Moving for a Preliminary Injunction in a Trademark Case: A Checklist

By Casey Scott McKay · 2026-06-28

A preliminary injunction is the remedy most trademark plaintiffs actually want: a fast court order that stops the infringement now, while the lawsuit grinds on. This checklist walks you phase by phase through earning one, from the strategic decision to move, through confirming standing and venue, building the evidentiary record, and proving the four Winter factors, to the temporary restraining order track, the proposed order, the Rule 65(c) bond, expedited discovery, the hearing, and what to do after the ruling. Each item carries a plain-English Why note, frequent Trap warnings, and the controlling statute, rule, or case. A running worked example - Meridian Cyclewear versus a copycat - shows the moves in action. It closes with a Common Mistakes list and a deep set of Related Resources from the Rightsy library. Written for brand owners, in-house teams, and the litigators who carry the motion.

What This Checklist Is For

In most trademark disputes the money is a sideshow. What the brand owner actually wants is for the other side to stop - stop selling the lookalike, stop running the ads, stop showing up next to it in the same marketplace search results - and to stop now, not three years from now after a trial. The legal instrument that delivers "now" is the preliminary injunction: a court order, entered near the front of a lawsuit, freezing the infringing conduct while the case is litigated. Its emergency cousin, the temporary restraining order (TRO), buys you a few days of breathing room when even a preliminary-injunction hearing is too slow.

This checklist is the working playbook for getting one. It assumes you have already concluded, or strongly suspect, that someone is infringing your mark, and it takes you from that suspicion all the way to a signed order and its enforcement. It is organized into ten phases, each a set of concrete, checkbox-style steps. Every step carries a short Why explaining what the step accomplishes, a Trap flagging the mistake that sinks real motions, and the controlling Authority - the statute, rule, or case that governs - so you can verify rather than take our word.

For the doctrine underneath the procedure, this checklist sits directly on top of three Rightsy guides you should keep open in another tab: Stopping the Infringer: Trademark Injunctions After eBay (the four-factor standard and the irreparable-harm presumption), Likelihood of Confusion: A Brand Owner's Field Map (the merits you must show you are likely to win), and When You Win: Remedies and Damages for Trademark Infringement (where the injunction fits in the full remedial picture). A dedicated companion piece on the four-factor preliminary-injunction test drills further into the standard itself.

Who Should Use It

• Brand owners and in-house counsel deciding whether an emergency motion is worth the cost and risk, and what their lawyers will need from them.
• Litigators drafting and arguing the motion, who want a phase-by-phase map and a trap list.
• Defendants and their counsel, who will find the plaintiff's playbook reversed - every box you must check is a box your opponent will try to knock out, and the Traps below double as your openings.

What You'll Need Before You Start

• [ ] Your registration certificate(s) (or proof of common-law rights and priority of use).
• [ ] A clean record of your chain of title - proof you actually own the mark today.
• [ ] Evidence of use, sales, advertising, and reputation that shows the mark is live and valuable.
• [ ] A documented timeline: the date you discovered the infringement and every step you took afterward.
• [ ] Whatever confusion evidence exists - misdirected emails, reviews, social posts, customer calls.
• [ ] Witnesses willing to sign declarations under penalty of perjury (employees, customers, an expert).
• [ ] A realistic sense of your budget and bond capacity, because early relief is not free.
• [ ] Trademark counsel, or Rightsy's virtual trademark attorneys, to carry the motion.

How to Read the Running Example

Throughout, we follow a single invented dispute. Meridian Cyclewear, Inc. holds an incontestable federal registration for MERIDIAN for cycling jerseys, bib shorts, and gear, built over a decade into a respected premium brand sold through specialty shops and a busy online store. A newcomer, Meridian Ride Co., launches a near-identical line of jerseys under the name MERIDIAN RIDE, sells them on the same online marketplaces, and plans a splashy push timed to a major cycling expo and the Black Friday weekend. Meridian Cyclewear wants the launch stopped before the expo. We will use it to make each abstract step concrete.

A word of orientation before the phases. A preliminary injunction is, in the Supreme Court's words, "an extraordinary remedy never awarded as of right." Winter v. Natural Resources Defense Council, Inc., 555 U.S. 7, 24 (2008); see also Mazurek v. Armstrong, 520 U.S. 968, 972 (1997). You are asking a judge to freeze a competitor's business on an incomplete record, before anyone has proven anything at trial. Courts grant these motions all the time in trademark cases - but only for movants who show up fast, prove the four factors, and hand the court a tightly drawn order it can actually sign. The phases below are built to make you that movant.

Phase 1 - Triage: Should You Move, and How Fast?

Before you draft a word, decide whether a preliminary injunction is the right tool and, if so, on what timetable. The wrong call here wastes money and can hand the defendant a delay defense that haunts the whole case.

• [ ] Confirm that stopping the conduct - not just collecting money - is your real objective. Why: The injunction is the trademark plaintiff's signature remedy precisely because ongoing infringement inflicts harm that money cannot undo: the daily erosion of goodwill and loss of control over how your brand reaches consumers. If what you truly want is a damages number, the emergency machinery may be overkill; the monetary side lives in When You Win and the trademark remedies and monetary recovery toolkit. Trap: Moving for an injunction you do not really need - or cannot really win - burns credibility with the judge you will live with for the rest of the case.

• [ ] Pin down the exact date you discovered the infringement, and start a diligence log. Why: Delay is the single most effective defense to a preliminary injunction. A plaintiff who sat on its rights cannot credibly claim it needs emergency relief now. From this moment, every step you take - investigation, the demand letter, settlement talks - should be dated and documented to show the clock did not simply run while you shrugged. Trap: Unexplained months between discovery and filing can, by themselves, defeat the motion, because they undercut the urgency that justifies extraordinary interim relief - and, under current law, can rebut the statutory presumption of irreparable harm. Authority: Delay as a rebuttal to irreparable harm under 15 U.S.C. § 1116(a); see the full treatment in Stopping the Infringer.

• [ ] Decide your vehicle at a strategic level: TRO, preliminary injunction, or wait for a permanent decree. Why: A TRO is for true fire-alarm urgency (a counterfeit launch timed to a holiday weekend). A preliminary injunction stops the conduct for the duration of the case. If your delay is hard to excuse, you may be better off skipping the emergency stage and aiming your fire at a permanent injunction after trial, where delay matters far less. Pick deliberately; the mechanics of each track follow in later phases. Trap: Reflexively filing a TRO when there is no genuine, imminent, irreparable trigger invites the court to deny it and tells your opponent the urgency is manufactured.

• [ ] Sanity-check the merits: are you likely to win on liability? Why: Likelihood of success on the merits is the factor that has no analog in the permanent-injunction test, and it does most of the work at the preliminary stage. Run a candid likelihood-of-confusion analysis before you move, using the factor-by-factor confusion checklist and the likelihood of confusion toolkit. If the merits are shaky, an injunction is the wrong play. Trap: Falling in love with your own mark. Judges are not impressed by outrage; they are persuaded by similar marks, related goods, overlapping channels, and real confusion.

• [ ] Budget for the bond and the burn rate. Why: Early relief comes at a price. Federal Rule of Civil Procedure 65(c) lets the court require security - a bond - to cover the defendant's losses if the injunction turns out to have been wrongly granted. In a case that would shutter a real business, that figure can run into six or seven figures. Emergency motion practice is also expensive and fast. Know your number before you commit. Authority: Fed. R. Civ. P. 65(c).

• [ ] Confirm the harm is genuinely ongoing or imminent. Why: A preliminary injunction looks forward; it restrains future conduct. If the defendant has already permanently and verifiably stopped, the harm to be enjoined may be gone (though, as Phase 10 explains, "I stopped" rarely moots a permanent injunction).

Meridian in action: Meridian Cyclewear's general counsel learns of MERIDIAN RIDE on October 1 from a confused dealer. She immediately opens a diligence log, has the team buy and photograph a sample jersey, confirms the expo and Black Friday timing, and concludes the merits are strong (near-identical marks, identical goods, same online channels). Because the expo is three weeks out, she chooses to seek a TRO and preliminary injunction together. Diligent, fast, documented - exactly the posture a court rewards.

Phase 2 - Confirm Standing, Ownership, Jurisdiction, and Venue

You cannot enjoin anyone until you establish that you may sue, in this court, over this mark. These are the unglamorous boxes that, left unchecked, produce an embarrassing loss before you ever reach the four factors.

• [ ] Verify you own enforceable rights and confirm the chain of title. Why: Damages and injunctive relief run only to the party that holds the rights. If the mark was assigned, merged, or licensed at any point, the paper trail must put ownership in you today. Pull the assignment history and reconcile it against your registration. Rightsy's assignment recordation checklist and the assignment due-diligence checklist walk the validation. Trap: A gap in the chain of title - an unrecorded assignment, an assignment-in-gross that broke the link to goodwill - can be fatal to standing and is the kind of surprise a defendant loves to spring at the hearing.

• [ ] Identify the precise rights you are asserting: registered, common-law, or both. Why: A federal registration on the Principal Register hands you presumptions of validity, ownership, and nationwide constructive use that make the merits easier; an incontestable registration is even stronger. If you are relying on unregistered rights, your geographic reach is governed by where you actually used the mark. Understand exactly what your registration buys you - see What Federal Registration Actually Buys You - and, for unregistered marks, common-law trademark rights and the common-law rights and geographic scope toolkit. Authority: 15 U.S.C. §§ 1057(b), 1065, 1115 (presumptions and incontestability).

• [ ] Establish subject-matter jurisdiction. Why: Lanham Act claims arise under federal law, so the federal court has jurisdiction regardless of the parties' citizenship. Plead it. Authority: 28 U.S.C. §§ 1331, 1338(a); 15 U.S.C. § 1121.

• [ ] Confirm personal jurisdiction over the defendant. Why: The court must have power over this defendant - through its presence, its sales into the forum, or its targeting of forum consumers. An online seller shipping infringing goods into the district usually supplies the contacts, but do not assume it; analyze it. Trap: Naming a foreign manufacturer over which the court has no jurisdiction, instead of (or in addition to) the domestic distributor you can actually reach.

• [ ] Lay venue in the right district. Why: Venue typically lies where the defendant resides or where a substantial part of the infringing acts occurred - often where the goods are sold or where confusion happens. Authority: 28 U.S.C. § 1391.

• [ ] Decide whom to name - including individuals and intermediaries. Why: Corporate officers who personally directed the infringement can be liable, and a Rule 65(d) order binds not only the named defendant but its officers, agents, employees, and "other persons in active concert or participation" who receive actual notice. Naming the right parties widens the order's reach to the people who can actually make the conduct stop. Authority: Fed. R. Civ. P. 65(d)(2).

• [ ] Screen for the defenses that could defeat the merits before you move. Why: A likelihood-of-success showing must survive the other side's affirmative defenses. Stress-test your motion against abandonment (Use It or Lose It; proving or defeating abandonment), descriptive or nominative fair use, and the equitable defenses (laches, acquiescence, unclean hands). Anticipate them now; do not meet them for the first time at the hearing. Trap: A registration that is vulnerable to cancellation or a mark that may have slipped toward genericness can turn your offensive motion into a defensive scramble.

Phase 3 - Assemble the Evidentiary Record

A preliminary injunction is won or lost on the papers and at a compressed hearing, on a record you build in days, not months. Courts may rely on evidence - including hearsay and declarations - that would not all be admissible at trial, but the more solid your proof, the more confident the judge will be freezing a competitor's business. Build the record deliberately.

• [ ] Marshal the likelihood-of-confusion proof - your merits engine. Why: This is the heart of "likely to succeed." Assemble side-by-side comparisons of the marks (sight, sound, meaning), proof the goods and trade channels overlap, evidence of your mark's strength, and anything showing the defendant's intent. The full apparatus lives in the confusion field map; in the Second Circuit, mind the Polaroid factors at summary judgment. Trap: Treating confusion as obvious. Lay it out factor by factor; do not make the judge assemble your case for you.

• [ ] Document your mark's strength. Why: A strong mark gets a wider berth. Gather evidence of inherent distinctiveness (where your mark sits on the Abercrombie spectrum) and commercial strength - years of use, advertising spend, sales, unsolicited media. If your mark is descriptive, you will need secondary meaning evidence; the Section 2(f) evidence checklist shows what to collect. For the full strength picture, see the distinctiveness and protectability toolkit.

• [ ] Collect every scrap of actual-confusion evidence. Why: Actual confusion is the most persuasive proof that the predicted harm is already happening. Misdirected emails and calls, reviews posted to the wrong brand, social-media mix-ups, confused dealers, returned merchandise - all of it. Even a modest amount, properly authenticated, is potent at the preliminary stage. Trap: Anecdotal "a customer told me they were confused" testimony is hearsay-prone. Capture the underlying documents (the actual misdirected email), and have the confused person declare it where you can.

• [ ] Build the irreparable-harm record - even though you have a presumption. Why: Under the Trademark Modernization Act of 2020, a plaintiff who shows likelihood of success on the merits is entitled to a rebuttable presumption of irreparable harm. But treat the presumption as a powerful default, not a magic word. Reinforce it with concrete evidence of lost control over your brand, exposure to the defendant's (often inferior) quality, and the kind of reputational harm money cannot cleanly repair. Give the court two independent reasons to find irreparable harm, and leave the defendant nothing to rebut. Authority: 15 U.S.C. § 1116(a) (rebuttable presumption added by the TMA); cf. the pre-TMA proof regime of Herb Reed Enterprises, LLC v. Florida Entertainment Management, Inc., 736 F.3d 1239 (9th Cir. 2013), discussed in Stopping the Infringer.

• [ ] Decide whether to commission a survey - and whether there is time. Why: A well-built consumer survey can be the most direct evidence of confusion, and at the preliminary stage even a streamlined survey can move a judge. Weigh cost and the compressed timetable. If you go this route, build it right: a bulletproof consumer survey, the survey methodology checklist, and the consumer survey and expert evidence toolkit. Trap: A rushed, sloppy survey is worse than none - it hands the other side a courtroom demonstration of unreliability and a Daubert challenge.

• [ ] Gather evidence of the defendant's knowledge and bad faith. Why: A defendant who knew of your mark and adopted anyway looks like a deliberate copyist - which supports both an inference of confusion and a broad, strict order. Knowledge of a senior user's rights can destroy a good-faith defense; see Stone Creek v. Omnia and, on the flip side, how a clean clearance search shields a defendant in The Shield of Good Faith.

• [ ] Reduce your proof to admissible declarations and authenticated exhibits. Why: Your motion will be supported by sworn declarations (made under penalty of perjury) and exhibits authenticated through them. Line up declarants - an executive on the brand and harm, a customer or dealer on confusion, an investigator on the defendant's sales, an expert if you have one - and draft tight, fact-specific declarations. Authority: 28 U.S.C. § 1746 (unsworn declarations under penalty of perjury); a verified complaint can itself serve as evidentiary support under Fed. R. Civ. P. 65(b)(1)(A). Trap: Conclusory declarations ("we will suffer irreparable harm") carry no weight. Declarations must state specific, personal-knowledge facts.

Meridian in action: Meridian Cyclewear assembles a side-by-side of the jerseys, a declaration from its VP of brand on a decade of premium positioning and the loss of control it now faces, three misdirected customer emails complaining about MERIDIAN RIDE's poor stitching, a declaration from the confused dealer, and an investigator's declaration documenting the defendant's marketplace listings and the expo plans. It verifies the complaint so the complaint itself can support the TRO.

Phase 4 - Prove the Four Winter Factors

This is the substantive core. A movant must establish all four factors of Winter v. Natural Resources Defense Council, Inc., 555 U.S. 7, 20 (2008). Three of them mirror the eBay permanent-injunction factors; the headline addition at the preliminary stage is the first. Address each one expressly and in order; do not let any factor go dark.

• [ ] Factor 1 - Likelihood of success on the merits. Why: The court has not yet decided who is right, so before it freezes the defendant it wants a credible forecast that you will ultimately win. This is where your full confusion case goes. Show a protectable mark, your priority, and a likelihood of confusion under the governing circuit's multifactor test. Trap: Some circuits demand a strong likelihood of success; a thin merits showing will not be rescued by a dramatic harm story. Lead with your best merits evidence. Authority: Winter, 555 U.S. at 20; multifactor confusion analysis per the field map.

• [ ] Factor 2 - Likelihood of irreparable harm absent relief. Why: You must show you are likely to suffer irreparable harm - not merely that it is possible. Invoke the TMA's § 1116(a) presumption (triggered by your likelihood-of-success showing) and back it with the concrete lost-control and reputational evidence from Phase 3. Trap: Winter killed the "mere possibility" standard. And nothing rebuts irreparable harm faster than your own delay - which is why Phases 1 and 3 insisted you paper the timeline. Authority: Winter, 555 U.S. at 22; 15 U.S.C. § 1116(a).

• [ ] Factor 3 - The balance of equities (hardships) tips in your favor. Why: Weigh what you lose if the court does nothing against what the defendant loses if it acts. Your decade of goodwill bleeding away usually outweighs the defendant's compliance costs - especially because a defendant cannot count the cost of stopping its own infringement as a hardship. That expense is self-inflicted. Trap: A genuinely good-faith defendant facing disproportionate, non-infringement-related harm can use this factor to narrow the order (a phase-out, a tighter geography). Concede nothing, but anticipate it. Authority: Winter, 555 U.S. at 24; self-inflicted-harm principle discussed in Stopping the Infringer.

• [ ] Factor 4 - An injunction serves the public interest. Why: Trademark law is consumer-protection law; the public has a powerful interest in not being deceived about who makes what. In the ordinary case this is the plaintiff's easiest factor. Trap: Two public interests can cut the other way - free expression (parody, commentary, expressive use) and competition (an overbroad order that monopolizes a word or chokes lawful rivalry). If the defendant's use has any expressive dimension, meet it head-on. Authority: Winter, 555 U.S. at 20, 24.

• [ ] Know how your circuit combines the factors - sequential or sliding scale. Why: Some circuits treat each factor (especially irreparable harm) as an independent requirement. Others apply a sliding scale under which a strong showing on one factor offsets a weaker showing on another. The Ninth Circuit, for example, preserved a "serious questions going to the merits" formulation so long as the balance of hardships tips sharply for the movant and the other factors are met. Authority: Alliance for the Wild Rockies v. Cottrell, 632 F.3d 1127 (9th Cir. 2011). Trap: Allocating your emphasis for the wrong circuit. Confirm the controlling formulation before you decide which factor to lean on hardest.

• [ ] Flag whether you are seeking a prohibitory or a mandatory injunction. Why: An order that simply tells the defendant to stop (prohibitory) preserves the status quo and is the norm. An order compelling affirmative action that changes the status quo (mandatory) - a recall, a forced rebrand mid-stream - draws heightened scrutiny in several circuits. Frame your request as preserving the last peaceable status quo wherever you can.

Phase 5 - If You Need It Now: The TRO Track (Rule 65(b))

When the harm is so imminent that you cannot wait even for a preliminary-injunction hearing - the classic case being a counterfeit or copycat launch timed to a holiday or event - you seek a temporary restraining order first. The TRO holds the line for a few days until the court can convene a full hearing. It runs on the same equitable instincts as a preliminary injunction but with heightened procedural safeguards.

• [ ] Decide whether you are seeking the TRO with or without notice. Why: Courts strongly prefer notice. A TRO without notice - ex parte - is reserved for situations where giving the defendant warning would itself cause the irreparable harm (the counterfeiter who would dump inventory and shred records overnight) or where the defendant truly cannot be reached in time. Authority: Fed. R. Civ. P. 65(b)(1).

• [ ] For an ex parte TRO, satisfy both Rule 65(b)(1) prerequisites. Why: The Rule permits an ex parte TRO only if (A) specific facts in an affidavit or a verified complaint clearly show that immediate and irreparable injury will result before the adverse party can be heard, and (B) the movant's attorney certifies in writing any efforts made to give notice and the reasons why notice should not be required. Both are mandatory. Trap: A boilerplate certification, or a declaration that gestures vaguely at urgency, gets ex parte relief denied. Be specific about why notice would defeat the relief. Authority: Fed. R. Civ. P. 65(b)(1)(A)-(B).

• [ ] Respect the TRO's short clock and calendar the preliminary-injunction hearing immediately. Why: An ex parte TRO expires after the period the court sets, not to exceed 14 days, though the court may extend it once for a like period for good cause (or longer with the adverse party's consent). The TRO is a bridge, not a destination; the moment you get one, you should be racing toward the preliminary-injunction hearing. Authority: Fed. R. Civ. P. 65(b)(2); see Granny Goose Foods, Inc. v. Brotherhood of Teamsters, 415 U.S. 423 (1974).

• [ ] Understand a TRO's limited appealability. Why: Unlike a preliminary injunction, a TRO is generally not immediately appealable. That cuts both ways: you cannot appeal a denied TRO, but neither can the defendant tie you up on appeal over the short-fuse order. (A TRO that functions like a preliminary injunction - extended and adversarial - may be treated as appealable.) Authority: Contrast 28 U.S.C. § 1292(a)(1) (preliminary injunctions appealable).

• [ ] Be ready to post security on a TRO too. Why: Rule 65(c)'s bond requirement applies to TROs as well as preliminary injunctions. Have your security lined up before you ask. Authority: Fed. R. Civ. P. 65(c).

Meridian in action: With the expo three weeks out, Meridian Cyclewear seeks a TRO with notice - it can reach Meridian Ride's U.S. counsel, so it has no ex parte justification. Its verified complaint and declarations show that an expo launch would flood the premium market with confusingly branded jerseys before any full hearing. The court enters a short TRO barring expo sales and sets the preliminary-injunction hearing for ten days out.

Phase 6 - Draft the Motion, Brief, and (Critically) the Proposed Order

Now you build the package the judge will actually rule on. Sloppy drafting loses winnable motions; precise drafting, especially of the proposed order, is where craft pays off.

• [ ] File the complaint (verified) and the notice of motion. Why: The injunction motion rides on a pending lawsuit. A verified complaint does double duty as evidentiary support for the TRO/PI. For the full pleading workup - claims, parties, jurisdictional allegations - use the federal infringement complaint checklist. Trap: Pleading claims in the complaint that your injunction brief then ignores, or vice versa. Keep the theories aligned.

• [ ] Write a memorandum of law organized around the four Winter factors. Why: Give the court a clean, factor-by-factor roadmap, each section anchored to your declarations and exhibits by pin cite. Lead with likelihood of success; do not bury it. Trap: Exceeding local page limits or ignoring required formatting. Many districts cap brief length and require a specific structure - check the local rules and the judge's individual practices first.

• [ ] Attach the supporting declarations and a clean, indexed set of exhibits. Why: Every factual assertion in the brief should trace to a declaration paragraph or an exhibit. An organized exhibit index makes the judge's job easy and your case credible.

• [ ] Draft the proposed order with Rule 65(d) specificity - this is the make-or-break document. Why: Rule 65(d)(1) requires every injunction to (A) state the reasons it issued, (B) state its terms specifically, and (C) describe in reasonable detail - not by referring to the complaint or another document - the acts restrained or required. The enjoined party must know exactly what it may not do, because crossing the line means contempt. A vague or sprawling order is vulnerable on appeal and hard to enforce. Trap: "Defendant shall cease all infringement" is unenforceable mush. Name the marks, the conduct, the goods, and the territory with precision. Authority: Fed. R. Civ. P. 65(d)(1).

• [ ] Tailor the scope to the proven confusion - geography and conduct. Why: Ask for relief that tracks the confusion and no further. Where the parties meet on national marketplaces, broad or nationwide relief is appropriate; where the conflict is genuinely local, it is not. Overreaching invites a narrower order or reversal. The geographic-scope lodestar is Guthrie Healthcare System v. ContextMedia, Inc., 826 F.3d 27 (2d Cir. 2016) (do not artificially confine an injunction below the reach of likely confusion); the mirror-image limit is the Dawn Donut rule, and the broader geography of unregistered rights is mapped in where your trademark rights end and Tea Rose-Rectanus.

• [ ] Consider building in a safe-distance provision and affirmative cleanup. Why: A proven infringer should not be able to resume the confusion through a cosmetic tweak - dropping a letter, swapping a color. A safe-distance provision requires it to steer well clear. Where warranted, you can also request a recall, corrective notices, or disabling of infringing listings. Authority: Safe-distance rule, e.g., Innovation Ventures, LLC v. N.V.E., Inc., 694 F.3d 723 (6th Cir. 2012). Trap: At the preliminary stage, mandatory cleanup (recalls, destruction) is harder to obtain than a simple "stop." Calibrate your ask to what a court will grant before final judgment.

• [ ] Include your proposed bond figure and the argument for it. Why: Do not leave the bond to the defendant. Propose a modest, well-supported number and build a record that the defendant's realistic downside from a correct injunction is limited. Authority: Fed. R. Civ. P. 65(c).

• [ ] Request an expedited briefing schedule and a hearing date. Why: Urgency is your theme; ask the court to set a fast schedule. If you obtained a TRO, the preliminary-injunction hearing must be set within the TRO's life.

• [ ] Prepare proposed findings of fact and conclusions of law. Why: When a court grants or denies an interlocutory injunction it must state findings and conclusions supporting its action. Handing the judge a well-drafted set makes a favorable, appeal-proof order more likely. Authority: Fed. R. Civ. P. 52(a)(2).

Phase 7 - Prepare for the Bond (Rule 65(c))

The bond is the price of early relief and a live tactical battleground. Handle it deliberately rather than as an afterthought the judge raises from the bench.

• [ ] Estimate the defendant's realistic loss from a correct injunction. Why: The bond exists to compensate a party "wrongfully enjoined or restrained." The court sets the amount by estimating what the defendant would lose if the injunction were later found improper. The smaller and more speculative that downside looks, the smaller the bond. Authority: Fed. R. Civ. P. 65(c).

• [ ] Argue affirmatively for a modest figure. Why: Where the potential harm to the defendant is limited, or your case looks overwhelming, courts sometimes set a nominal bond. Make that record: the defendant is a new entrant, its sales are small, its costs of compliance are self-inflicted. Trap: Saying nothing and letting the defendant frame the bond as the cost of shuttering a thriving business. A high bond can deter your own motion.

• [ ] Line up the security instrument in advance. Why: If the order issues conditioned on a bond, the injunction is not effective until you post it. Have the surety bond or cash deposit ready so there is no gap during which the defendant keeps selling.

• [ ] Remember the bond attaches only to preliminary relief. Why: A permanent injunction entered after final judgment needs no bond, because the merits have been adjudicated and there is no longer a meaningful risk of a "wrongful" injunction.

Meridian in action: Meridian Ride argues for a $750,000 bond, painting an injunction as the death of its launch. Meridian Cyclewear counters that the defendant is a three-month-old entrant with modest sales, that most of its claimed losses are the self-inflicted cost of ceasing infringement, and that the merits are overwhelming. The court sets a $40,000 bond - a number Meridian Cyclewear has already arranged to post the same afternoon.

Phase 8 - File, Serve, and Seek Expedited Discovery and a Hearing

With the papers built, you move into execution: getting the motion before the judge, the defendant properly notified, and - often - fast discovery to fortify the record before the hearing.

• [ ] File the motion package and pay the fees. Why: Self-explanatory, but confirm the complete set is filed together - complaint, motion, brief, declarations, exhibits, proposed order, and any TRO papers - per local e-filing rules.

• [ ] Serve the defendant and satisfy notice obligations. Why: A preliminary injunction may issue only on notice to the adverse party. Effect service of the summons and complaint and give notice of the motion and hearing. (The TRO track in Phase 5 governs the narrow ex parte exception.) Authority: Fed. R. Civ. P. 65(a)(1).

• [ ] Check whether a pre-motion conference or meet-and-confer is required. Why: Many judges require the parties to confer, or require a pre-motion letter, before an injunction motion. Skipping a required step can get your motion bounced on procedure. Trap: Assuming the Federal Rules are the whole story. Local rules and individual judges' practices add requirements - courtesy copies, chambers notification for emergency motions, specific exhibit formats. Read them first.

• [ ] Move for expedited discovery if you need it to solidify the record. Why: Ordinarily no discovery may occur before the Rule 26(f) conference, but a court may authorize expedited discovery for good cause - targeted document requests, a short deposition, sales data - to firm up confusion or harm before the hearing. In a fast injunction posture this can be decisive. Authority: Fed. R. Civ. P. 26(d)(1). Trap: Asking for sprawling, merits-wide discovery. Keep expedited requests narrow and tied to the injunction factors, or the court will deny them as overbroad.

• [ ] Preserve evidence and remember the disclosure sanctions that police it. Why: Both sides must preserve relevant materials, and evidence not properly disclosed can be excluded. Undisclosed evidence is policed by the self-executing sanction of Rule 37(c)(1); see The Self-Executing Sanction.

• [ ] Consider asking to consolidate the hearing with a trial on the merits. Why: Rule 65(a)(2) lets the court advance and consolidate the trial on the merits with the preliminary-injunction hearing. In a clean case this can convert a preliminary fight into a final resolution - efficient, but only wise when your full record is ready. Authority: Fed. R. Civ. P. 65(a)(2). Trap: Consolidating before you are trial-ready, or being ambushed by the defendant's request to consolidate when you are not ready. Insist on adequate notice.

Phase 9 - Win the Hearing

The preliminary-injunction hearing is frequently where the war is actually won. Factual findings made here draw deferential review on appeal, and the practical outcome of the case is often settled by the preliminary ruling. Treat the hearing as the main event.

• [ ] Confirm the hearing's format: argument only, or live evidence. Why: Some judges decide on the papers and argument; others hold an evidentiary hearing with live witnesses and cross-examination. Ask chambers. Your preparation differs enormously between the two. Trap: Showing up ready to argue and discovering the judge expects live witnesses - or vice versa.

• [ ] Prepare your witnesses for direct and cross. Why: If the hearing is evidentiary, your declarants may testify and be cross-examined. A brand executive who crumbles on the harm testimony, or an expert who cannot defend the survey, can sink the motion. Prepare them as you would for trial, compressed.

• [ ] Be ready to defend - and adjust - the scope and the bond in real time. Why: Judges frequently negotiate the order's terms from the bench: narrowing geography, adding a short phase-out, setting the bond. Walk in with fallback positions you can live with so you are shaping the order rather than reacting to it.

• [ ] Meet the defendant's anticipated counterattacks. Why: Expect the defense to press delay (to rebut irreparable harm), to attack the merits and your surveys, to argue good faith and disproportionate hardship, and to demand a big bond. The full defensive arsenal is catalogued in the answer and defenses checklist; read it as your opponent's script.

• [ ] Remember the injunction is decided by the judge, sitting in equity - there is no jury here. Why: Injunctive relief is equitable; the court, not a jury, finds the facts that support it. That shapes how you present - you are persuading one careful reader, not a panel. The allocation of issues between judge and jury is worth understanding before you walk in.

• [ ] Hand up your proposed findings and a revised order reflecting the argument. Why: Make it easy for the court to rule your way and to write an order that survives appeal. A judge who can adopt your well-drafted findings is a judge more likely to grant the motion. Authority: Fed. R. Civ. P. 52(a)(2), 65(d).

Phase 10 - After the Order: Post, Enforce, Appeal, or Regroup

The ruling is not the finish line. Whether you won or lost, several time-sensitive moves follow.

If the Injunction Is Granted

• [ ] Post the bond immediately and serve the signed order. Why: The injunction typically takes effect only once security is posted, and the order binds non-parties (agents, distributors, marketplaces) only once they receive actual notice. Serve it promptly and broadly. Authority: Fed. R. Civ. P. 65(c), (d)(2).

• [ ] Calendar every deadline and monitor compliance. Why: An injunction is only as strong as your willingness to police it. Watch the market and the defendant for cosmetic workarounds or quiet resumption - exactly what the safe-distance provision exists to catch. Treat post-order surveillance as part of the remedy, not an afterthought; a standing brand-watch program (the kind built into Rightsy's tools) turns a paper order into a live one.

• [ ] Be ready to enforce through contempt. Why: A defendant that violates the order can be held in civil contempt and hit with compensatory sanctions, coercive fines, and fees. Document any breach and be prepared to march back into court.

• [ ] Decide whether to push the conduct off the internet through parallel channels. Why: For online infringement, a court order pairs well with platform takedowns and border enforcement. Consider the online brand protection and anti-counterfeiting toolkit, a DMCA takedown, a UDRP complaint for an infringing domain, or recording your mark with U.S. Customs to choke off counterfeit imports.

If the Injunction Is Denied

• [ ] Remember a denial is a setback, not a death sentence. Why: A denied preliminary injunction is not a ruling on the merits. The case continues, and you can still win a permanent injunction at the end - where the delay concern that may have sunk interim relief carries far less weight.

• [ ] Preserve and pursue your monetary remedies. Why: Your claims for the defendant's profits and your actual damages survive a denied injunction; see When You Win, the damages and profits evidence checklist, and apportionment. Fees in an exceptional case are covered in Who Pays the Lawyers.

• [ ] Consider an immediate interlocutory appeal. Why: An order granting or denying a preliminary injunction is appealable as of right, even though it is interlocutory. If the district court applied the wrong legal standard, you can seek prompt reversal rather than waiting out the whole case. Review is for abuse of discretion, with legal conclusions reviewed de novo and factual findings for clear error - see standards of review on appeal. Authority: 28 U.S.C. § 1292(a)(1).

• [ ] Renew the motion if circumstances change. Why: A denial on the existing record does not foreclose relief on a stronger one. Escalating harm, an expanding infringement, or fresh confusion evidence can support a renewed motion.

Either Way

• [ ] Re-evaluate settlement, including a consent injunction. Why: The gravitational pull of a pending suit - and a preliminary ruling, however it came out - frequently moves the parties toward settlement. A consent injunction carries the same contempt teeth as a litigated one but lets the parties bargain the terms (a phase-out, defined lanes of use, a coexistence arrangement). See the settlement and coexistence agreement checklist and the forthcoming guide to coexistence and settlement agreements. Trap: A consent order still must satisfy Rule 65(d)'s specificity requirement and will be construed by its own words in any later compliance fight. Draft it as carefully as a litigated order.

Meridian in action: The court grants the preliminary injunction, finding a strong likelihood of success, the TMA presumption of irreparable harm unrebutted, the hardships tilted against the self-inflicted costs of stopping, and the public interest in avoiding deception clear. Meridian Cyclewear posts the $40,000 bond that afternoon, serves the order on Meridian Ride and the marketplaces hosting its listings, and the listings come down within 48 hours. Six weeks later, facing the expense of a full case and a permanent injunction it is unlikely to escape, Meridian Ride settles on a consent decree: it rebrands to a non-confusing name, keeps a safe distance from MERIDIAN, and winds down old inventory over 60 days.

A Compressed Two-Timeline Lesson

The same facts can produce opposite results depending on one variable: speed. Hold everything about Meridian constant except the plaintiff's diligence.

Timeline A - the diligent plaintiff (above). Meridian Cyclewear discovers the use, investigates in days, sends a demand, and moves within weeks. Its urgency is believable, the TMA presumption does the heavy lifting on irreparable harm, and it wins the preliminary injunction that effectively ends the dispute.

Timeline B - the plaintiff who waited. Change one fact: Meridian Cyclewear learns of MERIDIAN RIDE and does nothing for two years while the newcomer builds a real business - hires staff, signs dealers, accumulates its own following. Only then does it move. Now the long, unexplained delay rebuts the presumption of irreparable harm and guts the claim of urgency: a company that tolerated the use for two years cannot credibly say it needs emergency relief. The court may deny the preliminary injunction, leaving Meridian Cyclewear to pursue a permanent injunction at the end - where delay matters less, but where it has also let the infringer entrench. Same marks, same goods, same strong infringement case - and a very different result at the stage that usually decides everything.

The lesson is the whole point of this checklist: the preliminary injunction rewards the brand owner who moves fast and proves it moved fast. Speed is not just good lawyering; it is a substantive element of the remedy.

Common Mistakes

• Sleeping on your rights, then sprinting to court. Unexcused delay is the defense most likely to defeat a preliminary injunction even on a strong infringement case, because it rebuts irreparable harm and destroys the urgency that justifies extraordinary relief. Move promptly and document why any delay was reasonable.
• Treating the injunction as automatic. Since eBay, there are no automatic injunctions. You must prove all four Winter factors with evidence, not assert them.
• Leaning entirely on the TMA presumption. The § 1116(a) presumption is rebuttable. Build a real irreparable-harm record so the court has two reasons to grant relief and the defendant has nothing to rebut.
• A vague proposed order. "Cease all infringement" violates Rule 65(d) and is unenforceable. Specify the marks, conduct, goods, and territory in detail.
• Overreaching on scope. Asking for relief broader than the proven confusion invites a narrower order, a bigger bond, or reversal. Tailor geography and conduct to the actual harm.
• Ignoring the bond until the judge raises it. Propose a modest figure, build the record for it, and have the security ready to post so there is no gap in protection.
• Forgetting the local rules and the judge's individual practices. Page limits, meet-and-confer requirements, emergency-motion protocols, and exhibit formats vary by district and judge. A procedural foot-fault can sink a winnable motion.
• Conclusory declarations. "We will be irreparably harmed" proves nothing. Declarations must state specific facts within the declarant's personal knowledge.
• A rushed, sloppy survey. A poorly designed survey is worse than none; it hands the defendant a Daubert exhibit. Build it right or skip it.
• Mishandling the ex parte certification. An ex parte TRO requires a specific factual showing and an attorney certification explaining why notice should be excused. Boilerplate gets it denied.
• Naming the wrong defendant. Suing an unreachable foreign manufacturer instead of the domestic distributor you can actually enjoin - or omitting the officers and intermediaries a Rule 65(d) order would bind.
• Skipping the chain-of-title check. A gap in ownership is a standing surprise waiting to happen. Confirm you own the mark today before you move.
