Inside improper joinder of defendants: the seller's real options

A federal order freezes a seller's Amazon account and payment balances before they ever see the complaint. By the time the seller learns what has happened, a temporary restraining order is already in place, a bond has been posted, and their store is effectively dark. The notice arrives not through ordinary service but through Amazon's own notification system – and the seller discovers, buried in the case caption, that they are one of dozens or even hundreds of defendants named together in a single action.

TL;DRImproper joinder of defendants is a structural defect in Schedule A litigation: a plaintiff bundles large numbers of unrelated sellers into one case to preserve a single filing fee and a single sealed TRO, even though the sellers share no transaction, no agreement, and no common conduct. That bundling is legally contestable, and challenging it is often the first and most consequential move an affected seller can make.

This analysis works through the mechanics of improper joinder, the procedural path once a seller is named, the real decision points and their trade-offs, and the practical reality of litigating or settling in this environment. It is written for sellers and their in-house teams who have received a TRO notice and need to understand what they are actually dealing with.

What is improper joinder of defendants in a Schedule A case?

Joinder of defendants is improper when the claims against each seller do not arise from the same transaction or occurrence and do not share a common question of law or fact – the two requirements the Federal Rules of Civil Procedure set for permissive joinder. In Schedule A litigation, the mechanics of the SAD scheme make improper joinder almost structurally inevitable.

The plaintiff – typically a brand owner or a litigation-finance-backed IP firm – identifies a set of online stores, often scraped from marketplace search results. The stores may sell in the same product category. Beyond that, however, they have nothing in common. Seller A operates from a registered US entity. Seller B is an overseas seller with no US presence. Seller C has sold two units of a product. Seller D has sold thousands. They do not know each other, did not source from the same supplier, and took no coordinated action. What they share is only that the plaintiff has alleged infringement by each of them.

Courts have long recognized that this pattern does not satisfy the same-transaction-or-occurrence requirement. The leading challenge is straightforward: separate sales by separate sellers, of separately sourced goods, to separate customers, on separate occasions, do not constitute the same transaction. The plaintiff's theory is that the "scheme" of infringement is the common thread. That argument is weak when the sellers are genuinely independent actors. In matters we handle, the joinder defect is one of the first things we assess, because severing the action early changes the economics of the entire case.

Why does it matter in practice? A single mega-case lets the plaintiff obtain a single TRO covering all defendants simultaneously, freeze all of their funds in one order, and complete that process before any defendant is served. The moment the action is severed into individual cases, the plaintiff faces separate filing fees, separate bond requirements in some courts, and separate courts in some scenarios. The cost structure of mass-joinder litigation collapses when each defendant is isolated.

Federal Rule of Civil Procedure 20(a)(2) is the operative rule: defendants may be joined in one action only if (i) any right to relief is asserted against them jointly, severally, or arising out of the same transaction or occurrence, and (ii) a question of law or fact common to all defendants arises in the action. Schedule A complaints routinely fail both prongs when the defendants are genuinely unrelated sellers.

How does the SAD scheme work and why does joinder make it effective?

The SAD scheme – Schedule A Defendants litigation – is a volume-driven IP enforcement model that has drawn significant judicial scrutiny in recent years. Understanding its mechanics is essential to understanding why challenging joinder is worthwhile and what the plaintiff is actually trying to accomplish.

The plaintiff files a sealed complaint, usually in a federal district court with a favorable reputation for ex parte TRO grants. The complaint names a Schedule A list of defendants – the sellers and their store names – rather than identifying each by name in the caption. Because the complaint is sealed, the defendants cannot learn they are being sued until the TRO issues. The TRO instructs Amazon, PayPal, and other platforms to freeze the defendants' accounts and funds. Amazon then notifies the sellers that their accounts are restricted due to a court order.

The joinder device is central to the scheme's economics. A single filing fee covers all defendants. A single sealed hearing is faster and cheaper than dozens of individual applications. A single TRO freezes all funds at once, creating maximum settlement pressure before any defendant even has a lawyer. When a seller's entire operating balance is frozen and their store is offline, the rational short-term calculation is to pay whatever the plaintiff's demand is and move on – regardless of whether the underlying infringement claim is meritorious.

In our practice, we regularly see sellers who received a settlement demand within days of the freeze, before they had any realistic ability to assess the strength of the claim. That is not coincidence. The scheme depends on settlement before the merits are ever tested. Challenging joinder disrupts this timeline – and that disruption is exactly what the plaintiff does not want.

What has changed is that a growing number of federal courts have grown skeptical of these mega-cases. Some courts have begun requiring plaintiffs to show, at the outset, why the defendants are properly joined. Others have sua sponte severed cases or ordered briefing on joinder. That judicial shift is an important development for sellers who are willing to appear and contest.

What does contesting improper joinder actually require?

Contesting improper joinder requires the seller to appear in the case. That step carries its own consequences, and it is where many sellers make their first significant error. Appearing pro se – without counsel – in a federal IP case while a TRO is in place is rarely advisable. The procedural pace is fast, the filings are technical, and a badly timed or misdirected submission can waive defenses or accelerate a default.

The primary mechanism for raising misjoinder is a motion under Federal Rule of Civil Procedure 21, which allows the court to sever defendants and add or drop parties at any time. The motion argues that the same-transaction-or-occurrence requirement is not met; that any common questions of fact or law are insufficient to override the prejudice to individual defendants from being tried together; and that severance is the appropriate remedy. In some courts, the motion is joined with a motion to dissolve or modify the TRO as to the moving defendant, on the grounds that the TRO was obtained based on an improperly joined complaint.

Timing is the first decision the seller must make. The TRO typically lasts only a limited number of days before the plaintiff must either obtain a preliminary injunction or allow the freeze to expire. That deadline creates pressure in both directions: the seller needs to appear quickly enough to contest the preliminary injunction, but not so quickly that they waive defenses they haven't had time to assess. We review the specific TRO language, its expiration date, and the preliminary injunction schedule before advising on when and how to appear.

The motion itself must be grounded in the actual facts of the seller's situation. A generic argument that "all Schedule A cases are improperly joined" will not move a court. The motion must explain why this particular seller's conduct is unrelated to the other defendants, why the plaintiff's "common scheme" theory fails on these specific facts, and why severance rather than dismissal is or is not the right remedy. Some sellers are strong candidates for dismissal on jurisdiction or venue grounds once severed. Others are better served by negotiating from a severed position.

For sellers who sourced legitimately and have documentation – invoices, authorization agreements, brand relationships – the motion to sever can be paired with a substantive defense on the merits. For sellers who are less certain about their supply chain, the motion still changes the economic dynamic of the case even if the merits defense is thin.

What are the realistic procedural routes and their trade-offs?

Once a seller is in a Schedule A case, the realistic options fall into several paths. None of them is consequence-free. The choice depends on the strength of the infringement claim, the amount frozen, the seller's supply chain documentation, and their appetite for litigation. In matters we handle, we work through each variable before recommending a direction.

The first path is to appear and contest. The seller files a notice of appearance, moves to dissolve or modify the TRO, and simultaneously moves to sever. If the joinder motion is granted, the seller is in their own case – at which point the plaintiff faces the cost-benefit of pursuing a single defendant. Plaintiffs in these matters are often litigation-finance operations, and the economics of pursuing one well-defended small seller in a standalone case may not work. In our experience, appearances followed by credible procedural motions often accelerate a settlement conversation on terms far better than the initial demand.

The second path is to settle early. Some sellers, particularly those with thin supply-chain documentation or small account balances, rationally choose to pay the settlement demand, have the freeze lifted, and return to selling. That decision is not a failure. It is a business judgment. The risk is paying a settlement to a plaintiff whose underlying claim is weak – which encourages more of the same litigation against the same or other sellers.

The third path – doing nothing – is the worst outcome in nearly every scenario. Default judgment in federal court is a real possibility for sellers who ignore the notice. A default judgment can be substantially larger than any settlement demand, and once entered, it can be enforced against assets beyond the platform balance. If the seller's account is already frozen, a default judgment may convert a temporary freeze into a permanent loss. For details on how the initial sealed complaint process works and what happens when a case becomes public, the analysis at de-anonymizing a Schedule A complaint explains the unsealing mechanics and what they mean for the seller's account.

A fourth scenario applies to sellers whose business operates across multiple platforms. A TRO in a US federal Schedule A case typically names the specific stores identified by the plaintiff. If those stores operate on Amazon US but the seller also operates on other platforms – including Etsy or eBay – the scope of the freeze and the reach of the injunction may differ. For sellers with cross-platform exposure, the analysis at sealed complaints against online stores and Etsy accounts is relevant context.

The decision matrix in practical terms: if the frozen balance is below the cost of litigation, early settlement may be the correct answer even on a weak claim. If the balance is significant, or if the seller's business model depends on the affected store, contesting is almost always worth a professional assessment of the motion's strength. If the claim is demonstrably unfounded – the seller has a valid license, or the product is not infringing – contesting is almost always the right answer, regardless of the amount frozen.

Jurisdiction, personal jurisdiction, and what severance can expose

Improper joinder is not the only structural argument available to a seller once they appear. Personal jurisdiction – whether the court can legally exercise power over this specific seller – is a separate and often powerful defense, particularly for overseas sellers or US-based sellers with no meaningful contact with the district where the case was filed.

Many Schedule A cases are filed in a small number of federal districts regardless of where any defendant is located. A seller based in another US state, or outside the US entirely, may have no business connection to the filing district. Once the case is severed, the personal jurisdiction challenge becomes viable for individual defendants in a way it often is not when defendants are bundled together and the motion to sever hasn't been made.

We regularly assess personal jurisdiction alongside joinder in the initial review. The two arguments can work together: the court should sever the cases, and once severed, this particular defendant should be dismissed for lack of personal jurisdiction. Courts that grant severance sometimes also grant motions to transfer or dismiss based on jurisdiction. That outcome – dismissal without any merits decision on the infringement claim – is often the best result available to a seller who was improperly brought into a distant court.

Venue is a related consideration. Even where personal jurisdiction technically exists, improper venue can be grounds for transfer to a more favorable district. A seller whose entire customer base and operations are in one region, sued in a district with no connection to the dispute, has a plausible venue challenge. These arguments are technically demanding, but in the right factual setting they significantly alter the litigation dynamic.

The broader point is that improper joinder opens a set of procedural doors that are closed if the seller does nothing. Each door leads to a different path with a different cost and a different probability. One of the first things we do in a new Schedule A matter is map which doors are open for that specific seller, based on the actual facts of their business and the specific court and judge involved.

Common mistakes sellers make when handling this alone

The first and most damaging mistake is waiting. The TRO has a fixed duration. The schedule for a preliminary injunction hearing moves fast. A seller who spends the first two weeks reading forum posts and contacting their platform's seller support has almost certainly missed the optimal window to contest the TRO or file a notice of appearance that changes the litigation dynamic.

The second mistake is contacting the plaintiff's counsel without legal advice. That contact is often used by plaintiffs as a signal that the seller will settle. Initial demands are almost always negotiable, but a seller who opens a conversation without representation has already revealed their hand and often their desperation. The plaintiff's counsel is not a neutral party. Their job is to maximize recovery for their client.

The third mistake is conflating the Amazon account restriction with the legal case. The account freeze is a consequence of the TRO. Resolving the account status – getting the store back online and the funds released – requires engaging the legal case, not just submitting appeals through Seller Central. Account Health and Seller Central tools have no mechanism for lifting a court-ordered freeze. Only the court does. Sellers who spend their energy on Seller Central rather than the case itself often watch the TRO convert into a preliminary injunction while the account remains frozen.

A fourth mistake applies to sellers who operate related accounts. In matters we handle, we sometimes encounter sellers who, believing one account is frozen, attempt to sell through a related or secondary account. That conduct, if discovered, can dramatically widen the plaintiff's claims and the scope of any injunction. It can also create account-level problems with Amazon that are entirely separate from the court case and harder to resolve. The complete overview of Schedule A litigation from the initial complaint through resolution is at Schedule A TRO defense: the complete guide for sellers.

What does a joinder challenge actually look like in practice?

Consider an electronics accessories seller operating on Amazon US. In fall 2026, they received an account restriction notice from Amazon citing a court order. The complaint – once the seller located it through the court's docketing system – named over 200 defendants. The seller was listed under their store name, which had been identified through a marketplace search. Their balance was frozen. The settlement demand from plaintiff's counsel arrived within several days, citing trademark infringement.

We reviewed the deactivation notice, the TRO, and the complaint. Three things were immediately apparent: the seller had purchased their inventory through a legitimate distributor, had documentation for those purchases, and had no connection to any other defendant in the case. The same-transaction-or-occurrence requirement was not met. We filed a notice of appearance, moved to sever the defendant, and simultaneously moved to modify the TRO on the grounds that the plaintiff had made no showing of likely success on the merits as to this specific seller.

The motion to sever was granted. Once severed, the plaintiff had to decide whether to pursue a single well-documented defendant in a standalone case. They returned to the settlement table at a fraction of the original demand. The seller's account was restored as part of the settlement and compliance with the court's order dissolving the injunction. The outcome was qualitatively far better than the original demand – and far better than the default that would have resulted from inaction.

A second situation – different surface, different period – involved a home goods seller on Amazon US (spring 2027) who had been named in a copyright-based Schedule A complaint. The seller had no US business entity and operated exclusively through a marketplace account. After the TRO issued, the seller contacted us. We assessed personal jurisdiction: the seller had made no sales to customers in the filing district and had no other contact with that court. We filed a motion to sever and, simultaneously, a motion to dismiss for lack of personal jurisdiction. The court granted severance and, in the individual case, granted dismissal on jurisdiction grounds. No settlement was paid.

These examples illustrate the range of outcomes that procedural challenges can produce. They are not guarantees. Each case turns on its specific facts, the specific court, and the specific judge. What they demonstrate is that contesting – with properly prepared motions grounded in the facts of the individual seller's situation – changes the range of realistic outcomes available.

The objection most sellers believe, and why it is wrong

The most common myth we encounter is that being named in a Schedule A case is effectively the end of the matter – that a federal complaint means the plaintiff wins, the account is gone, and the only question is how much to pay. That belief is exactly what the SAD scheme depends on. It is the mechanism by which volume-litigation practices extract settlements from sellers regardless of the strength of the underlying claim.

Federal litigation has procedural safeguards that exist precisely to prevent this. The requirements for joinder, personal jurisdiction, venue, and the merits of a TRO application are real legal standards that courts apply and that sellers can invoke. A TRO is not a final judgment. It is a preliminary order issued without a full hearing, and it is explicitly subject to modification and dissolution on motion. A plaintiff who could not show the same result would obtain at a full preliminary injunction hearing has obtained a TRO that should not survive scrutiny.

What makes the myth persistent is that most sellers in Schedule A cases do not appear and contest. They settle, or they default. The subset that appears and files credible motions often produces very different results. That sample is underreported because settlements are confidential and dismissals do not generate headlines. The realistic picture – that procedural challenges work when the facts support them – is not what the plaintiff's form letter implies.

We review the TRO, the complaint, and the seller's account situation before advising on which arguments are available and what the cost-benefit looks like for this particular matter. That is what a proper assessment looks like: not a generic promise that the case can be won, but an honest read of what is open, what it costs to pursue it, and what the realistic range of outcomes is.

If a first appearance or a settlement approach already produced an unfavorable result, a second read of the case can identify what arguments have been waived, what is still open, and whether there is a basis to reopen or appeal.

Frequently asked questions

How long does resolving improper joinder of defendants usually take on Amazon US?

The timeline varies considerably depending on the court, the judge, and whether the plaintiff contests the severance motion. A motion to sever is typically briefed and decided within several weeks of filing, assuming the seller appears promptly. The TRO itself has a short duration – usually measured in days from issuance before a preliminary injunction hearing is required. Sellers who appear quickly and file credible motions are better positioned to influence the timeline. Once severed, the individual case may settle, proceed to preliminary injunction briefing, or be dismissed on jurisdiction grounds, each of which carries its own schedule. The honest answer is that early action compresses the timeline; delay almost always extends it and narrows the options.

What are the main risks if I handle improper joinder of defendants alone?

The primary risk is missing critical deadlines. Federal civil procedure has fixed timelines for responding to TROs, appearing, and contesting preliminary injunctions. A seller who misses these windows may default or inadvertently waive defenses. A second risk is making procedural missteps that actually harm the case – filing in the wrong court, responding to the wrong motion, or contacting plaintiff's counsel in a way that undermines settlement leverage. Misjoinder arguments are legally technical; a generic motion is unlikely to be persuasive. Finally, sellers without counsel often cannot assess accurately whether a claim has real merit, which means they may settle claims they could have won or fight claims they should have settled.

Do I need a lawyer for improper joinder of defendants?

Not legally required, but in practice the answer is almost always yes. A joinder challenge in a federal IP case is a technical procedural motion in a court that expects citations to case law and proper procedural framing. Sellers appearing pro se in these cases are at a structural disadvantage: the plaintiff's counsel has handled many of these cases; the judge has seen many of them; a pro se motion that does not engage the legal standard will be rejected. Beyond the motion itself, a lawyer can assess whether personal jurisdiction or venue challenges are available, evaluate the merits of the underlying claim, and negotiate from a position of knowledge. The cost of representation is almost always justified when weighed against the amount frozen and the alternative outcomes.
