*Our 2017 ranking is now available!*

Juristat is proud to release its ranking of the Top 100 U.S. Patent Firms.  This is the only ranking of U.S. patent prosecution firms that is based on the objective measurement of those firms' performance in front of the United States Patent and Trademark Office.

METHODOLOGY

Our analysis comes from Juristat’s dataset of over 7 million patent applications and is based on a weighted average of the following four criteria:

  • Total number of applications filed (for applications filed between July 2013 and July 2014)
  • Allowance rate (for applications disposed between July 2013 and July 2014)
  • Average number of office actions to allowance (for applications disposed between July 2013 and July 2014)
  • Average time to allowance (for applications disposed between July 2013 and July 2014)

Our analysis was limited to firms that filed at least 400 applications between July 2013 and July 2014.  After the firms’ rankings were calculated for each criterion, we calculated an overall ranking by determining a weighted average of each firm’s four rankings. It is important to note that this method is only one way to measure a firm’s performance and it is not intended to be definitive. There are many different areas in which a firm may excel, which this particular list may not encompass. Juristat’s subscribers can obtain in-depth analysis of law firms’ performance in individual art units, tech centers, or before the PTAB and customize those results to their individual needs.
