A recently published paper by Ernest Miguelez and Carsten Fink exploits a piece of information contained into WIP databases and not yet utilized: inventors' nationality.
The paper (Measuring the International Mobility of Inventors: A new database?) describes a new database mapping migratory patterns of inventors, extracted from information included in patent applications filed under the Patent Cooperation Treaty. and provides a descriptive overview of inventor migration patterns, based on the information contained in the newly constructed database.
