The article also provides some data that shows the extent to which the Mexican protection system is used (as of September 2007):
"The NSICS's records show that 805 plant variety applications have been filed in Mexico, of which 37.6% were filed by US applicants and 33.5% by Mexican entities. Dutch, French and German applicants accounted for 11.9%, 8.4% and 3.5% of the applications, respectively. The NSICS has registered 184 applications for maize and 170 applications for roses - these high numbers are explained by the fact that maize originates in Mexico and by the country's wide range of climates for floriculture".[source: "Plant Variety Protection System Continues to Bear Fruit", by Eric Alavez-Mejia (Becerril, Coca & Becerril SC, Mexico), writing in International Law Office].
