Case Study: 5G SEP Portfolio Valuation: Pricing a Portfolio Past the Declared Count

The deliverable was a valuation the client could defend in a negotiation, not a number it would have to retreat from. Every figure below is a scenario figure illustrating the shape of the work, not a measured result for a named client.

• A declared base cut to an essentiality-checked base roughly one-fifth its headline size, with the surviving families mapped to the 3GPP specifications they read on.
• A top-down proportional share expressed as a defensible fraction of the standard, rather than a raw count.
• A per-device value band anchored between the court-set floor (InterDigital’s 17.5–22.5 cents for a multi-generation portfolio) and the aggregate-cap ceiling implied by the 6–8% stacking logic.
• A tiered portfolio: a core of strong, essentiality-confirmed families to lead any campaign, a middle tier to license in bulk, and a long tail flagged for pruning to cut renewal spend.
• A negotiation memo matching the valuation to specific comparable licences, so business development opened at a number a tribunal would recognise.

With that in hand, the client reset its opening ask downward to a rate inside the comparable range, led with its confirmed-essential core instead of its full declaration, and stopped paying renewals on a tail that added nothing to the valuation. It entered licensing talks pricing its portfolio the way a court would, which is the only pricing that survives contact with a well-advised implementer.

What This Means for Similar Matters

The lesson that travels beyond this matter is that a 5G SEP portfolio valuation is an essentiality exercise before it is a financial one. A declared count inflated by cheap over-declaration is not an asset base; the ~20% that survives a manual check is. Owners who skip that step negotiate against a number their counterparty has already discounted.

The second lesson is that FRAND is bounded by precedent. The English and U.S. courts have now set rates between unwilling parties on the record, and an aggregate-royalty ceiling constrains what any single owner can command. A valuation that ignores those anchors prices a portfolio in a market that no longer exists.

Why the Forum Now Shapes the Number: Global Rate-Setting

A 5G SEP valuation can no longer assume the dispute stays national. In Unwired Planet v. Huawei [2020] UKSC 37, the UK Supreme Court confirmed that an English court can set the terms of a global FRAND licence to a portfolio of declared SEPs, and can grant an injunction on UK patents if an implementer refuses to take that global licence. That changed the stakes of valuation: a rate determined in one willing forum can govern worldwide royalties.

For an owner, the practical consequence is that a valuation must survive in the forum most likely to hear the case, and must be consistent with the comparable rates that forum has already accepted. For an implementer, it means a portfolio’s value is partly a function of where it can be litigated. Either way, the valuation and the venue strategy are now one exercise, not two.

Frequently Asked Questions

A 5G SEP portfolio valuation has to answer one question a declared-patent count can never answer: of everything a company has told a standards body is essential, how much would actually hold up, and what would a licensee pay for it? This representative engagement shows how PerspireIP valued a mid-size operator’s declared 5G portfolio by stripping it down from a headline family count to a defensible, essentiality-checked base, and then benchmarking that base against the FRAND rates courts have actually set.

The Challenge

A telecommunications-equipment company preparing a licensing campaign asked us to put a defensible number on its declared 5G standard-essential patent (SEP) portfolio before it sent a single demand letter. Its internal deck led with a count of declared patent families, because that is the figure the trade press ranks. The board wanted to know whether that count translated into revenue, or into an embarrassment the moment a sophisticated implementer pushed back.

The risk was concrete. The pool the client was measuring itself against had more than doubled in three years — from roughly 25,000 declared granted 5G families in 2021 to more than 57,000 by October 2024, according to LexisNexis IPlytics data — and China-headquartered owners alone account for over 40% of those families. In a pool growing that fast, a declared count is a vanity metric. A buyer, a court or a licensee discounts it on sight. The client needed a valuation built on what survives scrutiny, not on what was declared.

Our Approach

We ran the 5G SEP portfolio valuation in four stages, because the gap between a declared portfolio and a bankable one opens at a different stage than most owners assume. A disciplined valuation never multiplies a declared count by a per-unit rate; it rebuilds the count first.

• Declared-to-granted normalisation. We separated declared families from granted, in-force families, split by jurisdiction, and removed duplicates, abandoned cases and declarations tied to withdrawn standard contributions.
• Essentiality sampling. We claim-charted a statistically meaningful sample against the specific 3GPP technical specifications cited, because declaration is self-reported and cheap while a manual check is neither. Independent studies — PA Consulting’s 2025 work and the European Commission’s JRC pilots — repeatedly find only about one in five declared families survive a manual essentiality check.
• Top-down framing. We placed the surviving essential families inside the total pool of truly essential 5G families to derive a proportional share, the method the U.S. court adopted in TCL v. Ericsson, where the royalty equals an owner’s share of a reasonable aggregate royalty burden for the standard.
• Comparable-licence benchmarking. We anchored the share to rates courts have actually determined between unwilling parties, rather than to the client’s aspirational ask.

Each stage fed the next. The essentiality rate set the real base; the top-down share converted that base into a fraction of the standard; the comparable rates converted the fraction into money per device. Only then did a portfolio-level number mean anything.

What the 5G SEP Portfolio Valuation Actually Showed

The decisive finding in any 5G SEP portfolio valuation is the essentiality haircut, and this engagement was no exception. The headline declared count overstated the enforceable base by roughly a factor of five. Applying an essentiality rate in line with the ~20% that independent samples report — one study assessed over 20,500 families and found around 4,000 genuinely essential — turned an impressive-looking declaration into a much smaller set of families that would survive a claim chart in a hearing room.

The second finding was that declared rank and value rank are not the same list. LexisNexis’s value-weighted Patent Asset Index puts Qualcomm ahead of Huawei on 5G value even though Huawei leads on family count, with Samsung moving up on quality. A portfolio can sit mid-table on counts and higher on value, or the reverse, and only a value-weighted read tells an owner which position it actually holds.

The third finding was the benchmark ceiling. The client’s draft ask sat well above the rates courts have set between mutually unwilling parties. In InterDigital v. Lenovo [2023] EWHC 539 (Pat), Mr Justice Mellor set a global rate of 17.5 cents per device across a multi-generation (3G/4G/5G) portfolio — against InterDigital’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. In TCL v. Ericsson, the U.S. court worked from Ericsson’s own stated expectation of a 6–8% maximum aggregate royalty for 4G and arrived at 0.45% on U.S. sales. Those numbers set the gravity a 5G demand has to work within.

The Outcome

The deliverable was a valuation the client could defend in a negotiation, not a number it would have to retreat from. Every figure below is a scenario figure illustrating the shape of the work, not a measured result for a named client.

• A declared base cut to an essentiality-checked base roughly one-fifth its headline size, with the surviving families mapped to the 3GPP specifications they read on.
