Field-of-use drafting: documents to prepare
Field-of-use drafting fixes the boundary of what a licensee may do with the licensed IP — which product, market, or technical layer the grant reaches. Before drafting starts, three items must exist: an asset list, a boundary description written by the business side, and a decision on exclusivity. Missing any one of the three sends the clause back to draft zero.
What changes once the boundary is fixed
A field-of-use clause is not decoration. It sets what a licensee can rely on and what a licensor can still license to someone else in a neighbouring field. Get the boundary wrong and two outcomes follow: the licensee under-uses rights it paid for, or the licensor accidentally grants overlapping rights to two parties in the same field. Both outcomes surface later, usually at renewal or at the first sign of competing use — rarely at signature.
Timing depends on how many assets sit inside the boundary and how many business units need to agree on where it runs. A single-patent, single-market clause can close within a week. A multi-jurisdiction technology licence with several product lines routinely takes four to eight weeks, most of it spent aligning the business description with what the asset register actually covers.
Documents to prepare
| Document | Purpose | Prepared by |
|---|---|---|
| IP asset register | Lists every patent, mark, design, or copyright work the field will touch | IP team |
| Field boundary memo | Describes the product, market, or technical layer the licence will cover | Business owner |
| Draft licence with field-of-use clause | Converts the boundary description into binding contract wording | Drafting counsel |
| Use-case test scenarios | Checks the clause against edge cases before either side signs | Both parties |
| Signature authority list | Confirms who may bind each side and at what stage the grant becomes final | Legal or compliance |
What to do
- The IP team compiles the asset register first, before any drafting begins.
- The business owner writes the field boundary memo in plain commercial language, not legal wording.
- Drafting counsel turns the memo into a clause and cross-checks every asset against the register.
- Both parties run the use-case scenarios against the draft clause and flag anything the wording does not cover.
- The signatory on each side confirms authority and checks the point-of-no-return terms — irrevocability, minimum term, or exclusivity lock-in — before execution.
- Records staff file the executed licence together with the asset register it relies on, not as separate documents.

Who decides
Field-of-use boundaries are set by the parties, not by a regulator. There is no filing, no registry entry, and no approval step. If a dispute over scope arises after signature, it goes to whatever forum the licence names — an arbitration panel or a named court — and is decided against the wording of the clause itself, not against an external standard.
If your situation differs
If the licensed asset includes a registered trade mark used inside the field, the boundary should also state how distinctiveness in that segment will be shown if the mark is challenged later — see evidence of acquired distinctiveness for what a decision-maker looks at.
If the field spans design files produced through an outside agency — common in biotech and life-sciences work — confirm who owns those files before the boundary is drafted, not after. The ownership gap is described in biotech and life sciences an agency keeps the design.
If neither side has agreed a dispute-resolution forum yet, add that clause before the field-of-use clause, not after it. A boundary without an enforcement route is a description, not a contract term.
What this page does not cover
This page covers drafting mechanics only: which documents exist, who prepares them, and in what order. It does not cover how a licence fee is set, how royalties are calculated, or how a field-of-use dispute is escalated once it starts — that sequence is a separate procedure. It also does not cover national filing requirements, since those vary by asset type and jurisdiction and sit outside a drafting checklist.

FAQ
How long does field-of-use drafting take in practice?
A single-asset, single-market clause can close within a week. Multi-jurisdiction technology licences with several product lines usually take four to eight weeks, mostly spent reconciling the boundary memo against the asset register.
Which documents are needed to start?
An asset register and a field boundary memo. Without both, drafting counsel has nothing stable to convert into contract language, and the clause will be rewritten once the missing document appears.
What happens if the other side does not respond?
Drafting stalls at whichever step required their input — usually the boundary memo or the use-case test. Set a response deadline in the initial correspondence, and treat silence past that deadline as a signal to escalate through the forum named in any existing framework agreement, or to pause the deal.

What happens next
A field-of-use clause rarely stands alone for the life of the licence. If the licensed portfolio is later pledged as security, the field boundary becomes a term a lender will scrutinise — see when a portfolio is pledged to a lender: what to do first.
If prior art surfaces against a patent inside the field after grant, the boundary you drafted may need to be renegotiated around a narrower asset — the cost of that scenario is set out in what it costs to be wrong in this situation.
If the licensed asset touches tokenised rights and the creator later disputes the mint itself, the field-of-use clause will not resolve that dispute on its own — see when the creator disputes the mint: what to do first.
