Top Patent Firms for 2016

By Paul Harrity & Anna Yee
February 15, 2017

Class of 2016We compiled a list of the top patent firms that are ranked based on the total number of U.S. utility patents that issued in 2016 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. For the list from last year see: Top Patent Firms for 2015.

EDITORIAL NOTE: If your firm is not on this list and your firm did successfully obtain 50 or more U.S. utility patents in 2016 please contact IPWatchdog.

    Nice work, Mr. Harrity.

    Any chance you could generate date about the number of registered practitioners at each of those firms and come up with a patents/practitioner ratio?

  2. kyso March 16, 2017 10:09 am

    Hello, I noticed that some listed firms do not have their rank number listed in the first column. Is there significance to this omission?

    Thank you for your help.

    Kyso-

    When no rank is in the column that denotes a tie, so all those firms are tied for the same place.
