SharkNinja v. Schedule A Defendants: Ninja SLUSHi Design Patent Action Closed in 4 Days
SharkNinja Operating LLC filed suit in the Southern District of Florida asserting design patent USD1091236S covering the Ninja SLUSHi 88 oz. Professional Frozen Drink Maker against anonymous online marketplace sellers. The court closed the case sua sponte just four days after filing, requiring SharkNinja to refile motions in compliance with detailed procedural requirements before the case can be restored to the active docket.
Sua Sponte Closure: SharkNinja’s Schedule A Action Hits Procedural Gate
On November 14, 2025, SharkNinja Operating LLC filed Case No. 1:25-cv-25323 in the U.S. District Court for the Southern District of Florida before Judge Rodolfo A. Ruiz II, asserting infringement of design patent USD1091236S — which covers the ornamental appearance of the Ninja SLUSHi 88 oz. Professional Frozen Drink Maker. The defendants were identified only as individuals and entities listed on a Schedule A, a common structure in online marketplace anti-counterfeiting actions targeting sellers on platforms such as Amazon.
On November 18, 2025 — just four days after filing — the court issued a sua sponte order closing the case for administrative purposes only, without prejudice. Judge Ruiz denied all pending motions as moot and required SharkNinja to refile motions in full compliance with the order within 14 days. The closure is not a dismissal on the merits; the case can be restored to the active docket once defendants are properly served and all procedural requirements are met.
The four-day timeline reflects the Southern District of Florida’s increasingly rigorous gatekeeping of Schedule A IP actions rather than any substantive weakness in SharkNinja’s claims. The court’s order signals judicial scrutiny of personal jurisdiction over each defendant, alternate service procedures under Rule 4(f)(3), and Hague Convention compliance — requirements that have become standard hurdles in anonymous-defendant IP enforcement in this district. The public record does not yet reveal the identities of any defendants or whether TRO relief will ultimately be granted.
Filing to Case Terminated in 4 days
4 days — unusually swift administrative closure before any merits review
Administrative closure without prejudice: what the order means for both parties
Administrative closure ≠ dismissal on the merits
The court’s sua sponte order closed the case for ‘administrative purposes only, without prejudice.’ This is a procedural housekeeping measure, not a ruling on the validity of SharkNinja’s design patent or the merits of the infringement claim. SharkNinja retains the right to refile compliant motions within 14 days and to move to restore the case to the active docket once defendants are properly served.
Without prejudice — case survivesSharkNinja must clear procedural hurdles before injunctive relief
SharkNinja’s path to a temporary restraining order or preliminary injunction requires it to separately plead personal jurisdiction over each individual defendant, demonstrate the four-factor TRO standard as to each defendant, and satisfy alternate service requirements including Hague Convention analysis. The closure imposes real compliance costs but does not extinguish the underlying IP rights or the enforcement action.
Refiling required within 14 daysAnonymous sellers gain temporary respite — no injunction yet
Because the court denied all pending motions as moot, no temporary restraining order or asset freeze has been entered. Schedule A defendants — who have not yet been formally served or identified — benefit from the delay. However, the closure is explicitly without prejudice, meaning SharkNinja can and likely will refile. Defendants remain exposed to the full range of remedies once the procedural requirements are satisfied.
No TRO entered — exposure remainsS.D. Fla. tightening scrutiny of Schedule A marketplace actions
This order is consistent with a broader pattern in the Southern District of Florida, where judges have increasingly imposed sua sponte procedural requirements on mass-defendant Schedule A IP cases. For brand owners pursuing online marketplace enforcement, the order signals that boilerplate TRO filings face heightened judicial scrutiny — requiring granular per-defendant jurisdictional and service analysis before emergency relief will be considered.

Official order — verbatim text
The court’s sua sponte order is procedural rather than substantive — it makes no finding on infringement, patent validity, or damages. The order’s closure ‘for administrative purposes only, without prejudice’ means SharkNinja’s claims remain fully alive. The directive to refile separately structured motions, with per-defendant jurisdictional and service analysis, reflects Judge Ruiz’s established practice in Schedule A cases and signals that compliant refiling will be evaluated on its merits.
USD1091236S — Ninja SLUSHi 88 oz. Frozen Drink Maker ornamental design
USD1091236S is a U.S. design patent protecting the ornamental appearance of the Ninja SLUSHi 88 oz. Professional Frozen Drink Maker — a consumer appliance for producing frozen blended beverages. Design patents under 35 U.S.C. § 171 protect the distinctive visual characteristics of a product, not its functional features. The asserted patent covers the specific aesthetic design elements that distinguish the Ninja SLUSHi in the marketplace, making visual copying by third-party sellers an actionable infringement.
For SharkNinja, design patent protection on a hero consumer appliance like the SLUSHi serves a dual commercial function: it deters counterfeit physical products and look-alike listings on online marketplaces that erode brand equity and consumer trust. In the competitive frozen beverage appliance category — where shelf presence and distinctive form factor drive purchase decisions — a registered design patent provides a rapid enforcement pathway against sellers offering visually similar products without authorisation, including via Schedule A multi-defendant actions.
Should you run an FTO against USD1091236S for frozen drink maker designs?
Any manufacturer, importer, or online marketplace seller offering a frozen beverage appliance or frozen drink maker that resembles the Ninja SLUSHi’s ornamental design should assess freedom-to-operate against USD1091236S. This is particularly relevant for private-label brands, OEM suppliers in Asia, and marketplace resellers who source products with similar aesthetic profiles. A design patent infringement analysis applies the ‘ordinary observer’ test — if the overall appearance is substantially similar, liability may arise regardless of brand name.
PatSnap Eureka’s FTO Search Agent can map the design patent landscape around frozen beverage appliances, identify the visual claim scope of USD1091236S, surface related design and utility filings in SharkNinja’s portfolio, and flag commercially similar products already in litigation. Running an FTO before launching a competing product or marketplace listing reduces the risk of becoming a Schedule A defendant in a future SharkNinja enforcement action.

Portfolio viewWhat this case signals for the consumer appliance IP enforcement landscape
SharkNinja’s rapid administrative closure illustrates how procedural gatekeeping is reshaping online marketplace IP enforcement strategies.
Schedule A enforcement demands per-defendant jurisdictional diligence upfront
The S.D. Fla. order makes clear that blanket assertions of jurisdiction over anonymous marketplace sellers will no longer suffice. Brand owners must demonstrate individual personal jurisdiction for each Schedule A defendant — a requirement that significantly increases pre-filing investigation costs but also strengthens the evidentiary foundation for emergency relief.
Design patent enforcement against online counterfeits remains viable — but slower
The administrative closure does not signal that design patent claims like USD1091236S are weak. Rather, the court’s procedural demands suggest that well-prepared Schedule A complaints with robust per-defendant analysis will ultimately proceed. Brands that invest in pre-filing investigation are better positioned to survive sua sponte review and obtain TRO relief faster.
Hague Convention compliance is now a threshold issue in S.D. Fla. TRO motions
Judge Ruiz’s order specifically requires analysis of whether proposed alternate service is permitted by the Hague Convention for each defendant’s domicile. This suggests that foreign-based marketplace sellers — particularly those in non-Hague signatory countries or countries with restrictive service regimes — may require separate service strategies, adding complexity and cost to Schedule A campaigns.
Prior litigation search requirement creates settlement history disclosure risk
The court’s requirement that counsel disclose any prior suits, their outcomes, and settlement terms — including compliance with prior settlements — is an unusual transparency obligation. For serial Schedule A plaintiffs, this creates a disclosure record that defendants’ counsel could use to identify patterns, challenge good faith, or argue claim preclusion in future proceedings.
Sharkninja v INDIVIDUALS — key questions answered
The court closed the case for administrative purposes only, without prejudice to SharkNinja’s right to refile. This is not a dismissal on the merits. SharkNinja’s design patent claims remain valid and the company may restore the case to the active docket once defendants are properly served and all procedural requirements from the court’s order are satisfied.
USD1091236S is a U.S. design patent protecting the ornamental appearance of the Ninja SLUSHi 88 oz. Professional Frozen Drink Maker. Design patents cover the visual aesthetic of a product rather than its functional features, and infringement is assessed under the ‘ordinary observer’ standard — whether an ordinary consumer would find the accused design substantially similar to the patented design.
Judge Ruiz issued a sua sponte order reflecting the court’s established practice in Schedule A cases involving anonymous online marketplace defendants. The order required SharkNinja to separately refile its TRO motion, alternate service motion, and complaint with per-defendant jurisdictional allegations, Hague Convention analysis, and prior litigation disclosures — procedural standards the court has applied consistently in similar cases since at least 2024.
Yes. The closure is administrative only and explicitly preserves SharkNinja’s right to refile. Once SharkNinja files a compliant TRO motion — demonstrating likelihood of success on the merits, irreparable harm, balance of hardships, and public interest as to each defendant — the court can consider emergency relief. The 14-day compliance window suggests SharkNinja could seek TRO relief in early December 2025.
The court requires SharkNinja to identify the proposed service method for each defendant, establish each defendant’s domicile, explain what efforts were made to discover each domicile, and confirm whether the proposed alternate service method is permitted by the Hague Convention on the Service Abroad of Judicial and Extrajudicial Documents given that domicile. This is particularly demanding for defendants based in countries with restrictive service treaties.
