Field-of-use restrictions in data licenses explained

What is a field-of-use restriction in a data license?

A field-of-use restriction limits a licensee to a defined purpose. In a data license it says, in effect, "you may use these records for X and nothing else." For the kind of deal SourceX arranges, X is AI training and evaluation, and everything outside that field stays with the company. Owners who worry that a competitor will get hold of their records should read this clause first, because it is the main contractual fence around the data.

The legal footing is ordinary. Under 17 U.S.C. 201, a copyright owner can transfer or license rights in whole or in part, and any exclusive right can be owned separately. A license is therefore not all-or-nothing; the owner chooses which uses to grant. This is general information, not legal, tax or financial advice. Have your counsel review the actual wording.

How do field of use, permitted use and exclusivity differ?

These terms are often confused, so separate them before reading a draft.

Exclusivity is worth a second look. A deal that is exclusive for AI training for an agreed term means the company does not license the same records to another AI developer in that field during the term. It does not mean the company gives up the data: the company keeps ownership and keeps using its own records for its own business.

What does a good field-of-use clause contain?

Look for five things.

1. A positive definition of the field, in terms of AI training, evaluation and related testing, rather than a vague phrase such as "business purposes."
2. An express ban on resale, sublicensing and redistribution of the raw records, with limited exceptions for processors working for the buyer under equal terms.
3. A ban on using the records to compete directly with the company, for example to build a service that targets the company's own customers from its own data.
4. A statement that outputs, such as model weights, are not a vehicle for returning the underlying records, paired with a ban on extraction. The no-re-identification clause guide covers the model-output limb in detail.
5. Remedies: termination, injunction and a duty to delete when the term ends, to the extent technically possible.

The part that trips owners up is the gap between what a clause says and what a buyer can do with knowledge it already holds. A residuals term can blur the fence, so read what a residuals clause means before accepting one.

Illustrative example: a 120-person logistics software company

Illustrative and fictional. A logistics software company with 120 full-time employees at peak wants to license eight years of support tickets, engineering reviews and implementation notes. Its owner worries that a rival software vendor could end up with the material.

The field-of-use clause answers the worry in three layers: the buyer may only use the records to train and evaluate AI models; the buyer may not resell, publish or hand the records to anyone outside its bound processors; and the license is exclusive for AI training for the agreed term, so no second AI developer gets the same records in that field. The company's own counsel confirms that none of this reaches the company's product, brand or customer list, which stay untouched.

What a field-of-use clause cannot do

Be honest with owners about the limits.

• It restricts the buyer's contractual rights, not what a regulator will say about the underlying data. Personal data, health information, student records and confidential counterparty material each carry their own rules. For example, the way education vendors treat student records is covered in FERPA and EdTech vendors.
• It does not substitute for redaction. De-identification and redaction requirements are agreed with the company before any work begins.
• It binds only the parties to the contract and those who agree to equal terms in writing.
• It is not a guarantee against misuse; it is the basis for a remedy if misuse occurs.

Buyers have their own incentive to honor it. Training on data of unclear origin can create real consequences, as discussed in FTC algorithmic disgorgement and why buyers want licensed data.

What to say when an owner worries about competitors

Lead with the fence, then the control.

How rewards and attribution work for partners

Partners make introductions and give basic fit information only; they do not draft or negotiate terms. Partners earn 25% of the eligible platform fees SourceX actually collects from the referred company's licensing deals, capped at $100,000 per referred company. The reward is paid only after the buyer pays and SourceX receives its fee; an introduction, meeting or signed agreement alone does not trigger payment, and no reward is guaranteed. The reward is a share of SourceX's fee and is never deducted from what the company receives. Licensed professionals should check their own rules on referral fees and disclosure first.

A review checklist for the owner and counsel

• The field is defined by purpose (AI training and evaluation), not by a loose phrase.
• Resale, sublicensing and redistribution are prohibited, with named exceptions only.
• Direct competition using the raw records is prohibited.
• Exclusivity, term and territory are stated, with the exclusive field spelled out.
• Deletion or return happens on expiry, to the extent technically possible.
• The residuals wording does not undo any of the above.
• Redaction rules are attached to the agreement.

Next step

If you know an owner who has years of records and wants a fence around how they are used, register as a partner and make the introduction, or ask the owner to run the company fit checker first. The stages from introduction to payment are laid out in how SourceX referrals work. Companies can also apply directly at sourcex.si/apply.
