Section 1(a)

Section 1(a) provides a basis for filing under the Lanham Act, allowing an applicant to register a trademark with the U.S. Patent and Trademark Office (USPTO) based on actual use of the mark in commerce. To qualify, the mark must already be in use on goods sold or transported in interstate or international commerce at the time of filing. This distinguishes it from a Section 1(b) intent-to-use application, which permits filing before commercial use begins.

How Section 1(a) works

A Section 1(a) application requires three key elements:

• Date of first use. The earliest date the mark was used anywhere, including within a single state
• Date of first use in commerce. The date the mark was first used in interstate or international commerce, which establishes federal jurisdiction
• Specimen. A real-world example showing the mark as consumers encounter it, such as a product label, packaging, or website screenshot tied to the identified goods or services

The USPTO examines the application for distinctiveness, likelihood of confusion with existing marks, and adequacy of the specimen. If approved, the mark is published for opposition before registration is granted.

Key characteristics and limitations

• Use must exist before filing. The mark must be in active commercial use on all identified goods or services at the time of filing. Filing speculatively under Section 1(a) can render the registration void and subject to cancellation.
• The specimen must reflect genuine use. Mockups, internal documents, or images that do not reflect real commercial transactions are typically rejected. For goods, acceptable specimens include product labels, tags, or packaging. For services, website screenshots showing the mark in connection with the service offering are commonly accepted.
• Ongoing use is required. The owner must continue using the mark in commerce and file maintenance documents to keep the registration active.
• Abandonment risk. Nonuse for three consecutive years creates a rebuttable presumption of abandonment, allowing third parties to petition for cancellation.

Why Section 1(a) matters

The date of first use in commerce becomes legally significant; it can determine priority in disputes between competing trademark claimants, and it is not the same as the application filing date.

Federal registration through Section 1(a) creates a legal presumption of ownership and exclusive nationwide rights to use the mark in connection with the identified goods or services. It also authorizes use of the ® symbol and provides a basis for blocking infringing imports through U.S. Customs.

Section 1(a) vs. Section 1(b)

Section 1(b) allows filing based on a bona fide intention to use a mark before commercial use begins. Under Section 1(b), the applicant must later submit a statement of use or Amendment to Allege Use before registration is granted. Section 1(a) requires use to already exist at filing and skips that additional step. If use has not yet begun on all identified goods or services, Section 1(b) is the appropriate basis.

FAQs about section 1(a)

What counts as "use in commerce" under Section 1(a)?

The mark must appear on goods sold or transported across state or international lines, or be used in connection with services rendered in interstate commerce. Purely local or intrastate use does not meet the federal threshold.

Can a single sale establish use in commerce?

Yes, provided it reflects a genuine commercial transaction rather than a token sale staged to manufacture a filing date. The USPTO and courts distinguish between legitimate first sales and sham transactions.

Is a website screenshot always an acceptable specimen for a service mark?

Only if it shows the mark in direct connection with the specific services identified in the application. A page displaying the mark as a logo without referencing those services is likely to be refused.
