Most businesses assume their brand, product, and technology are theirs. Legally, that’s not always true.

In today’s economy, intellectual property — trademarks, software, designs, domain names, patents — often represents the majority of a company’s value. Yet many businesses discover too late that they don’t actually own what they’ve spent years building. That’s exactly why IP due diligence has become one of the most critical steps in investment, M&A, scaling, and international expansion.

What Is IP Due Diligence?

IP due diligence is a comprehensive legal review of a company’s intellectual property assets.

Its goal is to answer four key questions:

  • Does the company actually hold rights to its IP — or are those rights sitting with a founder, former director, or contractor?
  • Is the company inadvertently infringing on third-party rights?
  • Are proper IP assignment agreements in place with employees and freelancers?
  • Are all IP assets properly registered, active, and protected in the jurisdictions that matter?

For investors and acquirers, IP due diligence answers a more fundamental question: what exactly am I buying — and what risks come with it?

What IP Due Diligence Actually Uncovers

The problems that surface during IP due diligence are rarely new. They’ve typically been there for years — quietly waiting:

  • Trademarks, patents, or designs that were never registered
  • IP rights that were never formally transferred from contractors or employees
  • Third-party assets used without proper licensing
  • Key IP held in a founder’s name rather than the company’s
  • Inadequate protection in international markets

For a while, none of these causes obvious problems. But when investment talks begin, a sale is on the table, partners fall out, or the company enters a new market — these gaps become critical. The consequences can range from losing control of your brand and marketplace bans to litigation and collapsed deals.

Real Cases Where IP Due Diligence Made or Broke the Deal

Google & Motorola Mobility — $12.5B, 2012 The headline number was striking, but the real prize was Motorola’s IP portfolio: over 17,000 patents and 7,500 pending applications. Google conducted thorough IP due diligence to assess the strategic value of these patents and their role in protecting the Android ecosystem. The IP was the deal.

Volkswagen & Rolls-Royce — a costly oversight, 1998 When Volkswagen acquired Rolls-Royce from Vickers, it got the factories, the equipment, and the production assets. What it didn’t get — and only discovered after closing — was the right to use the Rolls-Royce name. The trademark belonged not to Rolls-Royce Ltd., but to Rolls-Royce plc, an entirely separate aerospace company. VW had bought the shell without the brand.

Apple & the iPad trademark in China — $60M settlement Apple’s failure to properly verify trademark rights before entering the Chinese market led to a legal dispute with Proview. The resolution cost Apple $60 million — and temporarily halted iPad sales in China altogether.

These aren’t cautionary tales about small companies making rookie mistakes. They’re reminders that even the world’s most sophisticated businesses can suffer serious financial and reputational damage when IP isn’t properly verified.

Three Stages of Effective IP Due Diligence

1. Define Business Priorities Start by understanding what role IP plays in the deal. Which assets are business-critical? What are both parties trying to achieve? One buyer may care only about a specific patent; another needs the full IP portfolio.

2. Legal Review of IP Assets This is the core of the process — a thorough analysis of all IP assets and related agreements: patents, trademarks, copyrights, software, assignment agreements, licenses, domain names. The goal is to map what exists, who owns it, and whether that ownership is clean.

3. Risk and Commercial Value Assessment With the legal picture clear, the findings are assessed through a business lens: What are the risks? What is each asset actually worth? Can it be commercialized? Does it support the company’s growth plans?

The Bottom Line

IP problems don’t appear out of nowhere. They accumulate quietly — sometimes for years — until the moment when everything is on the line: an investor meeting, a company sale, a new market entry.

So ask yourself now: are you certain your brand, code, and technology legally belong to your company? If the answer isn’t an immediate yes, it’s time for an IP due diligence review.
