The IP due diligence checklist every investor should use

Advancii Team · 15 June 2026

For deep-tech and IP-heavy companies, the intellectual property is the investment. Yet IP due diligence is often the most rushed part of a deal. This checklist gives you a structured way to assess a target's IP before you commit capital - and to spot the red flags early.

1. Confirm ownership

Start with the most basic - and most frequently broken - question: does the company actually own its IP? Check that inventors and contractors have assigned their rights, that no university or prior employer has a claim, and that the chain of title is clean from invention to current owner.

2. Assess portfolio strength

Counting patents tells you almost nothing. Look at quality and coverage:

  • Are the claims broad and enforceable, or narrow and easy to design around?
  • Does protection cover the company's actual commercial markets?
  • How much term remains on the core assets?
  • Are key patents still in force, with renewals paid?

3. Check freedom to operate

Owning patents is not the same as being free to sell your product. A target can hold strong IP and still infringe someone else's. Confirm there's a credible freedom-to-operate position and no known blocking patents in the relevant markets.

4. Watch for red flags

  • Unassigned inventor rights or contractor disputes.
  • Core patents nearing expiry with no pipeline behind them.
  • Pending litigation or oppositions.
  • Protection that doesn't match where revenue actually comes from.
