      About these numbers

      Source: USPTO Open Data Portal (Patent File Wrapper and Office Action Rejections APIs). A firm's applications are those listing it as the correspondence address. Rates use applications allowed or abandoned since September 2021; counts include pending applications. Art-unit averages are weighted by the firm's own mix of art units over the same five-year window. Figures describe the firm's aggregate record and are not a measure of any individual attorney, application or client.
