Section 2 refusals
Section 2(f): Acquired Distinctiveness — Trademark Office Action Guide
Section 2(f) allows registration of otherwise unregistrable marks when the applicant proves the mark has become distinctive of their goods or services in commerce.
What the USPTO is saying
The USPTO acknowledges your mark may be descriptive, geographic, or a surname, but is giving you an opportunity to prove it has acquired distinctiveness — also called secondary meaning — through use in commerce.
Why this issue is raised
Marks that start as descriptive or surname-based can become source identifiers over time. Section 2(f) is the pathway to Principal Register registration once that transformation occurs.
How applicants typically overcome it
- Submit a declaration of continuous and substantially exclusive use for five years.
- Provide advertising expenditures, sales figures, and market share data.
- Include consumer survey evidence or media recognition when available.
- Document unsolicited media coverage and industry awards referencing your mark as a brand.
- Show deliberate branding efforts distinguishing your mark from its literal meaning.
