Declaratory Judgment Checklist: Case or Controversy, Venue, and the Race to the Courthouse

By Casey Scott McKay · 2023-11-02

Fourteen phases that take a threatened party from the demand letter on the desk to a judgment, a covenant, or a coexistence agreement. The order is deliberate and it is not the order most people use: forum before merits, jurisdiction before drafting, and a documented negotiation before any complaint is filed. You get a nine-item controversy evidence package, the ripeness test that kills pre-launch filings, a forum-contacts investigation plan, a five-step timing protocol that defeats the anticipatory-filing characterization, model complaint language for the controversy, jurisdiction, ripeness, and cancellation allegations, and a covenant-not-to-sue attack sequence. The mark owner's five responsive motions are ranked by cost and probability. One invented matter, Barrow Field Optics v. Kestrel Instruments, runs through every phase.

Summary. Fourteen phases that take a threatened party from the demand letter on the desk to a judgment, a covenant, or a coexistence agreement. The order is deliberate and it is not the order most people use: forum before merits, jurisdiction before drafting, and a documented negotiation before any complaint is filed. You get a nine-item controversy evidence package, the ripeness test that kills pre-launch filings, a forum-contacts investigation plan, a five-step timing protocol that defeats the anticipatory-filing characterization, model complaint language for the controversy, jurisdiction, ripeness, and cancellation allegations, and a covenant-not-to-sue attack sequence. The mark owner's five responsive motions are ranked by cost and probability. One invented matter, Barrow Field Optics v. Kestrel Instruments, runs through every phase.

What this checklist is for

This is the working document for the lawyer holding a cease-and-desist letter and deciding whether to answer it or sue on it. It does not re-teach the doctrine. If you cannot say in one sentence why MedImmune, Inc. v. Genentech, Inc., 549 U.S. 118 (2007) made the old reasonable-apprehension test obsolete, read Suing First: Declaratory Judgment Actions in Trademark Disputes first. The reasoning behind each box below — why the forum question comes before the merits question, why a covenant not to sue is both a defeat and an opportunity, why filing on the deadline is the one thing never to do — is in Filing or Defeating a Declaratory Judgment Action. This document tells you what to do, in order.

Who should use it. Counsel for a business that has been threatened over a brand it is already using; in-house counsel deciding whether to spend $150,000 to control a forum; mark owners' counsel who want to know what their letter just enabled; and anyone who has to explain to a board why the company is about to become a plaintiff in a case it did not want.

What you'll need before you start. The demand letter with its transmission record and every enclosure; copies of any letters the mark owner sent to your client's customers, retailers, distributors, or platforms; your client's first-use, sales, and marketing records for the accused mark; the mark owner's registration certificates and full USPTO file histories; TSDR status for every asserted registration; a TTAB docket search for pending proceedings between the parties; and written budget authority, because the answer to "should we file?" is different at $80,000 than at $400,000.

The worked matter. Barrow Field Optics, Inc., a Bozeman, Montana maker of spotting scopes and rangefinders with $23 million in revenue, launched KESTREL RIDGE binoculars eight months ago; the line now runs $4.1 million a year through two national outdoor retailers. Kestrel Instruments, LLC, a Connecticut company, owns KESTREL for handheld weather meters (registered 2009, in use) and KESTREL for optical instruments (registered 2019 under Section 44(e), no discoverable U.S. use). Its letter asserts infringement and dilution, demands cessation and destruction of inventory within twenty-one days, threatens immediate injunctive relief, and was copied to both of Barrow Field's retailers.

| Phase | What you accomplish | Typical elapsed time | |---|---|---| | 1 | Preserve, docket, and open the file | 1-2 days | | 2 | Confirm an actual controversy exists | 2-3 days | | 3 | Confirm your own client's conduct is ripe | 2-3 days | | 4 | Investigate the mark owner's forum contacts | 1-2 weeks | | 5 | Choose the forum, honestly | 3-5 days | | 6 | Audit the asserted registrations | 1-2 weeks | | 7 | Run the timing protocol; document the impasse | 4-8 weeks | | 8 | Draft the complaint and its counts | 2-3 weeks | | 9 | File, serve, and notify the Board | 1-2 weeks | | 10 | Oppose the motions to dismiss or transfer | 2-5 months | | 11 | Analyze and attack the covenant not to sue | 3-6 weeks | | 12 | Discovery on the four targets that decide it | 6-14 months | | 13 | Settle, and get the terms that are worth having | 1-4 months | | 14 | Build and file the fee application | 2-4 months |

Phase 1 — Preserve, docket, and open the file

[ ] Calendar the deadline stated in the letter, and calendar a date five business days earlier as the internal decision date.
- Why. Every option in this checklist requires a decision before the deadline, including the decision to ask for more time. A file that reaches the deadline without a decision has already chosen the worst branch.
[ ] Issue a litigation hold covering brand-selection files, clearance searches, sales and marketing records for the accused mark, communications with retailers and distributors, and any prior contact with the mark owner.
- Trap. The brand-selection file is the first thing the mark owner will ask for and the most common place a bad document lives — the internal email observing that "the other Kestrel might be a problem, let's move fast." Find it now, while you still control the narrative about it.
[ ] Preserve the letter itself with its envelope, courier record, or email headers, and note the date and manner of receipt.
[ ] Contact each customer, retailer, distributor, or platform that received a copy. Ask for the letter and for any internal response, and ask now.
- Why. Retailers cooperate when the relationship is warm. Six months into litigation they have lawyers who advise them to stay out of it.
[ ] Pull TSDR records and full file histories for every asserted registration, and print status pages the day you pull them.
[ ] Search TTAB records for any proceeding between the parties, and search PACER for the mark owner's litigation history.
- Why. A mark owner with ten prior suits is credible when it threatens; one with forty letters and no filings is telling you something different. Both facts matter later — the first to your client's risk assessment, the second to a fee application.
[ ] Ask the client the two questions that shape everything: how much is this line worth, and could you live with a name change?
- Trap. Counsel who never asks the second question spends $200,000 defending a mark the client would have abandoned for $30,000 in rebranding cost. See Changing the Name on the Door.

Barrow Field, Phase 1. Letter received 14 March; deadline 4 April; internal decision date 28 March. Hold issued 15 March. Both retailers produce their copies of the letter within a week; one attaches an internal email asking whether to pull the SKU pending resolution. That email is now the most valuable document in the case.

Phase 2 — Confirm an actual controversy exists

[ ] Test the letter against the totality standard: is there a substantial controversy, between parties with adverse legal interests, of sufficient immediacy and reality to warrant a declaratory judgment?
- Authority. 28 U.S.C. § 2201(a); MedImmune, Inc. v. Genentech, Inc., 549 U.S. 118, 127 (2007); Maryland Casualty Co. v. Pacific Coal & Oil Co., 312 U.S. 270, 273 (1941); Aetna Life Insurance Co. v. Haworth, 300 U.S. 227, 240-41 (1937).
[ ] Score the nine controversy indicators present in your file, in descending weight: an express assertion of infringement; a demand to cease; a stated deadline; an express or implied threat of suit; communications to the client's customers or platforms; a pending Board proceeding; a marketplace takedown; a pattern of enforcement against similarly situated parties; and prior litigation on the same mark.
[ ] Identify what your file lacks and whether the gap is fatal. Three or more of the nine, including an assertion and a demand, is comfortably sufficient after MedImmune.
[ ] Confirm the letter concerns your client's actual goods and services, not a hypothetical extension.
[ ] If the only communication is a licensing inquiry or a request for information, stop.
- Trap. A polite letter asking "do you have a license?" with no assertion of infringement is thin ground. Filing on it invites a dismissal and hands the mark owner the reasonable-party role for the rest of the dispute.
- Authority. Compare Surefoot LC v. Sure Foot Corp., 531 F.3d 1236, 1244-49 (10th Cir. 2008) (five years of demands and Board proceedings supplied a controversy).
[ ] Where the file is thin, consider writing a response that asks the mark owner to state its position clearly. A specific answer supplies what the file lacks.

Barrow Field, Phase 2. Seven of nine indicators: assertion, demand, deadline, injunction threat, retailer letters, and a pattern (four other letters located through counsel's industry contacts). Not close.

Phase 3 — Confirm your own client's conduct is ripe

[ ] Confirm the accused conduct exists in fact: shipped goods, invoices, revenue, and a live listing.
[ ] Where the launch has not happened, test imminence: manufactured inventory, executed retail or distribution agreements, committed tooling and packaging spend, a filed application, and a launch date backed by contracts.
[ ] Where the client has only a shortlisted name, a concept, or an intention, do not file.
- Why. A declaration about conduct that may never occur is an advisory opinion, and courts decline them. The dismissal costs the filing fee and the forum.
[ ] Quantify the ripeness facts in numbers you can plead: months of sales, dollars of revenue, named retailers, units shipped, and committed spend.
[ ] Where ripeness is genuinely doubtful, consider the alternatives: a Board petition to cancel, which has no ripeness problem of this kind; a negotiated coexistence approach; or waiting for the mark owner to move.
- See. Filing a Petition for Cancellation; Federal Court vs. TTAB.

Barrow Field, Phase 3. Eight months of sales, $4.1 million trailing revenue, two national retailers, $780,000 in committed tooling and packaging. Ripe on any view.

Phase 4 — Investigate the mark owner's forum contacts

[ ] Start from the rule you must overcome: a demand letter sent into a forum generally does not by itself subject the sender to personal jurisdiction there.
- Authority. Red Wing Shoe Co. v. Hockerson-Halberstadt, Inc., 148 F.3d 1355, 1360-61 (Fed. Cir. 1998). Regional circuit law governs a trademark case, but the principle is widely followed.
[ ] Plead and prove the defendant's contacts, not your client's injury.
- Authority. Walden v. Fiore, 571 U.S. 277, 284-91 (2014); Burger King Corp. v. Rudzewicz, 471 U.S. 462, 475-76 (1985).
- Trap. "Defendant knew our client is here and aimed the harm here" is the theory Walden rejected. It is also the theory most declaratory complaints still plead.
[ ] Run the contacts investigation: test purchases into the forum; dealer locator and distributor records; state business and tax registrations; registered agent filings; trade-show exhibitor lists; the mark owner's own website shipping and dealer pages; and any past litigation in the district.
[ ] Treat enforcement conduct directed into the forum as a distinct contact — letters to the client's forum-based retailers, takedowns aimed at forum sales, or communications to forum customers.
- Why. This is frequently the strongest jurisdictional fact available, and it exists only because the mark owner chose to copy third parties.
[ ] Assemble declarations and documentary exhibits before drafting, not after the motion to dismiss arrives.
[ ] Where the record is thin but not empty, plan to request jurisdictional discovery. It is routinely granted and it buys three to five months.
[ ] Where the record is empty, accept it and move to Phase 5 with the home district off the table.

Barrow Field, Phase 4. Kestrel Instruments has no Montana office, employee, or registration. Its weather meters reach four Montana dealers through a national distributor; counsel documents two test purchases. The retailer letters are the core of the jurisdictional case.

Phase 5 — Choose the forum, honestly

[ ] List the candidate districts: the client's home district; the mark owner's home district; and any district with a genuine connection through manufacture, sales volume, or the mark owner's operations.
[ ] For each, score four things: probability of surviving a jurisdictional challenge; the circuit's likelihood-of-confusion factors; local practice on preliminary injunctions and scheduling; and time to trial.
- See. Trademark Litigation Toolkit for the circuit-by-circuit factor tests, and Proving Likelihood of Confusion for what the factors do.
[ ] Confirm venue independently of jurisdiction under 28 U.S.C. § 1391(b), and subject-matter jurisdiction under 28 U.S.C. § 1338(a).
[ ] Write the honest recommendation in a memo, including the case for not filing at all.
- Why. If jurisdiction at home is doubtful, filing there buys a transfer motion, a three-month delay, and a worse narrative. Filing where jurisdiction is secure — even the mark owner's district — still buys timing, framing, and the plaintiff's posture, which are real but smaller.
[ ] Present the client a three-branch decision: file at home and accept jurisdictional risk; file where jurisdiction is certain and take the smaller advantage; or respond and negotiate without filing.

Barrow Field, Phase 5. Ninth Circuit Sleekcraft factors, a district with Barrow Field's operations, and a jurisdictional theory resting on the retailer letters plus distributor sales. Counsel recommends filing in Montana with jurisdictional discovery budgeted at $35,000.

Phase 6 — Audit the asserted registrations

[ ] For each asserted registration, pull the file history and check: the filing basis; the specimens of record; the declarations of use and their supporting evidence; the identification of goods; and whether any goods appear unused.
[ ] Flag Section 44(e) and Section 66(a) registrations, which issue without proof of U.S. use and are the most common source of unused goods on the register.
- Authority. 15 U.S.C. § 1126(e); 15 U.S.C. § 1141f.
[ ] Run a use investigation for each asserted class: website, marketplaces, dealer network, trade press, archived pages, and a test purchase attempt.
[ ] Where the investigation shows no use, price the three routes: a cancellation count under 15 U.S.C. § 1119 in the declaratory action; a Board petition under 15 U.S.C. § 1064; or an expungement or reexamination petition, which is the cheapest.
- See. Cleaning the Register; Filing an Expungement or Reexamination Petition; Trademark Abandonment Evidence Checklist.
[ ] Check whether the mark owner's declarations of use were accurate. Material misstatements support a fraud theory, though the standard is intent to deceive and it is demanding.
- Authority. In re Bose Corp., 580 F.3d 1240, 1245 (Fed. Cir. 2009).
[ ] Note incontestability status under 15 U.S.C. § 1065 and which defenses survive it under § 1115(b).

Barrow Field, Phase 6. The optical-instruments registration is a Section 44(e) filing with no U.S. use found anywhere. That single fact reframes the dispute: the strongest part of the demand rests on the weakest registration.

Phase 7 — Run the timing protocol and document the impasse

[ ] Send a substantive response within the letter's deadline, addressing the merits — the goods difference, the absence of confusion evidence, the registration defects, and any defense.
- See. Responding to a Cease-and-Desist Letter.
[ ] Ask for an extension in writing, or propose a call, and document the request and the answer.
[ ] Engage genuinely for a defined period — four to eight weeks — and make at least one concrete proposal.
[ ] Paper the impasse when it arrives: a short letter reciting the exchanges, the proposals, and the refusal.
[ ] Do not file on or immediately before the deadline.
- Why. A complaint filed on deadline day, in a forum with no connection to the client, in response to a letter that named the court where suit would be brought, is the paradigm anticipatory filing. Trial courts have broad discretion under the first-filed rule and use it. Kerotest Manufacturing Co. v. C-O-Two Fire Equipment Co., 342 U.S. 180, 183-85 (1952).
[ ] Name the tension for the client in writing: every week of engagement is a week the mark owner may file first.
- Trap. Where the mark owner has said it will sue on a date certain, this protocol may not be available. The choice then is to file and defend the characterization, or to accept the defendant's chair. Both are legitimate; only the unconsidered version is malpractice.
[ ] Keep the negotiation correspondence in a form you are willing to attach to an opposition brief.

Barrow Field, Phase 7. Substantive response 28 March. Extension to 25 April granted and confirmed by email. Coexistence proposal — Barrow Field limits KESTREL RIDGE to binoculars and spotting scopes, no weather instruments, no overlap in trade channels — sent 10 April, refused without counter 22 April. Complaint filed 6 May, twelve days after impasse and thirty-two days after the original deadline.

Phase 8 — Draft the complaint and its counts

[ ] Plead the controversy with the letter attached as an exhibit, quoting the assertion, the demand, the deadline, and the litigation threat, and citing MedImmune.
[ ] Plead the ripeness facts in numbers: dates, revenue, retailers, committed spend.
[ ] Plead the defendant's forum contacts specifically, with exhibits: the enforcement communications into the district, the sales into the district, and any commercial relationship.
[ ] Include Count I, declaration of non-infringement under 28 U.S.C. § 2201.
[ ] Include Count II, declaration of no dilution, only if dilution was actually threatened, and check whether the mark plausibly meets the famousness standard.
- Authority. 15 U.S.C. § 1125(c)(2)(A). See Trademark Dilution Claim Checklist.
[ ] Include the cancellation count under 15 U.S.C. § 1119, pleading injury from the registration's continued existence separately from injury from the threat.
- Why. This is the count a covenant not to sue cannot moot. It converts a defensive filing into leverage.
[ ] Add affirmative claims where the facts support them: tortious interference for customer letters that caused a retailer to cancel or delay; false advertising under 15 U.S.C. § 1125(a)(1)(B) where statements to third parties misdescribed the client's goods; and state unfair competition.
- Authority. Lexmark International, Inc. v. Static Control Components, Inc., 572 U.S. 118 (2014) (zone of interests and proximate cause). See False Advertising Under the Lanham Act.
- Trap. A bad-faith enforcement theory pleaded against a mark owner with a colorable claim invites a fee application in the other direction. Plead it where the statements were actually false or the claim objectively baseless.
[ ] Request fees under 15 U.S.C. § 1117(a) and costs.
[ ] Confirm every factual allegation has a source you can produce, and satisfy Fed. R. Civ. P. 11(b).

Phase 9 — File, serve, and notify the Board

[ ] File and serve promptly. Do not hold service.
- Trap. A declaratory plaintiff who files and waits invites the argument that the complaint was placeholder litigation to freeze a forum, which is the anticipatory characterization by another name.
[ ] File notice of the civil action in any pending Board proceeding and move to suspend.
- Authority. 37 C.F.R. § 2.117(a); TBMP § 510.02. See TTAB Practice Toolkit.
[ ] Decide against a preliminary injunction motion unless the client needs affirmative relief.
- Why. A declaratory plaintiff wants a ruling, not an order, and a denied injunction sets the case's tone. See Moving for a TRO or Preliminary Injunction in a Trademark Case.
[ ] Budget for the infringement counterclaim, which nearly always follows, and plan the case as though the client were a substantive defendant. It is.
[ ] Send a short, factual notice to the affected retailers that the dispute is now in court and that the client stands behind the line.

Phase 10 — Oppose the motions

[ ] Personal jurisdiction. Oppose with the Phase 4 record: enforcement conduct into the forum, sales into the forum, commercial relationships. Request jurisdictional discovery in the alternative.
[ ] Anticipatory filing and transfer. Oppose with the Phase 7 timeline, attaching the correspondence: substantive response, extension, proposal, refusal, impasse, and a filing that did not coincide with the deadline.
[ ] No actual controversy. Oppose with the totality. This rarely succeeds after MedImmune against a genuine demand.
[ ] Discretionary declination. Oppose by showing the declaration will settle the controversy and clarify the parties' legal relations, and by pointing to the cancellation count as substantive relief.
- Authority. Wilton v. Seven Falls Co., 515 U.S. 277, 286-90 (1995); Brillhart v. Excess Insurance Co., 316 U.S. 491, 494-95 (1942).
[ ] Transfer under 28 U.S.C. § 1404(a). Oppose on convenience: where the accused goods are made and sold, where the witnesses are, and the client's forum operations.
[ ] Track which motions the mark owner did not file. A defendant that skips the jurisdictional motion has conceded the point that mattered most.

Phase 11 — Analyze and attack the covenant not to sue

[ ] Read the covenant against the standard: voluntary cessation moots a case only if it is absolutely clear the challenged conduct could not reasonably be expected to recur, and the burden on the party asserting mootness is formidable.
- Authority. Already, LLC v. Nike, Inc., 568 U.S. 85, 91-93 (2013); Friends of the Earth, Inc. v. Laidlaw Environmental Services (TOC), Inc., 528 U.S. 167, 190 (2000).
[ ] Test the covenant against six gaps: is it unconditional; is it irrevocable; does it reach colorable imitations; does it cover the client's customers, distributors, and retailers; does it cover future line extensions and related goods; and does it cover past as well as future conduct?
[ ] Identify a concrete, non-fanciful use the covenant does not reach — a model in development, an adjacent product, a channel expansion — and support it with a declaration.
- Trap. A speculative future use will not save the case. A documented product plan will.
[ ] Preserve the cancellation count by pleading and arguing the registration injury independently: the registration blocks the client's own applications and clouds its rights whether or not the client is sued.
[ ] Preserve any affirmative claims for damages already incurred; a covenant does not moot them.
[ ] Treat the covenant as a settlement signal and negotiate: a broad covenant, consent to the client's pending applications, amendment or partial surrender of the overbroad registration, and a retraction to the retailers.
- Why. A mark owner offering a covenant has decided the fight is not worth it. That is the moment of maximum leverage and it does not come again.

Barrow Field, Phase 11. Kestrel Instruments offers a covenant limited to "binoculars sold under the KESTREL RIDGE mark." Barrow Field's product roadmap shows a KESTREL RIDGE rangefinder in tooling for next season. Counsel declares the gap, keeps the case alive, and uses the eight weeks of motion practice to negotiate a broad covenant plus surrender of the optical-instruments registration.

Phase 12 — Discovery on the four targets that decide it

[ ] Use. Sales by product line and year, first-use documents, specimens, and the evidence behind each declaration of use, for every asserted class.
[ ] Actual confusion or its absence. Customer inquiries, misdirected orders, warranty claims, returns, and internal communications discussing the client. Concurrent sales over a meaningful period are a natural experiment; the mark owner's files show whether it produced anything.
[ ] Enforcement scope. Every demand letter, to whom, on what goods, with what outcome, and the internal decisions behind them.
[ ] The third-party communications. Every version of the customer letter, the distribution list, and the internal discussion of the decision to send it.
[ ] Subpoena the retailers early under Fed. R. Civ. P. 45, while the relationships are current.
[ ] Decide deliberately whether to commission a survey. Budget $60,000 to $180,000 and ask whether the case turns on a factor a survey can move.
- See. Consumer Surveys in Trademark Cases; Trademark Survey Design and Challenge Checklist.
[ ] Watch for a laches or acquiescence record — how long did the mark owner know before it wrote?
- See. Delay Defense Checklist.

Phase 13 — Settle, and get the terms worth having

[ ] Obtain a broad covenant not to sue, or better, a coexistence agreement defining goods, channels, presentation, and territory.
- See. Settling a Trademark Dispute; Trademark Coexistence Agreement — Template.
[ ] Obtain consent to registration of the client's pending applications, drafted with reasons and undertakings rather than as a bare consent.
- Authority. In re E.I. du Pont de Nemours & Co., 476 F.2d 1357, 1361 (C.C.P.A. 1973) (consent as a factor); TMEP § 1207.01(d)(viii).
[ ] Obtain amendment or partial surrender of any overbroad registration identified in Phase 6.
[ ] Obtain a retraction to the retailers in agreed words. This is often the term the client values most and the one the mark owner gives most readily.
[ ] Build in a notice-and-cure mechanism for future conflicts and a mutual release.
[ ] Confirm the agreement addresses assignment, so a later acquirer of either mark is bound.
- Trap. Coexistence agreements that bind only the original parties fail the first time a brand is sold. See Trademark Settlement Checklist.

Phase 14 — Build and file the fee application

[ ] Preserve the Phase 7 response letter as the notice document: it told the mark owner exactly why the claim failed.
[ ] Assemble the exceptional-case record: the objectively baseless assertion; the unused registration knowingly asserted; false statements to customers; refusal to narrow after being shown the defect; and litigation conduct.
- Authority. 15 U.S.C. § 1117(a); Octane Fitness, LLC v. ICON Health & Fitness, Inc., 572 U.S. 545, 554 (2014); Highmark Inc. v. Allcare Health Management System, Inc., 572 U.S. 559 (2014) (abuse-of-discretion review).
[ ] Confirm prevailing-party status, including where the case ended on a covenant that gave the client everything it sought.
[ ] Segregate fees by claim where some counts failed.
[ ] Set the client's expectation honestly: exceptional-case awards remain uncommon, and expert fees are generally not recoverable.
- See. Trademark Integrity Toolkit; What a Trademark Win Is Worth.

The mark owner's five moves, ranked

For counsel on the receiving end of a declaratory complaint, the response sequence is a cost ladder. Work down it.

Move to dismiss for want of personal jurisdiction. Cheapest, most likely to succeed, and dispositive of the forum. If the only forum contact is your letter, file it. Red Wing Shoe; Walden.
Move to transfer or dismiss as anticipatory. Your own letter's deadline is the exhibit — which is why the letter was a forum decision before it was an enforcement decision. § 1404(a); Wilton.
Deliver a covenant not to sue if the forum is bad and the claim is not worth the fight. Make it genuinely broad, or it will not moot anything and you will have given up the claim for nothing.
Counterclaim for infringement if the merits are strong. It restores you to the substantive plaintiff's role and preserves damages. See Pre-Litigation Enforcement Checklist.
Audit your own registrations first. If the complaint pleads cancellation of an unused registration, the exposure outlives this dispute — anyone can petition once the defect is public.

And the prospective lesson. Every element that makes a demand letter more forceful makes the recipient's declaratory action easier: the deadline supplies immediacy, the litigation threat supplies adversity, and copying the recipient's customers supplies both a controversy and personal jurisdiction in their home district, plus a tortious interference count. See Sending an Effective Cease-and-Desist Letter and Trademark Cease-and-Desist Letter — Template.

The five things people get wrong

Filing before answering the forum question. The entire value of going first is the forum. Investigate the mark owner's contacts before drafting a word of the complaint, and be willing to conclude the home district is unavailable.

Filing on the deadline. It converts a legitimate declaratory action into an anticipatory filing in the eyes of the court that will decide the transfer motion. The three weeks of documented negotiation cost less than the motion.

Forgetting the cancellation count. It is the only count a covenant cannot take away, and it is often supported by an audit the mark owner never ran on its own registrations.

Accepting a narrow covenant. A covenant limited to the specific accused product ends the case and leaves the client exposed on everything else. The moment the covenant arrives is the moment of maximum leverage.

Pleading the client's injury instead of the defendant's contacts. Walden closed that door in 2014 and declaratory complaints still walk into it.
