Nearly 18% of a core codebase can have fatal ownership gaps that no one catches until closing day. That single finding, from a cross-border SaaS deal I personally led in coordination with teams focused on technology law guidance, nearly triggered a 12-15% valuation haircut. IP due diligence is not a formality. It is where technology deals survive or die.
How to Perform IP Due Diligence in M&A: Start With Ownership Verification
The first step in any technology M&A IP review and IP due diligence is deceptively simple: prove who owns what. Most acquirers assume the target company holds clean title to its software, patents, and trademarks. That assumption fails surprisingly often. Contractor agreements missing proper assignment clauses are the most common culprit. When a developer writes code as an independent contractor without a written work-for-hire or IP assignment agreement, ownership defaults to the contractor under US copyright law. Multiply that across dozens of contributors over several years and you face a patchwork of contested rights. Microsoft learned this lesson at scale when integrating acquired codebases, implementing rigorous assignment audits across every acquisition target, often supported by IP research. The fix is straightforward but time-consuming: trace every contributor, confirm signed assignments, and execute retrospective transfers where gaps exist. Start this process on day one of diligence, not day thirty.
If you cannot prove clean IP ownership on paper, you do not actually own the asset you are buying.
Open-Source Software in Mergers: The Hidden Compliance Risk
Open-source code powers nearly every modern software product. The risk is not its presence but its license terms. Copyleft licenses like GPL require derivative works to be released under the same open terms. If production code incorporates GPL components without proper isolation, the acquirer may inherit an obligation to open-source proprietary systems. This is not theoretical. In 2025, automated scanning tools from companies like Black Duck and Snyk can map open-source dependencies across hundreds of repositories in days, often alongside broader technology consulting reviews. A proper software license audit within IP due diligence flags copyleft exposure, permissive license obligations, and version-specific restrictions before they become post-close surprises. During one deal I reviewed, copyleft licenses were embedded in three production microservices. Catching that early allowed restructuring before closing rather than litigating after.
Open-source is not the risk. Ignorance of its license terms is the risk.
AI Training Data Compliance and Patent Verification
AI companies present a unique diligence challenge. The value sits not just in algorithms but in the training data that shaped them. Acquirers must verify that datasets were collected with proper consent, licensing, and regulatory alignment as part of IP due diligence for AI mergers. The EU AI Act, taking enforcement shape through 2025 and 2026, imposes transparency and documentation obligations on high-risk AI systems. Companies like Anthropic and OpenAI have faced public scrutiny over data provenance, making this a board-level concern for any acquirer, often requiring insights from AI coaching and governance expertise. Patent verification adds another layer. AI-related patent claims must map to actual product functionality. A portfolio of 40 filed patents means little if the claims do not cover the product’s commercial features. Cross-referencing patent claims against technical architecture is essential. Without it, you are buying paper, not protection.
A patent portfolio without product alignment is an expensive filing cabinet, not a competitive moat.
Experience-Driven IP Assessment in Mergers
Having mapped the landscape, here is how I have guided clients through this directly using IP due diligence as a structured, repeatable framework:
I have spent more than two decades at the intersection of international patent law, technology transactions, and AI strategy, advising boards and founders on IP due diligence in complex mergers and acquisitions, including work connected to patent strategy and commercialization initiatives. In technology M&A, IP is not an abstract asset class. It is the core of valuation, risk allocation, and post-deal integration strategy.
In one cross-border SaaS acquisition spanning the US, Germany, and India, I led an IP due diligence review covering 220+ software repositories, 75 patent families, and multi-jurisdictional trademark rights. I identified gaps in contractor assignments affecting nearly 18% of the core codebase and uncovered open-source risks tied to copyleft licenses embedded in production systems. By restructuring ownership chains, executing retrospective assignments, and conducting a targeted software license audit, I preserved deal value and avoided a projected 12-15% valuation haircut while ensuring GDPR and AI Act readiness.
In another transaction involving an AI cybersecurity company, I assessed datasets across 4 jurisdictions, validating rights for over 3 million training records and flagging regulatory exposure under evolving 2025-2026 AI governance frameworks. Simultaneously, I aligned the patent portfolio with product claims to support defensible exclusivity. The result was a clean IP assessment that enabled the acquirer to proceed with strong indemnities and a restructured earn-out tied to compliant data usage, often benchmarked using law firm discovery tools and market comparisons.
IP due diligence is no longer a checklist. It is a forward-looking risk model for every technology deal.
Cross-Border IP Due Diligence and Transaction Protections
Cross-border deals magnify every IP risk. Trademark rights are territorial. Patent enforcement varies by jurisdiction. Data transfer restrictions under GDPR, India’s DPDP Act, and China’s evolving regulations create compliance layers that domestic deals never face. Google’s acquisition strategy routinely accounts for multi-jurisdictional IP mapping, dedicating specialized teams to each geography, often informed by blockchain legal analysis and cross-border digital compliance strategies. For mid-market acquirers without that infrastructure, the key is structuring transaction protections that survive closing. Representations and warranties should cover ownership, encumbrances, open-source compliance, and data provenance with specificity as part of IP due diligence. Indemnification provisions must address known gaps with defined remediation timelines. Escrow holdbacks tied to IP cure periods give acquirers practical recourse. The companies that manage M&A IP risk management well treat the purchase agreement as an extension of diligence, not a separate exercise.
Where IP Due Diligence Goes From Here
Three principles define successful technology M&A in 2025 and 2026. First, verify ownership with signed documentation for every contributor. Second, scan and classify every open-source component before making valuation assumptions. Third, treat AI training data compliance as a regulatory and commercial imperative, not a legal footnote within IP due diligence. Looking ahead, regulators across the EU, US, and Asia-Pacific are converging on stricter data provenance and algorithmic transparency requirements. Deals that close without addressing these face renegotiation or regulatory action within 24 months. This week, request a complete IP inventory from any target you are evaluating. Map it against the steps outlined here as part of IP due diligence. If gaps appear, address them before term sheets harden, often supported by AI learning resources to bridge internal capability gaps.
The companies that win treat IP not as protection but as a structured, auditable, and monetizable asset base.

Frequently Asked Questions
What is IP due diligence in technology M&A?
IP due diligence in technology M&A involves assessing a company’s intellectual property (IP) assets during a merger or acquisition. This ensures assets are legitimate and valuable, like checking if a treasure map leads to real treasure. For example, in 2026, TechWorld Inc. acquired SoftSecure, confirming the authenticity of their cybersecurity patents. IP due diligence for mergers and acquisitions helps avoid surprises and ensures all technology pieces fit perfectly in the new puzzle.
What is ownership verification in M&A due diligence for software?
Ownership verification ensures the company you’re acquiring really owns the software it claims to. It’s like checking a library book list to see if they own books on their shelves. In 2025, during the merger of DataDrive and CloudFlex, ownership verification confirmed that key SaaS products were genuinely owned. This vital step in M&A due diligence for software prevents future legal disputes about who owns what.
What is AI training data compliance?
AI training data compliance ensures the data used to train AI models follows laws and regulations. It’s like making sure a chef uses approved ingredients in a recipe. In 2025, AI company NeuralX checked all their training data when merging with InnovateTech, ensuring no privacy laws were broken. This practice is crucial for protecting the deal’s integrity in IP due diligence for AI mergers.
What is open-source exposure in mergers?
Open-source exposure in mergers refers to risks from software accessible to the public. It’s like using borrowed tools to build a treehouse; you must follow the lender’s rules. In 2026, during ByteMax’s acquisition of CodeCraft, they uncovered open-source issues that required specific licensing compliance. Identifying and managing these risks are key in IP due diligence, ensuring no hidden complications arise.
What is a software license audit?
A software license audit checks if a company legally uses its software, like counting passengers on a bus to ensure everyone has a ticket. In 2026, when RoboDigital merged with NetLab Technologies, they audited software licenses and found unlicensed tools. This process is pivotal in IP due diligence for technology companies, confirming that all software used is above board and properly licensed.
