Cross-Border IP Litigation Toolkit: Parallel Proceedings, Section 1782, Evidence, and Recognition

By Casey Scott McKay · 2023-12-19

Intellectual property rights are national and the products they cover are not, so a single commercial dispute becomes several lawsuits in several countries governed by several bodies of law that reach inconsistent results. This toolkit collects what a practitioner needs to run one. It works through forum selection against a stated remedy objective, service and jurisdiction over foreign parties, and the extraterritorial limits the Supreme Court has drawn around patent, trademark, and copyright law. It then addresses the evidence asymmetry that decides many of these disputes, the anti-suit relief that is available only where a contract makes the foreign action a breach, and the coordination discipline that prevents a party contradicting itself across forums. It closes on recognition, where an arbitral award travels and a judgment frequently does not.

Summary. Intellectual property rights are national and the products they cover are not, so a single commercial dispute becomes several lawsuits in several countries reaching inconsistent results. This toolkit works through forum selection against a stated remedy objective, service and jurisdiction over foreign parties, and the extraterritorial limits drawn around patent, trademark, and copyright law. It addresses the evidence asymmetry that decides many of these disputes, the anti-suit relief available only where a contract makes the foreign action a breach, and the coordination discipline that prevents a party contradicting itself across forums — and closes on recognition, where an arbitral award travels and a judgment frequently does not.

Start Here

A patent is a national right. So is a trademark registration, and so, in a more complicated way, is a copyright. Each is granted by a state, enforceable in that state's courts, and subject to that state's rules about validity, scope, and remedy.

The products those rights cover are made in one country, sold in thirty, and shipped through a dozen more.

So the dispute fragments. The patentee sues in two jurisdictions; the accused infringer files a declaratory action somewhere convenient, petitions for post-grant review, and initiates nullity proceedings elsewhere; a further front opens at the border. Each proceeding runs on its own timetable, applies its own law, and produces its own answer, and none waits for the others.

Within that fragmentation the decisive choices are almost never about the merits. They are about which court decides first, what that decision will be worth elsewhere, what evidence can be gathered and from whom, and whether either side can prevent the other from proceeding somewhere it prefers not to be.

Which yields the organising question of this toolkit: what remedy would change the client's commercial position, and which single forum can deliver it? Everything else is execution, and campaigns that begin without that answer file everywhere and achieve nothing.

This toolkit works through mapping and forum, jurisdiction and service, extraterritoriality, evidence, anti-suit relief, coordination, and recognition.

Mapping and Forum Selection

Four maps, and they take a week.

Rights: every registered right by jurisdiction, with status, term, and validity exposure, plus the unregistered rights whose availability varies enormously by country.

Conduct: where the accused product is designed, made, assembled, tested, warehoused, transited, sold, and used — because each act corresponds to a different national right and a different possible remedy.

Parties: every entity in the chain, with jurisdiction of incorporation, assets, affiliates, and any United States presence, which determines both personal jurisdiction and evidence exposure.

Evidence: where the documents and custodians are, and which jurisdictions impose blocking statutes or data transfer restrictions.

Then state the remedy objective in one paragraph, approved by the business. "Sue them everywhere" is not an objective; an injunction covering the market carrying most of the defendant's revenue is.

Match forum to objective. Fast injunctive pressure in Europe, where infringement decisions come quickly and injunctions issue close to automatically on a finding of infringement — very different from the discretionary standard the United States applies after eBay Inc. v. MercExchange, L.L.C., 547 U.S. 388 (2006). Territorial breadth at the Unified Patent Court, with central revocation risk travelling with it. A border remedy at the ITC under 19 U.S.C. § 1337. Damages and discovery in a United States district court, with patent venue confined by 28 U.S.C. § 1400(b). Worldwide licence terms in England, where the courts have accepted the role since Unwired Planet International Ltd. v. Huawei Technologies (UK) Co. Ltd., [2020] UKSC 37. Leverage over supply where the factory sits.

Then sequence: file first where speed creates the pressure, run the damages case in parallel rather than afterwards, and do not file everywhere at once unless the budget genuinely supports the whole campaign.

Service and Jurisdiction

Start with the affiliate. Volkswagenwerk Aktiengesellschaft v. Schlunk, 486 U.S. 694 (1988), holds that the Hague Service Convention does not apply where service can validly be made domestically under state law, so serving a United States subsidiary — where state law permits it — avoids the Convention entirely and saves a year.

Where the Convention applies, plan the timetable around it. Central Authority service in some jurisdictions routinely takes twelve months or more, and a case schedule that assumes otherwise collapses.

Service by mail is available where the destination state has not objected and the forum's law permits it, following Water Splash, Inc. v. Menon, 581 U.S. 254 (2017).

Court-ordered alternative service under Fed. R. Civ. P. 4(f)(3) — email, messaging, or marketplace account — is available where no international agreement prohibits it, and it is the mechanism that made large-scale online enforcement practical.

Do not assume general jurisdiction. Daimler AG v. Bauman, 571 U.S. 117 (2014), and Goodyear Dunlop Tires Operations, S.A. v. Brown, 564 U.S. 915 (2011), confine it to the place of incorporation and the principal place of business.

Plead Fed. R. Civ. P. 4(k)(2) in the alternative for federal claims against a defendant with contacts across the United States but not concentrated in any state. It costs a paragraph, it is the standard route to a foreign manufacturer selling nationally through intermediaries, and it is routinely omitted.

Prepare the forum non conveniens response under Piper Aircraft Co. v. Reyno, 454 U.S. 235 (1981), remembering that a less favourable substantive law in the alternative forum is not itself a reason to retain the case.

And do not plead foreign patent infringement. Voda v. Cordis Corp., 476 F.3d 887 (Fed. Cir. 2007), holds that exercising supplemental jurisdiction over foreign patent claims is an abuse of discretion, and pleading them invites an early motion that costs credibility.

What United States Law Reaches Abroad

The presumption against extraterritoriality does most of the work, and it has been applied to all three principal regimes.

Patent. 35 U.S.C. § 271(a) reaches domestic acts; section 271(f) reaches the supply of components from the United States for combination abroad; and section 271(g) reaches importation of products made abroad by a patented process. The extensions are narrow and have been read narrowly, as Microsoft Corp. v. AT&T Corp., 550 U.S. 437 (2007), demonstrates.

But domestic liability may carry foreign damages. WesternGeco LLC v. ION Geophysical Corp., 585 U.S. 407 (2018), permitted recovery of foreign lost profits caused by a domestic act, because the focus of the damages provision is the domestic infringement rather than where the loss was felt. Domestic conduct, foreign consequences, is the seam through which most cross-border damages arguments now run.

Trademark. Abitron Austria GmbH v. Hetronic International, Inc., 600 U.S. 412 (2023), replaced the divergent circuit tests derived from Steele v. Bulova Watch Co., 344 U.S. 280 (1952), with a focus test: the Lanham Act reaches only infringing uses in commerce that occur domestically.

Copyright. Subafilms, Ltd. v. MGM-Pathe Communications Co., 24 F.3d 1088 (9th Cir. 1994) (en banc), holds that authorising abroad an act of infringement occurring abroad is not actionable here, while the predicate-act doctrine permits recovery of foreign profits where a domestic act of infringement occurred.

Trade secret reaches furthest. 18 U.S.C. § 1837 extends the underlying provisions to conduct outside the United States where the offender is a United States person or entity, or where an act in furtherance occurred domestically — supporting a civil action under 18 U.S.C. § 1836 in circumstances the other regimes would not reach.

And section 337 reaches the goods. 19 U.S.C. § 1337 operates on imported articles without requiring personal jurisdiction over the foreign maker, and it reaches trade secret misappropriation occurring entirely abroad where the resulting imports injure a domestic industry.

Evidence: Section 1782 and Its Limits

28 U.S.C. § 1782 is the most powerful discovery tool in the world, and it is available to foreigners in United States courts.

The statutory requirements are that the target resides or is found in the district, that the material is for use in a proceeding before a foreign or international tribunal, and that the applicant is an interested person. The foreign proceeding need not be pending but must be within reasonable contemplation.

Then the Intel discretionary factors from Intel Corp. v. Advanced Micro Devices, Inc., 542 U.S. 241 (2004): whether the target participates in the foreign proceeding, the receptivity of the foreign tribunal, whether the request circumvents foreign proof-gathering restrictions, and whether it is unduly intrusive or burdensome.

Target non-participants — affiliates, customers, distributors, service providers, banks, logistics providers, testing houses — because the first factor cuts against applications aimed at parties already within the foreign tribunal's reach.

Keep the requests narrow, since breadth is the most common reason a motion to quash succeeds, and support receptivity with a declaration from foreign counsel rather than an assertion.

File early, before the foreign case hardens and positions are fixed. The window is routinely missed by a year.

Note what ZF Automotive closed. ZF Automotive US, Inc. v. Luxshare, Ltd., 596 U.S. 619 (2022), holds that a private commercial arbitration is not a foreign or international tribunal, closing a route that had been used heavily.

Applications are frequently ex parte at the first stage, which is a substantial tactical advantage and a recurring surprise for companies that are not parties to the foreign dispute.

If defending one, attack the statutory elements, the Intel factors, burden, and privilege, and negotiate a protective order under Fed. R. Civ. P. 26(c) confining use to the foreign proceeding.

Blocking Statutes and Data Restrictions

The Hague Evidence Convention is not exclusive. Société Nationale Industrielle Aérospatiale v. United States District Court, 482 U.S. 522 (1987), holds that where the court has personal jurisdiction over a party it may order production under the Federal Rules regardless of the Convention — a holding that has irritated civil law jurisdictions for four decades and that produces genuine conflicts.

Blocking statutes are the response. Several jurisdictions criminalise production of evidence for foreign proceedings outside treaty channels, and the comity analysis courts apply weighs the importance of the documents, the specificity of the request, the origin of the information, the availability of alternatives, and the competing state interests — and frequently orders production anyway.

Data protection is the sharper edge. Comprehensive regimes condition recognition of foreign orders requiring transfer of personal data on an international agreement and restrict transfers generally, so a production order covering employee communications from a foreign entity engages both.

Raise the conflict early and specifically, with a declaration of foreign law rather than an assertion, and propose a staged approach: unproblematic material first, a treaty request for the remainder, argument on what is left.

Minimise and anonymise personal data, and document the minimisation.

Negotiate a protective order that addresses the foreign regulator's proportionality concerns, not merely the opponent's confidentiality concerns.

And expect to be on both sides. A client that welcomes an application against its opponent's affiliate will resent the equivalent against its own, and the positions taken in one proceeding will be quoted in the other.

Anti-Suit Relief

A United States court cannot enjoin a foreign court. It can, where it has personal jurisdiction, enjoin a party before it from prosecuting a foreign action — achieving the same result while preserving the fiction that no disrespect is intended.

Ask first whether a contract makes the foreign action a breach. A forum selection clause, an exclusive licence, a covenant not to sue, or a FRAND undertaking converts the application from an assault on comity into the enforcement of a promise, and Microsoft Corp. v. Motorola, Inc., 696 F.3d 872 (9th Cir. 2012), is the model.

Then check the circuit. The permissive approach of Gallo v. Andina Licores S.A., 446 F.3d 984 (9th Cir. 2006), treats comity as one factor; the restrictive approach of China Trade & Development Corp. v. M.V. Choong Yong, 837 F.2d 33 (2d Cir. 1988), requires a threat to the court's jurisdiction or an important public policy and rarely produces relief. Laker Airways Ltd. v. Sabena, Belgian World Airlines, 731 F.2d 909 (D.C. Cir. 1984), remains the fullest judicial treatment of duelling injunctions.

Establish the threshold elements in either circuit: same parties, same issues, and a domestic proceeding dispositive of the foreign one.

Expect escalation. Anti-anti-suit injunctions are now routine in standard-essential disputes, and at least one dispute has produced a third order in the sequence — the point at which the system has stopped functioning as a system.

And weigh the signal. An anti-suit application is read by opponents and courts alike as an admission that the applicant expects to lose abroad, and where the merits are strong the better course is to litigate them.

Coordination Across Forums

The most common self-inflicted wound in this practice is inconsistency, and nobody owns it by default.

Appoint a consistency coordinator with authority to hold any filing in any jurisdiction.

Maintain a consistency register listing every substantive position taken anywhere: claim scope, the state of the art, dates of first use, inventorship, valuation, and the reason a licence was or was not taken.

Circulate every draft filing to every team before it issues, because a broad infringement theory advanced in one forum reappears in a validity proceeding in another within days.

Coordinate expert positions centrally, since experts retained separately in each jurisdiction will contradict each other on the state of the art unless someone owns the question.

Reconcile valuation across litigation, tax, and licensing. A royalty rate in a damages report, a transfer price in a tax filing, and a figure in a negotiation are all discoverable and all comparable.

Map privilege by jurisdiction, noting that in-house and patent attorney communications are protected in some systems and not others, and route sensitive analysis accordingly.

Instruct local counsel with the campaign context, not the national question, because counsel optimising locally will make choices that are correct there and damaging globally.

Impose a single reporting format across all firms, and ask each the same five questions at the outset: time to first-instance decision, availability and speed of preliminary relief, whether validity is heard with infringement, cost through judgment, and what the losing party pays.

And agree the escalation route and time zones, because a foreign court will list a hearing on three weeks' notice and someone must be able to instruct overnight.

Recognition and Enforcement

A United States judgment abroad is recognised according to the law of the enforcing state, and civil law jurisdictions frequently refuse punitive and multiplied components — so a judgment including enhanced damages under 35 U.S.C. § 284 may be enforceable in part and refused in part.

A foreign money judgment here is recognised under state law, most commonly a version of the uniform recognition act, with narrow grounds of refusal: no impartial tribunal, no jurisdiction, fraud, and repugnance to public policy.

Foreign injunctions and non-money judgments rest on comity rather than statute, and enforcement is discretionary and inconsistent.

Public policy has teeth at the edges. 28 U.S.C. § 4102 bars recognition of foreign defamation judgments inconsistent with the First Amendment, and analogous arguments arise where a foreign order would compel conduct that domestic law protects.

Arbitral awards travel. Under the New York Convention, implemented at 9 U.S.C. § 201, the grounds for refusal are few, uniform, and narrowly construed, and enforcement is available in more than one hundred and seventy states. This asymmetry is the strongest practical argument for arbitration in any cross-border intellectual property relationship, and it should be made at the contracting stage rather than at the dispute stage.

Asset location decides everything. A judgment or award is worth what can be collected, and the collection jurisdiction should be identified during the party mapping rather than discovered after judgment.

And plan post-judgment discovery abroad, which is itself a section 1782 use case and one courts have been receptive to.

Settlement

A settlement that resolves one proceeding is not a settlement.

Cover every forum by name, with an obligation to withdraw or discontinue each within a stated period and the costs position for each specified.

Cover every entity — parent, subsidiaries, affiliates, distributors, customers, and contract manufacturers on both sides — because a release omitting customers leaves the patentee free to sue them, which is precisely why implementers insist on customer coverage.

Cover every right, including continuations and divisionals from the same priority, or the dispute reappears with a different number.

Make it worldwide and say so, because a territorially limited release invites the same dispute in the next market.

Use an arbitration clause for the settlement agreement itself, seated in a New York Convention state, so that a breach produces an award enforceable wherever either party holds assets.

Record the tax and transfer pricing treatment of any payment, consistently across jurisdictions, because a lump sum characterised inconsistently creates a second dispute with two revenue authorities.

And time it against the campaign. The most productive settlement windows are immediately after the fast forum's first-instance decision and immediately after any appellate mandate, because those are the moments when the dispute has been repriced for both sides.

Defending a Multi-Front Campaign

The defendant's problem is different, and the instinct to fight everywhere is usually wrong.

Identify the one front that actually threatens the business — almost always the fast injunction jurisdiction covering a major market, or the border remedy — and resource it properly while running the others defensively.

Attack validity everywhere it is cheap. Post-grant review under 35 U.S.C. § 311, opposition, and national nullity proceedings each put the same right at risk at a fraction of the cost of an infringement defence, and a revocation ends every proceeding at once. Watch the one-year bar from service and the estoppel consequences under 35 U.S.C. § 315(e), which are the most commonly missed deadlines in defensive practice.

Start the design-around immediately, because a non-infringing alternative available in six months changes the settlement value of every proceeding at a fraction of the legal cost.

Test standing and title. Unrecorded assignments, missing inventor assignments, and co-owner joinder defects are common in portfolios that have moved between entities and are dispositive where they exist.

Consider filing a declaratory action first where the demand letter supports jurisdiction under MedImmune, Inc. v. Genentech, Inc., 549 U.S. 118 (2007) — and note the mirror point for patentees, which is that a letter specific enough to be useful is specific enough to be sued on.

Watch customer suits, which create indemnity obligations and commercial pressure disproportionate to the merits.

Check whether a protective brief is available in jurisdictions that permit them, to prevent ex parte preliminary relief.

And price settlement honestly at the outset, because a defendant that spends three years and then takes the month-two licence has bought only delay.

Governance and Budget

Budget by front, decide by total. A five-front campaign approved incrementally is how businesses spend several times what they would have authorised as a single decision.

Write the stop rule before filing: which outcomes — a revocation, an adverse construction, a refused injunction, a spend threshold — trigger re-evaluation, and what happens then.

Check insurance early, because advertising injury coverage responds to some trademark and copyright claims, rarely to patent claims, and narrowly to foreign proceedings.

Report the campaign, not the cases. A single tracker showing every forum, every next milestone, every spend commitment, and what each proceeding can and cannot deliver is what allows a board to approve a campaign; a series of separate requests produces refusal at front three.

Set the timetable expectation. Three to five years across all fronts is ordinary, and a client told this at the outset makes better decisions at every subsequent branch.

And appoint one owner. The most useful person on a multinational dispute is frequently not the best advocate in any forum, but the one who holds the maps, keeps the consistency register, guards the budget, and can say in a sentence what the campaign is for.

Prevention

Put an arbitration clause in every cross-border agreement, seated in a New York Convention state, with an institution named, express provision for interim and emergency relief, a confidentiality obligation, and a governing law checked for enforceability of the ownership and confidentiality terms.

Register the marks in the manufacturing jurisdiction, whether or not the client sells there, because in a first-to-file system a supplier, distributor, or broker can register the mark and block the client's own goods at export.

Record rights with customs in every significant market under provisions such as 19 U.S.C. § 1526, which is inexpensive and is the precondition to seizure.

Keep the national filing programme current, because a dispute cannot be fought in a market where no right was ever obtained.

Decide the Unified Patent Court opt-out position deliberately, at portfolio level, with the litigation strategy in view.

And for the smaller dispute, escalate deliberately. Most cross-border problems arrive at a business that cannot fund five proceedings and would not benefit from them: identify the single market where the loss is occurring, use customs recordation and platform takedown, register in the manufacturing jurisdiction, and put contractual dispute mechanisms into every distribution agreement. The escalation to parallel litigation should be one decision with a modelled budget, not the accumulated result of five reactions to five provocations — which is how most businesses arrive there, and the most expensive way to do so.

A Closing Note

The uncomfortable truth about cross-border intellectual property litigation is that it is only partly a legal exercise.

The doctrines are real — extraterritoriality, comity, jurisdiction, recognition — and they matter at the edges. But the decisive variables are the speed of the chosen forum, the location of manufacturing, the reach of a border remedy, the asymmetry of the evidence tools, and the depth of each side's budget.

A patentee with a mediocre right, a filing in a fast jurisdiction, and a defendant whose only assembly plant sits inside that territory is in a stronger position than a patentee with an excellent right and nothing but a domestic damages case. That is not how the system is supposed to work, and it is how it does work.

Which reorders the first conversation. Before assessing infringement, ask where the goods are made, where they are sold, where the defendant's assets are, and what remedy would change the client's commercial position. The answer usually identifies one or two forums out of five, and the case that follows is dramatically cheaper and more likely to succeed than the one that begins with a complaint filed where the client happens to be.

The Forums, Briefly Characterised

Germany. Fast infringement decisions, bifurcated validity, and an injunction that issues on a finding of infringement without an equitable discretion analogous to eBay. A proportionality provision has been added and has so far changed very little. For a patentee with a strong right and a defendant selling into Europe, this is the pressure point.

The Unified Patent Court. A single action covering participating member states, an aggressive timetable, and a central division that can revoke across the whole territory. Its arrival created a genuine strategic choice — breadth with concentrated risk, or national actions with fragmented risk — and the opt-out decision is now a portfolio-level question.

The United Kingdom. Slower and more expensive at first instance, with sophisticated technical judges, full validity determination alongside infringement, and a demonstrated willingness to set worldwide licence terms.

The Netherlands. Procedurally inventive, historically the home of cross-border relief, and a common venue for preliminary relief affecting European distribution.

China. Fast, increasingly technically competent, with substantial damages in some sectors, active anti-suit practice, and decisive leverage where manufacturing is located there.

The United States. Slow, expensive, discovery-heavy, with jury trials, enhanced damages, and a discretionary injunction standard. Its comparative advantages are discovery, damages, and the ITC.

The ITC. Roughly sixteen months to an exclusion order, no damages, a domestic industry requirement, and in rem relief reaching goods rather than parties — with the parallel district court action stayable at the respondent's election under 28 U.S.C. § 1659.

Choosing among them is the strategy. Everything else is execution.

Running the ITC Front

The ITC deserves separate treatment, because its procedure resembles nothing else and because it is the most effective remedy against a foreign manufacturer.

The threshold is domestic industry. Significant investment in plant and equipment, significant employment of labour or capital, or substantial investment in engineering, research and development, or licensing relating to protected articles — assembled before filing rather than during the investigation.

The pace is unforgiving. A target date within weeks, discovery in months, and an evidentiary hearing before an administrative law judge within roughly nine months. A respondent that spends the first thirty days seeking an extension is behind for the entire investigation.

The remedies are in rem. A limited exclusion order against the named respondents; a general exclusion order where circumvention is likely and the source is hard to identify; and cease and desist orders reaching domestic inventory. There are no damages.

Presidential review runs for a defined period, after which Customs enforcement operates on its own logic — so a complainant's practical result depends on an enforcement relationship built during the investigation rather than after it.

And the ITC is a trade secret forum too, reaching misappropriation occurring entirely abroad where the resulting imports injure a domestic industry, which no district court can do.

For a respondent, the priorities are the domestic industry challenge, the design-around, and the redesign ruling process — because an exclusion order that a modified product does not fall within is an exclusion order the business can live with.

The Race, and What Winning It Buys

Speed differs enormously by forum, and a judgment obtained first has effects out of proportion to its formal reach.

It cannot bind a foreign court on the validity of a foreign right, and it settles the commercial reality: an injunction in a major market forces a redesign or a licence, and once either happens the other proceedings lose their purpose.

Which is why practitioners describe cross-border intellectual property litigation as a race to judgment. That is the actual incentive structure, not a metaphor.

Declaratory actions are the defensive counterpart. A potential defendant that expects to be sued files first in a forum it prefers, and the standard after MedImmune makes an aggressive licensing letter a jurisdictional risk for the sender.

In Europe the equivalent manoeuvre was the torpedo — a declaratory claim filed in a slow jurisdiction to freeze proceedings elsewhere under the lis pendens rules. Recast regulation and the Unified Patent Court have blunted it, but the underlying logic recurs in every system that gives priority to the first-seised court.

Protective briefs are available in some jurisdictions to prevent ex parte preliminary relief, and a patentee planning a surprise application should check whether one is on file.

And the sequencing rule holds at every scale. Whoever obtains an enforceable remedy in a market that matters, first, sets the terms of everything that follows — which is why the forum decision deserves more attention than the merits assessment that usually consumes it.

What Clients Actually Ask

"Can we get one worldwide ruling?" Not for registered rights, which are national and must be enforced where granted. The exceptions are a worldwide licence rate set by a court both parties are before, and an arbitral award, which travels under the New York Convention.

"Why can't we sue them here for what they do abroad?" Because Abitron confines the Lanham Act to domestic use in commerce, Subafilms confines copyright liability to domestic acts, and section 271 reaches domestic acts with narrow statutory extensions. Foreign damages from a domestic act are a different and available point.

"How do we get their documents?" Section 1782 against their United States affiliates, customers, and service providers — a tool their home system does not offer them and frequently does not offer against them.

"Can they get ours?" Yes, symmetrically, and the client should be told before the first application rather than after the reciprocal one arrives.

"Can we stop their foreign case?" Only by enjoining the party, only where the court has jurisdiction over it, and realistically only where a contract makes the foreign suit a breach.

"What will this cost?" More than any single-forum estimate suggests, because coordination, foreign law evidence, and consistency work are real workstreams that appear in no national budget.

"How long?" Three to five years across all fronts, and a client told this in week one makes better decisions at every branch than one told it in year two.

The Client's Experience

It is bewildering, and the bewilderment has consequences. A general counsel accustomed to a single lawsuit with a single outcome is asked to fund five proceedings producing five answers on different dates, some inconsistent, none conclusive on its own.

The reporting has to be built differently, as a campaign tracker rather than a set of case updates — because boards approve campaigns they can see the shape of and refuse each new front that arrives as a separate request.

Settlement has to be global or it is not settlement, as set out above.

Insurance rarely helps, and the policy should be checked early rather than assumed.

And the timetable is long. A client told at the outset that this is a campaign rather than a case makes better decisions at every subsequent branch — which is the single most useful thing a practitioner communicates in this practice, and the one most often left unsaid because it makes the first conversation harder.

Making it easier is not the objective; making it accurate is, and a client who understands the shape of what they are funding is a client who funds it properly or declines it early.

Forms and Templates

The License Agreement Template supplies the structure for the cross-border agreements that generate most of these disputes and that can prevent them: an arbitration clause seated in a New York Convention state, with an institution named, express interim and emergency relief, confidentiality, and a governing law checked for enforceability where the counterparty sits. The Cease and Desist Template requires particular care in this context, because after MedImmune a letter specific enough to be commercially useful is specific enough to support a declaratory action in a forum of the recipient's choosing. The Portfolio Inventory Template adapts into the four maps this toolkit treats as foundational — rights, conduct, parties, and evidence. Beyond those, maintain five documents: a remedy statement approved by the business; a forum decision memorandum recording the rejected alternatives; a campaign budget by front with a stop rule; a consistency register covering every position in every forum; and a foreign law evidence file on blocking statutes and data restrictions prepared before any production order is sought.
