Background IP
Also called: Pre-Existing IP · Background Intellectual Property
Background IP is intellectual property a party already owned before the contract began — pre-existing tools, code libraries, frameworks, or know-how — as distinct from "foreground IP" created during the engagement. A contract's IP clause needs to treat the two very differently.
In more detail
A broad "all IP assigned to the client" clause, without a background IP carve-out, can inadvertently assign a service provider's own general-purpose tools and frameworks — the things they need to reuse on every other engagement — to a single client.
The standard structure grants the client ownership (or an exclusive licence) over foreground IP created specifically for them, while the provider retains ownership of background IP and grants the client only a licence to use it as embedded in the deliverable.
Disputes usually arise from ambiguity about which category something falls into — code adapted from an existing internal library sits in a grey zone between "pre-existing" and "created for this engagement" unless the contract defines the boundary clearly.
A development agency builds a client's app using its own pre-existing authentication framework. Without a background IP carve-out, an "all work product assigned to client" clause could be read as assigning the framework itself — preventing the agency from using it on any future client project.
What our lawyers check
- Whether background IP is defined and expressly carved out of the assignment
- What licence (if any) the client receives to use embedded background IP
- Whether the boundary between background and foreground IP is clear enough to avoid disputes
- Whether the provider retains the right to reuse general tools and know-how on other engagements
