Standard Essential Patent Checklist: Declarations, Essentiality Review, FRAND Offers, Rate Evidence, and Remedies

By Casey Scott McKay · 2025-08-10

This checklist runs a standard essential patent matter from the policy that created the commitment through the licence or judgment that ends it. It opens with the declaration register a holder needs and the exposure map an implementer needs, then the filters that remove exposure cheaply - optional features, supplier coverage, and exhaustion. It sets out the essentiality sampling study both sides should run before any rate is discussed, and the contents of an offer and a counteroffer, including the willingness statement that forecloses an injunction. It then works rate evidence, apportionment, and base selection, and closes with remedies, forum, anti-suit dynamics, and arbitration. Gates mark the points that must clear before an offer is made or a proceeding is filed.

Summary. This checklist runs a standard essential patent matter from the policy that created the commitment through the licence or judgment that ends it. It opens with the declaration register a holder needs and the exposure map an implementer needs, then the filters that remove exposure cheaply — optional features, supplier coverage, and exhaustion. It sets out the essentiality sampling study both sides should run before any rate is discussed, and the contents of an offer and a counteroffer, including the willingness statement that forecloses an injunction. It then works rate evidence, apportionment, and base selection, and closes with remedies, forum, anti-suit dynamics, and arbitration. Gates mark the points that must clear before an offer is made or a proceeding is filed.

Boxes marked [Gate] must clear before an offer is made, a proceeding is filed, or a rate is asserted.

The matter. A demand letter asserting two thousand declared families, with no rate and no charts. Two years later the licence was signed at a figure neither side would have predicted — arrived at by an essentiality sample, a comparability table, and one sentence written in month two.

Phase 1. The applicable policy

[ ] [Gate] Obtain the intellectual property rights policy in force when the declaration was made.
- Why. The commitment is contractual, and its content comes from the policy rather than from any general notion of fairness. Microsoft v. Motorola treats it as an enforceable contract with implementers as third-party beneficiaries.
- Trap. Working from the current policy when the declaration was made under an earlier version.
[ ] Identify what the policy actually requires. A commitment to license, a declaration of willingness, or only disclosure.
- Why. Bodies differ materially, and some impose no licensing obligation at all.
- Trap. Assuming every declaration carries a FRAND licensing commitment.
[ ] Check the affiliate definition.
- Why. Policies typically bind the member and its affiliates, which can commit a whole group's portfolio.
- Trap. A subsidiary's participation committing the parent's patents unnoticed.
[ ] Check the jury-instruction consequence.
- Why. HTC Corporation v. Ericsson confirms the policy's actual language governs rather than a judicial gloss.
- Trap. Briefing a general FRAND standard the policy does not contain.

Phase 2. The declaration register

[ ] [Gate] Build or obtain the register. Family, standards body, policy version, declaration date, and standard.
- Why. A holder that cannot describe what it committed cannot defend a rate or price a transaction.
- Trap. Its absence, which is the ordinary state of affairs.
[ ] Reconcile against the body's public database.
- Why. Declarations made years ago by departed engineers are frequently unknown internally.
- Trap. A register built from internal records that misses declarations the database shows.
[ ] Record the essentiality basis for each declaration, going forward.
- Why. A selectively declared portfolio with recorded reasoning survives sampling far better.
- Trap. Reflexive declaration, which inflates the count and invites the attack.
[ ] Check transfer covenants in the chain of title.
- Why. Policies require transferors to bind assignees, and the commitment travels with the patent.
- Trap. Acquiring declared patents believing they came free of the commitment.

Phase 3. The exposure map

[ ] [Gate] List the standards each product implements, by version.
- Why. Exposure is defined by what the product does, not by what the holder declared.
- Trap. Treating a whole standard as implemented when only a profile is.
[ ] List the optional features implemented and not implemented.
- Why. A patent essential only to an unimplemented optional feature is not infringed.
- Trap. Skipping this filter, which is the cheapest exposure reduction available.
[ ] Identify holders who have declared against those standards.
- Why. It sizes the stacking problem and identifies who is likely to approach next.
- Trap. Responding to each approach in isolation with no view of the aggregate.
[ ] Inventory existing coverage. Direct licences, pool licences, and rights through suppliers.
- Why. Coverage already held removes assertions.
- Trap. Paying twice for patents a supplier already licensed.

Phase 4. Cheap filters

[ ] [Gate] Tender to component suppliers under their indemnity provisions.
- Why. Suppliers frequently indemnify for infringement, and late tender can forfeit the right.
- Trap. Waiting until the complaint arrives; tender on the first letter.
[ ] Check exhaustion on licensed components.
- Why. An authorised sale exhausts rights in the article, and components bought from a licensed supplier may carry exhausted rights. See The Sale That Ends Your Rights.
- Trap. Assuming a supplier's licence covers the buyer without reading its scope.
[ ] Apply the optional-feature filter.
- Why. Patents essential only to features the product does not implement are not infringed under 35 U.S.C. § 271.
- Trap. Accepting a demand framed at the standard level rather than at the implementation level.
[ ] Remove expired, lapsed, and ungranted members.
- Why. Declaration databases retain families long after they cease to matter.
- Trap. Negotiating against a portfolio a third of which no longer exists.
[ ] Check pool coverage.
- Why. A pool licence already held may cover part of the demand.
- Trap. Paying twice.

Phase 5. The essentiality study

[ ] [Gate] Define the population. Declared families with granted claims in the relevant jurisdictions, unexpired.
- Why. The population, not the declaration count, is what is being valued.
- Trap. Sampling from the declared set rather than the live set.
[ ] Draw a random sample of fifty to a hundred families.
- Why. It supports a defensible extrapolation; reviewing thousands does not proportionately improve it.
- Trap. A convenience sample of the patents the other side charted.
[ ] Map claim to specification for each. Independent claim, construction applied, clause of the standard, mandatory or optional.
- Why. This is the analysis; anything less is an assertion.
- Trap. Accepting the holder's mapping without construing the claim.
[ ] Test the counterfactual. Could a compliant implementation avoid the claim?
- Why. That is what essentiality means.
- Trap. Treating "reads on a typical implementation" as essentiality.
[ ] Separate essential-to-standard from essential-to-implemented-features.
- Why. The second is the number that matters to the implementer.
- Trap. Reporting only the first, which overstates.
[ ] Record per-patent reasoning and state the confidence interval.
- Why. The methodology is what is attacked.
- Trap. A headline percentage with no working.

Phase 6. The opening offer

[ ] [Gate] Include a rate, a base, a term, and a territory.
- Why. An offer without a number is not an offer and will not support an unwilling-licensee argument.
- Trap. "We would welcome a discussion," which is a letter rather than an offer.
[ ] Describe the portfolio in granted counts by jurisdiction, not declaration counts.
- Why. Credibility on the rate depends on credibility about the asset.
- Trap. Leading with the headline declaration number.
[ ] Enclose representative claim charts.
- Why. They demonstrate the assertion is real.
- Trap. Charts against the standard rather than against the accused implementation.
[ ] State the basis for the rate and offer a confidentiality agreement for comparables.
- Why. Insisting a rate is justified by licences you will not disclose reads badly later.
- Trap. Withholding comparables while demanding acceptance.
[ ] Check consistency against similarly situated licensees.
- Why. Non-discrimination is half the commitment.
- Trap. An offer materially different from a comparable licensee's with no documented reason.
[ ] Give a reasonable response period without an artificial deadline.
- Why. The conduct record is read by a court years later.
- Trap. A fourteen-day ultimatum on a portfolio demand.

Phase 7. The counteroffer

[ ] [Gate] Include the willingness statement. An unconditional undertaking to take a licence on terms determined to be fair, reasonable, and non-discriminatory by a court or agreed arbitrator.
- Why. It forecloses the hold-out characterisation that is the holder's only realistic route to an injunction under eBay v. MercExchange.
- Trap. Making it conditional on winning on validity or essentiality, which defeats the purpose.
[ ] State a figure with a basis.
- Why. A counteroffer with no number is indistinguishable from delay.
- Trap. Refusing to name a rate for fear of anchoring.
[ ] Give specific reasons. Essentiality findings, unimplemented optional features, supplier coverage, comparability objections.
- Why. Specific objections are credible; general ones are not.
- Trap. Asserting that none of a large portfolio is essential.
[ ] Consider escrow or security for the accruing amount.
- Why. It removes the argument that delay is the strategy.
- Trap. Accruing nothing and then arguing good faith.
[ ] Consolidate information requests into one.
- Why. Serial requests for material already provided are the hold-out record.
- Trap. A rolling series that reads as stalling.
[ ] Respond within a reasonable period, and note the elapsed time.
- Why. Both sides' response times become exhibits.
- Trap. Nine months of silence followed by a substantive response.

Phase 8. Comparable licences

[ ] [Gate] Build the comparability table. Counterparty, date, standards, granted families at the time, territory, term, structure, headline rate, caps, cross-grant, volume assumption, and context.
- Why. It is the evidence, and it takes months.
- Trap. Building it from summaries, which omit caps.
[ ] Flag litigation-driven licences.
- Why. They reflect defence cost rather than technology value, and Ericsson v. D-Link Systems supports discounting.
- Trap. Treating a settlement rate as an arm's-length benchmark.
[ ] Value every cross-grant.
- Why. A net cash figure says nothing about either portfolio without valuing the counter-grant.
- Trap. Using a cross-licensed net figure as a one-way rate.
[ ] Normalise structure. Convert lump sums using a stated volume assumption.
- Why. The assumption is where the disagreement actually lives, and stating it exposes it to testing.
- Trap. An implicit volume assumption buried in an expert's spreadsheet.
[ ] Adjust for portfolio size at the time of each licence.
- Why. A licence granted when the portfolio was half its current size is not comparable without adjustment.
- Trap. Comparing today's portfolio to a five-year-old rate.
[ ] Negotiate the protective order tiers early.
- Why. Comparables are confidential and production depends on the tier structure.
- Trap. Discovering at the production deadline that no attorneys-eyes-only tier exists.

Phase 9. Apportionment

[ ] [Gate] Separate the invention's value from the value conferred by standardisation.
- Why. Ericsson v. D-Link Systems requires it, and it is the element most often missing.
- Trap. An expert who asserts apportionment without showing the step.
[ ] Adapt the Georgia-Pacific v. United States Plywood factors, discarding those that mislead in a standards context.
- Why. The Federal Circuit has directed the adaptation.
- Trap. Reciting all fifteen factors mechanically.
[ ] Avoid rules of thumb.
- Why. Uniloc USA v. Microsoft excluded the twenty-five per cent rule.
- Trap. Any unmoored heuristic dressed as an industry norm.
[ ] Address stacking with evidence — other holders, their demands, and the aggregate.
- Why. Ericsson requires proof rather than assumption.
- Trap. Arguing stacking from the structure of standards generally.

Phase 10. The royalty base

[ ] [Gate] Select the base and justify it on the evidence.
- Why. Apportionment is the requirement; the base is one route to it.
- Trap. Asserting a rule where none exists.
[ ] Consider the smallest saleable practising unit.
- Why. LaserDynamics v. Quanta Computer supports it for multi-component products.
- Trap. Treating it as mandatory when Commonwealth Scientific and Industrial Research Organisation v. Cisco Systems permits a base drawn from real negotiations.
[ ] Test the entire market value alternative honestly.
- Why. VirnetX v. Cisco Systems requires the patented feature to drive demand for the whole product.
- Trap. Using the end product with a small rate as a way around apportionment, which is expressly foreclosed.
[ ] Define the base precisely. The unit, the price measure, deductions, and any caps.
- Why. Ambiguity in the base is where licence disputes start.
- Trap. "Net selling price" with no deduction definition.

Phase 11. Top-down cross-check

[ ] Estimate an aggregate royalty burden for the standard.
- Why. It supplies an independent check on the comparables figure.
- Trap. An aggregate pulled from advocacy rather than from evidence.
[ ] Allocate by the portfolio's share of essential patents, using the sampled essentiality rate.
- Why. This is where the essentiality study earns its cost.
- Trap. Allocating by declaration counts, which reintroduces the inflation.
[ ] [Gate] Compare the two figures.
- Why. Same order of magnitude is what a credible analysis looks like.
- Trap. Presenting a top-down figure that diverges by a factor of ten without explaining it.

Phase 12. Expert preparation

[ ] Engage the damages expert early enough to shape discovery.
- Why. An expert handed whatever was produced cannot build the analysis they need.
- Trap. Retention after the close of fact discovery.
[ ] [Gate] Ensure the apportionment step is explainable in a sentence.
- Why. Federal Rule of Evidence 702 exclusion of the damages expert ends the case in substance.
- Trap. A method that works only inside a model nobody can narrate.
[ ] Document the data, the adjustments, and the reasoning behind every comparability adjustment.
[ ] Sanity-check against product economics.
- Why. A rate exceeding the product's margin will not be paid and costs credibility.
- Trap. A defensible-looking model producing an impossible number.

Phase 13. Injunctions

[ ] [Gate] Run the eBay v. MercExchange factors against the commitment.
- Why. 35 U.S.C. § 283 relief is equitable, and a patentee that promised to license for money has conceded the adequacy of damages.
- Trap. Assuming a per se bar; Apple v. Motorola declines one.
[ ] Assess the implementer's conduct record.
- Why. Refusal to take any licence at any rate is the case where an injunction is realistic.
- Trap. Characterising a counteroffering implementer as unwilling.
[ ] For the implementer: confirm the willingness statement is on the record, unconditional and dated.
[ ] For the holder: confirm the offer contained a rate and a base before arguing unwillingness.
- Why. Unwillingness is measured against what was actually offered.
- Trap. Alleging hold-out after making an offer with no number.

Phase 14. The ITC

[ ] Assess whether 19 U.S.C. § 1337 is available. Importation, infringement of a valid right, and a domestic industry.
- Why. Exclusion orders are not governed by eBay, which makes the forum attractive to holders.
- Trap. Missing the domestic industry requirement.
[ ] Prepare the public interest submission.
- Why. The commitment, the offer record, and the willingness statement all bear on it, and it is where an implementer's negotiation conduct pays off.
- Trap. Treating the Commission proceeding as purely technical.
[ ] Model the timetable against parallel district court proceedings.
[ ] Consider the disapproval possibility and its effect on settlement dynamics.

Phase 15. Forum and parallel proceedings

[ ] [Gate] Decide the remedy pleaded with the jury right in mind.
- Why. TCL Communication v. Ericsson held that a rate determination resolving a legal claim required a jury.
- Trap. Framing the case for a bench determination and losing it on appeal.
[ ] Assess whether the forum will set a global rate, and whether the parties will be bound.
[ ] Consider a declaratory action for the rate and for breach, where the correspondence supports a case or controversy.
[ ] Map parallel proceedings in every jurisdiction with granted members and product sales.
[ ] Anticipate anti-suit and anti-anti-suit motions.
- Why. They escalate, cost heavily, and resolve nothing about the rate.
- Trap. Initiating one without modelling the response.
[ ] Consider inter partes review under 35 U.S.C. § 311 against the asserted subset, with the estoppel and stay consequences.

Phase 16. Arbitration

[ ] Propose it early and in writing.
- Why. The proposal itself is evidence of willingness, and a binding determination avoids the jurisdictional race.
- Trap. Proposing it in year three, when it reads as a litigation tactic.
[ ] Define the scope. Rate only, or rate plus essentiality and validity.
[ ] Agree interim arrangements. Accrual or escrow at an interim rate, and a standstill on injunctive relief pending the award.
[ ] Agree the award's implementation as a licence effective from a stated date.
[ ] [Gate] Confirm both sides will be bound, because a non-binding process is a delay.

Phase 17. Non-discrimination

[ ] [Gate] Compare the offer against terms given to similarly situated licensees.
- Why. Non-discrimination is half the commitment and the comparison is the implementer's best discovery.
- Trap. Terms that vary with no documented reason.
[ ] Document justifications for differences. Volume, term, timing, cross-grant value, market, or currency.
[ ] Define "similarly situated" defensibly, because the definition does most of the work.
[ ] Audit the licence set annually for consistency drift.

Phase 18. Antitrust conduct review

[ ] Review the negotiation conduct as exclusionary conduct, not only as contract performance.
- Why. The two analyses diverge and both apply to the same correspondence.
- Trap. Optimising the contract position into an antitrust exposure.
[ ] Check disclosure conduct at the standards body.
- Why. Broadcom v. Qualcomm treats a deceptive commitment as potentially monopolising, and Rambus v. Federal Trade Commission shows the causation burden.
- Trap. Assuming non-disclosure is automatically actionable, or automatically not.
[ ] Assess refusal and licensing-level theories realistically.
- Why. Federal Trade Commission v. Qualcomm narrowed the duty to deal, and Continental Automotive Systems v. Avanci addressed component-supplier standing.
- Trap. Pleading an antitrust claim that is really a contract claim, without market power or antitrust injury.
[ ] Preserve the misuse defence where the holder has extended the patent's scope anticompetitively.
[ ] Note Allied Tube & Conduit v. Indian Head where the conduct concerns subversion of the standards process itself.

Phase 19. Pools and platforms

[ ] For a holder considering joining: compare portfolio strength against the pool average, since a per-patent share subsidises weaker contributors.
[ ] For an implementer: determine what fraction of the essential landscape the pool covers and what remains unpooled.
[ ] [Gate] Check the pool's governance. Independent essentiality review, complementary rather than substitute patents, non-exclusive licensing, and non-discriminatory terms.
- Why. Those conditions are what make a pool procompetitive.
- Trap. A pool admitting non-essential patents, which combines substitutes.
[ ] Review grantback terms. Narrow, non-exclusive, and limited to essential patents.
[ ] Note that published pool rates become comparables in bilateral disputes, in both directions.

Phase 20. Settlement structure

[ ] Global portfolio licence, since that is what the parties actually need.
[ ] Defined term with renewal or expiry treatment.
[ ] Defined base with caps or tiers, because a rate calibrated to high-value devices is unworkable for low-value ones.
[ ] Release for past acts and a covenant not to sue on the covered portfolio.
[ ] Affiliate coverage on both sides, defined.
[ ] Have-made rights and supply chain coverage, so suppliers are not sued separately.
[ ] Most-favoured terms where negotiable, with a defined comparison mechanism.
[ ] Audit and reporting proportionate to the structure.
[ ] Dispute resolution for rate disputes arising during the term.
[ ] [Gate] Confirm the licence resolves the parallel proceedings in every jurisdiction, with dismissals filed.

Phase 21. Cadence

[ ] On joining a standards body. Policy reviewed, affiliate scope confirmed, engineering-to-legal notification route established.
[ ] On every declaration. Register entry with family, body, policy version, date, and essentiality basis.
[ ] On every assignment. Transfer covenant included and recorded.
[ ] On a first approach. Exposure map, supplier tender, optional-feature filter, and a substantive response with a willingness statement.
[ ] Before any offer. Essentiality sample run, portfolio described in granted counts, consistency checked against similarly situated licensees.
[ ] Quarterly during a negotiation. Correspondence reviewed as an evidentiary record; elapsed times noted.
[ ] Annually for a programme. Register refreshed, rate card reviewed against expiries, non-discrimination audited, comparability table updated.
[ ] On any transaction. Declared-patent encumbrance identified and priced.

Phase 22. The essentiality study template

| # | Family | Jurisdiction | Granted | Independent claim | Construction applied | Standard clause | Mandatory? | Implemented by product? | Avoidable? | Essential? | |---|---|---|---|---|---|---|---|---|---|---| | 1 | [X] | US | Yes | Claim 1 | [term: meaning] | § 5.3.2 | Yes | Yes | No | Yes | | 2 | [Y] | US | Yes | Claim 1 | [term: meaning] | § 7.1 (optional) | No | No | — | Not in issue | | 3 | [Z] | US | Yes | Claim 1 | [term: meaning] | § 4.4 | Yes | Yes | Yes — alternative in § 4.4.2 | No |

One row per sampled family, with the reasoning recorded separately per row.
"Avoidable?" is the operative column — it is what essentiality actually means.
"Implemented by product?" produces the second number, which is the one an implementer negotiates against.
Report both rates: essential to mandatory provisions, and essential to implemented features.
State the sample size, the population, and the confidence interval.
Retain the per-patent analyses, because the methodology is attacked before the conclusion is.

Phase 23. Three worked situations

The demand with no number. A letter asserts a large declared portfolio, demands a meeting, and names no rate. The implementer's response should acknowledge, request charts and portfolio detail, give the unconditional willingness statement, and propose a confidentiality agreement. That response costs an afternoon and it removes the injunction, converts the matter into a price dispute, and starts the elapsed-time clock running against the holder rather than the implementer.

The portfolio that shrinks. Two thousand declared families reduce to six hundred live granted families, then by a fifth for unimplemented optional features, then to roughly a third on sampled essentiality. The asset is an order of magnitude smaller than the letter described. Presented properly — with methodology, per-patent reasoning, and a stated confidence interval — this is the single most effective move available to a defence, and it is available in months rather than years.

The comparables that are not comparable. Eleven licences produced. Four settle litigation and are discounted under Ericsson v. D-Link Systems. Three carry cross-grants whose counter-value nobody has assessed. Two contain per-unit caps that halve the effective rate. Two are genuinely arm's-length, current, and comparable in scope. Those two anchor the case, and the side that built the table properly is the side whose expert survives Federal Rule of Evidence 702.

Phase 24. Working with other advisers

[ ] Technical experts for claim-to-standard mapping. Specialist work that general patent litigators cannot substitute for.
[ ] Damages experts engaged early enough to shape discovery rather than to interpret it.
[ ] Antitrust counsel, reviewing the offer terms and negotiation conduct on both the contract and the competition analysis.
[ ] Standards participants inside the client — usually engineers, and frequently the only people who know what was declared and when.
[ ] Foreign counsel in every jurisdiction with granted members and product sales.
[ ] ITC counsel where an exclusion order is sought or faced.
[ ] Procurement and supply chain, for indemnity tender and for identifying licensed components carrying exhausted rights.
[ ] Finance, because the litigate-or-settle decision is two rates over a volume and a term.

Phase 25. Sector boxes

[ ] Cellular and connectivity. The archetype and the source of most authority. Large declared portfolios, device-level licensing, component supplier disputes, and attempts at global rate setting.
[ ] Wi-Fi and short-range wireless. Ericsson v. D-Link Systems and Commonwealth Scientific and Industrial Research Organisation v. Cisco Systems both arose here, and the base question — chip, card, or end product — is at its starkest.
[ ] Video codecs. Multiple pools plus unpooled holders, which makes the stacking analysis genuinely necessary rather than rhetorical.
[ ] Automotive. The most contested licensing-level sector; Continental Automotive Systems v. Avanci is the leading American treatment.
[ ] Internet of things. Low-value devices implementing high-value standards, where caps and tiers do the work a percentage rate cannot.
[ ] Healthcare and device interoperability. Weaker intellectual property rights policies shift the analysis toward ordinary patent law under 35 U.S.C. § 271 and 35 U.S.C. § 284.
[ ] Royalty-free standards. A different commitment — a promise not to charge — and breach is a simpler contract claim.
[ ] Portfolio acquisitions. Declarations travel with the patents; diligence that skips declaration databases misprices the asset.

Phase 26. The one-page position

SEP position — [matter], [date]. Role: [holder / implementer]. Standard(s) [list]; body [name]; policy version [date]. Portfolio: [N] declared families, [N] live granted in [jurisdictions], [N] expired or lapsed. Optional features implemented: [list]; families removed by that filter: [N]. Supplier coverage and exhaustion assessed [date]; indemnity tendered to [suppliers] on [dates]. Essentiality study: sample [N], completed [date]; essential to mandatory provisions [N per cent]; essential to implemented features [N per cent]; confidence interval [range]. Negotiation record: offer [date] — rate [stated/not], base [defined/not], charts [N]; response [date]; willingness statement [given/received] [date]; counteroffer [date]. Elapsed times: [days per step]. Comparables: [N] in table; [N] litigation-driven; [N] cross-granted; [N] capped; [N] genuinely comparable. Rate: comparables-based [figure]; top-down [figure]; apportionment method [described]; expert retained [date]. Base: proposed [X] on authority of LaserDynamics / CSIRO. Remedies: injunction under eBay assessed [available/unlikely]; ITC [filed/not]; parallel proceedings [jurisdictions]; anti-suit [status]; arbitration proposed [date/not]. Non-discrimination: compared against [N] similarly situated licensees, differences documented [yes/no]. Antitrust conduct reviewed [date]. Recommended actions: [issue willingness statement / run essentiality sample / build comparability table / revise offer to include rate and base / propose arbitration].

Phase 27. What this costs

[ ] The register or exposure map. Days, and the precondition to everything else.
[ ] Cheap filters. Hours. Optional features, supplier coverage, and expired members together typically remove a third or more of a demand at almost no cost.
[ ] The essentiality sample. Weeks of technical and legal work; the highest-return spend available to either side and routinely deferred until it is worth far less.
[ ] The comparability table. Months for a holder with an archive; a discovery campaign for an implementer.
[ ] Damages expert work. Front-loaded and substantial, and the point at which an unexplainable apportionment ends the case under Federal Rule of Evidence 702.
[ ] District court and ITC proceedings running in parallel, in several jurisdictions.
[ ] Anti-suit motion practice, which is pure cost producing no rate.
[ ] Arbitration, a fraction of the parallel-litigation total, producing the determination both sides need.
[ ] Against all of it: the rate difference over the term. In a substantial portfolio, small movement in the base or rate outweighs both litigation budgets — which is why the analysis that narrows the gap earliest is the one that pays for itself.

Phase 28. If you can only do four things

[ ] Write the willingness statement if you are the implementer. One unconditional sentence, dated, on the record. It removes the injunction.
[ ] Put a rate and a base in the offer if you are the holder. Without them there is no offer and no unwilling-licensee argument later.
[ ] Run the essentiality sample whichever side you are on, before any rate is discussed.
[ ] Build the comparability table properly, with cross-grants valued and caps recorded, because it is the evidence and the side that prepares it well is the side whose expert survives.

Phase 29. Scoping and the client conversation

[ ] Say early that there will be a licence. The implementer cannot leave the standard and the holder cannot exclude it. The only variables are price and cost.
[ ] Frame the decision as two rates over a volume and a term. That is what the litigate-or-settle choice actually is, and finance can evaluate it in that form.
[ ] Set expectations on the essentiality study. Weeks, real cost, and the analysis that moves the number more than anything else.
[ ] Explain the willingness statement to an implementer client who will instinctively resist conceding anything. It concedes nothing about validity, essentiality, or infringement, and it removes the exclusion risk.
[ ] Explain the offer discipline to a holder client who wants to open with a large number and no detail. An indefensible opening offer is evidence in the breach analysis and it costs the injunction argument later.
[ ] Identify the decision the client is making, and scope the work to it. Diligence that does not change a decision is expensive reading.
[ ] Be candid about parallel proceedings. They multiply cost, escalate unpredictably, and do not produce a rate. Say so before the first foreign filing rather than after the third.

[ ] And agree in advance what a good outcome looks like — a rate, a term, a cap, and a date — so that settlement authority exists before the negotiation reaches the point where it is needed.

Outcome. The register showed two thousand declared families, of which six hundred had granted claims in the relevant jurisdictions and were unexpired. The optional-feature filter removed a further fifth, because the product implemented a profile that excluded two heavily covered features. An essentiality sample of seventy families found roughly a third essential to implemented mandatory provisions — so the asset actually in issue was an order of magnitude smaller than the demand letter described. A willingness statement issued in month two removed the injunction under eBay v. MercExchange and became the first exhibit in the public interest submission when the holder filed at the Commission. Eleven comparable licences were produced under an attorneys-eyes-only tier; four were litigation settlements, three carried substantial cross-grants, and two contained caps that halved the effective rate, leaving two genuinely comparable agreements to anchor the analysis. A top-down cross-check using the sampled essentiality share landed within a factor of two of the comparables figure, which is what made settlement possible. The licence signed in month twenty-four was global, five years, capped, and priced between the parties' positions. No individual patent was ever tried.

The five things people get wrong

Negotiating from declaration counts. Declared is not essential, the gap is large and measurable, and a demand built on the headline number invites the attack that follows.

An opening offer with no rate and no base. It is not an offer, and it will not support an unwilling-licensee argument when the injunction is sought.

No willingness statement from the implementer. One sentence removes the only realistic route to an injunction under eBay v. MercExchange, and it is routinely omitted.

Comparable licences produced without adjustment for structure, scope, caps, cross-grants, and litigation context — which makes them evidence for whoever adjusts them properly.

Asserting hold-up or stacking without evidence, which Ericsson v. D-Link Systems forecloses and which costs credibility on the arguments that are supportable.
