When field-of-use limits are ignored: what it costs to be wrong
A field-of-use limit restricts a licence to one purpose, product line, or market segment. When a licensee steps outside it, the cost of being wrong is not a fixed penalty. It is the difference between a contract dispute and an infringement claim — and that difference changes forum, remedies, and how fast a claim expires.
The basis: what governs the field-of-use limit
How a field-of-use clause is drafted decides which regime applies. If the licence is for an EU trade mark and the clause fixes the goods or services covered, contravening it lets the proprietor invoke trade mark rights directly against the licensee under Regulation (EU) 2017/1001. The claim then runs as an infringement action, not as a breach of contract.
If the licence is for a computer program, the scope of use granted to the lawful acquirer is defined by Directive 2009/24/EC. Use outside that scope is unauthorised reproduction or adaptation, not merely a broken promise.
If the licence covers a database, the same logic applies under Directive 96/9/EC: extraction or reuse beyond the agreed field is measured against the database right, not against the contract alone.
Patent licences carry the same tension, but no EU regulation fixes how a field-of-use breach is characterised there. The applicable national patent statute, together with the exact wording of the licence, decides it.
| Right licensed | Governing basis | What ignoring the limit becomes |
|---|---|---|
| EU trade mark | Regulation (EU) 2017/1001 | Infringement claim available to the proprietor |
| Computer program | Directive 2009/24/EC | Unauthorised reproduction or adaptation |
| Database | Directive 96/9/EC | Unauthorised extraction or reuse |
| Patent | Applicable national patent law | Depends on national characterisation of the clause |
What changes when a field-of-use limit is ignored
The practical difference lands in three places. First, the forum: an infringement claim can go straight to the court with jurisdiction over the right, while a contract claim often has to follow a dispute-resolution clause first. Second, the limitation period: it starts from the unauthorised use itself, not from the date the licence was signed. Third, the remedy: infringement opens the door to an injunction and to seizure of infringing stock; a bare contract claim gives damages only.
What to do, in order
- Freeze the record. Preserve the licence, the correspondence around the field-of-use clause, and evidence of the disputed use. Compliance team, immediately.
- Classify the clause. Establish whether it operates as a condition of the grant or as a separate covenant. Counsel, before any notice goes out.
- Map the use against the field. Document the channel, product line, and territory actually reached. Operations, with dated exhibits.
- Send a scoped notice. Name the specific use, the specific clause, and a response deadline — not a general breach letter. Counsel.
- Pick the forum before the licence's own deadline runs out. File the infringement claim or trigger the contractual mechanism, whichever the classification supports. Counsel.
- Preserve alternative claims. Plead contract and infringement together where the licence allows it, so a classification dispute does not close a route. Litigation counsel.
Who decides, and on what evidence
The forum follows the classification. A national court with jurisdiction over the IP right decides an infringement claim; the licence's own dispute clause — court or arbitration — decides a contract claim. Both decide on the same core evidence: the licence text, the field-of-use definition, and records of the use that crossed it. Neither forum accepts a statement of what was intended; both ask for what the licence says and what happened afterwards.
If the licence covers software, a trade mark, or a tokenised right
If the underlying right is an EU trade mark and the field-of-use clause is really a boundary between two coexisting marks, the ignored limit often surfaces first as a coexistence dispute rather than a plain breach. See A coexistence agreement is proposed trade mark what it costs to be wrong for how that boundary is drawn and policed.
If the licence covers a dataset or a model trained on licensed material, a field-of-use breach rarely stands alone — the licensor's first question is usually where the material came from. See When the training corpus has no provenance: what it costs to be wrong for the provenance side of the same dispute.
If the right is tokenised — a licence recorded against a minted token — a field-of-use breach and a dispute over who minted the token tend to arrive together. See When the creator disputes the mint in practice for how the two claims are usually kept apart.
What this page does not resolve
This page does not decide, for your licence, whether the field-of-use clause is a condition of the grant or a separate covenant — that turns on the exact wording and on the governing law chosen. It does not calculate damages or set a settlement figure. It does not replace a reading of the licence itself.
Field-of-use disputes sometimes pull in personal data alongside commercial evidence — usage logs, account records, access lists. If you are named in a report and personal data is part of the file, If you are named in a report overview explained covers that separate process.

Frequently asked questions
What is the first step when field-of-use limits are ignored?
Freeze the record and classify the clause. Establish whether the field-of-use limit is a condition of the grant or a separate contractual covenant before sending any notice — the classification decides which forum and which remedy are available.
Which deadline is already running?
The limitation period for an infringement claim starts from the unauthorised use itself, not from the date the licence was signed. If the licence has its own notice period for breach, that period runs in parallel and independently of the limitation period.
Who decides, and on what evidence?
A national court with jurisdiction over the right decides an infringement claim; the licence's own dispute clause decides a contract claim. Both look at the same record: the field-of-use definition in the licence and evidence of the use that crossed it.
