Our partners at Practice Insight have kindly provided us with data on filings in the US, listing the five most productive firms in three separate filing categories. This data has been enhanced significantly this year through machine learning efforts, meaning a lot more applications can be attributed to a particular firm.

In the US, Oblon, McClelland, Maier & Neustadt files the largest number of total applications according to the data (filed between September 2014 and August 2017). This comprises all referral business as well as client-direct applications.

PCT applications

None of the firms listed as handling the most PCT applications (up to August 27, 2017 where the priority date is on or after May 27, 2015) in the US are also in the table for overall applications, perhaps indicating a different client profile for these firms. Fish & Richardson leads the charge here.


The final table gives an indication of which firms received the largest number of referrals in the jurisdiction. That is, the number of applications filed by the given firm between the approximate period of September 2014 and August 2016, where the firm was not responsible for the originating application (in the case of national phase entry and Paris Convention applications), and where that originating application was received from Canada, Japan, UK, Spain, Italy, France, Germany or Korea. As you might expect, the biggest recipients of referrals in the US are also some of the biggest overall handlers of applications, with Oblon once again the leading firm. 

The data are taken from publicly available sources – due to delays in some publications, the numbers may be less than the actual numbers of applications filed.
