The Largest Patent Prosecution Firms in the US 2016-2021: The latest version of the report is available here 

Who are the largest US patent law firms? How do they differ in patent filing strategies and client structure?

Analyzing their filing statistics, this report is shedding the light on the largest patent law firms in the United States. The figures are based on patent filings since 2014 and contain published patent applications as well as granted patents. If not stated otherwise, the numbers are based on US national filings as well as PCT applications filed by US law firms.

In order to allocate patents to the respective years, we use a mix of patent filing dates and dates of the earliest publication. Whenever an application is itself the priority filing, a direct US foreign filing or a PCT application filed by a US law firm, we refer to the application filing date. However, when a US application is a subsequent of a foreign priority and filed on the PCT route, we use the earliest publication date. This distinction is necessary because, in the raw data, US patents in the latter category usually receive the filing date of the underlying PCT rather than the actual filing date of the US national filing. The earliest publication date is much closer to actual time a US law firm has worked on the national filing.

In most cases, patent information are published 18 months after they have been filed. Therefore, figures cannot yet be complete for 2017 applications/grants. We have included all the latest publications we have available until now.
