Most founders assume that having registered trademarks and patents means their intellectual property is in order. It’s a reasonable assumption. It’s also incomplete.
When sophisticated buyers and investors conduct due diligence, registration is only the starting point. What they’re really assessing is whether the company’s IP is owned cleanly, protected actively, and free of exposure that could complicate — or derail — a transaction.
Here’s what that review actually looks like.
Ownership Chain
Startups often move fast in the early days — domains get registered, brands get filed, and code gets written before the company is properly formed or while ownership is still informal. A founder registers the trademark in their own name. A contractor builds the core product without a written agreement. A co-founder leaves before anyone thinks to document what they contributed.
These situations are common and usually fixable. But buyers will find them, and an ownership chain with gaps — even old ones — creates real friction at closing.
In some cases, particularly where long-term asset protection is a priority, it may also make sense to hold IP in a separate entity and license it back to the operating company — a structuring decision worth considering well before any transaction is on the horizon.
Registered and Unregistered Rights
Registration captures only part of a company’s IP. Trade secrets, unregistered marks, and proprietary processes can be just as valuable — sometimes more so. Buyers want to know what exists and whether it’s actually protected: enforceable NDAs, confidentiality obligations, and controlled access.
Enforcement History
Has the company enforced its IP against infringers? A registered mark that has never been defended is a weaker mark. Buyers assess whether the company has been a passive or active owner of its rights.
This matters more than founders often realize. We routinely help e-commerce brands pursue infringers and obtain injunctions that shut down infringing Amazon, Shopify, and eBay stores. The brands that have done this work have a stronger IP story to tell in due diligence. The ones that haven’t — even with valid registrations — are in a weaker position at the table.
Violations Received
Cease and desist letters, infringement claims, and ongoing IP disputes have a way of getting filed away as something to deal with later — or not at all. In my experience, these are often received, noted, and set aside. Years pass. Then they surface in due diligence, and what was once a manageable issue has become a material problem that the buyer is now pricing into the deal.
Software IP
For software companies, the IP stack gets examined closely. Open source components, licensed dependencies, and third-party libraries all carry their own terms. Buyers want to know whether those terms were followed — and whether any of them compromise the company’s ownership claims over its own product.
The pattern across all of these issues is the same: they’re rarely created at the time of a transaction. They accumulate quietly over years of building. Addressing them before a process begins is almost always easier — and less costly — than negotiating around them at the table.
