Washington, District of Columbia
Patent attorneys in Washington
Washington, District of Columbia is home to 2,626 USPTO-registered patent practitioners. Working with a local practitioner can streamline in-person meetings for invention disclosures, signing inventor declarations, and reviewing prior-art search results — but every USPTO practitioner is licensed to practice nationally, so a non-local choice is also valid. Local firms with the most USPTO-registered practitioners include Marquez Intellectual Property Law Office, PLLC, Arnold and Porter Kaye Scholer LLP, and Fisher, Christen & Sabol.
