Served through a marketplace platform: a seller's primer

TL;DRBeing served through a marketplace platform – specifically through eBay – means a US federal court has allowed a plaintiff to deliver lawsuit papers to you via the platform itself, often as part of a "Schedule A" complaint targeting dozens or hundreds of sellers at once. A temporary restraining order (TRO) freezing your eBay funds may already be in place before you learn the case exists. Being named does not mean you have lost; it means the clock is running, and the decisions made in the first days carry the most weight.

The notice arrives inside your eBay Seller Hub, or you discover your payout account is frozen and then find the notice. Either way, the sequence is the same: a US federal court in Chicago or another jurisdiction with a busy intellectual-property docket has entered an emergency order, a plaintiff's lawyer has served you through the platform under that order's authorization, and your money may already be gone from the account.

That is a real federal lawsuit. It carries real consequences – a potential default judgment, a permanent injunction, and a damages award – if it goes unanswered. Understanding what is actually happening procedurally, what your options are, and what the decision points look like is the purpose of this page.

What does "served through a marketplace platform" actually mean on eBay?

Service through a marketplace platform is a court-authorized method of delivering a summons and complaint to defendants whose physical addresses are unknown or disputed. In Schedule A cases, plaintiffs typically file a complaint naming a large number of sellers identified only by their platform seller handle, then ask the court to authorize alternative service – including service through the platform's messaging or seller interface.

On eBay specifically, this often means the court order directs eBay to relay the service documents to the seller's registered account, or it authorizes service by email to the address associated with the account. The seller may not see it immediately, particularly if they do not monitor messages in Seller Hub closely. That delay does not pause the response clock.

The Schedule A format – named after the sealed exhibit listing all defendants – is used almost exclusively in trademark and copyright infringement cases, most frequently in the Northern District of Illinois. Plaintiffs argue that sellers on online marketplaces form a common enterprise of infringement and can therefore be joined in a single action. That joinder theory is contested and has been successfully challenged in a number of matters; it is one of the first things worth examining.

What makes this model particularly aggressive is the TRO stage. Before defendants are served at all, the plaintiff asks the court to freeze the defendants' marketplace accounts and associated payment accounts, on the grounds that defendants who know about the case might transfer funds offshore. The order often issues ex parte – meaning without any notice to you. By the time service reaches your eBay account, your available balance may already show zero or pending review.

In matters we handle, sellers frequently describe discovering the freeze before they see the lawsuit itself. They log in expecting to process a withdrawal and find the account locked. The instinct to contact eBay's seller support to ask what happened is understandable, but it does not address the underlying court order – which is where the problem actually lives. You can read more background on the broader mechanism in our Schedule A / TRO defense complete guide for sellers.

What happens procedurally after you are served?

From the moment valid service is accomplished, the Federal Rules of Civil Procedure impose a response deadline – typically 21 days for defendants served within the United States. Missing that deadline without an extension allows the plaintiff to seek a default judgment, which can translate into a damages award entered against you without any hearing on the merits.

The procedural sequence in a typical Schedule A matter runs roughly as follows. First, the TRO is entered, often sealing the complaint and the defendant list while the freeze is put in place. Second, the plaintiff serves defendants through the platform or by email. Third, the court schedules a preliminary injunction hearing, usually within a couple of weeks of the TRO. Fourth, defendants who have appeared in the case can contest the preliminary injunction and seek to dissolve or narrow the asset freeze at that hearing.

Appearing in the case – formally entering a notice of appearance and filing a response or motion – is the mechanism that gives you a voice at the preliminary injunction stage. Sellers who do nothing have no standing to contest the freeze at that hearing. The freeze simply converts from a TRO into a preliminary injunction, which holds until the case is resolved or a separate motion is filed later.

After the preliminary injunction stage, the case typically moves toward either settlement or, less commonly, full litigation. In practice, most Schedule A matters resolve at the settlement stage, once the parties have exchanged some information and the defendant has had an opportunity to challenge the scope of the asset freeze. But "settlement" in this context does not mean the plaintiff automatically makes a reasonable offer. Settlement terms depend heavily on how the defendant has positioned themselves procedurally – whether they have appeared, whether they have filed a motion to dissolve or modify the TRO, and whether they have challenged jurisdiction or joinder.

One point that matters a great deal on eBay specifically: eBay's cooperation with court orders covering frozen funds is extensive. The platform will typically comply with a court-issued freeze and will not release funds during the pendency of the order, regardless of any seller support ticket. The path to unfreezing runs through the federal court, not through eBay. Our separate piece on frozen PayPal and marketplace funds covers what sellers should understand about the broader mechanics of payment freezes in these situations.

What is the SAD scheme and why does it matter for eBay sellers?

The "SAD scheme" – an acronym sometimes used in court filings and in commentary on this litigation model – refers to the practice of using Schedule A Defendants complaints as a mechanism to rapidly obtain ex parte TROs and asset freezes across large numbers of marketplace sellers, many of whom may have legitimate defenses or may have been joined questionably.

Courts in recent years have scrutinized the joinder theories used in these cases more carefully. The argument that dozens of unrelated sellers operating under separate eBay accounts should be treated as part of a common scheme is legally contestable, and challenges on misjoinder grounds have in some matters led courts to sever cases or question their own jurisdiction over foreign-based defendants. If you are an international seller operating on eBay's US marketplace, personal jurisdiction is a threshold question that can sometimes short-circuit the case before it reaches the merits.

Why does this matter practically? Because if joinder is improper or jurisdiction is absent, the TRO issued on the back of those flawed premises may be vulnerable to dissolution. That means the asset freeze may be lifted without a full merits fight, which is often the better outcome for a seller whose primary concern is accessing frozen funds and returning to business. We work to identify these leverage points early, before the preliminary injunction hearing closes the window.

It also matters because the SAD model has attracted criticism from courts and commentators, and some plaintiffs now file these cases with more attention to which defendants genuinely belong together. As a named defendant, you are not simply a passive recipient of whatever order the court entered. You have the right to be heard, and the quality of that appearance determines the shape of everything that follows.

What are your real decision points once you are served?

The decisions a seller faces in the first days of a Schedule A matter are not all obvious, and getting them wrong narrows the options later. Here are the real choice points, in order.

Appear or default. Defaulting – doing nothing – is almost always the wrong choice. A default judgment can include enhanced damages under the Lanham Act, potentially reaching into significant dollar figures, plus a permanent injunction. Even if you believe the complaint is entirely baseless, appearing preserves every defense you have; defaulting forfeits them.

Move to dissolve or narrow the TRO, or wait for the preliminary injunction hearing. If the TRO was entered on a misrepresentation, on insufficient evidence, or under a joinder theory that does not hold for your account, a motion to dissolve or modify is available. In many matters, that motion – or the credible threat of filing it – creates negotiating room. The timeline is tight: the TRO typically expires unless the court converts it to a preliminary injunction, and the hearing on that conversion is where the leverage is highest.

Challenge jurisdiction or joinder early or as part of an answer. If personal jurisdiction is absent – common for sellers based outside the US whose only US connection is a marketplace account – that is a defense worth raising promptly. Joinder challenges can also be raised at the outset. Neither is a silver bullet, but both are tools that legitimately force the plaintiff to justify the structure of the case.

Evaluate the merits of the underlying IP claim. Not every Schedule A complaint reflects a valid trademark or copyright. Sellers who have legitimate authorization – a genuine license, a supply chain that traces to an authorized distributor, or a product that does not actually infringe the registered mark – have substantive defenses. Evidence of authorization or legitimate sourcing should be gathered immediately, before it becomes harder to reconstruct.

Open settlement discussions. Most of these cases settle. The terms depend on position. A defendant who has appeared, filed a motion, and put the plaintiff on notice that they will contest jurisdiction and joinder is in a materially different negotiating position than one who has been silent. Settlement figures in these cases can range from nominal to substantial, and the range is wide enough that legal guidance on value and tactics is genuinely important.

A home-goods eBay seller (summer 2025) received a platform notice identifying an asset freeze tied to a Schedule A trademark complaint. The seller had a verifiable supply chain from a US-authorized distributor and had done no business under the alleged infringing mark. We reviewed the complaint, confirmed the joinder involved unrelated sellers, filed an appearance and a targeted motion raising joinder and authorization, and reached a settlement that released the frozen balance and dismissed the claims against our client. The case illustrates the gap between default outcomes and what is possible with a prompt, grounded response.

What should you do in the first 48 hours?

Speed matters, but calm and deliberate action matters more than frantic speed. Here is the sequence that makes the most difference.

First, identify the case. The service documents – whether they arrived in your eBay inbox, by email, or otherwise – will reference a court, a case caption, and a plaintiff. Look it up on PACER (the US federal court records system) to confirm what has been filed and when. This tells you the actual deadline you are facing and the judge assigned to the matter.

Second, preserve records. Document your eBay account standing, your inventory, your sourcing records, your supplier invoices, any licenses or authorization letters, and any correspondence that bears on the product or mark at issue. The sooner this is organized, the stronger any defense or settlement position becomes.

Third, do not contact the plaintiff's attorney without counsel. Anything you say can be used to shape the case against you. Plaintiff's counsel in Schedule A cases is experienced at these matters; unrepresented sellers frequently say things that inadvertently confirm allegations or limit their defenses. A brief, professional email through counsel later is almost always better than an unfiltered conversation now.

Fourth, get a legal read on the notice, the TRO, and the complaint. Not necessarily a full engagement, but enough to understand whether the freeze is lawful on its face, whether there is a misjoinder argument, whether a motion to dissolve makes sense on the timeline, and what the realistic settlement range looks like. That read shapes everything else.

In matters we handle, sellers who act within the first few days consistently have more options available than those who wait a week or more. The preliminary injunction hearing does not move for late-arriving defendants. The window is real.

Does being named in a Schedule A case mean you have already lost?

Being named in a Schedule A complaint is not a finding of liability. Courts have not evaluated the merits of the underlying claim when they enter a TRO; they have evaluated the plaintiff's showing of immediate irreparable harm and the balance of hardships on an emergency, one-sided basis. That is a low bar for an initial freeze – but it is not a finding of infringement.

A significant share of sellers named in these cases have legitimate defenses. Misidentification is not rare: some sellers are added to Schedule A lists based on automated review of listings that surface false positives, or because their product falls near but not within the plaintiff's registered mark. Others were genuinely operating within authorized channels and the complaint fails to reflect that. Still others have real joinder problems that undermine the court's basis for entering any order against them at all.

The myth worth confronting directly is that being named means you are guilty and settling is your only option. Settlement is often the practical resolution, but it should be entered on informed terms – with an understanding of what the complaint actually says, what defenses are available, what the realistic range of outcomes is, and whether the plaintiff's mark and the alleged infringement are as clear as the TRO papers suggest. Attorney-led review of the complaint and the freeze order is the starting point for that analysis.

We regularly see sellers who assumed they had no options and who had in fact strong arguments they never raised. The cost of raising them – a motion, an appearance, a negotiation – is typically far less than the cost of a default judgment or a settlement entered from a position of ignorance.

If you have received a platform notice and are unsure whether it constitutes valid service or what steps to take before consulting a lawyer, the safe default is to treat any court-related notice as real and urgent. The cost of overreacting to a real federal order is negligible. The cost of underreacting to one is not.

Frequently asked questions

How long does resolving served through a marketplace platform usually take on eBay?

Resolution timelines vary significantly depending on how the defendant responds and how quickly settlement discussions progress. A case where the defendant appears promptly, files a motion, and opens negotiations can reach a settlement in weeks. A case that goes to full merits litigation can take considerably longer – many months to over a year. The preliminary injunction hearing typically occurs within two to three weeks of the TRO, which is the first major procedural inflection point. Most Schedule A matters on eBay that we have handled resolve before full discovery, but the seller's posture in the first weeks heavily influences the timeline. Doing nothing almost always extends the process and weakens the outcome.

What are the main risks if I handle served through a marketplace platform alone?

The primary risk is a default judgment – a damages award entered against you, potentially under the Lanham Act's enhanced damages provisions, without any hearing on the merits. Beyond that, unrepresented sellers frequently miss the preliminary injunction hearing without having appeared, meaning the freeze becomes entrenched with no challenge on the record. Sellers who do contact plaintiff's counsel without representation often make admissions or concessions that narrow their defenses before they understand what those defenses are. The asset freeze may also remain in place longer than necessary if no motion to dissolve or modify is filed. These are procedural risks, not abstract ones – they are the predictable consequences of inaction or uninformed action in a federal litigation context.

Do I need a lawyer for served through a marketplace platform?

For a matter that involves a federal court, an ex parte TRO, a frozen eBay balance, and a complaint carrying potential enhanced damages, the practical answer is yes. The procedural steps – appearing, filing motions, contesting the freeze, negotiating settlement – all require understanding federal civil procedure and trademark law well enough to use them tactically. What varies is the scope of engagement needed: some sellers need full representation through settlement, others need a scoping review and targeted motions only. A short initial review of the complaint and the TRO order is enough to understand what level of involvement makes sense for your specific situation. The fee for that review is fixed and quoted up front.
