Trademarks are assets — and like other assets, they can be bought, sold, licensed, inherited, or transferred between companies. Whether you're acquiring a startup, selling your business, spinning off a brand, or restructuring your corporate entities, understanding how trademark assignment works is essential to maintaining enforceable rights.
A trademark assignment is the transfer of ownership of a trademark from one party (the assignor) to another (the assignee). It can cover a single mark or an entire portfolio. It can be part of a business acquisition or a standalone transaction. Done correctly, it preserves the legal rights the mark has accumulated. Done incorrectly, it can void those rights entirely.
The Goodwill Requirement: The Most Important Rule
Here is the rule that trips up the most transactions: under U.S. trademark law, a trademark must be assigned together with the goodwill of the business with which it is associated. This is sometimes called the "no assignment in gross" rule.
What does this mean in practice? A trademark represents a connection in consumers' minds between a mark and a source of goods or services. If you sell just the mark — the name, the logo — without the business, product, or the goodwill that the mark represents, the consumer connection is severed. The law treats this as an "assignment in gross," and such an assignment is void.
If you sell only a trademark name without any associated business assets, recipes, customer relationships, or goodwill, a court may find the assignment void. The trademark could be cancelled, and the assignee gets nothing.
In most commercial transactions, the goodwill transfers automatically alongside the business assets. But in naked mark sales — where someone is just buying a brand name without an operating business — the assignment language must carefully address goodwill to avoid invalidity.
What Must Be in the Assignment Agreement
A trademark assignment agreement should include:
- Identification of the parties: Legal names and addresses of the assignor and assignee
- Identification of the mark: The trademark name or description, USPTO serial number, registration number (if registered), and the goods/services covered
- Consideration: What is being paid or exchanged (can be $1 for internal transfers)
- Goodwill clause: Explicit language that the assignment includes the goodwill of the business associated with the mark
- Representations and warranties: The assignor warrants they own the mark, it doesn't infringe third-party rights, there are no pending disputes
- Signatures: Must be signed by the assignor; the assignee's signature is best practice
- Notarization: Not required by the USPTO but recommended for international assignments
Recording the Assignment With the USPTO
Once the assignment agreement is executed, you should record it with the USPTO through the Electronic Trademark Assignment System (ETAS). Recording is not legally required for the assignment to be valid between the parties — but it is critically important for several reasons:
- Priority against third parties: An unrecorded assignment is not enforceable against a subsequent purchaser who acquires the mark without notice and records their assignment first. This is a real risk in portfolio acquisitions.
- Public record: Recording updates the USPTO database so the new owner appears as the registrant. This affects all searches, opposition proceedings, and renewal filings.
- Maintenance filings: Renewal and maintenance documents must be filed by the current owner of record. If the assignment isn't recorded, the new owner may not be able to file maintenance documents without first recording the assignment.
The USPTO recording fee is currently $40 per mark via ETAS (online filing). For a portfolio of many marks, this can add up — but it remains far cheaper than the consequences of an unrecorded transfer in a dispute.
Assignment of Pending Applications
A trademark application that has not yet registered can also be assigned. The same goodwill requirement applies. The assignee steps into the shoes of the assignor and must continue to meet the use requirements for registration.
Note: an intent-to-use application (filed on the basis that the applicant intends to use the mark) can only be assigned to a successor to the applicant's business, or to the portion of the business to which the intent-to-use relates. Assignments of intent-to-use applications before the mark is in use are strictly limited to prevent trafficking in marks.
Trademark Licensing vs Assignment
Assignment transfers ownership permanently. Licensing is different — it allows another party to use the mark while the owner retains ownership.
A trademark license must include quality control provisions. The trademark owner (licensor) must maintain control over the nature and quality of the goods or services offered under the mark. A bare license — where the owner has no control over the licensee's use — can result in "naked licensing," which can invalidate the trademark entirely.
Common licensing structures in trademark law: franchising (where brand standards enforce the quality control requirement), co-branding arrangements, and internal licenses between affiliated corporate entities.
What Happens to the Mark in the USPTO Database
After recording, the USPTO Trademark Status and Document Retrieval (TSDR) system will show the new owner. The assignment document itself becomes part of the public record. On tmarkmetric, owner portfolio pages reflect the registered owner — after recording an assignment, the mark will move from the assignor's portfolio to the assignee's.
The original registration date, serial number, and registration number do not change. The mark's history is preserved. This matters for priority disputes — a mark that was registered in 2010 and assigned in 2024 still has the 2010 priority date.
