This study investigates whether standard patent measures for the importance and basicness of patents are able to distinguish between 'wacky' patents and a control group of randomly drawn patents. Our findings show that forward citations are good predictors of importance. However, the 'wacky'...

The aim of this paper is to analyze the technological activities of Central and Eastern European (CEE) economies and to compare them with the technological activities of other world regions. Using data from the EPO World Wide Statistical Database for the period 1980-2009 the analysis is based on...

Patent-based measures are frequently used as indicators in empirical research on innovation and technology as well as on firms' strategies and organizational choices to characterize inventions or, more generally, innovative activities and the technological capabilities of organizations. A clear...
