Top Patent Firms 2018

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 2018 where the patent firms were listed on the front of the utility patents. We have included only patent firms that have obtained at least 50 utility patents. We made an attempt to correct for typographical errors. We did not eliminate company legal departments from the list.
