Trademark Licensing Due Diligence for Owners and Licensees

A trademark license can open a new market or let a business sell under an established brand. Before either party commits, it needs to understand what rights are available, what restrictions apply, and whether the relationship can work in practice.

Trademark licensing due diligence is the review of the rights, documents, business assumptions, and risks behind the proposed deal. For the owner, it helps assess whether a partner can protect the brand while meeting its obligations. For the licensee, it helps assess whether the promised rights support the planned investment.

1 Establish whether the deal is a license or an assignment

A license permits specified use of a trademark while ownership generally stays with the licensor. An assignment transfers ownership. Read the rights being granted rather than relying on the document's title. WIPO explains the distinction.

This matters when reviewing earlier transfers. Under U.S. law, an assignment of a registered mark or trademark application must include the associated business goodwill. Transfers of intent-to-use applications before filing an amendment to allege use or statement of use are restricted, with a limited exception for a successor to an ongoing business. Have counsel examine relevant transfers in the ownership history. 15 U.S.C. § 1060.

2 Verify ownership and authority to grant the license

Identify the exact legal entity granting rights and the person authorized to sign. A founder, parent company, distributor, or similarly named affiliate may not own the trademark.

Request:

• The trademark application and registration details.
• Executed assignments and relevant merger or name-change documents.
• Any upstream license if the proposed licensor is sublicensing.
• Documents explaining co-ownership, security interests, or required third-party consents.

Compare the documents with USPTO ownership and assignment records. Investigate missing transfers, inconsistent names, or rights granted by a different entity.

Public records are important evidence, but recording an assignment does not establish that the transaction is valid or that it transferred the claimed rights. The USPTO expressly says recordation is a ministerial act, not a determination of validity or title. USPTO assignment guidance.

3 Match the rights to the planned business

Create a schedule listing each word mark, logo, application, and registration, together with the proposed products, services, countries, and sales channels.

For U.S. records, use Trademark Status and Document Retrieval to review the current status, file documents, and upcoming maintenance requirements. Check outstanding office actions and changes to the listed goods or services, rather than relying on an old certificate. USPTO status-checking guidance.

Then compare the portfolio with the launch plan. Does a license for apparel also contemplate downloadable products? Are marketplaces, manufacturing locations, and cross-border shipping addressed? Identify coverage gaps for legal review before committing launch funds.

A U.S. registration does not provide worldwide protection. Check the position in each relevant country, including any unregistered rights and conflicting third-party rights. USPTO guidance on overseas protection.

4 Check earlier promises and define exclusivity

Request existing licenses, amendments, sublicenses, coexistence agreements, settlements, and other relevant restrictions. Compare them with the proposed grant to identify overlapping territories, products, customers, or channels.

Ask specifically:

• Can the owner continue selling under the mark?
• Can it license competitors or retain existing partners?
• Does exclusivity cover all uses or only a defined product category?
• May the licensee sublicense, transfer the agreement, or use affiliates?
• Are approvals required before signing or changing control?

Terms such as “exclusive,” “sole,” and “non-exclusive” should be defined in the agreement. Spell out the rights each party keeps instead of assuming a label settles the issue. WIPO identifies exclusivity, field of use, territory, and sublicensing permissions as core licensing decisions. WIPO licensing guidance.

5 Examine quality control in practice

U.S. trademark law links qualifying licensed use to the owner's control over the nature and quality of the goods or services. A “related company” in this context need not be a corporate subsidiary. 15 U.S.C. § 1055, 15 U.S.C. § 1127.

Uncontrolled or “naked” licensing can put trademark rights at risk of abandonment. The assessment is fact-specific; a particular inspection schedule is not a universal legal safe harbor. USPTO Trademark Trial and Appeal Board decision, pages 48–49.

For due diligence, review both the proposed controls and evidence of how existing licenses operate:

• Product specifications or service standards.
• Sample, packaging, and advertising approval records.
• Inspection reports, complaints, and corrective actions.
• Responsibility for oversight and the resources to perform it.

Choose workable approval deadlines and escalation steps. A clause that nobody implements is a warning sign. The USPTO emphasizes actual control; the existence of a written licensing agreement alone does not establish ownership rights. TMEP § 1201.03.

6 Investigate disputes and competing rights

Request details of threatened and pending claims, demand letters, settlements, oppositions, cancellations, and infringement litigation. Check relevant public proceedings as well as information supplied by the other party.

Search for conflicting marks in the intended market. A review limited to identical federal registrations can miss similar marks and earlier unregistered rights. The USPTO recommends checking multiple sources, including common-law use. USPTO comprehensive-search guidance.

Do not treat a clean Trademark Trial and Appeal Board search as a complete litigation search. The Board decides registration disputes, not infringement claims or damages. About the TTAB.

Agree who will monitor infringements, decide whether to act, control settlements, and pay enforcement costs. Counsel should also assess who has legal standing to bring the relevant claims.

7 Test the commercial terms and partner's capacity

Owners should assess the prospective licensee's operating experience, distribution arrangements, finances, and ability to maintain standards. Licensees should test the sales assumptions behind the proposed fees and minimum commitments. WIPO's partner due-diligence guidance.

Work through the payment mechanics using sample transactions. Check royalty definitions, permitted deductions, returns, currency, reporting dates, audit rights, and minimum payments. Consider what happens if sales are slower than forecast or exclusivity prevents another opportunity.

Review warranties, indemnities, insurance, liability limits, and the allocation of legal costs with counsel. Their wording and enforceability matter more than the presence of a familiar heading. WIPO's general licensing checklist offers useful questions on financial terms and risk allocation, although it is oriented toward technology licensing. WIPO GREEN Licensing Checklist.

8 Plan the end of the relationship

Review duration, renewal deadlines, performance requirements, breach notices, cure periods, and termination rights. Decide how the parties will handle remaining inventory, outstanding royalties, customer communications, online branding, and confidential materials when the license ends.

Any sell-off period should have clear limits and continued quality controls. Identify obligations that must survive expiry, including final accounting and appropriate confidentiality commitments. Record responsibility for removing or transferring digital assets where agreed. Canadian Trade Commissioner Service contract checklist.

Before signing, keep a written issues list: the concern, supporting evidence, responsible person, and required resolution. Treat unresolved ownership gaps or conflicting grants as decisions to resolve, not details to file away.

Cross-border licenses need local review

Licensing rules differ by jurisdiction. In Canada, section 50 addresses licensed use where the owner has direct or indirect control of the character or quality of the goods or services. Public notice identifying licensed use and the owner can create a rebuttable presumption of licensing and control. Canadian Trademarks Act, section 50.

CIPO also recommends specifying the type and quality of licensed products or services. Confirm local requirements for recordal, formalities, enforcement, and termination rather than importing U.S. assumptions. CIPO IP strategy guide.

Frequently asked questions

Is a registration certificate enough for due diligence

No. Review current status, ownership documents, actual use, existing agreements, and disputes. A certificate is one part of the evidence.

Can an unregistered trademark be licensed

Potentially. U.S. common-law rights can arise through use, but their scope and geography require investigation. Registration status should be disclosed clearly. USPTO explanation of common-law rights.

Does due diligence guarantee a safe deal

No. It helps identify and allocate risks. Findings should inform the scope, price, protections, and decision whether to proceed.
