IP Ownership
An IP ownership clause decides who owns the intellectual property that each party brings to the contract and that is created while performing it.
What it does
Intellectual property (IP) covers copyright in software, documents, and designs, as well as patents, trade marks, database rights, and know-how. When a supplier builds or writes something for a customer, ownership of the result does not automatically pass to the customer. In many jurisdictions, the creator owns the copyright unless it is assigned in writing. The IP clause settles this by agreement.
Most clauses split IP into two categories. Background IP is what each party already owned before the contract or develops independently of it: the supplier’s platform, tools, and libraries, the customer’s brand and data. Background IP stays with its owner. Foreground IP (or deliverables) is what is created specifically under the contract. The clause decides whether this is assigned to the customer, retained by the supplier with a licence to the customer, or shared.
The clause usually also covers moral rights, improvements to background IP, and the supplier’s right to reuse general know-how on other projects.
Example wording
Each party retains all rights in its Background IP. The Supplier assigns to the Customer, with full title guarantee and upon payment of the applicable fees, all intellectual property rights in the Deliverables created specifically for the Customer under this Agreement, excluding any Background IP incorporated in them. The Supplier grants the Customer a non-exclusive, perpetual, royalty-free licence to use such Background IP to the extent necessary to use the Deliverables.
Risks for SMBs
You paid for it, but you do not own it. An SMB that commissions a website, software, or design and assumes ownership follows payment is often wrong. Without an express assignment, the developer may retain ownership and the customer holds, at best, an implied licence of uncertain scope. That matters when you change supplier, sell the business, or want to stop the supplier reusing the work.
Assigning away your platform. On the supplier side, a broad “all IP created under this Agreement belongs to the Customer” clause can hand over ownership of code that also runs your product for every other customer. Define background IP carefully and exclude it from any assignment.
Formalities. In many jurisdictions an assignment of copyright must be in writing and signed, and some rights, such as moral rights, cannot be assigned at all, only waived. This is jurisdiction-dependent. An assignment that is not properly executed may fail.
Employees and contractors. A supplier can only assign what it owns. If it used freelancers who never assigned their rights to it, the chain of title is broken. Ask for a warranty that the supplier owns or has cleared all rights in the deliverables.
Open source and third-party components. Deliverables often include code or assets under third-party licences that cannot be assigned. Require disclosure of these components and their licence terms.
Common variants and negotiation points
- Assignment on payment. A common middle ground is that IP in deliverables passes to the customer only when the relevant fees are paid in full, protecting the supplier against non-payment.
- Licence instead of assignment. Where the supplier needs to reuse the work, a broad, perpetual, irrevocable licence to the customer may satisfy both sides without transferring ownership.
- Know-how carve-out. Suppliers should retain the right to use general skills, techniques, and ideas learned on the project, provided no confidential information of the customer is disclosed.
- Improvements. Decide who owns improvements to background IP. Commonly the background IP owner owns them, with a licence back if needed.

- Confidentiality: protects know-how and unregistered information that IP rights do not cover.
- Indemnification: the IP infringement indemnity backs the ownership warranty.
- Subcontracting: where chain-of-title problems usually start.
