What is IP Assignment?
IP assignment (intellectual property assignment) transfers ownership of creative work from the creator to the client. Learn why IP assignment clauses matter in freelance contracts and how to negotiate fair terms.
What Is IP Assignment?
IP assignment (intellectual property assignment) is a contract provision in which one party (the creator/freelancer) transfers ownership of intellectual property rights — copyright, patents, trademarks, trade secrets — to another party (the client). The key concept: just because you create something for a client doesn't mean they own it. Under U.S. copyright law (and most countries' copyright law), the creator owns the copyright to their work by default. IP assignment is how that ownership is formally transferred. Without an explicit IP assignment clause in your contract, you may retain copyright to everything you create for the client — even after they pay your invoice.
Why IP Assignment Matters for Freelancers
Consider this scenario: You design a logo for a client, send the final files, and they pay your $2,500 invoice. Six months later, you see your logo design on a major brand's website — it's the same concept you created, but rebranded. You ask the client about it, and they say: "We paid for it. It's ours now." Are they right? Only if your contract included an IP assignment clause. Without an assignment clause, you — not the client — own the copyright to the logo. They licensed it, but they don't own it. They can't use it in ways you didn't authorize.
What IP Can Be Assigned?
| Type | What It Covers | Example | |---|---|---| | Copyright | Original creative works | Photos, writing, designs, code | | Patent | Inventions and processes | New products, methods | | Trademark | Brand identifiers | Logos, brand names, slogans | | Trade secrets | Confidential business info | Formulas, customer lists | | Database rights | Organized data collections | Compiled information | Most freelance work involves copyright assignment — transfer of rights to creative works.
IP Assignment Clause Language
A typical copyright assignment clause looks like: > "Contractor hereby irrevocably assigns to Client all right, title, and interest in and to the Deliverables, including all copyrights, trademarks, and other intellectual property rights therein, throughout the world, in perpetuity. Contractor agrees to execute any documents reasonably requested by Client to perfect Client's ownership of such rights." Key Elements 1. Scope of assignment — What specifically is being assigned (Deliverables, all works, specific items)? 2. Rights being assigned — Copyright only? All IP? Worldwide? 3. Timing — When does the assignment take effect (upon payment, upon creation, upon delivery)? 4. Consideration — What are you being paid for the assignment? 5. Supporting obligations — Will you sign additional documents if needed?
IP Assignment vs. IP License
| | Assignment | License | |---|---|---| | What it does | Transfers ownership | Grants permission to use | | Who owns it after | Client owns it | You still own it | | Scope | Full transfer | Limited, defined by license terms | | Revocability | Irrevocable (typically) | Can be limited (exclusive) or revocable (non-exclusive) | | What you get paid | Full value of the work | Usually less than full assignment | Exclusive license is almost as powerful as assignment — the client can use it exclusively, and even you can't use it. But you technically retain ownership.
Negotiating IP Assignment
Standard (Client-Favored) Position > "Contractor assigns all rights in all deliverables, worldwide, in perpetuity." This is what most big-company contracts say. It's the most restrictive for freelancers. Freelancer-Friendly Negotiation Points 1. Retain portfolio rights — You can show the work in your portfolio 2. Pre-existing materials — Tools, frameworks, code libraries you built before this engagement aren't included 3. Sublicensing rights — You retain rights to use the work in your own marketing 4. Kill fee on IP — If client terminates early, you get paid AND retain IP 5. Escrow for source code — In software, source code is held in escrow until payment Example: Negotiated IP Clause > "Contractor assigns to Client all copyrights in the Deliverables for use in Client's business. Contractor retains the right to display the Deliverables in Contractor's portfolio and marketing materials. Contractor retains all rights in Contractor's pre-existing tools, frameworks, and methodologies."
Work Made for Hire
Another important concept: Work Made for Hire (WMFH). Under U.S. copyright law, work created by an employee is owned by the employer by default. For freelancers (independent contractors), WMFH only applies to specific categories of works AND only if there's a written agreement. Categories of WMFH for contractors: 1. Contribution to a collective work 2. Part of a motion picture or other audiovisual work 3. Translation 4. Supplementary work (foreword, illustration, etc.) 5. Compilation 6. Instructional text 7. Test or answer material for a test 8. Atlas For most freelance work — logos, websites, writing — WMFH doesn't automatically apply. You need an explicit assignment clause.
The Bottom Line
IP assignment transfers ownership of your creative work to the client. Without it, you may retain copyright even after payment. Read every IP assignment clause carefully, negotiate for portfolio rights and pre-existing material exceptions, and never accept a blanket "all IP, worldwide, in perpetuity" clause without understanding what you're giving up.
