SEP Essentiality Evaluation
An essentiality evaluation checks whether a patent claim has to be practised to implement a standard, or a mandatory part of it. We work through the specification text section by section and report whether each claim you bring us reads on mandatory or optional material.
Who it's for: SEP holders sorting a portfolio, implementers assessing a licensing demand, and patent pools or brokers verifying declared families.
Illustration of the idea. Each family in a real report gets its own finding, not a place on one line.
What the evaluation covers
If you hold a portfolio and want to find the assets that are essential to a given standard, we can help you narrow it down quickly. Specification documents reference one another, so understanding how different specs and versions relate to each other matters as much as reading any single claim.
SEP holders
Sorting a portfolio to see which families are worth declaring or defending.
Implementers
Checking whether a licensing demand actually reads on mandatory spec material.
Pools and brokers
Verifying declared families before submission or a transaction.
How we work through a claim
We read the specification passages tied to each claim and trace how they connect to the inventive step being asserted, then check that reading against related specs and their versions.
| Step | What it establishes |
|---|---|
| Claim to spec mapping | Which specification passages the claim actually reads on |
| Version tracing | Whether the mapping holds across earlier and later versions of the spec |
| Mandatory / optional check | Whether the mapped passage is required to implement the standard or is elective |
Standards we work against
Our in-house ETSI declaration and essentiality databases sit behind each evaluation, so a claim can be checked against the current spec text without starting from scratch.
Mandatory vs. optional, in practice
Mandatory
The standard can't be implemented, or a required part of it can't be met, without practising the claim.
Optional
The claim touches a feature or profile a compliant implementation is free to skip.
We record the finding at the claim level, family by family, rather than giving the portfolio a single label.
Declared vs. non-declared patents
| Declared families | Non-declared portfolios | |
|---|---|---|
| Starting point | The sections the family was declared against | The full standard, to see what the portfolio reads on |
| Question asked | Does the claim actually read on what was declared | Which families read on the standard at all |
| Typical use | Pool submission, licensing rounds | Portfolio triage, acquisition due diligence |
What you receive
- An essentiality determination for each patent against the named standard versions
- Claim to specification mapping showing mandatory and optional sections
- Notes on specification dependencies and version differences
- A summary table ready for pool submission or negotiation
Frequently asked questions
What does essentiality mean for a patent?
A patent is essential to a standard when the standard, or a mandatory part of it, can't be implemented without practising the claim. We check each claim against the specification text, section by section, and record whether it reads on mandatory or optional features.
Do you assess declared and undeclared patents?
Both. Declared families are checked against the sections they were declared for. For undeclared portfolios, we identify which families read on the standard and which don't.
Which standards do you cover?
Wi-Fi 6 and Wi-Fi 7, HEVC, VVC, AV1, VP9, 4G and 5G, NB-IoT and V2X, among others. Our in-house ETSI declaration and essentiality databases support the work.
