Back in January, we released our official ranking of the Top 100 Patent Firms. The Juristat Top 100 is the only ranking of U.S. patent prosecution firms based on objective measurements of firm performance. While the official list excluded foreign priority applications, we received a number of requests asking to see how the rankings would change if those applications were included. Today, we're excited to publish that list. 

Eligibility & Methodology

This ranking is based on four key metrics, as measured from July 1, 2014 to June 30, 2015. These metrics are:

  • Number of Applications Filed
  • Allowance Rate
  • Average Number of Office Actions Before Allowance
  • Average Time to Allowance

All metrics herein, apart from Applications Filed, are based on public applications disposed between July 1, 2014 and June 30, 2015. Applications Filed, as you might have guessed, is based on published applications filed during that time. Finally, to qualify for inclusion, a firm must have filed a minimum of 200 applications during that same period. 

For Applications Filed, we attributed applications to whichever firm was first listed on the application. For the remaining metrics, we attributed applications to whichever firm was listed at disposition. 

After the firms’ rankings were calculated for each of the criterion above, we calculated an overall ranking by determining a weighted average of each firm’s four rankings. This method is but one way to measure a firm’s performance and is not intended to be definitive. There are many different areas in which a firm may excel, which this particular list may not encompass.

As with the original list, design applications were excluded from our analysis.
