This guide breaks down the UK High Court's August 2024 InterDigital v Lenovo FRAND ruling.

It explains how to verify whether a recalculated offer uses a global sales base, and how to compare like-for-like totals before committing.

## How It Works

The key terms at stake are "global sales base," "per-unit royalty," and "top-down FRAND methodology." Under the top-down approach, courts first estimate the value of the relevant technology space as a percentage of total industry revenue, then allocate that percentage to individual patents based on each patent's contribution. The InterDigital v Lenovo dispute turned on how the royalty base is defined, and ipfray.com reports the resulting UK per-unit rate at 22.5 cents, up from 17.5 cents, against InterDigital's 49-cent ask. Before treating any broader ruling detail as settled for your own deal, verify the judgment itself and confirm in writing which products and territories your proposed base covers — do not assume a global base applies to your license without seeing it defined.

This mechanism creates a powerful incentive for SEP holders to renegotiate existing royalty agreements before litigation becomes unavoidable. A patent portfolio owner with global licensing relationships can now argue that any royalty calculated on a narrower territorial base undervalues the true contribution of its patents across all markets. Conversely, implementers gain leverage to demand recalculation using the broader global sales figure, which tends to produce lower per-unit rates than a territorial calculation would yield. The practical upshot: both parties benefit from early, good-faith negotiation because the court's framework makes the stakes of delay quantifiable and substantial.

For anyone evaluating whether to commit to a SEP license agreement, the critical check is this: does your proposed royalty structure use global unit volumes as the royalty base? If it uses domestic-only volumes, you are operating under a framework the court has now rejected. Compare your current royalty schedule against what a global-sales-based calculation would produce—the difference is often material enough to justify renegotiation before filing suit. The InterDigital v Lenovo ruling gives implementers a defensible, court-endorsed method to challenge underpriced royalties and gives SEP holders a clear reason to revisit historical agreements with a global-sales lens.

## Key Factors to Consider

When deciding whether to accept or push back on a recalculated FRAND offer, the first criterion to lock in is the sales base. Before committing to any total, get the exact definition in writing: which products, which territories, and whether it is truly global sales or a carveout. The base is the multiplier, so a vague "global" label is not enough to compare like-for-like totals and terms.

The second criterion is the per-unit rate applied to that base. According to ipfray.com reporting on the UK matter, the resulting per-unit royalty moved to 22.5 cents per unit from 17.5 cents per unit, while InterDigital wanted 49 cents per unit. Treat those reported figures strictly as test points against a live proposal, not as a default for every portfolio. If a new offer cannot show which of those points it is closest to and why, do not accept a blended rate.

The third criterion is the verifiable total. Do not rely on a single "total due" line. Instead, require the covered unit count for the exact base, multiply it by the confirmed per-unit, and write that total down yourself. If the unit count is withheld or given in a different grouping than the base, the total cannot be verified, so commitment must wait.

For the numbers that matter, only three per-unit figures are directly verifiable from the provided grounding: 17.5 cents per unit, 22.5 cents per unit, and 49 cents per unit. The spread between 22.5 cents per unit and 49 cents per unit is the clearest reported gap to watch for compression, but only when both are applied to the identical base. No other rate, percent, or fee can be pulled from the available sources, so any other number in an offer must be treated as unverified until shown in full.

Before signing off on any recalculation, run this three-point check on the live, complete option: base, per-unit, and total. If even one of those three cannot be produced in writing for the same scope, the correct action is to verify, not to commit. That is the only way to use the reported numbers without guessing.

## Common Mistakes

One of the first errors to watch for is treating a legacy offer as directly comparable to one recalculated by global sales. For example, an implementer may have accepted a quote in the past that was built off of a much narrower sales base, but if they only compare a single per-unit line without forcing both offers to show a full total by the exact product list, they can be misled by scope alone. The check is not to ask for a lower unit figure, but to demand a written total sheet for both options using identical product categories before committing to either one.

A second pitfall is assuming every licensed product is counted under the same rule. Public reporting from ipfray.com has shown that different per-unit figures have been referenced in discussion of the UK matter, but that alone does not prove a uniform treatment across product families. Because of that, the concrete example to guard against is bundling: if an offer groups unrelated product lines together under one total without breaking them out, insist on a line-by-line count. A carve-out for even one product family can change the total without changing the headline language of the offer.

It can also be tempting to lean on broad corporate results to gauge reasonableness, but that is a separate check. InterDigital's public earnings — reported by finance.yahoo.com and noted in the takeaways above — are context only: consolidated figures do not reveal which specific sales fall under a particular license. Treat public earnings strictly as context, and never substitute them for license-level sales data that can be verified against the offer itself.

Finally, outside commentary about a portfolio should not be used to justify accepting or rejecting a total. TheStreet has reported that investors question InterDigital’s market value relative to its patent portfolio, but that valuation debate has no bearing on the arithmetic of a specific FRAND total. The rule for this pitfall is to ignore portfolio talk entirely and only judge the offer by the written totals and terms placed in front of you for verification.

## Insider Tactics

A non-obvious strategy is to flip the negotiation order entirely. Instead of pushing back on the proposed global total itself, make the written reconciliation of the sales base the deliverable that must come first. Ask for that reconciliation at a line level with the ability to verify a sample against your own records, and make your agreement to the total strictly contingent on that deliverable. This is a procedural lever, not a challenge to scope. The check is to never accept a single consolidated figure as proof of the base, no matter how complete it is presented to be.

For timing, do not rely on tone or urgency. Public signals can be useful, but only if verified. As noted by Seeking Alpha, InterDigital has publicly stated it is pursuing the remaining portion of the PC market and negotiating with other vendor groups. That stated pursuit can create pressure to show progress, but it does not obligate you to compress review time. The rule is to request the reconciliation in writing and explicitly ask for the form of the offer to remain reviewable while that reconciliation is provided. Do not infer any constraint from a verbal push, only from a written communication.

Another timing check is to keep the exchange narrow at this exact moment. Avoid bundling unrelated portfolios into the same response while you are only trying to verify the global sales base for this recalculation. Keeping the scope of your reply limited prevents the review of one deliverable from being used to imply acceptance of others, without expanding the negotiation beyond what is being presented.

Finally, treat every version of the offer as unverified until it matches the reconciliation you requested. Document each version and each response in sequence, and only compare like-for-like totals and terms once the base has been matched to a version you can confirm. This is procedural discipline: verify the live, complete option before committing, and do not let version drift go unchecked.

## Comparison

| Option | Per-unit rate | Total on 10M units | Gap vs. court rate |
| --- | --- | --- | --- |
| Prior license | $0.175 | $1,750,000 | −$500,000 (−22.2%) |
| Court FRAND rate | $0.225 | $2,250,000 | — |
| Holder's opening ask | $0.49 | $4,900,000 | +$2,650,000 (+117.8%) |

Two ratios do the real work, and both are worth recomputing by hand before any meeting. The court rate sits 28.6% above the prior license (22.5 ÷ 17.5 = 1.2857) and 54.1% below the ask (26.5 ÷ 49 = 0.5408). Those two percentages bracket the entire negotiation: anything above 22.5 cents on a comparable base is a premium over the judicially tested number, and anything near 49 cents is more than double it. Neither percentage is a term you can cite as binding outside this dispute, but both are checkable from the four numbers above.

Each option wins under a specific, testable condition. The prior license wins only if its sales base is genuinely narrower — a documented territory or product carve-out — because then the lower rate compounds against a smaller multiplier. The holder's ask wins only if you accept it without a base comparison; on identical volume it costs $2.65 million more per 10 million units than the court rate. The court-set rate wins when you ship globally, because it prices the whole base at a number a court has already stress-tested against the holder's demand.

**On like-for-like totals, the court-set 22.5-cent rate is the winner** — it beats the ask by 54.1% on the same volume and buys global coverage for a 28.6% uplift over the old per-unit figure. Verify the base before you bank that conclusion: confirm in writing that the products, territories, and units counted under the prior license match the units counted under the new offer. If the old deal quietly covered worldwide shipments, the 28.6% uplift is the true price of the recalculation; if it covered a subset, your savings are larger than the table shows. For context on how hard the ask will be defended, InterDigital reported Q3 2026 revenue of $193.4 million, up 17% year over year, with Adjusted EBITDA of $131.3 million, up 25% (Yahoo Finance) — a growing licensing line, not a distressed one.

Run the table at your own annual volume rather than the illustrative 10 million units used above, and re-derive both percentages from your own figures before committing. The rule is simple: compare totals on one base, then pick.
