The Top Firms for Chemistry and Chemical Engineering


Much like the Juristat Top 100, this list is unique in that it considers both volume and performance. Our ranking is based on four key metrics, as measured from January 1, 2011 to December 31, 2015. These metrics are:

  • Number of Applications Filed
  • Allowance Rate
  • Average Number of Office Actions Before Allowance
  • Average Time of Allowance
  • Overall Juristat ranking

All metrics herein, apart from Applications Filed, are based on public applications disposed between January 1, 2011 to December 31, 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 time. 

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.

Finally, it's important to note that we excluded foreign priority applications in these metrics. This can significantly affect the filing totals shown below.
