Trademark Assignment: How to Transfer Ownership of a Mark

Trademark Assignment: How to Transfer Ownership of a Mark

Whether you're selling a business, restructuring a corporate entity, or purchasing a brand, transferring trademark ownership requires a formal assignment. Done correctly, it's a straightforward process. Done incorrectly, it can void the trademark entirely. This guide covers everything you need to know about trademark assignments.

What Is a Trademark Assignment?

A trademark assignment is a permanent transfer of ownership of a trademark from one party (the assignor) to another (the assignee). Unlike a license — which grants permission to use a mark — an assignment transfers all rights, title, and interest in the mark.

Assignments can cover:

• Registered trademarks — Marks that have been registered with the USPTO
• Pending applications — Applications that are still being examined
• Common law marks — Unregistered marks used in commerce
• Intent-to-use applications — Under certain conditions (see below)

Assignment vs. License

Understanding the difference between assignment and license is critical:

*Citation: TMEP Chapter 500 — Assignments and Other Documents*

The Goodwill Requirement

This is the most important rule in trademark assignment law: you must transfer the goodwill associated with the mark. A trademark has no legal existence separate from the goodwill of the business it represents.

An assignment without goodwill — called an "assignment in gross" — is legally void. The mark becomes abandoned, and the assignee receives nothing of value.

What Counts as Goodwill?

Goodwill includes:

• Customer recognition and loyalty associated with the mark
• The reputation built under the mark
• The business practices, quality standards, and customer relationships
• Physical assets related to the marked goods/services (optional but strengthening)

Pro Tip: Always include this language in your assignment agreement: "together with the goodwill of the business symbolized by the Mark and associated therewith." This single clause can mean the difference between a valid and void assignment.

Types of Assignments

Full Assignment

Transfer of all rights in the mark for all goods and services. The most common type.

Partial Assignment

Transfer of rights for specific goods/services only. For example, assigning the right to use "ACME" for clothing while retaining rights for electronics. Partial assignments must be carefully drafted to avoid creating confusion in the marketplace.

Assignment of Application

A pending trademark application can be assigned. However, for intent-to-use (ITU) applications, special rules apply:

• An ITU application cannot be assigned before the Statement of Use is filed, unless the assignment is to a successor of the applicant's business (the business that intends to use the mark)
• This rule prevents trafficking in trademark applications

Assignment as Part of Business Sale

When a business is sold through an asset purchase agreement, all trademarks typically transfer as part of the deal. The trademark assignment should be executed as a separate document and recorded with the USPTO.

Essential Terms in the Assignment Agreement

A well-drafted trademark assignment agreement should include:

1. Identification of parties — Full legal names of assignor and assignee
2. Description of the mark — The exact mark being transferred
3. Registration/serial numbers — All relevant USPTO numbers
4. Goods and services — What the mark covers
5. Goodwill clause — Express transfer of goodwill (critical!)
6. Consideration — What the assignee is paying (can be nominal)
7. Effective date — When the transfer takes effect
8. Representations and warranties — Assignor represents they own the mark, it's valid, not subject to liens, etc.
9. Further assurances — Both parties agree to execute additional documents as needed

USPTO Recordation

After executing the assignment agreement, you should record it with the USPTO.

How to Record

*Citation: 37 CFR Part 3 — Assignment, Recording, and Rights of Assignee*

Why Recording Matters

While an assignment is legally effective between the parties upon execution, recording with the USPTO provides:

• Constructive notice to the public of the ownership change
• Priority over subsequent conflicting assignments
• Updated USPTO records — important for maintenance filings, licensing, and enforcement
• Clear chain of title — essential if the mark is later sold again or litigated

Pro Tip: Even though USPTO recordation is free for electronic filings, many assignees fail to record. This can create significant problems later — especially during maintenance filing windows, enforcement actions, or subsequent sales. Always record promptly.

Common Mistakes to Avoid

1. Assignment in Gross (No Goodwill)

Transferring the mark without the associated goodwill makes the assignment void and the mark abandoned. Always include the goodwill transfer clause.

2. Failing to Record with the USPTO

An unrecorded assignment creates a gap in the chain of title that can cause problems for years.

3. Incorrect Assignee Information

If the assignee's legal name or entity type is wrong, the assignment may need to be corrected — adding time and cost.

4. ITU Application Restrictions

Assigning an intent-to-use application before filing the Statement of Use (except to a business successor) is prohibited and can invalidate the application.

5. Forgetting Related Applications

If the assignor has multiple applications or registrations for the same or similar marks, all related marks should be assigned together to avoid confusion.
