The US Patent & Trademark Office (PTO) re-opened to the public on May 25, 2022. Both the headquarters in Alexandria, Virginia, and the regional offices in Dallas, Texas; Denver, Colorado; Detroit, Michigan and San Jose, California, are now open. The offices had been closed to the public since March 16, 2020, because of the COVID-19 pandemic.

Visitors will be required to complete a health questionnaire and may be denied entry depending on the results of the questionnaire. Local COVID-19 infection rates will determine whether masks are required in each office.

Although the PTO is open to the public, oral hearings before the Patent Trial & Appeal Board and Trademark Trial & Appeal Board will still be conducted by video or telephone. In-person interviews with examiners are now possible, however.
