FRAND Royalty Rate: How Courts Actually Price a SEP Licence

A FRAND royalty rate is the fair, reasonable and non-discriminatory price an owner of standard-essential patents (SEPs) may charge to license them — and for years it was more slogan than number. That has changed. English and U.S. courts have now set FRAND rates on the record between parties that could not agree, which means a patent owner, a licensee or anyone valuing an SEP portfolio finally has real anchors to work from instead of a negotiating position dressed up as a principle.

What a FRAND Royalty Rate Really Is

When a company contributes a patented invention to a technical standard such as 5G, the standards body asks it to commit to license any resulting standard-essential patents on FRAND terms. The commitment is the price of getting the invention written into a standard that the whole industry must then implement. In exchange, the owner promises not to hold the industry hostage.

The problem is that “fair, reasonable and non-discriminatory” is not a formula. A FRAND royalty rate has to be reconstructed from evidence — what comparable licences charge, how large and how genuinely essential the portfolio is, and what a reasonable cumulative royalty for the entire standard should be. Those are the questions a court works through, and they are the same questions a credible valuation has to answer.

• Fair and reasonable — the rate reflects the economic value of the patented technology, not the value the standard itself creates by forcing adoption.
• Non-discriminatory — similarly situated licensees should pay similar rates, so an owner cannot quietly favour one implementer over a rival.
• Bounded — every owner’s rate has to fit under one reasonable aggregate royalty for the standard, or royalties stack until the device is uneconomic to build.

The Two Methods Used to Set a FRAND Royalty Rate

Courts and valuers reach a FRAND royalty rate two main ways, and the most defensible analyses use both as a cross-check.

Comparable licences. The cleanest evidence of a market rate is what the owner — or others holding similar portfolios — has actually charged in arm’s-length deals. Real executed licences are hard to argue away, which is why they carry so much weight when a court can get them into evidence.

Top-down. Where comparables are thin or disputed, the top-down method sets an owner’s rate as its proportional share of a reasonable maximum aggregate royalty for the whole standard. You estimate the total royalty the market should bear for all SEPs on the standard, then award each owner a slice proportional to how many genuinely essential patents it holds. The method’s great virtue is that it controls royalty stacking by construction: every slice has to fit under one pie.

Both methods depend on a number most press coverage ignores — how many of an owner’s declared patents are truly essential. Get that wrong and both methods inflate. This is where a disciplined IP valuation earns its fee.

What FRAND Rates Courts Have Actually Set

The era of guesswork is over because several courts have now put FRAND rates on the record between unwilling parties:

• InterDigital v. Lenovo [2023] EWHC 539 (Pat). Mr Justice Mellor set a global rate of 17.5 cents per device for InterDigital’s 3G/4G/5G portfolio — against the owner’s ask of up to 61 cents — producing a lump-sum of US$138.7 million for past and present sales. The Court of Appeal later adjusted the per-unit figure to 22.5 cents.
• TCL v. Ericsson (C.D. Cal. 2017). The U.S. court applied a top-down analysis, working from Ericsson’s own stated expectation of a 6–8% maximum aggregate royalty for 4G, and arrived at 0.45% on U.S. sales for 4G devices (0.314% rest-of-world). The Federal Circuit later vacated the rate-setting on jury-trial grounds, but the methodology became a reference point.
• Unwired Planet v. Huawei [2020] UKSC 37. The UK Supreme Court confirmed an English court may set the terms of a global FRAND licence and injunct an implementer that refuses it.

The lesson is not that any one of these numbers is universal — they are not. It is that a FRAND royalty rate now has gravity. A demand that sits far above the rates courts have set for comparable portfolios is a demand a well-advised implementer will litigate rather than pay.

Why Declared SEP Counts Mislead the Rate

The single biggest error in pricing a FRAND royalty rate is treating a declared SEP count as an essential SEP count. Declaration is self-reported, cheap, and strategically over-done: under-declaring risks losing a royalty, so owners declare generously. The pools balloon as a result — declared granted 5G patent families grew from roughly 25,000 in 2021 to more than 57,000 by October 2024, according to LexisNexis IPlytics.

But independent technical checks tell a very different story. PA Consulting’s 2025 analysis and the European Commission’s JRC pilots both find that only about one in five declared SEPs survive a manual essentiality review. One large sample of over 20,500 families found roughly 4,000 genuinely essential — an essentiality rate near 20%. A rate built on the declared count therefore overstates the base by about five times.

The counts themselves come from declaration databases curated by analytics providers such as LexisNexis IPlytics, and they are invaluable for seeing the shape of the pool. But the same providers are explicit that a declared family is a claim, not a verdict. Treat the database as the start of the analysis, never the end of it, and always discount a headline count for the essentiality rate before any money is attached to it.

Value rank and count rank also diverge. On LexisNexis’s value-weighted index, Qualcomm leads 5G even though Huawei leads on family count. If you want to understand who actually holds the valuable 5G patents rather than the biggest pile of declarations, start with who owns the 5G patents and then discount for essentiality.

Royalty Stacking and the Aggregate Ceiling

A FRAND royalty rate cannot be judged one portfolio at a time, because a 5G handset reads on patents held by dozens of owners. If each one charges what it thinks its portfolio is worth in isolation, the royalties stack until they exceed any sane fraction of the device price. This is the royalty-stacking problem, and it is why the top-down method matters.

In TCL v. Ericsson the court anchored to a cumulative ceiling — Ericsson itself had publicly endorsed a 6–8% maximum aggregate royalty for 4G — and then gave Ericsson only its proportional share of that ceiling. The discipline is that every owner’s rate must be consistent with all the others fitting under the same cap. A rate that would be reasonable alone can still be unFRAND if it only works when every other owner charges nothing.

For an owner, the practical takeaway is that your rate is capped not just by your portfolio’s quality but by the room left under the aggregate ceiling. For an implementer, the ceiling is the strongest argument against a stacked demand.

FRAND Rate-Setting Has Gone Global

Since Unwired Planet, a FRAND royalty rate determined in one willing forum can govern worldwide royalties. An English court will set a global rate and enforce it with an injunction on UK sales if the implementer refuses the global licence. Chinese courts have moved to set global rates as well, and the venue race that followed means the forum now shapes the number.

That is why a modern SEP valuation treats rate and venue as one exercise. The rate you can defend depends on where the dispute is likely to be heard and which comparable rates that forum has already accepted. Our 5G SEP portfolio valuation case study walks through exactly how a declared portfolio is normalised, essentiality-checked, and then priced against these court-set benchmarks.

Turning a FRAND Royalty Rate Into a Negotiation Position

A FRAND royalty rate is only useful if it survives contact with the other side’s lawyers. The owners who do best in licensing are not the ones with the highest ask; they are the ones whose opening number a tribunal would recognise, because that credibility is what moves a reluctant implementer from arguing to paying.

In practice that means three disciplines before the first letter goes out. First, lead with the essentiality-confirmed core of the portfolio rather than the full declaration, so the first claim chart the implementer sees actually reads on the standard. Second, express the rate as a share of a reasonable aggregate royalty, so it is immediately defensible against a royalty-stacking argument. Third, line the number up against the closest comparable the relevant forum has accepted, so the conversation starts inside the range a judge has already blessed.

• For the owner: an ask anchored to court-set comparables converts faster and litigates better than an aspirational rate the counterparty will simply reject.
• For the implementer: the aggregate ceiling and the ~20% essentiality reality are the two strongest levers to pull a stacked demand back toward FRAND.
• For a dealmaker: in an acquisition or financing, the essentiality-checked base — not the declared count — is the number that belongs in the data room.

The same logic runs in reverse for a company on the receiving end of a demand. If the rate sits above the comparable band, or assumes an essentiality rate far above the one-in-five that independent samples report, those are the two pressure points that bring an inflated demand back to earth. Either way, the discipline is identical: rebuild the base, apply a top-down share, and benchmark against what courts have actually done.
