Kyjen Co. v. Schedule A Defendants: Injunction Granted in 53-Day Pet Products IP Battle
Kyjen Co., LLC — holder of 9 design patents and one utility patent covering pet products — filed suit in Florida’s Southern District Court against anonymous Schedule A defendants, predominantly e-commerce sellers. Within 53 days, Judge Roy K. Altman granted an ex parte TRO and preliminary injunction, freezing seller funds and ordering Amazon compliance within one calendar day.
Kyjen’s 10-Patent Schedule A Strike Secures Swift Injunction in S.D. Fla.
On April 14, 2025, Kyjen Co., LLC filed a patent infringement action before Judge Roy K. Altman in the Southern District of Florida against a broad class of anonymous e-commerce sellers identified on Schedule A. The complaint asserted 9 design patents and utility patent US8316804B2 covering pet products. The use of a ‘Schedule A’ defendant structure — listing sellers by marketplace pseudonym — is a well-established enforcement tactic against counterfeit and infringing online retailers.
The court granted an ex parte temporary restraining order (ECF No. 14) shortly after filing, authorising the restraint of defendants’ funds held by third-party platforms including Amazon. By June 6, 2025 — just 53 days after filing — the court issued a further order refining the injunction: capping restrained funds at $5,000 for defendant dechong, and extending the TRO against defendant FANGQU Co. Ltd. to facilitate settlement ahead of a June 10 hearing. Kyjen was required to notify Amazon of the order within one calendar day.
The 53-day resolution to injunction is notably fast even for Schedule A actions, suggesting strong initial pleadings and patent documentation. The $5,000 fund cap on dechong implies the court found that seller’s financial exposure warranted proportionate relief, consistent with judicial scrutiny of overbroad asset freezes. FANGQU’s ongoing TRO extension and scheduled hearing suggest at least one defendant may be pursuing negotiated resolution — an outcome the public record does not yet confirm.

Injunction granted: what the court’s order means for both parties
Ex parte TRO to preliminary injunction: a fast-track enforcement pathway
An ex parte TRO is issued without the defendant present — typically granted when a plaintiff demonstrates likelihood of success on the merits and risk of irreparable harm. In Schedule A cases, courts routinely seal filings initially to prevent defendants from dissipating assets before notice. The transition to a preliminary injunction signals the court found Kyjen’s IP claims sufficiently strong to maintain asset restraints through litigation.
Ex parte TRO → Preliminary InjunctionKyjen secures asset freeze and Amazon enforcement within 53 days
For Kyjen, the injunction effectively disrupts infringing defendants’ ability to operate and profit during litigation. The mandatory Amazon notification requirement — within one calendar day — ensures marketplace-level enforcement without delay. The proportionate $5,000 cap on dechong’s restrained funds suggests the court is balancing IP enforcement against due process, but does not weaken the overall injunctive relief Kyjen obtained.
Asset freeze + marketplace enforcementFrozen funds and looming hearings create settlement pressure on sellers
For defendants, a preliminary injunction combined with restrained marketplace funds creates acute financial pressure. The dechong cap at $5,000 shows the court will scrutinise disproportionate freezes — offering some procedural protection — but the injunction remains in force. FANGQU’s TRO extension ‘to facilitate a settlement’ is a strong signal that at least one defendant is in active resolution discussions, with a June 10 hearing as the forcing deadline.
Settlement pressure / fund restraintSchedule A tactics remain potent for pet product design patent enforcement
This case reinforces that design patent portfolios — particularly in consumer pet products — can support rapid, multi-defendant injunctive relief in S.D. Florida. The combination of design patents (ornamental) and a utility patent (US8316804B2) strengthens IP posture by covering both appearance and function. E-commerce sellers in the pet accessories space face heightened risk of fund freezes and marketplace delisting when facing a well-documented design patent portfolio asserted through Schedule A proceedings.

Official order — verbatim text
The June 6, 2025 order is procedural rather than a merits adjudication — it refines and extends injunctive relief rather than resolving liability. The $5,000 cap on dechong’s restrained funds reflects the court’s proportionality analysis under the Winter factors, suggesting Kyjen’s overall showing was strong but that per-defendant financial evidence must support each freeze amount. The FANGQU TRO extension indicates the court is actively managing settlement facilitation, consistent with S.D. Florida’s Schedule A practice norms.
USD0755446S and 9 further patents — pet product design and utility IP portfolio
Kyjen’s asserted portfolio spans 9 design patents — each protecting the ornamental appearance of specific pet product configurations — and one utility patent, US8316804B2, which protects functional aspects of pet product construction. Design patents filed under the USD series confer 15-year protection from grant date for the ornamental design of a functional item, providing a distinct enforcement tool from utility claims. The application dates span multiple years, suggesting iterative product development and deliberate IP layering across Kyjen’s pet product lines.
A portfolio of this breadth — combining ornamental and functional IP — is strategically significant in the pet accessories sector, where product differentiation often hinges on visual design. For competitors and e-commerce sellers, the layered design patent coverage means that design-arounds must avoid not just one protected appearance but multiple registered configurations. The utility patent US8316804B2 adds a functional dimension that can catch infringing products that visually differ from the design patents but replicate the underlying mechanism, raising the overall enforcement risk profile considerably.
Should you run an FTO against Kyjen’s pet product patent portfolio?
Any company designing, manufacturing, or selling pet toys, accessories, or similar consumer pet products — particularly through Amazon or other e-commerce marketplaces — should treat Kyjen’s 10-patent portfolio as a material FTO risk. The combination of 9 registered design patents and a utility patent means that visual similarity alone is insufficient to assess infringement exposure; functional features of the product must also be evaluated against US8316804B2. Given Kyjen’s demonstrated willingness to pursue ex parte TROs and asset freezes, early FTO analysis is critical before market entry.
PatSnap Eureka’s FTO Search Agent can map each of Kyjen’s 10 asserted patents against your product specifications in parallel, flagging claim overlap across both design and utility claims. Eureka’s visual similarity search is particularly effective for design patent analysis, identifying ornamental overlap that manual searches typically miss. For e-commerce teams facing Schedule A risk, Eureka also surfaces related pending applications that may extend Kyjen’s coverage — giving your legal and product teams the full IP perimeter before launch.

Portfolio viewWhat this case signals for the pet products IP enforcement landscape
Kyjen’s swift injunction underscores how design patent portfolios are weaponised against anonymous e-commerce sellers in S.D. Florida.
A broad design patent portfolio enables rapid Schedule A injunctions
Holding 9 design patents across a single product category — as Kyjen does — dramatically strengthens ex parte TRO applications. Courts are more willing to grant immediate relief when the IP scope is clear, the infringement is visually obvious, and multiple patents corroborate the claim. Pet product brands with fragmented design filings should consider consolidating coverage to replicate this enforcement posture.
Mandatory Amazon notification orders create same-day marketplace impact
The one-calendar-day Amazon notification requirement is commercially significant — it translates a court order into immediate listing takedowns and fund holds at the platform level. IP owners pursuing Schedule A actions should ensure their complaints specify third-party platform obligations explicitly to maximise the speed and scope of enforcement following an injunction.
Proportionate asset cap rulings signal judicial limits on TRO overreach
The $5,000 fund cap imposed on dechong suggests Judge Altman will scrutinise asset freeze amounts against demonstrated seller revenue. Plaintiffs in Schedule A actions should maintain granular per-defendant sales evidence to support proportionate restraint amounts — or risk court-ordered releases that may allow defendants to dissipate remaining assets before judgment.
FANGQU’s TRO extension reveals the settlement leverage mechanics of Schedule A
Extending a TRO ‘to facilitate settlement’ is a hallmark of Schedule A practice in S.D. Florida — the frozen funds effectively become the negotiating lever. IP enforcement teams should model expected settlement values against per-defendant fund exposure early, and engage with defendants who seek hearings as soon as fund restraints are confirmed, since this window is typically short.
Kyjen v Individuals — key questions answered
Kyjen asserted 10 patents: 9 design patents (USD0755446S, USD0705999S, USD0706494S, USD0706001S, USD0706000S, USD0676202S, USD0769546S, USD0833086S, USD0676619S) and one utility patent (US8316804B2), all covering pet products. The design patents protect ornamental appearances; the utility patent covers functional aspects of pet product construction.
The court granted an ex parte TRO and then a preliminary injunction, restraining defendants’ funds and ordering Amazon notification within one calendar day. For defendant dechong, restrained funds were capped at $5,000. The TRO against FANGQU Co. Ltd. was extended to June 10, 2025 to facilitate settlement. The case closed on June 6, 2025, 53 days after filing.
The court’s order does not state the specific evidentiary basis on the public record, but the $5,000 cap is consistent with S.D. Florida judicial practice of calibrating asset freezes to demonstrated per-defendant sales or revenue evidence. Courts in Schedule A cases increasingly scrutinise overbroad freezes to protect defendants’ due process rights, requiring plaintiffs to support each restraint amount with specific financial data.
A Schedule A action names defendants collectively by pseudonym (e.g. marketplace seller handles) rather than legal entity names. This allows plaintiffs to file a single action against many anonymous e-commerce sellers simultaneously, obtain ex parte TROs to freeze funds before defendants can dissipate assets, and then proceed to identify and serve each defendant individually. It is widely used in IP enforcement against online marketplaces in the Southern District of Florida.
The order required Kyjen to notify Amazon of the preliminary injunction within one calendar day of entry. In practice, this translates the court order into platform-level action: Amazon is obligated to restrict the listed sellers’ accounts, freeze their funds held in marketplace accounts, and potentially remove infringing listings. This mechanism makes judicial relief operationally effective without requiring individual service on each anonymous defendant.
