IP Audit

What is an IP audit?

An IP audit is a structured, systematic review of all intellectual property assets that a company owns, uses, or licenses. The audit maps out what IP exists (patents, trademarks, copyrights, trade secrets, domain names), verifies that ownership is properly documented, identifies encumbrances and third-party rights, flags risks, and reveals gaps in protection. The result is typically an IP register — a catalog of all identified assets — along with a legal assessment of their strength, status, and strategic value. IP audits range from narrow scope (confirming startup founders properly assigned their patents before a Series A) to comprehensive enterprise-wide assessments spanning global portfolios.

Why IP audits matter

Intellectual property is often a company's most valuable asset, yet it is also among the most misunderstood and poorly documented. Companies routinely overestimate what they own (assuming informal creation equals legal ownership) and underestimate risks they carry (licensed-in IP that restricts commercialization, open-source obligations, prior art that narrows patent claims). For startups, an IP audit before a funding round surfaces ownership gaps that can delay or kill a deal — a common example is an engineer who developed key technology before signing a PIIA (Proprietary Information and Inventions Assignment agreement). For larger companies, audits drive portfolio rationalization and reveal licensing opportunities that generate revenue.

What an IP audit covers

A comprehensive IP audit examines: (1) Patents — filed, pending, and granted applications; maintenance fee status; assignment chain from inventor to company; encumbrances (licenses, pledges, liens); expiry dates. (2) Trademarks — registered marks and common-law marks; jurisdictions covered; renewal status; any disputes or opposition proceedings. (3) Copyrights — key works (software, documentation, marketing materials, product designs); authorship and work-for-hire documentation; third-party content embedded in company works. (4) Trade secrets — what qualifies, how it is protected (access controls, NDAs, documented reasonable precautions). (5) Licensed IP — any IP licensed in from third parties, including open-source software; scope of license, restrictions, and compliance status. (6) Domain names and social handles — registration status, expiry, any cybersquatting issues.

The most common finding: ownership gaps

The single most common and dangerous IP audit finding is an ownership gap — IP that was created by a person or entity who never formally assigned rights to the company. Common scenarios: a co-founder who left before signing an assignment agreement; a contractor who developed software or a product concept without a written IP assignment clause in the contract; an employee who had a pre-employment IP agreement that carved out prior inventions but the scope was not clearly documented; or a company that acquired a product line without specifically assigning the IP in the acquisition agreement. These gaps can cloud title to critical IP and create serious issues in M&A deals, licensing negotiations, and patent enforcement.

IP audit for startups: pre-funding checklist

For startups preparing for a funding round, the essential IP review focuses on: (1) Confirm every co-founder and early employee signed a PIIA (Proprietary Information and Inventions Assignment) or equivalent before doing any substantive work. (2) Confirm any contractors or consultants who built core technology signed an IP assignment clause — a confidentiality clause alone is not sufficient. (3) Review all filed patents to confirm proper assignment recordation at the USPTO. (4) Identify any key technology that is not yet patent-protected and assess whether it should be. (5) Review all software dependencies for open-source licenses that could restrict commercialization (particularly copyleft licenses like GPL). (6) Confirm trademark registrations in the company's key markets.

IP due diligence in M&A

In mergers and acquisitions, IP due diligence is a primary area of investigation for acquirers. The acquiring company's counsel will review: the patent portfolio for validity and enforceability; any IP litigation history; all IP licenses (both in and out) and whether they are assignable; any encumbrances such as security interests in IP; whether the target has freedom to operate with its core products; and whether key IP is properly owned by the entity being acquired (not by a founder personally or a subsidiary). Material IP issues discovered during due diligence can result in price adjustments, specific representations and warranties in the acquisition agreement, escrow arrangements, or deal termination.

Trade secret audit

Trade secrets require active protection measures to be legally enforceable. An audit of trade secret protection reviews: what information qualifies as a trade secret (customer lists, formulas, source code, manufacturing processes); whether reasonable measures have been taken to keep it secret (password protection, access controls, marking documents 'confidential'); whether employees and contractors with access have signed NDAs; and whether departing employees are subject to exit interviews and reminded of their obligations. Courts have denied trade secret protection where companies failed to take reasonable precautions — the audit documents these measures and identifies gaps before litigation makes them relevant.

Deliverables from an IP audit

A well-conducted IP audit produces: an IP register listing every identified asset with status and key dates; an ownership matrix confirming (or flagging gaps in) the chain of title for each asset; a risk register cataloging identified risks (ownership gaps, infringement risks, lapse risks, licensing issues); an opportunity register identifying assets with licensing or monetization potential and IP areas where protection should be obtained; and a remediation plan prioritizing actions to address identified gaps and risks. The remediation plan typically includes assignment agreements to be executed, filings to make, licenses to obtain, and policies to implement.
