2008, under Ben Klemens

In 2008, under the direction of Ben Klemens, ESP produced the 2008 State of Software Patents (direct link to study) which highlights that non-software companies are now often victims of software patent litigation, and that the cost of software patent litigation to USA companies can be estimated at $11.26 billion per year.

ESP also submitted an amicus curiae brief to the CAFC for the in re Bilski case: esp-bilski-final.pdf.

2009 to present, under Ciarán O'Riordan

In 2009, under the direction of Ciarán O'Riordan, ESP launched the wiki. Development of the wiki has been an ongoing task and is a continual part of all other work done by ESP.

As well as participating in consultations and court cases, ESP provides documentation and raises awareness so that other organisations will also participate.
