How much does IP due diligence cost in an M&A deal?
Updated June 2026
The short answer
Published estimates put IP due diligence for mid-market M&A deals commonly at $15,000 to $50,000, with large or IP-centric transactions running well into six figures. The drivers are portfolio size, how central the IP is to the deal thesis, and how much independent verification the buyer needs beyond a document checklist.
When the target's value rests mainly on its technology, IP diligence carries the deal analysis, and the budget should reflect that rather than being set as a fixed small fraction of legal spend.
What IP diligence actually covers
The full scope has seven layers: ownership and chain of title; encumbrances, meaning licenses out, liens, joint development agreements, and government rights; whether the portfolio actually covers the products generating the revenue being bought; validity exposure on the crown-jewel assets; a freedom-to-operate overlay where the buyer plans to expand the product; trade secret hygiene, since undocumented secrets transfer badly; and open source compliance for software targets.
Few deals need every layer at full depth. The first scoping task is deciding which layers the deal thesis actually depends on, because that decision sets most of the budget.
What moves the cost
Portfolio size and asset mix come first: fifty US patents review faster than four hundred families across nine jurisdictions plus trademarks and trade secrets. Depth comes second, and it is a real choice: confirming documents exist is one price, independently assessing whether the patents are any good is another, and a full valuation is a third. Timeline compression is the quiet multiplier, because exclusivity windows force workstreams to run in parallel with more people.
Seller preparation moves the number too. Sell-side IP reviews ahead of a process are increasingly common, and they are usually money well spent: problems found by the seller get fixed, while problems found by the buyer get priced.
Legal diligence and business diligence are different workstreams
Counsel verifies the legal facts: title, assignments, encumbrances, and litigation history. That work is legal practice and belongs with lawyers. The business questions, whether the portfolio is high quality, whether it covers the revenue, how it compares to competitors, and what it is worth, are consulting work, and they are the questions that decide whether the deal price makes sense.

Related questions
Who pays for IP due diligence?
The buyer pays for its own diligence. Sellers commonly fund sell-side readiness work before going to market. Both sides are buying the same thing: fewer surprises inside the exclusivity window, when surprises are most expensive.
Is a valuation included in due diligence?
They are adjacent but distinct. Diligence asks whether the IP is what the seller claims; valuation asks what it is worth. Many deals need both. At ipCG, valuation built for M&A support typically starts at $50,000 and is scoped to survive the other side's scrutiny.
How long does IP diligence take?
Typically 2 to 6 weeks, governed mostly by portfolio size and how quickly the seller produces documents. We cover the timeline question in detail on a separate page.
What happens when diligence finds problems?
The common outcomes are price adjustments, escrows or holdbacks, closing conditions requiring fixes such as recording missing assignments, or in serious cases walking away. The earlier a problem surfaces, the more of those options remain open.
