Direct answer
Trademark due diligence should build a current trademark and brand schedule, verify ownership and chain of title, review status and maintenance, assess licences and coexistence arrangements, test use and brand-control evidence where relevant, and identify conflicts or restrictions that could affect a transaction.

Discuss Trademark Due Diligence
A trademark review should verify the legal and commercial brand position
- Which marks and applications are material to the business?
- Who currently owns each registration or application?
- Are maintenance, renewal and territorial records current?
- Which licences, coexistence agreements or restrictions apply?
- Are there material conflicts, disputes or gaps in brand control?
Evidence note: USPTO guidance directs users to TSDR and ownership records for current trademark status and chain-of-title information rather than relying on brand use alone.
Video context
The research section below explains how to verify ownership, territorial coverage, use and contractual restrictions across a trademark portfolio.
Research analysis
Trademark Due Diligence should be performed as an evidence-reconciliation exercise tied to a specific financing, investment, acquisition or governance decision. The review should cover registrations and applications, current ownership, assignment history, territorial coverage, renewal and maintenance and the other material items within scope, then record inconsistencies, open questions and remediation steps without assuming that a data room or spreadsheet is accurate merely because it exists.
Build the trademark and brand schedule
The schedule should include registered marks, pending applications, material unregistered marks where relevant, domains and key brand assets used in commerce.
For trademark due diligence, the reviewer should connect this issue to the transaction purpose, the evidence available on the review date, and the specific risk created if the record is incomplete or inconsistent. The analysis should distinguish verified facts from management statements, assumptions and items awaiting specialist review.
The workpaper file should preserve the source document, issue description, responsible owner and proposed treatment. Where local corporate, contract, employment, IP, privacy, regulatory or securities law controls the outcome, the page should identify that dependency rather than present a universal rule.
Verify current ownership and chain of title
Current ownership should be checked against official records and underlying assignments rather than inferred from brand use or website ownership.

Review status, renewals and territorial coverage
Registration status, renewal deadlines and geographic coverage should be matched to the markets and brands the transaction relies upon.

Assess licences, coexistence and consent arrangements
Trademark licences, coexistence agreements and consents can restrict expansion, transfer or enforcement and should be reviewed with their territorial and product scope.

Review use and brand-control evidence
Where continued use is legally relevant, the company should preserve evidence supporting use and control. Licence quality-control requirements may also matter.

Trademark remediation and closing readiness
Ownership corrections, renewal actions, consent requirements or incomplete assignments should be addressed before the transaction relies on the affected brand.

Limitations and purpose-specific context
Due diligence is transaction- and jurisdiction-specific. This framework does not replace local legal advice, patent or trademark opinions, technical review, accounting diligence, tax advice, privacy review or other specialist work where those issues are material.
