Intellectual Property Ownership
What it means
An IP ownership clause decides who owns what gets created. In any agreement involving design, writing, code, branding or product development, it is usually the most valuable clause in the document.
The default rules are not intuitive. In many jurisdictions a contractor who creates something owns the copyright in it unless the contract says otherwise — which surprises clients who assumed that paying for work meant owning it, and surprises contractors who assumed they had sold everything.
Contracts resolve this in one of three ways. An assignment transfers ownership outright to the client, usually on payment. A work-made-for-hire provision treats the client as the author from the outset, though this only works for certain categories of work and often needs an assignment as a backstop. Or the creator keeps ownership and grants a licence, which may be exclusive or non-exclusive, perpetual or limited.
The part most often missed is pre-existing material. A developer's reusable component library, a designer's template system, an agency's internal tooling — these predate the engagement and typically should not transfer with it. A well-drafted clause carves them out and grants the client a licence to use them as embedded in the deliverable.
Also look for moral rights, and for whether the assignment is conditional on payment. An assignment that takes effect on signature rather than on payment means the client owns the work whether or not the invoice is settled.
Why it matters for your business
If you are buying, weak IP language can leave you unable to modify or resell what you paid for. If you are selling, broad language can hand over the reusable tooling that makes your business efficient, along with the specific deliverable.
