Thre regression model were constructed using as response variable: Grant for PCT national phase entries patent in the national phase and considering 11 variables related to R&D funding and research personnel as predictor varia-bles. Multivariate linear regression models were estimated using the Bayesian Information Criterion (BIC). The most influential predictive variables were: Total R&D personnel and researchers by performance sectors, sex and fields of science. The regression coefficient was 0.001 with (P <0.05). In conclusion, the mathematical model shows that the most effective predictors of patent-ability are qualified R&D personnel. ER -
