Econometric analysis of patent data: The case study of eternal pollutants and bioremediation (1988-2024)
Abstract
The publication studies the correlation between the number of patent applications for bioremediation and for eternal pollutants (PFOS / PFAS), using econometric models as a tool for the calculations. The study is based on data from the European Patent Office, forming time series to which a vector autoregression model (VAR) was then applied. The results show that the number of applications for PFOS is related to the number of applications for bioremediation and the correlation is negative, i.e. when the number of applications for PFOS increases, the number of applications for bioremediation decreases.
