What Prospective Investors, Licensees, and Acquirers Look for in Intellectual Property Due Diligence

What Prospective Investors, Licensees, and Acquirers Look for in Intellectual Property Due Diligence

A target company’s patents, trademarks, copyrights, and trade secrets can look impressive on paper, but intellectual property due diligence is where investors learn whether those IP assets actually support valuation, or conversely merely hide costly risk.

For prospective investors, licensees, and acquirers, due diligence goes beyond a surface inventory to test the ownership, enforceability, scope, licensing arrangements, and potential liabilities that can affect a business transaction. When a deal involves mergers, acquisitions, or other high-value negotiations, even a single weakness can alter the terms of the agreement. 

Intellectual property due diligence focuses on the practical issues that shape decision-making, such as scope and robustness of protection, chain of title, portfolio management, maintenance fees, infringement analysis, and freedom-to-operate concerns.

What Will Be Examined During IP Due Diligence 

During intellectual property due diligence, the details of the target’s complete IP position will be examined, including assets, potential infringements by third parties, and potential liabilities. IP attorneys will obtain key documentation from the target including tables of assets, assignments, encumbrances, employee and independent contractor agreements, license agreements, and documents regarding any past or pending litigations or settlements. Key individuals may be interviewed. The due diligence should occur only under a Non-Disclosure Agreement, and possibly a Common Interest Agreement. All measures should be taken to preserve attorney-client privilege, and target confidentiality.

For intellectual property investors, due diligence helps separate assets that are central to the company’s growth from those with little enforceable protection. 

Each category of IP has its own peculiar factors that will be analyzed.

For patents:

·       A tabulated collection of US granted patents and pending patent applications, ranked by strategic significance, identified by number, filing date, expiry, and claimed commercial subject matter.  An accompanying table of ex-US patents and patent applications keyed to families on the US table will also be obtained.  The portfolio will be evaluated for its capacity to deter potential competition, and as fodder in any future cross-licensing agreement.

·       Current ownership and chain of title from USPTO records

·       Patent prosecution dockets

·       Most relevant prior art

·       Maintenance schedules

·       For key patents, a comparison of granted and pending claims to commercial products or services, invention disclosures, prosecution histories, liabilities in enforcement (e.g., for software patents, subject matter eligibility), the pendency of continuations or divisionals to allow for continued prosecution of claims desirable to the investor/acquiror.

·       Freedom-to-operate (FTO) analysis of target’s current and prospective operations (to determine potential risk of infringing third-party patents)

·       Pipeline inventions (not yet filed)

·       Infringement watches

For trademarks:

·       A tabulated collection of granted and pending US trademarks, showing filing dates, expiries, and Registers (Primary/Supplemental), annotated for commercial significance.  A corresponding table of ex-US trademarks keyed to the US table will also be obtained.

·       Documentation regarding any past or pending licenses, litigations, settlements

·       A likelihood of confusion analysis of key trademarks

·       An investigation into potential liability for infringement of third-party trademarks

·       Infringement watches

For copyrights:

·       A tabulated collection of granted and pending US copyright registrations, showing filing date, expiry, author(s), title of the work, annotated for commercial significance.  A corresponding table of ex-US copyright registrations, keyed to the US table will also be obtained

·       Ownership and chain-of-title from the Copyright Office records

·       Infringement watches

For trade secrets:

·       A tabulated collection of the trade secrets by title and subject matter (generally)

·       The measures being deployed to maintain secrecy, including:

1. Contractual Controls

·        Nondisclosure agreements (NDAs) with employees, contractors, vendors, and partners

·        Confidentiality clauses in employment contracts and vendor agreements

·        Non‑compete and non‑solicitation clauses (where enforceable)

·        Trade secret acknowledgment forms signed during onboarding and exit interviews

·        Clear contractual labeling of confidential materials in collaboration or licensing deals

2. Access Restrictions

·        Role‑based access controls (RBAC) so only employees with a need‑to‑know can view the information

·        Password‑protected systems with multi‑factor authentication

·        Segregated servers or secure repositories for sensitive data

·        Physical access controls: locked rooms, badge‑restricted areas, visitor logs

·        Monitoring and logging of access to sensitive files

·        Prohibiting personal devices in sensitive areas

3. Technical and IT Security Measures

·        Encryption of data at rest and in transit

·        Firewalls, VPNs, and secure network architecture

·        Data‑loss prevention (DLP) systems

·        Automatic logoff and session‑timeout protocols

·        Restrictions on USB drives, external storage, or cloud uploads

·        Secure backup systems with controlled access

4. Document Handling Practices

·        Marking documents “CONFIDENTIAL” or “TRADE SECRET”

·        Using internal classification systems (e.g., “Level 3 Confidential”)

·        Shredding or secure disposal procedures

·        Controlled distribution lists for sensitive documents

·        Prohibiting printing or requiring approval to print sensitive materials

5. Employee Training and Policies

·        Regular training on confidentiality and trade secret handling

·        Written policies in employee handbooks

·        Annual certifications of compliance

·        Exit interviews reminding departing employees of obligations

·        Clear reporting channels for suspected leaks

6. Operational Practices

·        Limiting discussions of sensitive information to private areas

·        Restricting photography or recording in facilities

·        Using code names for projects

·        Segmenting manufacturing processes so no single employee knows the full formula

·        Keeping sensitive R&D areas off‑limits to visitors

7. Vendor and Partner Controls

·        Vendor NDAs and confidentiality agreements

·        Auditing vendor compliance

·        Secure data‑sharing platforms

·        Limiting what information is shared externally

·        Requiring subcontractors to adopt equivalent security measures

The outcome of a rigorous IP due diligence can be determinative in setting valuations and commercial terms of any deal, or it can ultimately kill the deal.
