An American company spends two years litigating a patent case against a Shenzhen manufacturer. It wins. It walks out of the courthouse with a substantial judgment in hand. And then it discovers that the judgment is worth precisely nothing--because the Chinese court asked to enforce it refuses, on the ground that the defendant was never properly served under the Hague Service Convention. Two years of fees, expert reports, and motion practice, all undone by a step that happened before the case really began.

That is the nightmare. Here is the one that is far more common, and far more fixable: a brand discovers two hundred storefronts on a marketplace selling counterfeits of its product, all routing money back to China through Alipay and platform-held balances. If it files quietly, gets an ex parte order freezing those balances before anyone is served, and serves the anonymous sellers by email under a court order, it can have the counterfeiters' cash locked down within a week. If it telegraphs the suit first--or fumbles the service order--the money is wired home overnight and the storefronts reincarnate under new names by the weekend. Same defendants, same infringement, wildly different outcomes. The difference is almost entirely a matter of how you serve and how fast you move.

This is the intellectual-property litigator's version of the service problem, and it is a different animal from the general challenge of getting papers to a defendant in China. Our companion piece, Serving Defendants in China: Methods and Strategy Under the Hague Service Convention, is the place to start if you want the full anatomy of the Central Authority channel, the team you need to assemble, and the mechanics of the USM-94 package. This article assumes that foundation and builds the floor above it: the remedies, procedural maneuvers, and ex parte tools that turn a service problem into an enforcement strategy. We cover the "Schedule A" model that has reshaped brand enforcement, the doctrine of court-ordered email service under Rule 4(f)(3), the Rule 65 machinery that freezes a defendant's money on day one, the Defend Trade Secrets Act's extraordinary civil seizure remedy, anti-suit injunctions deployed against Chinese-court interference in patent wars, and what China's 2024 Civil Procedure Law means for collecting on the judgment you fight to win.

We define the terms of art as we go, so a judge, a litigator, and a curious general counsel can all follow along. And we keep one principle in front of us throughout: in cross-border IP litigation, service is not paperwork. It is the first move in a fight where the other side's opening play is, predictably, to attack the way you served them.

First Principles: Why Service Decides Everything Downstream

Before China, a quick foundation, because the entire problem flows from it.

"Service of process" is the formal legal act of delivering the case-initiating documents--the summons and complaint--to a defendant. It is not casual notice. It is the constitutional and jurisdictional event that does two things at once. First, it satisfies due process: the Fifth and Fourteenth Amendments require "notice reasonably calculated, under all the circumstances, to apprise interested parties of the pendency of the action," the standard the Supreme Court set in Mullane v. Central Hanover Bank & Trust Co., 339 U.S. 306, 314 (1950). Second, valid service is the trigger that vests the court with personal jurisdiction over the defendant--the power to bind that party with a judgment. A court cannot proceed against a defendant it has not properly served.

For the IP plaintiff, that second point is where dreams go to die. A court may have all the personal-jurisdiction "contacts" in the world--the Chinese manufacturer may sell millions of dollars of infringing widgets into the forum state--but if the defendant was never served in a manner the law recognizes, the court has no power to enter a judgment that survives challenge. A defendant who was never properly served can attack the resulting "judgment" as void: directly on appeal, collaterally under Federal Rule of Civil Procedure 60(b)(4), or--most painfully--when the judgment-creditor tries to enforce it abroad. The first line of any sophisticated defense brief filed by Chinese counsel is a challenge to service.

Now layer in the feature that distinguishes IP cases from ordinary cross-border disputes: the remedy you actually want often arrives long before final judgment. In a counterfeiting case, the prize is frequently the asset freeze and the platform deactivation, not the eventual default damages award. In a patent case, it may be a preliminary injunction that stops the infringing imports. In a trade-secret case, it may be a seizure order that captures the misappropriated data before it propagates. Every one of those remedies depends on the same fragile foundation--proper service--and several of them must be obtained ex parte, before the defendant has any chance to react. That collision, between the slow certainty of Hague service and the urgent ex parte relief IP plaintiffs need, is the central tension of this entire field. For the broader architecture of how these documents enter a federal case, see Navigating the Paper Trail: A Comprehensive Guide to Federal Civil Litigation Filings, and for the strategic frame, Global Patent Litigation Strategies.

The Rules of the Road: FRCP 4, the Hague Convention, and the Doors Between Them

Most U.S. IP cases against Chinese defendants live in federal court--patent and federal copyright claims arise under federal law, and Lanham Act trademark and false-advertising claims do too. So the governing rule is Federal Rule of Civil Procedure 4, and within it, two subsections do almost all the work.

Rule 4(f) authorizes service on an individual abroad by one of three routes: (1) "any internationally agreed means" such as the Hague Convention; (2) absent or beyond an international agreement, methods such as those prescribed by the foreign country's law or directed by a letter rogatory, or, unless the foreign country forbids it, personal delivery or clerk-dispatched mail with a signed receipt; and (3)--the one that matters most here--"by other means not prohibited by international agreement, as the court orders." Because most Chinese IP defendants are companies, Rule 4(h)(2) is usually the operative provision; it incorporates Rule 4(f)'s methods (excepting in-hand personal delivery) for serving entities abroad. When you read "Rule 4(f)(3)" below, understand it reaches Chinese corporate defendants through Rule 4(h)(2).

Three structural features matter enormously, and all three are routinely misunderstood.

First, the subsections of Rule 4(f) are not a hierarchy. A plaintiff need not attempt Central Authority service and fail before turning to court-ordered alternative service under 4(f)(3). The Ninth Circuit said so squarely in Rio Properties, Inc. v. Rio International Interlink, 284 F.3d 1007, 1015 (9th Cir. 2002), holding that Rule 4(f)(3) "is neither a last resort nor extraordinary relief" but "merely one means among several." Many district courts nationwide follow Rio. Some, exercising discretion, do want a showing that the plaintiff first tried the Convention or that doing so would be futile--but that is a discretionary gloss, not a rule. This is the doorway through which both email service and Schedule A practice walk.

Second, Rule 4(m)'s deadline does not run against you abroad. The 90-day service clock expressly excludes service on a foreign corporation, partnership, or association in a foreign country. That is a quiet mercy for plaintiffs facing a year-long Central Authority slog--but courts still expect diligence, and after roughly six months of Central Authority silence, the advisory committee's note to the 1993 amendment and cases like SEC v. Shehyn, 2008 WL 6150322, at *3 (S.D.N.Y. Nov. 26, 2008), supply the hook to move for alternative service under 4(f)(3).

Third, the Hague Service Convention, where it applies, is not optional. That is the hinge of everything, and the next section.

The Hague Convention: Mandatory Where It Applies, and the Three Doors Out

The Convention on the Service Abroad of Judicial and Extrajudicial Documents in Civil or Commercial Matters--concluded at The Hague on November 15, 1965 (20 U.S.T. 361, T.I.A.S. No. 6638)--is the primary treaty governing cross-border transmission of legal documents. The United States ratified in 1969; China acceded in 1991, with entry into force on January 1, 1992. Its central innovation is the Central Authority: a single government body each member designates to receive incoming requests, route them through its domestic system, effect service under local law, and return a certificate. For China, that body is the Bureau of International Judicial Assistance, Ministry of Justice, in Beijing.

The critical doctrine is exclusivity. In Volkswagenwerk Aktiengesellschaft v. Schlunk, 486 U.S. 694, 699 (1988), the Supreme Court held that "compliance with the Convention is mandatory in all cases to which it applies," and that by operation of the Supremacy Clause it preempts inconsistent service methods. China's own Civil Procedure Law reinforces the point from the other side: it does not recognize service effected within China by foreign methods that bypass the treaty machinery China agreed to. The companion treaty observation is worth flagging too--the Convention governs only the initial service of process, not subsequent judicial documents, a distinction courts have drawn repeatedly (see, e.g., Trade Well Int'l v. United Cent. Bank, 2014 WL 4546022, at *2 (W.D. Wis. Sept. 12, 2014)).

So if you are serving a defendant physically located in mainland China and the Convention applies, you must comply. Mailing the summons, emailing it, or sending a U.S. process server into a Shenzhen office is not merely inadvisable--it can void your judgment.

But Schlunk itself supplies the subtlety that drives nearly every workaround in IP practice. The Convention applies, by Article 1, only "where there is occasion to transmit a judicial or extrajudicial document for service abroad"--and whether there is such an occasion is answered by the law of the forum, not by the Convention. The treaty specifies how to serve once the forum's law says documents must go abroad; it does not decide whether they must. Schlunk used this to defeat the Convention: service on Volkswagen's U.S. subsidiary as the parent's involuntary agent under Illinois law was completed inside the United States, so nothing went "abroad" and the Convention never engaged. That single move opens three doors that recur throughout this article:

  • Domestic agents. If the Chinese defendant has a U.S. subsidiary, a registered agent, or a statutory agent (for a foreign company registered to do business in a state), serving that domestic agent may complete service entirely within the United States--no Convention, no Central Authority, no delay.
  • Unknown address. Article 1's final sentence states the Convention "shall not apply where the address of the person to be served with the document is not known." After genuine due diligence fails to locate a defendant, the Convention does not block alternative service. Courts demand real diligence first (Compass Bank v. Katz, 287 F.R.D. 392, 394-96 (S.D. Tex. 2012); Braverman Kaskey, P.C. v. Toidze, 599 F. App'x 448, 452 (3d Cir. 2015))--but this opening is the legal foundation of Schedule A practice.
  • Contractual waiver. If the parties validly agreed, before any dispute, to substitute a private notification method for formal service, some forums treat that as eliminating the occasion to transmit abroad--the heart of Rockefeller v. SinoType, analyzed below.

Keep these three doors in mind. Much of the art of suing Chinese defendants is figuring out whether one of them is open before committing to the long Central Authority road.

China Has Slammed the Article 10 Alternatives

The Convention offers channels beyond the Central Authority. Article 10 preserves, "provided the State of destination does not object," three freedoms: (a) sending documents "by postal channels"; (b) officer-to-officer service; and (c) interested-person service. China has objected to all three subparts of Article 10. That objection is decisive, because it removes the option--available in many other treaty countries--of simply mailing the summons.

This is exactly where Water Splash, Inc. v. Menon, 137 S. Ct. 1504 (2017), both illuminates and disappoints. Water Splash confirmed that Article 10(a) does authorize service by mail where the destination state does not object and forum law permits it. Wonderful--except it does U.S. plaintiffs no good against China, which has objected. And in recent practice the Chinese Central Authority has pushed further, taking the position--reflected in communications surfacing around 2025--that email service likewise falls within "postal channels" covered by its Article 10(a) objection. The argument is contestable (email is not obviously a "postal channel," and the 1965 drafters never imagined it), but the safe planning assumption for 2026 is that China treats email to a mainland address as objected-to service. China permits narrow Article 8 consular service on U.S. nationals in China, but U.S. consular regulations (22 C.F.R. Part 92) bar consular officers from serving process for private litigants except in narrow circumstances, so that channel is effectively closed too.

The bottom line: to serve a Chinese company or individual physically present in mainland China at a known address, the Central Authority channel is, in the overwhelming majority of cases, the only method that produces service recognized by both U.S. and Chinese courts. Everything else is either a workaround that depends on the Convention not applying, or a calculated bet that you will never need to enforce inside China. For the full step-by-step of running the Central Authority package--address verification, certified translation, USM-94 assembly, the US$95 fee, the Article 6 certificate, and the realistic four-to-twelve-month timeline--see our companion guide, which treats that machinery in detail. Here, we turn to the part that is distinctively the IP litigator's: what you do while that clock runs, and the cases where you can avoid it entirely.

Rule 4(f)(3): Court-Ordered Email Service and the Split That Defines Schedule A

If the Central Authority is the slow front door, Rule 4(f)(3)--service "by other means not prohibited by international agreement, as the court orders"--is the side door IP litigators increasingly use. Understanding precisely when it is open is one of the most consequential issues in this area, and it is where U.S. courts genuinely disagree.

How the Motion Works

Under Rule 4(f)(3), a plaintiff moves the court--often ex parte--for an order authorizing a non-standard method: commonly email, but also service on U.S.-based counsel, a U.S. subsidiary, a social-media account, or by online publication on a case website. As Rio Properties established, this is not relief of last resort. It is subject to two hard limits and one soft one. The hard limits: the ordered method must (1) not be "prohibited by international agreement," and (2) comport with due process--it must be "reasonably calculated, under all the circumstances, to apprise" the defendant of the suit (Mullane; Rio, 284 F.3d at 1016). The soft limit: many courts, in their discretion, want to see that the plaintiff tried the Convention or that Convention service would be futile or unduly slow--but courts split even on that.

The whole ballgame, for China, is the first hard limit: is email service "prohibited by international agreement"?

The Split on Emailing Chinese Defendants

Two readings have emerged, and the difference turns on what the Convention "prohibits."

The permissive view. The Convention is not a comprehensive code of every permissible service method; it governs the channels it addresses. Email is not among the methods the Convention authorizes or expressly forbids. China's Article 10 objections target postal channels and officer/interested-person service, not email, which the 1965 drafters never contemplated. Because the Convention does not "prohibit" email, a court may order it under Rule 4(f)(3) so long as it satisfies due process--especially where the defendant transacts online, communicates by email, and has no reliably findable physical address. This view powers most Schedule A cases.

The restrictive view. Because China is a signatory that has objected to Article 10(a) postal service, and because (on this reading) email is a postal channel or is at least within the spirit of that objection, ordering email service would authorize a method "prohibited by international agreement"--the very thing Rule 4(f)(3) forbids. On this view, when a defendant's mainland address is known and the Convention applies, email service is off the table. China's 2025 Central Authority position--that email is "postal channels"--gives this view fresh ammunition.

The split is not academic. A wave of trademark cases in the counterfeiting-heavy Northern District of Illinois has wrestled with this exact question, and the results turn on whether the defendant's address was "known" (triggering Convention exclusivity under Article 1) or genuinely unknown (taking the case outside the Convention entirely). Luxottica Group S.p.A. v. Partnerships & Unincorporated Associations Identified on Schedule "A," 391 F. Supp. 3d 816 (N.D. Ill. 2019), is the canonical discussion: the court authorized electronic service on online sellers precisely because their identities and addresses were concealed, placing the case outside the Convention. The practical upshot for 2026 sorts cleanly into two boxes:

  • If the Chinese defendant's address is unknown after genuine due diligence, Article 1 takes the case outside the Convention, and email service under Rule 4(f)(3) stands on firm footing. This is the anchor of Schedule A practice.
  • If the address is known, the Convention applies, China has objected to Article 10, and email service becomes legally fragile. A judgment built on it is exposed to a Rule 60(b)(4) attack at home and almost certainly unenforceable in China.

The enforcement asterisk. Even where a U.S. court permits email service, that does nothing to make the resulting judgment enforceable inside China, where courts measure service against China's own rules and the Convention. Rule 4(f)(3) email service is therefore best understood as a tool for cases where you do not need to enforce in China--where the defendant's reachable assets are U.S. marketplace funds, U.S. bank accounts, or third-country property.

Two Worked Hypotheticals (Both Fictional)

Suppose Trailhead Outdoors, Inc., a U.S. brand, discovers that fifty anonymous storefronts on a marketplace--names like "BestGear2025" and "SunnyMallShop," with no findable corporate identity and no physical address, but all routing communications and payments through China--are selling counterfeit Trailhead jackets. Trailhead files a single trademark suit naming the storefronts as Doe defendants on a sealed "Schedule A," conducts diligence that surfaces no registered address, and moves under Rule 4(f)(3) for an order authorizing service by email to the storefront contact addresses and by posting on a case website. Because the addresses are genuinely unknown, the court finds the Convention inapplicable under Article 1, authorizes electronic service as due-process-adequate (these defendants plainly operate by email), and enters a TRO freezing the storefronts' marketplace-held funds. Trailhead never touches the Central Authority. This is the paradigmatic, defensible use of Rule 4(f)(3).

Contrast Cascade Semiconductor, LLC, which knows exactly which Shenzhen corporation infringes its patent, has the registered address, and wants a damages judgment enforceable against the company's Chinese assets. For Cascade, an email shortcut is a trap: the address is known, the Convention applies, China has objected, and any Chinese enforcement court will reject a judgment built on emailed papers. Cascade's correct path is the slow, certain Central Authority road--begun early, with parallel injunctive and customs measures running alongside.

The two hypotheticals are mirror images, and the mirror is the address-known question. Get that wrong and everything downstream--the freeze, the default, the enforcement--rests on sand.

The Schedule A Playbook: Suing Faceless Chinese Counterfeiters

No discussion of suing Chinese IP defendants in 2026 is complete without the Schedule A case, the procedural innovation--pioneered in the Northern District of Illinois and now common nationwide--that has reshaped brand enforcement against anonymous online sellers. It is worth understanding as an integrated machine, because each part depends on the others.

The model in motion. A rights holder identifies dozens or hundreds of e-commerce storefronts selling counterfeits or infringing goods. It sues them together as Doe defendants listed on a sealed Schedule A (sealed so the defendants cannot tip each other off and scatter). It moves, ex parte, for a temporary restraining order that (1) freezes the storefronts' marketplace- and payment-platform-held funds, (2) requires the platforms to disable the listings, and (3) authorizes expedited discovery to identify the sellers and their financial accounts. It then serves the defendants by court-ordered email and online publication under Rule 4(f)(3). When the sellers default--as most do--the plaintiff converts the frozen funds into a judgment.

This model lives or dies on two doctrines we have already met. First, Article 1's "address unknown" carve-out: because these sellers conceal their identities and locations, plaintiffs argue (and many courts accept) that the Convention does not apply, freeing electronic service. Second, due process under Mullane: because the sellers demonstrably operate by email and marketplace messaging, electronic notice is "reasonably calculated" to reach them. Luxottica, 391 F. Supp. 3d 816, ties the two together.

Why does the asset freeze come first, before the defendant is ever heard? Because notice would be self-defeating. A counterfeiter who learns of suit empties its Alipay balance and platform wallet within hours and dissolves the storefront. The freeze is therefore sought ex parte under the Rule 65 machinery discussed next, on the theory that the very nature of the defendant--anonymous, offshore, liquid, and evasive--supplies the "immediate and irreparable injury before the adverse party can be heard" that Rule 65(b)(1) requires. The asset freeze typically reaches not only the marketplace's held balances but also funds in PayPal, Alipay, and other payment processors served with the order, on the Mareva-adjacent theory that a court with personal jurisdiction may freeze a defendant's assets to preserve an eventual equitable accounting of infringing profits.

The controversy, and the guardrails. Schedule A practice is powerful and contested. Critics flag joinder strain--are hundreds of unrelated sellers properly joined under Rule 20 merely because they all sell counterfeits of the same mark? They flag due-process concerns about freezing a seller's entire account, including non-infringing inventory, before any hearing. And they flag the risk of sweeping in legitimate sellers caught by overbroad keyword matching. Courts have responded by tightening the screws: demanding genuine, documented due diligence into each defendant's identity and address before accepting that the Convention does not apply; scrutinizing joinder; and, in some districts, limiting freezes to amounts traceable to the infringing sales rather than the seller's entire balance. Used honestly, Schedule A is the most effective tool in the brand-enforcement arsenal against faceless Chinese counterfeiters. Used carelessly--with boilerplate diligence and a freeze that overreaches--it produces judgments as fragile as any other improperly served paper, and increasingly draws judicial skepticism. For the broader online-enforcement context, see Brand Protection Online: A Strategic Guide for Businesses.

The Ex Parte Engine: Rule 65 TROs and Asset Freezes

The Schedule A freeze, the patent TRO, and the trade-secret seizure all run on the same statutory engine: Federal Rule of Civil Procedure 65. Because the entire point against a Chinese defendant is often to act before the defendant can react, the ex parte provisions of Rule 65 are where the IP litigator does some of the most important work in the case. They are also unforgiving--a sloppy ex parte application is the surest way to have your freeze dissolved and your client exposed to a wrongful-restraint claim.

What It Takes to Get a TRO Without Notice

Rule 65 offers two instruments. A preliminary injunction preserves the status quo pending the merits, but it "may issue only on notice to the adverse party" (Rule 65(a)(1)) and typically requires a hearing. A temporary restraining order is the short-fuse bridge to that hearing, and--crucially--it can issue without notice. But Rule 65(b)(1) permits an ex parte TRO only if two conditions are met:

  • (b)(1)(A): specific facts in an affidavit or verified complaint clearly show that immediate and irreparable injury, loss, or damage will result to the movant before the adverse party can be heard in opposition; and
  • (b)(1)(B): the movant's attorney certifies in writing (i) any efforts made to give notice and (ii) the reasons why notice should not be required.

That second certification is the heart of the matter in a China case, and it is where the unique facts of cross-border IP enforcement become your friend. The "reasons why notice should not be required" are not generic. They are concrete: the defendant is an anonymous offshore seller whose assets are liquid platform balances that can be wired to China in minutes; the defendant has previously evaded enforcement by reincarnating storefronts; Hague service would take months, during which the assets would vanish. Document those facts specifically. Courts reward a precise evasion narrative and punish boilerplate distrust.

An ex parte TRO carries strict limits under Rule 65(b)(2). It expires within 14 days unless the court extends it for good cause (by up to 14 more days) or the parties consent to an extension. The order must state the date and hour it issued, describe the irreparable injury, and explain why it issued without notice. And under Rule 65(b)(3), once an ex parte TRO is in place, the preliminary-injunction hearing must be set "at the earliest possible time," taking precedence over all other matters except older ex parte TROs. The practical rhythm of a Schedule A case follows this clock exactly: file under seal, get the ex parte TRO and freeze, serve by email and publication during the 14 days, convert the TRO to a preliminary injunction at the hearing (now that the sellers have notice and mostly do not show), and proceed toward default.

The Bond, and the Asymmetry You Must Counsel Your Client About

Rule 65(c) requires the movant to post security--usually a bond--"in an amount that the court considers proper to pay the costs and damages sustained by any party found to have been wrongfully enjoined or restrained." The amount is the court's call (Sanofi-Synthelabo v. Apotex, Inc., 470 F.3d 1368, 1385 (Fed. Cir. 2006)), and it should track the harm the defendant would suffer from an erroneous restraint. Here is the silver lining for plaintiffs, and a critical client-counseling point: if the restraint turns out to be wrongful, the defendant's recovery is generally capped at the bond amount (Front Range Equine Rescue v. Vilsack, 844 F.3d 1230, 1234 (10th Cir. 2017); Int'l Ass'n of Machinists & Aerospace Workers v. E. Airlines, Inc., 925 F.2d 6, 10 (1st Cir. 1991)). That cap is a feature of Rule 65 relief--and, as we will see, it is precisely the protection the Defend Trade Secrets Act takes away for its seizure remedy.

Drafting the Order So It Survives

Rule 65(d) governs the content of every TRO and preliminary injunction, and it is exacting. The order must (A) state the reasons it issued, (B) state its terms specifically, and (C) describe in reasonable detail--without referring to the complaint or any other document--the acts restrained or required. That last point trips up litigators who draft a freeze order that says "enjoined from the conduct described in the complaint." An order so vague is unenforceable and invites reversal. Spell out, on the face of the order, the accounts frozen, the platforms bound, the listings to be disabled, and the conduct prohibited. For the contours of injunctive relief in patent cases specifically, including the proposed-order mechanics, the Practical Law materials on order-to-show-cause practice and patent preliminary-injunction considerations are the standard desk references.

The Patent Preliminary Injunction Against a Chinese Manufacturer

When the Chinese defendant is a known manufacturer whose infringing product is flooding the U.S. market, the most valuable interim remedy is often a preliminary injunction under 35 U.S.C. § 283--an order stopping the sales while service grinds through Beijing. It is an extraordinary remedy, "not to be routinely granted" (High Tech Med. Instrumentation, Inc. v. New Image Indus., Inc., 49 F.3d 1551, 1554 (Fed. Cir. 1995)), and the patentee must carry all four classic factors as articulated in Winter v. NRDC, 555 U.S. 7 (2008), and applied in patent cases by the Federal Circuit (Luminara Worldwide, LLC v. Liown Elecs. Co., 814 F.3d 1343, 1352 (Fed. Cir. 2016)):

  1. Likelihood of success on the merits--likely infringement of at least one asserted claim, and that the claim will withstand validity challenges (AstraZeneca LP v. Apotex, Inc., 633 F.3d 1042, 1050 (Fed. Cir. 2010)). Bare pleadings and attorney argument do not suffice; the patentee needs actual evidence and a claim construction (Oakley, Inc. v. Sunglass Hut Int'l, 316 F.3d 1331, 1339 (Fed. Cir. 2003)). On validity, the accused infringer need only raise a "substantial question," whereupon the burden shifts to the patentee to show that the defense "lacks substantial merit" (Altana Pharma AG v. Teva Pharms. USA, Inc., 566 F.3d 999, 1005-06 (Fed. Cir. 2009)).
  2. Irreparable harm--and here the China context bites. After eBay Inc. v. MercExchange, LLC, 547 U.S. 388 (2006), there is no presumption of irreparable harm even from a strong merits showing (Robert Bosch LLC v. Pylon Mfg. Corp., 659 F.3d 1142, 1149 (Fed. Cir. 2011)). The patentee must prove it--price erosion, lost market share, eroded goodwill--and must establish a causal nexus between the infringement and the harm (Apple Inc. v. Samsung Elecs. Co., 695 F.3d 1370, 1374-75 (Fed. Cir. 2012)). One species of irreparable harm is tailor-made for the Chinese-defendant case: the likely unrecoverability of a money judgment because the infringer's assets sit beyond the practical reach of U.S. collection (Robert Bosch, 659 F.3d at 1154-56). A patentee who can show that a damages award against a Shenzhen manufacturer would be uncollectable has a powerful irreparable-harm argument that the cap-and-trade of money damages cannot make it whole.
  3. Balance of hardships, weighing the harm to the patentee against the harm to the infringer (Acumed LLC v. Stryker Corp., 551 F.3d 1323, 1330 (Fed. Cir. 2008)); intentional copying, common in counterfeiting, tilts this factor toward the patentee.
  4. Public interest, which generally favors enforcing valid patents (Abbott Labs. v. Andrx Pharms., Inc., 452 F.3d 1331, 1348 (Fed. Cir. 2006)).

Two cautions. First, delay kills irreparable harm. A patentee who sits on its rights for a year after learning of infringement will struggle to convince a court the harm is urgent (Apple, Inc. v. Samsung Elecs. Co., 678 F.3d 1314, 1325-26 (Fed. Cir. 2012)). The Hague-service delay is largely outside your control; your own delay in moving is not, so file promptly once you know the facts. Second, if the patent is a standard-essential patent subject to a FRAND commitment, the irreparable-harm showing is much harder, because the patentee has effectively agreed to accept a royalty (Apple Inc. v. Motorola, Inc., 757 F.3d 1286, 1331-32 (Fed. Cir. 2014)). On the SEP/FRAND landscape generally, see Standard-Essential Patents and FRAND Licensing in 5G and IoT. For the substantive infringement standard underlying the merits factor, see What Constitutes Patent Infringement.

Anti-Suit Injunctions: When the Chinese Court Strikes First

A wrinkle unique to high-stakes patent wars--especially SEP disputes--deserves its own mention, because it inverts the usual posture. In several recent global SEP battles, a defendant has raced to a Chinese court and obtained an anti-suit injunction purporting to bar the patentee from litigating or enforcing its rights in U.S. courts, on pain of substantial daily fines. The U.S. response is an anti-interference (or anti-anti-suit) injunction. In Ericsson Inc. v. Samsung Electronics Co., 2021 WL 89980 (E.D. Tex. Jan. 11, 2021), the Eastern District of Texas granted exactly that--an injunction designed to counteract a Chinese court's anti-suit order and preserve Ericsson's ability to litigate its SEP claims in the United States. Notably, these injunctions are governed by regional-circuit law, not Federal Circuit law, and apply a test distinct from the four-factor patent PI standard. For the patentee fighting a Chinese manufacturer that has weaponized the Chinese courts, the anti-interference injunction is an essential counter-move--and one more reason that, in cross-border patent litigation, the procedural battlefield can matter as much as the merits.

When the IP at stake is a trade secret and the fear is that a defendant will spirit the misappropriated data offshore--say, to servers in China--the Defend Trade Secrets Act of 2016 offers a remedy with no analog in ordinary civil practice: an ex parte civil seizure under 18 U.S.C. § 1836(b)(2). On the plaintiff's application, a court can order federal law enforcement to seize the computers, phones, drives, and cloud-account credentials containing the plaintiff's trade secrets--before the defendant knows a suit exists. It is, fairly described, the nuclear option, and the statute surrounds it with guardrails precisely because of its extraordinary nature.

The court may grant seizure only on findings of eight elements under § 1836(b)(2)(A)(ii). Two of them map almost perfectly onto the Chinese-defendant risk profile, which is why the remedy is so attractive in cross-border trade-secret cases: (1) that an ordinary Rule 65 injunction or TRO would be inadequate because the party would evade, avoid, or otherwise violate it, and (7) that the target, if given advance notice, would destroy, move, hide, or otherwise make inaccessible the trade-secret materials. A defendant with the means and motive to exfiltrate data to China and put it beyond U.S. court reach is the paradigm Congress had in mind. The remaining elements require immediate and irreparable injury, a favorable balance of harms (including harm to third parties), likelihood of success on the merits, the target's actual possession of the trade secret and the property, a description of the matter to be seized with reasonable particularity, and--critically--that the applicant has not publicized the requested seizure.

That last element sets a trap the unwary spring routinely: do not send a cease-and-desist letter before applying. Courts have treated a pre-suit C&D as "publicizing" the seizure and as proof that ordinary process would have sufficed, defeating the application (see Int'l Auto. Technicians' Network Inc. v. Winzig, No. 18-cv-4208 (C.D. Cal. May 21, 2018)). The surprise is the remedy; tip your hand and you lose it. Courts also require concrete evidence of prior deceit to satisfy the evasion element--lying, concealment, false identities, deletion of data--not mere suspicion (see, e.g., Solar Connect, LLC v. Endicott, 2018 WL 2386066 (D. Utah Apr. 6, 2018)). And if the defendant offers to surrender devices voluntarily for forensic inspection, the "exceptional circumstances" justifying seizure evaporate (Hayes Healthcare Servs., LLC v. Meacham, 2019 WL 2637053 (S.D. Fla. Feb. 1, 2019)).

The procedure is unusual and demanding. The seizure is executed by law enforcement, and the plaintiff is barred from any involvement in the physical seizure (§ 1836(b)(2)(E)); the order must provide for the narrowest seizure necessary (§ 1836(b)(2)(B)(ii)); seized property goes into the court's custody (§ 1836(b)(2)(D)); and an initial hearing must occur within seven days (§ 1836(b)(2)(B)(v)). The court may appoint a special master and a neutral technical expert to identify the trade secrets and return everything else.

Now the asymmetry promised earlier. Under Rule 65(c), a wrongfully restrained defendant's recovery is capped at the bond. The DTSA deliberately removes that cap: § 1836(b)(2)(G) creates a private right of action for wrongful or excessive seizure with damages not limited to the security posted, including lost profits, cost of materials, loss of goodwill, and even punitive damages and attorney's fees for bad-faith seizures. The lesson for counsel is blunt: the DTSA seizure is a remedy of last resort, justified only when the evidence of evasion and offshore-flight risk is overwhelming. Where it fits--a departing engineer caught copying source code to a personal cloud account synced to a server in Shenzhen, with a demonstrated history of concealment--it is unmatched. Where it is merely convenient, it is a sanctions risk wearing a statute.

Parallel Tracks: What to Run While the Central Authority Sleeps

A patient IP plaintiff is rarely a passive one. The interim remedies above are court-ordered; several powerful tools require no court order, and no service, at all. The litigation track and the administrative track should run in parallel from day one, because in IP the harm compounds while the clock runs--patent infringers keep manufacturing, online piracy replicates at zero marginal cost, counterfeits saturate the market, and a trade secret, once disseminated, may be impossible to recall.

  • DMCA takedown notices under 17 U.S.C. § 512 to U.S.-based hosts and platforms remove infringing content without serving the infringer at all. See How to File a DMCA Takedown Notice and Respond to One.
  • Platform enforcement programs--Amazon Brand Registry, Alibaba's IPP/AliProtect, Temu, and eBay's VeRO--strip infringing listings administratively, often within days.
  • U.S. Customs recordation. Recording registered trademarks and copyrights with Customs and Border Protection enables border seizure of infringing imports, cutting off the goods before they reach U.S. consumers regardless of where the seller hides.
  • ITC Section 337 investigations (19 U.S.C. § 1337) can yield exclusion orders barring infringing imports at the border--an enforcement mechanism that does not depend on a money judgment enforceable in China.

A point worth emphasizing for online cases: because the harm accelerates while Hague service crawls, these parallel measures are not a backstop but the front line. The TRO-driven asset freeze captures the seller's U.S.-side money before it can be repatriated; the takedowns and customs recordation choke off the infringing supply; the litigation, even if it ends in an uncollectable default judgment, supplies the legal predicate for the freeze and the discovery that unmasks the seller. For the strategic integration of these levers, see Brand Protection Online.

Locking Down the Evidence Before It Vanishes

IP cases against Chinese defendants live on digital evidence--product listings, marketing copy, communications--often hosted in China. Two sobering realities frame collection. First, the companion treaty, the Hague Evidence Convention, works poorly with China: requests routed through it are notoriously slow and frequently never executed. Second, China's data and state-secrecy laws (the Data Security Law, the Personal Information Protection Law, and rules restricting cross-border transfer of evidence for foreign proceedings) can affirmatively bar a Chinese party from producing materials abroad without government approval. The practical answer is to capture public-facing evidence early and independently--forensic web preservation and properly authenticated screenshots of infringing listings before the defendant can scrub them. For the methodology and admissibility framework, see Capturing the Web: A Practitioner's Guide to Authenticating Website Screenshots as Evidence in Federal Court, and on the legal boundaries of automated collection, Data Scraping After hiQ v. LinkedIn.

The Rockefeller Workaround: Contracting Around Hague Service

For parties sophisticated enough to plan before a dispute, the most elegant escape from the service problem is to contract around it--and the leading authority is the California Supreme Court's unanimous 2020 decision in Rockefeller Technology Investments (Asia) VII v. Changzhou SinoType Technology Co., 9 Cal. 5th 125, 460 P.3d 764 (2020), cert. denied, 141 S. Ct. 374 (2020).

The facts deserve their reputation. In 2008, Rockefeller (a U.S. investment fund) and Changzhou SinoType (a Chinese company) signed a memorandum of understanding agreeing to give each other notice "via Federal Express or similar courier, with copies via facsimile or email," to submit to California jurisdiction, and to consent to "service of process in accord with the notice provisions above." When the deal collapsed, Rockefeller demanded JAMS arbitration, serving by FedEx and email exactly as the MOU specified. SinoType's chairman received the notices but did not participate. The arbitrator entered a default award of $414,601,200, which a California court confirmed. Then SinoType surfaced and moved to vacate, arguing that FedEx service was "postal channels" service barred by China's Article 10 objection.

The California Supreme Court rejected the argument, reasoning straight through Schlunk: the Convention attaches only when the forum's law requires formal service of process to be transmitted abroad. Under California law, contracting parties may consent to jurisdiction and waive formal service in favor of an agreed private method. Having done so, the parties created no occasion to transmit documents abroad for service--so the Convention never engaged, and its Article 10 objections were irrelevant. The court warned that a contrary rule "would sow confusion and encourage gamesmanship," such as a party fleeing the country to dodge an obligation it knowingly assumed.

Rockefeller hands proactive IP counsel a genuine tool, but a sharp-edged one. The opportunity: when negotiating any agreement with a Chinese counterparty--a software license, a patent license, a manufacturing or supply contract, a distribution deal, an NDA--include clauses that (1) submit both parties to a specified U.S. court, (2) waive formal service in favor of a defined private method (e.g., FedEx to a stated address with email copies, deemed received after a set number of business days), and (3) consent to service by that method. The limits: Rockefeller is a California decision; other forums are not bound by it, so research your forum's law on contractual waiver before relying on the clause. And more important, a U.S. judgment obtained through waived service may be unenforceable in China, because the 2024 Civil Procedure Law lists improper service as a ground to refuse recognition. Rockefeller gives you a valid U.S. judgment; whether it has teeth depends on whether the defendant holds assets outside China you can reach.

Two drafting refinements separate clauses that hold up from clauses that crumble. First, negotiate the waiver, don't bury it--a record of knowing, arm's-length assent (separate initialing, bargaining history, explicit recitals) is what survives a later challenge. Rockefeller worked partly because the court could point to specific negotiated language. Second, add a fallback: provide that if the contractual mechanism is held unenforceable, the parties consent to formal Hague Central Authority service. That belt-and-suspenders clause gives even a skeptical forum a clean formal path. For where these provisions live, see Drafting Enforceable Non-Disclosure Agreements for Technology Transactions and Popular Legal Documents for Startups.

The Arbitration Upgrade

Notice that Rockefeller itself was an arbitration award--and that is not incidental. Foreign arbitral awards are enforceable in China under the New York Convention, to which both the U.S. and China belong, and Chinese courts have historically been far more willing to enforce foreign arbitral awards than foreign court judgments. A well-drafted arbitration clause with a clear private-notice mechanism therefore delivers both procedural speed and a more reliable enforcement pathway. Hong Kong deserves special mention: as a common-law SAR it operates the Convention faster than the mainland, and a 2019 arrangement allows mainland courts to grant interim measures (including asset freezes) in aid of HKIAC-seated arbitrations. An arbitration clause seated in Hong Kong under HKIAC rules can combine efficiency with a credible enforcement path into the mainland.

Default Judgments When the Defendant Vanishes (Convention Article 15)

A recurring scenario: you complete Central Authority service (or believe you have), the Chinese defendant ignores the suit, and you want a default judgment--but the Article 6 certificate is slow, incomplete, or never arrives. The Convention anticipates this in Article 15.

Article 15's first paragraph instructs that, where a defendant served abroad has not appeared, judgment "shall not be given" until it is established that service was effected by a Convention-recognized method and in sufficient time to defend. U.S. courts applying Article 15 have generally found that allowing roughly a month between completed service and the default application satisfies the "sufficient time to defend" requirement (Marcus Food Co. v. DiPanfilo, 2010 WL 3946314, at *6 (D. Kan. 2010)). Article 15's second paragraph--and the United States made the declaration that activates it--permits a court to enter judgment without a returned certificate if three conditions are met: (a) the document was transmitted by a Convention-approved method; (b) at least six months (a period the judge deems adequate) have elapsed; and (c) no certificate has been received despite every reasonable effort to obtain one. Courts require more than a single follow-up to show "every reasonable effort" (Universal Trading & Investment Co. v. Kiritchenko, 2007 WL 660083, at *4 (N.D. Cal. 2007)).

So calendar the six-month mark from the date you transmitted the request. If service appears to have occurred but no certificate has come back, and you have genuinely pressed the Central Authority, Article 15(2) may let you proceed to default. Use it carefully and document your efforts, because a default judgment is exactly the kind of judgment a defendant will later try to unwind for defective service under Rule 60(b)(4)--and Article 16 gives a non-appearing defendant a further window (in the U.S. declaration, the later of the court's deadline or one year from judgment) to seek relief if, without fault, it lacked timely knowledge and has a prima facie defense.

China's 2024 Civil Procedure Law: The Enforcement Endgame

China's revised Civil Procedure Law took effect on January 1, 2024, and it matters for one reason above all: it shapes whether the judgment you fight for years to win can be enforced where the defendant's assets actually sit.

On the encouraging side, the revised CPL articulates a clearer framework for recognizing foreign judgments based on treaty or reciprocity. China's Supreme People's Court has moved in recent years from a restrictive "de facto reciprocity" posture--enforce another country's judgments only if it has already enforced a Chinese one--toward a more workable "presumed" or "legal" reciprocity, reflected in the 2021-2022 national court conference summaries and the 2024 amendments. There have been isolated instances of Chinese courts recognizing U.S. monetary judgments under reciprocity, a meaningful if still nascent shift.

On the cautionary side, the 2024 CPL enumerates grounds for non-recognition, and improper service sits prominently among them: a Chinese court may refuse recognition where the defendant was not lawfully summoned or was denied a reasonable opportunity to defend, measured against Chinese law and China's treaty obligations--including the Hague Service Convention. The reciprocity door has opened a crack; the service requirement remains the deadbolt.

Two conclusions follow. First, the reciprocity reforms are still being tested case by case, and the volume of successful U.S.-judgment recognitions remains small; do not assume your judgment will be enforced in China merely because the doctrinal door is ajar. Second--and non-negotiable--the pathway to enforcement, if it exists, runs through proper service. A judgment obtained without Hague-compliant service is almost certainly unenforceable in China regardless of how meritorious the underlying IP claim. Every shortcut taken at the service phase is a vulnerability the defendant's Chinese counsel will exploit at the recognition phase. Treat Hague compliance not as a procedural nicety but as a substantive precondition to your client's rights having value where it counts.

This is the deeper reason the entire field forks around one question, asked at the very beginning of the case: where are the assets? If the defendant's reachable money is in U.S. marketplace balances, U.S. bank accounts, or third-country property, you can lean on Rule 4(f)(3), Schedule A, and Rockefeller-style shortcuts, take a fast U.S. judgment, and never worry about Chinese enforcement. If the only assets worth collecting are inside China, every shortcut becomes a liability, and the slow, certain Central Authority road--plus, ideally, an arbitration clause for next time--is the only road that ends in payment. The territoriality of IP rights makes this fork inescapable: a U.S. patent grants rights only in the United States (35 U.S.C. § 271), yet the infringement, the defendant, and the assets may all sit in China. Build the case around the answer to the assets question, and build it from day one.

A Practical Sequence: From Discovery of Infringement to Enforceable Relief

Rather than a generic checklist, here is the decision sequence a seasoned cross-border IP litigator actually runs.

At intake, answer two questions before anything else. First, where are the collectable assets?--U.S./third-country, or China? This decides whether strict Hague compliance is essential or optional. Second, is the defendant identifiable, with a known registered address?--or anonymous? This decides whether you are running a Central Authority case or a Schedule A case. Then review every contract with the defendant for a Rockefeller-style service waiver or arbitration clause that might let you skip the Convention entirely.

If the defendant is anonymous (the counterfeiter case): document genuine due diligence into each defendant's identity and address (this is what takes the case outside the Convention under Article 1), file under seal, and move ex parte under Rule 65(b)(1) for a TRO that freezes platform and payment-processor balances and authorizes expedited discovery. Build the "why no notice" certification on specific evasion and flight facts. Serve by court-ordered email and online publication under Rule 4(f)(3). Convert to a preliminary injunction at the Rule 65(a) hearing, then proceed to default and turn the frozen funds into a judgment. Run platform takedowns and customs recordation in parallel.

If the defendant is a known manufacturer and you need to enforce in China: start Central Authority service immediately--it is the long pole in the tent. While it runs, seek a preliminary injunction (or, in a clear trade-secret case with overwhelming evasion evidence, a DTSA seizure), file DMCA takedowns, record with Customs, and consider an ITC Section 337 action. Calendar the six-month Article 15(2) mark in case the certificate never returns. Preserve public-facing evidence forensically before it disappears.

If a valid contractual waiver or arbitration clause exists and assets are reachable outside China: evaluate the Rockefeller route or arbitration (ideally HKIAC/Hong Kong) to bypass the Convention and secure a New York Convention enforcement path.

In every case: model enforceability under the 2024 CPL before you invest in a money judgment, and never send a cease-and-desist before an intended ex parte DTSA seizure.

Proactive Drafting: The First and Best Line of Defense

The most effective response to the Hague problem is to defuse it before a dispute exists. When negotiating any agreement with a Chinese counterparty, draft the dispute-resolution provisions with the same care as the commercial terms, addressing three elements: a clear submission to jurisdiction (to a named U.S. court, or to a named arbitral institution with a specified seat--Hong Kong/HKIAC is often the sweet spot); a waiver of formal service in favor of a defined private notification method with deemed-receipt timing; and a binding arbitration agreement supplying a New York Convention enforcement pathway more reliable in China than court-judgment enforcement. Negotiate the waiver visibly, and add a fallback to formal Hague service in case a forum balks. A well-built dispute-resolution clause can save years of delay and six figures in enforcement costs--and it is the rare IP-protection measure that costs almost nothing to install.

Key Takeaways

  • Service is strategy, not paperwork. Against Chinese defendants, the service decision may be the most consequential one in the case, because improper service can void an otherwise winning judgment at home and render it unenforceable in China.
  • The fork is the asset question. If collectable assets sit outside China, lean on Rule 4(f)(3), Schedule A, and Rockefeller shortcuts. If they sit inside China, the Central Authority road is the only one that ends in payment.
  • Schedule A is the counterfeiter-killer--when run honestly. It works because anonymous sellers' addresses are unknown (Article 1 takes the case outside the Convention) and they operate by email (so electronic notice satisfies Mullane). Boilerplate diligence and overbroad freezes are how it fails.
  • Master the ex parte engine. Rule 65(b)(1)'s specific-facts and no-notice certification, the 14-day TRO clock, the 65(c) bond cap, and the DTSA's uncapped wrongful-seizure exposure are the difference between a freeze that holds and a sanctions exposure.
  • Patent PIs turn on irreparable harm. Post-eBay there is no presumption; the uncollectability of a judgment against a Chinese manufacturer is a potent irreparable-harm argument, and anti-interference injunctions counter Chinese-court anti-suit orders.
  • Plan ahead with arbitration and waiver clauses. Proactive drafting--especially HKIAC/Hong Kong arbitration--can sidestep the Hague apparatus and deliver a New York Convention enforcement path Chinese courts respect.

Frequently Asked Questions

Can I just mail or email the summons and complaint to a Chinese company? Not safely, if its mainland address is known. China has objected to all of Article 10 of the Hague Service Convention, so postal-channel service is not permitted, and the Chinese Central Authority now takes the position that email counts as a "postal channel" covered by that objection. Water Splash v. Menon (2017) confirms mail service is allowed under the Convention only where the destination state does not object--and China does. For a known mainland address, use the Central Authority. Email becomes viable mainly when the address is genuinely unknown (the Schedule A scenario).

What is a "Schedule A" case and why does it involve Chinese defendants? It is a procedural model--pioneered in the Northern District of Illinois and now nationwide--in which a brand sues many anonymous online storefronts together as Doe defendants on a sealed "Schedule A," freezes their marketplace and payment-platform funds by ex parte TRO, and serves them by court-ordered email and online publication under Rule 4(f)(3). It works because the sellers' true addresses are unknown (so the Convention does not apply under Article 1) and they demonstrably operate by email (so electronic notice satisfies due process). Most such sellers are based in China.

How do I freeze a Chinese counterfeiter's money before it disappears? Through an ex parte temporary restraining order under Federal Rule of Civil Procedure 65(b)(1), supported by specific facts in an affidavit showing immediate, irreparable harm before the defendant can be heard, plus your attorney's written certification of why notice should not be required. The order can reach marketplace-held balances and funds at payment processors (PayPal, Alipay) served with it. The TRO lasts 14 days (extendable once for good cause), and you must post a bond under Rule 65(c)--but a wrongfully restrained defendant's recovery is generally capped at that bond.

When can I get a DTSA ex parte seizure against a defendant who might send my trade secrets to China? Only on the eight findings in 18 U.S.C. § 1836(b)(2)(A)(ii)--most importantly, that an ordinary injunction would be inadequate because the defendant would evade it, and that the defendant would destroy or move the materials if given advance notice. The offshore-flight risk fits that profile, but you need concrete evidence of prior deceit, not mere suspicion. Do not send a cease-and-desist first--it can defeat the "not publicized" element. And note that wrongful-seizure damages are not capped at your bond, so reserve this remedy for the strongest cases.

Can I get a preliminary injunction against a Chinese manufacturer while Hague service is still pending? Yes. Courts can enter a TRO ex parte and a preliminary injunction after a hearing before foreign service is complete, on the four-factor Winter showing. For patents, remember there is no presumption of irreparable harm after eBay--but the likely uncollectability of a money judgment against a Chinese defendant is itself a strong irreparable-harm argument. Move promptly, because your own delay (unlike the Hague delay) undermines the urgency.

If I win a U.S. judgment, can I enforce it against the defendant's assets in China? Maybe, but cautiously. China's 2024 Civil Procedure Law recognizes foreign judgments based on treaty or reciprocity, and there have been a handful of U.S.-judgment recognitions under an evolving reciprocity doctrine--but the track record is thin, and improper service is an express ground for refusing recognition. A judgment built on anything short of Hague-compliant service is very unlikely to be enforced in China. Foreign arbitral awards, by contrast, are enforced far more reliably under the New York Convention.
