Should I search for state business names and DBA records?
Reviewing state business name records and DBA filings may help identify potential branding conflicts that do not appear in federal trademark records.
A trademark search is a risk-screening step, not a guarantee of availability or approval. Trademark conflicts can arise even when two marks are not identical. The USPTO may consider similarities in sound, appearance, meaning, overall commercial impression, and the relationship between the parties' goods or services.
Federal database searching is important, but it does not necessarily reveal every relevant use. Some businesses may have common-law trademark rights based on actual use in commerce even without a federal registration. That is why broader searches can include state records, business names, websites, domains, social media, and marketplace use.
