The Business Name on Your Formation Documents vs. Trademark Rights: What’s the Difference?

When you register your business with your state, you pick a name and put it on the formation documents you file with the state to ask the state to let you use that name as the official legal business name.

Maybe you’ll also file an assumed name application if you’d like to use a different name with the public than the legal business name.

On paper, then, you have a legal business name and perhaps an assumed name for the business. That DOESN’T mean you have the right to use either of those names publicly in connection with your business. That may seem all kinds of wrong, but it’s accurate.

Trademark rights are indeed a completely separate issue—at the federal level (via the U.S. Patent and Trademark Office), the state level, or even at common law (which is use without registration and based on actual use in commerce). Trademark rights are about who owns the right to use that business name with the public.

If you don’t have the trademark rights to a name, using it with the public is risking an accusation of trademark infringement. You need to assess your trademark rights separately before you use a name with the public.

Thinking about filing a trademark before you launch? Intent-to-Use applications and specimen requirements are more complex than they appear. Patent attorney Julie King explains what goes wrong and why trademark attorney guidance matters. You’ve got a great brand name. Maybe you’ve designed a logo.

Trump trademarks and the Domestic Emoluments Clause

Current Events: Trump Trademarks and the Domestic Emoluments Clause

How Trump Business Ownership of Airport Trademarks Would Violate the Domestic Emoluments Clause: How does the Domestic Emoluments Clause apply to these trademark applications? Who names airports? That’s right, Congress does, for airports under federal jurisdiction, and the states do for state-owned airports.
Trump has asked for the Palm Beach International Airport and Dulles International Airport to be named after him. Given that these applications also cover airport construction, it’s not a leap to think there may be future airports Trump wants to be named “DONALD J. TRUMP INTERNATIONAL AIRPORT” and/or “PRESIDENT DONALD J. TRUMP INTERNATIONAL AIRPORT,” especially if the proposed renaming of the Palm Beach and Dulles airports doesn’t happen. Note that the trademarks for the Ronald Reagan Washington National Airport are owned by the public entity that runs the airport, Metropolitan Washington Airports Authority (DISTRICT OF COLUMBIA Federal Agency Assignee of United States (D.C. Body Politic and Corporate) ), NOT a private company.
