Why IP problems kill M&A deals

When an acquirer buys a tech company, they are buying the IP. Everything else — the team, the customer contracts, the revenue — is secondary to the question of whether the company actually owns what it claims to own. Most founders discover their IP is messier than they thought during diligence, not before it.
🔍
Three reasons IP issues surface in M&A — always at the wrong moment
Why the problem is structural, not accidental
3 reasons
1
Founders build fast and document slowly
Early-stage companies hire freelancers, onboard contractors, and integrate open source libraries under time pressure. IP assignment agreements get deferred, open source inventories never get done, and employment contracts use template language that was not reviewed by a lawyer. None of this matters until someone asks for the documentation.
In M&A diligence, someone always asks. The question is whether the answer takes 2 days or 6 weeks — and whether the answer is reassuring or alarming.
2
Offshore development creates structural IP gaps
IP assignment rules differ by jurisdiction. In many countries, a contractor who writes code owns that code by default — an employment contract or service agreement without an explicit IP assignment clause does not transfer ownership to the company. If you built your product with developers in Eastern Europe, India, or Southeast Asia on standard service contracts, there is a real chance significant portions of your codebase are not legally owned by your entity.
This is not a theoretical risk. It is one of the most common findings in tech M&A diligence, and it regularly causes deals to be restructured or repriced.
3
IP holding structure complexity is rarely documented
Many tech companies have moved IP to an offshore holdco — for tax efficiency, investor credibility, or both. What is less common is having the transfer properly documented: arms-length intercompany agreement, appropriate transfer pricing, updated IP register, and substance in the holding jurisdiction. An acquirer’s tax team will look at this closely.
An undocumented IP holding structure is as risky as no structure at all. It creates tax exposure, complicates the acquisition structure, and can result in significant price adjustment or escrow holdbacks at closing.
💡
The cost of fixing IP problems
The average cost of fixing IP documentation problems pre-process is a fraction of the cost of fixing them post-LOI. When an acquirer finds an IP gap in diligence, the clock is running and you are negotiating from a position of weakness. Fix it before the process, not during it.
📋 Section 2

The five most common IP ownership gaps

These are the issues that appear in the majority of tech M&A IP diligence processes. If you have more than one of these, your IP is not deal-ready.
👤
Most common
Unassigned contractor and freelancer IP
The silent majority of IP diligence failures
What it is: Contractors, freelancers, and outsourced development teams who wrote code or created IP without signing an IP assignment agreement. The service agreement says “work for hire” but does not contain an explicit assignment of all IP rights.
Why it matters: In most jurisdictions, “work for hire” does not automatically transfer IP. The contractor retains ownership unless there is an explicit written assignment. This applies retroactively — there is no statute of limitations on unclaimed IP.
How to fix it: Identify all past contractors, locate the agreements, and where missing, execute retroactive IP assignment agreements. Most contractors will sign if asked professionally — it is rarely contentious.
🔓
Technical risk
Open source licence contamination
GPL and AGPL in proprietary codebases
What it is: Copyleft open source licences (GPL, AGPL, LGPL) embedded in or linked to your proprietary code. Under GPL/AGPL, if you distribute a derivative work you may be required to open-source your entire codebase.
Why it matters: A proprietary software company that discovers GPL contamination in its core product has a serious problem. The “solution” — removing and rewriting the contaminated code — is expensive, time-consuming, and delays deals.
How to fix it: Run an open source licence audit using automated tooling (Black Duck, FOSSA, or similar). Identify all GPL/AGPL usage. Where remediation is needed, plan the rewrite before the M&A process begins.
📄
Foundational
Missing employee IP assignments and trade marks
Two problems that require immediate action
Employee IP: Employment agreements that do not include a specific IP assignment clause — or that use generic language not covering the specific IP at issue. Founders who created IP before the company was formed are a particular risk: that pre-formation IP may belong to them personally, not the company.
Trade marks: Unregistered trade marks, marks registered in the founder’s name rather than the entity, or marks not registered in key operating jurisdictions. An acquirer will not pay premium price for a brand it cannot certifiably own.
Both are fixable — but they require lead time. Trade mark registration takes 3–9 months depending on jurisdiction. Do not leave this for the week before signing.
⚠️
The gap that stops deals
If your product was built with contractors who did not sign IP assignment agreements — and you cannot locate signed agreements for the key developers — the IP may not belong to your company regardless of what your contracts say. This is the single most common reason tech M&A deals restructure or fail at the IP diligence stage.
✅ Section 3

IP due diligence: what buyers check

This is the minimum documentation set an acquirer’s IP counsel will request. If you cannot produce every item on this list, you are not ready for an M&A process. Work through it before you engage an investment banker or accept an LOI.
📋
IP diligence readiness checklist
8 items — minimum for any tech M&A process
Deal-ready
Signed IP assignment agreements from all contractors and freelancers
Every person who contributed to the codebase or created IP for the company — including historical contributors — should have a signed assignment agreement on file. Retroactive assignments are acceptable if signed before the diligence process begins.
Employment agreements with explicit IP assignment clauses for all past and current employees
Standard employment agreements — especially those drafted before the company had a tech lawyer — often lack adequate IP assignment language. Review every founder and key employee agreement.
Open source licence inventory with no GPL/AGPL in proprietary core product
A documented inventory of all open source components used, their licences, and confirmation that no copyleft licences are embedded in or linked to the proprietary codebase.
Run: FOSSA / Black Duck / Snyk
Trade mark registrations in all current and target operating jurisdictions
Registered in the company’s name (not founder personal names). At minimum: EU (EUIPO), US (USPTO), and any other jurisdictions representing >10% of revenue or the acquirer’s target market.
Domain names and social accounts registered in company name
Primary domain, all relevant TLDs, and social media handles registered to the company entity — not the founder personally. This is a common oversight in early-stage companies.
Third-party licence agreements reviewed for change-of-control provisions
Key software licences, data licences, and API agreements often have change-of-control clauses that require consent on acquisition. Identify these in advance so the acquirer is not surprised — and so you can negotiate consent before closing.
IP holding structure documented with transfer pricing and intercompany agreements
If IP has been transferred to a holding entity, the transfer must be documented: IP transfer agreement, transfer pricing methodology, and evidence of substance in the holding jurisdiction. Undocumented IP transfers are a significant tax and deal risk.
No pending IP claims or infringement disputes
Disclose any cease-and-desist letters received, any pending trade mark oppositions, any patent infringement claims, or any disputes with former employees or contractors over IP ownership. Undisclosed disputes discovered in diligence are a red flag regardless of their merits.
📌
This is the minimum
An acquirer’s IP diligence will go significantly deeper than this checklist. But if you cannot tick every item here, you have a problem that will surface in diligence. Fix the checklist first — then prepare for the deeper questions.
🚦 Section 4

Red flags vs yellow flags: how acquirers price IP risk

Not all IP problems are equal. Acquirers and their counsel categorise IP issues into those that stop deals (red flags) and those that reduce price or add conditions (yellow flags). Knowing the difference helps you prioritise what to fix.
🔴 Red flags — deals stop here
Issues that require resolution before closing — or kill the deal
GPL/AGPL contamination in proprietary core
If the copyleft licence infects the acquirer’s products post-close, they face an obligation to open-source their own IP. No acquirer accepts this without full remediation.
No IP assignments from core development team
If the primary architects of the product — especially offshore — never signed assignment agreements, ownership of the core IP is legally ambiguous. This is a deal stopper without retroactive remediation.
IP held in founder’s name, not entity
Core IP registered in a founder’s personal name, not the company. Requires a formal IP assignment before close, which may have tax implications and timing risk.
Pending patent infringement or ownership claims
Active litigation or credible claims against the company’s IP rights. Acquirer will not close until resolved or adequately indemnified — usually through escrow arrangements that significantly affect net proceeds.
🟡 Yellow flags — price and conditions
Issues that reduce valuation or add closing conditions
⚠️
Peripheral contractor IP unassigned
Freelancer work on non-core features without signed assignments. Fixable retroactively — typically results in a price adjustment or escrow holdback until resolved post-close.
⚠️
Trade marks not registered in all target markets
Registered in home market but not in the acquirer’s target geographies. Acquirer may apply a value haircut for the cost of gap registrations, particularly for brand-heavy acquisitions.
⚠️
IP holdco substance unclear under BEPS
IP held in a low-tax jurisdiction but without documented R&D activity, real employees, or genuine development costs. Tax team will flag — likely results in a tax indemnity or price adjustment.
⚠️
Change-of-control clauses in key licences
Critical third-party licences (data, API, software) that require counterparty consent on acquisition. Typically manageable — but must be disclosed and consent obtained before close.
Red flags stop deals or require full remediation before closing. Yellow flags cost money — typically 5–20% of deal value in escrow holdback, price adjustment, or indemnity obligations. The cost of fixing yellow flags pre-process is almost always less than the price reduction they generate in negotiations. Fix them early.

IP clean-up timeline: five stages
Work through these in order — not in parallel
5 stages
1
IP audit and mapping
6–8 weeks
Map every IP asset: software codebase, data sets, trade marks, domain names, patents, and any licences given or received. Identify who created each asset, when, under what agreement, and whether IP ownership has been properly documented. This is the diagnostic phase — it tells you what needs fixing.
2
Assignment agreements and documentation clean-up
4–8 weeks (concurrent with Stage 1)
Execute retroactive IP assignment agreements with all contractors and freelancers who are missing them. Update employment agreements for current employees. Formally transfer any IP still in founder names to the company. This is primarily an administrative exercise — most counterparties will cooperate if asked promptly and professionally.
3
Open source licence audit and remediation
4–12 weeks depending on severity
Run automated open source scanning across the codebase. Produce a full licence inventory. If GPL/AGPL contamination is found, scope the remediation: identify whether the contaminated code can be isolated, replaced, or rewritten. Begin remediation immediately — this is the most time-consuming fix and cannot be left until the M&A process begins.
4
Trade mark registrations
3–9 months to registration
File trade mark applications in all current operating jurisdictions and any markets the acquirer is likely to enter. Transfer any marks currently in founder names to the company. File immediately — trade mark registration timelines mean this must start well before any M&A process. An application in progress at LOI is significantly better than no application.
5
IP holding structure review
4–8 weeks
If you have an IP holdco, ensure the transfer documentation is complete: intercompany agreement, transfer pricing documentation, updated IP register, and evidence of substance in the holding jurisdiction. If the structure cannot be properly documented, consider whether it is worth maintaining — an undocumented IP holdco adds more deal complexity than tax efficiency justifies.
