IP Assignment vs IP Licence: the Difference (2026)

IP assignment vs IP licence: the short answer The difference is about ownership. - An assignment transfers ownership of the intellectual property (IP) from one party to another. After an assignment, the new owner holds the rights, and the original owner has given them up (fully or in part).

• A licence keeps ownership where it is and grants permission to use the IP on agreed terms. After a licence, the owner still owns the IP; the licensee only has the right to use it within the limits of the licence. Put simply: assignment is selling the house; a licence is renting it. One changes who owns the asset; the other only grants use. This article is general guidance, not legal advice. IP law varies by jurisdiction and by type of right, so take professional advice before signing an assignment or a licence. ## What an assignment does An assignment moves the IP from the assignor to the assignee. It can be: - Full or partial. You can assign all the rights, or only some, for example one type of right, one territory, or one period.
• Permanent. Once assigned, the rights belong to the new owner, subject to any terms in the deed. Assignments usually need to meet formalities. For copyright, most jurisdictions require the assignment to be in writing and signed by the owner; an oral assignment generally does not work. For patents and registered trade marks, an assignment is usually recorded on the relevant register to be effective against third parties. ## What a licence does A licence grants permission to use the IP while the owner keeps title. Key choices in a licence: - Exclusive, sole or non-exclusive. An exclusive licence lets only the licensee use the IP, even to the exclusion of the owner. A sole licence lets the owner and one licensee use it. A non-exclusive licence lets the owner grant the same rights to many.
• Scope. The licence sets the permitted uses, the territory, the field of use, the term, and whether the licensee can sub-license.
• Royalties. A licence commonly involves ongoing payments, unlike a one-off assignment price. Because the owner keeps title, a licence can be limited, time-bound and revocable in ways an assignment is not. ## Side by side | Feature | Assignment | Licence | |---|---|---| | Ownership | Transfers to the assignee | Stays with the owner | | Nature | Usually permanent | Can be time-limited and revocable | | Payment | Often a one-off price | Often ongoing royalties | | Control after the deal | Assignor loses control | Owner keeps control and can set limits | | Typical formality | Written, signed; registered for patents/marks | Written; terms set the scope | | Best when | You want the rights to change hands for good | You want to keep ownership but allow use | ## When to use which - Use an assignment when the rights really need to change hands: a founder assigning IP into a company, an acquirer buying a product's IP, or a client who must own what a contractor builds.
• Use a licence when the owner wants to keep the asset but let others use it: software sold to customers, a brand licensed to a partner, or a patent licensed to a manufacturer. A common hybrid is an assignment with a licence back, where the creator assigns the IP but keeps a licence to use it for limited purposes. ## Jurisdiction notes The assignment-versus-licence distinction exists everywhere, but the formalities differ by jurisdiction and by right. - India. Under the Copyright Act, 1957, an assignment must be in writing and signed by the owner (Section 19), and an oral assignment is not valid. Section 19 also sets defaults: if no duration is stated it is deemed five years, and if no territory is stated it is presumed to be India. Rights the assignee does not use within one year can lapse. Certain author royalty rights cannot be signed away. Section 30 allows licences, and Section 30A applies the Section 19 mechanics to licences, so a copyright licence must also be in writing and signed. Patents and trade marks have their own assignment and registration rules under the Patents Act, 1970 and the Trade Marks Act, 1999.
• Other jurisdictions. In the UK, US, Singapore and Australia, copyright and registered-right assignments generally need to be in writing and signed, and registered patents and trade marks are recorded on a register. The precise defaults, registration effects and author protections differ, so the deed should be drafted for the jurisdiction and the type of IP involved. ## Negotiation points, for both sides For the party acquiring rights: decide whether you truly need ownership (assignment) or only use (licence). If assigning, make sure the deed is in writing, signed, covers all relevant rights and territories, and includes a waiver of moral rights where the law allows and a warranty of ownership. If licensing, pin down exclusivity, scope, term, sub-licensing and what happens on termination. For the party giving up rights: if assigning, consider a licence back for your own continued use, and check which author or moral rights you cannot and do not want to waive. If licensing, keep the scope tight, reserve everything not granted, and set clear royalty and audit terms. ## Where a contract workspace helps Assignment and licence terms are scattered across many contracts: contractor agreements, SaaS terms, brand deals, employment contracts. The risk is in the detail, such as a licence that should have been an assignment, or an assignment missing the written-and-signed formality a court will require. Keeping these terms consistent and checking them before signing is contract work. Drafting, reviewing, tracking and governing the assignment and licence clauses scattered across all those agreements can sit in one AI workspace tuned to how your company handles IP, which flags a missing assignment formality or an over-broad licence as you go. Adira is built along these lines. This explainer alone is enough to tell an assignment from a licence; a single workspace just makes the drafting, review and tracking one connected job rather than several scattered ones.
