The indicators presented, (see indicators' description below), refer to inventions filed in one or more jurisdictions (family size 1 or greater) or in two or more jurisdictions (family size 2 or greater). A patent family is defined as the set of all patent applications protecting the same ‘priority' (as defined by the Paris Convention)

For "Diffusion of environment-related technologies" indicators, only "restricted coverage" (i.e. at least 90% of patent office coverage) is used.
