How to Register a Trademark in Ohio: Form 555, Fees, and Renewal

To register a trademark in Ohio, you file Form 555 with the Ohio Secretary of State and pay a $125 filing fee, but only after the mark is already in active use on goods sold or services rendered in the state. Registration lasts ten years and can be renewed in ten-year cycles for as long as you keep using the mark.¹²³

Confirm Your Mark Is Eligible

Ohio’s statute defines a trademark as any word, name, symbol, device, or combination used to identify your goods and distinguish them from others. Service marks work the same way for services. Both go through the same application.⁴

The eligibility rule that trips up most applicants is the use requirement. You cannot reserve a mark you intend to use later. The mark must already appear on goods, packaging, labels, or marketing materials, and those goods must be sold or transported within Ohio. For a service mark, the services must already be sold or rendered in Ohio.⁴ This differs from federal registration, which does allow intent-to-use filings.

One boundary worth clearing up before you start: a trademark is not the same thing as a trade name. Your trade name is the name your business operates under, filed on your formation documents or your “doing business as” paperwork. A trademark identifies the source of specific goods or services. Registering one does not register the other. Trade names carry a five-year term; trademarks carry ten.⁵⁶

Run a Clearance Search First

Your application will include a sworn statement that, to your knowledge, no one else has the right to use the mark in Ohio in a form identical to yours or close enough to cause confusion. You also have to confirm no one else holds a federal registration or pending application for a confusingly similar mark covering the same goods or services. A false statement here can get the registration canceled later.⁷

A proper clearance search covers three places. Start with the Ohio Secretary of State’s business database for existing state registrations. Then check the USPTO’s trademark search system for federally registered marks and pending applications, because a conflict there can block your Ohio filing even if nothing matches at the state level. Finally, search the open internet for unregistered marks already in commercial use, since common-law rights can exist without any registration at all.⁸

The legal test for a conflict is “likelihood of confusion,” which weighs visual similarity, phonetic similarity, and how closely the goods or services overlap. An identical match is not the only kind of problem.

Fill Out and File Form 555

Ohio uses Form 555 for both trademark and service mark applications. You can download the PDF from the Secretary of State’s website or file through the Ohio Business Central online portal.¹ The form asks for:

Your full legal name and business address. Corporations list their state of incorporation, partnerships list the general partners, and LLCs list their state of organization.
A written description of the mark exactly as it appears on your specimen. This description is what gets entered into the state database, so phrase it carefully.
A description of the specific goods or services the mark covers, plus the classification number. One application covers one class. A mark that spans multiple classes needs multiple applications, each with its own fee.
The date you first used the mark anywhere and the date you first used it in Ohio.
A specimen showing the mark as it actually appears in commerce: product packaging, a label, a website header, marketing materials, or similar.

The applicant or an authorized officer signs and verifies the application.⁷ The filing fee is $125.² Submit online through Ohio Business Central or by mail to the Secretary of State’s office in Columbus. Online filings generally process faster.

What Happens After You File

The Secretary of State’s office reviews the application to confirm it meets statutory requirements and that the mark does not conflict with existing registrations on file. Online filings may process automatically if nothing is flagged; others require manual review. Approved applications receive a certificate of registration issued under the seal of the Secretary of State.⁹

If something is wrong, you’ll get a notice explaining the problem. The common ones are an incomplete or unusable specimen, a mark too similar to one already registered, or a mismatch between the goods you described and the class number you selected. Most of these are fixable and can be corrected and resubmitted.

Keeping the Registration Alive

An Ohio trademark registration runs for ten years from the date of registration. To keep it active, you file a renewal application within the six months before the registration expires. The renewal needs a statement that the mark is still in use in Ohio, a current specimen, and the renewal fee.³

Miss the window and the registration is canceled automatically. There is no grace period in the statute, and once your registration lapses, another business could potentially register the same or a similar mark. Set a reminder well in advance.¹⁰

Registrations can also be canceled if you voluntarily request it, if a court determines the registration was granted improperly, or if a court finds the mark has become a generic name for the product it represents.¹⁰

Know What Ohio Registration Does and Does Not Cover

An Ohio registration protects your mark inside Ohio’s borders. That’s enough if your customers and operations are entirely in the state: a regional restaurant, a local service provider, a product sold only through Ohio retailers. If you sell online, ship across state lines, or plan to expand, federal registration through the USPTO is what gives you nationwide protection and the right to use the ® symbol.¹¹

The two systems don’t exclude each other. Many businesses file in Ohio for immediate state-level protection while a federal application works through the USPTO’s longer review timeline. Ohio’s filing is simpler and cheaper, and for a business operating only in the state, it provides meaningful legal protection on its own.
