Standard Essential Patents Explained: Declarations, FRAND, Pools and What Changed in 2026

Standard essential patents (SEPs) are patents that claim technology a product must use to comply with a technical standard such as Wi-Fi, 5G or a video codec. Owners declare them to standards bodies and commit to license them on fair, reasonable and non-discriminatory (FRAND) terms. But a declaration is the owner’s own statement. ETSI, for example, makes no representation that patents in its declaration database are essential or valid, and the gap between “declared” and “essential” drives many SEP disputes.

What makes a patent “standard essential”

A standard is a shared technical specification. Wi-Fi 6 is IEEE 802.11ax and Wi-Fi 7 is 802.11be. HEVC (H.265), VVC (H.266) and AV1 are video codecs. Every compliant product implements the mandatory parts of its standard.

A patent is essential, in the sense standards bodies use, when a compliant product cannot be made without practicing at least one of its claims. At its core this is a comparison of claim language against specification text, though in a dispute it is decided as a legal question. Designing around is not an option, because the standard fixes the design. That is why SEPs carry special licensing commitments.

Declarations: how SEPs get on the record

Take ETSI, the European Telecommunications Standards Institute. Under its IPR policy, a member that knows it holds a potentially essential patent must inform the Director-General in a timely fashion. It is then asked for an irrevocable written undertaking that it is prepared to grant licenses on FRAND terms. Those declarations go into a public database. When we checked, ETSI’s IPR database listed 6,695 declarations.

Three features of the system matter for anyone reading SEP data:

• Owners declare. The database describes patents declared “essential or potentially essential.” The ETSI Secretariat makes no representation about the accuracy, completeness, validity or essentiality of what is declared.
• Declarations can come early. Owners can declare while the standard is still being drafted and before their own claims are final. Claims can narrow during examination, and a later version of the standard can drop the feature.
• Incentives can push toward over-inclusion. Declaring costs little, and a larger declared portfolio can strengthen a negotiating position. Failing to declare can create its own disputes.

FRAND in plain terms

FRAND stands for fair, reasonable and non-discriminatory. The commitment means the owner will offer a license on such terms. It does not say what those terms are. ETSI states that it is not responsible for determining whether licensing terms disclosed to it are FRAND, and that it takes no position on how its policy should be interpreted.

So rates are set by bilateral negotiation, by pools, and in disputes by courts. Those disputes now reach pools as well as individual owners. In July 2026, the UK Supreme Court ruled that certain claims Tesla brought about Avanci’s 5G Vehicle program should proceed to trial in the High Court. In Avanci’s statement, the court “did not determine whether the Avanci 5G Vehicle license is subject to FRAND.” The merits are now for the High Court.

Patent pools: one license, many owners

A pool gathers patents from several owners for one standard and licenses them through one administrator. For licensees, it replaces dozens of negotiations with one. For owners, it offers one program that reaches many licensees. Pools can also screen what goes in. Sisvel, for example, says every family in its Wi-Fi Multimode pool undergoes “an essentiality evaluation by certified independent evaluators.”

The 2026 pool picture

Two more video developments stand out. Access Advance now runs VCL Advance, the HEVC/VVC program it acquired from Via LA. And in August 2026 it opened an exploration phase for an AV1 and AV2 device and software pool, inviting owners who believe in good faith that they hold essential patents. It expects licensors to approve adding AV2 to the VDP Pool license in 2027.

The rates above are third-party pool rates, published by the administrators. They are context for how pools price, not a benchmark for any particular portfolio.

Why essentiality is contested

Even honest declarations produce disagreement, for structural reasons:

• Claim scope versus spec text. A claim can read on one way of implementing a section but not another, and both can comply.
• Optional features. Standards contain optional modes. A patent that covers only an optional feature is essential only to products that implement it.
• Versions. A patent can map to one release of a standard and not the next.
• Validity is separate. Essentiality asks whether the claims cover the standard. Whether those claims survive a validity challenge is a different question, decided elsewhere.

Policymakers have looked for a better filter. In 2020 the European Commission’s Joint Research Centre published a pilot study on essentiality assessment. It tested independent assessments on declared patents and concluded that a system of essentiality scrutiny appears feasible, and that interest in transparent essentiality data is strong.

Declared versus essential: what the data can and can’t tell you

The step that narrows the gap is technical: mapping each claim element to the specific section, clause and version of the standard it relates to, and noting whether that feature is mandatory or optional. That mapping doesn’t decide essentiality. It does show where a declared portfolio is concentrated and where it is thin.

Questions to answer before any SEP conversation

If you make products that implement a standard:

• Which standards, versions and optional features does each product actually implement?
• Which pools cover those standards, and which declared owners sit outside every pool?
• Do a pool’s licensed-product categories match how you sell (finished device, component, service)?
• Where are the declared families concentrated: mandatory sections, or optional features you don’t use?

If you own patents you believe are essential:

• Which claim elements map to which clauses, and in which versions of the standard?
• Are those clauses mandatory or optional?
• Have the patents been declared, and do the declarations match the claims as granted?
• Would a pool’s independent evaluation, or a bilateral program, suit the portfolio better?

The answers won’t settle a negotiation. They do keep the discussion on evidence rather than on declaration counts.

How Meta Dragons can help

Our Standards & SEP Mapping service maps declared patents against the sections of standards such as Wi-Fi 6/7, cellular and video codecs, with claim-to-specification concordance tables in 3–5 weeks. We give no essentiality opinions. The tables are technical evidence for your counsel and negotiators. To see who else is filing around a standard, a Patent Landscape & Whitespace study adds filing trends and assignee maps. For keeping up once the map exists, see patent monitoring without alert fatigue.
