License Agreement

A license agreement is a contract in which the owner of intellectual property (IP) -- a patent, copyright, trademark, or trade secret -- (the licensor) grants another party (the licensee) permission to exercise specified rights in that IP, in exchange for agreed-upon consideration, without transferring ownership of the underlying IP itself. A given arrangement counts as a license agreement, rather than some other transaction, when three elements are present together: (1) the licensor retains title to the IP throughout the term of the agreement, (2) the grant is bounded -- limited by scope (which rights: make, use, sell, reproduce, display, etc.), field of use, territory, and/or duration -- rather than an unrestricted, permanent transfer of all rights, and (3) the agreement specifies the consideration and other obligations attached to the grant, typically royalties, an upfront or milestone fee, sublicensing terms, reporting requirements, and termination conditions. Because the licensor keeps ownership, a license agreement is legally distinct from an assignment, which transfers ownership of the IP itself to the assignee; the underlying grant can also be exclusive (only the licensee may exercise the granted rights, even excluding the licensor) or non-exclusive (the licensor may grant the same rights to other parties in parallel).

Worked examples

Is an instance

A university technology transfer office grants a pharmaceutical company an exclusive, worldwide license to make, use, and sell products covered by a university-owned patent on a drug-delivery compound, in exchange for an upfront fee, milestone payments, and running royalties on net sales -- the university retains title to the patent for the life of the agreement.

Is an instance

A software vendor grants a customer a non-exclusive, non-transferable license to install and use a specified number of copies of its software for internal business purposes, subject to an annual subscription fee -- the vendor retains all copyright and other IP rights in the software itself.

Looks similar, but isn't

Not an instance

A researcher signs an invention assignment agreement transferring all right, title, and interest in a patentable invention to their employer as a condition of employment. This is an assignment, not a license: ownership of the IP itself moves from the researcher to the employer, rather than the employer merely receiving permission to use IP the researcher continues to own.

A license agreement is the foundational legal instrument of technology transfer and IP commercialization: it is how a patent, copyrighted work, trademark, or trade secret gets put to productive use by someone other than its owner, without that owner giving up title. Universities, research institutions, and companies rely on license agreements constantly — from a technology transfer office (TTO) licensing a patented invention to a startup, to a publisher licensing reuse of a copyrighted figure, to an end user clicking through a software license agreement.

The core structure: a bounded grant, not a transfer

Every license agreement grants specified rights within defined limits rather than handing over the IP itself. The boundaries typically negotiated include:

Scope of rights — which of the IP owner’s exclusive rights are being granted (for a patent: make, use, sell, offer for sale, import; for a copyright: reproduce, distribute, display, create derivative works; for a trademark: use the mark in connection with specified goods/services).
Exclusivity — whether the licensee is the only party permitted to exercise the granted rights (exclusive), one of several parallel licensees (non-exclusive), or the sole licensee while the licensor itself retains the right to practice the IP (sole license).
Field of use — the specific application or market the license covers (for example, a patent on a compound might be licensed for therapeutic use in oncology but not for agricultural applications, allowing the licensor to license the same patent separately in other fields).
Territory — the geographic scope of the grant.
Term — how long the license lasts, and whether it can be renewed, converted (e.g., from exclusive to non-exclusive on missed milestones), or terminated early.
Consideration — what the licensee pays: an upfront fee, milestone payments, running royalties on sales, minimum annual royalties, or some combination.

For the full clause-by-clause anatomy of these terms — grant language, royalty structures, sublicensing, warranties, and termination — see CASRAI’s guide to license agreement structure and the accompanying worked license agreement template.

License agreement vs. assignment

The distinction between a license and an assignment is the single most consequential fact about a license agreement, because it determines who owns the IP going forward:

In a license, the licensor keeps title to the IP. The licensee receives permission to exercise specific rights for a specific period, and those rights typically revert to the licensor (or simply lapse) when the license ends.
In an assignment, ownership of the IP itself transfers to the assignee, permanently and completely (unless the assignment is itself limited in scope, which is less common). The assignor has no residual rights to license the same IP to someone else afterward.

This distinction matters throughout the research lifecycle. Under the Bayh-Dole Act, a university that elects to retain title to a federally funded invention almost always commercializes it through a license to an outside company or spinout, not an assignment — retaining title lets the institution continue to meet Bayh-Dole’s ongoing obligations (such as march-in rights and the statutory preference for U.S. manufacturing) and, in many cases, generate ongoing royalty revenue rather than a single one-time payment. By contrast, an employee inventor typically executes an assignment (not a license) of their rights to their employing institution, precisely because the institution needs to hold clean title before it can, in turn, license the invention out.

What a license agreement is not

A license agreement is not a sale of goods, a service contract, or a non-disclosure agreement, though real-world deals often combine a license with these other elements (a sponsored research agreement, for instance, may include a license grant to background IP alongside its research-services terms). A license agreement is also distinct from a mere permission or waiver that isn’t tied to a specific IP right — what makes a document a license agreement, as opposed to some other kind of contract, is that its operative clause grants rights in identified IP, in exchange for consideration, while ownership stays put.
