Intangible Assets in M&A Due Diligence
Intangible Asset Masterclass — Lesson 9 of 10
When a private equity firm or strategic acquirer evaluates a target company, the due diligence process traditionally focuses on financial performance, legal compliance, and operational capability. Intangible asset due diligence — a systematic assessment of the intellectual property, customer relationships, technology, data, brand, and human capital that actually drive the target's value — is a more recent addition to the M&A toolkit. But it is rapidly becoming the most important dimension of the process.
This lesson covers the complete intangible asset due diligence framework: what acquirers assess, what sellers should prepare, how intangible asset quality affects deal structure and pricing, and the common red flags that trigger valuation discounts or deal restructuring.
In knowledge-intensive businesses, intangible assets typically represent 60-90% of enterprise value, yet intangible asset due diligence receives a fraction of the attention given to financial and legal review. Acquirers who conduct rigorous intangible asset DD identify value drivers, concentration risks, and protection gaps that materially affect deal pricing. Sellers who prepare their intangible assets for scrutiny — documenting, protecting, and measuring them before going to market — achieve higher valuations and smoother transactions.
The Due Diligence Framework
Intangible asset due diligence operates across five dimensions. Each dimension maps to the asset categories covered in Lessons 1-6 and the valuation methods from Lesson 7.
The Five Dimensions of Intangible Asset DD
| Dimension | Key Questions | Primary Assets Assessed |
|---|---|---|
| IP and Legal | Does the target own its core IP? Are protections current? Any infringement exposure? | Patents, trademarks, copyrights, trade secrets, domain names |
| Customer and Revenue | How concentrated is revenue? What are retention rates? Are contracts transferable? | Customer relationships, contracts, backlog, brand |
| Technology and Data | Is the technology stack modern and scalable? Is data unique and protected? | Software, databases, algorithms, platform technology |
| Human Capital | Who are the key people? What is attrition risk? Are there non-competes? | Assembled workforce, key person dependencies, organizational capital |
| Strategic and Synergy | Does the intangible asset base complement the acquirer's? Where are the synergies? | Cross-selling opportunity, technology integration, brand combination |
IP and Legal Due Diligence
The IP due diligence workstream is typically the most structured because it deals with assets that have formal legal documentation.
IP Due Diligence Checklist
1. Ownership verification
Confirm that the target entity (not its founders, employees, or contractors) owns all core IP. Review assignment agreements, employment contracts with invention clauses, and contractor IP assignments. Gaps here are deal-breakers — an acquirer cannot rely on IP it does not clearly own.
2. Registration and maintenance status
Review all patent filings, trademark registrations, and domain registrations. Verify that maintenance fees are current, renewal deadlines are tracked, and registrations cover all relevant geographies.
3. Freedom to operate
Assess whether the target's products or services infringe third-party IP. Review any existing licensing agreements, litigation history, cease-and-desist correspondence, and third-party patent landscape in the target's technology domain.
4. Open-source compliance
For technology companies, review the open-source software used in the product. Certain open-source licences (GPL, AGPL) impose copyleft obligations that could restrict the acquirer's ability to commercialise the software. Scan the codebase using automated tools.
5. Trade secret inventory
Request a trade secret register (if one exists). Assess the adequacy of protective measures: NDAs, access controls, security protocols, and departure procedures for employees with access to sensitive information.
