License vs assignment of intellectual property: how a company keeps ownership of its data

The verdict: a license keeps ownership, an assignment gives it away

An assignment is a transfer: afterward, someone else owns the asset and the original owner keeps only what the agreement gives back. A license is permission: the owner keeps title and lets another party use the asset for a defined purpose, scope and period.

For a business owner asked about licensing company data, that distinction answers the most common objection: are we selling our data? In a SourceX deal the answer is no. The company grants a license, keeps ownership of its records, keeps using them to run the business and signs nothing until it accepts the price and terms. Whether a license is worth doing at all is a separate question, covered in is licensing company data worth it.

License vs assignment side by side

Plain examples

Three everyday comparisons make the difference concrete.

• Software: a business that pays for accounting software holds a license. The vendor still owns the code; the business uses it under the subscription terms.
• Property: a lease is close to a license and a sale is close to an assignment. The landlord keeps the building and collects rent; a seller hands over the keys for good.
• Music: a band that licenses a song to an advertiser still owns it and can license it to a film next year unless it agreed to exclusivity. A band that assigns its copyright to a publisher no longer controls the song.

Illustrative: a fictional 140-person engineering services firm holds twelve years of project files, design reviews and support tickets. If it assigned that archive, the buyer would own the records and could limit how the firm uses its own history. Under a license, the firm keeps the archive, keeps using it for proposals and staff training, and grants an AI developer the right to use a defined, redacted copy for AI training during an agreed term.

What the law allows: splitting rights without giving up ownership

US copyright law treats ownership as divisible. Under 17 U.S.C. 201, ownership of a copyright may be transferred in whole or in part, and any of the exclusive rights may be transferred and owned separately. That is the basis for granting one specific right, such as use for AI training, while keeping the rest.

Two cautions apply. First, an exclusive grant is a bigger commitment than a non-exclusive one and can carry legal consequences that look more like a partial transfer than a simple permission, so have counsel explain how the exclusive grant in a draft is treated. Second, not every business record is protected by copyright, so much of what a data license controls is set by the contract itself: field of use, confidentiality, redaction, delivery and what happens when the term ends.

Ownership also does not cancel promises. FTC staff wrote in January 2024 that companies' commitments not to use customer data for undisclosed purposes, such as training models, are enforceable whether they appear in privacy policies, terms of service or marketing materials. That is staff guidance rather than a rule, but the point stands: owning a record and being free to license it are different questions, and the company's counsel checks both.

This is general information, not legal, tax or financial advice. Confirm with your own counsel before signing any license or assignment.

Why SourceX deals are licenses, not sales

Every SourceX deal is built as a license:

• The company keeps ownership of its data; the data is licensed, not sold.
• The license is typically exclusive for AI training for an agreed term, and the agreement defines which records are in scope.
• Redaction and de-identification rules are written down with the company before anyone starts preparing records.
• Nothing binds the company until it agrees price and terms and signs, and no data moves until the agreement is executed and the company authorizes delivery.
• The company receives one all-in price as a one-time payment, with SourceX's fee included. One-time license fee vs royalty explains why that structure suits most mid-sized licensors.

Exclusivity is the term owners should weigh most carefully, because it stops the company from licensing the same data to other AI buyers during the term. The page on exclusive data license opportunity cost sets out how to think about it.

Clauses that signal which one you are signing

Read the grant clause first. The phrases below are common signals, not legal tests.

The owner's checklist before signing a data license

• The agreement says the company retains ownership of the records.
• The grant is limited to a stated field of use, such as AI training and evaluation.
• The term, any exclusivity and what exactly is exclusive are written out.
• The scope lists systems, date ranges and record types, with redaction rules attached.
• Confidentiality duties and permitted recipients are defined.
• End-of-term rules are clear, including what the licensee may retain.
• Nothing in the draft uses assignment language you did not intend.
• Counsel has checked the company's own commitments to customers and employees.

Before any of this, the company has to qualify. The baseline on who qualifies covers US companies that reached 50+ full-time employees at peak (contractors excluded), with several years of documented operations, rights to license the data and an authorized sponsor. The company fit checker gives a quick, non-binding read, and how much data a company needs covers volume.

What partners can say when an owner asks if they are selling their data

Keep it short and accurate.

Partners make the introduction only; they never handle, export or describe the records.
