The USPTO's Native American tribal insignia database is a part of the Trademark Electronic Search System (TESS). This database records the official tribal insignias of federally or state-recognized American Indian and Alaska Native tribes (Native American tribes).
The USPTO considers the tribal insignias in its database when examining trademarks in pending applications. Tribes who choose to participate allow the USPTO to evaluate whether a trademark may suggest a false connection to their tribal insignia and refuse registration. This gives tribes the benefit of helping to protect their intellectual property and cultural heritage.
There are no fees or forms. For more information about participating in the database, see the refreshed Native American tribal insignia database page on the USPTO website.
