The Harrity Analytics Team compiled a list of the top patent law firms that are ranked based on the total number of U.S. utility patents that issued in 2019 where the patent firms were listed on the front of the utility patents, and the art unit is between 3620-3629, 3680-3689, or 3690-3699. Only patent firms that have obtained at least 10 utility patents are included. An attempt was made to correct for typographical errors. Company legal departments were not eliminated from the list.
