For a lot of small businesses, the brand, the recipe, the software, or the customer relationships are worth more than the physical equipment on the premises. Yet intellectual property is one of the areas buyers investigate the least carefully — it doesn't show up on a balance sheet the way inventory or equipment does, and confirming ownership takes a different kind of digging than reviewing financial statements.
Intellectual property due diligence means identifying every IP asset the business actually relies on, then confirming the seller genuinely owns (or has the right to use) each one, and that it will actually transfer as part of your deal. Skipping this step is one of the most common ways a buyer discovers, after closing, that a core part of what they thought they bought isn't actually theirs.
Categories of IP to Identify
Work through each of these systematically rather than assuming none apply:
| IP Type | Examples in a Small Business | Why It Matters |
|---|---|---|
| Trademarks / brand names | Business name, logo, taglines, product names | Confirms the buyer can keep using the brand customers already recognize |
| Copyright | Website content, marketing materials, software code, photography, written manuals | Copyright often belongs to whoever created it, not automatically to the business that uses it |
| Trade secrets / know-how | Recipes, processes, supplier lists, pricing formulas | Usually unregistered — protection depends on how carefully it was actually kept confidential |
| Domain names and social accounts | The business's website domain, email domain, social media handles | Easy to overlook, but often essential to keep operating under the same identity |
| Software and technology licences | Point-of-sale systems, custom software, SaaS subscriptions | Some licences are personal to the seller and don't automatically transfer to a new owner |
| Patents (less common in small business) | A patented product, process, or design | Confirm registration status and remaining protection period, if relevant |
Confirming Actual Ownership: Chain of Title
Identifying an IP asset is only step one. The harder question is whether the seller actually owns it cleanly:
- Was it created by an employee, or by an outside contractor or agency? Work created by an employee within their job duties generally belongs to the employer, but work created by an outside contractor may still belong to the contractor unless there's a written assignment transferring it to the business.
- Is there a written assignment on file? For anything created by a freelancer, developer, designer, or agency, look for a signed agreement that actually assigns ownership to the seller's business — a verbal understanding or an invoice alone usually isn't enough.
- Is the asset registered, and in whose name? For trademarks in particular, check whether the registered owner listed matches the seller entity exactly. A mismatch (a name registered personally rather than to the corporation, for example) is a common and fixable — but easily missed — problem.
Building IP Protection Into the Deal
Once you know what exists and how clean the ownership picture is, standard purchase agreement tools apply:
- Representations and warranties that the seller owns (or validly licenses) all IP used in the business, and that no third party has challenged that ownership
- A disclosure schedule listing every trademark, domain, key contract, and licence, so nothing is left to informal assumption
- Specific assignment documents for trademarks, domains, and any other registrable or transferable assets, executed and, where applicable, recorded with the relevant registry at or after closing
- Indemnities allocating the risk if an IP ownership problem surfaces after closing
Frequently asked questions
Does buying the shares of a company automatically transfer its intellectual property?
Generally, yes for IP already validly owned by the corporation — the corporation's assets, including IP, come with a share purchase. The bigger risk in a share deal is IP the corporation never actually owned cleanly in the first place, not a transfer mechanics problem.
What if the seller can't find written assignments from past contractors?
This is common, especially for older or informally run businesses. It doesn't necessarily kill the deal, but it's a real risk to price in, disclose, and potentially address through a holdback, indemnity, or a requirement that the seller obtain confirmatory assignments before closing.
Do I need to register anything myself after I buy the business?
Possibly — trademark and domain ownership changes are often formally recorded with the relevant registrar, and your lawyer can advise on what needs updating so the public record matches who actually owns the asset going forward.
Is unregistered know-how still worth protecting in due diligence?
Yes. Trade secrets and know-how typically aren't registered anywhere, so due diligence has to look at how the business actually protected that information — confidentiality agreements, access restrictions — rather than a public registry.
