Registering an LLC Does Not Protect Your Business Name in D.C.

The owner did everything in the order she was told. She registered the LLC with the District, filed the trade name, bought the domain, and claimed the social media handles. Her Basic Business License carries the name, and her liquor license application is pending. The sign went up in March, the menus were printed in April, and the restaurant now has eleven months of reviews under that name.

Then a letter arrives from a law firm in Chicago. Its client holds a federal trademark registration for a similar name for restaurant services, and it wants her to stop using hers.

Her first reaction is the one almost every owner has: the District approved this name. The District did approve it, for the District’s own purposes. None of those filings gave her a right to use the name against another business. That right comes from federal and common law trademark law, which runs on who used the name first.

This post explains how to trademark a business name in the District, why the filings most owners make do not protect the name, and what a forced rebrand costs.

Four Filings, One Right

Founders tend to treat four separate filings as “getting the name.” Only one of them is a right you can assert against another business.

Entity registration creates the LLC or corporation. The name on the filing is the company’s legal name, and the District’s approval means the District will record it.

Trade name registration is required under D.C. Code § 47-2855.02 for anyone doing business in the District under a trade name. Subsection (d) requires that the trade name be “distinguishable on the records of the Mayor” from entity names, reserved and registered names, other registered trade names, and the names of government agencies. That test asks whether two entries in a database can be told apart. It does not ask whether customers would be confused, and nothing in the section gives the registrant an exclusive right to the name.

Domains and social handles are contracts with a registrar or a platform, awarded first come, first served. Under the federal anticybersquatting provision, 15 U.S.C. § 1125(d), a trademark owner can obtain transfer of a domain registered in bad faith with intent to profit from the mark.

A trademark is the only one of the four that protects the name against other businesses. Two names can be distinguishable in a District database and still be confusingly similar to customers. The District never asked that second question, and it never claimed to.

Where Trademark Rights Come From

In the United States, trademark rights come from use. The first business to use a mark in commerce for particular goods or services generally has priority over a later user, whether or not either one ever filed anything. That is how a founder who has never heard of a competitor can still lose to one.

Rights based on use alone, usually called common law rights, reach only as far as the business actually trades and is known. A Petworth cafe that never registered anything has real rights in its neighborhood and no claim against a cafe in Denver. That limit cuts both ways. A small business can build rights cheaply by opening its doors, and a competitor elsewhere can be building toward a federal registration that will eventually reach into D.C.

From the first day, keep dated proof of first use: the first invoice, the first advertisement, dated photographs of the sign, the launch announcement. In a priority dispute, that file decides the case, and it is very hard to rebuild years later.

What Federal Registration Adds

Registration on the principal register turns a local position into a national one with statutory backing.

Constructive notice. Under 15 U.S.C. § 1072, registration is constructive notice of the registrant’s claim of ownership, so a later adopter cannot claim ignorance of the mark.
Nationwide priority from the filing date. Under § 1057(c), once the mark registers, the filing date counts as constructive use with nationwide priority. That priority does not run against someone who used the mark, or filed for it, before you did.
Evidence. Under § 1057(b), the certificate is prima facie evidence of the mark’s validity, the registrant’s ownership, and the exclusive right to use the mark for the listed goods or services. Without a registration, each of those must be proved with invoices and testimony.
Incontestability. Under § 1065, after five consecutive years of continuous use following registration, with no adverse final decision and no pending proceeding, the owner can file an affidavit within one year after that five-year period and make the right to use the mark incontestable.

Incontestability has limits. Some cancellation grounds in § 1064 survive it, no one acquires an incontestable right in a generic name, and a registration does not cut off valid state-law rights in a name that someone has used continuously since before the registration date. A local business with genuine prior use is not automatically displaced by a later federal registrant, which is why the dated evidence file matters.

Some Names Cannot Be Protected

Courts sort marks along a spectrum that runs from generic to descriptive, suggestive, arbitrary, and fanciful. Judge Friendly set it out in Abercrombie & Fitch Co. v. Hunting World, Inc., 537 F.2d 4, 9 (2d Cir. 1976), and the Supreme Court adopted it in Two Pesos, Inc. v. Taco Cabana, Inc., 505 U.S. 763 (1992). Where a name falls on that spectrum decides how much work it takes to own.

A generic term can never be protected. Nobody owns “Bakery” for a bakery.

Descriptive terms are the trap for local businesses. 15 U.S.C. § 1052(e) bars registration on the principal register of a mark that is merely descriptive of the goods, a mark that is primarily geographically descriptive, and a mark that is primarily merely a surname. D.C. founders most often name a business after its neighborhood or after themselves, and a name built from a neighborhood plus the service, or a surname plus the trade, runs straight into § 1052(e).

Descriptive marks can become registrable. Under § 1052(f), a mark that has become distinctive of the applicant’s goods through use can be registered, and the Director may accept five years of substantially exclusive and continuous use as prima facie evidence of that distinctiveness. Lawyers call this secondary meaning. The cost is five years of building a reputation on a name you do not yet control. Section 1052(f) cannot cure a mark that is geographically deceptively misdescriptive or functional.

Suggestive marks hint at a quality and require a little imagination from the customer. They are protectable without proof of secondary meaning and are the practical choice for most businesses. Arbitrary marks are real words used for unrelated goods, and fanciful marks are invented words. Both are the strongest marks and the easiest to clear.

A descriptive name tells customers what you do on the first day and takes years to protect. A fanciful name is protectable at once and needs marketing to give it meaning. Owners tend to undervalue the second option until a competitor opens down the street under a name they cannot stop.

Clearing the Name Properly

Most founders type the name into the USPTO database, find no exact match, and assume the name is available. That search tests the wrong thing.

Under § 1052(d), registration is refused for a mark that so resembles a registered mark, or a mark or trade name previously used in the United States and not abandoned, as to be likely to cause confusion, to cause mistake, or to deceive. Examiners and courts compare sound, appearance, meaning, and overall commercial impression across related goods and services. A proper clearance looks at:

phonetic and visual variants, misspellings, and translations;
marks for related goods and services as well as identical ones;
pending applications, which carry priority from their filing dates;
unregistered users found through state registrations, business directories, trade press, social platforms, and general web searches; and
whether the name is registrable at all under § 1052(e).

Clearance is a risk assessment. Unregistered users can be found only if they have left a trace, and a search goes stale as new applications are filed. Its value is timing: you learn about the problem while the only cost of changing course is choosing another name.

The District Filings, and What They Do Not Check

A D.C. business collects more name approvals than businesses in most places. The trade name registration, the Basic Business License, and, for a bar or restaurant, the liquor license application all carry the name. The trade name appears on the placard in the window and in the notices sent to neighbors.

Each agency answers its own question: whether the name is distinguishable in its records, whether the applicant qualifies for the license, whether the establishment is properly zoned and noticed. None of them checks the federal trademark register.

Licensed businesses have the most to lose. When the trade name is embedded in a liquor license, a rebrand touches the license record and the placard, plus whatever the Board requires for a name change, on top of the usual costs. We cover the licensing process in Getting a D.C. Liquor License and entity formation in Two Owners, No Operating Agreement. Name clearance belongs before both.

What a Forced Rebrand Costs

Most of the cost of getting this wrong has nothing to do with legal fees. It includes new signage and interior graphics, menus and packaging, uniforms and vehicle lettering, a new domain and email addresses, and updated license records.

The larger loss is harder to see. Months of reviews, map listings, press mentions, and search history stay attached to the abandoned name. Followers do not move cleanly to a new account, and some regular customers stop coming. For a neighborhood business, local recognition is a large share of its value.

The negotiating position also gets worse with time. A senior user who sends a cease-and-desist letter knows how much you have invested in the name, and the longer you have used it, the more a coexistence agreement or license will cost. A clearance search and a federal application usually cost less than one storefront’s signage.

The Order to Do It In

Choose several candidate names, weighted toward suggestive, arbitrary, or invented words. Expect to lose some in clearance.
Run a quick knockout search on each to eliminate obvious conflicts.
Run a full clearance on the survivor, including registrability under § 1052(e).
File the federal application. If the business has not opened, file on an intent-to-use basis under 15 U.S.C. § 1051(b) to lock in the filing date. A business already trading files based on use and submits a specimen.
Then spend money on the name: entity and trade name registration, domain, signage, buildout, and packaging.
Keep the evidence file of first use, starting on the first day.
Calendar the maintenance filings. Under § 1058, a declaration of continued use is due in the year before the sixth anniversary of registration, and registrations renew every ten years under § 1059. More registrations are lost to missed deadlines than to challenges.

If you are already trading under a name you never cleared, start the same way: find out what is out there. Learning about a senior user from your own search leaves you time to choose when and how to respond. Learning about it from their lawyer does not.

The Short Version

Registering an LLC, filing a trade name, and buying a domain let you operate under a name. None of them makes you its owner, and the District’s distinguishable-on-the-records test is not a trademark clearance. Trademark rights come from use, and the first user generally wins. Federal registration adds nationwide priority from the filing date, constructive notice, presumptions of validity and ownership, and eventually incontestability. Pick a name the law can protect, clear it against more than an exact-match search, file before you spend, and keep dated proof of when you started.

The Law Office of Jacobie K. Whitley, PLLC handles trademark clearance and applications alongside business formation and licensing, so the name can be checked while the entity is set up. If you have received a cease-and-desist letter or are about to order signage, call (202) 499-2403.

Whether a name is available, registrable, or infringing depends on the facts of your business and the marks already in use.
