Negotiating and Litigating a FRAND License: A Practical Guide

Document type: Guide Practice area: Intellectual Property — Patents Jurisdiction: United States, with international context Last reviewed: 5 September 2026

Almost every standard-essential patent dispute ends in a portfolio license at a negotiated rate. What the litigation determines is the leverage, and the leverage is determined mostly by conduct — who gave real notice, who responded, who made a supported offer, and who has been behaving reasonably.

That makes this an unusual practice. The doctrinal questions are genuinely unsettled and the answers differ by jurisdiction. The operational questions are not: both sides know what a reasonable party does, and the party that does it wins the framing.

This guide walks that conduct, from both sides.

PART ONE — THE IMPLEMENTER, BEFORE ANY LETTER

Step 1: Map your standards exposure

Most companies cannot answer basic questions about their own exposure. Answer them before someone else asks.

Which standards do our products implement? Cellular, Wi-Fi, video codecs, Bluetooth, NFC, positioning, audio codecs — and which releases or versions.
At what level? Do we implement the standard ourselves, or does a purchased component?
Which products, in what volumes, at what prices? This is the base for any royalty calculation and you will need it.
Which functionality is optional versus mandatory in the standards we implement? Optional features we do not use cannot support essentiality.
What have we already paid? Existing SEP licenses, pool licenses, and any royalties embedded in component prices.

Why this matters. An implementer that receives a demand letter and spends four months determining which standards its products implement has already lost four months of the willingness clock.

Step 2: Analyze the supply chain

This is frequently dispositive and it is frequently skipped.

For each standardized function, identify the component that implements it and its supplier.
Ask each supplier, in writing, whether it is licensed for the relevant standards, by whom, and for what scope.
Obtain the license terms if you can — many suppliers will confirm coverage without producing the agreement.
Analyze exhaustion. A licensed component sold by the licensee may exhaust the patent as to downstream use, but only if the license covers the products, the field of use, and the downstream activity. Read it.
Check your supply agreements for IP indemnities, and read the exclusions. Many standard indemnities carve out patents essential to standards — which is precisely the exposure you need covered.
Where indemnities exist, understand the notice and tender obligations and comply with them promptly.

The result. Some implementers discover they are substantially covered through their supply chain, which converts a $4 million demand into a coverage discussion. Others discover their indemnity excludes exactly this exposure — which is worth knowing before the negotiation rather than during it.

Step 3: Budget and govern

Model SEP royalties as a cost of implementing the standard, not as a litigation contingency.
Assign an owner: someone in legal or licensing who holds the relationship, tracks demands, and maintains the exposure map.
Establish a response protocol — who is notified when a letter arrives, and what happens in the first three weeks.
Identify counsel with SEP experience before you need them.

PART TWO — THE FIRST NINETY DAYS

Step 4: Respond within three weeks, and state willingness

This is the single highest-value action available to an implementer, and it commits you to nothing about the rate.

What the response should contain:

A statement of willingness to take a license on FRAND terms. In terms.
A request for claim charts for representative patents, mapped to specific sections of the standard.
A request for the essentiality basis — which sections, mandatory or optional.
A request for the rate basis and any comparable licenses relied on.
An offer to enter a confidentiality agreement so comparables can be produced. Attach a draft.
A question about the licensing level — does the patent holder license at the component level, and is our supplier licensed?
A named contact and a commitment to engage on a defined schedule.

What the response should not contain:

A general denial of infringement without analysis.
A refusal to discuss until the patent holder proves infringement of every patent.
Silence.
A demand that the patent holder sue.

Why. Every framework for assessing willingness starts here. An implementer that responds promptly, states willingness, and asks the right questions has made an unwillingness finding very difficult, and that removes the patent holder's principal leverage.

Step 5: Do the essentiality work

This is where the money is, and it takes months.

Obtain the charts and the patent list.
For each charted patent, map the claim element by element to the specific standard section cited.
For each mapped section, determine: is it mandatory or optional? Do we implement it?
Determine whether the claim requires more than the standard requires — if so, practicing the standard does not necessarily infringe.
Assess validity for the patents that survive the essentiality screen.
Extrapolate to the portfolio. If three of eight charted patents are arguably essential, that is evidence about the whole declared portfolio — and the charted patents are presumably the patent holder's best.
Document the analysis; it is the foundation of your counter-offer and your top-down denominator.

Budget realistically. A serious essentiality analysis of a substantial portfolio is a six-figure exercise. It is also the only quantitative input you will have.

Step 6: Build the valuation

Two methodologies, and you should run both.

Comparable licenses:

Identify publicly reported licenses to this portfolio or comparable portfolios.
Obtain the patent holder's licenses under the confidentiality agreement.
For each, normalize: portfolio scope, field, term, geography, cash versus cross-license, lump-sum versus running rate, litigation context.
Identify similarly situated licensees and any rate differences — this is the non-discrimination argument.

Top-down:

Establish an aggregate royalty burden for the standard, from public statements by SSO participants, industry studies, and the product's economics.
Establish the denominator: how many patents are genuinely essential, adjusted from declared counts using your essentiality work.
Establish the numerator: the patent holder's genuinely essential count.
Compute the share and adjust for relative technical importance.

Reconcile them. A counter-offer supported by two methods that produce similar numbers is far more persuasive than one supported by whichever method produces the lower figure.

Apportionment:

Identify the smallest salable patent-practicing unit and its price.
Be prepared to express your offer at either base with an equivalent rate, so the base argument does not obscure the number.

Step 7: Make the counter-offer

In writing, with a specific rate and structure.
With the methodology stated and the supporting analysis attached or summarized.
Addressing the patent holder's rate basis directly — why the comparables it cites are not comparable, or why the base is wrong.
With a proposed term, scope, and geography.
Promptly after receiving the information you requested.

Do not offer zero or a nominal amount without justification. That is the counter-offer that establishes unwillingness.

Step 8: Provide security

If you continue selling while disputing:

Establish an escrow, a letter of credit, or a bond in the amount of your own offer for the disputed period.
Tell the patent holder, in writing.
Render an account of past use if the framework requires it.

Why. This is the strongest available evidence of good faith, it is inexpensive relative to the exposure, and it makes an injunction or exclusion order substantially harder to obtain anywhere.

PART THREE — THE PATENT HOLDER

Step 9: Prepare before asserting

Do your own essentiality analysis first. Asserting a declared portfolio without knowing what is actually essential produces a position the implementer will dismantle, and it is the most common patent-holder error.

Select representative patents across the portfolio, not just the ones prosecution liked.
Chart them element by element to specific standard sections.
Confirm each section is mandatory, not optional.
Confirm the claim does not require more than the standard requires.
Assess validity honestly — the implementer will.
Estimate the genuinely essential proportion of the portfolio. You will be asked.

Build the rate basis:

Assemble your comparable licenses and normalize them.
Prepare a top-down cross-check.
State your apportionment reasoning explicitly.
Audit your own license history for discrimination exposure. Different rates to similarly situated licensees is the "ND" problem, it is discoverable, and it is the argument you cannot answer after the fact.

Settle your licensing level position:

Device or component, and be consistent with your existing licenses.
Determine whether the target's suppliers are already licensed and what that does to your claim.

Step 10: Give real notice

Identify the standard, the release, and the specific patents.
Provide claim charts for representative patents, mapped to standard sections.
State the essentiality basis.
State a specific rate and the basis for it.
Offer a confidentiality agreement so comparables can be shared. Attach a draft.
Propose a schedule for engagement.
Name a contact with authority.

A letter without charts and without a rate explanation starts the negotiation behind, and it is the fact an implementer's counsel will quote in every subsequent filing.

Step 11: Negotiate in a way the record will support

Respond to counter-offers substantively and promptly. Silence over months is evidence.
Enter the confidentiality agreement without unreasonable conditions.
Explain why the implementer's methodology is wrong, with analysis rather than assertion.
Move when the implementer moves. A patent holder that never adjusts its opening number looks unreasonable.
Document every step: what was sent, when, what was received, and what response was made.

Do not seek an injunction against a demonstrably willing licensee. It rarely works in United States district courts after eBay Inc. v. MercExchange, L.L.C., 547 U.S. 388 (2006), it creates antitrust exposure, and it damages the negotiation posture in every forum.

PART FOUR — WHEN IT GOES TO LITIGATION

Step 12: Choose the forum, understanding what each can do

United States district court. Damages, a declaration of FRAND terms, and breach of contract claims. Injunctions rare. Can potentially set terms for a portfolio.

The ITC. Exclusion orders and cease-and-desist orders, on a statutory schedule, applying public interest factors rather than eBay. No damages. The forum a patent holder chooses when it wants leverage, and the forum where public interest submissions matter most.

Foreign courts. Injunctions more readily available in some jurisdictions; some willing to set global rates. Different frameworks for assessing willingness.

Arbitration. Increasingly proposed, particularly by implementers, because it produces a rate without an injunction and can be global. A patent holder's refusal to arbitrate is sometimes offered as evidence of unwillingness; so is an implementer's.

The decisions that follow from forum choice:

Filing sequence matters enormously. The first filing frequently determines which court sets the terms.
Assess anti-suit exposure before filing anywhere. A filing in one jurisdiction can draw an anti-suit injunction from another, and an anti-anti-suit injunction after that.
Coordinate positions across jurisdictions from day one. Everything filed in one forum is an exhibit in the others.
Consider whether you can live with a global determination — and recognize that refusing one may itself be characterized as unwillingness.

Step 13: Build the rate-setting record

Whether the tribunal is a court or an arbitral panel, the evidence is the same.

Comparable licenses:

Obtain the patent holder's full license portfolio in discovery.
Normalize each: scope, field, term, geography, structure, cash versus cross, litigation context, volume assumptions.
Identify the genuinely comparable subset and explain the exclusions.
Develop the discrimination argument if similarly situated licensees paid materially different rates.

Top-down:

Aggregate royalty burden, with sources.
Essentiality-adjusted denominator, with the methodology and sample.
Numerator, on the same methodology.
Relative value adjustment, if any, with a basis.

Apportionment:

Identify the smallest salable patent-practicing unit and its price.
Address the entire market value rule if a device-level base is used.
Be prepared to express the same number at either base.

Experts:

A technical expert on essentiality — this is a distinct skill from ordinary infringement work.
An economist on the rate, the base, and stacking.
A licensing expert on industry practice and how comparables should be read.
Confirm all three are consistent with each other and with the positions taken in other forums.

Step 14: Handle the ITC differently

Recognize the schedule: an investigation moves to a target date on a statutory timetable, and the Commission does not stay for a parallel case or an IPR.
Public interest is the SEP battleground here. Prepare submissions addressing the effect of an exclusion order on public health and welfare, competitive conditions, production of like articles, and consumers.
Develop the willingness record as the central public interest fact — an implementer that has engaged, offered, and provided security has a powerful submission.
Consider a domestic industry challenge; a licensing-based domestic industry has its own requirements.
Plan for the Presidential review period.
Assess a bond during that period if an order issues.

PART FIVE — A WORKED NEGOTIATION

Thorncroft Wireless and Marchbank Devices, on the facts from the companion article: 1,200 declared-essential families, 4 million industrial sensors a year at $85, with a $9 cellular module.

Month 0 — the demand. 1.2 percent of device price, about $3.6 million a year. No charts, no patent list, no rate explanation.

Month 0, week 3 — Marchbank's response. Ndidi Vasquez-Thornbury's letter states willingness, requests charts and essentiality basis, requests the rate basis and comparables, attaches a draft confidentiality agreement, and asks whether Thorncroft licenses at the module level and whether Marchbank's supplier is licensed.

Weeks 3–8 — the supply chain analysis. Marchbank asks its module supplier in writing. The supplier confirms a license from three SEP holders, not including Thorncroft. The indemnity in the supply agreement excludes patents essential to standards — a discovery Marchbank makes now rather than in month eighteen, and which changes its budget.

Month 3 — charts arrive. Eight patents.

Months 3–8 — the essentiality work. $280,000 and five months. The result: three arguably essential, two mapped to optional features Marchbank does not implement, two do not read on the standard as written, one likely invalid. Extrapolated essentiality: 20 to 30 percent of the declared portfolio.

Month 8 — the counter-offer. $0.11 per unit, supported by a top-down analysis with an essentiality-adjusted denominator, a comparables analysis from two publicly reported licenses, and an apportionment argument that the standardized functionality resides in the $9 module.

Month 10 — escrow. Marchbank places $1.1 million in escrow representing its offer for the disputed period, and tells Thorncroft in writing. Ndidi's note to the file: "This is the cheapest insurance available. It costs us the time value of $1.1 million and it removes the exclusion order."

Month 12 — Marchbank proposes binding arbitration of the rate, globally. Thorncroft declines.

Month 16 — Thorncroft files at the ITC and in the District of Delaware. Marchbank counterclaims for breach of the FRAND commitment and seeks a rate determination.

Months 16–22 — the ITC public interest fight. Marchbank's submission is built entirely from the record it created: the three-week response, the confidentiality agreement it offered, the essentiality analysis it performed, the supported counter-offer, and the escrow. Thorncroft's opening letter — no charts, no rate basis — is Exhibit A.

Month 22 — settlement. $0.19 per unit, five-year term, release for past sales, most-favored-licensee provision.

Costs: Marchbank about $3.1 million in fees and analysis; Thorncroft about $2.8 million. Against a first-year gap of $3.16 million between the demand and the offer.

What produced the result:

The three-week response. Free, and it made unwillingness unavailable as a theory.

The essentiality work. $280,000, and it was the only quantitative analysis anyone had.

The escrow. $1.1 million of working capital, and it neutralized the ITC.

Thorncroft's opening letter. A demand without charts or a rate basis, quoted against it for two years.

PART SIX — SETTLEMENT STRUCTURE

Almost every dispute ends here, and the terms are more numerous than the rate.

Step 15: Negotiate the whole package

The rate and structure:

Running royalty per unit, ad valorem percentage, or lump sum.
The base, stated explicitly.
Tiering or volume discounts.
Caps and floors.
Currency and payment timing.

Scope:

Which patents — the asserted portfolio, all SEPs for the standard, all SEPs for all standards, or the whole portfolio.
Which standards and releases, including future releases.
Which products, defined by category rather than by model number so the license survives product changes.
Geography — a global license is usually what both sides need.
Have-made rights and coverage of contract manufacturers.
Affiliate coverage, and what happens on acquisition.
Downstream coverage — does the license extend to customers, and does it exhaust?

Term and release:

Term, and what happens at expiry.
Release for past sales, with the period stated.
Covenant not to sue on unlicensed patents for the same functionality.

Protective terms for the licensee:

Most-favored-licensee, with the comparison methodology defined.
Adjustment if the portfolio shrinks materially — patents expire, are invalidated, or are sold.
Transferee obligations: if the patent holder sells patents, the buyer takes subject to the license.
Audit rights that are reasonable in scope and frequency.
Confidentiality, with carve-outs for disclosure to auditors and in litigation.

Protective terms for the patent holder:

Reporting obligations and audit rights.
Late payment interest.
Termination for material breach, with cure.
No challenge to essentiality, or a defined consequence if the licensee challenges validity.

Dispute resolution:

Arbitration of rate adjustments and audit disputes.
Governing law — and note the SSO policy's own choice of law may matter.

Step 16: Address the pool question

Is there a pool for this standard, and is the patent holder a contributor?
If yes, does a pool license cover this portfolio? Check the contributor list; the most common misunderstanding about pools is assuming coverage.
If the patent holder is outside the pool, the pool rate is a comparable for the bilateral negotiation — a useful one, because it is published and market-tested.
For an implementer, taking the pool license is usually the right first step: it is cheaper than bilateral negotiation, it establishes a benchmark, and it is evidence of willingness.

PART SEVEN — BUDGET, STAFFING, AND MISTAKES

Budget

Item	Implementer	Patent holder
Exposure mapping and supply chain analysis	$50K–$200K	—
Essentiality analysis (substantial portfolio)	$200K–$800K	$300K–$1M
Comparables and valuation work	$150K–$500K	$150K–$500K
Negotiation counsel through 12 months	$200K–$600K	$200K–$600K
District court rate-setting case	$3M–$10M	$3M–$10M
ITC investigation	$4M–$12M	$4M–$12M
Foreign proceedings, per jurisdiction	$1M–$5M	$1M–$5M
Anti-suit / anti-anti-suit motion practice	$500K–$2M	$500K–$2M

The best-value line items are the exposure mapping and the essentiality analysis. Both are a fraction of the litigation cost and both change the number.

Staffing

Implementer: a licensing owner who holds the relationship; a technical team that can do essentiality mapping; SEP counsel; an economist for the valuation; and someone who owns the escrow and security decision.

Patent holder: a portfolio analyst who can produce charts and an honest essentiality estimate; a licensing executive with authority; counsel experienced in the ITC and in the relevant foreign forums; and an economist.

Both: one person accountable for cross-jurisdictional consistency, because everything filed anywhere is an exhibit everywhere.

Mistakes that decide leverage

Implementer: not responding for months. The single most damaging thing an implementer can do.

Implementer: a general denial without analysis. Reads as unwillingness.

Implementer: refusing a confidentiality agreement. It prevents you from seeing the comparables and it looks obstructive.

Implementer: offering zero. A counter-offer without justification is evidence of unwillingness.

Implementer: continuing to sell with no security. Escrow is cheap and it neutralizes the strongest remedy.

Implementer: not checking the supply chain. Sometimes the answer is that you are already covered.

Implementer: not reading the indemnity's SEP carve-out until month eighteen.

Patent holder: a demand letter with no charts and no rate basis. It is quoted against you for the life of the dispute.

Patent holder: asserting a declared portfolio without an essentiality analysis. The implementer will do it and you will be answering their numbers.

Patent holder: never moving off the opening number. It makes you the unreasonable party.

Patent holder: seeking an injunction against a demonstrably willing licensee. It rarely works and it creates antitrust exposure.

Patent holder: ignoring your own license history. Discrimination exposure is discoverable and unanswerable after the fact.

Both: inconsistent positions across jurisdictions. The most avoidable failure in a multi-forum dispute.

PART EIGHT — THE MULTI-JURISDICTIONAL RACE

Major SEP disputes are now fought on three continents at once, and the procedural moves are a substantive part of the outcome.

Step 17: Map the forums before anyone files

For each candidate jurisdiction, determine:

What relief is available — injunction, damages, rate determination, exclusion order.
How fast. Speed is leverage.
What framework applies for assessing willingness.
Whether the court will set global terms, and whether refusing a global determination there would be held against your client.
Anti-suit exposure — could filing here draw an injunction from elsewhere, and could we obtain one?
Where the products are sold and manufactured, which determines where an injunction actually hurts.

Step 18: Understand the sequence

The pattern that recurs:

Patent holder files for an injunction in a fast, injunction-friendly jurisdiction.
Implementer files for a global rate determination elsewhere.
Implementer seeks an anti-suit injunction ordering the patent holder not to pursue the first action.
Patent holder seeks an anti-anti-suit injunction in the first jurisdiction.
Additional filings follow in third countries.
The parties settle, because the position has become unmanageable for both.

What this means operationally:

Filing first is a real advantage and it is decided in weeks, not months.
Prepare the whole sequence before step 1. A party that files without having modeled the response is reacting for the rest of the dispute.
Anti-suit motions are expensive and fast. Have counsel in each jurisdiction engaged before you need them.
Everything you file anywhere is evidence everywhere, including statements about willingness, rates, and portfolio scope.

Step 19: Consider arbitration seriously

Binding arbitration of the rate — global, with a defined methodology — resolves most of what the litigation is about.

Why implementers propose it: it produces a rate without an injunction, it is global, and it is faster.

Why patent holders resist it: it removes the injunction leverage that produces settlements.

Why it is worth proposing anyway, from either side: a refusal to arbitrate is increasingly offered as evidence of unwillingness, and a party that proposes it has made a record. The offer costs nothing and it is frequently the fact that moves a negotiation.

If you agree to arbitrate, settle these terms:

Scope: which patents, which standards, which geography.
Methodology: comparables, top-down, or both; the base; apportionment.
Whether essentiality is determined in the arbitration or assumed.
The arbitrators' qualifications.
Whether the award is binding and non-appealable.
Interim measures: no injunctions during the arbitration, and security during it.
Confidentiality, and what may be disclosed to other licensees.

PART NINE — FREQUENTLY ASKED QUESTIONS

What is the first thing we should do when a demand arrives? Respond within three weeks stating willingness to take a FRAND license and requesting charts, essentiality basis, rate basis, and comparables, with a draft confidentiality agreement attached. It commits you to nothing about the rate and it removes the other side's strongest leverage.

Should we deny infringement? Not generally, and not without analysis. Engage technically with the charts instead. A blanket denial reads as unwillingness.

Is our component supplier's license enough? Sometimes. It depends on the license's scope, field, and downstream coverage, and on exhaustion. Ask in writing and read the agreement — this is the first question and it is sometimes dispositive.

Do we have to pay while we dispute? You do not have to pay the demanded amount, but if you continue selling you should provide security in the amount of your own offer. It is the strongest evidence of good faith available.

How long does the essentiality analysis take? Four to six months for a substantial portfolio, and it is the work that determines your number.

Can we be excluded from the market? In United States district court, rarely. At the ITC, yes — the Commission applies public interest factors, not eBay, and your willingness record is the central public interest fact.

Should we take the pool license? If a pool exists and covers relevant patents, usually yes. It is cheaper than bilateral negotiation, it benchmarks the rate, and it is evidence of willingness. Check the contributor list — a pool license does not cover non-contributors.

Who should file first? Whoever has thought through the whole sequence. Filing first sets the forum and frequently the framework, and it draws a response you should have modeled.

Should we propose arbitration? From either side, yes. It resolves what the dispute is actually about, and the proposal itself is a good fact in every forum.

How do these end? A global portfolio license at a negotiated rate, in the large majority of cases. The litigation determines the leverage and the leverage determines the number.

PART NINE-B — WHEN YOU ARE THE SUPPLIER

A component maker sits between the patent holder and the device manufacturer, and it faces a version of this problem that neither of the other guides addresses.

The pressures:

Customers demand indemnity. Device manufacturers want the supplier to warrant that its component does not infringe and to indemnify against SEP claims. Many suppliers give it without pricing it.
Patent holders may prefer to license the device maker, at a device-level base, which produces a far larger royalty than a component-level license would — and which leaves the supplier's customers exposed and unhappy.
The supplier may want a license precisely so it can tell customers they are covered, and a patent holder may decline to grant one.

What a supplier should do:

Decide whether to seek a license at all. A license makes you a better supplier and it costs money; not having one shifts the exposure to customers who will notice.
If you seek one, ask for downstream coverage expressly — a license that covers only your manufacture and sale does not exhaust as to your customers' devices in every analysis, and the customers care about that.
Price the indemnity you give. An unqualified SEP indemnity to a device maker is an open-ended obligation measured by a base you do not control. Cap it, exclude standards-essential patents, or price it into the component.
Coordinate with customers before responding to a demand. Whether the license is taken at your level or theirs affects both of you, and a supplier that negotiates alone may agree to something its customers cannot use.
Keep records of what you implement. Which standard sections, which optional features, which releases. Your customers will need this and so will you.

And the strategic point. The licensing-level question — component or device — is one of the least settled issues in this field and it is being litigated on several continents. A supplier that has thought about its position, priced its indemnities, and coordinated with its customers is in a materially better place than one that discovers the question when a customer forwards a demand letter.

PART TEN — WHERE TO GET HELP

A technical analyst who can map claims to standards. This is a distinct skill from ordinary patent analysis: it requires reading a standard specification, distinguishing mandatory from optional sections, and understanding what an implementation actually does. Firms and consultancies specialize in it, and the work is the substance of the case.

An economist experienced in SEP valuation, not a general damages expert. Top-down analysis, aggregate royalty burdens, and essentiality-adjusted denominators are a specialized literature.

Counsel in each candidate jurisdiction, engaged before anyone files. Anti-suit motion practice moves in days, and a party scrambling to retain foreign counsel after a filing has already lost the initiative.

ITC counsel, separately, if an exclusion order is in play. The Commission's practice, its public interest submissions, and its schedule are unlike district court in every respect.

Your own supply chain and procurement teams. They hold the supplier license information and the indemnity agreements, and the answers to the two questions that most often reduce exposure are in documents they already have.

And your standards participation team, if you have one. The people who attend the SSO meetings know which sections are mandatory, which are optional, what the working group actually adopted, and who declared what. That knowledge is not in any database.

PART ELEVEN — THE ONE-PAGE VERSION

Implementer, before any letter: map which standards your products implement and at what level; ask every supplier in writing whether it is licensed; read the SEP carve-out in your indemnities; and budget SEP royalties as a cost of implementing the standard.

Implementer, week three: respond. State willingness. Request charts, essentiality basis, rate basis, and comparables. Attach a confidentiality agreement. This is the highest-value action available and it is nearly free.

Implementer, months three to eight: do the essentiality analysis. It is expensive and it is the only quantitative input you will have.

Implementer, month eight: make a supported counter-offer with a stated methodology, and place security in the amount of your own offer if you keep selling.

Patent holder, before asserting: do your own essentiality analysis, build the rate basis, audit your license history for discrimination exposure, and settle your licensing-level position.

Patent holder, in the first letter: charts, patents, standard sections, a specific rate, the basis for it, and a confidentiality agreement. A demand without them is quoted against you for years.

Both, throughout: respond promptly and substantively, move when the other side moves, document everything, and keep positions consistent across every forum.

And the framing to hold onto: the doctrine is unsettled and jurisdiction-dependent, but reasonableness is not. The party whose conduct a neutral would call reasonable controls the framing everywhere — and the framing is what sets the price.
