Trademark Tribal Insignia Database

According to an announcement in the Federal Register, the USPTO has created a database containing the official insignia of all federally and state recognized Native American tribes. Tribes can voluntarily submit insignias to this database. The database serves as a reference to help determine the "the registrability of a mark that may be similar to the official insignia of a Native American tribe." An FAQs page is available with further information including how to search for tribal insignias in the larger USPTO Trademark Database.
