Business name, trade name, state mark, and federal mark are different
| Record | What it generally answers | What it does not prove |
|---|---|---|
| Business entity name | Whether an entity record appears in the Delaware business registry. | That the name is free of state, federal, or common-law trademark rights. |
| Trade name or DBA | Whether an operating name is registered under the applicable state or local system. | Ownership of broader trademark rights. |
| State trademark/service mark | Whether a state registration appears in the Delaware mark system. | Nationwide federal protection or the absence of unregistered rights. |
| Federal trademark | Whether a federal application or registration appears in the USPTO system. | A complete legal clearance opinion by itself. |
Recommended search sequence for a Delaware name or mark
Search the official business registry
Look for exact, partial, and similar entity names in the official Delaware business records. This is an entity-record screen, not trademark clearance.
Review the state mark records
Use the state mark search or official information source above. Confirm whether the database includes active registrations only, pending applications, expired records, or images.
Search federal records
Use USPTO Trademark Search for exact words, variations, similar wording, owners, and relevant goods or service classes.
Consider unregistered use
State and federal databases do not necessarily reveal every common-law user. Wider marketplace, domain, directory, and industry research may be needed.
Delaware conditions and limitations
- Delaware state mark registration is separate from Division of Corporations entity-name records.
- State registration is limited to the jurisdiction and does not replace a federal application.
- Applications can require current use, specimens, classification, ownership details, signatures, and separate fees by class.
- Official fees, forms, portals, renewal windows, and evidence requirements can change; recheck before submission.
- Government filing staff generally cannot provide legal advice or resolve priority and infringement disputes.
Use the official Delaware filing source
Start with the official state information page linked above. It is the controlling destination for the current application, fee schedule, specimen instructions, classification rules, renewal process, and payment methods. This directory deliberately does not create a third-party filing form or accept payment.
Source verification
