IP Assignment Agreement

A signed agreement, from every founder, employee, and contractor who touches the product, assigning to the company any intellectual property they create in connection with the work — without it, the company may not actually own its own code and inventions.

Why does IP Assignment Agreement matter?

Without a signed assignment, work product created by a contractor or a pre-incorporation co-founder can legally belong to the person who wrote it, not the company — and this surfaces at the worst possible time, during diligence for a fundraise or acquisition, when a gap in the chain of ownership can stall or kill the deal. It is invisible risk until someone checks, which is precisely when an investor's lawyer will check.

What does IP Assignment Agreement look like in practice?

Suppose a technical co-founder builds the first version of the product for three months before the company incorporates, then a contractor is brought on to build a key integration before anyone thinks to send paperwork. If neither signed an assignment agreement, the company's cap table and product may both rest on IP it does not clearly own. Fixing it after the fact means tracking down the co-founder and contractor to sign retroactively — straightforward if relationships are good, a real obstacle if they are not, which is exactly the wrong time to find out.

What are the common mistakes with IP Assignment Agreement?

  • Treating it as an employee-only document and skipping it for contractors, advisors, or a co-founder who has not yet formally joined.
  • Signing it after the person has already started building rather than before or at the start of the engagement.
  • Assuming a general NDA covers IP ownership — it does not; assignment is a separate, specific grant.
  • Losing track of who has and has not signed as the team grows, discovered only when a due-diligence checklist asks for the full set.
