This paper presents a preliminary set of European and international citation data tables designed to enable researchers to become familiar with the subject and undertake a range of analyses. It addresses analytical and statistical issues such as why citations from international searches and...

This paper analyzes firms’ choices regarding the geographic scope of patent protection within the European patent system. We develop an econometric model at the patent level to quantify the impact of office fees and translation costs on firms’ decision to validate a patent in a particular...
