What Is an IP Assignment Clause?
An IP assignment clause transfers ownership of intellectual property — designs, code, writing, inventions — from the person who created it to the other party, typically the client or employer. In client work this is normal; the contract's job is to say what transfers and, critically, when.
Why it matters
For anyone who creates work for clients, IP assignment timing is leverage. If ownership transfers the moment work is created, the client owns everything even if they never pay. If it transfers upon full payment, your ownership is the reason invoices get paid. The scope matters too: a broad assignment can sweep in the reusable tools and templates you brought with you.
What to watch for
- Assignment "upon creation" or "regardless of payment."
- No carve-out for pre-existing materials — your frameworks, snippets, and templates (your background IP) get assigned along with the deliverables.
- No portfolio right: you can't show the work you made.
- Moral-rights and future-invention language that reaches beyond the project.
A realistic example
A copywriter delivers a brand campaign under a contract assigning all IP on creation. The client disputes an unrelated invoice line and stalls payment for months — while already running the campaign. Because ownership has transferred, the copywriter's strongest lever (withholding the license until payment) is gone.
What to ask for
- Conditional transfer: "All IP in the deliverables transfers to the Client upon receipt of full payment."
- A background-IP carve-out: pre-existing tools and know-how stay yours, licensed to the client as needed for the deliverables.
- A portfolio license to display the finished work.
