USPTO headquarters

Our headquarters is located in Alexandria, Virginia. Our mission is to drive U.S. innovation, entrepreneurship, and global competitiveness. We provide inventors, entrepreneurs, and small businesses with free resources on how to protect their intellectual property (IP). We work closely with IP practitioners and services, startups, and job-growth accelerators.

Visitor information

The campus is centered in the Madison Building. Most public events at the USPTO are held here, on both the main and concourse levels. The Madison Building is home to the Henry Baker Public Search Facility, the Clara Barton Auditorium, a cafeteria, and the National Inventors Hall of Fame and Museum.

A map (braille accessible) of the Madison Building and campus layout can be found immediately after entering the Madison Building from either of the two main entrances on Dulany Street or Eisenhower Avenue. If you require assistance or directions, we recommend that you proceed to any of the security desks located at either side of the building's atrium.
