial pressure
A 147-day resolution — before any Markman hearing or summary judgment — typically indicates one of two things: a defendant who found it commercially rational to settle quickly, or a plaintiff with sufficient claim strength to create early settlement pressure. Either signal is material for third parties mapping freedom-to-operate in this space.
Fka v Blulabs — key questions answered
Fka Distributing asserted two patents: US7303300B2 (application no. US10/656807) and US7652436B2 (application no. US11/949497). Both relate to ultrasonic diffuser technology. Ten specific Blulabs products were named as accused infringers, including The Alpine, The Flute Ultrasonic Diffuser, The Belle Wood-Look Ultrasonic Diffuser, and The Orb.
The case was resolved via settlement. Judge Beth Bloom issued an order administratively closing the case without prejudice after a Notice of Settlement was filed (ECF No. 20). This is a procedural closure — not a merits ruling. The parties retained the right to file formal dismissal documentation. The substantive settlement terms are private and not in the public record.
No. The case settled before any substantive ruling on validity or infringement. There is no indication in the public docket that either patent was challenged via IPR, ex parte reexamination, or any inter partes proceeding during the litigation. Both patents should be treated as presumptively valid and actively enforceable.
Ten products were named: The Alpine, The Belle Wood-Look Ultrasonic Diffuser, The Constellation, The Flute Ultrasonic Diffuser, The Glass Temple, The Luxe Alpine Ultrasonic Diffuser, The Mehdi, The Orb, The Rudolf, and The Ultrasonic Mini Alpine Diffuser. The breadth of named products suggests the asserted claims cover functional or structural elements common across multiple diffuser form factors.
The case resolved in 147 days from filing to administrative closure — notably fast for a two-patent, ten-product infringement action. The typical patent infringement case in a US district court takes 18–36 months to trial. A 147-day settlement suggests either strong plaintiff leverage, commercial urgency on the defendant’s side, or both. No Markman hearing or summary judgment motion was adjudicated before resolution.
