What a Trademark Audit Is
A trademark audit is a structured review that compares two things: what your business actually uses as brand identifiers, and what you have legally protected. Over time those two lists drift apart. You launch new products, add service lines, expand into new states or countries, rebrand a sub-product, acquire another company — and the registrations rarely keep pace automatically. An audit closes that gap before it turns into a dispute or a deal-breaker.
When You Need One
- Before fundraising or due diligence. Investors and acquirers scrutinize IP. Gaps and ownership errors reduce valuation or stall the deal.
- Before international expansion. Entering new markets means checking whether your mark is even available — and protected — there.
- Before a rebrand. A rebrand needs a clean inventory of existing rights to abandon and new names to clear — when Facebook renamed its parent company Meta in 2021, a much smaller AR/VR company that had been trademarking "Meta" branding for years was already on the register, and the mismatch turned into a public trademark dispute. A pre-rebrand audit exists to catch exactly that kind of collision before a launch event does it for you.
- After a merger or restructuring. Marks frequently end up registered to the wrong entity after corporate changes.
- Periodically. An annual review catches lapsing registrations and unprotected new products.
The Trademark Audit Checklist
- Inventory every brand asset in use. Company name, product names, logos, slogans, taglines, domain names, social handles, and packaging trade dress.
- List every registration and application. Pull your full USPTO portfolio (and any foreign registrations), with serial/registration numbers, classes, and status.
- Match the two lists. Flag any in-use asset with no corresponding registration — these are your exposure points.
- Check the classes. Confirm each registration actually covers the goods and services you now sell. A mark registered only in Class 25 doesn't protect your new Class 35 retail business.
- Verify ownership. Confirm the registered owner is the current operating entity. Record assignments where it isn't.
- Check maintenance deadlines. Identify upcoming Section 8 and Section 9 deadlines so nothing lapses.
- Prune dead weight. Note marks no longer in use — keeping them may invite abandonment challenges, or they may be worth licensing or selling.
- Document and prioritize. Turn findings into an action list: file new applications, record assignments, renew, or abandon.
The single most damaging audit finding is usually ownership mismatch: the trademark is registered to a founder personally, an old entity, or a dissolved company rather than the business that operates the brand. This can derail an acquisition. Fix it with a recorded assignment before it surfaces in someone else's due diligence.
What to Do With the Results
An audit is only useful if it drives action. The output should be a prioritized plan: which gaps to file on first (start with your core brand and revenue-driving products), which registrations to renew immediately, which assignments to record, and which unused marks to drop or monetize. For ongoing protection, fold the audit into a broader brand protection strategy with monitoring and a renewal calendar so the gaps don't reopen.
Frequently Asked Questions
What is a trademark audit?
A systematic review that compares the brand assets your business actually uses — names, logos, slogans, products — against what you've legally registered, to find gaps, lapsing registrations, and ownership problems.
When should a business do a trademark audit?
Before fundraising or due diligence, before international expansion, before a rebrand, after a merger or restructuring, and ideally on an annual basis to catch unprotected new products and approaching deadlines.
What's the most common problem a trademark audit finds?
Ownership mismatches — where the mark is registered to a founder, an old entity, or a dissolved company instead of the current operating business — along with in-use brands that were never registered and missed maintenance deadlines.
Can I do a trademark audit myself?
You can do the inventory and portfolio review yourself, but ownership corrections, class-coverage analysis, and clearance of new marks are usually worth professional input, especially ahead of a transaction.
