How to Trademark a Business Name in New Hampshire (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

You can protect a business name in New Hampshire in two ways: register a state trademark with the New Hampshire Department of State, Corporation Division, or register a federal trademark with the U.S. Patent and Trademark Office (USPTO), whose registrations last 10 years and are renewable indefinitely. Both routes require that you actually use the name as a mark in commerce; forming an LLC or reserving a name does not create trademark rights.

State vs. Federal Trademarks for a New Hampshire Business Name

A trademark protects a name, logo, or slogan that identifies the source of your goods or services. In New Hampshire, you have two separate systems to consider. A New Hampshire state trademark, registered with the New Hampshire Department of State, Corporation Division, protects the mark within New Hampshire. A federal trademark, registered with the USPTO, protects the mark across the entire United States and is generally the stronger, more valuable right. The two systems are independent, and many businesses that operate beyond New Hampshire pursue federal registration.

It is important to distinguish trademark rights from business formation. Filing LLC formation documents or reserving an entity name with the state only stops another entity from registering an identical entity name; it does not give you trademark rights or stop competitors from using a similar brand. Trademark rights come from actually using the name as a mark in commerce and, for the strongest protection, from registering it. See the general trademark overview and the glossary for definitions.

Federal Registration with the USPTO

Federal registration is handled by the USPTO and filed online through the Trademark Center. A federal registration gives you nationwide priority, the right to use the ® symbol, the ability to record the mark with U.S. Customs, and a legal presumption of ownership and validity. Federal applications are examined by an attorney at the USPTO, and the process typically takes many months and can extend beyond a year if issues arise.

You file either based on current use in commerce (Section 1(a)) or a bona fide intent to use (Section 1(b)). Government filing fees are charged per class of goods or services, and the exact amount is set in the USPTO fee schedule. You must identify your goods or services accurately, submit a specimen showing the mark in use, and respond to any office actions the examining attorney issues. Because the federal standard turns on interstate commerce, most businesses selling online or across state lines qualify.

How to Register a Trademark with the New Hampshire Corporation Division

A New Hampshire state trademark is useful if your use is purely local. You apply to the New Hampshire Department of State, Corporation Division, identify the mark and the goods or services it covers, state the date you first used the mark, and submit a specimen along with the state filing fee. Unlike the federal system, state registration generally requires that you are already using the mark in New Hampshire; there is no intent-to-use basis.

1. Search first. Check the USPTO database and New Hampshire records so you do not adopt a mark that conflicts with an existing one.
2. Confirm current use. State registration is based on actual use of the mark on your goods or services in New Hampshire.
3. Classify and prepare a specimen. Identify the correct class(es) and provide a specimen showing the mark as consumers see it.
4. File and pay. Submit the application and the fee set by the New Hampshire Department of State, Corporation Division fee schedule.

New Hampshire and Federal Trademark Fees (2026)

Trademark costs fall into two buckets: the New Hampshire state fee and the federal USPTO fee. The state registration fee is set by the New Hampshire Department of State, Corporation Division and is charged per class of goods or services. Because state fee amounts change, confirm the current figure on the New Hampshire Department of State, Corporation Division's published fee schedule before filing. There is no charge to simply use the ™ symbol on an unregistered mark.

Federal fees are set by the USPTO and are also charged per class. The USPTO periodically restructures its trademark fees, so rely on the current USPTO fee schedule rather than older figures. Budget separately for renewals and maintenance filings, and for any attorney assistance. An EIN is not required to file a trademark, but many brand owners already have one from getting an EIN for their business.

™ vs. ® and Enforcing Your Mark

You may use the ™ symbol with any mark you claim, whether or not it is registered, to signal that you treat the name as a trademark. The ® symbol may only be used once the mark is federally registered with the USPTO; using ® before registration is improper. A New Hampshire state registration does not entitle you to use ®.

Enforcement is up to the owner. A registration strengthens your position, but you still must monitor the market and, if necessary, send cease-and-desist letters or bring an infringement action. Federal registration allows suit in federal court and access to remedies under the Lanham Act. Even without registration, common-law rights can arise from use, but they are limited to the geographic area of actual use and are harder to prove.

Clearing Your Name Before You File

A clearance search is the single most valuable step. Before you invest in branding, search the USPTO trademark database for identical and similar marks in your class, and check New Hampshire entity and trademark records. A name can be unavailable as a trademark even if it is available as an entity name, because the trademark test is likelihood of confusion, not exact identity.

Also confirm the name is not merely descriptive or generic for your goods, which can make it difficult or impossible to register. Distinctive, coined, or arbitrary names are easier to protect. If your search reveals conflicts, adjust the name before filing rather than after. For related steps, see DBA and fictitious names and business licenses, which are separate from trademark rights.

Renewing and Maintaining Your Trademark

Trademarks are not permanent unless you keep using the mark and file the required maintenance documents. A federal registration lasts 10 years and can be renewed indefinitely, but you must file periodic declarations of continued use (including a filing between the fifth and sixth years) and renewals with the USPTO. Missing these deadlines cancels the registration.

A New Hampshire state registration also runs for a term set by state statute and must be renewed through the New Hampshire Department of State, Corporation Division; check your registration certificate and the state statute for the exact term and renewal window. In all cases, continuing to use the mark is essential, because a mark that is abandoned through non-use can be lost. Keep records of your use and calendar every renewal and maintenance deadline.

Trademark Mistakes to Avoid and When to Get Help

Two mistakes cost small businesses the most. The first is building a brand before clearing it - investing in a logo, signage, packaging, and a domain, only to receive a cease-and-desist letter from the owner of a similar mark. A clearance search early, in the relevant class of goods or services, prevents an expensive rebrand later. The second is choosing a name that is merely descriptive of the product, which is a weak mark and often hard to register in New Hampshire or federally.

Other frequent errors include filing in the wrong class, describing the goods or services too narrowly or too broadly, submitting a specimen that does not actually show the mark in use, and misusing the ® symbol before federal registration. Any of these can delay or derail an application. Because the USPTO examination process is adversarial and deadline-driven, many applicants work with a trademark attorney, especially for federal filings or when a conflict appears. If your budget is limited, at minimum complete a thorough search, read the USPTO's application guidance before you file, and keep dated records proving when you first used the mark in commerce. Those records establish your priority if a dispute ever arises.

Frequently Asked Questions

Do I have to trademark my business name in New Hampshire?

No. Trademark registration is optional. You get some common-law rights simply by using the name, but registering a New Hampshire state trademark or a federal trademark with the USPTO gives you stronger, more enforceable protection.

What is the difference between a state and federal trademark in New Hampshire?

A New Hampshire state trademark, filed with the New Hampshire Department of State, Corporation Division, protects the mark only within New Hampshire. A federal trademark, filed with the USPTO, protects it nationwide and lets you use the ® symbol.

Can I use the ® symbol after registering in my state?

No. The ® symbol may only be used with a mark that is federally registered with the USPTO. With a New Hampshire state registration or an unregistered mark, use the ™ symbol instead.

Does forming an LLC protect my business name?

Not as a trademark. Forming an LLC only prevents another entity from registering the same entity name in New Hampshire. Trademark protection requires using the name as a mark and, ideally, registering it.

How long does a trademark last?

A federal registration lasts 10 years and is renewable indefinitely, provided you file the required maintenance documents and keep using the mark. State terms are set by statute and are also renewable.

How much does it cost to trademark a name in New Hampshire?

The New Hampshire state fee is set by the New Hampshire Department of State, Corporation Division and charged per class. Federal fees are set by the USPTO and also charged per class. Check both agencies' current fee schedules before filing.
