IP Assignment Clauses: Five Things to Check Before You Sign
This page is general information, not legal advice.
An IP assignment clause transfers ownership of intellectual property from you to the other party. That can include code, designs, writing or inventions. These clauses appear in freelance contracts, independent contractor agreements and employment contracts. An assignment is hard to undo. Once you assign rights, you need the new owner's permission to reuse your own work. This page covers five versions of the clause that can transfer more than you expect. For each one you get an illustrative wording, why it matters and what to ask for instead. The example clauses were written for this guide and are not taken from any real company's contract.
Assignment vs license: the short version
An assignment transfers ownership. The client becomes the owner, and you keep only what the contract gives back to you. A license is permission to use the work. You stay the owner, and the client gets defined rights. A license can be exclusive or non-exclusive and can be limited by purpose, territory or time. If the client only needs to use a deliverable, a license may be enough. If they need to own it outright, for example to sell their business or register the rights, they will usually ask for an assignment. For licenses that never end, see perpetual content licenses explained.
1. Assignment of everything "related to" the business
A typical clause might read: "Contractor hereby assigns to Company all right, title and interest in any and all Work Product, meaning any materials, ideas, inventions or works conceived or developed by Contractor during the term of this Agreement that relate to Company's business."
Why it works against you
This clause is triggered by when you made something and what it's about, not by what you deliver. "During the term" and "relate to Company's business" can pull in side projects, work for other clients in the same industry, or tools you build on your own time. "Hereby assigns" can also mean the transfer of future work is agreed at signing, not at delivery. See independent contractor agreement red flags.
What to ask for instead
Sample wording to propose: "Contractor assigns to Company the deliverables specifically described in each Statement of Work and created for Company under this Agreement. Nothing in this Agreement assigns work created for other clients, or on Contractor's own time without use of Company resources."
2. Ownership passes before you are paid
A typical clause might read: "All Work Product shall be the sole property of Company upon creation."
Why it works against you
If ownership passes when the work is created, the client owns it even if the invoice is never paid. In a payment dispute, holding back the rights is often your strongest leverage, and this clause removes it. You may be left chasing a debt for work the client is already free to use.
What to ask for instead
Sample wording to propose: "Ownership of each deliverable transfers to Company upon Contractor's receipt of full payment for that deliverable. Until then, Company has a limited, non-exclusive license to review and test it."
3. "Work made for hire" plus a backup assignment
A typical clause might read: "All Work Product shall be considered 'work made for hire' to the extent permitted by law. To the extent any Work Product does not qualify as a work made for hire, Contractor hereby irrevocably assigns it to Company."
Why it works against you
"Work made for hire" is a US copyright concept. When it applies, the hiring party is treated as the author from the start, not as a later owner by transfer. It generally applies to work employees create within the scope of their job. For independent contractors, it covers only certain categories of commissioned work and requires a signed written agreement. That's why contracts add a backup assignment. Either way, you keep nothing unless the contract gives it back. The label can also matter later. In some cases US law lets authors who assigned their rights end the transfer years afterward, which generally isn't possible for works made for hire. In some places, calling a contractor's work "for hire" may also affect employment status. Ask a qualified lawyer how this applies to you.
What to ask for instead
Sample wording to propose: "Contractor is an independent contractor. Rights in the deliverables transfer by assignment on full payment as set out in this Agreement. Contractor keeps a non-exclusive right to show the deliverables in a portfolio after Company has made them public."
4. Prior inventions and background IP
A typical clause might read: "Contractor has listed in Exhibit A all prior inventions Contractor wishes to exclude from this Agreement. If no list is attached, Contractor represents that there are none. If Contractor incorporates any prior invention into Work Product, Company is granted a perpetual, irrevocable, worldwide, royalty-free license to use it."
Why it works against you
The trap is the blank exhibit. If you leave it empty, you are stating that you have no relevant prior work. That can make it harder to prove later that a code library, template or method was already yours. The license to prior work you include is usually perpetual, so a toolkit you reuse can end up licensed to every client. In employment contracts, some jurisdictions limit an employer's claim to inventions made entirely on your own time without company resources. These clauses often sit next to restrictive covenants, so see also non-compete clauses explained.
What to ask for instead
Sample wording to propose: "Contractor retains all rights in Background IP, including tools, code libraries, templates and know-how developed before or outside this Agreement. Where Background IP is incorporated into a deliverable, Company receives a non-exclusive license to use it solely as part of that deliverable."
Fill in the exhibit, even with general categories, rather than leaving it blank.
5. Moral rights waiver and power of attorney
A typical clause might read: "Contractor waives all moral rights in the Work Product and irrevocably appoints Company as attorney-in-fact to execute any documents necessary to perfect Company's rights."
Why it works against you
Moral rights cover things like being credited as the author and objecting to distortion of your work. Some countries protect them more strongly than others. A waiver can let the client remove your name or change the work freely. The power of attorney lets the client sign transfer documents in your name. A power of attorney is common, but it should apply only to this agreement's deliverables.
What to ask for instead
Sample wording to propose: "Company may sign documents on Contractor's behalf only for deliverables assigned under this Agreement, and only if Contractor fails to sign within 14 days of a written request. Company will credit Contractor where credits are customarily given."
Also worth a look
Check whether the assignment survives termination, which it almost always does. Check whether any wording stops you from using your general skills and experience, and whether you have a portfolio right. For creative work, see creative services contract red flags.
