A copyright license is permission to use someone’s copyrighted work without that use being infringement. The owner keeps the copyright and hands over a defined slice of it. Royalties are the money that flows back under that grant, and with a narrow set of statutory exceptions, the rate is whatever the two sides agreed to. Copyright law supplies the rights and the formalities; the contract supplies the price.
The whole subject rests on one structural fact. Section 106 of the Copyright Act does not give an owner a single blob of “copyright.” It gives a bundle of separate rights: reproduction, derivative works, distribution, public performance, public display, and digital audio transmission of sound recordings. Section 201(d)(2) says any one of those rights, or any subdivision of one, can be transferred and owned separately. That divisibility is why licensing exists as an industry rather than as a sale.
An exclusive license promises that nobody else will exercise the licensed right, including the owner. An exclusive North American hardcover license means the publisher is the only entity on earth allowed to make North American hardcovers, and the author cannot compete with it.
The Copyright Act treats that as a transfer of copyright ownership. Section 101’s definition of “transfer of copyright ownership” expressly includes an exclusive license and expressly excludes a non-exclusive one. That definitional line triggers 17 U.S.C. § 204(a): a transfer is not valid unless it is in a writing signed by the owner or the owner’s duly authorized agent. No signed writing, no exclusive license, no matter how much money changed hands or how clearly both sides intended it. The exclusive licensee also gets something a non-exclusive licensee never gets: standing under § 501(b) to sue infringers of the licensed right in its own name.
A non-exclusive license is the opposite in every respect. The owner may grant the identical right to a hundred other people. It is not a transfer, so § 204(a) does not apply, and it can be created orally or implied entirely from conduct. The canonical case is Effects Associates, Inc. v. Cohen, 908 F.2d 555 (9th Cir. 1990), where a filmmaker commissioned special effects footage, paid most of the invoice, and got sued when he used it. The Ninth Circuit held the effects house had granted an implied non-exclusive license by creating the footage at the client’s request and handing it over knowing what it was for. The unpaid balance was a contract problem, not a copyright problem.
That case is the practical warning behind most licensing disputes. Casual arrangements do not fail to create rights. They create the weakest possible version of them, usually not in the direction the person who did the work intended.
Because the § 106 bundle is divisible, a license is best read as a set of boundaries rather than a yes or no:
Exceed those boundaries and the analysis forks. Breaching a condition of the license puts you outside the grant and makes you an infringer, exposed to statutory damages and an injunction. Breaching a mere covenant leaves you licensed and liable only for breach of contract. That distinction, sharpened in Jacobsen v. Katzer, 535 F.3d 1373 (Fed. Cir. 2008), is why open-source licenses are drafted so carefully around the word “provided that.”
In a few places Congress decided private bargaining fails, and it created licenses the owner cannot refuse:
Rates for these are set by the Copyright Royalty Board, three judges housed at the Library of Congress, in contested proceedings or approved settlements. In the Phonorecords IV proceeding covering 2023 through 2027, the headline streaming mechanical rate escalates from 15.1 percent of a service’s U.S. revenue in 2023 to 15.35 percent in 2027, subject to alternative all-in calculations.
The Music Modernization Act of 2018 rebuilt the § 115 license for streaming. Instead of song-by-song notices, digital services now get a blanket license administered by the Mechanical Licensing Collective, which launched in January 2021, maintains the public database of song ownership, collects the money, and holds unmatched royalties for later claiming. Services that use it gain a safe harbor from the statutory damages that had produced serial class actions.
The public performance right in musical works is administratively impossible to clear one song at a time. A bar cannot negotiate with every songwriter whose work its jukebox might play. Performing rights organizations solve this by aggregating repertoires and selling a blanket license: pay one fee, play anything in the catalog.
ASCAP and BMI, the two largest, have operated since 1941 under Justice Department antitrust consent decrees. Those decrees require them to license anyone who asks on non-discriminatory terms and, critically, send fee disputes to a rate court in the Southern District of New York rather than letting the PRO name its price. The DOJ closed its most recent review in January 2021 without proposing modifications, so the decrees remain in force. SESAC and Global Music Rights are not bound by them, which is why their negotiations with broadcasters have periodically gone to litigation instead.
Outside the compulsory licenses, the rate is pure contract. The recurring structures:
Two contract terms matter more than the headline number: the audit right, and reversion. Without an audit clause you cannot check the statement. Without reversion, an exploited-and-then-shelved work sits with a licensee who has no reason to use it.

What is a copyright license? A copyright license is permission from the owner to use one or more of the exclusive rights in 17 U.S.C. § 106 without the use being infringement. The owner keeps the copyright and grants a defined slice of it: a specific right, medium, territory, and term. A royalty is the money that flows back under that grant, and it is a contract term, not something copyright law itself sets outside the compulsory licenses.
What is the difference between an exclusive and a non-exclusive license? An exclusive license promises that nobody else, including the owner, may exercise the licensed right. It counts as a transfer of copyright ownership under § 101, so § 204(a) requires a signed writing or it is void. A non-exclusive license lets the owner grant the same right to as many people as it likes, is not a transfer, and can be created orally or implied from conduct.
Do you need a written contract for a copyright license? For an exclusive license, yes. Section 204(a) makes any transfer of copyright ownership invalid unless it is in a writing signed by the owner or the owner’s authorized agent. A non-exclusive license needs no writing and courts routinely find one implied from conduct, as in Effects Associates v. Cohen, where a filmmaker who commissioned and paid for special effects footage got an implied license to use it.
How are copyright royalties calculated? It depends on the deal. Common structures are a per-unit rate, a percentage of revenue or of net receipts, a flat buyout, or an advance recouped against future earnings. Compulsory licenses are the exception where a rate is set by law: the Copyright Royalty Board set the § 115 streaming mechanical headline rate escalating from 15.1 percent of service revenue in 2023 to 15.35 percent in 2027.

The Second Circuit held that ASCAP's consent decree forbids music publishers from selectively pulling their performance rights out of the collective for digital services like Pandora.
The Supreme Court held that publishers cannot resell freelance articles to electronic databases under the Section 201(c) collective-works privilege without the authors' permission.
